Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	1. Organization Liquidity Services, Inc. (Liquidity Services or the Company) is a leading global commerce company providing trusted marketplace platforms that power the circular economy. We create a better future for organizations, individuals, and the planet by capturing and unleashing the intrinsic value of surplus. We connect millions of buyers and thousands of sellers through our leading auction marketplaces, search engines, asset management software, and related services. Our comprehensive solutions enable the transparent, efficient, sustainable recovery of value from excess items owned by business and government sellers. Our business delivers value to shareholders by unleashing the intrinsic value of surplus through our marketplace platforms. These platforms ignite and enable a self-reinforcing cycle of value creation where buyers and sellers attract one another in growing numbers. The result of this cycle is a continuous flow of goods that becomes increasingly valuable as more participants join the platforms, thereby creating positive network effects that benefit sellers, buyers, and shareholders. Results from our operations are organized into four reportable segments: GovDeals, Retail Supply Chain Group (RSCG), Capital Assets Group (CAG) and Machinio. See Note 14 - Segment Information for more information regarding our segments. Liquidity Services was incorporated in Delaware in November 1999 as Liquidation.com, Inc. and commenced operations in early 2000. The Company's operations are subject to certain risks and uncertainties, many of which are associated with technology-oriented companies, including, but not limited to, the Company's dependence on use of the Internet; the effect of general business and economic trends including any future economic impact from the ongoing Russia-Ukraine conflict, increasing tensions between the United States and China, inflationary pressures, recent volatility in the financial services industry, and impacts from interest rate changes; the Company's susceptibility to rapid technological change, actual and potential competition by entities with greater financial and other resources, and the potential for the commercial sellers from which the Company derives a significant portion of its inventory to change the way they conduct their disposition of surplus assets or to otherwise terminate or not renew their contracts with the Company.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies Unaudited Interim Financial Information	2. Summary of Significant Accounting Policies Unaudited Interim Financial Information The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information and the rules and regulations of the Securities and Exchange Commission (SEC). Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, all adjustments, consisting of normal, recurring adjustments considered necessary for a fair presentation, have been included, and intercompany transactions and accounts have been eliminated in conso lidation. The information disclosed in the notes to the condensed consolidated financial statements for these periods is unaudited. Operating results for the three and nine months ended June 30, 2023, are not necessarily indicative of the results that may be expected for the year ending September 30, 2023 , or for any future period. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect amounts in the condensed consolidated financial statements and accompanying notes. For the three and nine months ended June 30, 2023 , these estimates required the Company to make assumptions about the impact of the ongoing Russia-Ukraine conflict, increasing tensions between the United States and China, and other disruptions to macroeconomic conditions and, in turn, the Company's results of operations. The Company will continue to update its assumptions as conditions change. Actual results could differ significantly from those estimates. Contract Assets and Liabilities Contract assets reflect an estimate of expenses that will be reimbursed upon settlement with a seller. The contract asset balance was $ 1.2 million as of June 30, 2023, and $ 0.9 million as of September 30, 2022, and is included in the line item Prepaid expenses and other current assets on the Condensed Consolidated Balance Sheets. Contract liabilities reflect obligations to provide services for which the Company has already received consideration, and generally arise from up-front payments received in connection with Machinio's subscription services. The contract liability balance was $ 4.7 million as of June 30, 2023, and $ 4.4 million as of September 30, 2022, and is included in the line item Deferred revenue on the Condensed Consolidated Balance Sheets. Of the September 30, 2022, contract liability balance, $ 4.2 million was earned as other fee revenue during the nine months ended June 30, 2023. For the Company's Machinio segment, the performance obligation has been identified as the stand ready obligation to provide access to the Machinio subscription services, which it satisfies over time and recognizes as other fee revenues in the line item Consignment and other fee revenues on the Condensed Consolidated Statements of Operations. As of June 30, 2023, the Machinio segment had a remaining performance