Accounting Policies [Abstract]
Overview and Basis of Presentation	Note 1: 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 SaaS and UCaaS platforms. The Company is headquartered in Sunnyvale, California. Principles of Presentation and Consolidation. The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and include the accounts of the Company and its wholly owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. In the opinion of the Company’s management, the consolidated financial statements reflect all adjustments, which are normal and recurring in nature, necessary for fair financial statement presentation. Fiscal Year. The Company’s fiscal year ends on January 31. References to fiscal 2021, fiscal 2020 and fiscal 2019 refer to the fiscal years ended January 31, 2021, January 31, 2020 and January 31, 2019, respectively. Use of Estimates. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the Company’s consolidated financial statements and accompanying notes. 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 consolidated financial statements, and assumptions are inherently subjective in nature. Therefore, actual results could differ from management’s estimates. Comprehensive Loss. For all periods presented, comprehensive loss approximated net loss in the consolidated statements of operations and differences were not material. Therefore, the Consolidated Statements of Comprehensive Loss have been omitted. Segment Reporting. The chief operating decision maker for the Company is the chief executive officer, who reviews the Company’s financial information presented on a consolidated basis for purposes of allocating resources and evaluating financial performance. Accordingly, management has determined that the Company operates in a single Revenue was principally derived from customers located in the United States for all periods presented, with a small portion attributable to customers loca ted in Canada and other countries.

Significant Accounting Policies

Accounting Policies [Abstract]
Significant Accounting Policies	Note 2: Significant Accounting Policies Revenue Recognition The Company derives its revenue from two sources: (1) subscription and services revenue, which is derived primarily from the sale of subscription plans for communications services and other connected services; and (2) product and other revenue. Subscriptions and services are sold directly to end-customers. Products are sold to end-customers through several channels, including but not limited to distributors, retailers and resellers (collectively “channel partners”), and Ooma sales representatives. Under Topic 606, the Company determines revenue recognition through the following steps: • identification of the contract(s) with a customer; • identification of the performance obligations in the contract; • determination of the transaction price; • allocation of the transaction price to the performance obligations in the contract; and • recognition of revenue when, or as, the Company satisfies a performance obligation Subscription and Services Revenue. Most of the Company’s revenue is derived from recurring subscription fees related to service plans such as Ooma Business, Ooma Residential and other communications services. Service plans are generally sold as monthly subscriptions; however, certain plans are also offered as annual or multi-year subscriptions. Subscription revenue is generally recognized ratably over the contractual service term. A small portion of total revenue is recognized on an over-time basis from installation-related services and on a point-in-time basis from services such as: prepaid international calls, directory assistance, and advertisements displayed through its Talkatone mobile application. Product and Other Revenue. Product and other revenue is generated from the sale of on-premise appliances and end-point devices, 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. The Company’s distribution agreements with channel partners typically contain clauses for price protection and right of return. Credits and/or rebates issued for expected product returns and sales incentives are deemed to be variable consideration under Topic 606, which the Company estimates and records as a reduction to revenue at the point of sale. Product returns and customer sales incentives are estimated based on the Company’s historical experience, current trends and expectations regarding future experience. As of January 31, 2021 and 2020, the Company had total reserves for product returns and sales incentives of approximately $1.1 million and $1.4 million, respectively. Revenue is recorded net of any sales and telecommunications taxes collected from customers to be remitted to government authorities. Amounts billed to customers related to shipping and handling are classified as product and other revenue. Shipping and handling costs are expensed as incurred and classified as cost of revenue. Multiple performance obligations. The Company’s contracts with customers typically contain multiple performance obligations that consist of product(s) and related communications services. For these contracts, individual performance obligations are accounted for separately if they are distinct. The contract transaction price is then allocated to the separate performance obligations on a relative stand-alone selling price basis. The Company determines the SSP for its communications services based on observable historical stand-alone sales to customers, for which a substantial majority of selling prices must fall within a reasonably narrow pricing range. The Company establishes SSP for its on-premise appliances and end-point devices based upon management’s best estimates and judgments, considering company-specific factors such as pricing strategies, discounting practices, and estimated product and other costs. Cash Equivalents and Short-term Investments. All highly liquid investments