Organization Consolidation And Presentation Of Financial Statements [Abstract] | |
Nature of Operations | 1. Nature of Operations Restoration Robotics, Inc. is a medical technology company incorporated in the state of Delaware on November 22, 2002 and headquartered in San Jose, California. The Company develops an image-guided robotic system that enables follicular unit extraction (FUE) for use in the field of hair transplantation and markets the ARTAS ® Initial Public Offering On October 11, 2017, the Company’s Registration Statement on Form S-1 (File No. 333-220303) relating to the initial public offering (IPO) of its common stock was declared effective by the Securities and Exchange Commission (SEC). Pursuant to such Registration Statement, the Company completed its IPO of 3,897,910 shares of its common stock (inclusive of 322,910 shares of common stock from the subsequent exercise of the over-allotment option granted to the underwriters) at a price of $7.00 per share for aggregate cash proceeds of approximately $22,114, after deducting underwriting discounts and commissions, and offering costs totaling $5,171. Immediately prior to the closing of the IPO, all outstanding shares of convertible preferred stock converted into 22,671,601 shares of common stock and all the outstanding convertible preferred stock warrants converted into common stock warrants resulting in the reclassification of our preferred stock warrant liabilities to additional paid-in capital. In addition, the principal and accrued interest on the outstanding Convertible Notes converted into 718,184 shares of common stock. The IPO closed on October 16, 2017. Follow-on Public Offering On August 16, 2018, the Company closed its follow-on public offering of 10,000,000 shares of its common stock, plus 1,500,000 shares of common stock from the subsequent exercise of the over-allotment option granted to the underwriters. The public offering price of the shares sold was $1.50 per share. The Company received aggregate proceeds of approximately $15.6 million from the follow-on offering, after deducting underwriting discounts and commissions and offering costs totaling $1.6 million. The Company intends to use the net proceeds from this offering (including net proceeds from the underwriters’ exercise of their option to purchase additional shares of common stock) to fund expanded commercialization activities in connection with our recently launched ARTAS ® Reverse Stock Split On September 15, 2017, the Company effected a 1-for-10 reverse stock split of its common stock. Upon the effectiveness of the reverse stock split, (i) every 10 shares of outstanding common stock were combined into one share of common stock, (ii) the number of shares of common stock for which each outstanding option to purchase common stock is exercisable was proportionately decreased on a 1-for-10 basis, (iii) the exercise price of each outstanding option to purchase common stock was proportionally increased on a l-for-10 basis, and (iv) the conversion ratio for each share of outstanding preferred stock which is convertible into our common stock was proportionately reduced on a 1-for-10 basis. All of the outstanding common stock share numbers (including shares of common stock into which our outstanding convertible preferred stock shares are convertible), share prices, exercise prices and per share amounts have been adjusted in these consolidated statements, on a retroactive basis, to reflect this l-for-10 reverse stock split for all periods presented. The par value per share and the authorized number of shares of common stock and convertible preferred stock were not adjusted because of the reverse stock split. |

