Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies Basis of Presentation and Use of Estimates The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany account balances and transactions have been eliminated upon consolidation. The unaudited condensed consolidated financial statements were prepared in accordance with the United States (“U.S.”) Generally Accepted Accounting Principles (“GAAP”) for interim financial information and with the instructions to Quarterly Report on Form 10‑Q and Article 10 of Regulation S-X. As permitted under those rules, certain footnotes or other financial information may be condensed or omitted. The preparation of consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts that are reported in the consolidated financial statements and the related disclosures. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions include, but are not limited to: the useful lives of property and equipment and intangibles, allowance for sales returns, breakage on loyalty points and rewards and gift cards, valuation of inventory, stock-based compensation, lease liabilities, goodwill and acquired intangible assets. In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all normal and recurring adjustments necessary to present fairly the financial position of the Company as of June 30, 2024, and the results of operations and cash flows for the interim periods presented. The accompanying unaudited condensed consolidated financial statements and related financial information should be read in conjunction with the Company’s audited consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 (the “2023 10-K”). Recently Adopted Accounting Pronouncements There were no accounting pronouncements adopted during the three and six months ended June 30, 2024. Accounting Pronouncements Not Yet Effective In October 2023, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2023-06, “Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative,” to amend certain disclosure and presentation requirements for a variety of topics within the Accounting Standards Codification (the “ASC”). These amendments align the requirements in the ASC to the removal of certain disclosure requirements set out in Regulation S-X and Regulation S-K, announced by the SEC. The effective date for each amended topic in the ASC is either the date on which the SEC’s removal of the related disclosure requirement from Regulation S-X or Regulation S-K becomes effective, or on June 30, 2027, if the SEC has not removed the requirements by that date. Early adoption is prohibited. The Company does not expect that the application of this standard will have an impact on its consolidated financial statements and disclosures. In November 2023, the FASB issued ASU 2023-07, Improvements to Reportable Segment Disclosures. This new guidance is designed to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024 on a retrospective basis. Early adoption is permitted. The Company is currently assessing the impact of adopting this new accounting standard on its consolidated financial statements and disclosures. However, the Company does not expect the adoption of ASU 2023-07 to have a material impact on its consolidated financial statements or disclosures. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. ASU 2023-09 requires additional quantitative and qualitative income tax disclosures to enable financial statements users to better assess how an entity’s operations and related tax risks and tax planning and operational opportunities affect its tax rate and prospects for future cash flows. For public business entities, ASU 2023-09 is effective for annual periods beginning after December 15, 2024, which will be the fiscal year ending December 31, 2025 for the Company. The Company expects the adoption to result in enhanced income tax disclosures. Revenue from Loyalty Reward Redemption and Expiration The Company has a customer loyalty program, which allows end-customers to earn and accumulate points with each qualifying purchase. Earned points can be redeemed for loyalty rewards, such as non-cashoutable shopping credit, free shipping, or waived restocking fee, which can be applied to future purchases or returns. Unredeemed points expire after one year from the date the points were earned. Reward coupons expire six months from the date the reward is claimed. Points earned on purchases are a material right, representing a separate performance obligation. The allocated consideration for the points earned through qualifying purchase transactions is deferred based on the standalone selling price of the points, adjusted for expected breakage in proportion to the pattern of redemption, and recorded within deferred revenue under accrued and other current liabilities within the Company’s condensed consolidated balance sheets. Revenue is recognized for these performance obligations at a point in time when rewards are redeemed by the end customer or expired. As of June 30, 2024 and December 31, 2023, the Company had a deferred revenue liability of $1.3 million and $3.1 million, respectively, related to its customer loyalty program, which is included in accrued and other current liabilities within the Company’s condensed consolidated balance sheets. The Company recognized revenue from loyalty reward redemption and expiration of $3.8 million and $2.4 million for the three months ended June 30, 2024 and 2023, respectively, and $7.4 million and $4.6 million for the six months ended June 30, 2024 and 2023, respectively. As our loyalty points expire in 12 months and coupon