with an original maturity of three months or less at the date of purchase are classified as cash equivalents. Short-term investments are classified as available-for-sale and carried at fair value, with unrealized gains and losses, net of tax, recorded as a separate component of stockholders’ equity within accumulated other comprehensive income. The cost of securities sold is based upon the specific identification method. Fair Value of Financial Instruments. The Company records its financial assets and liabilities at fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the reporting date. The Company estimates and categorizes the fair value of its financial assets 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 Transfers among Level classifications are recognized as of the actual date of the events or change in circumstances that caused the transfers. The carrying value of the Company’s financial instruments, including cash equivalents, accounts receivable, inventory, accounts payable and other current assets and current liabilities approximates fair value due to their short maturities. Concentration of Credit Risk. Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash equivalents, short-term investments, accounts receivable and convertible note receivable. The Company’s cash equivalents and short-term investments are held by financial institutions that management believes are of high-credit quality. Such investments and deposits may, at times, exceed federally insured limits. The Company performs credit evaluations of its channel partners’ financial condition and generally does not require collateral for sales made on credit. As of January 31, 2021, one customer accounted for 10% of the Company’s net accounts receivable balance. As of January 31, 2020, no single customer accounted for 10% or more of the Company’s net accounts receivable balance. Accounts Receivable. Accounts receivable are recorded net of an allowance for doubtful accounts for estimated credit losses. Allowances are recorded based upon the Company’s assessment of several factors, including historical experience, aging of receivable balances and economic conditions. As of January 31, 2021 and 2020, the allowance for doubtful accounts was $0.3 million and $0.2 million, respectively. Bad debt expense recorded in the consolidated statement of operations was not material for the periods presented. Inventories. Inventories, which consist of raw materials and finished goods, include the cost to purchase manufactured products, allocated labor and overhead. Inventories are stated at the lower of actual cost or market on a first-in, first-out basis. The Company’s assessment of market value requires the use of estimates regarding the net realizable value of its inventory balances, including management’s assessment of excess or obsolete inventory based upon forecast demand and market conditions. Adjustments to reduce inventory to net realizable value are recognized as a component of cost of revenue in the consolidated statement of operations. Customer Acquisition Costs. Sales commissions and other costs paid to internal sales personnel, third-party sales entities and value-added resellers are considered incremental and recoverable costs of obtaining customer contracts. (The resellers are selling agents for the Company and earn sales commissions that are directly tied to the value of the contracts that the Company enters with the end-user customers.) In accordance with Topic 606, these costs are capitalized and amortized on a systematic basis over the expected period of benefit of five years, or customer contractual term for multi-year contracts, calculated based on both qualitative and quantitative factors, such as expected subscription term and expected renewal periods of its customer contracts, product life cycles and customer attrition. Amortization expense is recorded in sales and marketing expenses in the consolidated statement of operations. The Company pays sales commissions on initial contracts and contracts for increased purchases with existing customers (expansion contracts) and does not pay commissions for contract renewals. The Company periodically evaluates whether there have been any changes in its business, the market conditions in which it operates or other events which would indicate that its amortization period should be changed or if there are potential indicators of impairment. To date, there have been no material impairment losses related to the costs capitalized. Internal-Use Website Development Costs. The Company capitalizes certain costs to develop its websites when preliminary development efforts are successfully completed, management has authorized and committed project funding, and it is probable that the project will be completed and the software will be used as intended. Such costs primarily include payroll-related costs for engineers and contractors directly associated with the development project. Capitalized website development costs are included in property and equipment and are amortized on a straight-line basis over an estimated useful life of two years. Costs related to preliminary project activities and post-implementation activities are expensed as incurred. Property and Equipment, net. Property and equipment, net is stated at cost, less accumulated depreciation and amortization. Depreciation and amortization is computed on a straight-line basis over the estimated useful lives of those assets, generally two to five years. Leasehold improvements are amortized over the shorter of the lease term or estimated useful lives of the respective assets. Repairs and maintenance costs that do not extend the life or improve the asset are expensed as incurred. Operating Leases. The Company determines if an arrangement is a lease at inception. The Company’s leases primarily consist of real property and are classified as operating leases. The Company does