Accounting Policies [Abstract] | |
Summary of Significant Accounting Policies | 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Liquidity These condensed consolidated financial statements are prepared on a going concern basis that contemplates the realization of assets and extinguishment of liabilities in the normal course of business. The Company has incurred net operating losses and negative cash flows from operations since inception. As of September 30, 2018, and December 31, 2017, the Company has an accumulated deficit of $185,231 and $164,487 and, as of such dates, and through the date of this filing, does not have sufficient capital to fund its planned operations. Because of the Company’s recurring losses from operations and negative cash flows, the Company’s independent registered public accounting firm included an explanatory paragraph in its report on the Company’s consolidated financial statements as of, and for the year ended, December 31, 2017 that such factors raise substantial doubt about the Company’s ability to continue as a going concern. To continue its operations, the Company must achieve profitable operations and/or obtain additional financing. Until the Company generates revenue at a level to support its cost structure, the Company expects to continue to incur substantial operating losses and net cash outflows. The Company may never become profitable and even if it does attain profitable operations, it may not be able to sustain profitability or positive cash flows on a recurring basis. The Company will need to raise further capital in the future to service its debt or fund its operations until the time it can sustain positive cash flows. There can be no assurance that the Company will be successful in raising additional capital or that such capital, if available, will be on terms that are acceptable to the Company. If the Company is unable to raise sufficient additional capital, it may be compelled to reduce the scope of its operations and planned capital expenditures or sell certain assets, including intellectual property assets. The accompanying condensed consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business, and, as such, the condensed consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or amounts and classification of liabilities that might be necessary should the Company be unable to continue in existence. Basis of Presentation The condensed consolidated balance sheet as of September 30, 2018, the condensed consolidated statements of operations and condensed consolidated statements of comprehensive loss for the three and nine months ended September 30, 2018 and 2017 and the condensed consolidated statements of cash flows for the nine months ended September 30, 2018 and 2017 and the condensed consolidated statement of stockholders’ equity for the nine months ended September 30, 2018 are unaudited. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (U.S. GAAP) and in the opinion of management, reflect all adjustments of a normal and recurring nature that are necessary for the fair presentation of the Company’s condensed consolidated financial statements included in this report. The condensed consolidated financial data disclosed in these notes to the condensed consolidated financial statements related to the three- and nine-month periods are also unaudited. The condensed consolidated results of operations for the three and nine months ended September 30, 2018 are not necessarily indicative of the results to be expected for the year ending December 31, 2018, or for any other future annual or interim period. The consolidated balance sheet as of December 31, 2017 included herein was derived from the audited consolidated financial statements as of that date. These condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements included in its Annual Report filed on Form 10-K for the year ended December 31, 2017, with the SEC on March 5, 2018. Principles of Consolidation The accompanying condensed c n s l i a e f i a c i a s t m n i c l u t u Restoration Robotics, Inc. A l i e rc m a n cc u n t r a s c i o a v b e l i m i a i o s l i a t i n Use of Estimates The preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Significant estimates and assumptions made in the accompanying condensed consolidated financial statements include, but are not limited to revenue recognition, the fair value of common stock, and the recoverability of the Company’s net deferred tax assets and related valuation allowance. The Company evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors and adjusts those estimates and assumptions when facts and circumstances dictate. Actual results could materially differ from those estimates. Reclassification Accrued compensation, which were previously included in other accrued liabilities in the prior year's condensed consolidated balance sheet have been reclassified to conform to the current period's presentation. The reclassification had no impact on the previously reported consolidated financial statements for the year ended December 31, 2017. Concentration of Customers For the three and nine months ended September 30, 2018, no customers accounted for more than 10% of the Company’s revenue. For the three months ended September 30, 2017, two customers accounted for 11% and 12% of the Company’s revenues and no customers accounted for more than 10% of the Company’s revenue for the nine months ended September 30, 2017. As of September 30, 2018, no customers accounted for more than 10% of the Company’s accounts receivable. As of December 31, 2017, two customers accounted for 10% and 11% of the Company’s accounts receivable. JOBS Act Accounting Election The Company is an emerging growth company, as defined in the Jumpstart Our Business Startups Act of 2012 (the JOBS Act). Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued after the enactment of the JOBS Act until those standards apply to private companies. The Company has elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date that it is (i) no longer an emerging growth company or (ii) affirmatively and irrevocably opt out of the extended transition period provided in the JOBS Act. As a result, these condensed consolidated financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates. Recently Issued Accounting Standards Not Yet Adopted In May 2014, the Financial Accounting Standards Board (FASB) issued ASU No. 2014‑09, Revenue from Contracts with Customers In February 2016, the FASB issued ASU No. 2016‑02, Leases (Topic 842) |

Earnings Per Share [Abstract] | |
Net Loss per Share | 3. NET LOSS PER SHARE Net Loss Per Share Basic net loss per share is calculated by dividing net loss by the weighted-average number of common shares outstanding during the period, without consideration for common stock equivalents. Diluted net loss per share is computed by dividing net loss by the weighted-average number of common share equivalents outstanding for the period determined using the treasury-stock method. For purposes of this calculation, convertible preferred stock, preferred stock warrants and stock options are common stock equivalents and are only included in the calculation of diluted net loss per share when their effect is dilutive. The following outstanding shares of common stock equivalents were excluded from the calculation of diluted net loss per share attributable to common stockholders for the periods presented because including them would have been antidilutive: As of September 30, 2018 2017 Options to purchase common stock 2,026,889 1,912,644 Convertible preferred stock — 22,671,601 Warrants for preferred stock — 385,126 Warrants for common stock 468,181 — Total potential dilutive shares 2,495,070 24,969,371 |