rewards expire in six months, the revenue for the remaining performance obligation is expected to be recognized within a 12-month period. Gift Cards and Site Credits The Company sells ThredUp gift cards on its e-commerce website and may also convert seller payables and site credits to ThredUp gift cards beginning after one year at the discretion of the Company. ThredUp gift cards do not expire or lose value over periods of inactivity. The Company accounts for gift cards by recognizing a gift card liability at the time a gift card is delivered to the customer. As of June 30, 2024 and December 31, 2023, $7.2 million and $6.6 million, respectively, of gift card liability was included in accrued and other current liabilities within the Company’s condensed consolidated balance sheets. Revenue from redemption of gift cards amounted to $0.3 million and $0.7 million for the three months ended June 30, 2024 and 2023, respectively, and $0.6 million and $1.2 million for the six months ended June 30, 2024 and 2023, respectively. The Company recognizes breakage revenue when it determines that the redemption of gift cards is remote. Breakage revenue was $1.3 million and $2.6 million for the three and six months ended June 30, 2024, respectively. Breakage revenue was not material for the three and six months ended June 30, 2023. The Company issues site credits for returns, which can be applied toward future charges but may not be converted into cash. Site credits may also be converted to ThredUp gift cards beginning after one year at the discretion of the Company. These credits are recognized as revenue when used. As of June 30, 2024 and December 31, 2023, $5.0 million and $4.8 million, respectively, of such customer site credits were included in accrued and other current liabilities within the Company’s condensed consolidated balance sheets. Revenue recognized from the redemption of site credits was $11.4 million and $10.7 million for the three months ended June 30, 2024 and 2023, respectively, and $22.1 million and $20.0 million for the six months ended June 30, 2024 and 2023, respectively. Cash, Cash Equivalents and Restricted Cash The following table provides a reconciliation of cash, cash equivalents and restricted cash reported within the Company’s condensed consolidated balance sheets that sum to the total of the same such amounts shown in the Company’s condensed consolidated statements of cash flows: June 30, December 31, (in thousands) Cash and cash equivalents $ 44,755 $ 56,084 Restricted cash included in Other current assets 335 462 Restricted cash included in Other assets 5,035 4,923 Total cash, cash equivalents, and restricted cash shown in the statement of cash flows $ 50,125 $ 61,469 Fair Value Measurements The Company applies the provisions of FASB ASC Topic 820, Fair Value Measurements and Disclosures , for its financial and non-financial assets and liabilities. ASC 820 defines fair value 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 measurement date. ASC 820 establishes a fair value hierarchy, which prioritizes the inputs used in measuring fair value into three broad levels as follows: • Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. • Level 2 inputs include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability and inputs that are derived principally from or corroborated by observable market data by correlation or other means. • Level 3 inputs are unobservable inputs for the asset or liability. The Company measures certain assets and liabilities at fair value as discussed throughout the notes to its condensed consolidated financial statements. As of June 30, 2024 and December 31, 2023, the carrying amounts of the Company’s accounts receivable, other current assets, other assets, accounts payable, seller payable and accrued and other current liabilities approximated their estimated fair values due to their relatively short maturities. Management believes the terms of its long-term variable-rate debt reflect current market conditions for an instrument with similar terms and maturity, and as such, the carrying value of the Company’s long-term debt approximated its fair value as of June 30, 2024 and December 31, 2023.

As such, the unrealized gains or losses related to the Company’s cash equivalents and marketable securities were not material. For the Company’s marketable securities, which were all classified as available-for-sale, the Company utilizes third-party pricing services to obtain fair value. Third-party pricing methodologies incorporate bond terms and conditions, current performance data, proprietary pricing models, real-time quotes from contributing dealers, trade prices and other market data. The Company determined that the declines in the fair value of its marketable securities were not driven by credit-related factors. During the three and six months ended June 30, 2024 and 2023, the Company did not recognize any losses on its marketable securities due to credit-related factors. As of June 30, 2024, the Company’s money market funds were valued using Level 1 inputs because they were valued using quoted prices in active markets. The Company’s U.S. treasury securities, commercial paper and U.S. government agency bonds were valued using Level 2 inputs because they were valued using quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active. There were no transfers into or out of Level 3 during the three and six months ended June 30, 2024. As of June 30, 2024, all of the $10.5 million carrying amount of marketable securities had a contractual maturity date of less than one year.