not have any finance leases nor material arrangements as a lessor. Right-of-use lease assets and lease liabilities are recognized at the lease commencement date based upon the present value of the remaining lease payments over the lease term. The Company uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. Lease expense for lease payments is recognized on a straight-line basis over the term of the lease. Lease terms may include options to renew or extend when it is reasonably certain that the option will be exercised. Lease agreements that contain both lease and non-lease components are accounted for as a single component. Short-term leases with an initial term of twelve months or less are not recorded on the balance sheet. Financial results and disclosure requirements for reporting periods beginning after February 1, 2019 are presented under Topic 842, while prior period amounts have not been adjusted and continue to be reported under Topic 840. Goodwill. Goodwill represents the excess of the purchase price over the fair value of the net assets acquired in a business combination. Goodwill is evaluated for impairment annually in the fourth quarter of its fiscal year, or more frequently if indicators of potential impairment arise. The Company has a single reporting unit and consequently evaluates goodwill for impairment based on an evaluation of the fair value of the Company as a whole. No impairment has been recognized for any of the periods presented. Intangible Assets. Acquired intangible assets other than goodwill, which primarily consist of developed technology and customer relationships, are amortized over their useful lives unless the lives are determined to be indefinite. For intangible assets acquired in a business combination, the estimated fair values of the assets received are used to establish their recorded values. Valuation techniques consistent with the market approach, income approach and/or cost approach are used to measure fair value. Impairment of Long-Lived Assets. Long-lived assets, such as property and equipment, capitalized website development costs, and intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the fair value of the asset. During fiscal 2020, the Company recorded impairment charges of $0.7 million to cost of product revenue for abandoned developed technology and trade names associated with the Ooma Smart Cam, which was acquired through the fiscal 2018 acquisition of Butterfleye, Inc. and discontinued in October 2019. The Company did not record any material impairment charges for fiscal 2021 or fiscal 2019. Research and Development. Research and development costs are charged to operating expenses as incurred in the consolidated statements of operations, except for internal-use website development costs that qualify for capitalization, as per above. Research and development expenses consist primarily of personnel-related costs for employees and contractors, including stock-based compensation, as well as license and product certification fees, and allocated costs of facilities and information technology. Advertising. Advertising costs are included in sales and marketing and expensed as incurred, except for production costs associated with television and radio advertising, which are expensed on the first date of airing. Advertising costs were $12.2 million, $13.6 million and $13.7 million for fiscal 2021, 2020 and 2019, respectively. Advertising payments to the Company’s channel partners recorded as a reduction in revenue totaled $0.3 million, $0.4 million and $0.3 million for fiscal 2021, 2020 and 2019, respectively. Stock-Based Compensation. Stock-based compensation expense for all stock-based awards granted to employees and non-employee directors is measured at the grant date fair value of the equity award. The fair value of options granted and purchase rights under the Company’s ESPP are estimated on the date of grant using the Black-Scholes pricing model. The fair value of each RSU granted is determined using the fair value of the Company’s common stock on the date of grant. Compensation expense is recognized using the straight-line method over the requisite service period, which is generally the vesting period. Forfeitures are recorded in the period in which they occur. Income Taxes. Income taxes are recorded using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income (loss) in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. A tax position is recognized when it is more-likely-than-not that the tax position will be sustained upon examination, including resolution of any related appeals or litigation processes. A tax position that meets the more likely than not recognition threshold is measured at the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement with a taxing authority. Interest and penalties associated with unrecognized tax benefits are classified as income tax expense. The Company had no interest or penalty accruals associated with uncertain tax benefits in its consolidated balance sheets and statements of operations for any periods presented. Foreign currency. The U.S. dollar is the functional currency of the Company's foreign subsidiaries. Remeasurement and transaction gains and losses are included in interest and other income, net and were not material for any periods presented. 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 were 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 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. 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 as well as clarifies and amends existing guidance to improve consistent application.

Expected volatility is derived from a combination of the average historical volatility of the Company’s own common stock and a group of comparable publicly traded companies. The risk-free interest rate is based on the yields of U.S. Treasury securities with maturities similar to the expected term.