Fair Value Measurements | 4. FAIR Cash and cash The Company’s lease obligation, term loan and Convertible Notes have fair values that approximate their carrying value. U.S. condensed consolidated condensed consolidated Observable Level - Quoted prices are available in active markets for identical assets or liabilities as of the report date. A quoted price for an identical asset or liability in an active market provides the most reliable fair value measurement because it is directly observable to the market. Level - Pricing inputs are other than quoted prices in active markets, which are either directly or indirectly observable as of the report date. The nature of these securities includes investments for which quoted prices are available but traded less frequently and investments that are fair valued using other securities, the parameters of which can be directly observed. Level - Securities that have little to no pricing observability as of the report date. These securities are measured using management’s best estimate of fair value, where the inputs into the determination of fair value are not observable and require significant management judgment or estimation.

In July 2006, the Company entered into a license agreement with HSC Development, LLC for exclusive non-transferable, royalty-free worldwide rights for use in approved fields relating to a computer-controlled system in which a device is carried on a mechanized arm for extraction or implantation of a follicular unit without manual manipulation. In consideration for this license, the Company paid HSC Development, LLC a one-time payment of $25 and issued 2,500 shares of the Company’s common stock. The agreement terminates on July 27, 2024. Legal Proceedings From time to time the Company is involved in litigation arising out of claims in the normal course of business. Based on the information presently available, management believes that there are no claims or actions pending or threatened against us, the ultimate resolution of which will have a material effect on our financial position, liquidity or results of operations, although the results of litigation are inherently uncertain. Purported Shareholder Class Action On May 23, 2018, a putative shareholder class action complaint was filed in Superior Court of the State of California, County of San Mateo (the “Superior Court”), captioned Wong v. Restoration Robotics, Inc., et al., No. 18CIV02609. On June 21, 2018 and June 28, 2018, two putative class action complaints were filed in the United States District Court for the Northern District of California, captioned Guerrini v. Restoration Robotics, Inc., et al., No. 5:18-cv-03712-EJD and Yzeiraj v. Restoration Robotics, Inc., et al., No. 5:18-cv-03883-BLF, respectively. On July 24, 2018, the U.S. Northern District Court related the Guerrini and Yzeiraj actions and reassigned the Yzeiraj action to Judge Edward J. Davila. The Wong and Guerrini complaints name the Company as defendants, and certain of its current and former executive officers and directors, certain of its venture capital investors and the underwriters in the Company’s IPO. The Yzeiraj complaint names the Company as defendants and certain of its current and former executive officers and directors. The Wong complaint asserts claims under Sections 11, 12(a)(2) and 15 of the Securities Act of 1933, or the Securities Act. The Guerrini and Yzeiraj complaints assert claims under Sections 11 and 15 of the Securities Act. The complaints all allege, among other things, that the Company’s Registration Statement filed with the SEC on September 1, 2017 and the Prospectus filed with the SEC on October 13, 2017 in connection with the Company’s IPO were inaccurate and misleading, contained untrue statements of material facts, omitted to state other facts necessary to make the statements made not misleading and omitted to state material facts required to be stated therein. The complaints seek unspecified monetary damages, other equitable relief and attorneys’ fees and costs. On August 8, 2018, the Company, along with certain of its current and former executive officers and directors, filed a motion to dismiss the Wong complaint based on the forum selection clause designating the federal district courts as the exclusive forum for claims arising under the Securities Act contained in the Company’s Amended and Restated Certificate of Incorporation, and which asked the court in the alternative to stay the Wong action. Also, on August 8, 2018, the venture capital investor and underwriters’ defendants in the Wong action filed demurrers to the Wong complaint, and the Company, along with certain of its current and former executive officers and directors, joined in the venture capital investor defendants’ demurrer. A hearing on the Company’s motion to dismiss and the demurrers to the Wong complaint was held on October 24, 2018. The Company is unable to predict the date on which the Superior Court will issue any decision at this time. On October 2, 2018, the U.S. Northern District Court granted a Motion for Consolidation of Related Actions, Appointment as Lead Plaintiff and Approval of Lead Counsel filed by Plaintiff Edgardo Guerrini, which consolidated the Guerrini and Yzeiraj actions under the caption In re Restoration Robotics, Inc. Securities Litigation, Case No. 5:18-cv-03712-EJD. The U.S. Northern District Court has set an initial hearing for January 24, 2019. The Company believes that these lawsuits are without merit and management intends to vigorously defend against these claims. |

