Accounting Policies [Abstract]
Overview	Note 1: Overview Ooma, Inc. (“Ooma” or the “Company”) creates new communications experiences for businesses and consumers, delivered from its software-as-a-service (“SaaS”) and unified-communications-as-a-service (“UCaaS”) platforms. The Company’s corporate headquarters is located in Sunnyvale, California. Fiscal Year. The Company’s fiscal year ends on January 31. References to fiscal 2022 and fiscal 2021 refer to the fiscal year ending January 31, 2022 and the fiscal year ended January 31, 2021, respectively. Basis of Presentation. The accompanying 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 (“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. The condensed consolidated balance sheet as of January 31, 2021 included herein was derived from the audited financial statements as of that date, but does not include all the disclosures required by GAAP. Therefore, the information included in this Quarterly Report on Form 10-Q should be read in conjunction with the audited consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended January 31, 2021 filed with the SEC on April 7, 2021 (“Annual Report”). The accompanying condensed consolidated financial statements reflect all normal recurring adjustments that management believes are necessary for a fair presentation of the interim periods presented. The results for the three and nine months ended October 31, 2021 are not necessarily indicative of the results to be expected for any subsequent quarter or for the fiscal year ending January 31, 2022. Principles of Consolidation. The condensed consolidated financial statements include the accounts of Ooma, Inc. and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in 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. 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 materially from those estimates, including uncertainty in the current economic environment due to COVID-19. Significant Accounting Policies. There have been no material changes to the Company’s significant accounting policies from those disclosed in the 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 Income Taxes. On February 1, 2021, the Company adopted Accounting Standards Update (“ASU”) 2019-12, Income Taxes (Topic 740) : Simplifying the Accounting for Income Taxes , which simplified certain aspects of the accounting for income taxes as well as clarified and amended existing guidance to improve consistent application. Adoption did not have a material impact on the Company’s consolidated financial statements and related disclosures.

Fair Value Measurements	Note 3: Fair Value Measurements The Company records its financial assets and liabilities at fair value. The Company estimates and categorizes fair value by applying the following hierarchy: Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2: Observable prices based on inputs not quoted in active markets, but are corroborated by market data. Level 3: Unobservable inputs that are supported by little or no market activity. Financial assets measured at fair value on a recurring basis by level were as follows (in thousands): Balance as of October 31, 2021 Level 1 Level 2 Total Cash and cash equivalents: Money market funds $ 2,314 $ — $ 2,314 Total cash equivalents $ 2,314 $ — $ 2,314 Cash 17,126 Total cash and cash equivalents $ 19,440 Short-term investments: U.S. treasury securities $ 6,798 $ — $ 6,798 Commercial paper — 4,799 4,799 Total short-term investments $ 6,798 $ 4,799 $ 11,597 Balance as of January 31, 2021 Level 1 Level 2 Total Cash and cash equivalents: Money market funds $ 1,657 $ — $ 1,657 U.S. agency securities — 1,000 1,000 U.S. treasury securities 250 — 250 Total cash equivalents $ 1,907 $ 1,000 $ 2,907 Cash 14,391 Total cash and cash equivalents $ 17,298 Short-term investments: U.S. treasury securities $ 9,782 $ — $ 9,782 Corporate debt securities — 929 929 Asset-backed securities — 302 302 Total short-term investments $ 9,782 $ 1,231 $ 11,013 The Company classifies its cash equivalents and short-term investments within Level 1 or Level 2 because it uses quoted market prices or alternative pricing sources and models utilizing market observable inputs to determine their fair value. The Company has no Level 3 assets or liabilities. For the periods presented, the amortized cost of cash equivalents and marketable securities approximated their fair value and there were no material realized or unrealized gains or losses, either individually or in the aggregate. Contractual maturities of short-term investments were as follows (in thousands): As of October 31, 2021 January 31, 2021 Due in one year or less $ 9,604 $ 11,013 Due after one year to two years 1,993 — Total $ 11,597 $ 11,013

Income Taxes	Note 8: Income Taxes The Company recorded no income tax expense during the three and nine months ended October 31, 2021 and 2020. The Company continues to maintain a full valuation allowance against its deferred tax assets. As of October 31, 2021, the Company had unrecognized tax benefits of $7.4 million, none of which would currently affect its 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 October 31, 2021 will significantly increase or decrease within the next twelve months. There were no interest expense or penalties related to unrecognized tax benefits recorded through October 31, 2021. 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.

