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:

	Year ended December 31,

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.

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, 2020 and December 31, 2019 included unbilled receivables of $7.5 million and $4.0 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 uncollectable. 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. To date, software costs eligible for capitalization have not been significant.

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 15% of our revenue for the year ended December 31, 2020 and 12% of our revenue for each of the years ended December 31, 2019 and 2018, and accounted for 24%, 20% and 22% of our accounts receivable balance at December 31, 2020, 2019 and 2018, respectively.

We expense advertising costs as incurred. Advertising expenses were approximately $12.9 million, $11.8 million and $8.9 million for the years ended December 31, 2020, 2019 and 2018, 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 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 account for uncertain tax positions in accordance with ASC 740, “Income Taxes”, which clarifies the accounting for uncertainty in tax positions. These provisions require recognition of the impact of a tax position in our financial statements only if that position is more likely than not of being sustained upon examination by taxing authorities, based on the technical merits of the position. Any interest and penalties related to uncertain tax positions will be reflected as a component of income tax expense.

We issue stock options and restricted stock units ("RSUs"). 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 restricted stock units is measured at the date of grant and recognized using the accelerated attribution method, net of forfeitures, over the remaining service period.

In June 2018, the FASB Issued ASU 2018-07, Compensation—Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting, which expands the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. The new guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The adoption of this standard on January 1, 2020 did not have a material impact on our consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments—Credit Losses (Topic 326)” which modifies the measurement of expected credit losses of certain financial instruments. Credit losses on trade and other receivables, available-for-sale debt securities, and other instruments will reflect our current estimate of the expected credit losses and will generally result in the earlier recognition of allowance for losses. The new guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, with early adoption permitted. The adoption of the new standard resulted in the recording of a cumulative-effect adjustment to accumulated deficit of $0.4 million on January 1, 2020. We will continue to actively monitor the impact of the recent COVID-19 pandemic on expected credit losses.

In August 2018, the FASB issued ASU No. 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40), which aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). We adopted this guidance on January 1, 2020 on a prospective basis, which did not result in a material impact to our consolidated financial statements.

In December 2019, the FASB issued ASU No. 2019-12, “Income Taxes (Topic 740) Simplifying the Accounting for Income Taxes,” as part of its initiative to reduce complexity in the accounting standards. The amendments in ASU 2019-12 eliminate certain exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. ASU 2019-12 also clarifies and simplifies other aspects of the accounting for income taxes. Although the amendments in ASU 2019-12 become effective for fiscal years beginning after December 15, 2020, we elected to early adopt the ASU as of January 1, 2019 on a prospective basis. There is no material tax impact of the early adoption of ASU 2019-12 on our financial position and results of operations.

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.