Debt Disclosure [Abstract] | |
Long-Term Debt | 7. LONG-TERM Loan and Security Agreement In May 2018, the Company entered into a Loan and Security Agreement (the Solar Agreement) with Solar Capital Ltd. (Solar) and certain other lenders thereunder (together with Solar, the Lenders), and Solar, as the Collateral Agent. The Solar Agreement consists of a four-year term loan for an aggregate principal amount of $20,000 (the Borrowings), for working capital, to fund the Company’s general business requirements and to repay indebtedness of the Company to Oxford Finance LLC (the Oxford Agreement). The Company used $10,085 of the loan proceeds to repay the outstanding principal of $8,667, a final payment fee of $1,300 plus accrued interest and prepayment fees of $118 under the Oxford Agreement. The Borrowings under the Solar Agreement bear interest through maturity at a rate equal to the U.S. Dollar LIBOR rate plus 7.95% per annum (the Interest Rate). The outstanding balance on the loan was $20,000 and accrued interest totaled $168 as of September 30, 2018. The Interest Rate was 10.1% at September 30, 2018. Pursuant to the terms of the Solar Agreement, the Company shall make interest only payments until December 1, 2019 (the Interest Only Period). The Interest Only Period may be extended up to three additional months, if the Company achieves certain revenue and capital fundraising thresholds. Following cessation of the Interest Only Period, the Company shall make equal monthly payments on the outstanding principal balance of the Borrowings and any unpaid and accrued interest such that the Borrowings shall be fully repaid on May 1, 2022. In addition, pursuant to the Solar Agreement, the Company issued the Lenders warrants (the Warrants) to purchase an aggregate of 161,725 shares of the Company’s common stock, $0.0001 par value per share, at an exercise price of $3.71 per share. The Warrants were immediately exercisable upon issuance, and excluding certain mergers or acquisitions, will expire on the ten-year anniversary of the date of issuance. The fair value of the Warrants issued was determined to be $404 using a Black-Scholes valuation model with the following assumptions: common stock price at issuance of $3.71 per share; exercise price of $3.71; risk-free interest rate of 2.97% based upon observed risk-free interest rates; expected volatility of 55.50% based on the Company’s implied volatility; expected term of ten years, which is the contractual life of the Warrants; and a dividend yield of 0%. The fair value of the Warrants was recorded as a debt discount within notes payable and an increase to additional paid-in capital on the Company’s balance sheet. The debt discount is being amortized as interest expense over the term of the Solar Agreement, using the effective interest method. The third-party transaction costs (not paid directly to the lenders) related to the debt of $404 are accounted for as a debt discount and classified within notes payable on the Company’s balance sheet and amortized as interest expense over the term of the loan using the effective interest method. The obligations under the Solar Agreement are secured by a lien on substantially all the Company’s property, excluding intellectual property. The Solar Agreement contains certain affirmative covenants, negative covenants and events of default, including, covenants and restrictions that among other things, require the Company and its subsidiary to satisfy certain financial covenants including covenants requiring the Company to satisfy certain revenue and liquidity thresholds, and restricts the ability of the Company and its subsidiary’s ability to, incur liens, incur additional indebtedness, make loans and investments, engage in mergers and acquisitions, engage in asset sales or sale and leaseback transactions, and declare dividends or redeem or repurchase capital stock. A failure to comply with these covenants could permit the Lenders under the Solar Agreement to declare the Borrowings, together with accrued but unpaid interest and certain Prepayment Fees, to be immediately due and payable. On November 2, 2018, the Solar Agreement was amended to modify the compliance requirement for certain revenue and liquidity threshold. As part of this amendment, the Company paid a fee of $50 to the Lenders and cancelled 161,725 Warrants (originally issued in May 2018, as mentioned above) and issued 161,725 new warrants of the Company’s common stock, $0.0001 par value per share, at an exercise price of $1.76 per share. All other terms of the Warrants were unchanged. As of September 30, 2018, the Company was in compliance with all covenants under the Solar Agreement, as amended. The Company is also required to make mandatory prepayments of the Borrowings, subject to specified exceptions, upon defaulting on any payments of principal or interest on the Borrowings, the occurrence of certain specified defaults of the covenants in the Solar Agreement, the occurrence of a material adverse change in the business, operations or conditions of the Company and specified other events (each, an Event of Default). Upon the occurrence and continuation of an Event of Default, the Borrowings shall accrue at the Interest Rate plus 4.0%. If all or any of the Borrowings are prepaid or required to be prepaid under the Solar Agreement, then the Company shall pay, in addition to such prepayment, a prepayment premium (the Prepayment Premium) equal to (i) with respect to any such prepayment paid on or prior to May 1, 2019, 3.0% of the principal amount of the Borrowings being prepaid, (ii) with respect to any prepayments paid after May 1, 2019 but on or prior to May 1, 2020, 2.0% of the principal amount of the Borrowings being prepaid and (iii) with respect to any prepayments paid after May 1, 2020 but on or prior to May 1, 2021, 1.0% of the principal amount of the Borrowings being prepaid. Notwithstanding the foregoing, if the Lenders each participate in a refinancing of the Borrowings, then the Prepayment Premium shall be 0%. The scheduled principal payments on the outstanding borrowings as of September 30, 2018 are as follows: As of September 30, 2018 2018 (remaining 3 months) $ — 2019 667 2020 8,000 2021 8,000 2022 4,163 Total 20,830 Less debt discount (1,454 ) Non-current portion $ 19,376 |

