Accounting Policies [Abstract] | |
Description of Business and Summary of Significant Accounting Policies | 1. Description of Business and Summary of Significant Accounting Policies Description of Business Ooma, Inc. (the “Company”) is a leading provider of innovative communications solutions and other connected services to small business, home, and mobile users. The Company’s unique hybrid Software-as-a-Service (“SaaS”) platform, consisting of its proprietary cloud, on-premises appliances, mobile applications, and end-point devices, provides the connectivity and functionality that enables solutions. The Company’s communications solutions deliver its proprietary high-definition (“HD”) voice quality, advanced features, and integration with mobile devices, at extremely competitive pricing and value. The Company’s platform helps create smart workplaces and homes by providing value-added communications and other connected services and by integrating end-point devices to enable the Internet of Things. The Company’s platform and solutions have the power to provide communications, productivity, automation, monitoring, safety, security, and networking infrastructure applications to our users. The Company was incorporated in Delaware on November 19, 2003 and is headquartered in Palo Alto, California. Basis of Presentation 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 consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the year ended January 31, 2017. 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 the Company’s condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Significant estimates include, but are not limited to, those related to revenue recognition, the allowance for returns, stock-based compensation, valuation of goodwill and intangible assets, inventory valuation, regulatory fees and indirect tax accruals, accounting for income taxes including valuation allowances and fair value measurements. Estimates are based on historical experience, where applicable, and other assumptions believed to be reasonable by management. Actual results could differ from those estimates. 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. Concentration of Risk The concentration of accounts receivable as of April 30, 2017 and January 31, 2017, respectively are as follows: As of April 30, 2017 January 31, 2017 Customer A 12% * Customer B * 11% * Represented less than 10% of accounts receivable, net at the end of respective periods There were no customers that individually exceeded 10% of revenue during the three months ended April 30, 2017 and 2016. Secondary Offerings In January 2017 and March 2017, the Company completed two secondary offerings, in which certain stockholders of the Company affiliated with Worldview Technology Partners (the “Selling Stockholders”) sold an aggregate of 3,275,000 shares and 3,290,483 Worldview Technology Partners owned less than 1% of the Company’s outstanding voting securities. Summary of Significant Accounting Policies There have been no material changes to the Company's significant accounting policies as described in its Annual Report on Form 10-K for the year ended January 31, 2017. Recently Adopted Accounting Standard In August 2014, the Financial Accounting Standards Board (“FASB”) issued ASU 2014-15 (ASC 205) , Disclosure of Uncertainties About an Entity’s Ability to Continue as a Going Concern Recent Accounting Pronouncements Not Yet Adopted In January 2017, the FASB issued ASU 2017-04, Intangibles – Goodwill and Other (Topic 350) In February 2016, the FASB issued ASU 2016-02, Leases In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers In August 2015, the FASB issued ASU 2015-14 and approved a one-year deferral of the effective date of ASU 2014-09. In March 2016, April 2016 and May 2016, the FASB issued ASU 2016-08, ASU 2016-10 and ASU 2016-12, respectively that clarify the implementation guidance on principal versus agent considerations, identification of performance obligations, collectability criterion and noncash consideration of the new standard. ASU 2014-09 will become effective for the Company in the first quarter of fiscal 2019. Early adoption is permitted and the new standard can be adopted by using (i) a full retrospective approach for all periods presented in the period of adoption or (ii) a modified retrospective approach with the cumulative effect of initially applying the new standard recognized at the date of initial application and providing certain additional disclosures. The Company does not plan to early adopt the new standard. The Company is in the early stages of evaluating the impact of the new standard on its accounting policies, processes, and system requirements and has not made a final decision regarding the adoption method. The Company's final determination will depend on a number of factors, such as the significance of the impact of the new standard on its financial results, system readiness, including that of software procured from third-party providers, and its ability to accumulate and analyze the information necessary to assess the impact on prior period financial statements, as necessary. While the Company continues to assess the potential impacts of the new standard, the Company cannot reasonably estimate quantitative information related to the impact of the new standard on its financial statements at this time. |

Fair Value Disclosures [Abstract] | |