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 basic and diluted net loss per share of common stock (in thousands, except share and per share data): Three Months Ended Nine Months Ended October 31, 2021 October 31, 2020 October 31, 2021 October 31, 2020 Numerator Net loss $ (326 ) $ (413 ) $ (1,652 ) $ (1,846 ) Denominator Weighted-average common shares 23,619,406 22,531,047 23,348,529 22,222,659 Basic and diluted net loss per share $ (0.01 ) $ (0.02 ) $ (0.07 ) $ (0.08 ) Potentially dilutive securities of approximately 3.2

Financing Arrangements	Note 10: Financing Arrangements Revolving Credit Facility On January 8, 2021, the Company, as borrower, entered into a three year credit and security agreement (“Credit Agreement”) with KeyBank National Association as Administrative Agent (“Agent”) and lender, and KeyBanc Capital Markets Inc. as sole lead arranger and sole book runner. The Credit Agreement provides for a secured revolving credit facility (“Credit Facility”) under which the Company may borrow up to an aggregate amount of $25.0 million, which includes a $10.0 million sub-facility for letters of credit. The Company and its lenders may increase the total commitments under the Credit Facility to up to an aggregate amount of $45 million, subject to certain conditions. Funds borrowed under the Credit Agreement may be used for working capital and other general corporate purposes. The Credit Agreement contains customary representations, warranties, affirmative and negative covenants, events of default and indemnification provisions in favor of the Agent, lenders and their affiliates. Among other covenants, the Credit Agreement includes restrictive financial covenants that require the Company to meet minimum recurring revenue levels and maintain specified amounts of available liquidity on a quarterly basis. As of October 31, 2021, the Company had zero outstanding borrowings and was in compliance with the covenants contained in the Credit Agreement. Accordingly, $25.0 million of borrowing capacity was available for the purposes permitted by the Credit Agreement.

Commitments and Contingencies	Note 11: Commitments and Contingencies Purchase Commitments . As of October 31, 2021 and January 31, 2021, the Company’s non-cancelable purchase commitments to contract manufacturers and other suppliers, including GTC as described in Note 4 above, were $12.8 million and $5.4 million, respectively. Additionally, the Company has a non-cancelable service agreement with a telecommunications provider that contains total annual minimum purchase commitments of $0.6 million between August 2021 and July 2022, $1.5 million between August 2022 and July 2023 and $2.5 million between August 2023 and July 2024. 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 October 31, 2021 and January 31, 2021, the Company did not have any accrued liabilities recorded for loss contingencies in its consolidated financial statements . 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 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. On May 6, 2021, the Supreme Court of the State of Oregon heard oral argument with respect to Ooma’s appeal. It is not certain when a decision will be forthcoming. 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. In prior fiscal years, the Company recorded and has paid cumulative charges of $0.6 million to the DOR as its best estimate of probable loss related to the Assessments. Canadian Litigation On February 3, 2021, plaintiff Fiona Chiu filed a class action complaint against the Company and Ooma Canada Inc. in the Federal Court of Canada, alleging violations of Canada’s Trademarks Act and Competition Act. The complaint seeks monetary and other damages and/or injunctive relief enjoining the Company to cease describing and marketing its Basic Home Phone using the word “free” or otherwise representing that it is free. On November 9, 2021, the Federal Court of Canada removed Ms. Chiu and substituted John Zanin as the new plaintiff in the proceeding. In connection with the substitution of Mr. Zanin as the new plaintiff, the Federal Court of Canada deemed the proceeding as having commenced on November 8, 2021 instead of February 3, 2021. The Company intends to defend itself vigorously against this complaint. Based on the Company’s current knowledge, the Company has determined that the amount of any reasonably possible loss resulting from the Canadian Litigation is not estimable. 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.

Basis of Presentation	Basis of Presentation. The accompanying 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 (“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. The condensed consolidated balance sheet as of January 31, 2021 included herein was derived from the audited financial statements as of that date, but does not include all the disclosures required by GAAP. Therefore, the information included in this Quarterly Report on Form 10-Q should be read in conjunction with the audited consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended January 31, 2021 filed with the SEC on April 7, 2021 (“Annual Report”).

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. 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 materially from those estimates, including uncertainty in the current economic environment due to COVID-19.
Significant Accounting Policies	Significant Accounting Policies. There have been no material changes to the Company’s significant accounting policies from those disclosed in the Annual Report.