The Company granted ISOs and NSOs pursuant to its 2015 Plan until the 2017 Equity Incentive Plan (the 2017 Plan) was approved by the Board of Directors and became effective on October 11, 2017. As a result of the 2017 Plan becoming effective, all remaining shares available for future award under the 2015 Plan were transferred to the 2017 Plan, the 2015 Plan was terminated, and no further grants will be made under the Company’s 2005 Plan and the 2015 Plan. Any outstanding stock awards granted under the 2005 Plan and the 2015 Plan will remain outstanding, subject to the terms of the Company’s 2005 Plan and 2015 Plan and the applicable stock award agreements, until such outstanding stock awards that are stock options are exercised or until they terminate or expire by their terms, or until such stock awards are fully settled, terminated or forfeited. 2017 Plan The Company’s 2017 Plan provides for the grant of ISOs, NSOs, stock appreciation rights, restricted stock awards, restricted stock unit awards, and other forms of equity compensation to employees, directors and consultants.

Income Taxes | 10. INCOME TAXES The Company generated a loss for the three and nine months ended September 30, 2018 and incurred $8 and $32 of tax expense for the three and nine months ended September 30, 2018, respectively. The Company’s effective tax rate is (0.12)% and (0.18)% for income tax for the three and nine months ended September 30, 2018 and the Company expects that its effective tax rate for the full year 2018 will be (0.42)%. Based on available evidence, including cumulative losses since inception and expected future losses, the Company has determined that it is more likely than not that the Company’s U.S. federal, U.S. state and Korea deferred tax assets will not be realized and therefore a valuation allowance has been provided on these net deferred tax assets. The Company has substantial net operating loss carry forwards available to offset future taxable income for U.S. federal and state income tax purposes. The Company’s ability to utilize its net operating losses may be limited due to changes in its ownership as defined by Section 382 of the Internal Revenue Code (the Code). Under the provisions of Sections 382 and 383 of the Code, a change of control, as defined in the Code, may impose an annual limitation on the amount of the Company’s net operating loss and tax credit carryforwards, and other tax attributes that can be used to reduce future tax liabilities. The Company files tax returns for U.S. federal and state tax returns along with tax returns in the United Kingdom, Hong Kong, Spain and South Korea. The Company is not currently subject to any income tax examinations. Since the Company’s inception, the Company had incurred losses from its U.S. operations, which generally allows all tax years to remain open. Beginning in first quarter of 2018, the Company is subject to new provisions of the tax law, including provisions related to Global Low Taxed Intangible Income (GILTI), Foreign Derived Intangible Income deductions (FDII), and other changes. However, due to the Company’s losses and full valuation allowance in the U.S., these were determined to have no material impact to the Estimated Annual Effective Tax Rate due to the full Valuation Allowance in the U.S. Uncertain Tax Positions Effective January 1, 2009, the Company adopted ASC 740-10, which requires that the Company recognize the financial statement effects of a tax position when it becomes more likely than not, based upon the technical merits, that the position will be sustained upon examination. The gross amount of unrecognized tax benefits as of September 30, 2018 is approximately $1,420 and related to the reserve on R&D credits, none of which will affect the effective tax rate if recognized due to the valuation allowance. The Company does not expect any material changes in the next 12 months in unrecognized tax benefits. The Company recognizes interest and/or penalties related to uncertain tax positions. To the extent accrued interest and penalties do not ultimately become payable, amounts accrued will be reduced and reflected in the period that such determination is made. The interest and penalties are recognized as other expense and not tax expense. The Company currently has no interest and penalties related to uncertain tax positions. |

