Special Note Regarding Forward-Looking Statements

This Quarterly Report on Form 10-Q contains forward-looking statements that involve substantial risks and uncertainties. All statements other than statements of historical facts contained in this Quarterly Report on Form 10-Q, including statements regarding future events or our future results of operations, financial condition, business, strategies, financial needs, and the plans and objectives of management, are forward-looking statements. In some cases you can identify forward-looking statements because they contain words such as “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “might,” “likely,” “plan,” “potential,” “predict,” “project,” “seek,” “should,” “target,” “will,” “would,” or similar expressions and the negatives of those terms. Forward-looking statements are based on information available to our management as of the date of this report and our management's good faith belief as of such date with respect to future events and are subject to a number of risks, uncertainties, and assumptions that could cause actual performance or results to differ materially from those expressed in or suggested by the forward-looking statements. Important factors that could cause such differences include, but are not limited to:

•

our ability to sustain our revenue growth rate, to achieve or maintain profitability, and to effectively manage our anticipated growth;

•

our ability to attract new customers on a cost-effective basis and the extent to which existing customers renew and upgrade their subscriptions;

•

the timing of our introduction of new solutions or updates to existing solutions;

•

our ability to successfully diversify our solutions by developing or introducing new solutions or acquiring and integrating additional businesses, products, services, or content;

•

our ability to maintain and expand our strategic relationships with third parties;

•

our ability to deliver our solutions to customers without disruption or delay;

•

our exposure to liability from errors, delays, fraud, or system failures, which may not be covered by insurance;

•

our ability to expand our international reach;

•

the potential effects on our business of events beyond our control such as the current novel coronavirus (“COVID-19”) pandemic; and

•

other factors discussed in other sections of this Quarterly Report on Form 10-Q, including the sections of this report titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and under Part II, Item 1A. “Risk Factors” and in our Annual Report on Form 10-K for the year ended December 31, 2020 (the “2020 Annual Report”) under Part I, Item 1A, “Risk Factors.”

You should not place undue reliance on our forward-looking statements and you should not rely on forward-looking statements as predictions of future events. The results, events, and circumstances reflected in the forward-looking statements may not be achieved or occur, and actual results, events, or circumstances could differ materially from those described in the forward-looking statements. The forward-looking statements made in this Quarterly Report on Form 10-Q speak only as of the date of this report. We undertake no obligation to update any forward-looking statements made in this report to reflect events or circumstances after the date of this report or to reflect new information or the occurrence of unanticipated events, except as required by law. If we update one or more forward-looking statements, no inference should be drawn that we will make additional updates with respect to those or other forward-looking statements.

Notes to Consolidated Financial Statements

(unaudited)

2.	Significant Accounting Policies

Interim Financial Information

The accompanying consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information. Certain information and disclosures normally included in consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. Accordingly, these consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the related notes for the year ended December 31, 2020, included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020 (the “2020 Annual Report”) filed with the Securities and Exchange Commission (the “SEC”) on February 25, 2021. The accompanying interim consolidated balance sheet as of June 30, 2021, the consolidated interim statements of operations and consolidated statements of comprehensive loss for the three and six months ended June 30, 2021 and 2020, and the consolidated statements of cash flows for the six months ended June 30, 2021 and 2020, are unaudited. The unaudited interim consolidated financial statements have been prepared on a basis consistent with that used to prepare the audited annual consolidated financial statements and include, in the opinion of management, all adjustments, consisting of normal and recurring items, necessary for the fair presentation of the consolidated financial statements. The operating results for the three and six months ended June 30, 2021 are not necessarily indicative of the results expected for the full year ending December 31, 2021.

Prior Period Restatements and Adjustments

During the fourth quarter of 2020, management concluded there was an immaterial error in the Company’s presentation and classification of funds held from customers in the consolidated statements of cash flows for the first three quarters of 2020, impacting previously reported quarterly cash flows. The error related to the adoption of ASU 2016-18, which amends previous guidance to address the classification and presentation of changes in restricted cash and restricted cash equivalents in the consolidated statements of cash flows. Historically, the Company presented the change in funds held from customers as a separate caption within Investing Activities in the consolidated statements of cash flows. While not legally or otherwise contractually restricted, the Company has since concluded that funds held from customers are better classified as generally restricted under the accounting guidance and should be presented as restricted cash equivalents in the consolidated statement of cash flows.

To correct this classification error, amounts previously reported as investing activities for the changes in funds held from customers for the six months ended June 30, 2020 are reported as restricted cash equivalents in the consolidated statement of cash flows. The correction resulted in a change of $0.9 million to net cash used in operating activities and a change of $2.0 million to net cash used in investing activities for the six months ended June 30, 2020. The correction had no impact on the consolidated balance sheets, consolidated statements of operations, or the consolidated statements of comprehensive loss.

The following table presents the consolidated statements of cash flows line items after giving effect to the adoption of ASU 2016-18:

	For the Six Months Ended

Reclassifications

Certain prior period amounts have been reclassified to conform to current period presentation.

Principles of Consolidation

The accompanying consolidated financial statements include those of the Company, its subsidiaries, and a variable interest entity for which the Company is the primary beneficiary, after elimination of all intercompany accounts and transactions.

Segments

The Company operates its business as one operating segment. Operating segments are defined as components of an enterprise about which separate financial information is evaluated regularly by the chief operating decision maker, the Company’s Chief Executive Officer, in deciding how to allocate resources and assess performance. The Company’s chief operating decision maker allocates resources and assesses performance based upon discrete financial information at the consolidated level.

Use of Estimates

The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Significant estimates and judgments related to revenue are described below in the Revenue Recognition Accounting Policy. Significant estimates impacting expenses include: expected credit losses associated with the allowance for doubtful accounts; the measurement of fair values of stock-based compensation award grants; the expected payout level of performance share unit grants; the expected earnout obligations in connection with acquisitions; the expected term of the customer relationship for capitalized contract cost amortization; the valuation and useful lives of acquired intangible assets; the valuation of the fair value of reporting units for analyzing goodwill; and the capitalization and useful life of capitalized software development costs. Actual results could materially differ from those estimates.

Fair Value Measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A three-level fair value hierarchy prioritizes the inputs used to measure fair value. The hierarchy requires entities to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows:

Level 1: Inputs are unadjusted quoted prices in active markets for identical assets or liabilities.

Level 2: Inputs are quoted prices for similar assets and liabilities in active markets or quoted prices for identical or similar instruments in markets that are not active and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets.

Level 3: Inputs are unobservable inputs based on the Company’s assumptions and valuation techniques used to measure assets and liabilities at fair value. The inputs require significant management judgment or estimation.

The Company’s assessment of the significance of an input to the fair value measurement requires judgment, which may affect the valuation of fair value assets and liabilities and their placement within the fair value hierarchy levels. The carrying amounts reported in the consolidated financial statements approximate the fair value for cash equivalents, restricted cash equivalents, trade accounts receivable, trade payables, and accrued expenses, due to their short-term nature.

Acquisitions and Goodwill

The Company’s identifiable assets acquired and liabilities assumed in a business combination are recorded at their acquisition date fair values, which may be considered preliminary and subject to adjustment during the measurement period, which is up to one year from the acquisition date. The valuation requires management to make significant estimates and assumptions, especially with respect to long-lived and intangible assets. Critical estimates in valuing intangible assets include, but are not limited to:

•

future expected cash flows from customer agreements, customer lists, distribution agreements, non-compete agreements, and proprietary content and technology;

•

assumptions about the length of time the brand will continue to be used in the Company’s suite of solutions;

•

royalty rates used to estimate the fees that could be charged to license the proprietary content and technology; and

•

discount rates used to determine the present value of recognized assets and liabilities.

The Company’s estimates of fair value are based upon assumptions it believes to be reasonable, but that are inherently uncertain and unpredictable. Assumptions may be incomplete or inaccurate, and unanticipated events and circumstances may occur.

Goodwill is calculated as the excess of the purchase price over the fair value of net assets acquired, including the amount assigned to identifiable intangible assets. Acquisition-related costs, including advisory, legal, accounting, valuation, and other costs, are expensed in the periods in which these costs are incurred. The results of operations of an acquired business are included in the consolidated financial statements beginning at the acquisition date. Goodwill is tested for impairment annually on October 31, or in the event of certain occurrences. There was no goodwill impairment recorded for the three and six months ended June 30, 2021, respectively, or the year ended December 31, 2020.

The Company estimates the fair value of the earnout liabilities related to business combinations using various valuation approaches, as well as significant unobservable inputs, reflecting the Company’s assessment of the assumptions market participants would use to value these liabilities. The fair value of the earnout is remeasured each reporting period, with any change in the value recorded as other income or expense. The Company recorded expenses from increases in the fair value of earnout liabilities related to business combinations of $1.2 million and $2.5 million for the three and six months ended June 30, 2021, respectively. The Company recorded expenses from increases in the fair value of earnout liabilities related to business combinations of $0.2 million and income from decreases in the fair value of $2.3 million for the three and six months ended June 30, 2020, respectively. (See Note 3).

Long-Lived Assets

The Company evaluates long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying value of these assets may not be recoverable. An impairment is recognized in the event the carrying value of such assets is not recoverable. If the carrying value is not recoverable, the fair value is determined, and an impairment is recognized for the amount by which the carrying value exceeds the fair value. No impairment of long-lived assets occurred in the six months ended June 30, 2021, or 2020.

Acquired Intangible Assets

Acquired intangible assets consist of developed technology, including in-process research and development (“IPR&D”), customer relationships, backlog, database content, noncompetition agreements, and tradenames and trademarks, resulting from the Company’s acquisitions. Acquired intangible assets are recorded at fair value on the date of acquisition and amortized over their estimated useful lives. IPR&D is initially capitalized at fair value as a developed technology intangible asset with an indefinite life and assessed for impairment thereafter. When an IPR&D project is completed, it is amortized over the asset’s estimated useful life.

The Company recognizes an earnout liability for acquisitions of intangible assets that are accounted for as an asset acquisition when the liability is earned and the amount is known. The earnout liability is capitalized as part of the cost of the assets acquired and amortized over the remaining useful life of the asset. Asset acquisition-related costs, primarily legal fees, are capitalized and included in the cost basis of the intangible asset when incurred.

Income Taxes

The Company’s deferred tax assets and liabilities are determined based on temporary differences between the financial reporting and income tax basis of assets and liabilities and are measured using the tax rates that will be in effect when the differences are expected to reverse. A valuation allowance is recorded when it is more likely than not that some of the deferred tax assets will not be realized. The Company assesses its income tax positions and records tax benefits or expense based upon management’s evaluation of the facts, circumstances, and information available at the reporting date.

The objectives of accounting for income taxes are to recognize the amount of taxes payable or refundable for the current period and deferred tax liabilities and assets for the future tax consequences of events that have been recognized in an entity’s financial statements or tax returns. The Company will recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. Judgement is required in assessing the future tax consequences of events that have been recognized in the Company’s consolidated financial statements or tax returns. Variations in the actual outcome of these future tax consequences could materially impact the consolidated financial statements.

Stock-Based Compensation

The Company accounts for stock-based compensation by calculating the fair value of each option, restricted stock unit (“RSU”) or performance share unit (“PSU”) issued under the 2018 Equity Incentive Plan (the “2018 Plan”), or purchase rights issued under the Company’s 2018 Employee Stock Purchase Plan (“ESPP”) at the grant date. The fair value of stock options and purchase rights issued under the ESPP is estimated by applying the Black-Scholes option-pricing model. This model uses the fair value of the Company’s underlying common stock at the measurement date, the expected or contractual term of the option or purchase right, the expected volatility of its common stock, risk-free interest rates, and expected dividend yield of its common stock. The fair value of an RSU or PSU is determined using the fair value of the Company’s underlying common stock on the grant date. The stock-based compensation expense recognized over the performance period for PSUs will equal the fair value of the PSU on the grant date multiplied by the number of PSUs that are earned. Furthermore, the quarterly expense recognized during the performance period for PSUs is based on an estimate of the Company’s future performance and the expected payout level. Changes to management’s estimate of future performance result in adjustments to the stock-based compensation expense for PSUs and are recognized prospectively over the remaining service period. The Company accounts for forfeitures as they occur.

