Such estimates include, but are not limited to, revenue recognition, allowances for doubtful accounts, the incremental borrowing rate related to the Company’s lease liabilities, stock-based compensation, fair value of the liability component of the convertible debt, fair value of common stock and redeemable convertible preferred stock warrants prior to the initial public offering, legal contingencies, fair value of acquired intangible assets and goodwill, useful lives of acquired intangible assets and property and equipment and accounting for income taxes. The Company bases these estimates on historical and anticipated results, trends and various other assumptions that it believes are reasonable under the circumstances, including assumptions as to future events.</span></div><div style="line-height:120%;padding-bottom:12px;text-align:left;text-indent:36px;font-size:10pt;"><span style="font-family:Times New Roman;font-size:10pt;">The COVID-19 pandemic is expected to result in a global slowdown of economic activity that is likely to decrease demand for a broad variety of goods and services, including from the Company’s customers, while also disrupting sales channels and marketing activities for an unknown period of time. The Company currently expects its revenue to be negatively impacted by the slowdown in activity associated with the COVID-19 pandemic for the year ending January 31, 2021. </span></div><div style="line-height:120%;padding-bottom:12px;text-align:left;text-indent:36px;font-size:10pt;"><span style="font-family:Times New Roman;font-size:10pt;">Estimates and assumptions about future events and their effects cannot be determined with certainty and therefore require the exercise of judgment. As of the date of issuance of these financial statements, the Company is not aware of any specific event or circumstance that would require the Company to update its estimates, assumptions and judgments or revise the carrying value of its assets or liabilities. These estimates may change as new events occur and additional information is obtained and are recognized in the consolidated financial statements as soon as they become known. Actual results could differ from those estimates and any such differences may be material to the Company’s financial statements.</span></div>

Accounts receivable are recorded at the invoiced amount and do not bear interest. The Company records an allowance for doubtful accounts relating to certain trade accounts receivable based on various factors, including the review of credit profiles of its customers, contractual terms and conditions, current economic trends and historical customer payment experience.</span></div>