If not utilized, these available carryforward losses will expire in various amounts for federal and state tax purposes beginning in 2030. In addition, the Company had research and development tax credits for federal and state purposes of approximately $8.4 million and $8.3 million, respectively, available to offset future taxes. If not utilized, the available federal credits will begin to expire in 2030. California state research and development tax credits can be carried forward indefinitely. Uncertain Tax Positions The Company has unrecognized tax benefits of approximately $6.6 million as of January 31, 2021. Deferred tax assets associated with these unrecognized tax benefits are fully offset by a valuation allowance. If recognized, these benefits would not affect the effective tax rate before consideration of the valuation allowance. The following table summarizes the activity related to unrecognized tax benefits (in thousands): Balance at January 31, 2019 $ 4,425 Increase related to current year tax positions 1,592 Balance at January 31, 2020 6,017 Decrease related to prior year positions (362 ) Increase related to current year tax positions 987 Balance at January 31, 2021 $ 6,642 The Company had no interest or penalty accruals associated with uncertain tax benefits in its balance sheets and statements of operations. The Company does not have any tax positions for which it is reasonably possible the total amount of gross unrecognized benefits will increase or decrease within 12 months of the year ended January 31, 2021. Because the Company has net operating loss and credit carryforwards, there are open statutes of limitations in which federal, state and foreign taxing authorities may examine the Company’s tax returns for all years from 2009 through the current period. The Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) and the Consolidated Appropriations Act (“CAA”), were enacted on March 27, 2020 and December 27, 2020, respectively, to respond to the economic challenges due to COVID-19. The Company reviewed the tax law changes included in the CARES Act and the CAA, and determined there was no material impact to its effective tax rate.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 11: Commitments and Contingencies Purchase Commitments As of January 31, 2021 and 2020, non-cancelable purchase commitments with the Company’s contract manufacturers and other parties were $5.4 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 January 31, 2021, the Company does 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. 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 recorded and paid cumulative charges of $0.6 million as its best estimate of probable loss related to the Assessments. No additional charges were recorded during the year ended January 31, 2021. Chiu 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. 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 loss resulting from the Chiu 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 certain losses suffered or incurred by the indemnified party. In some cases, the term of these indemnification agreements is 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.

Loans under the Credit Agreement will bear interest, at the Company’s option, at either a rate equal to the “Base Rate” (as defined in the Credit Agreement) or (b) “Eurodollar Rate” (as defined in the Credit Agreement) plus 2.50%. The Base Rate is the highest of (i) the Agent’s prime rate, (ii) the federal funds effective rate plus 0.5%, and (iii) the Eurodollar Rate with an interest period of one month plus 1%. The Eurodollar Rate is the London Interbank Offered Rate with various interest periods as may be selected by the Company but shall not be less than 0.75%. Upon the occurrence of any event of default, the interest rate on any borrowings increases by 2.0%. The Credit Agreement also contains customary provisions for the replacement of the London Interbank Offered Rate/Eurodollar Rate. The Company is required to pay a commitment fee on the unused portion of the Credit Facility of 0.25% per annum. The Credit Agreement will terminate and all amounts owing thereunder will be due and payable on the earlier of January 7, 2024 or 90 days prior to the scheduled maturity of any convertible debt securities, unless the commitments are terminated earlier, either at the request of the Company or, if an event of default occurs, by the lenders (or automatically in the case of certain bankruptcy-related events). 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 January 31, 2021, the Company had zero outstanding borrowings and was in compliance with the covenants contained in the Credit Agreement. Accordingly, $25 million of borrowing capacity was available for the purposes permitted by the Credit Agreement.

Business Acquisitions And Divestitures [Abstract]
Business Acquisitions	Note 13: Business Acquisitions Broadsmart Global, Inc. On May 24, 2019, the Company acquired all outstanding stock of Broadsmart, a provider of cloud-based UCaaS solutions based in Florida. The cash consideration transferred for Broadsmart was $7.1 million, net of cash assumed of $0.6 million. The Company acquired Broadsmart to provide scale for the Ooma Office and Ooma Enterprise platforms, which aligns with the Company’s overall enterprise growth strategy. The fair values of assets acquired and liabilities assumed as of the date of acquisition was as follows (in thousands): Fair Value Cash $ 649 Accounts receivable 1,003 Other current and non-current assets 639 Intangible assets 6,107 Goodwill 366 Accounts payable and other liabilities (1,043 ) Net assets acquired $ 7,721 Intangible assets acquired consisted of customer relationships of $5.8 million and trade names of $0.3 million. The goodwill recognized was attributable to the assembled workforce and expanded market