Revenue Recognition

The Company primarily generates revenue from fees paid for subscriptions to tax compliance solutions and fees paid for services performed in preparing and filing tax returns on behalf of its customers. Amounts that have been invoiced are recorded in trade accounts receivable and deferred revenue, contract liabilities, or revenue, depending upon whether the revenue recognition criteria have been met. Revenue is recognized once the customer is provisioned and services are provided in an amount that reflects the consideration the Company expects to be entitled to in exchange for those services. The Company’s revenue recognition policy follows guidance from Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with Customers.

The Company determines revenue recognition through the following five-step framework:

•

Identification of the contract, or contracts, with a customer;

•

Identification of the performance obligations in the contract;

•

Determination of the transaction price;

•

Allocation of the transaction price to the performance obligations in the contract; and

•

Recognition of revenue when, or as, the Company satisfies a performance obligation.

The Company identifies performance obligations in its contracts with customers, which primarily include subscription services and professional services. The transaction price is determined based on the amount which the Company expects to be entitled to in exchange for providing the promised services to the customer, and is comprised of both fixed and variable consideration. The transaction price in the contract is allocated to each distinct performance obligation on a relative standalone selling price basis. Revenue is recognized when performance obligations are satisfied.

Contract payment terms are typically net 30 days. Collectability is assessed based on a number of factors including collection history and creditworthiness of the customer, and the Company may mitigate exposure to credit risk by requiring payments in advance. If collectability of substantially all consideration to which the Company is entitled under the contract is determined to be not probable, revenue is not recorded until collectability becomes probable at a later date.

Revenue is recorded based on the transaction price excluding amounts collected on behalf of third parties, such as sales taxes collected and remitted to governmental authorities.

Subscription and Returns Revenue

Subscription and returns revenue primarily consist of contractually agreed upon fees paid for using the Company’s cloud-based solutions, which include tax calculation and compliance management services, preparing and filing transaction tax returns on behalf of customers, and tax content subscription services. Under most of the Company’s subscription agreements, customers select a price plan that includes an allotted maximum number of transactions over the subscription term. Unused transactions are not carried over to the customer’s next subscription term, and customers are not entitled to refunds of fees paid or relief from fees due in the event they do not use the allotted number of transactions. If customers exceed the maximum transaction level within their price plan, the Company will generally upgrade the customer to a higher transaction price plan or, in some cases, charge overage fees on a per transaction basis. Fees paid for subscription services to tax content vary depending on the volume of tax information accessible to the customer.

The Company’s subscription arrangements do not provide the customer with the right to take possession of the software supporting the cloud-based application services. The Company’s standard subscription contracts are non-cancelable except where contract terms provide rights to cancel in the first 60 days of the contract term. Cancellations under the Company’s standard subscription contracts are not material, and do not have a significant impact on revenue recognized. Tax returns processing services include collection of tax data and amounts, preparation of compliance forms, and submission to taxing authorities. Returns processing services are primarily charged on a subscription basis for an allotted number of returns to process within a given time period.

Revenue is recognized ratably over the contractual term of the arrangement, beginning on the date that the service is made available to the customer. The Company invoices its subscription customers for the initial term at contract signing and at each subscription renewal. Initial terms generally range from 12 to 18 months, and renewal periods are typically one year. Amounts that are contractually billable and have been invoiced, or which have been collected as cash, are initially recorded as deferred revenue or contract liabilities. While most of the Company’s customers are invoiced once at the beginning of the term, a portion of customers are invoiced semi-annually, quarterly, or monthly.

Included in the total subscription fee for cloud-based solutions are non-refundable upfront fees that are typically charged to new customers. These fees are associated with work performed to set up a customer with the Company’s services, and do not represent a distinct good or service. Instead, the fees are included within the transaction price and allocated to the remaining performance obligations in the contract. The Company recognizes revenue for these fees in accordance with the revenue recognition for those performance obligations.

Also included in subscription and returns revenue is interest income on funds held for customers. The Company uses trust accounts at FDIC-insured institutions to provide tax remittance services to customers and collect funds from customers in advance of remittance to tax authorities. After collection and prior to remittance, the Company earns interest on these funds.

Professional Services Revenue

The Company generates professional services revenue from providing tax analysis and services, including tax registrations, voluntary disclosure agreements, nexus studies, and backfiling services. Additionally, the Company provides configurations, data migrations, integration, and training for its subscriptions and returns products. The 2020 acquisitions of Transaction Tax Resources, Inc. (“TTR”) and Business Licenses, LLC (“Business Licenses”) (see Note 5) expanded the scope of professional services to include

business licenses and registration services and tax refund claims and recovery assistance. The Company invoices for professional service arrangements on a fixed fee, milestone, or time and materials basis. The transaction price allocated to professional services performance obligations is recognized as revenue as services are performed or upon completion of work.

Judgments and Estimates

The Company’s contracts with customers often include obligations to provide multiple services to a customer. Determining whether services are considered distinct performance obligations that should be accounted for separately from one another requires judgment. Subscription services and professional services are both distinct performance obligations that are accounted for separately.

Judgment is required to determine the standalone selling price (“SSP”) for each distinct performance obligation. The Company allocates revenue to each performance obligation based on the relative SSP. The Company determines SSP for performance obligations based on overall pricing objectives, which take into consideration observable prices, market conditions and entity-specific factors. This includes a review of historical data related to the services being sold and customer demographics. The Company uses a range of amounts to estimate SSP for performance obligations. There is typically more than one SSP for individual services due to the stratification of those services by information, such as size and type of customer.

Assets Recognized from the Costs to Obtain a Contract with a Customer

The Company recognizes an asset for the incremental costs of obtaining a contract with a customer if it expects the benefit of those costs to be longer than one year. The Company has determined that certain costs related to employee sales incentive programs (sales commissions) and partner commission programs represent incremental costs of obtaining a contract and therefore should be capitalized. Capitalized costs are included in deferred commissions on the consolidated balance sheets. These deferred commissions are amortized over an estimated period of benefit, generally six years. The Company determines the period of benefit by taking into consideration past experience with customers, the expected life of acquired technology that generates revenue, industry peers, and other available information. The period of benefit is generally longer than the term of the initial contract because of anticipated renewals. The Company elected to apply the practical expedient to recognize the incremental costs of obtaining a contract as an expense if the amortization period of the asset would have been one year or less.

Leases

Leases arise from contracts which convey the right to control the use of identified property or equipment for a period of time in exchange for consideration. The Company’s leasing arrangements are primarily for office space used to conduct operations. The Company determines whether an arrangement is or contains a lease at the inception date, based on whether there is an identified asset and whether the Company controls the use of the identified asset throughout the period of use. Leases commence when the lessor makes the asset available for use.

Leases are classified at commencement as either operating or finance leases. All the Company’s leases are classified as operating leases. Rent expense for operating leases is recognized on the straight-line method over the term of the agreement beginning on the lease commencement date. Lease-related costs, which are variable rather than fixed, are expensed in the period incurred. Variable lease costs consist primarily of common area maintenance and utilities costs for the Company’s office spaces that are due based on the actual costs incurred by the landlord. Lease payments that depend on an index or a rate are measured using the index or rate at the commencement date and are included in operating lease costs. Subsequent increases to lease payments due to a change in the index or rate are expensed as a variable lease cost.

Recently Adopted Accounting Standards

ASU 2019-12

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which amends the existing guidance relating to the accounting for income taxes. This ASU is intended to simplify the accounting for income taxes by removing certain exceptions to the general principles of accounting for income taxes and to improve the consistent application of U.S. GAAP for other areas of accounting for income taxes by clarifying and amending existing guidance. This ASU is effective for fiscal years beginning after December 15, 2020, with early adoption permitted. The Company adopted the guidance on January 1, 2021 and the adoption of this new guidance does not have a material effect on its consolidated financial statements.

New Accounting Standards Not Yet Adopted

There are no new accounting standards that have not yet been adopted.

Earnout Liability

Earnout liabilities recorded in connection with an acquisition accounted for as a business combination under ASC 805 are recorded at estimated fair value on a recurring basis. Business combinations are discussed in Note 5. Earnouts recorded in connection with asset acquisitions are recorded as earnout payments become known. As such, earnouts related to asset acquisitions, which are discussed in Note 7, are not included in these fair value disclosures.

Earnout liabilities are classified as Level 3 liabilities because the Company uses unobservable inputs to value them, reflecting its assessment of the assumptions market participants would use to value these liabilities. Changes in the fair value of earnout liabilities are recorded in other (income) expense, net in the consolidated statements of operations.

The Company estimates the fair value of earnout liabilities for business combinations using either probability-weighted discounted cash flows and Monte Carlo simulations or a scenario-based approach. The earnout liability associated with the acquisition of Davo Technologies LLC (“Davo”) is based on the achievement of specific revenue growth thresholds through March 2023. As of June 30, 2021, the earnout liability associated with the acquisition of Davo was valued utilizing a discount rate of 8%. The Davo discount rate was calculated using a top-down approach based on the internal rate of return, risk-free rate, and operating leverage factor. The earnout liability associated with the 2020 acquisition of TTR is based on the achievement of specific revenue growth thresholds through December 2022. As of June 30, 2021, the earnout liability associated with the acquisition of TTR was valued utilizing a discount rate of 13%. The TTR discount rate was calculated using the build-up method with a risk-free rate commensurate with the term of the earnout based on the equity and asset betas, size premium, and the Company’s specific risk premium, as well as the market risk premium using a bottom-up approach. The earnout liability associated with the 2020 acquisition of Business Licenses is based on the achievement of certain performance metrics through November 2024. As of June 30, 2021, the earnout liability associated with the acquisition of Business Licenses was valued utilizing a discount rate of 4.4% based on the Company’s estimated pre-tax cost of debt. The Business Licenses earnout was assumed by management to have a high probability of achievement.

The earnout period for the 2019 acquisition of Portway International Inc. (“Portway”) ended as of January 31, 2021 and did not result in any additional earnout payments due to not meeting the revenue targets.

A reconciliation of the beginning and ending balances of recurring fair value measurements recognized in the accompanying consolidated balance sheets using significant unobservable (Level 3) inputs, is as follows (in thousands):

	Three Months Ended June 30,

Assets and liabilities measured at fair value on a non-recurring basis

The Company’s non-financial assets and liabilities, which include goodwill, intangible assets, long-lived assets and deferred revenue, and the Company’s liabilities for the accrued purchase price related to acquisitions, are not required to be measured at fair value on a recurring basis. The estimation of fair value for these assets and liabilities requires the use of significant unobservable inputs, and as a result, the Company classifies these assets and liabilities as Level 3 within the fair value hierarchy. During the three and six months ended June 30, 2021, assets acquired and liabilities assumed in business combinations, including trade accounts receivable, property and equipment, intangible assets, and deferred revenue, were measured at fair value on the date of the acquisition. In addition, certain operating lease right-of-use assets were measured at fair value on the date of acquisition or the date of lease commencement or modification, as applicable. There were no additional fair value measurements of these assets during the first half of 2021, except as discussed in Note 5.

5.	Acquisitions of Businesses

April 2021 Acquisition of Inposia

On April 1, 2021, the Company acquired the outstanding equity of Inposia Solutions, GmbH (“Inposia”) under a Share Purchase Agreement (the “Inposia Purchase”). Inposia is a German software company that delivers e-invoicing, digital tax reporting, and system and data integration to support digital transformation efforts and address real-time compliance requirements for businesses. Inposia will build upon Avalara’s existing e-invoicing capabilities in Brazil and India to support customers worldwide with real-time compliance. The Company accounted for the Inposia Purchase as a business combination. Acquisition-related costs of $1.3 million were primarily for legal and due-diligence related fees and were recorded in general and administrative expense, of which $1.0 million was incurred in the second half of 2020 and $0.3 million was incurred in the first half of 2021.