obligation of $ 4.7 million ; the Company expects to recognize the substantial majority of that amount as other fee revenues over the next 12 months . Contract Costs Contract costs relate to sales commissions paid on subscription contracts that are capitalized within our Machinio segment. Contract costs are amortized over the expected life of the customer contract. The contract cost balance was $ 2.1 million as of June 30, 2023, and $ 1.8 million as of September 30, 2022, and is included in the line item Prepaid expenses and other current assets, and Other assets on the Condensed Consolidated Balance Sheets. Amortization expense was $ 0.3 million and $ 0.9 million during the three and nine months ended June 30, 2023, and $ 0.3 million and $ 0.8 million during the three and nine months ended June 30, 2022 . Treasury Stock Treasury stock is presented at cost, including any applicable excise taxes, commissions and fees, as a reduction of stockholders’ equity in the Condensed Consolidated Balance Sheets and Condensed Consolidated Statement of Stockholders' Equity. Treasury stock held by us may be retired or reissued in the future. Risk Associated with Certain Concentrations For the majority of buyers that receive goods before payment to the Company is made, credit evaluations are performed. However, for the remaining buyers, goods are not shipped before payment is made, and as a result the Company is not subject to significant collection risk from those buyers. For consignment sales transactions, funds are typically collected from buyers and are held by the Company on the sellers' behalf. The funds are included in Cash and cash equivalents on the Condensed Consolidated Balance Sheets. The Company releases the funds to the seller, less the Company's commission and other fees due, through Accounts payable after the buyer has accepted the goods or within 30 days, depending on the state where the buyer and seller conduct business. Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of cash in banks within non-interest bearing, interest-bearing, and earnings allowance checking accounts, as well as cash equivalent money market funds, all of which exceed the applicable U.S. federal (FDIC and/or SIPC) and local jurisdiction (foreign banking institutions) insurance limits, and Accounts receivable. The recent disruptions in the financial services industry have created significant market challenges and uncertainty for entities that bank with those institutions, and which raised significant concern regarding the stability of the banking system in the United States. The Company did not maintain any funds or lending relationships with any of the banks impacted and the banks we do maintain accounts and relationships with have, to date, not experienced any significant disruptions. The Company deposits its cash in interest bearing checking accounts, acquires cash equivalent money market funds, and holds short-term investments designated as held-to-maturity investment securities, each with financial institutions that the Company considers to be of high credit quality. Management continually monitors the financial institutions with whom we conduct business and responds appropriately, when necessary, to manage potential risk exposure to our cash balances above the insurance limits. We have multiple vendor contracts with Amazon.com, Inc. under which we acquire and sell commercial merchandise. While purchase model transactions account for less than 20 % of our total GMV, the cost of inventory for purchase model transactions is the most significant component of our consolidated Costs of goods sold. $ 6.0 million and $ 8.1 million of inventory purchased under such contracts with Amazon.com, Inc. are included in our Consolidated Inventory balances as of June 30, 2023, and September 30, 2022, respectively. Our vendor contracts with respect to sourcing or consigning merchandise for our RSCG segment generally reflect the concentration dynamics inherent to the retail industry. Recent Accounting Pronouncements Accounting Standards Not Yet Adopted In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments (Topic 326) , or Accounting Standards Codification (ASC) 326. ASC 326, including all amendments and related guidance, was designed to provide financial statement users with more useful information about the expected credit losses on financial instruments and other commitments to extend credit. ASC 326 will require estimation of expected credit losses using a methodology that takes into consideration a broad range of reasonable and supportable information. The guidance will be effective for the Company beginning on October 1, 2023, and will be applied on a modified-retrospective basis, with any cumulative-effect adjustment recorded to retained earnings on the adoption date. The Company is in the process of evaluating the impact ASC 326 will have on its condensed consolidated financial statements and expects to estimate credit losses on its financial assets such as its accounts receivable, cash equivalent money market funds, and short-term investments. While the Company has not experienced significant credit losses historically, the materiality of the impact of adoption will depend on events and conditions as of the date of adoption, which cannot be determined conclusively at this time.