opportunities when integrating Broadsmart’s offerings with Ooma Business. The acquisition of Broadsmart was treated as an asset purchase for income tax purpose, and therefore, the transaction did not result in the recording of deferred taxes as the Company's tax basis in the acquired assets equaled its book basis. The resulting goodwill from this acquisition was deductible for U.S. income tax purposes. Broadsmart revenue included in the Company’s consolidated statement of operations from the May 24, 2019 acquisition date through January 31, 2020 was approximately $7.0 million. On an unaudited pro forma basis, had the Broadsmart acquisition been included in the Company’s consolidated results of operations beginning February 1, 2018, the Company’s total revenue for fiscal 2020 and 2019 would have approximated $153 million and $138 million, respectively. These pro forma revenue amounts were adjusted to exclude revenue associated with a legacy Broadsmart customer that was not expected to be a continuing customer for the combined entity. These pro forma revenue amounts do not necessarily represent what would have occurred if the business combination had taken place on February 1, 2018, nor do these amounts represent the results that may occur in the future. Actual and pro forma net loss for the Broadsmart acquisition have not been presented because the impact was not material to the Company's consolidated statement of operations. Voxter Communications, Inc. On March 12, 2018, the Company acquired all outstanding stock of Voxter, a provider of UCaaS offerings based in Vancouver, British Columbia. The acquisition date fair value consideration transferred for Voxter was approximately $3.9 million, which primarily consisted of cash and common stock. The final purchase price allocation included identifiable intangible assets of approximately $2.1 million, net assets acquired of approximately $0.4 million, deferred tax liabilities of approximately $0.4 million and residual goodwill of approximately $2.0 million, based on the best estimates of management. The goodwill recognized was attributable primarily to expected synergies in the acquired technologies that may be leveraged by the Company in future Ooma Business offerings. Goodwill was not deductible for U.S. or Canadian income tax purposes. Actual and pro forma results of operations for the Voxter acquisition have not been presented because the impact was not material to the Company's consolidated results of operations.

Earnings Per Share [Abstract]
Net Loss Per Share	Note 14: Net Loss Per Share Basic and diluted net loss per share of common stock is calculated by dividing the net loss allocable to common stockholders 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 because the effects of potentially dilutive securities are antidilutive because the Company reported net losses for all periods presented. The following table sets forth the computation of basic and diluted net loss per share (in thousands, except share and per share data): Fiscal Year Ended January 31, 2021 2020 2019 Numerator Net loss $ (2,441 ) $ (18,801 ) $ (14,572 ) Denominator Weighted-average common shares 22,361,312 21,051,039 19,799,781 Basic and diluted net loss per share $ (0.11 ) $ (0.89 ) $ (0.74 ) Potentially dilutive securities of approximately 3.3 million, 3.2 million and 3.9 million were excluded from the computation of diluted net loss per share for fiscal 2021, 2020 and 2019, respectively. These shares include the Company’s outstanding RSUs, outstanding stock options and shares to be purchased under the ESPP at the end of the respective purchase period. In the event the Company reported net income for the periods presented, a portion of these outstanding securities would be reflected in weighted-average shares outstanding for diluted earnings per share by application of the treasury method.

Significant Accounting Polici_2

Significant Accounting Policies (Policies)	12 Months Ended
	Jan. 31, 2021
Accounting Policies [Abstract]
Principles of Presentation and Consolidation	Principles of Presentation and Consolidation. The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and include the accounts of the Company and its wholly owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. In the opinion of the Company’s management, the consolidated financial statements reflect all adjustments, which are normal and recurring in nature, necessary for fair financial statement presentation.
Fiscal Year	Fiscal Year. The Company’s fiscal year ends on January 31. References to fiscal 2021, fiscal 2020 and fiscal 2019 refer to the fiscal years ended January 31, 2021, January 31, 2020 and January 31, 2019, respectively.
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 amounts reported in the Company’s consolidated financial statements and accompanying notes. 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 consolidated financial statements, and assumptions are inherently subjective in nature. Therefore, actual results could differ from management’s estimates.
Comprehensive Loss	Comprehensive Loss. For all periods presented, comprehensive loss approximated net loss in the consolidated statements of operations and differences were not material. Therefore, the Consolidated Statements of Comprehensive Loss have been omitted.
Segment Reporting	Segment Reporting. The chief operating decision maker for the Company is the chief executive officer, who reviews the Company’s financial information presented on a consolidated basis for purposes of allocating resources and evaluating financial performance. Accordingly, management has determined that the Company operates in a single Revenue was principally derived from customers located in the United States for all periods presented, with a small portion attributable to customers loca ted in Canada and other countries.