The total consideration transferred related to this transaction was €31.9 million (or approximately $37.6 million using the exchange rate on April 1, 2021), consisting of $12.2 million cash paid at closing, a $2.4 million cash deposit paid in the fourth quarter of 2020, 164,416 shares of the Company’s common stock paid at closing with an acquisition date fair value of $23.0 million. A portion of shares issued are held in escrow as of June 30, 2021, and will be released to the Inposia shareholders over the next 18 months, subject to reduction for certain indemnification and other potential obligations of the Inposia shareholders. The shares held in escrow are considered issued and outstanding, and are recorded in shareholders’ equity on the consolidated balance sheet as of June 30, 2021.

Preliminary estimated fair values of the assets acquired and the liabilities assumed in the Inposia Purchase as of the acquisition date are provided in the following table (in thousands):




Assets acquired:
Cash and cash equivalents	$	1,264
Trade accounts receivable		1,767
Other current assets		268
Operating lease right-of-use assets		928
Property and equipment		98
Developed technology, customer relationships, and other intangibles		12,684
Goodwill		27,702
Other noncurrent assets		35
Total assets acquired		44,746
Liabilities assumed:
Trade payables and accrued expenses		1,340
Deferred revenue		811
Other liabilities, noncurrent		106
Operating lease liabilities		928
Deferred tax liability		3,919
Total liabilities assumed		7,104
Net assets acquired	$	37,642

The estimated fair values for acquired intangible assets, deferred revenue, and deferred tax liabilities are preliminary in nature and subject to adjustment when the necessary information is available to complete the valuation.

The carrying amount of trade accounts receivable acquired in the Inposia Purchase approximates the fair value. The fair value of deferred revenue was estimated using the income approach, utilizing a bottom-up method that estimated the costs required to support the remaining obligations plus an assumed profit margin, and discounted to present value utilizing a risk-adjusted discount rate of 4.0%.

The Company utilizes different valuation approaches and methodologies to determine the fair value of acquired intangible assets. The weighted-average amortization period for all intangibles acquired in the Inposia Purchase is 5.9 years. A summary of the valuation methodologies, significant assumptions, and estimated useful lives of acquired intangible assets in the Inposia Purchase are provided in the below table (in thousands):

Intangible	Assigned Value		Valuation Methodology	Discount Rate			Estimated Useful Life
Customer relationships	$	1,585	Multi-period excess earnings-income approach		18.5	%	8 years
Developed technology		9,572	Relief from royalty-income approach		18.5	%	6 years
Noncompetition agreements		1,292	With-and-without valuation-income approach		18.5	%	3 years
Tradename		235	Relief from royalty-income approach		18.5	%	3 years

The excess of the purchase price over the net identified tangible and intangible assets is $27.7 million and has been recorded as goodwill, which includes synergies expected from the combined service offerings and the value of the assembled workforce. The goodwill is not expected to be deductible for tax purposes.

For the period from the date of the Inposia Purchase through June 30, 2021, revenue was $2.1 million and pre-tax loss was $0.5 million from the Inposia business.

April 2021 Acquisition of Davo

On April 20, 2021, the Company acquired substantially all the assets of Davo under an Asset Purchase Agreement (the “Davo Purchase”). Davo helps emerging small businesses automate the daily and ongoing requirements for sales tax. As a result of the acquisition, Davo extends Avalara’s ability to provide integrated sales tax compliance processes to alleviate the burden of compliance on small businesses. The Company accounted for the Davo Purchase as a business combination. Acquisition-related costs of $0.1 million were primarily for legal and due-diligence related fees and were recorded in general and administrative expense.

The total consideration transferred related to this transaction was $55.0 million, consisting of $23.5 million cash paid at close, a $0.3 million cash deposit paid in the first quarter of 2021, an acquisition holdback with a fair value upon acquisition of $2.6 million, and an earnout provision with a fair value upon acquisition of $28.6 million. The acquisition holdback represents an additional $2.6 million of cash to be paid Davo shareholders over the next 18 months, subject to reduction for certain indemnifications and other potential obligations of Davo shareholders. The acquisition holdback liability is recorded in accrued purchase price related to acquisitions, noncurrent portion on the consolidated balance sheet as of June 30, 2021. The earnout will be calculated as a multiple of certain performance metrics during the 12-month measurement periods ending March 31, 2022 and 2023, and there is not a stated minimum or maximum payment required under the earnout. Of the earnout liability recognized at the date of the business combination, $14.2 million is recorded in accrued earnout liabilities, current and $14.4 million is recorded in accrued earnout liabilities, noncurrent. The earnout liability is adjusted to fair value quarterly (See Note 3).

Preliminary estimated fair values of the assets acquired and the liabilities assumed in the Davo Purchase as of the acquisition date are provided in the following table (in thousands):

Assets acquired:
Cash and cash equivalents	$	198
Funds held from customers		12,464
Trade accounts receivable		119
Other current assets		58
Operating lease right-of-use assets		46
Developed technology, customer relationships, and other intangibles		6,427
Goodwill		48,426

Deferred revenue		75
Operating lease liabilities		46
Customer fund obligations		12,464
Total liabilities assumed		12,702
Net assets acquired	$	55,038

The estimated fair values for acquired intangible assets and earnout consideration are preliminary in nature and subject to adjustment, when the necessary information is available to complete the valuation.

The carrying amount of trade accounts receivable acquired in the Davo Purchase approximates the fair value.

7.0 years.A summary of the valuation methodologies, significant assumptions, and estimated useful lives of acquired intangible assets in the Davo Acquisition are provided in the below table (in thousands):

Intangible	Assigned Value		Valuation Methodology	Discount Rate			Estimated Useful Life

The excess of the purchase price over the net identified tangible and intangible assets is $48.4 million and has been recorded as goodwill, which includes synergies expected from the combined service offerings and the value of the assembled workforce. The goodwill is expected to be deductible for tax purposes.

For the period from the date of the Davo Purchase through June 30, 2021, revenue was $0.5 million and pre-tax loss was $0.4 million from the Davo business.

October 2020 Acquisition of Transaction Tax Resources

On October 5, 2020, the Company acquired the outstanding equity of TTR under a Merger Agreement (the “TTR Merger”). TTR is a leading provider of tax content, research, consulting, and automation tools in the U.S., with products that include software solutions for companies and governments. As a result of the acquisition, the Company expanded its tax content, added new product offerings, and reached new customer segments. The Company accounted for the TTR Merger as a business combination.

The total consideration related to this transaction was $370.1 million, consisting of $294.0 million in cash paid at closing, acquisition holdbacks with a fair value upon acquisition of $57.3 million, and an earnout provision with a fair value upon acquisition of $18.9 million. The acquisition holdbacks represent the present value of an additional $57.3 million of cash to be paid up to three years following the acquisition, subject to reduction for certain indemnifications and other potential obligations of the TTR shareholders, discounted utilizing a risk-free discount rate of 0.13%. The earnout is payable to TTR’s founder and shareholder no later than February 2023. The maximum earnout payment is $26.4 million and is based on the achievement of certain TTR revenue growth performance metrics during the 2021 and 2022 fiscal years. The potential amount of all future payments that could be required under the earnout is between $0 and $26.4 million. The earnout was recognized at fair value at the date of the business combination and is adjusted to fair value quarterly (see Note 3).

Measurement period adjustments recognized in the first quarter of 2021 related to the finalization of the estimated fair values for customer relationships, contract backlog, and earnout liability, and a net working capital adjustment. A reconciliation of preliminary total consideration as of December 31, 2020 and total consideration as of June 30, 2021 is presented below (in thousands):

	Previously		Purchase Price Allocation

The carrying amount of trade accounts receivable acquired in the TTR Merger was $7.2 million and was recorded at $6.0 million on the date of acquisition to approximate the fair value. The fair value of deferred revenue was estimated using the income approach, utilizing a bottom-up method that estimated the costs required to support the remaining obligations plus an assumed profit margin, and discounted to present value utilizing a risk-adjusted discount rate of 3.5%.

The Company utilizes different valuation approaches and methodologies to determine the fair value of acquired intangible assets. The weighted-average amortization period for all intangibles acquired in the TTR Merger is 4.7 years. The weighted-average amortization period for developed technology intangibles acquired in the TTR Merger is 4.0 years. A summary of the valuation methodologies, significant assumptions, and estimated useful lives of acquired intangible assets in the TTR Merger are provided in the below table (in thousands):

Intangible	Previously Reported Assigned Value As of December 31, 2020		Purchase Price Allocation Measurement Period Adjustment			As Reported Assigned Value		Valuation Methodology	Discount Rate	Estimated Useful Life
Customer relationships	$	26,000	$	(5,000	)	$	21,000	Multi-period excess earnings-income approach	18%	6 years

Noncompetition agreements		1,800		—			1,800	With-and-without valuation-income approach	19%	5 years

The excess of the purchase price over the net identified tangible and intangible assets is $335.6 million and has been recorded as goodwill, which includes synergies expected from the combined service offerings and the value of the assembled workforce. The goodwill is not expected to be deductible for tax purposes.

The acquisition holdback liability is recorded in accrued purchase price related to acquisitions, with $37.7 million included in the current portion on the consolidated balance sheet as of June 30, 2021, and $19.9 million and $37.7 million included in the current and noncurrent portions, respectively, on the consolidated balance sheet as of December 31, 2020. A portion of the acquisition holdback liability in the amount of $19.9 million was settled in the first half of 2021, resulting in additional cash paid of $0.8 million in the first quarter and $18.8 million paid in the second quarter to sellers.

November 2020 Acquisition of Business Licenses

On November 5, 2020, the Company acquired substantially all of the assets of Business Licenses under an Asset Purchase Agreement (the “Business Licenses Purchase”). Business Licenses is a leading provider of license content, software, management, and services that automate and streamline business license compliance for companies of all sizes. As a result of the acquisition, the Company expanded its product offerings to include complementary compliance solutions beyond tax, such as business licenses and registrations. The Company accounted for the Business Licenses Purchase as a business combination.

The total consideration transferred related to this transaction was $93.3 million, consisting of $64.8 million paid in cash at closing, an acquisition holdback with a fair value upon acquisition of $11.1 million, and an earnout provision with a fair value upon acquisition of $17.4 million. The acquisition holdback represents the present value of an additional $11.1 million of cash to be paid after 18 months to Business Licenses’ shareholders, subject to reduction for certain indemnification obligations, discounted utilizing a risk-free discount rate of 0.13%. The maximum earnout payment of up to $20.7 million will be paid, in shares of the Company’s common stock, to Business Licenses’ shareholders following the achievement of certain Business Licenses operating performance metrics during the four years following the acquisition. The potential amount of all future payments that could be required under the earnout is between $0 and $20.7 million. The earnout was originally recognized at fair value at the date of the business combination is adjusted to fair value quarterly (see Note 3).

Measurement period adjustments recognized in the first quarter of 2021 related to the finalization of the estimated fair value of the earnout liability and a net working capital adjustment. A reconciliation of preliminary total consideration as of December 31, 2020 and total consideration as of June 30, 2021 is presented below (in thousands):

Noncompetition agreements		500	With-and-without valuation-income approach	19.5%	5 years
Tradename		400	Relief from royalty-income approach	19.5%	1 year

The excess of the purchase price over the net identified tangible and intangible assets is $72.1 million and has been recorded as goodwill, which includes synergies expected from the combined service offerings and the value of the assembled workforce. The goodwill is expected to be deductible for tax purposes.

The acquisition holdback liability of $11.1 million and $11.4 million is recorded in accrued purchase price related to acquisitions, current portion on the consolidated balance sheet as of June 30, 2021 and noncurrent portion as of December 31, 2020, respectively.

December 2020 Acquisition of Impendulo

On December 1, 2020, the Company acquired the shares of Impendulo (the “Impendulo Purchase”). Impendulo is a London-based provider of insurance tax compliance solutions and offers insurance tax compliance management technology and services, specializing

in support for multi-national insurance companies. With the acquisition of Impendulo, the Company expands its product offerings to include insurance premium tax compliance. The Company accounted for the Impendulo Purchase as a business combination.