Bid4Assets is a leading online marketplace focused on conducting real property auctions for the government, including tax foreclosure sales and sheriff's sales. The results of Bid4Assets' operations are included within our GovDeals reportable segment and reporting unit. The acquisition date fair value of the consideration transferred to the former shareholders of Bid4Assets was approximately $ 42.7 million consisting of $ 14.7 million in cash (net of working capital adjustments totaling $ 0.3 million) and earn-out consideration with a fair value of $ 28.0 million. Former shareholders of Bid4Assets were eligible to receive earn-out consideration of up to $ 37.5 million in cash, payable based on Bid4Assets' achievement of trailing twelve-month EBITDA targets measured at the end of each calendar quarter until the quarter ended December 31, 2022. The Company's allocation of the purchase price to the assets acquired and liabilities assumed as of the Bid4Assets acquisition date of November 1, 2021, is as follows: (in thousands) Fair Value Cash and cash equivalents $ 3,576 Intangible assets 16,500 Other assets 346 Total assets acquired 20,422 Payable to sellers 3,715 Operating lease liabilities 204 Deferred tax liability 3,847 Total liabilities assumed 7,766 Net identifiable assets acquired $ 12,656 Goodwill 30,083 Total consideration transferred $ 42,739 The excess of purchase consideration over the fair value of assets acquired and liabilities assumed was recorded as Goodwill. The Goodwill associated with our acquisition includes the acquired assembled work force, and the value associated with the opportunity to leverage the workforce to continue to grow by adding additional customer relationships or new solutions in the future. Based on management's valuation of the fair value of tangible and intangible assets acquired and liabilities assumed, Goodwill of approximately $ 30.1 million was recorded. The total Goodwill arising from the acquisition is included in the GovDeals reportable segment and reporting unit and is not deductible for tax purposes. The known intangible assets acquired were determined to consist of, and fair valued at, the following: (in thousands) Useful Life (in years) Fair Value Contract intangibles 8 $ 13,900 Developed software 3 2,200 Trade name 3 400 Total identifiable intangible assets  $ 16,500 Contingent Consideration During the year ended September 30, 2022, and as a result of the acquisition of Bid4Assets, the Company recorded contingent consideration in the amount of $ 28.0 million on its Condensed Consolidated Balance Sheets. Through December 31, 2022, $ 3.5 million in earn-out payments were made. The remaining earn-out fair value was $ 0 based upon actual performance through the final earn-out measurement period ending December 31, 2022. See further discussion of this matter within Note 11 - Fair Value Measurement . Other Information Revenue, net income (loss), and pro forma information related to the Bid4Assets acquisition was immaterial to the condensed consolidated financial statements and its related notes for the three and nine months ended June 30, 2022 .

Income Tax Disclosure [Abstract]
Income Taxes	8. Income Taxes The Company’s interim effective income tax rate is based on management’s best current estimate of the Company's expected annual effective income tax rate. The Company recorded pre-tax income in the first nine months of fiscal year 2023 and its corresponding effective tax rate is 26.4 % compared to 11.7 % for the first nine months of fiscal year 2022. The change in the effective tax rate for the nine months ended June 30, 2023 , as compared to the same period in the prior year was primarily due to state and foreign taxes, the utilization of net operating losses, and the inclusion of the $ 20.0 million non-cash gain from the fair-market value adjustment of the Bid4Assets acquisition earn-out liability recorded in the nine months ended June 30, 2022. The effective tax rate differed from the U.S. statutory federal rate of 21 % primarily as a result of the impact of foreign, state, and local income taxes and permanent tax adjustments. The Inflation Reduction Act (IRA) was enacted on August 16, 2022. The IRA includes provisions imposing a 1 % excise tax on share repurchases that occur after December 31, 2022, and introduces a 15 % corporate alternative minimum tax (CAMT) on adjusted financial statement income. The CAMT will be effective for us beginning in fiscal year 2024. We currently are not expecting the IRA to have a material adverse impact on our financial statements. The Company applies the authoritative guidance related to uncertainty in income taxes. ASC 740, Income Taxes , states that a benefit from an uncertain tax position may be recognized when it is more likely than not that the position will be sustained upon examination, including resolution of any related appeals or litigation processes, on the basis of technical merits. During the nine months ended June 30, 2023, the Company recorded a benefit of $ 0.1 million due to the reduction of unrecognized tax benefits related to foreign operations. The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction, various state and local jurisdictions and in foreign jurisdictions, primarily Canada and the United Kingdom. As of June 30, 2023 , the Company has no open income tax examinations in the U.S. and the statute of limitations for years prior to 2019 is now closed. However, certain tax attribute carryforwards that were generated prior to fiscal year 2019 may be adjusted upon examination by tax authorities if they are utilized.