Significant Accounting Policies (Policies)	6 Months Ended

Accounting Policies [Abstract]
Basis of Presentation	The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany account balances and transactions have been eliminated upon consolidation. The unaudited condensed consolidated financial statements were prepared in accordance with the United States (“U.S.”) Generally Accepted Accounting Principles (“GAAP”) for interim financial information and with the instructions to Quarterly Report on Form 10‑Q and Article 10 of Regulation S-X. As permitted under those rules, certain footnotes or other financial information may be condensed or omitted.
Use of Estimates	The preparation of consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts that are reported in the consolidated financial statements and the related disclosures. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions include, but are not limited to: the useful lives of property and equipment and intangibles, allowance for sales returns, breakage on loyalty points and rewards and gift cards, valuation of inventory, stock-based compensation, lease liabilities, goodwill and acquired intangible assets.
Recently Adopted Accounting Pronouncements and Accounting Pronouncements Not Yet Effective	There were no accounting pronouncements adopted during the three and six months ended June 30, 2024. Accounting Pronouncements Not Yet Effective In October 2023, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2023-06, “Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative,” to amend certain disclosure and presentation requirements for a variety of topics within the Accounting Standards Codification (the “ASC”). These amendments align the requirements in the ASC to the removal of certain disclosure requirements set out in Regulation S-X and Regulation S-K, announced by the SEC. The effective date for each amended topic in the ASC is either the date on which the SEC’s removal of the related disclosure requirement from Regulation S-X or Regulation S-K becomes effective, or on June 30, 2027, if the SEC has not removed the requirements by that date. Early adoption is prohibited. The Company does not expect that the application of this standard will have an impact on its consolidated financial statements and disclosures. In November 2023, the FASB issued ASU 2023-07, Improvements to Reportable Segment Disclosures. This new guidance is designed to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024 on a retrospective basis. Early adoption is permitted. The Company is currently assessing the impact of adopting this new accounting standard on its consolidated financial statements and disclosures. However, the Company does not expect the adoption of ASU 2023-07 to have a material impact on its consolidated financial statements or disclosures. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. ASU 2023-09 requires additional quantitative and qualitative income tax disclosures to enable financial statements users to better assess how an entity’s operations and related tax risks and tax planning and operational opportunities affect its tax rate and prospects for future cash flows. For public business entities, ASU 2023-09 is effective for annual periods beginning after December 15, 2024, which will be the fiscal year ending December 31, 2025 for the Company. The Company expects the adoption to result in enhanced income tax disclosures.
Revenue from Loyalty Reward Redemption and Expiration, Gift Cards and Site Credits	The Company has a customer loyalty program, which allows end-customers to earn and accumulate points with each qualifying purchase. Earned points can be redeemed for loyalty rewards, such as non-cashoutable shopping credit, free shipping, or waived restocking fee, which can be applied to future purchases or returns. Unredeemed points expire after one year from the date the points were earned. Reward coupons expire six months from the date the reward is claimed. Points earned on purchases are a material right, representing a separate performance obligation. The allocated consideration for the points earned through qualifying purchase transactions is deferred based on the standalone selling price of the points, adjusted for expected breakage in proportion to the pattern of redemption, and recorded within deferred revenue under accrued and other current liabilities within the Company’s condensed consolidated balance sheets. Revenue is recognized for these performance obligations at a point in time when rewards are redeemed by the end customer or expired.
Fair Value Measurements	The Company applies the provisions of FASB ASC Topic 820, Fair Value Measurements and Disclosures , for its financial and non-financial assets and liabilities. ASC 820 defines fair value 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 measurement date. ASC 820 establishes a fair value hierarchy, which prioritizes the inputs used in measuring fair value into three broad levels as follows: • Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. • Level 2 inputs include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability and inputs that are derived principally from or corroborated by observable market data by correlation or other means. • Level 3 inputs are unobservable inputs for the asset or liability. The Company measures certain assets and liabilities at fair value as discussed throughout the notes to its condensed consolidated financial statements. As of June 30, 2024 and December 31, 2023, the carrying amounts of the Company’s accounts receivable, other current assets, other assets, accounts payable, seller payable and accrued and other current liabilities approximated their estimated fair values due to their relatively short maturities. Management believes the terms of its long-term variable-rate debt reflect current market conditions for an instrument with similar terms and maturity, and as such, the carrying value of the Company’s long-term debt approximated its fair value as of June 30, 2024 and December 31, 2023.
