Overview and Basis of Presentat

Overview and Basis of Presentation	3 Months Ended

Accounting Policies [Abstract]
Overview and Basis of Presentation	Ooma, Inc. and its wholly-owned subsidiaries (collectively, “Ooma” or the “Company”) create new communications experiences for businesses and consumers, delivered from its smart cloud-based software-as-a-service (“SaaS”) and unified-communications-as-a-service (“UCaaS”) platforms. The Company is headquartered in Sunnyvale, California. Fiscal Year. The Company’s fiscal year ends on January 31. References to fiscal 2021 and fiscal 2020 refer to the fiscal year ending January 31, 2021 and the fiscal year ended January 31, 2020, respectively. Principles of Presentation and Consolidation These unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (the “SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, the information included in this Quarterly Report on Form 10-Q should be read in conjunction with the audited consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the year ended January 31, 2020 (“Annual Report”). These financial statements have been prepared on the same basis as the Company’s annual financial statements and, in the opinion of management, reflect The condensed consolidated financial statements include accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated upon consolidation. Use of Estimates. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the Company’s condensed consolidated financial statements and notes thereto. Significant estimates include, but are not limited to, those related to revenue recognition, inventory valuation, deferred commissions, valuation of goodwill and intangible assets, operating lease assets and liabilities, regulatory fees and indirect tax accruals, loss contingencies, stock-based compensation, income taxes (including valuation allowances) and fair value measurements. The Company bases its estimates and assumptions on historical experience, where applicable, and other factors that it believes to be reasonable under the circumstances, including but not limited to the potential impacts arising from the COVID-19 pandemic. These estimates are based on information available as of the date of the condensed consolidated financial statements, and assumptions are inherently subjective in nature. Therefore, actual results could differ from management’s estimates. Significant Accounting Policies. The Company’s significant accounting policies are disclosed in its Annual Report. Comprehensive Loss. For all periods presented, comprehensive loss approximated net loss in the condensed consolidated statements of operations and differences were not material. Therefore, the condensed consolidated statements of comprehensive loss have been omitted. Adopted Accounting Standards Financial Instruments-Credit Losses . On February 1, 2020, the Company adopted Accounting Standard Update (“ASU”) 2016-13, Financial Instruments-Credit Losses (Topic 326) : Measurement of Credit Losses on Financial Instruments , which replaced the legacy incurred loss impairment model with an expected credit loss model. The Company’s accounts receivable, convertible note receivable and available-for-sale debt securities are subject to this standard. The standard was adopted using the modified retrospective transition method, with no adjustment to accumulated deficit. Adoption did not have a material impact on the Company’s condensed consolidated financial statements and related disclosures. The Company will continue to actively monitor the impact of the COVID-19 pandemic on its estimate of expected credit losses. Fair Value Measurement. On February 1, 2020, the Company adopted ASU 2018-13 , Changes to Disclosure Requirements for Fair Value Measurements (Topic 820), which improved the effectiveness of disclosure requirements for recurring and nonrecurring fair value measurements. The standard removes, modifies, and adds certain disclosure requirements. Adoption did not have an impact on the Company’s condensed consolidated financial statements and related disclosures. Accounting Standards Not Yet Adopted Income Taxes. In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740) : Simplifying the Accounting for Income Taxes , which simplifies certain aspects of the accounting for income taxes as well as clarifies and amends existing guidance to improve consistent application. The amendment is effective for the Company beginning fiscal 2022. The Company is evaluating the impact of the new guidance on its consolidated financial statements.

