Accounting Policies [Abstract]
Basis of Presentation and Description of Company	Note 1 – Basis of Presentation and Description of Company U.S. Auto Parts Network, Inc. (including its subsidiaries) is a leading online provider of aftermarket auto parts and accessories and was established in 1995. The Company entered the e-commerce sector by launching its first website in 2000 and currently derives the majority of its revenues from online sales channels. The Company sells its products to individual consumers through a network of websites and online marketplaces. Our flagship consumer websites are located at www.autopartswarehouse.com , www.carparts.com , and www.jcwhitney.com and our corporate website is located at www.usautoparts.net . References to the “Company,” “we,” “us,” or “our” refer to U.S. Auto Parts Network, Inc. and its consolidated subsidiaries. The Company’s products consist of collision parts serving the body repair market, engine parts to serve the replacement parts market, and performance parts and accessories. The collision parts category is primarily comprised of body parts for the exterior of an automobile. Our parts in this category are typically replacement parts for original body parts that have been damaged as a result of a collision or through general wear and tear. The majority of these products are sold through our websites. In addition, we sell an extensive line of mirror products, including our own private-label brand called Kool-Vue ® , which are marketed and sold as aftermarket replacement parts and as upgrades to existing parts. The engine parts category is comprised of engine components and other mechanical and electrical parts including our private label brand of catalytic converters called Evan Fischer ® . These parts serve as replacement parts for existing engine parts and are generally used by professionals and do-it-yourselfers for engine and mechanical maintenance and repair. We also offer performance versions of many parts sold in each of the above categories. Performance parts and accessories generally consist of parts that enhance the performance of the automobile, upgrade existing functionality of a specific part or improve the physical appearance or comfort of the automobile. The Company is a Delaware C corporation and is headquartered in Carson, California. The Company has employees located in both the United States and the Philippines. Basis of Presentation The consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial information and with the instructions to U.S. Securities and Exchange Commission (“SEC”) Form 10‑Q and Article 10 of SEC Regulation S-X. In the opinion of management, the accompanying consolidated financial statements contain all adjustments, consisting of normal recurring adjustments, necessary to present fairly the consolidated financial position of the Company as of June 29, 2019 and the consolidated results of operations and cash flows the thirteen and twenty-six weeks ended June 29, 2019 and June 30, 2018. The Company’s results for the interim periods are not necessarily indicative of the results that may be expected for any other interim period, or for the full year. These unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto included in our Annual Report on Form 10‑K for the year ended December 29, 2018, which was filed with the SEC on March 13, 2019 and all our other periodic filings, including Current Reports on Form 8‑K, filed with the SEC after the end of our 2018 fiscal year, and throughout the date of this report. During the thirteen and twenty-six weeks ended June 29, 2019, the Company incurred a net loss of $1,457 and $5,038 respectively, compared to a net loss of $797 and $229 during the thirteen and twenty-six weeks ended June 30, 2018, respectively. Based on our current operating plan, we believe that our existing cash, cash equivalents, investments, cash flows from operations and available debt financing will be sufficient to finance our operational cash needs through at least the next twelve months. Recently Adopted Accounting Pronouncements In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2016 02, “Leases” (“ASU 2016 02”). The objective of this update is to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The new standard became effective for us on January 1, 2019. We recognized a cumulative adjustment of $1,623 to the opening balance of retained earnings as of the adoption date and recognized additional right-of-use (“ROU”) assets and operating lease liabilities on our consolidated balance sheet. Recent Accounting Pronouncements In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2018 15, “Intangibles—Goodwill and Other— Internal-Use Software (Subtopic 350-40)” (“ASU 2018 15”). The objective of this update is to align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The new standard is effective for fiscal years beginning after December 15, 2019, and interim periods within fiscal years beginning after December 15, 2019. Early adoption is permitted. The Company is currently evaluating the effect that ASU 2018 15 will have on the consolidated financial statements and related disclosures.