The total consideration transferred related to this transaction was $14.0 million, consisting of $11.7 million paid in cash at closing, $1.2 million paid in the Company’s common stock, and an additional $1.1 million that was paid in the first quarter of 2021 based on final revenue metrics achieved up to the date of acquisition.

Disclosures Related to Contracts with Customers

Timing may differ between the satisfaction of performance obligations and the invoicing and collection of amounts related to contracts with customers. Liabilities are recorded for amounts that are collected in advance of the satisfaction of performance obligations. To the extent a contract exists, as defined by ASC 606, these liabilities are classified as current and non-current deferred revenue. To the extent that a contract does not exist, as defined by ASC 606 (e.g., customer agreements with non-standard termination rights), these liabilities are classified as contract liabilities. Contract liabilities are transferred to deferred revenue at the point in time when the criteria that establish the existence of a contract are met.

Finite-lived intangible assets are amortized over their estimated useful life. Finite-lived intangible assets amortization expense was $6.2 million and $10.6 million for the three and six months ended June 30, 2021, respectively, and $1.6 million and $3.5 million for the three and six months ended June 30, 2020, respectively.

Acquisitions of finite-lived intangible assets

In May 2018, the Company acquired developed technology to facilitate cross-border transactions (e.g., tariffs and duties), from Tradestream Technologies Inc. and Wise 24 Inc. (the “Sellers”) for cash and common stock. Total consideration for the purchase includes an earnout computed on future billings recognized by the Company over the next six years, up to a maximum of $30.0 million. The earnout is payable in cash or common stock at the end of each six-month measurement period ending on June 30 or December 31 through 2023.Through June 30, 2021, the sellers have earned approximately $1.6 million under the earnout provision since the acquisition date. An earnout liability of $0.6 million was recorded within the current portion of accrued earnout liabilities as of June 30, 2021 for the earnout period ending June 30, 2021 and is expected to be paid in cash to the sellers in the third quarter of 2021.

Goodwill

Changes in the carrying amount of goodwill for the six months ended June 30, 2021 are summarized as follows (in thousands):

Balance—December 31, 2020	$	513,234
Measurement period adjustment - acquisition of Transaction Tax Resources		8,526
Measurement period adjustment - acquisition of Business Licenses		(1,634	)
Measurement period adjustment - acquisition of Impendulo		425
Acquisition of Davo		48,426
Acquisition of Inposia		27,702
Cumulative translation adjustments		(5	)
Balance—June 30, 2021	$	596,674

Goodwill is tested for impairment annually on October 31 at the reporting unit level or whenever circumstances occur indicating goodwill might be impaired. The impairment test involves comparing the fair value of each reporting unit to its carrying value, including goodwill. Fair value reflects the price a market participant would be willing to pay in a potential sale of the reporting unit. If the fair value exceeds carrying value, the Company will conclude that no goodwill impairment has occurred. If the carrying value of the reporting unit exceeds its fair value, the Company will recognize an impairment loss in an amount equal to the excess, not to exceed the carrying value. The Company has three reporting units for goodwill impairment testing consisting of its U.S., European, and Brazilian operations. As of June 30, 2021, the Brazilian reporting unit had no associated goodwill.

Leases

Total lease cost, net of sublease income, was $4.4 million and $8.3 million for the three and six months ended June 30, 2021, respectively, and $3.9 million and $7.7 million for the three and six months ended June 30, 2020, respectively. Sublease income was $0.4 million and $0.8 million for the three and six months ended June 30, 2021, respectively and $0.4 million and $0.8 million for the three and six months ended June 30, 2020, respectively. Leases that commenced in the first half of 2021 increased operating lease right-of-use assets by $1.7 million.

9.	Commitments and Contingencies

Contingencies

Loss contingencies may arise in connection with the ordinary conduct of the Company’s business activities. The Company considers all loss contingencies on a quarterly basis and based on known facts assesses whether potential losses are considered reasonably possible, probable, and estimable. The Company establishes an accrual for loss contingencies when the loss is both probable and reasonably estimable. If the estimated loss is a range of potential outcomes and there is no better estimate within the range, management accrues the amount at the low end of the range. These accruals represent management’s estimate of probable losses and, in such cases, there may be an exposure to loss in excess of the amounts accrued. Significant judgment is required to determine both likelihood of there being a probable loss and the estimated amount of a loss. If a loss contingency is not both probable and reasonably estimable, the Company does not establish an accrual, but will evaluate other disclosure requirements and continue to monitor the matter for developments that would make the loss contingency both probable and reasonably estimable. The ultimate outcome of any litigation relating to a loss contingency is uncertain and, regardless of outcome, litigation can have an adverse impact on the Company because of defense costs, negative publicity, diversion of management resources and other factors.

In its standard subscription agreements, the Company has agreed to indemnification provisions with respect to certain matters. Further, from time to time, the Company has also assumed indemnification obligations through its acquisition activity. These indemnification provisions can create a liability to the Company if its services do not appropriately calculate taxes due to tax jurisdictions, or if the Company is delinquent in the filing of returns on behalf of its customers. Although the Company’s agreements have disclaimers of warranties that limit its liability (beyond the amounts the Company agrees to pay pursuant to its indemnification obligations and guarantees, as applicable), a court could determine that such disclaimers and limitations are unenforceable as a matter of law and hold the Company liable for certain errors. Further, in some instances the Company has negotiated agreements with specific customers or assumed agreements in connection with the Company’s acquisitions that do not limit this liability or disclaim these warranties. It is not possible to reasonably estimate the potential loss under these indemnification arrangements.

10.	Shareholders’ Equity

Authorized Capital—Common Stock and Preferred Stock

Under the Amended and Restated Articles of Incorporation, which became effective in June 2018, the Company is authorized to issue two classes of stock designated as common stock and preferred stock.

11.	Equity Incentive Plans

The Company has stock-based compensation plans that provide for the award of equity incentives, including stock options, stock awards, RSUs, PSUs, and purchase rights. As of June 30, 2021, the Company had stock options outstanding under the 2018 Plan and the 2006 Equity Incentive Plan (the “2006 Plan”), RSUs and PSUs outstanding under the 2018 Plan, and purchase rights issued under the ESPP. The 2018 Plan became effective in connection with the Company’s IPO at which time the 2006 Plan was terminated. Outstanding awards under the 2006 Plan continue to be subject to the terms and conditions of the 2006 Plan.

As of June 30, 2021, 4,046,624 shares were subject to outstanding awards and 12,213,759 shares were available for issuance under the 2018 Plan. As of June 30, 2021, 1,814,676 shares were subject to outstanding stock options under the 2006 Plan.

Stock-Based Compensation

The Company recognized total stock-based compensation cost related to equity incentive awards as follows (in thousands):

	For the Three Months Ended June 30,				For the Six Months Ended June 30,
	2021		2020		2021		2020
Stock-based compensation cost:
Stock options	$	3,074	$	4,159	$	6,297	$	8,008

A summary of options outstanding and vested as of June 30, 2021 is as follows:

	Options Outstanding				Options Vested and Exercisable
Exercise	Number		Weighted Average		Number Vested		Weighted Average
Prices	Outstanding		Life (in Years)		and Exercisable		Life (in Years)

		2,967,034				2,013,423

The total intrinsic value of options exercised during the six months ended June 30, 2021 and 2020 was $70.7 million and $131.2 million, respectively.

There were no options granted during the six months ended June 30, 2021. The weighted average grant date fair value of options granted during the six months ended June 30, 2020 was $30.06 per share. During the six months ended June 30, 2021, 623,337 options vested. There were 953,611 options unvested as of June 30, 2021.

As of June 30, 2021, $17.2 million of total unrecognized compensation cost related to stock options was expected to be recognized over a weighted average period of approximately 1.9 years.

All options given to participants, including employees and non-employee directors, are measured based on the grant date fair value of the awards and recognized in the consolidated statements of operations over the period during which the participant is required to perform services in exchange for the award. The vesting period is generally four years for employees and one year for non-employee directors. For the options granted during the periods presented, the fair value of options was estimated using the Black-Scholes option-pricing model with the following assumptions:

	For the Three Months Ended June 30,			For the Six Months Ended June 30,
	2021		2020	2021		2020
Fair market value of common stock		—	$66.26 - 99.65		—	$66.26 - 99.65
Volatility		—	43%		—	43%
Expected term		—	5-6 years		—	5-6 years
Expected dividend yield		—	n/a		—	n/a
Risk-free interest rate		—	0.33% - 0.51%		—	0.33% - 1.25%

Options are granted with an exercise price per share not less than the per share fair market value of the Company’s common stock on the grant date. The fair market value per share of the Company’s common stock for purposes of determining stock-based compensation is the closing price of the Company’s common stock as reported on the applicable grant date.

Expected volatility for stock options is based on a combination of annualized daily historical volatility of the Company’s stock price and the historical and implied volatility of comparable publicly traded companies over a similar expected term.

The expected term represents the period that the Company’s stock-based awards are expected to be outstanding. Given the Company’s relative inexperience of significant exercise activity, the expected term assumptions were determined based on application of the simplified method of expected term calculation by averaging the contractual life of option grants and the vesting period of such grants. This application, when coupled with the contractual life of ten years and average vesting term of four years for employees and one year for non-employee directors, creates an expected term of six years and five years, respectively.

The Company has not paid and does not expect to pay dividends.

The risk-free interest rate was based on the rate for a U.S. Treasury zero-coupon issue with a term that closely approximates the expected life of the option grant at the date nearest the option grant date.

Restricted Stock Units

The following table summarizes RSU activity for the Company’s stock-based compensation plans for the six months ended June 30, 2021:

				Weighted
				Average
				Grant Date Fair
	Restricted Stock Units			Value Per Share
RSUs outstanding as of January 1, 2021		2,359,063		$	70.17
RSUs granted		949,563			131.96
RSUs vested		(421,579	)		60.76
RSUs cancelled		(113,413	)		73.04
RSUs outstanding as of June 30, 2021		2,773,634		$	92.63

Stock-based compensation cost for RSUs is recognized on a straight-line basis in the consolidated statements of operations over the period during which the participant is required to perform services in exchange for the award, based on the fair value of the Company’s underlying common stock on the grant date. The vesting period of each RSU grant is generally four years for employees and one year for non-employee directors. As of June 30, 2021, $231.5 million of total unrecognized compensation cost related to RSUs was expected to be recognized over a weighted average period of approximately 3.1 years.

Performance Share Units

The following table summarizes PSU activity for the Company’s stock-based compensation plans for the six months ended June 30, 2021:

			Weighted
			Average
			Grant Date Fair
	Performance Share Units		Value Per Share
PSUs outstanding as of January 1, 2021		—	$	—
PSUs granted		120,632		147.39
PSUs vested		—		—
PSUs cancelled		—		—
PSUs outstanding as of June 30, 2021		120,632	$	147.39

During the first quarter of 2021, PSUs were granted for the first time and are intended to replace stock option grants for executives. Stock-based compensation cost for PSUs is recognized on a graded vesting basis in the consolidated statements of operations over the period during which the participant is required to perform services in exchange for the award, based on the fair value of the Company’s underlying common stock on the grant date and the number of PSUs expected to be earned over the service period. Each PSU grant will vest in annual tranches over a three-year service period. Total units earned for grants made in 2021 may vary between 0% and 250% of the units granted based on the attainment of company-specific performance targets during the related three-year period and continued service. The performance targets are established by the Compensation and Leadership Development Committee of the Board of Directors. All of the PSUs earned will be settled through the issuance of an equivalent number of shares of the Company’s common stock based on the payout level achieved.

As of June 30, 2021, $30.3 million of total unrecognized compensation cost related to PSUs was expected to be recognized over a weighted average period of approximately 2.1 years.

Employee Stock Purchase Plan

During the six months ended June 30, 2021, 60,064 shares of common stock were purchased under the ESPP.

As of June 30, 2021, there was approximately $0.4 million of unrecognized stock-based compensation cost related to the ESPP that is expected to be recognized over the remaining term of the offering period that began on February 1, 2021 and will end on July 31, 2021.