Revenue Recognition	Revenue Recognition The Company derives its revenue from two sources: (1) subscription and services revenue, which is derived primarily from the sale of subscription plans for communications services and other connected services; and (2) product and other revenue. Subscriptions and services are sold directly to end-customers. Products are sold to end-customers through several channels, including but not limited to distributors, retailers and resellers (collectively “channel partners”), and Ooma sales representatives. Under Topic 606, the Company determines revenue recognition through the following steps: • identification of the contract(s) with a customer; • identification of the performance obligations in the contract; • determination of the transaction price; • allocation of the transaction price to the performance obligations in the contract; and • recognition of revenue when, or as, the Company satisfies a performance obligation
Subscription and Service Revenue	Subscription and Services Revenue. Most of the Company’s revenue is derived from recurring subscription fees related to service plans such as Ooma Business, Ooma Residential and other communications services. Service plans are generally sold as monthly subscriptions; however, certain plans are also offered as annual or multi-year subscriptions. Subscription revenue is generally recognized ratably over the contractual service term. A small portion of total revenue is recognized on an over-time basis from installation-related services and on a point-in-time basis from services such as: prepaid international calls, directory assistance, and advertisements displayed through its Talkatone mobile application.
Product and Other Revenue	Product and Other Revenue. Product and other revenue is generated from the sale of on-premise appliances and end-point devices, 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. The Company’s distribution agreements with channel partners typically contain clauses for price protection and right of return. Credits and/or rebates issued for expected product returns and sales incentives are deemed to be variable consideration under Topic 606, which the Company estimates and records as a reduction to revenue at the point of sale. Product returns and customer sales incentives are estimated based on the Company’s historical experience, current trends and expectations regarding future experience. As of January 31, 2021 and 2020, the Company had total reserves for product returns and sales incentives of approximately $1.1 million and $1.4 million, respectively. Revenue is recorded net of any sales and telecommunications taxes collected from customers to be remitted to government authorities. Amounts billed to customers related to shipping and handling are classified as product and other revenue. Shipping and handling costs are expensed as incurred and classified as cost of revenue.
Multiple performance obligations	Multiple performance obligations. The Company’s contracts with customers typically contain multiple performance obligations that consist of product(s) and related communications services. For these contracts, individual performance obligations are accounted for separately if they are distinct. The contract transaction price is then allocated to the separate performance obligations on a relative stand-alone selling price basis. The Company determines the SSP for its communications services based on observable historical stand-alone sales to customers, for which a substantial majority of selling prices must fall within a reasonably narrow pricing range. The Company establishes SSP for its on-premise appliances and end-point devices based upon management’s best estimates and judgments, considering company-specific factors such as pricing strategies, discounting practices, and estimated product and other costs.
Cash Equivalents and Short-term Investments	Cash Equivalents and Short-term Investments. All highly liquid investments with an original maturity of three months or less at the date of purchase are classified as cash equivalents. Short-term investments are classified as available-for-sale and carried at fair value, with unrealized gains and losses, net of tax, recorded as a separate component of stockholders’ equity within accumulated other comprehensive income. The cost of securities sold is based upon the specific identification method.
Fair Value of Financial Instruments	Fair Value of Financial Instruments. The Company records its financial assets and liabilities at fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the reporting date. The Company estimates and categorizes the fair value of its financial assets 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 Transfers among Level classifications are recognized as of the actual date of the events or change in circumstances that caused the transfers. The carrying value of the Company’s financial instruments, including cash equivalents, accounts receivable, inventory, accounts payable and other current assets and current liabilities approximates fair value due to their short maturities.
Concentration of Credit Risk	Concentration of Credit Risk. Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash equivalents, short-term investments, accounts receivable and convertible note receivable. The Company’s cash equivalents and short-term investments are held by financial institutions that management believes are of high-credit quality. Such investments and deposits may, at times, exceed federally insured limits. The Company performs credit evaluations of its channel partners’ financial condition and generally does not require collateral for sales made on credit. As of January 31, 2021, one customer accounted for 10% of the Company’s net accounts receivable balance. As of January 31, 2020, no single customer accounted for 10% or more of the Company’s net accounts receivable balance.