The range of assumptions used to determine the fair value of stock options using the Black-Scholes option-pricing model during the nine months ended June 30, 2023, were as follows: Nine Months Ended June 30, 2023 Dividend yield — Expected volatility 56.87 % - 62.16 % Risk-free interest rate 3.39 % - 3.88 % Expected term 4.5 - 7.6 years SARs During the nine months ended June 30, 2023, the Company did not issue any SARs, while 24,150 SARs were exercised requiring the Company to make cash payments of $0.2 million. As of June 30, 2023, there were no SARs outstanding. Share Repurchase Program From time to time, we may be authorized to repurchase issued and outstanding shares of our common stock under a share repurchase program approved by our Board of Directors. Share repurchases may be made through open market purchases, privately negotiated transactions or otherwise, at times and in such amounts as management deems appropriate. The timing and actual number of shares repurchased will depend on a variety of factors including price, corporate and regulatory requirements and other market conditions. The repurchase program may be discontinued or suspended at any time and will be funded using our available cash. As of September 30, 2022, the Company had $ 6.6 million of remaining share repurchase authorization. On December 6, 2022, and March 13, 2023, the Company's Board of Directors authorized new stock repurchase plans of up to $ 8.4 million and $ 8.0 million, respectively. The Company repurchased 1,607,132 shares for $ 21.2 million during the nine months ended June 30, 2023. As of June 30, 2023 , the Company had $ 1.8 million of remaining authorization to repurchase shares through December 31, 2025. Other Share Repurchases Separate from the share repurchase program, our stock incentive plans allow for participants to exercise stock options by surrendering shares of common stock equivalent in value to the exercise price due. Any shares surrendered to the Company in this manner are not available for future grant. During the nine months ended June 30, 2023 and 2022 , participants surrendered 12,215 and 4,678 shares of common stock, respectively, in the exercise of stock options. Any shares surrendered to the Company in this manner are not available for future grant.

Fair Value Measurement

Fair Value Measurement	9 Months Ended
	Jun. 30, 2023
Fair Value Disclosures [Abstract]
Fair Value Measurement	11. Fair Value Measurement The Company measures and records certain assets and liabilities at fair value on a recurring basis. Authoritative guidance issued by the FASB establishes a fair value hierarchy for those instruments measured at fair value that distinguishes between assumptions based on market data (observable inputs) and the Company’s assumptions (unobservable inputs). The hierarchy consists of three levels: Level 1: Quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity can access at the measurement date; Level 2: Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly; and Level 3: Unobservable inputs for the asset or liability. Cash and cash equivalents . The Company had $ 37.5 million and $ 22.0 million of money market funds considered cash equivalents at June 30, 2023, and September 30, 2022, respectively. These assets were measured at fair value as of June 30, 2023, and September 30, 2022, and were classified as Level 1 assets within the fair value hierarchy. There were no transfers between levels during the periods presented. Contingent consideration . During the year ended September 30, 2022, and as a result of the acquisition of Bid4Assets, Inc. (Bid4Assets), the Company recorded preliminary fair value of contingent consideration in the amount of $ 28.0 million on its Consolidated Balance Sheets as of the acquisition date. The contingent consideration was based on Bid4Assets' achievement of trailing twelve-month EBITDA targets measured at the end of each calendar quarter until the quarter ended December 31, 2022. The liability for this consideration was included in Accrued expenses and other current liabilities within the Consolidated Balance Sheets. The changes in earn-out liability measured at fair value for which the Company has used Level 3 inputs to determine fair value during the three months ended December 31, 2022, was as follows (in thousands): Contingent Balance at September 30, 2022 $ — Change in fair value — Balance at December 31, 2022 $ — Through the earnout period ended December 31, 2022, $ 3.5 million in earn-out payments were made. As of September 30, 2022, the earn-out fair value was estimated to be $ 0 based upon a Monte Carlo simulation of forecasted EBITDA for the final measurement period ending December 31, 2022. As of December 31, 2022, the remaining earn-out fair value was $ 0 based upon actual performance through the final earn-out measurement period ended December 31, 2022. Other Information . When valuing its Level 3 liability, management's estimation of fair value is based on the best information available in the circumstances and may incorporate management's own assumptions around market demand which could involve a level of judgment, taking into consideration a combination of internal and external factors. The Company’s financial assets and liabilities not measured at fair value are cash, short-term investments, accounts receivable, accounts payable, and payables to sellers. The Company believes the carrying values of these instruments approximate fair value. As of June 30, 2023, the Company had no non-financial instruments measured at fair value on a non-recurring basis other than fair value measurements associated with the purchase accounting for Bid4Assets. As of June 30, 2023, and September 30, 2022 , the Company did no t have any material assets or liabilities measured at fair value on a non-recurring basis.