Revenue From Contract With Customer [Abstract]
Revenue and Deferred Revenue	Note 2: Revenue and Deferred Revenue The Company’s revenue for the three months ended April 30, 2020 and 2019 are presented in accordance with the provisions under Topic 606. The Company derives its revenue from two sources: Subscription and Services Revenue is derived primarily from recurring subscription fees related to service plans such as Ooma Business, Ooma Residential and other communications services. Subscription revenue is generally recognized ratably over the contractual service term. Service plans are generally sold as monthly subscriptions; however, certain plans are also offered as annual or multi-year subscriptions. Product and Other Revenue is generated from the sale of on-premise appliances and end-point devices, including shipping and handling fees for direct customers, and to a lesser extent from porting fees that enable customers to transfer their existing phone numbers. The Company recognizes revenue from sales to direct end-customers and channel partners at the point-in-time that control transfers, which is typically when it delivers the product or when all customer contractual provisions have been met, if any. Refer to the Company’s Annual Report for additional information regarding its revenue recognition policy. Revenue disaggregated by revenue source consisted of the following (in thousands): Three Months Ended April 30, 2020 April 30, 2019 Subscription and services revenue $ 37,616 $ 31,112 Product and other revenue 2,690 2,895 Total revenue $ 40,306 $ 34,007 The Company derived approximately 55% and 64% of its total revenue from Ooma Residential and approximately 43% and 33% from Ooma Business for the three months ended April 30, 2020 and 2019, respectively. As of April 30, 2020, one customer accounted for 22% of the Company’s net accounts receivable balance. As of January 31, 2020, no single customer accounted for 10% or more of net accounts receivable. Deferred Revenue . Deferred revenue primarily consists of billings or payments received in advance of meeting revenue recognition criteria. Deferred services revenue is recognized on a ratable basis over the term of the contract as the services are provided. For all arrangements, any revenue that has been deferred and is expected to be recognized beyond one year is classified in long term liabilities on the condensed consolidated balance sheets. Deferred revenue consisted of the following (in thousands): As of April 30, 2020 January 31, 2020 Subscription and services $ 15,430 $ 15,892 Product and other 92 79 Total deferred revenue $ 15,522 15,971 Less: current deferred revenue 15,374 15,797 Non-current deferred revenue included in other long-term liabilities $ 148 $ 174 During the three months ended April 30, 2020, the Company recognized revenue of approximately $9.3 million pertaining to amounts deferred as of January 31, 2020. As of April 30, 2020, the Company’s deferred revenue balance was primarily composed of subscription contracts that were invoiced during the first quarter of fiscal 2021, as well as amounts recorded during fiscal 2020 for annual contracts. Remaining Performance Obligations. As of April 30, 2020, contract revenue that has not yet been recognized for open contracts with an original expected length of greater than one year was approximately $6.0 million. The Company expects to recognize revenue on approximately 55% of this amount over the next 12 months, with the balance to be recognized thereafter

Amortization expense for deferred sales commissions was $0.8 million and $0.4 million for the three months ended April 30, 2020 and 2019, respectively. To date, there have been no material impairment losses related to the costs capitalized . Global In December 2018, the Company invested $1.3 million in cash to Global Telecomm Corporation, a small privately-held technology company, in exchange for an 18-month convertible promissory note, bearing interest at 10% annually, that will convert to shares of GTC common or preferred stock upon the occurrence of certain future events. The Company has partnered with GTC on certain research and development and inventory procurement activities. GTC is considered a variable interest entity (“VIE”) for accounting purposes. However, the Company is not required to consolidate GTC into its financial statements because the Company is not the primary beneficiary. As of April 30, 2020 and January 31, 2020, the Company’s maximum exposure to loss was equal to the carrying value of its convertible note receivable and associated interest receivable. For all periods presented, the Company had no other variable interests in VIEs. GTC is a related party of Ooma as a result of the convertible note. As of April 30, 2020 and January 31, 2020, the Company recorded inventory prepayments to GTC of $0.8 million and $0.5 million, respectively, included in other current assets on the consolidated balance sheet.

Income Tax Disclosure [Abstract]
Income Taxes	Note 8: Income Taxes The Company recorded no income tax expense during the three months ended April 30, 2020 and an income tax benefit of $22,000 during the three months ended April 30, 2019, primarily associated with state taxes and the Company’s acquisition of Voxter in March 2018. The Company continues to maintain a full valuation allowance against its deferred tax assets. As of April 30, 2020, the Company had unrecognized tax benefits of $6.4 million, none of which would currently affect the Company's effective tax rate if recognized due to the Company's deferred tax assets being fully offset by a valuation allowance. The Company does not anticipate that the amount of unrecognized tax benefits relating to tax positions existing at April 30, 2020 will significantly increase or decrease within the next twelve months. There were no interest expense or penalties related to unrecognized tax benefits recorded through April 30, 2020. A number of years may elapse before an uncertain tax position is audited and finally resolved. While it is often difficult to predict the final outcome or the timing of resolution of any particular uncertain tax position, the Company believes that its reserves for income taxes reflect the most likely outcome. The Company adjusts these reserves, as well as the related interest, in light of changing facts and circumstances. Settlement of any particular position could require the use of cash. On March 27, 2020, the “Coronavirus Aid, Relief and Economic Security (CARES) Act” was signed into law. The CARES Act included provisions relating to refundable payroll tax credits, deferment of the employer portion of certain payroll taxes, net operating loss carryback periods, alternative minimum tax credit refunds, modifications to the net interest deduction limitations and technical corrections to tax depreciation methods for qualified improvement property. These provisions are not expected to have a material effect on the Company’s consolidated financial statements.