For the periods presented, the fair value of ESPP purchase rights was estimated using the Black-Scholes option-pricing model with the following assumptions:

	For the Three and Six Months Ended June 30,
	2021		2020
Fair market value of common stock	$	152.35	$	85.14
Volatility	34%		32%
Expected term	0.5 years		0.5 years
Expected dividend yield	n/a		n/a
Risk-free interest rate	0.08%		1.54%

12.	Net Loss Per Share Attributable to Common Shareholders

The Company calculates basic and diluted net loss per share attributable to common shareholders in conformity with the two-class method required for companies with participating securities.

The diluted net loss per share attributable to common shareholders is computed by giving effect to all potential dilutive common stock equivalents outstanding for the period. For purposes of this calculation, all common stock equivalents have been excluded from the calculation of diluted net loss per share attributable to common shareholders as their effect is antidilutive. As a result, basic and diluted net loss per common share was the same for each period presented.

The following table sets forth the computation of basic and diluted net loss per common share (in thousands, except per share data):

	For the Three Months Ended June 30,						For the Six Months Ended June 30,
	2021			2020			2021			2020
Numerator:
Net loss attributable to common shareholders	$	(27,650	)	$	(10,140	)	$	(57,638	)	$	(25,423	)
Denominator:
Weighted-average common shares outstanding-basic		86,090			78,924			85,765			78,414
Dilutive effect of share equivalents resulting from stock options, restricted stock units, performance share units, and ESPP shares		—			—			—			—

Net loss per common share, basic and diluted	$	(0.32	)	$	(0.13	)	$	(0.67	)	$	(0.32	)

The following weighted-average outstanding shares of common stock equivalents were excluded from the computation of diluted net loss per share attributable to common shareholders for the periods presented because the impact of including them would have been antidilutive (in thousands):

	For the Three Months Ended June 30,				For the Six Months Ended June 30,
	2021		2020		2021		2020
Options to purchase common shares		3,115		4,928		3,255		5,296

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

You should read the following discussion and analysis of our financial condition and results of operations together with the consolidated financial statements and related notes that are included elsewhere in this Quarterly Report on Form 10-Q and our 2020 Annual Report. This discussion contains forward-looking statements based upon current expectations that involve risks and uncertainties. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of various factors, including those set forth under “Risk Factors,” in Part II, Item 1A of this Quarterly Report on Form 10-Q and our 2020 Annual Report. See “Special Note Regarding Forward-Looking Statements” above.

Overview

We are a leading provider of tax compliance automation for businesses of all sizes. The Avalara Compliance Cloud includes calculation, returns, compliance document management, licensing and registration, fiscal representation, and tax content and insight solutions. We sell our solutions primarily on a subscription basis through our sales force, which focuses on selling to qualified leads provided by our marketing efforts and by partner referrals.

We focus on maintaining and expanding our partner network, which has been and will continue to be an essential part of our growth. We continue to increase the available number of partner integrations, which are designed to link the Avalara Compliance Cloud to a wide variety of business applications, including accounting, ERP, ecommerce, marketplace, POS, recurring billing, and CRM systems. Through marketing activities, we generate awareness from many businesses, both large and small, and enhance communications with our existing customers.

We make substantial investments by increasing headcount, investing in better software tools and technologies, and making strategic acquisitions to continuously improve the Avalara Compliance Cloud. With these investments, we will continue scaling our platform for continued growth, adding new features and functionality, supporting new products and content types, and improving the user experience. We expect to continue to make significant investments, both organically and through acquisitions, to gain new and relevant content, technology, and expertise that best serve the transaction tax needs of our customers.

Our business is impacted by the COVID-19 pandemic, which began during the first quarter of 2020 and has resulted in authorities implementing numerous preventative measures to contain or mitigate the extent of the impact, including travel bans and restrictions, limitations on business activity, quarantines, and shelter-in-place orders. These measures have caused, and may continue to cause, business slowdowns or shutdowns in affected areas. Almost all our employees currently work offsite and we expect these arrangements to continue for the majority of our workforce for the remainder of 2021. During the second quarter of 2021, some of the geographic areas we serve and work from began to loosen travel bans and restrictions, and, where it is safe to do so, we have resumed some in-person customer activities and events. However, as the COVID-19 pandemic continues to evolve, the extent and timing of the broader impact of the pandemic on our results of operations, overall financial performance and operating cash flows remains uncertain, including the impact on our future revenue growth, the timing of the resumption of normal operating expenses, and the extent to which any incremental expenses associated with the preventative and precautionary measures will be necessary.

Key Business Metrics

We regularly review several metrics to evaluate growth trends, measure our performance, formulate financial projections, and make strategic decisions. We discuss revenue and the components of operating results under the section of this report titled, “Key Components of Consolidated Statements of Operations,” and we discuss other key business metrics below.

	Jun 30, 2021			Mar 31, 2021			Dec 31, 2020			Sep 30, 2020			Jun 30, 2020			Mar 31, 2020			Dec 31, 2019 (3)			Sep 30, 2019 (3)

⁽¹⁾ During the second quarter of 2021, we revised the methodology for calculating core customers to include revenue from SST (see Number of Core Customers below for details). The table above includes the number of core customers using both the legacy and the revised methodologies.

⁽²⁾ During the second quarter of 2021, we revised the methodology for calculating net revenue retention rate to include revenue from SST. In addition, professional services revenue is no longer included in the revised calculation methodology, as these services tend to be more one-time in nature (see Net Revenue Retention Rate below for details). The table above includes the net revenue retention rate using both the legacy and the revised methodologies.

⁽³⁾ Net revenue retention rate - revised is not presented for the periods ended December 31, 2019 and September 30, 2019 due to certain prior period data needed to complete the calculation being unavailable.

Number of Core Customers

We believe core customers is a key indicator of our market penetration, growth, and potential future revenue. The small and mid-market customer segments have been and remain our primary target market segments for marketing and selling our solutions. We use core customers as a metric to focus our customer count reporting on our primary target market segment. During the second quarter of 2021, we revised our core customer calculation methodology to include revenue from our Streamlined Sales Tax solution (SST), which results in additional customers being included in reported core customers. Under the revised calculation methodology, we had as of June 30, 2021 and December 31, 2020, approximately 16,570 and 15,020 core customers, respectively.

We define a core customer as:

•

a unique account identifier in our primary U.S. billing systems (multiple companies or divisions within a single consolidated enterprise that each have a separate unique account identifier are each treated as separate customers);

•

that is active as of the measurement date; and

•

for which we have recognized, as of the measurement date, greater than $3,000 in total revenue during the previous 12 months.

Currently, our core customer count includes only customers with unique account identifiers in our primary U.S. billing systems and does not include customers that subscribe to our solutions through our international subsidiaries and certain legacy and acquired billing systems that have not yet been integrated into our primary U.S. billing systems (e.g., recent acquisitions and our lodging tax compliance solution). As we increase our international operations and sales in future periods, we may add customers billed from our international subsidiaries to the core customer metric.

As noted above, we revised our core customer calculation methodology during the second quarter of 2021. Under the prior methodology, revenue from SST was not included in our calculation of total revenue during the previous 12 months. This meant customers that would have otherwise met the definition of a core customer, with inclusion of attributable SST revenue, were excluded

from our core customer count as well as our disclosures on the percentage of total revenue attributable to core customers. The revised methodology for core customers includes revenue from SST.

We believe these changes improve the usefulness of this key business metric, which is to measure both the growth of existing customers into core customers and the acquisition of new customers of a certain size.

We also have a substantial number of customers of various sizes that do not meet the revenue threshold to be considered a core customer. Many of these customers are in the emerging and small business segment of the marketplace, which represents strategic value and a growth opportunity for us. Customers who do not meet the revenue threshold to be considered a core customer provide us with market share and awareness, and we anticipate that some may grow into core customers. In addition, we have numerous enterprise-level customers that only utilize our services for small segments of their business, providing opportunities over time for us to extend our relationship and make them core customers.

In addition to customers with whom we have a direct relationship, some of our customers are business application publishers (including ecommerce platforms) that include automated tax determination powered by Avalara. While those platform providers may be core customers to Avalara, their end-user customers generally are not.

Net Revenue Retention Rate

We believe that our net revenue retention rate provides insight into our ability to retain and grow revenue from our customers, as well as their potential long-term value to us. We also believe it reflects the stability of our revenue base, which is one of our core competitive strengths. We calculate our net revenue retention rate by dividing (a) total subscription and returns revenue in the current quarter from any billing accounts that generated revenue during the corresponding quarter of the prior year by (b) total subscription and returns revenue in such corresponding quarter from those same billing accounts. This calculation includes changes during the period for such billing accounts, such as additional solutions purchased, changes in pricing and transaction volume, and terminations, but does not reflect revenue for new billing accounts added during the one-year period.

Currently, our net revenue retention rate includes only customers with unique account identifiers in our primary U.S. billing systems and does not include customers who subscribe to our solutions through our international subsidiaries or certain legacy billing systems that have not been integrated into our primary U.S. billing systems.

During the second quarter of 2021, we revised our net revenue retention rate calculation methodology. Under the prior methodology, revenue from our SST solution was not included in net revenue retention rate. This means that revenue expansion from existing customers adopting our SST solution was not included, while revenue contraction from customers replacing one or more of Avalara’s other solutions with SST was included. The revised calculation methodology for net revenue retention rate includes revenue from SST. In addition, professional services revenue is no longer included in the revised calculation methodology, as these services tend to be more one-time in nature. Under the revised calculation methodology, our net revenue retention rate was 116% for the quarter ended June 30, 2021 and on average has been 115% over the last four quarters ended June 30, 2021. Under the legacy calculation methodology, our net revenue retention rate was 110% for the quarter ended June 30, 2021 and on average has been 107% over the last four quarters ended June 30, 2021.

Key Components of Consolidated Statements of Operations

Revenue

We generate revenue from two primary sources: (1) subscription and returns; and (2) professional services. Subscription and returns revenue are driven primarily by the acquisition of customers, customer renewals, and additional service offerings purchased by existing customers. Revenue from subscription and returns comprised approximately 90% of our revenue for the six months ended June 30, 2021 and 94% of our revenue for the six months ended June 30, 2020.

Subscription and Returns Revenue. Subscription and returns revenue primarily consist of fees paid by customers to use our solutions. Subscription plan customers select a price plan that includes an allotted maximum number of transactions over the subscription term. Unused transactions are not carried over to the customer’s next subscription term, and our customers are not entitled to any refund of fees paid or relief from fees due if they do not use the allotted number of transactions. If a subscription plan customer exceeds the selected maximum transaction level, we will generally upgrade the customer to a higher tier or, in some cases, charge overage fees on a per transaction or return basis. Customers purchase tax return preparation on a subscription basis for an allotted number of returns. Fees paid for subscription services to tax content vary depending on the volume of tax information accessible to the customer.

Our standard subscription contracts are generally non-cancelable after the first 60 days of the contract term. Cancellations under our standard subscription contracts are not material, and do not have a significant impact on revenue recognized. We generally invoice our subscription customers for the initial term at contract signing and upon renewal. Our initial terms generally range from 12 to 18 months, and renewal periods are typically one year. Amounts that have been invoiced are initially recorded as deferred revenue or contract liabilities. Subscription revenue is recognized on a straight-line basis over the service term of the arrangement beginning on the date that our solution is made available to the customer and ending at the expiration of the subscription term.

Currently a small component of our total revenue, we offer SST services to businesses that are registered to participate in the program. We earn a fee (SST revenue) from participating state and local governments based on a percentage of the sales tax reported and paid, and as a result, we generally provide SST services at no cost to the seller. During the first quarter of 2021, we renewed our agreement with the SST Governing Board to provide SST services at a lower percentage rate than we previously earned.

Subscription and returns revenue also include interest income generated on funds held for customers. In order to provide tax remittance services to customers, we hold funds from customers in advance of remittance to tax authorities. These funds are held in trust accounts at FDIC-insured institutions. Prior to remittance, we earn interest on these funds.