Liquidity | Liquidity These condensed consolidated financial statements are prepared on a going concern basis that contemplates the realization of assets and extinguishment of liabilities in the normal course of business. The Company has incurred net operating losses and negative cash flows from operations since inception. As of September 30, 2018, and December 31, 2017, the Company has an accumulated deficit of $185,231 and $164,487 and, as of such dates, and through the date of this filing, does not have sufficient capital to fund its planned operations. Because of the Company’s recurring losses from operations and negative cash flows, the Company’s independent registered public accounting firm included an explanatory paragraph in its report on the Company’s consolidated financial statements as of, and for the year ended, December 31, 2017 that such factors raise substantial doubt about the Company’s ability to continue as a going concern. To continue its operations, the Company must achieve profitable operations and/or obtain additional financing. Until the Company generates revenue at a level to support its cost structure, the Company expects to continue to incur substantial operating losses and net cash outflows. The Company may never become profitable and even if it does attain profitable operations, it may not be able to sustain profitability or positive cash flows on a recurring basis. The Company will need to raise further capital in the future to service its debt or fund its operations until the time it can sustain positive cash flows. There can be no assurance that the Company will be successful in raising additional capital or that such capital, if available, will be on terms that are acceptable to the Company. If the Company is unable to raise sufficient additional capital, it may be compelled to reduce the scope of its operations and planned capital expenditures or sell certain assets, including intellectual property assets. The accompanying condensed consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business, and, as such, the condensed consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or amounts and classification of liabilities that might be necessary should the Company be unable to continue in existence. |

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (U.S. GAAP) and in the opinion of management, reflect all adjustments of a normal and recurring nature that are necessary for the fair presentation of the Company’s condensed consolidated financial statements included in this report. The condensed consolidated financial data disclosed in these notes to the condensed consolidated financial statements related to the three- and nine-month periods are also unaudited. The condensed consolidated results of operations for the three and nine months ended September 30, 2018 are not necessarily indicative of the results to be expected for the year ending December 31, 2018, or for any other future annual or interim period. The consolidated balance sheet as of December 31, 2017 included herein was derived from the audited consolidated financial statements as of that date.

Use of Estimates | Use of Estimates The preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Significant estimates and assumptions made in the accompanying condensed consolidated financial statements include, but are not limited to revenue recognition, the fair value of common stock, and the recoverability of the Company’s net deferred tax assets and related valuation allowance. The Company evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors and adjusts those estimates and assumptions when facts and circumstances dictate. Actual results could materially differ from those estimates. |

As of September 30, 2018, no customers accounted for more than 10% of the Company’s accounts receivable.

Jobs Act Accounting Election | JOBS Act Accounting Election The Company is an emerging growth company, as defined in the Jumpstart Our Business Startups Act of 2012 (the JOBS Act). Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued after the enactment of the JOBS Act until those standards apply to private companies. The Company has elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date that it is (i) no longer an emerging growth company or (ii) affirmatively and irrevocably opt out of the extended transition period provided in the JOBS Act. As a result, these condensed consolidated financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates. |