Borrowings

Borrowings	6 Months Ended

Debt Disclosure [Abstract]
Borrowings	Note 2 – Borrowings The Company maintains an asset-based revolving credit facility ("Credit Facility") that provides for, among other things, a revolving commitment in an aggregate principal amount of up to $30,000, which is subject to a borrowing base derived from certain receivables, inventory, and property and equipment. At June 29, 2019, our outstanding revolving loan balance was $0. The guaranteed total letters of credit balance at June 29, 2019 was $18,071, of which $15,034 was utilized and included in accounts payable in our consolidated balance sheet. Loans drawn under the Credit Facility bear interest, at the Company’s option, at a per annum rate equal to either (a) LIBOR plus an applicable margin of 1.75%, or (b) an “alternate prime base rate” subject to an increase or reduction by up to 0.25% per annum based on the Company’s fixed charge coverage ratio. At June 29, 2019, the Company’s LIBOR based interest rate was 4.19% (on $0 principal) and the Company’s prime based rate was 5.75% (on $0 principal). A commitment fee, based upon undrawn availability under the Credit Facility bearing interest at a rate of 0.25% per annum, is payable monthly. Under the terms of the credit agreement with JP Morgan Chase Bank (the "Credit Agreement"), cash receipts are deposited into a lock-box, which are at the Company’s discretion unless the “cash dominion period” is in effect, during which cash receipts will be used to reduce amounts owing under the Credit Agreement. The cash dominion period is triggered in an event of default or if excess availability is less than the $3,600 for three business days (on a cumulative basis) and will continue until, during the preceding 60 consecutive days, no event of default existed and excess availability has been greater than $3,600 at all times (with such trigger subject to adjustment based on the Company’s revolving commitment). In addition, in the event that “excess availability,” as defined under the Credit Agreement, is less than $2,400, the Company shall be required to maintain a minimum fixed charge coverage ratio of 1.0 to 1.0 (with the trigger subject to adjustment based on the Company’s revolving commitment). The Company’s excess availability was $6,740 at June 29, 2019. As of the date hereof, the cash dominion period has not been in effect; accordingly, no principal payments are due. The Credit Agreement requires us to obtain a prior written consent from JPMorgan Chase Bank when we determine to pay any dividends on or make any distribution with respect to our common stock. The credit facility matures on April 26, 2020.

In addition, 81 share awards were released to two departing board members and 7 shares were issued as partial payment for director’s fee as elected by a Board member. For the RSUs awarded, the number of shares issued on the date of vest is net of the minimum statutory withholding requirements that we pay in cash to the appropriate taxing authorities on behalf of our employees. For those employees who elect not to receive shares net of the minimum statutory withholding requirements, the appropriate taxes are paid directly by the employee. During the twenty-six weeks ended June 29, 2019, we withheld 95 shares to satisfy $ 102 of employees’ tax obligations. Although shares withheld are not issued, they are treated as a common stock repurchase in our consolidated financial statements, as they reduce the number of shares that would have been issued upon vesting. For the thirteen and twenty-six weeks ended June 29, 2019, we recorded compensation costs related to stock options and RSUs of $625 and $1,180, respectively. For the thirteen and twenty-six weeks ended June 30, 2018 we recorded compensation costs related to stock options and RSUs of $ 156 and $1,158, respectively. As of June 29, 2019, there was unrecognized compensation expense related to stock options and RSUs of $4,056.

Income Taxes	Note 5 – Income Taxes The Company is subject to U.S. federal income tax as well as income tax of foreign and state tax jurisdictions. The tax years 2014‑2018 remain open to examination by the major taxing jurisdictions to which the Company is subject, except the Internal Revenue Service for which the tax years 2015‑2018 remain open. For the thirteen and twenty-six weeks ended June 29, 2019 the effective tax rate for the Company’s continuing operations was 11.3% and 8.4%, respectively. The effective tax rate for the thirteen and twenty-six weeks ended June 29, 2019 differed from the U.S. federal statutory rate primarily due to state income taxes, income of our Philippines subsidiary that is subject to different effective tax rates, and share-based compensation that is either not deductible for tax purposes or for which the tax deductible amount is different than the financial reporting amount. The Company accounts for income taxes in accordance with ASC Topic 740 - Income Taxes (“ASC 740”). Under the provisions of ASC 740, management is required to evaluate whether a valuation allowance should be established against its deferred tax assets. As of each reporting date, the Company’s management considers new evidence, both positive and negative, that could impact management’s view with regard to future realization of deferred tax assets. For the twenty-six weeks ended June 29, 2019, there was no material change from fiscal year ended 2018 in the amount of the Company's deferred tax assets that are more likely than not to be realized in future years. For the thirteen and twenty-six weeks ended June 30, 2018, the effective tax rate for the Company’s continuing operations was 11.8% and 793.9%, respectively. The effective tax rate for the thirteen and twenty-six weeks ended June 30, 2018 differed from the U.S. federal statutory rate primarily due to state income taxes, income of our Philippines subsidiary that is subject to different effective tax rates, and share-based compensation that is either not deductible for tax purposes or for which the tax deductible amount is different than the financial reporting amount.