Professional Services. We generate professional services revenue from providing tax analysis and services, including tax registrations, voluntary disclosure agreements, nexus studies, and back filing services. We also provide configurations, data migrations, integration, and training, for our subscriptions and returns products. Our 2020 acquisitions of TTR and Business Licenses expanded the scope of professional services we offer to include business licenses and registration services and tax refund claims and recovery assistance. We bill for service arrangements on a fixed fee, milestone, or time and materials basis, and we recognize the transaction price allocated to professional services performance obligations as revenue as services are performed and are collectable under the terms of the associated contracts.

Costs and Expenses

Cost of Revenue. Cost of revenue consists of costs related to providing the Avalara Compliance Cloud and supporting our customers and includes employee-related expenses, including salaries, benefits, bonuses, and stock-based compensation and the amortization of capitalized software development costs. In addition, cost of revenue includes direct costs associated with information technology, such as data center and software hosting costs, tax content maintenance, and certain services provided by third parties. Cost of revenue also includes allocated costs for certain information technology and facility expenses, along with depreciation of equipment and amortization of intangibles such as acquired technology from acquisitions. We plan to continue to significantly expand our infrastructure and personnel to support our future growth, including through acquisitions, which we expect to result in higher cost of revenue in absolute dollars.

Research and Development. Research and development expenses consist primarily of employee-related expenses for our research and development staff, including salaries, benefits, bonuses, and stock-based compensation, and the cost of third-party developers. Research and development costs, other than software development expenses qualifying for capitalization, are expensed as incurred. Capitalized software development costs, which consist primarily of employee-related costs, are amortized as cost of subscription and returns revenue. Research and development expenses also include allocated costs for certain information technology and facility expenses, along with depreciation of equipment.

We devote substantial resources to enhancing and maintaining the Avalara Compliance Cloud, developing new and enhancing existing solutions, conducting quality assurance testing, and improving our core technology. We expect research and development expenses to increase in absolute dollars.

Sales and Marketing. Sales and marketing expenses consist primarily of employee-related expenses for our sales and marketing staff, including salaries, benefits, bonuses, sales commissions, and stock-based compensation, integration and referral partner commissions, costs of marketing and promotional events, corporate communications, online marketing, solution marketing, and other brand-building activities. As a result of the current COVID-19 pandemic, we suspended in-person promotional and customer events and converted many of these activities to virtual events, which temporarily reduced these types of marketing expenses. We have begun to resume limited in-person marketing activities in the second half of 2021 where it is safe to do so. Sales and marketing expenses include allocated costs for certain information technology and facility expenses, along with depreciation of equipment and amortization of intangibles such as customer relationships, customer lists, and backlog from acquisitions.

We defer the portion of sales commissions that is considered a cost of obtaining a new contract with a customer in accordance with the revenue recognition standard and amortize these deferred costs over the period of benefit, currently six years. We expense the remaining sales commissions as incurred. Sales commissions are earned when a sales order is completed. For most sales orders,

deferred revenue is recorded when a sales order is invoiced, and the related revenue is recognized ratably over the subscription term. The rates at which sales commissions are earned varies depending on a variety of factors, including the nature of the sale (new, renewal, or add-on service offering), the type of service or solution sold, and the sales channel. At the beginning of each year, we set group and individual sales targets and update targets during the year as appropriate. Sales commissions are generally earned based on achievement against these targets.

We defer the portion of partner commissions costs that are considered a cost of obtaining a contract with a customer in accordance with the revenue recognition standard and amortize these deferred costs over the period of benefit. The period of benefit is separately determined for each partner and is either six years or corresponds with the contract term. We expense the remaining partner commissions costs as incurred. Our partner commission expense has historically been, and will continue to be, impacted by many factors, including the proportion of new and renewal sales, the nature of the partner relationship, and the sales mix among partners during the period. In general, integration partners are paid a higher commission for the initial sale to a new customer and a lower commission for renewal sales. Additionally, we have several types of partners (e.g., integration and referral) that each earn different commission rates.

We intend to continue to invest in sales and marketing and expect spending in these areas to increase in absolute dollars as we continue to expand our business. We expect sales and marketing expenses to continue to be among the most significant components of our operating expenses.

General and Administrative. General and administrative expenses consist primarily of employee-related expenses for administrative, finance, information technology, legal, and human resources staff, including salaries, benefits, bonuses, and stock-based compensation, professional fees, insurance premiums, and other corporate expenses that are not allocated to the above expense categories. General and administrative expenses include amortization of intangibles such as tradenames and noncompetition agreements from acquisitions.

We expect our general and administrative expenses to increase in absolute dollars as we continue to expand our operations, hire and train additional personnel, evaluate and integrate acquisitions, and incur costs as a public company. Specifically, we expect to continue to incur increased expenses related to accounting, tax and auditing activities, legal, insurance, acquisition evaluation and execution, SEC compliance, and internal control compliance.

Total Other (Income) Expense, Net

Total other (income) expense, net consists of interest income on cash and cash equivalents, quarterly remeasurement of earnout liabilities for acquisitions accounted for as business combinations, foreign currency gains and losses, and other nonoperating gains and losses.

Results of Operations

The following sets forth our results of operations for the periods presented and as a percentage of our total revenue for those periods. The period-to-period comparison of financial results is not necessarily indicative of financial results to be achieved in future periods.

The comparability of periods covered by our financial statements is impacted by recent acquisitions. In the fourth quarter of 2020, we acquired the outstanding equity of TTR, substantially all the assets of Business Licenses, and the outstanding equity of Impendulo. During the second quarter of 2021, we acquired substantially all the assets of Davo and the outstanding equity of Inposia (See Note 5 in the Notes to Consolidated Financial Statements).

Professional services		16,625		7,968		8,657		109	%
Total revenue	$	169,067	$	116,487	$	52,580		45	%

Total revenue for the three months ended June 30, 2021 increased by $52.6 million, or 45%, compared to the three months ended June 30, 2020. Subscription and returns revenue for the three months ended June 30, 2021 increased by $43.9 million, or 40%, compared to the three months ended June 30, 2020. Professional services revenue for the three months ended June 30, 2021 increased by $8.7 million, or 109%, compared to the three months ended June 30, 2020.

Growth in total revenue was due primarily to increased demand for our services from new and existing customers and recent acquisitions. The increase in total revenue for the three months ended June 30, 2021 compared to the same period in 2020, was due primarily to $15.7 million from new U.S. customers, $15.4 million from recent acquisitions, $11.6 million from existing U.S. customers, $4.9 million from SST revenue growth, and $4.8 million from revenue growth in our international operations. Excluding recent acquisitions, total revenue for the three months ended June 30, 2021 increased by $37.1 million, or 32%, compared to the three months ended June 30, 2020. Of the growth from recent acquisitions, $8.3 million was generated from subscriptions and returns and $7.1 million from professional services. Despite lower transaction rates for the three months ended June 30, 2021, SST revenue increased from the prior period due to higher transaction volume.

Total cost of revenue	$	48,675	$	33,330	$	15,345		46	%

Cost of revenue for the three months ended June 30, 2021 increased by $15.3 million, or 46%, compared to the three months ended June 30, 2020. The increase in cost of revenue was due primarily to an increase of $10.7 million in employee-related costs from higher headcount, an increase of $1.5 million in software hosting costs, an increase of $1.3 million in amortization expense, an increase of $1.3 million in allocated overhead cost, and an increase of $0.5 million in depreciation expense.

Cost of revenue headcount increased approximately 48% from the second quarter of 2020 to the second quarter of 2021. Excluding the impact of recent acquisitions, cost of revenue headcount increased approximately 29% due to our continued growth to support our solutions. Employee-related costs increased due primarily to a $7.5 million increase in salaries and benefits (including $4.5 million from recent acquisitions), $1.4 million increase in compensation expense related to our bonus plans, a $1.0 million increase in stock-based compensation expense, and a $0.8 million increase in contract and temporary employee costs.

Software hosting costs increased due primarily to higher transaction volumes and incremental investment in data management and reporting tools. Amortization expense increased due primarily to acquired intangible assets from our recent acquisitions. Allocated overhead consists primarily of facility expenses and shared information technology expenses. Shared information technology expenses are higher compared to the prior period due primarily to higher headcount throughout our operations. Depreciation expense increased due primarily to an increase in capitalized software costs for projects placed into service in 2020.

Research and Development

	For the Three Months Ended June 30,				Change
	2021		2020		Amount		Percentage
	(dollars in thousands)
Research and development	$	40,111	$	26,844	$	13,267		49	%

Research and development expenses for the three months ended June 30, 2021 increased by $13.3 million, or 49%, compared to the three months ended June 30, 2020. The increase was due primarily to an increase of $11.1 million in employee-related costs from higher headcount, an increase of $1.3 million in third-party purchased software costs, and an increase of $0.7 million in outside professional services expense.

Research and development headcount increased approximately 41% from the second quarter of 2020 to the second quarter of 2021. Excluding the impact of recent acquisitions, research and development headcount increased approximately 31%. Employee-related costs increased due primarily to a $6.0 million increase in salaries and benefits (including $1.9 million from recent acquisitions), a $3.0 million increase in stock-based compensation expense, including $0.8 million of new PSU grants for executives, and a $2.1 million increase in compensation expense related to our bonus plans.

Software costs increased due primarily to additional investment in information technology security and reporting tools for product analysis, development, and testing activities. Outside professional services expense increased due primarily to an increase in third-party information technology security services and third-party developer services for product integrations maintenance and support.

Sales and Marketing

	For the Three Months Ended June 30,				Change
	2021		2020		Amount		Percentage
	(dollars in thousands)
Sales and marketing	$	71,897	$	46,040	$	25,857		56	%

Sales and marketing expenses for the three months ended June 30, 2021 increased by $25.9 million, or 56%, compared to the three months ended June 30, 2020. The increase was due primarily to an increase of $14.1 million in employee-related costs, an increase of $4.8 million in marketing campaign expenses, an increase of $2.6 million for partner commission expense, an increase of $2.4 million in amortization expense, an increase of $1.2 million in allocated overhead cost, and an increase of $0.4 million in third-party purchased software costs.

Marketing campaign expenses increased due primarily to increased spending on market research, brand awareness, online advertising and outbound direct mail advertising. Partner commission expense increased due primarily to higher revenues. Amortization expense increased due primarily to acquired intangible assets from our recent acquisitions. Third-party purchased software costs increased due primarily to additional investment in lead generation technology.

	2021		2020		Amount		Percentage
	(dollars in thousands)
General and administrative	$	35,244	$	20,322	$	14,922		73	%

General and administrative expenses for the three months ended June 30, 2021 increased by $14.9 million, or 73%, compared to the three months ended June 30, 2020. The increase was due primarily to an increase of $9.5 million in employee-related costs, an increase of $3.0 million in outside professional services expense, an increase of $0.9 million in amortization expense, an increase of $0.5 million in third-party purchased software costs, and an increase of $0.5 million in insurance, partially offset by a decrease of $0.7 million in non-income tax expense.

General and administrative headcount increased approximately 36% from the second quarter of 2020 to the second quarter of 2021. Excluding the impact of recent acquisitions, general and administrative headcount increased approximately 29%. Employee-related costs increased due primarily to a $2.8 million increase in salaries and benefits (including $0.9 million from recent acquisitions), a $4.8 million increase in stock-based compensation expense, including $3.4 million of PSU grants for executives, $1.5 million increase in compensation expense related to our bonus plans, and a $0.4 million increase in contract and temporary employee costs.

Outside professional services expenses increased due primarily to increased investment in employee engagement, principally satisfaction surveys, recruiting services, and training programs and, to a lesser extent, acquisition related costs. Amortization increased due to acquired intangibles from our recent acquisitions. Software costs increased due primarily to an increase in the number of licenses purchased and higher subscription fees for key financial and human resources information system applications. Insurance expenses increased due to higher insurance premiums in the current year. Non-income tax expense decreased due primarily to lower state indirect taxes.