Earnings Per Share [Abstract]
Basic and Diluted Net Loss Per Share	Note 9: Basic and Diluted Net Loss Per Share Basic and diluted net loss per share is calculated by dividing the net loss by the weighted average number of common shares outstanding during the period. Diluted net loss per share of common stock is the same as basic net loss per share of common stock because the effects of potentially dilutive securities are antidilutive as the Company reported net losses for all periods presented. The following table sets forth the computation of the Company’s basic and diluted net loss per share of common stock (in thousands, except share and per share data): Three Months Ended April 30, 2020 April 30, 2019 Numerator Net loss $ (1,066 ) $ (4,740 ) Denominator Weighted-average common shares 21,897,694 20,479,739 Basic and diluted net loss per share $ (0.05 ) $ (0.23 ) Potentially dilutive securities of approximately 3.8

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 10: Commitments and Contingencies Purchase Commitments . As of April 30, 2020 and January 31, 2020, non-cancelable purchase commitments with the Company’s contract manufacturers and other parties were $5.9 million and $4.0 million, respectively. Legal Proceedings In addition to the litigation matters described below, from time to time, the Company may be involved in a variety of other claims, lawsuits, investigations, and proceedings relating to contractual disputes, intellectual property rights, employment matters, regulatory compliance matters, and other litigation matters relating to various claims that arise in the normal course of business. Defending such proceedings is costly and can impose a significant burden on management and employees, the Company may receive unfavorable preliminary or interim rulings in the course of litigation, and there can be no assurances that favorable final outcomes will be obtained. The Company determines whether an estimated loss from a contingency should be accrued by assessing whether a loss is deemed probable and can be reasonably estimated. The Company assesses its potential liability by analyzing specific litigation and regulatory matters using reasonably available information. The Company develops its views on estimated losses in consultation with inside and outside counsel, which involves a subjective analysis of potential results and outcomes, assuming various combinations of appropriate litigation and settlement strategies. Legal fees are expensed in the period in which they are incurred. As of April 30, 2020, the Company did not have any accrued liabilities recorded for loss contingencies in its consolidated financial statements . Deep Green Wireless Litigation On June 8, 2016, plaintiff Deep Green Wireless LLC (“Deep Green”) filed a complaint in the U.S. District Court for the Eastern District of Texas against Ooma, Inc., alleging infringement of U.S. Patent No. RE42,714 (the “Deep Green Wireless Patent”, and such litigation, the “Deep Green Wireless Litigation ”). The complaint seeks unspecified monetary damages, costs, attorneys’ fees and other appropriate relief. In February 2017, the Court granted the Company’s motion to transfer the case to the Northern District of California, which proceeding has been stayed pending the outcome of an inter partes review of the Deep Green Wireless Patent by the United States Patent Trial and Appeal Board (“PTAB”). On December 17, 2018, the PTAB issued its final decision regarding the claims at issue in the Deep Green Wireless Litigation, in which it determined that all challenged claims of the are obvious and unpatentable. On February 19, 2019, the plaintiff filed a Notice of Appeal to the Court of Appeals for the Federal Circuit. The matter was fully briefed and oral argument was held on February 7, 2020. On March 31, 2020, the Federal Circuit affirmed the final decision by the PTAB with respect to all asserted claims of the Deep Green Wireless Patent. On April 30, 2020, Deep Green filed a Combined Petition for Panel Rehearing and Rehearing En Banc in the Federal Circuit, and on June 2, 2020, the Federal Circuit denied Deep Green’s petition. Deep Green has 90 days to petition the Supreme Court to hear the case. Based on the Company’s current knowledge, the Company has determined that the amount of any material loss or range of any losses that is reasonably possible to result from the Deep Green Wireless Litigation is not estimable. Oregon Tax Litigation On August 30, 2016, the Oregon Department of Revenue (the “DOR”) issued tax assessments against the Company for the Oregon Emergency Communications Tax (the “Tax”), which the DOR alleges Ooma should have collected from its subscribers in Oregon and remitted to the DOR during the period between January 1, 2013 and March 31, 2016 (collectively, the “Assessments”). The Company believes that the Commerce Clause of the United States Constitution bars the application of the Tax and the Assessments to the Company, since the Company has no employees, property or other indicia of a “substantial nexus” with the State of Oregon. On January 17, 2019, the Regular Division of the Oregon Tax Court heard oral arguments on the parties’ cross motions for summary judgment. On March 2, 2020, Oregon Tax Court issued a decision upholding the Assessments. On April 1, 2020, the Company filed a Notice of Appeal with the Supreme Court of the State of Oregon. However, litigation is unpredictable and there can be no assurances that the Company will obtain a favorable final outcome or that it will be able to avoid further unfavorable interim rulings in the course of litigation that may significantly add to the expense of its defense and could result in substantial costs and diversion of resources. Through January 31, 2020, the Company has recorded cumulative charges of $0.6 million as its best estimate of probable loss related to the Assessments. No additional charges were recorded during the three months ended April 30, 2020. Indemnification The Company enters into standard indemnification arrangements in the ordinary course of business. Pursuant to these arrangements, the Company indemnifies, holds harmless and agrees to reimburse the indemnified parties for losses suffered or incurred by the indemnified party, in connection with any trade secret, copyright, patent or other intellectual property infringement claim by any third party with respect to the Company’s technology. The term of these indemnification agreements is generally perpetual. The maximum potential amount of future payments the Company could be required to make under these agreements is not determinable because it involves claims that may be made against the Company in the future but have not yet been made. The Company has entered into indemnification agreements with its directors and officers that may require the Company to indemnify its directors and officers against liabilities that may arise by reason of their status or service as directors or officers, other than liabilities arising from willful misconduct of the individual. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is unlimited; however, the Company has director and officer insurance coverage that reduces the Company’s exposure and enables the Company to recover a portion of any future amounts paid. To date the Company has not incurred costs to defend lawsuits or settle claims related to these indemnification agreements. No liability associated with such indemnifications has been recorded to date.