Fair Value Measurement | 2. Fair Value Measurement The Company records its financial assets and liabilities at fair value. The inputs used in the valuation methodologies in measuring fair value are defined in the fair value hierarchy as follows: Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for identical assets or liabilities. Level 2: Observable prices that are based on inputs not quoted on active markets, but corroborated by market data. Level 3: Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities and which reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model. The Company’s financial instruments consisted of Level 1 and Level 2 assets as of April 30, 2017 and January 31, 2017. There were no transfers into or out of the Level 3 category during the three months ended April 30, 2017. The Company’s financial assets that are measured at fair value on a recurring basis by level within the fair value hierarchy were as follows (in thousands): As of April 30, 2017 Level 1 Level 2 Total Assets: Cash and cash equivalents: Money market funds $ 4,488 $ — $ 4,488 U.S. agency securities — 1,498 1,498 Total cash equivalents $ 4,488 $ 1,498 $ 5,986 Cash 3,022 Total cash and cash equivalents $ 9,008 Short-term investments: U.S. government securities $ 13,886 $ — $ 13,886 Corporate debt securities — 18,834 18,834 Commercial paper — 4,442 4,442 U.S. agency securities — 5,747 5,747 Asset-backed securities — 1,358 1,358 Total short-term investments $ 13,886 $ 30,381 $ 44,267 As of January 31, 2017 Level 1 Level 2 Total Assets: Cash and cash equivalents: Money market funds $ 951 $ — $ 951 Total cash equivalents $ 951 $ — $ 951 Cash 3,039 Total cash and cash equivalents $ 3,990 Short-term investments: U.S. government securities $ 17,798 $ — $ 17,798 Corporate debt securities — 18,436 18,436 Commercial paper — 5,386 5,386 U.S. agency securities — 5,777 5,777 Asset-backed securities — 1,814 1,814 Total short-term investments $ 17,798 $ 31,413 $ 49,211 The carrying value of the Company’s accounts receivable, inventory, accounts payable and other current assets and current liabilities approximates fair value due to short maturities. |

The cost basis and fair value of the short-term investments by contractual maturity were as follows (in thousands): As of April 30, 2017 As of January 31, 2017 Amortized Value Fair Value Amortized Value Fair Value One year or less $ 40,275 $ 40,253 $ 44,806 $ 44,794 Over one year and less than two years 4,015 4,014 4,416 4,417 Total $ 44,290 $ 44,267 $ 49,222 $ 49,211 Investments in an unrealized loss position consisted of the following (in thousands): As of April 30, 2017 As of January 31, 2017 Fair Value Unrealized Losses Fair Value Unrealized Losses Corporate debt securities $ 18,834 $ (14 ) $ 18,436 $ (20 ) U.S. government securities 13,886 (9 ) 17,798 (2 ) U.S. agency securities 5,747 (2 ) 5,777 — Total $ 38,467 $ (25 ) $ 42,011 $ (22 ) The Company reviews the individual securities in its portfolio to determine whether a decline in a security’s fair value below the amortized cost basis is other-than-temporary. The Company determined that as of April 30, 2017 and January 31, 2017, there were no investments in its portfolio that were other-than-temporarily impaired. The Company does not intend to sell any of these investments, and it is not more likely than not that the Company would be required to sell these investments before recovery of their amortized cost basis, which may be at maturity. |

Commitments And Contingencies Disclosure [Abstract] | |
Commitments and Contingencies | 5. Commitments and Contingencies Leases and Purchase Commitments The Company leases office space in Palo Alto and Newark, California under operating leases. As of April 30, 2017, the Company had $1.0 million outstanding under operating leases with lease periods expiring through November 2020. In January 2015, the Company entered into a capital lease for computer equipment that was scheduled to mature in December 2016 with the right to purchase the equipment at maturity for one dollar. The Company repaid the outstanding balance of $0.6 million in April 2016. Total interest expense recognized was $18,000 for the three months ended April 30, 2016. Rent expense was $0.4 million and $0.5 million for the three months ended April 30, 2017 and 2016, respectively. As of April 30, 2017, non-cancelable purchase commitments were $3.5 million. Legal Proceedings Oregon 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 starting on January 1, 2013 and ending on March 31, 2016 (collectively, the “Assessments”). On November 28, 2016 the Company filed a complaint in the Oregon Tax Court, asserting that the Assessments against Ooma are in violation of applicable Oregon law and are barred by the United States Constitution, and asking the Oregon Tax Court to abate the Assessments in full (the “Complaint”, and such dispute, the “Oregon Tax Litigation”). On February 10, 2017, the DOR filed an answer to the Compliant, and during April of 2017 the Company voluntarily participated in an informal discovery process by providing certain information and documents to the DOR. Deep Green Wireless Litigation On June 8, 2016, plaintiff Deep Green Wireless LLC 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 Litigation”). The complaint seeks unspecified monetary damages, costs, attorneys’ fees and other appropriate relief. On July 29, 2016 the Company filed its answer, affirmative defenses and counterclaims, on August 2, 2016 the Company filed a motion to transfer the case to the Northern District of California, and on February 21, 2017 magistrate judge Roy S. Payne granted the Company’s motion to transfer the case. District Court Judge Jeffrey S. White of the Northern District of California set the initial case management conference for July 28, 2017. Based upon its investigation, the Company does not believe that its products infringe any valid or enforceable claim of the aforementioned patent, and plans to continue vigorously defending against the plaintiff’s claim. Securities Litigation On January 14, 2016, Michael Barnett filed a purported stockholder class action in the San Mateo County Superior Court of the State of California (Case No. CIV536959) against Ooma, certain of its officers and directors, and certain of the underwriters of our Initial Public Offering on July 17, 2015 (the “IPO”). Since that