Total Other (Income) Expense, Net

Other (income) expense, net		961			122			839
Total other (income) expense, net	$	938		$	(46	)	$	984

Total other (income) expense, net for the three months ended June 30, 2021 was $0.9 million of expense compared to approximately breakeven for the three months ended June 30, 2020. Interest income decreased due primarily to a decline in the interest rate earned on our cash and cash equivalents. Other (income) expense, net was $1.0 million other expense for the three months ended June 30, 2021 compared to $0.1 million other expense for the three months ended June 30, 2020, due primarily to changes to our earnout liabilities. We estimate the fair value of earnout liabilities related to business combinations quarterly. During the three months ended June 30, 2021, the adjustments to fair value increased the carrying value of the earnout liability for our acquisitions of TTR and Business Licenses, resulting in other expense of $1.2 million. During the three months ended June 30, 2020, the adjustments to fair value increased the carrying value of the earnout liability for our acquisition of Portway, resulting in other expense of $0.2 million.

(Benefit from) Provision for Income Taxes

	2021			2020		Amount
	(dollars in thousands)
(Benefit from) provision for income taxes	$	(148	)	$	137	$	(285	)

The benefit from income taxes for the three months ended June 30, 2021 was $0.1 million compared to a provision for income taxes of $0.1 million for the three months ended June 30, 2020. The effective income tax rate was 0.5% for the three months ended June 30, 2021 compared to (1.4)% for the three months ended June 30, 2020. The effective tax rate in both quarters differ from the U.S. Federal statutory rate due primarily to providing a valuation allowance on deferred tax assets. The decrease in expense and increase in effective rate is due primarily to 2021 tax benefits resulting from the Inposia acquisition (see Note 5 in the Notes to Consolidated Financial Statements).

We have assessed our ability to realize our deferred tax assets and have recorded a valuation allowance against such assets to the extent that, based on the weight of all available evidence, it is more likely than not that all or a portion of the deferred tax assets will not be realized. In assessing the likelihood of future realization of our deferred tax assets, we placed significant weight on our history of generating tax losses in the U.S., U.K, and Brazil, including in the first half of 2021. As a result, we have a full valuation allowance against our net deferred tax assets, including net operating loss carryforwards, and research and development tax credits. We expect to maintain a full valuation allowance for the foreseeable future.

Total revenue	$	322,668	$	227,930	$	94,738		42	%

Total revenue for the six months ended June 30, 2021 increased by $94.7 million or 42%, compared to the six months ended June 30, 2020. Subscription and returns revenue for the six months ended June 30, 2021 increased by $77.7 million, or 36%, compared to the six months ended June 30, 2020. Professional services revenue for the six months ended June 30, 2021 increased by $17.0 million, or 123%, compared to the six months ended June 30, 2020.

Growth in total revenue was due primarily to increased demand for our services from new and existing customers and recent acquisitions. The increase in total revenue for the six months ended June 30, 2021 compared to the same period in 2020, was due primarily to $26.7 million from new U.S. customers, $26.0 million from recent acquisitions, $23.3 million from existing U.S. customers, $10.9 million from SST revenue growth, and $8.2 million attributable to revenue growth in our international operations. Excluding recent acquisitions, total revenue for the six months ended June 30, 2021 increased by $68.9 million, or 30%, compared to the six months ended June 30, 2020. Of the growth from recent acquisitions, $14.0 million was generated from subscriptions and returns and $12.0 million from professional services. Despite lower transaction rates for the six months ended June 30, 2021, SST revenue increased from the prior period due to higher transaction volume.

Total cost of revenue	$	93,346	$	67,584	$	25,762		38	%

Cost of revenue for the six months ended June 30, 2021 increased by $25.8 million, or 38%, compared to the six months ended June 30, 2020. The increase in cost of revenue in absolute dollars was due primarily to an increase of $20.2 million in employee-related costs from higher headcount, an increase of $2.1 million in amortization expense, an increase of $1.9 million in allocated overhead cost, an increase of $0.9 million in depreciation expense, and an increase of $0.7 million in software hosting costs.

Cost of revenue headcount increased approximately 48% from the second quarter of 2020 to the second quarter of 2021. Excluding the impact of recent acquisitions, cost of revenue headcount increased approximately 29% due to continued growth to support our solutions. Employee-related costs increased due primarily to a $14.9 million increase in salaries and benefits (including $8.0 million from recent acquisitions), $2.4 million increase in compensation expense related to our bonus plans, a $2.0 million increase in stock-based compensation expense, and a $1.4 million increase in contract and temporary employee costs.

Amortization expense increased due primarily to acquired intangible assets from our recent acquisitions. Allocated overhead consists primarily of facility expenses and shared information technology expenses. Shared information technology expenses are higher compared to the prior period due primarily to higher headcount throughout our operations. Depreciation expense increased due primarily to an increase in capitalized software costs for projects placed into service in 2020. Software hosting costs increased due primarily to higher transaction volumes and incremental investment in data management and reporting tools.

Total gross profit for the six months ended June 30, 2021 increased $69.0 million, or 43% compared to the six months ended June 30, 2020. Total gross margin was 71% for the six months ended June 30, 2021 compared to 70% for the same period of 2020. This increase in gross margin was due primarily to improved service delivery and efficiency in U.S. professional services.

Research and Development

	For the Six Months Ended June 30,				Change
	2021		2020		Amount		Percentage
	(dollars in thousands)
Research and development	$	79,267	$	52,691	$	26,576		50	%

Research and development expenses for the six months ended June 30, 2021 increased by $26.6 million, or 50%, compared to the six months ended June 30, 2020. The increase was due primarily to an increase of $22.3 million in employee-related costs from higher headcount, an increase of $3.4 million in third-party purchased software costs, and an increase of $0.9 million in outside professional services expense.

Research and development headcount increased approximately 41% from the second quarter of 2020 to the second quarter of 2021. Excluding the impact of recent acquisitions, research and development headcount increased approximately 31%. Employee-related costs increased due primarily to a $13.0 million increase in salaries and benefits (including $2.9 million from recent acquisitions), a $5.9 million increase in stock-based compensation expense, including $1.3 million of PSU grants for executives, and a $3.7 million increase in compensation expense related to our bonus plans.

Sales and Marketing

	For the Six Months Ended June 30,				Change
	2021		2020		Amount		Percentage
	(dollars in thousands)
Sales and marketing	$	136,201	$	95,674	$	40,527		42	%

Sales and marketing expenses for the six months ended June 30, 2021 increased by $40.5 million, or 42%, compared to the six months ended June 30, 2020. The increase was due primarily to an increase of $22.9 million in employee-related costs, an increase of $6.6 million in marketing campaign expenses, an increase of $4.1 million for partner commission expense, an increase of $3.3 million in amortization expense, an increase of $1.9 million in allocated overhead cost, an increase of $1.0 million in outside professional services expense, and an increase of $0.8 million in third-party purchased software costs.

Sales and marketing headcount increased approximately 41% from the second quarter of 2020 to the second quarter of 2021. Excluding the impact of recent acquisitions, sales and marketing headcount increased approximately 33%. Employee-related costs increased due primarily to a $13.8 million increase in salaries and benefits (including $2.7 million from recent acquisitions), a $3.9 million increase in sales commission expense, a $3.7 million increase in stock-based compensation expense, a $2.4 million increase in contract and temporary employee costs, and a $2.0 million increase in compensation expense related to our bonus plans, partially offset by a $2.9 million decrease in travel costs. Travel costs decreased due primarily to cancelling all in-person customer activities and events beginning in March of 2020 because of the COVID-19 pandemic. During the second half of 2021, we expect to gradually resume in-person customer activities and events, where it is safe to do so, which will increase travel costs that were suspended during the COVID-19 pandemic.

Marketing campaign expenses increased due primarily to increased spending on market research, brand awareness, online advertising, and outbound direct mail advertising. Partner commission expense increased due primarily to higher revenues. Amortization expense increased due primarily to acquired intangible assets from our recent acquisitions. Outside professional services expenses increased due primarily to increased third-party consulting services to improve the customer experience during onboarding, to develop prospective customer data, to produce brand recognition and positioning studies, and services to integrate websites of recent acquisitions. Third-party purchased software costs increased due primarily to increased investment in lead generation technology.

General and Administrative

	For the Six Months Ended June 30,				Change
	2021		2020		Amount		Percentage
	(dollars in thousands)
General and administrative	$	66,095	$	41,710	$	24,385		58	%

General and administrative expenses for the six months ended June 30, 2021 increased by $24.4 million, or 58%, compared to the six months ended June 30, 2020. The increase was due primarily to an increase of $17.2 million in employee-related costs, an increase of $3.6 million in outside professional services expense, an increase of $1.7 million in amortization expense, and a $0.9 million increase in insurance, partially offset by a $1.2 million decrease in non-income tax expense and a $0.7 million expense to settle a contract dispute in the prior year period.

General and administrative headcount increased approximately 36% from the second quarter of 2020 to the second quarter of 2021. Excluding the impact of recent acquisitions, general and administrative headcount increased approximately 29%. Employee-related costs increased due primarily to a $6.3 million increase in salaries and benefits (including $1.8 million from recent acquisitions), a $8.5 million increase in stock-based compensation expense, including $5.7 million of PSU grants for executives, a $2.5 million increase in compensation expense related to our bonus plans, and a $0.6 million increase in contract and temporary employee costs, partially offset by a $0.6 million decrease in travel costs.

Outside professional services expenses increased due primarily to increased investment in employee engagement, principally satisfaction surveys, support services, recruiting services, training programs and, to a lesser extent, acquisition related costs. Amortization increased due to acquired intangibles from our recent acquisitions. Insurance expenses increased due to higher insurance premiums in the current year. Non-income tax expense decreased due primarily to lower state and foreign indirect taxes. During the six months ended June 30, 2020, we agreed to settle a contract dispute, with no comparable costs in the current period.

Total Other (Income) Expense, Net

	For the Six Months Ended June 30,						Change
	2021			2020			Amount
	(dollars in thousands)
Other (income) expense, net
Interest income	$	(47	)	$	(1,610	)	$	1,563
Other (income) expense, net		3,235			(3,250	)		6,485
Total other (income) expense, net	$	3,188		$	(4,860	)	$	8,048

Total other income (expense), net for the six months ended June 30, 2021 was $3.2 million of expense compared to $4.9 million of income for the six months ended June 30, 2020. Interest income decreased due to a decline in the interest rate earned on our cash and cash equivalents. Other income (expense), net was $3.2 million of expense for the six months ended June 30, 2021 compared to $3.3 million of income for the six months ended June 30, 2020, due primarily to changes to our earnout liabilities. We estimate the fair value of earnout liabilities related to business combinations quarterly. During the first half of 2021, the adjustments to fair value increased the carrying value of the earnout liability for our acquisitions of TTR and Business Licenses, resulting in other expense of $2.5 million. During the first half of 2020, the adjustments to fair value decreased the carrying value of the earnout liability for our acquisition of Portway, resulting in other income of $2.3 million.

Provision for Income Taxes

	For the Six Months Ended June 30,				Change
	2021		2020		Amount
	(dollars in thousands)
Provision for income taxes	$	2,209	$	554	$	1,655

The provision for income taxes for the six months ended June 30, 2021 was $2.2 million compared to a provision for income taxes of $0.6 million for the six months ended June 30, 2020. The effective income tax rate was (4.0)% for the six months ended June 30, 2021 compared to (2.2)% for the six months ended June 30, 2020. The effective tax rate in both quarters differs from the U.S. Federal statutory rate due primarily to providing a valuation allowance on deferred tax assets. The increase in tax expense and increase in effective rate is due primarily to measurement period adjustments related to the 2020 acquisition of TTR recorded during the first quarter of 2021 (see Note 5 in the Notes to Consolidated Financial Statements).

Liquidity and Capital Resources

We require cash to fund our operations, including outlays for infrastructure growth, acquisitions, geographic expansion, expanding our sales and marketing activities, research and development efforts, and working capital for our growth. We have financed our operations primarily through cash received from customers for our solutions and public offerings of our common stock. As of June 30, 2021, we had $639.5 million of cash and cash equivalents, most of which was held in money market accounts.

Borrowings

As of June 30, 2021, we had no credit facilities or borrowings outstanding.

