The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”).

The accompanying consolidated financial statements include our accounts and the accounts of our wholly-owned subsidiaries. All material intercompany accounts and transactions have been eliminated in consolidation. Our fiscal year ends on December 31.

The preparation of consolidated financial statements in conformity with GAAP requires certain financial instruments to be recorded at fair value; requires our 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 reported amounts of revenue and expenses during the reporting periods. Significant estimates, judgments, and assumptions in these consolidated financial statements include: allocating variable consideration for revenue recognition; the amortization period for deferred commissions; the allowance for credit losses; a determination of the deferred tax asset valuation allowance and the valuation of our common stock used to determine stock-based compensation expense prior to our IPO. Because of the use of estimates inherent in the financial reporting process and given the additional or unforeseen effects from the COVID-19 pandemic, actual results could differ from those estimates, and such differences could be material to our consolidated financial statements.

COVID-19, declared a global pandemic by the World Health Organization on March 11, 2020, has caused disruption to the economies and communities of the United States and our target international markets. In the interest of public health, many governments closed physical stores and places of business deemed non-essential. This precipitated a significant shift in shopping behavior from offline to online. Our business has benefited from this shift, both in accelerated sales growth for our existing customers’ stores, and in our sales of new store subscriptions to customers. Nevertheless, we do not have certainty that those trends will continue; the COVID-19 pandemic and the uncertainty it has created in the global economy could materially adversely affect our business, financial condition, and results of operations.

Our chief operating decision maker is our chief executive officer. Our chief executive officer reviews the financial information presented on a consolidated basis for purposes of making operating decisions, allocating resources, and evaluating financial performance. Accordingly, we have determined that we operate as a single operating and reportable segment. Revenue by geographic region was as follows:

We consider all highly liquid investments with original maturities of three months or less from the date of purchase to be cash equivalents. Cash equivalents consist of money market funds and investment securities and are stated at fair value.

We maintain a portion of amounts collected through our online payment processor with the online payment processor as a security deposit for future chargebacks. Additionally, we have amounts on deposit with certain financial institutions that serve as collateral for letters of credit and lease deposits.

All marketable securities have been classified as available-for-sale and are carried at estimated fair value. We determine the appropriate classification of our investments in debt securities at the time of purchase. Securities may have stated maturities greater than one year. All marketable securities are considered available to support current operations and are classified as current assets.

For available-for-sale debt securities in an unrealized loss position, our management first assesses whether it intends to sell, or it is more likely than not that it will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to fair value and recognized in other income (expense) in the results of operations. For available-for-sale debt securities that do not meet the aforementioned criteria, our management evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, an allowance is recorded for the difference between the present value of cash flows expected to be collected and the amortized cost basis of the security. Impairment losses attributable to credit loss factors are charged against the allowance when management believes an available-for-sale security is uncollectible or when either of the criteria regarding intent or requirement to sell is met.

Any unrealized losses from declines in fair value below the amortized cost basis as a result of non-credit loss factors is recognized as a component of accumulated other comprehensive (loss) income, along with unrealized gains. Realized gains and losses and declines in fair value, if any, on available-for-sale securities are included in other income (expense) in the results of operations. The cost of securities sold is based on the specific-identification method.

Accounts receivable are stated at net of provision for expected credit losses and include unbilled receivables. Unbilled receivables arise primarily when we provide subscriptions services in advance of billing. Accounts receivable are net of an allowance for credit losses, are not collateralized, and do not bear interest. Payment terms range from due immediately to due within 90 days. The accounts receivable balance at December 31, 2021 and December 31, 2020 included unbilled receivables of $13.1 million and $7.5 million, respectively.

We assess the collectability of outstanding accounts receivable on an ongoing basis and maintain an allowance for credit losses for accounts receivable deemed uncollectible. Upon adoption of ASU 2016-13, we analyzed the accounts receivable portfolio for significant risks, historical activity, and an estimate of future collectability to determine the amount that will ultimately be collected. This estimate is analyzed quarterly and adjusted as necessary. Identified risks pertaining to our accounts receivable include the delinquency level, customer type, and current economic environment. Due to the short-term nature of such receivables, the estimate of the amount of accounts receivable that may not be collected is based on aging of the accounts receivable balances and the financial condition of customers. Adoption of ASU 2016-13 resulted in an increase in the allowance for credit losses of approximately $0.4 million as of January 1, 2020, primarily related to unbilled receivables.

Property and equipment are stated at cost, net of accumulated depreciation and amortization. Depreciation and amortization are computed using the straight-line method over the estimated useful lives or the related lease terms (if shorter).