Accounts Receivable	Accounts Receivable. Accounts receivable are recorded net of an allowance for doubtful accounts for estimated credit losses. Allowances are recorded based upon the Company’s assessment of several factors, including historical experience, aging of receivable balances and economic conditions. As of January 31, 2021 and 2020, the allowance for doubtful accounts was $0.3 million and $0.2 million, respectively. Bad debt expense recorded in the consolidated statement of operations was not material for the periods presented.
Inventories	Inventories. Inventories, which consist of raw materials and finished goods, include the cost to purchase manufactured products, allocated labor and overhead. Inventories are stated at the lower of actual cost or market on a first-in, first-out basis. The Company’s assessment of market value requires the use of estimates regarding the net realizable value of its inventory balances, including management’s assessment of excess or obsolete inventory based upon forecast demand and market conditions. Adjustments to reduce inventory to net realizable value are recognized as a component of cost of revenue in the consolidated statement of operations.
Customer Acquisition Costs	Customer Acquisition Costs. Sales commissions and other costs paid to internal sales personnel, third-party sales entities and value-added resellers are considered incremental and recoverable costs of obtaining customer contracts. (The resellers are selling agents for the Company and earn sales commissions that are directly tied to the value of the contracts that the Company enters with the end-user customers.) In accordance with Topic 606, these costs are capitalized and amortized on a systematic basis over the expected period of benefit of five years, or customer contractual term for multi-year contracts, calculated based on both qualitative and quantitative factors, such as expected subscription term and expected renewal periods of its customer contracts, product life cycles and customer attrition. Amortization expense is recorded in sales and marketing expenses in the consolidated statement of operations. The Company pays sales commissions on initial contracts and contracts for increased purchases with existing customers (expansion contracts) and does not pay commissions for contract renewals. The Company periodically evaluates whether there have been any changes in its business, the market conditions in which it operates or other events which would indicate that its amortization period should be changed or if there are potential indicators of impairment. To date, there have been no material impairment losses related to the costs capitalized.
Internal-Use Website Development Costs	Internal-Use Website Development Costs. The Company capitalizes certain costs to develop its websites when preliminary development efforts are successfully completed, management has authorized and committed project funding, and it is probable that the project will be completed and the software will be used as intended. Such costs primarily include payroll-related costs for engineers and contractors directly associated with the development project. Capitalized website development costs are included in property and equipment and are amortized on a straight-line basis over an estimated useful life of two years. Costs related to preliminary project activities and post-implementation activities are expensed as incurred.
Property and Equipment, net	Property and Equipment, net. Property and equipment, net is stated at cost, less accumulated depreciation and amortization. Depreciation and amortization is computed on a straight-line basis over the estimated useful lives of those assets, generally two to five years. Leasehold improvements are amortized over the shorter of the lease term or estimated useful lives of the respective assets. Repairs and maintenance costs that do not extend the life or improve the asset are expensed as incurred.
Operating Leases	Operating Leases. The Company determines if an arrangement is a lease at inception. The Company’s leases primarily consist of real property and are classified as operating leases. The Company does not have any finance leases nor material arrangements as a lessor. Right-of-use lease assets and lease liabilities are recognized at the lease commencement date based upon the present value of the remaining lease payments over the lease term. The Company uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. Lease expense for lease payments is recognized on a straight-line basis over the term of the lease. Lease terms may include options to renew or extend when it is reasonably certain that the option will be exercised. Lease agreements that contain both lease and non-lease components are accounted for as a single component. Short-term leases with an initial term of twelve months or less are not recorded on the balance sheet. Financial results and disclosure requirements for reporting periods beginning after February 1, 2019 are presented under Topic 842, while prior period amounts have not been adjusted and continue to be reported under Topic 840.
Goodwill	Goodwill. Goodwill represents the excess of the purchase price over the fair value of the net assets acquired in a business combination. Goodwill is evaluated for impairment annually in the fourth quarter of its fiscal year, or more frequently if indicators of potential impairment arise. The Company has a single reporting unit and consequently evaluates goodwill for impairment based on an evaluation of the fair value of the Company as a whole. No impairment has been recognized for any of the periods presented.