time two additional purported class actions making substantially the same allegations against the same defendants were filed, and on May 18, 2016 all three complaints were combined into a “consolidated complaint” filed in the same court (the “Securities Litigation”). The consolidated complaint purports to be brought on behalf of all persons who purchased shares of common stock in our IPO in reliance upon the Registration Statement and Prospectus the Company filed with the Securities and Exchange Commission (the “SEC”). The consolidated complaint alleges that Ooma and the other defendants violated the Securities Act of 1933, as amended (the “Securities Act”) by issuing the Registration Statement and Prospectus, which the plaintiffs allege contained material misstatements and omissions in violation of Sections 11, 12(a)(2) and 15 of the Securities Act. The plaintiffs seek class certification, compensatory damages, attorneys’ fees and costs, rescission or a rescissory measure of damages, equitable and/or injunctive relief, and such other relief as the court may deem proper. On July 1, 2016 Ooma filed its answer to the complaint, and on August 26, 2016 Ooma filed a motion for judgment on the pleadings. Ooma believes that the plaintiffs’ claims are without merit and is vigorously defending against the Securities Litigation. Berks County Litigation On January 21, 2016 the County of Berks, Pennsylvania filed a lawsuit in the Berks County Court of Common Pleas naming the Company and 113 other telephone service providers as defendants (the “Berks County Litigation”), alleging breach of fiduciary duty, fraud, and negligent misrepresentation in connection with alleged violations of the Pennsylvania 911 Emergency Communication Services Act, 35 Pa.C.S.A. §5301 et seq. (“PA 911 Act”) for failure to collect from subscribers and remit certain fees pursuant to the PA 911 Act. The plaintiff seeks a declaratory judgment that we must comply with the PA 911 Act, compensatory and punitive damages, attorneys’ fees and costs, equitable and/or injunctive relief and such other relief as the court may deem proper. On May 17, 2016 the court issued an order overruling the defendants’ joint preliminary objections, which are, in essence, the Pennsylvania equivalent of a motion to dismiss. Notwithstanding such adverse order, the Company believes that the Commerce Clause of the United States Constitution bars the application of the PA 911 Act to the Company, since the Company has no employees, property or other indicia of a “substantial nexus” with the State of Pennsylvania, and therefore the plaintiff’s claims are without merit. The Company intends to continue vigorously defending this lawsuit. The Company is party to actions and proceedings incident to the Company’s business in the ordinary course of business, including litigation regarding its intellectual property, challenges to the enforceability or validity of its intellectual property, and claims that the Company’s products or services infringe on the intellectual property rights of others. The Company accrues a liability for such matters when it is probable that future expenditures will be made and such expenditures can be reasonably estimated. In connection with the Oregon Litigation, Deep Green Wireless Litigation, Securities Litigation and Berks County Litigation, the Company has determined that the amount of any material loss or range of any material losses that is reasonably possible to result from each such proceeding is not reasonably estimable. Accordingly, no material reserves have been recorded in the Company’s condensed consolidated financial statements with respect to any of such litigations. 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 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 consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the year ended January 31, 2017. 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 the Company’s condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Significant estimates include, but are not limited to, those related to revenue recognition, the allowance for returns, stock-based compensation, valuation of goodwill and intangible assets, inventory valuation, regulatory fees and indirect tax accruals, accounting for income taxes including valuation allowances and fair value measurements. Estimates are based on historical experience, where applicable, and other assumptions believed to be reasonable by management. Actual results could differ from those estimates. 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. |

ASU 2014-09 will become effective for the Company in the first quarter of fiscal 2019. Early adoption is permitted and the new standard can be adopted by using (i) a full retrospective approach for all periods presented in the period of adoption or (ii) a modified retrospective approach with the cumulative effect of initially applying the new standard recognized at the date of initial application and providing certain additional disclosures. The Company does not plan to early adopt the new standard. The Company is in the early stages of evaluating the impact of the new standard on its accounting policies, processes, and system requirements and has not made a final decision regarding the adoption method. The Company's final determination will depend on a number of factors, such as the significance of the impact of the new standard on its financial results, system readiness, including that of software procured from third-party providers, and its ability to accumulate and analyze the information necessary to assess the impact on prior period financial statements, as necessary. While the Company continues to assess the potential impacts of the new standard, the Company cannot reasonably estimate quantitative information related to the impact of the new standard on its financial statements at this time. |