A wholly-owned subsidiary of the Company, Automotive Specialty Accessories and Parts, Inc. and its wholly-owned subsidiary Whitney Automotive Group, Inc. ("WAG"), are named defendants in several lawsuits involving claims for damages caused by installation of brakes during the late 1960’s and early 1970’s that contained asbestos. WAG marketed certain brakes, but did not manufacture any brakes. WAG maintains liability insurance coverage to protect its and the Company’s assets from losses arising from the litigation and coverage is provided on an occurrence rather than a claims made basis, and the Company is not expected to incur significant out-of-pocket costs in connection with this matter that would be material to its consolidated financial statements. Customs Issues. On April 2, 2018, the Company filed a complaint against the United States of America, the United States Department of Homeland Security (“DHS”), Secretary Kirstjen Nielsen, and Chief Frederick Eisler (collectively, the “Defendants”) in the United States Court of International Trade (the “Court”) (Case No. 1:18‑cv‑00068) seeking (i) relief from a single entry bonding requirement set by the United States Customs and Border Protection (“CBP”), an agency of DHS, at a level equivalent to three times the commercial invoice value of each shipment (the “Bonding Requirement”), (ii) a declaration that the Bonding Requirement is unlawful, (iii) an injunction prohibiting additional delayed entry for all of the Company’s currently-held goods being denied entry into the United States by CBP and all of the Company’s future imports, and (iv) recovery of our attorneys’ fees incurred in connection with the action. The genesis for the action is CBP’s wrongful seizure of aftermarket vehicle grilles and associated parts being imported by the Company (“Repair Grilles”) on the basis that the Repair Grilles allegedly bear counterfeit trademarks of the original automobile manufacturers (i.e., original-equipment manufacturers, or “OEMs”). Generally, these trademarks, as applied against the Company, purport to cover the shape of the grilles themselves, or the OEM’s logo or name. However, the Repair Grilles are not counterfeit and do not cause a likelihood of confusion amongst purchasers or the relevant consuming public which are prerequisites for seizures under the pertinent provision of the Tariff Act being relied upon by CBP to seize the Repair Grilles. On May 25, 2018, the Court granted the Company’s motion for preliminary injunction and ordered that (i) the Defendants are restrained from enforcing the 3X Bonding Requirement, the Three Percent Bonding Requirement, and any other enhanced bonding requirement on the Company in order to obtain entry of its shipments into the United States, and (ii) CBP shall use its best efforts to process all of the Company’s shipping containers and release all of the Company’s imports not implicated by CBP’s underlying trademark infringement allegations in a timely manner. The Court’s decision may be appealed by DHS, and no assurance may be given as to the outcome of any such appeal. The Court’s May 25, 2018 decision is described herein in summary fashion only. The full text of the decision should be read in its entirety. Copies of the decision are available on the Court’s electronic filing system (located on the Court’s docket at No. 18‑00068). Despite the favorable court order, the Company continued to experience issues with product flow arising from CBP’s inability to process the Company’s shipping containers in an expeditious fashion. As a result, the Company incurred significant port and carrier fees resulting from the increased period of time the Company’s containers remained at the port. The fees associated with this unreleased product, as well as the increased legal costs associated with the product seizures and the bonding litigation, aggregated to $99 and $365 the thirteen and twenty-six weeks ended June 29, 2019, respectively. On July 24, 2019, the Company reached confidential settlement terms with CBP to settle these matters. As part of the settlement: (i) Customs will release to the Company certain inventory mistakenly seized, (ii) the Company and CBP enter into mutual releases, (iii) without admitting liability, the Company will forfeit to CBP certain goods which CBP deems to be violative. All outstanding CBP enforcement issues are resolved, and the Company has no outstanding damage or duty claims from CBP. All product not implicated by the trademark infringement allegations has been released by CBP. Ordinary course litigation. The Company is subject to legal proceedings and claims which arise in the ordinary course of its business. As of the date hereof, the Company believes that the final disposition of such matters will not have a material adverse effect on the financial position, results of operations or cash flow of the Company. The Company maintains liability insurance coverage to protect the Company’s assets from losses arising out of or involving activities associated with ongoing and normal business operations.

Basis of Presentation	Basis of Presentation The consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial information and with the instructions to U.S. Securities and Exchange Commission (“SEC”) Form 10‑Q and Article 10 of SEC Regulation S-X. In the opinion of management, the accompanying consolidated financial statements contain all adjustments, consisting of normal recurring adjustments, necessary to present fairly the consolidated financial position of the Company as of June 29, 2019 and the consolidated results of operations and cash flows the thirteen and twenty-six weeks ended June 29, 2019 and June 30, 2018. The Company’s results for the interim periods are not necessarily indicative of the results that may be expected for any other interim period, or for the full year. These unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto included in our Annual Report on Form 10‑K for the year ended December 29, 2018, which was filed with the SEC on March 13, 2019 and all our other periodic filings, including Current Reports on Form 8‑K, filed with the SEC after the end of our 2018 fiscal year, and throughout the date of this report. During the thirteen and twenty-six weeks ended June 29, 2019, the Company incurred a net loss of $1,457 and $5,038 respectively, compared to a net loss of $797 and $229 during the thirteen and twenty-six weeks ended June 30, 2018, respectively.

Recently Adopted and Recent Accounting Accounting Pronouncements	Recently Adopted Accounting Pronouncements In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2016 02, “Leases” (“ASU 2016 02”). The objective of this update is to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The new standard became effective for us on January 1, 2019. We recognized a cumulative adjustment of $1,623 to the opening balance of retained earnings as of the adoption date and recognized additional right-of-use (“ROU”) assets and operating lease liabilities on our consolidated balance sheet. Recent Accounting Pronouncements In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2018 15, “Intangibles—Goodwill and Other— Internal-Use Software (Subtopic 350-40)” (“ASU 2018 15”). The objective of this update is to align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The new standard is effective for fiscal years beginning after December 15, 2019, and interim periods within fiscal years beginning after December 15, 2019. Early adoption is permitted.