Intangible Assets	Intangible Assets. Acquired intangible assets other than goodwill, which primarily consist of developed technology and customer relationships, are amortized over their useful lives unless the lives are determined to be indefinite. For intangible assets acquired in a business combination, the estimated fair values of the assets received are used to establish their recorded values. Valuation techniques consistent with the market approach, income approach and/or cost approach are used to measure fair value.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets. Long-lived assets, such as property and equipment, capitalized website development costs, and intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the fair value of the asset. During fiscal 2020, the Company recorded impairment charges of $0.7 million to cost of product revenue for abandoned developed technology and trade names associated with the Ooma Smart Cam, which was acquired through the fiscal 2018 acquisition of Butterfleye, Inc. and discontinued in October 2019. The Company did not record any material impairment charges for fiscal 2021 or fiscal 2019.
Research and Development	Research and Development. Research and development costs are charged to operating expenses as incurred in the consolidated statements of operations, except for internal-use website development costs that qualify for capitalization, as per above. Research and development expenses consist primarily of personnel-related costs for employees and contractors, including stock-based compensation, as well as license and product certification fees, and allocated costs of facilities and information technology.
Advertising	Advertising. Advertising costs are included in sales and marketing and expensed as incurred, except for production costs associated with television and radio advertising, which are expensed on the first date of airing. Advertising costs were $12.2 million, $13.6 million and $13.7 million for fiscal 2021, 2020 and 2019, respectively. Advertising payments to the Company’s channel partners recorded as a reduction in revenue totaled $0.3 million, $0.4 million and $0.3 million for fiscal 2021, 2020 and 2019, respectively.
Stock-Based Compensation	Stock-Based Compensation. Stock-based compensation expense for all stock-based awards granted to employees and non-employee directors is measured at the grant date fair value of the equity award. The fair value of options granted and purchase rights under the Company’s ESPP are estimated on the date of grant using the Black-Scholes pricing model. The fair value of each RSU granted is determined using the fair value of the Company’s common stock on the date of grant. Compensation expense is recognized using the straight-line method over the requisite service period, which is generally the vesting period. Forfeitures are recorded in the period in which they occur.
Income Taxes	Income Taxes. Income taxes are recorded using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income (loss) in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. A tax position is recognized when it is more-likely-than-not that the tax position will be sustained upon examination, including resolution of any related appeals or litigation processes. A tax position that meets the more likely than not recognition threshold is measured at the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement with a taxing authority. Interest and penalties associated with unrecognized tax benefits are classified as income tax expense. The Company had no interest or penalty accruals associated with uncertain tax benefits in its consolidated balance sheets and statements of operations for any periods presented.
Foreign Currency	Foreign currency. The U.S. dollar is the functional currency of the Company's foreign subsidiaries. Remeasurement and transaction gains and losses are included in interest and other income, net and were not material for any periods presented.
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 were 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 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.
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 as well as clarifies and amends existing guidance to improve consistent application. The Company is adopting the new guidance on February 1, 2021 and does not expect the adoption to have a material impact on its consolidated financial statements.

Credit agreement initiation date	Jan. 8, 2021
Maximum borrowing capacity	$ 45,000,000
Borrowing capacity description			On January 8, 2021, the Company, as borrower, entered into a credit and security agreement (the “Credit Agreement”) with KeyBank National Association as Administrative Agent (the “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 million, which includes a $10 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.
Credit agreement, Interest rate description			Loans under the Credit Agreement will bear interest, at the Company’s option, at either a rate equal to the “Base Rate” (as defined in the Credit Agreement) or (b) “Eurodollar Rate” (as defined in the Credit Agreement) plus 2.50%.  The Base Rate is the highest of (i) the Agent’s prime rate, (ii) the federal funds effective rate plus 0.5%, and (iii) the Eurodollar Rate with an interest period of one month plus 1%. The Eurodollar Rate is the London Interbank Offered Rate with various interest periods as may be selected by the Company but shall not be less than 0.75%.  Upon the occurrence of any event of default, the interest rate on any borrowings increases by 2.0%. The Credit Agreement also contains customary provisions for the replacement of the London Interbank Offered Rate/Eurodollar Rate.  The Company is required to pay a commitment fee on the unused portion of the Credit Facility of 0.25% per annum.
Percentage of commitment fees on revolving credit facility	0.25%
Credit agreement expiration date	Jan. 7, 2024
Credit agreement expiration description			The Credit Agreement will terminate and all amounts owing thereunder will be due and payable on the earlier of January 7, 2024 or 90 days prior to the scheduled maturity of any convertible debt securities, unless the commitments are terminated earlier, either at the request of the Company or, if an event of default occurs, by the lenders (or automatically in the case of certain bankruptcy-related events).