		Estimated
		useful life
Computer equipment		3 years
Computer software		3 years
Furniture and fixtures		5 years
Leasehold improvements		1-10 years

Maintenance and repairs that do not enhance or extend the asset’s useful life are charged to operating expenses as incurred.

The carrying values of property and equipment are reviewed for impairment whenever events or changes in circumstances indicate that their net book value may not be recoverable. When such factors and circumstances exist, we compare the projected undiscounted future cash flows associated with groups of assets used in combination over their estimated useful lives against their respective carrying amounts. If projected undiscounted future cash flows are less than the carrying value of the asset group, impairment is recorded for any excess of the carrying amount over the fair value of those assets in the period in which the determination is made.

Research and development expenses consist primarily of personnel and related expenses for our research and development staff, which include: salaries, benefits, bonuses, and stock-based compensation; the cost of certain third-party contractors; and allocated overhead. Expenditures for research and development, other than internal use software costs, are expensed as incurred.

Software development costs associated with internal use software, which are incurred during the application development phase and meet other requirements under the guidance are capitalized. In addition, implementation costs of hosting arrangements that are service contracts are capitalized.

Financial instruments that potentially subject us to concentrations of credit risk consist of cash and cash equivalents, restricted cash, and accounts receivable. Our investment policy limits investments to high credit quality securities issued by the U.S. government, U.S. government-sponsored agencies, and highly rated corporate securities, subject to certain concentration limits and restrictions on maturities. Our cash and cash equivalents and restricted cash are held by financial institutions that management believes are of high credit quality. Amounts on deposit may at times exceed federally insured limits. We have not experienced any losses on our deposits of cash and cash equivalents. We are exposed to credit risk in the event of default by the financial institutions holding our cash and cash equivalents and bond issuers.

Accounts receivable are derived from sales to our customers and our strategic technology partners who operate in a variety of sectors. We do not require collateral. Estimated credit losses are provided for in the consolidated financial statements and historically have been within management’s expectations.

One of our strategic partners accounted for 14%, 15% and 12% of our revenue at December 31, 2021, 2020 and 2019, respectively, and accounted for 19%, 24% and 20% of our accounts receivable balance at December 31, 2021, 2020 and 2019, respectively.

We expense advertising costs as incurred. Advertising expenses were approximately $16.8 million, $12.9 million and $11.8 million for the years ended December 31, 2021, 2020 and 2019, respectively.

We determine if an arrangement is a lease or contains a lease at inception. At the commencement date of a lease, we recognize a liability to make lease payments and an asset representing the right to use the underlying asset during the lease term. The lease liability is measured at the present value of lease payments over the lease term. As our leases typically do not provide an implicit rate, we use our incremental borrowing rate for most leases. The right-of-use (“ROU”) asset is measured at cost, which includes the initial measurement of the lease liability and initial direct costs incurred and excludes lease incentives.

Lease terms may include options to extend or terminate the lease. We record a ROU asset and a lease liability when it is reasonably certain that we will exercise that option. Operating lease costs are recognized on a straight-line basis over the lease term.

We also lease office space under short-term arrangements and have elected not to include these arrangements in the ROU asset or lease liabilities.

We record tangible and intangible assets acquired and liabilities assumed in business combinations under the acquisition method of accounting. We use best estimates and assumptions, including but not limited to, future expected cash flows, expected asset lives, and discount rates, to assign a fair value to the tangible and intangible assets acquired and liabilities assumed in business combinations as of the acquisition date. These estimates are inherently uncertain and subject to refinement. We allocate any excess purchase price over the fair value of the tangible and identifiable intangible assets acquired and liabilities assumed to goodwill. During the measurement period, which may be up to one year from the acquisition date, adjustments to the fair value of these tangible and intangible assets acquired and liabilities assumed may be recorded, with the corresponding offset to goodwill.

Upon the conclusion of the measurement period or final determination of the fair value of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to our condensed consolidated statements of operations.

Acquisition related expenses consist primarily of cash payments for third-party acquisition costs and other acquisition related expenses. We recognized $23.3 million, $0.0 million, and $0.0 million in acquisition related expenses during the years ended December 31, 2021, 2020, and 2019, respectively. For the year ended December 31, 2021, $1.8 million was recognized on acquisition related spend and $21.5 million was recognized in connection with contingent compensation arrangements, as further discussed in Note 5 “Business Combination.” We entered into contingent compensation arrangements, in which payments will be made after the first and second anniversaries of the closing or upon the earlier achievement of certain product and financial milestones. The compensation arrangements are contingent upon continued post-acquisition employment with us. We account for the cost related to the first and second contingent compensation arrangement payments over the service periods of 12 and 24 months, respectively, beginning on the acquisition date, assuming earlier achievement of product and financial milestones is unlikely to be met.