Commitments and Contingencies Disclosure [Abstract]
Legal Proceedings and Other Contingencies	13. Legal Proceedings and Other Contingencies The Company reserves for contingent liabilities based on ASC 450, Contingencies , when it determines that a liability is probable and reasonably estimable. From time to time, the Company may become involved in litigation relating to claims arising in the ordinary course of the business. However, unless otherwise noted, there are no claims or actions pending or threatened against the Company that, if adversely determined, would in the Company's management's judgment have a material adverse effect on the Company. Former Employee Matters In May 2021, the Company’s former Vice President, Human Resources filed a complaint against the Company in federal court in Montgomery County, Maryland, alleging wrongful termination on the basis of gender, race, and age. The parties have completed the discovery phase of this case. On April 4, 2022, the Company filed a motion for summary judgment. The court granted the motion with respect to the age discrimination claim but denied the motion with respect to the race and gender discrimination claims. The Company believes the remaining claims are without merit and cannot estimate a range of potential liability, if any, at this time. The Company’s employment practices liability insurance carrier, CNA, has accepted tender of this claim. The trial for this matter is scheduled to begin on October 30, 2023. In October 2021, the Company’s former Chief Marketing Officer (the “Former CMO”) filed a charge with the Equal Employment Opportunity Commission (the “EEOC”), alleging wrongful termination on the basis of race and age and that the Company retaliated against him. The Company submitted its position statement to the EEOC on February 8, 2022. On December 28, 2022, the Former CMO filed a complaint (the “Original Complaint”), alleging the same claims noted in the EEOC charge in federal court in Montgomery County, Maryland (the “District Court”). The EEOC dismissed the Former CMO’s charge on April 26, 2023. In addition, on April 26, 2023, the Former CMO filed an amended complaint with the District Court, alleging the same claims made in the Original Complaint. The Company believes these claims are without merit and cannot estimate a range of potential liability, if any, at this time. CNA has accepted tender of these claims as well. Unless otherwise noted, based on the information currently available, there are no claims or actions pending or threatened against the Company that, if adversely determined, would have, in Company’s management’s judgment based on the information known to management, a material adverse effect on the Company.

Decisions concerning the allocation of the Company’s resources are made by the Company’s Chief Operating Decision Maker (CODM), which is the Company's Chief Executive Officer, with oversight by the Board of Directors. The Company reports reportable segment information based on the internal performance measures used by the CODM to assess the performance of each operating segment in a given period. In connection with this assessment, the CODM uses direct profit to evaluate the performance of each segment.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies Unaudited Interim Financial Information (Policies)	9 Months Ended
	Jun. 30, 2023
Accounting Policies [Abstract]
Unaudited Interim Financial Information	The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information and the rules and regulations of the Securities and Exchange Commission (SEC). Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, all adjustments, consisting of normal, recurring adjustments considered necessary for a fair presentation, have been included, and intercompany transactions and accounts have been eliminated in conso lidation. The information disclosed in the notes to the condensed consolidated financial statements for these periods is unaudited. Operating results for the three and nine months ended June 30, 2023, are not necessarily indicative of the results that may be expected for the year ending September 30, 2023 , or for any future period.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect amounts in the condensed consolidated financial statements and accompanying notes. For the three and nine months ended June 30, 2023 , these estimates required the Company to make assumptions about the impact of the ongoing Russia-Ukraine conflict, increasing tensions between the United States and China, and other disruptions to macroeconomic conditions and, in turn, the Company's results of operations. The Company will continue to update its assumptions as conditions change. Actual results could differ significantly from those estimates.