Future Cash Requirements

As of June 30, 2021, our cash and cash equivalents included proceeds from our previous public offerings of common stock. We intend to continue to increase our operating expenses and capital expenditures to support the growth in our business and operations. We expect to also use our cash and cash equivalents to acquire complementary businesses, products, services, technologies, or other assets. We believe that our existing cash and cash equivalents of $639.5 million as of June 30, 2021 will be sufficient to meet our anticipated cash needs for at least the next 12 months. Our financial position and liquidity are, and will be, influenced by a variety of

factors, including our growth rate, the timing and extent of spending to support research and development efforts, the continued expansion of sales and marketing spending, the introduction of new and enhanced solutions, the cash paid for any acquisitions, and the continued market acceptance of our solutions.

The following table shows our cash flows from operating activities, investing activities, and financing activities for the stated periods:

	For the Six Months Ended June 30,
	2021			2020
	(in thousands)
Cash provided by (used in):
Operating Activities	$	(2,697	)	$	(16,974	)
Investing Activities		(34,532	)		(3,556	)
Financing Activities		(1,331	)		25,333

Operating Activities

Our largest source of operating cash is cash collections from our customers for subscriptions and returns services. Our primary uses of cash from operating activities are for employee-related expenditures, commissions paid to our partners, marketing expenses, technology costs such as software hosting costs, and facilities expenses. Cash used in operating activities is comprised of our net loss adjusted for certain non-cash items, including stock-based compensation, depreciation and amortization, other non-cash income and expense items, and net changes in operating assets and liabilities.

For the six months ended June 30, 2021, net cash used in operating activities was $2.7 million compared to net cash used of $17.0 million for the six months ended June 30, 2020. The decrease in cash used in operations of $14.3 million was due primarily to an increase in cash collected from customers as demand for our subscription services continued to grow and to extended payment terms in the prior year that were provided to some of our customers at the onset of the COVID-19 pandemic.

Investing Activities

Our investing activities primarily include cash outflows related to purchases of property and equipment, additions of capitalized software, and from time to-time, cash paid for asset and business acquisitions.

For the six months ended June 30, 2021, cash used in investing activities was $34.5 million, compared to cash used of $3.6 million for the six months ended June 30, 2020. The increase in cash used in investing activities of $31.0 million was due primarily to an increase in cash paid for acquisitions of businesses of $24.0 million, an increase in additions of capitalized software of $4.4 million, an increase in cash paid for acquired intangible assets of $1.5 million, and an increase in capital expenditures of $1.1 million. In the first half of 2021, we acquired Inposia and Davo for total cash consideration, net of cash acquired of $22.1 million and paid $1.9 million of additional purchase price to finalize net working capital and other adjustments related to the 2020 acquisitions of TTR and Impendulo.

Financing Activities

Our financing activities primarily include cash inflows and outflows from issuance and repurchases of capital stock, our employee stock purchase plan, deferred cash payments made in connections with acquisitions of businesses, and changes in customer fund obligations.

For the six months ended June 30, 2021, cash used in financing activities was $1.3 million compared to cash provided of $25.3 million for the six months ended June 30, 2020. This increase in cash used in financing activities of $26.6 million was due primarily to $20.8 million cash paid in the six months ended June 30, 2021 for purchase price holdbacks related to the 2020 acquisition of TTR and the 2019 acquisition of Portway International Inc., a $15.2 million decrease in cash proceeds from exercise of stock options, and a $0.6 million increase in deferred cash payments related to asset acquisition earnouts. These cash outflows were partially offset by a $4.9 million increase in net cash flows related to customer fund obligations in the first half of 2021 compared to the prior period, a $3.8 million decrease in deferred cash payments related to business combination earnouts, and a $1.4 million increase in cash proceeds from common stock purchased under our employee stock purchase plan.

Funds Held from Customers and Customer Fund Obligations

We maintain trust accounts with FDIC-insured financial institutions, which allows our customers to outsource their tax remittance functions to us. We have legal ownership over the accounts utilized for this purpose. Funds held from customers are not commingled with our operating funds but are typically deposited with funds also held on behalf of our other customers. Funds held from customers

represents restricted cash equivalents that, based upon our intent, are restricted solely for satisfying the obligations to remit funds relating to our tax remittance services. Changes in customer funds assets account that relate to activities paying for the trust operations, such as banking fees, are included as cash flows from operating activities.

Customer funds obligations represent our contractual obligations to remit collected funds to satisfy customer tax payments. Customer funds obligations are reported as a current liability on the consolidated balance sheets, as the obligations are expected to be settled within one year. Changes in customer funds obligations liability are presented as cash flows from financing activities.

Contractual Obligations and Commitments

During the first half of 2021, our purchase commitments increased approximately $51.2 million compared to December 31, 2020, primarily related to software hosting and software license subscriptions that extend up to three years beyond June 30, 2021. There were no other material changes to our contractual obligations as of June 30, 2021 compared to December 31, 2020.

Use and Reconciliation of Non-GAAP Financial Measures

In addition to our results determined in accordance with GAAP, we have disclosed non-GAAP cost of revenue, non-GAAP gross profit, non-GAAP gross margin, non-GAAP research and development expense, non-GAAP sales and marketing expense, non-GAAP general and administrative expense, non-GAAP operating income (loss), non-GAAP net income (loss), free cash flow, and calculated billings, which are all non-GAAP financial measures. We have provided tabular reconciliations of each non-GAAP financial measure to its most directly comparable GAAP financial measure.

•

We calculate non-GAAP cost of revenue, non-GAAP research and development expense, non-GAAP sales and marketing expense, and non-GAAP general and administrative expense as GAAP cost of revenue, GAAP research and development expense, GAAP sales and marketing expense, and GAAP general and administrative expense before stock-based compensation expense and the amortization of acquired intangible assets included in each of the expense categories.

•

We calculate non-GAAP gross profit as GAAP gross profit before the stock-based compensation expense and amortization of acquired intangibles included in cost of revenue. We calculate non-GAAP gross margin as GAAP gross margin before the impact of stock-based compensation expense and the amortization of acquired intangibles included in cost of revenue as a percentage of revenue.

•

We calculate non-GAAP operating income (loss) as GAAP operating loss before stock-based compensation expense, amortization of acquired intangibles, and goodwill impairments. We calculate non-GAAP net income (loss) as GAAP net loss before stock-based compensation expense, amortization of acquired intangibles, and goodwill impairments.

•

We define free cash flow as net cash used in operating activities less cash used for the purchases of property and equipment and capitalized software development costs.

•

We define calculated billings as total revenue plus the changes in deferred revenue and contract liabilities in the period, excluding the acquisition date impact of deferred revenue and contract liabilities assumed in a business combination. Because we generally recognize subscription revenue ratably over the subscription term, calculated billings can be used to measure our subscription sales activity for a particular period, to compare subscription sales activity across particular periods, and as a potential indicator of future subscription revenue, the actual timing of which will be affected by several factors, including subscription start date and duration.

Management uses these non-GAAP financial measures to understand and compare operating results across accounting periods, for internal budgeting and forecasting purposes, and to evaluate financial performance and liquidity. We believe that non-GAAP financial measures provide useful information to investors and others in understanding and evaluating our results, prospects, and liquidity period-over-period without the impact of certain items that do not directly correlate to our performance and that may vary significantly from period to period for reasons unrelated to our operating performance, as well as when comparing our financial results to those of other companies.

Our definitions of these non-GAAP financial measures may differ from the definitions used by other companies and therefore comparability may be limited. In addition, other companies may not publish these or similar metrics. Thus, our non-GAAP financial measures should be considered in addition to, not as a substitute for, or in isolation from, measures prepared in accordance with GAAP.

We encourage investors and others to review our financial information in its entirety, not to rely on any single financial measure and to view non-GAAP financial measures in conjunction with the related GAAP financial measure.

The following schedules reflect our non-GAAP financial measures and reconcile our non-GAAP financial measures to the related GAAP financial measures:

Critical Accounting Policies and Estimates

There have been no material updates or changes to our critical accounting policies and estimates compared to the critical accounting policies and estimates described in our 2020 Annual Report.

Recent Accounting Pronouncements

For further information on recent accounting pronouncements, refer to Note 2 in the consolidated financial statements contained within this Quarterly Report on Form 10-Q.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

Interest Rate Risk

We had cash and cash equivalents of $639.5 million and $673.6 million as of June 30, 2021 and December 31, 2020, respectively. We maintain our cash and cash equivalents in deposit accounts and money market funds with financial institutions. Due to the short-term nature of these instruments, we believe that we do not have any material exposure to changes in the fair value of our investment portfolio as a result of changes in interest rates. Declines in interest rates, however, would reduce future interest income.

At June 30, 2021, we had no credit facilities in place and had no borrowings outstanding. Any debt we incur in the future may bear interest at variable rates and may expose us to risk related to changes in interest rates.

Foreign Currency Exchange Risk

Our revenue and expenses are primarily denominated in U.S. dollars. For our foreign operations, the majority of our revenues and expenses are denominated in other currencies, such as the Brazilian Real, British Pound, Euro, and Indian Rupee. Decreases in the relative value of the U.S. dollar as compared to these currencies may negatively affect our revenue and other operating results as expressed in U.S. dollars. For the three and six months ended June 30, 2021 and 2020, approximately 8% and 6% of our revenues, respectively, were generated in currencies other than U.S. dollars. We have experienced and will continue to experience fluctuations in our net loss as a result of transaction gains or losses related to revaluing certain current asset and current liability balances that are denominated in currencies other than the functional currency of the entities in which they are recorded. We recognized immaterial amounts of foreign currency gains and losses in each of the periods presented. We have not engaged in the hedging of our foreign currency transactions to date. We may in the future hedge selected significant transactions denominated in currencies other than the U.S. dollar as we expand our international operations and our risk grows.

Item 4. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation (pursuant to Rule 13a-15(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) of the effectiveness of our disclosure controls and procedures, as defined in Rule 13a-15(e) under the Exchange Act as of June 30, 2021.

Disclosure controls and procedures are controls and other procedures that are designed to ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized, and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include controls and procedures designed to ensure that information required to be disclosed in our company’s reports filed under the Exchange Act is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosure.

Based on the evaluation of our disclosure controls and procedures, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of June 30, 2021.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting in connection with the evaluation required by Rules 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during the period covered by this Quarterly Report on Form 10-Q that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations on Effectiveness of Controls

Management recognizes that a control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud or error, if any, have been detected. These inherent limitations include the realities that judgments in decision making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

PART II—OTHER INFORMATION

Item 1. Legal Proceedings.

From time to time, we may become involved in other legal proceedings or be subject to claims arising in the ordinary course of our business. Regardless of the outcome of any existing or future litigation, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources, and other factors.

Item 1A. Risk Factors.

There have been no material changes to the Company’s Risk Factors as disclosed in our 2020 Annual Report.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

In April 2021, as partial consideration for the acquisition of the outstanding equity of Inposia, we issued 164,416 shares of common stock, a portion of which were issued to the sellers and a portion of which were issued to the Company as acquisition holdback, payable to the Inposia shareholders over the next 18 months, subject to reduction for certain indemnification and other potential obligations of the Inposia shareholders. The shares were issued in reliance on exemption from the registration requirements of the Securities Act of 1933 pursuant to Section 4(a)(2) thereof because the issuance of securities did not involve a public offering.

Item 6. Exhibits.

In reviewing the agreements included as exhibits to this Quarterly Report on Form 10-Q, please remember that they are included to provide you with information regarding their terms and are not intended to provide any other factual or disclosure information about the Company or the other parties to the agreement. The agreements may contain representations and warranties that the parties made to each other as of specific dates. The assertions embodied in those representations and warranties were made solely for purposes of the applicable agreement and may be subject to important qualifications and limitations agreed to by the parties in connection with negotiating the terms of such agreement. In addition, such representations and warranties: (i) may not be accurate or complete as of any specified date; (ii) are modified and qualified in important part by the underlying disclosure schedules; (iii) may be subject to a contractual standard of materiality different from those generally applicable to investors; or (iv) may have been used for the purpose of allocating risk among the parties to the applicable agreement, rather than establishing matters as facts. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the applicable agreement, which subsequent information may or may not be fully reflected in Company’s public disclosures. For the foregoing reasons, the representations and warranties should not be relied upon as statements of factual information.