We assess goodwill and indefinite-lived intangible assets for impairment annually during the fourth quarter, or more frequently if events or changes in circumstances would more likely than not reduce the fair value of a reporting unit below its carrying value. When we elect to perform a qualitative assessment and conclude it is not more likely than not the fair value of the reporting unit is less than its carrying value, no further assessment of that reporting unit is necessary; otherwise, a quantitative assessment is performed and the fair value of the reporting unit is determined. If the carrying value of the reporting unit exceeds the estimated fair value, impairment is recorded.

We evaluate the recoverability of finite-lived intangible assets for impairment whenever events or changes in circumstances indicate the carrying amount of such asset may not be recoverable. If such review determines the carrying amount of the indefinite-lived asset is not recoverable, the carrying amount of such asset is reduced to its fair value.

Acquired finite-lived intangible assets are amortized over their estimated useful lives. We evaluate the estimated remaining useful life of these assets when events or changes in circumstances indicate a revision to the remaining period of amortization. If we revise the estimated useful life assumption for any assets, the remaining unamortized balance is amortized over the revised estimated useful life on a prospective basis.

We account for income taxes under the asset and liability method. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax balances are adjusted to reflect tax rates based on currently enacted tax laws, which will be in effect in the years in which the temporary differences are expected to reverse. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the results of operations in the period of the enactment date. A valuation allowance is recorded to reduce the carrying amounts of deferred tax assets unless it is more likely than not that those assets will be realized. To date, we have provided a valuation allowance against all of our deferred tax assets as we believe the objective and verifiable evidence of our historical pretax net losses outweighs any positive evidence of its forecasted future results. We will continue to monitor the positive and negative evidence, and we will adjust the valuation allowance as sufficient objective positive evidence becomes available.

We recognize the tax effects of an uncertain tax position only if it is more likely than not to be sustained based solely upon its technical merits at the reporting date. The unrecognized tax benefit is the difference between the tax benefit recognized and the tax benefit claimed on our income tax return. All of our gross unrecognized tax benefits, if recognized, would not affect its effective tax rate, but would be recorded as an adjustment to equity before consideration of valuation allowances. We do not expect unrecognized tax benefits to decrease within the next twelve months. We recognize accrued interest and penalties related to unrecognized tax benefits as a component of income tax expense. As of December 31, 2021, we have not accrued any interest or penalties related to unrecognized tax benefits. We believe that all material tax positions in the current and prior years have been analyzed and properly accounted for and that the risk of additional material uncertain tax positions that have not been identified is remote.

We issue stock options, restricted stock units ("RSUs") and performance based restricted stock units (“PSUs”) to our employees and other eligible service providers. Stock-based compensation related to stock options is measured at the date of grant and is recognized on a straight-line basis over the service period, net of estimated forfeitures. We use the Black-Scholes option-pricing model to estimate the fair value of stock options awarded at the date of grant. Stock-based compensation related to RSUs is measured at the date of grant, net of estimated forfeitures, and recognized ratably over the service period. Stock-based compensation related to PSUs is measured at the date of grant and recognized using the accelerated attribution method, net of estimated forfeitures, over the remaining service period.

In August 2020, the FASB issued ASU No. 2020-06, "Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40)" which simplifies the accounting for convertible debt instruments by eliminating the requirement to separate embedded conversion features from the host contract when the conversion features are not required to be accounted for as derivatives under Topic 815, Derivatives and Hedging, or that do not result in substantial premiums accounted for as paid-in capital. In addition, the guidance eliminates the treasury stock method to calculate diluted earnings per share for convertible instruments and requires the use of the if-converted method. We adopted this standard on January 1, 2021 using the modified retrospective method. As further discussed in Note 7 “Debt”, we issued certain convertible senior notes and entered into certain contracts in the Company’s own equity during the quarter ended September 30, 2021. The accounting for these instruments was based on the guidance in ASU 2020-06.

Our functional and reporting currency and the functional and reporting currency of our subsidiaries is the U.S. dollar. Monetary assets and liabilities denominated in foreign currencies are re-measured to U.S. dollars using the exchange rates at the balance sheet dates. Non-monetary assets and liabilities denominated in foreign currencies are measured in U.S. dollars using historical exchange rates. Revenue and expenses are measured using the actual exchange rates prevailing on the dates of the transactions. Gains and losses resulting from re-measurement are recorded within Other expense in our consolidated statements of operations and were not material for all periods presented.