Contract Assets and Liabilities; Contract Costs	Contract Assets and Liabilities Contract assets reflect an estimate of expenses that will be reimbursed upon settlement with a seller. The contract asset balance was $ 1.2 million as of June 30, 2023, and $ 0.9 million as of September 30, 2022, and is included in the line item Prepaid expenses and other current assets on the Condensed Consolidated Balance Sheets. Contract liabilities reflect obligations to provide services for which the Company has already received consideration, and generally arise from up-front payments received in connection with Machinio's subscription services. The contract liability balance was $ 4.7 million as of June 30, 2023, and $ 4.4 million as of September 30, 2022, and is included in the line item Deferred revenue on the Condensed Consolidated Balance Sheets. Of the September 30, 2022, contract liability balance, $ 4.2 million was earned as other fee revenue during the nine months ended June 30, 2023. For the Company's Machinio segment, the performance obligation has been identified as the stand ready obligation to provide access to the Machinio subscription services, which it satisfies over time and recognizes as other fee revenues in the line item Consignment and other fee revenues on the Condensed Consolidated Statements of Operations. As of June 30, 2023, the Machinio segment had a remaining performance obligation of $ 4.7 million ; the Company expects to recognize the substantial majority of that amount as other fee revenues over the next 12 months . Contract Costs Contract costs relate to sales commissions paid on subscription contracts that are capitalized within our Machinio segment. Contract costs are amortized over the expected life of the customer contract. The contract cost balance was $ 2.1 million as of June 30, 2023, and $ 1.8 million as of September 30, 2022, and is included in the line item Prepaid expenses and other current assets, and Other assets on the Condensed Consolidated Balance Sheets. Amortization expense was $ 0.3 million and $ 0.9 million during the three and nine months ended June 30, 2023, and $ 0.3 million and $ 0.8 million during the three and nine months ended June 30, 2022 .
Treasury Stock	Treasury Stock Treasury stock is presented at cost, including any applicable excise taxes, commissions and fees, as a reduction of stockholders’ equity in the Condensed Consolidated Balance Sheets and Condensed Consolidated Statement of Stockholders' Equity. Treasury stock held by us may be retired or reissued in the future.
Risk Associated with Certain Concentrations	Risk Associated with Certain Concentrations For the majority of buyers that receive goods before payment to the Company is made, credit evaluations are performed. However, for the remaining buyers, goods are not shipped before payment is made, and as a result the Company is not subject to significant collection risk from those buyers. For consignment sales transactions, funds are typically collected from buyers and are held by the Company on the sellers' behalf. The funds are included in Cash and cash equivalents on the Condensed Consolidated Balance Sheets. The Company releases the funds to the seller, less the Company's commission and other fees due, through Accounts payable after the buyer has accepted the goods or within 30 days, depending on the state where the buyer and seller conduct business. Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of cash in banks within non-interest bearing, interest-bearing, and earnings allowance checking accounts, as well as cash equivalent money market funds, all of which exceed the applicable U.S. federal (FDIC and/or SIPC) and local jurisdiction (foreign banking institutions) insurance limits, and Accounts receivable. The recent disruptions in the financial services industry have created significant market challenges and uncertainty for entities that bank with those institutions, and which raised significant concern regarding the stability of the banking system in the United States. The Company did not maintain any funds or lending relationships with any of the banks impacted and the banks we do maintain accounts and relationships with have, to date, not experienced any significant disruptions. The Company deposits its cash in interest bearing checking accounts, acquires cash equivalent money market funds, and holds short-term investments designated as held-to-maturity investment securities, each with financial institutions that the Company considers to be of high credit quality. Management continually monitors the financial institutions with whom we conduct business and responds appropriately, when necessary, to manage potential risk exposure to our cash balances above the insurance limits. We have multiple vendor contracts with Amazon.com, Inc. under which we acquire and sell commercial merchandise. While purchase model transactions account for less than 20 % of our total GMV, the cost of inventory for purchase model transactions is the most significant component of our consolidated Costs of goods sold. $ 6.0 million and $ 8.1 million of inventory purchased under such contracts with Amazon.com, Inc. are included in our Consolidated Inventory balances as of June 30, 2023, and September 30, 2022, respectively. Our vendor contracts with respect to sourcing or consigning merchandise for our RSCG segment generally reflect the concentration dynamics inherent to the retail industry.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Accounting Standards Not Yet Adopted In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments (Topic 326) , or Accounting Standards Codification (ASC) 326. ASC 326, including all amendments and related guidance, was designed to provide financial statement users with more useful information about the expected credit losses on financial instruments and other commitments to extend credit. ASC 326 will require estimation of expected credit losses using a methodology that takes into consideration a broad range of reasonable and supportable information. The guidance will be effective for the Company beginning on October 1, 2023, and will be applied on a modified-retrospective basis, with any cumulative-effect adjustment recorded to retained earnings on the adoption date. The Company is in the process of evaluating the impact ASC 326 will have on its condensed consolidated financial statements and expects to estimate credit losses on its financial assets such as its accounts receivable, cash equivalent money market funds, and short-term investments. While the Company has not experienced significant credit losses historically, the materiality of the impact of adoption will depend on events and conditions as of the date of adoption, which cannot be determined conclusively at this time.
