Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The interim unaudited condensed consolidated financial statements and accompanying notes have been prepared in accordance with United States generally accepted accounting principles ("U.S. GAAP") along with instructions to Form 10-Q and Article 10 of Securities and Exchange Commission ("SEC") Regulation S-X. Certain changes in presentation have been made to conform the prior period presentation to the current period reporting. We have made certain presentation changes to distinguish and disclose as separate line items, the sales proceeds from marketable securities and the sales proceeds from our maturities of marketable securities in the Condensed Consolidated Statements of Cash Flows. We have also made certain presentation changes to distinguish and disclose as separate line items, the cash flows from purchases of property and equipment from the cash flows associated with capitalized internal-use software in the Condensed Consolidated Statements of Cash Flows. Principles of Consolidation The accompanying interim condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. Unaudited Interim Financial Statements The accompanying interim condensed consolidated balance sheet as of March 31, 2020, the related interim condensed consolidated statements of operations, the condensed consolidated statements of comprehensive loss, and the condensed consolidated statements of convertible preferred stock and stockholders' equity (deficit) for the three months ended March 31, 2020 and 2019, the condensed consolidated statements of cash flows for the three months ended March 31, 2020 and 2019, and the related footnote disclosures are unaudited. The unaudited interim condensed consolidated financial statements have been prepared in accordance with U.S. GAAP. In management’s opinion, the unaudited financial statements have been prepared on the same basis as the audited financial statements and include all adjustments, which include only normal recurring adjustments necessary for the fair presentation of our financial position as of March 31, 2020. The results for the three months ended March 31, 2020 are not necessarily indicative of the results expected for the full fiscal year or any other periods. Use of Estimates The preparation of our condensed consolidated financial statements requires us to make estimates, judgments, and assumptions that affect the reported amounts of assets, liabilities, revenue, costs and expenses, and related disclosures. Actual results and outcomes could differ significantly from our estimates, judgments, and assumptions. Significant estimates, judgments, and assumptions used in these financial statements include, but are not limited to, those related to revenue, accounts receivable and related reserves, useful lives and realizability of long-lived assets, income tax reserves, and accounting for stock-based compensation. Estimates are periodically reviewed in light of changes in circumstances, facts, and experience. The effects of material revisions in estimates are reflected in the condensed consolidated financial statements in the period of change and prospectively from the date of the change in estimate.The ongoing global COVID-19 pandemic has impacted many operational aspects of our business and may continue to do so in the future. We assessed the impact that COVID-19 had on our results of operations, including, but not limited to an assessment of our allowance for doubtful accounts, the carrying value of short-term and long-term investments, the carrying value of goodwill and other long-lived assets, and the impact to revenue recognition and cost of revenues. While the COVID-19 pandemic has not had a material adverse impact on our financial operations to date, the future impacts of the pandemic and any resulting economic impact are largely unknown and rapidly evolving. We will continue to actively monitor the impact that COVID-19 has on the results of our business operations, and may make decisions required by federal, state or local authorities, or that are determined to be in the best interests of our employees, customers, partners, suppliers and stockholders. As a result our estimates and judgments may change materially as new events occur or additional information becomes available to us. Concentrations of Credit Risk Financial instruments that potentially subject us to significant concentration of credit risk consist primarily of cash, cash equivalents, marketable securities, and accounts receivable. The primary focus of our investment strategy is to preserve capital and meet liquidity requirements. Our investment policy addresses the level of credit exposure by limiting the concentration in any one corporate issuer or sector and establishing a minimum allowable credit rating. To manage the risk exposure, we invest cash equivalents and marketable securities in a variety of fixed income securities, including government and investment-grade debt securities and money market funds. We place our cash primarily in checking and money market accounts with reputable financial institutions. Deposits held with these financial institutions may exceed the amount of insurance provided on such deposits, if any. Concentrations of credit risk with respect to accounts receivable are primarily limited to certain customers to which we make substantial sales. Our customer base consists of a large number of geographically dispersed customers diversified across several industries. To reduce risk, we routinely assess the financial strength of our customers. Based on such assessments, we believe that our accounts receivable credit risk exposure is limited. One customer accounted for 10.5% of revenue for the three months ended March 31, 2020, and 14.6% of the total accounts receivable balance as of March 31, 2020. No customer accounted for more than 10% of revenue for the three months ended March 31, 2019, or more than 10% of the total accounts receivable balance as of December 31, 2019. Significant Accounting Policies There have been no material changes to our significant accounting policies as compared to those described in “Note 2 – Summary of Significant Accounting Policies” of our Annual Report on Form 10-K for the fiscal year ended December 31, 2019. New Accounting Pronouncements to be Adopted We are an emerging growth company as defined in Jumpstart Our Business Startups Act of 2012 ("JOBS Act"). For as long as we continue to be an emerging growth company, we intend to take advantage of certain exemptions from various public company reporting requirements, including delaying adoption of new or revised accounting standards until those standards apply to private companies. In the event that we no longer qualify as an emerging growth company, we will no longer be permitted to use these reporting exemptions. In February 2016, the FASB issued new guidance, Accounting Standard Update No. 2016-02, Leases (Topic 842) ("ASU 2016-02"), which establishes the principles to report transparent and economically neutral information about the assets and liabilities that arise from leases. Accordingly, this new standard introduces a lessee model that brings most operating leases on the balance sheet and also aligns certain of the underlying principles of the new lessor model with those in the new revenue recognition standard. We are currently evaluating the appropriate transition method and impact of this guidance on our condensed consolidated financial statements and related disclosures. We expect the the standard to be effective for our interim and annual periods beginning after December 15, 2020. In June 2016, FASB issued new guidance, ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which introduces a new methodology for accounting for credit losses on financial instruments, including available-for-sale debt securities. The guidance establishes a new “expected loss model” that requires entities to estimate current expected credit losses on financial instruments by using all practical and relevant information. Any expected credit losses are to be reflected as allowances rather than reductions in the amortized cost of available-for-sale debt securities. We are currently evaluating the impact of this guidance on our condensed consolidated financial statements and related disclosures. We expect the the standard to be effective for our interim and annual periods beginning after December 15, 2020. In August 2018, the FASB issued Accounting Standards Update No. 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (ASC 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement ("ASU 2018-15"). This guidance provides that implementation costs be evaluated for capitalization using the same criteria as that used for internal-use software development costs, with amortization expense being recorded in the same income statement expense line as the hosted service costs and over the expected term of the hosting arrangement. We are currently evaluating the impact of this guidance on our condensed consolidated financial statements and related disclosures. We expect the the standard to be effective for our interim and annual periods beginning after December 15, 2020. On December 18, 2019, the FASB released ASU 2019-12 which affects general principles within Topic 740, Income Taxes. The amendments of ASU 2019-12 are meant to simplify and reduce the cost of accounting for income taxes. The FASB has stated that the ASU is being issued as part of its Simplification Initiative, which is meant to reduce complexity in accounting standards by improving certain areas of generally accepted accounting principles (GAAP) without compromising information provided to users of financial statements. We are currently evaluating the impact of this guidance on our condensed consolidated financial statements and related disclosures. We expect the the standard to be effective for our interim and annual periods beginning after December 15, 2020.