Accounting Policies [Abstract]
Fiscal Year	Fiscal Year. The Company’s fiscal year ends on January 31. References to fiscal 2021 and fiscal 2020 refer to the fiscal year ending January 31, 2021 and the fiscal year ended January 31, 2020, respectively.
Principles of Presentation and Consolidation	Principles of Presentation and Consolidation These unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (the “SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, the information included in this Quarterly Report on Form 10-Q should be read in conjunction with the audited consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the year ended January 31, 2020 (“Annual Report”). These financial statements have been prepared on the same basis as the Company’s annual financial statements and, in the opinion of management, reflect The condensed consolidated financial statements include accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated upon consolidation.
Use of Estimates	Use of Estimates. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the Company’s condensed consolidated financial statements and notes thereto. Significant estimates include, but are not limited to, those related to revenue recognition, inventory valuation, deferred commissions, valuation of goodwill and intangible assets, operating lease assets and liabilities, regulatory fees and indirect tax accruals, loss contingencies, stock-based compensation, income taxes (including valuation allowances) and fair value measurements. The Company bases its estimates and assumptions on historical experience, where applicable, and other factors that it believes to be reasonable under the circumstances, including but not limited to the potential impacts arising from the COVID-19 pandemic. These estimates are based on information available as of the date of the condensed consolidated financial statements, and assumptions are inherently subjective in nature. Therefore, actual results could differ from management’s estimates.
Significant Accounting Policies	Significant Accounting Policies. The Company’s significant accounting policies are disclosed in its Annual Report.
Comprehensive Loss	Comprehensive Loss. For all periods presented, comprehensive loss approximated net loss in the condensed consolidated statements of operations and differences were not material. Therefore, the condensed consolidated statements of comprehensive loss have been omitted.
Adopted Accounting Standards	Adopted Accounting Standards Financial Instruments-Credit Losses . On February 1, 2020, the Company adopted Accounting Standard Update (“ASU”) 2016-13, Financial Instruments-Credit Losses (Topic 326) : Measurement of Credit Losses on Financial Instruments , which replaced the legacy incurred loss impairment model with an expected credit loss model. The Company’s accounts receivable, convertible note receivable and available-for-sale debt securities are subject to this standard. The standard was adopted using the modified retrospective transition method, with no adjustment to accumulated deficit. Adoption did not have a material impact on the Company’s condensed consolidated financial statements and related disclosures. The Company will continue to actively monitor the impact of the COVID-19 pandemic on its estimate of expected credit losses. Fair Value Measurement. On February 1, 2020, the Company adopted ASU 2018-13 , Changes to Disclosure Requirements for Fair Value Measurements (Topic 820), which improved the effectiveness of disclosure requirements for recurring and nonrecurring fair value measurements. The standard removes, modifies, and adds certain disclosure requirements. Adoption did not have an impact on the Company’s condensed consolidated financial statements and related disclosures.
Accounting Standards Not Yet Adopted	Accounting Standards Not Yet Adopted Income Taxes. In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740) : Simplifying the Accounting for Income Taxes , which simplifies certain aspects of the accounting for income taxes as well as clarifies and amends existing guidance to improve consistent application. The amendment is effective for the Company beginning fiscal 2022. The Company is evaluating the impact of the new guidance on its consolidated financial statements.
