Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Significant Accounting Policies	1. Organization and Significant Accounting Policies Advantage Solutions Inc. (“Advantage” or the “Company”) is a provider of outsourced solutions to consumer goods companies and retailers. On September 7, 2020, ASI Intermediate Corp., then known as Advantage Solutions Inc. (“ASI”), entered into an agreement and plan of merger (as amended, modified, supplemented or waived, the “Merger Agreement”), with Conyers Park II Acquisition Corp., a Delaware corporation (“Conyers Park”), now known as Advantage Solutions Inc., CP II Merger Sub, Inc., a Delaware corporation and wholly owned subsidiary of Conyers Park (“Merger Sub”), and Karman Topco L.P., then the parent company of ASI (“Topco”). Conyers Park neither engaged in any operations nor generated any revenue. Based on Conyers Park’s business activities, it was a “shell company” as defined under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). On October 28, 2020 (the “Closing Date”), Conyers Park consummated the merger pursuant to the Merger Agreement, and Merger Sub was merged with and into ASI with ASI surviving the merger as a wholly owned subsidiary of Conyers Park (the “Merger” and, together with the other transactions contemplated by the Merger Agreement, the “Transactions”). On the Closing Date, and in connection with the closing of the Transactions (the “Closing”), Conyers Park changed its name to Advantage Solutions Inc. and ASI changed its name to ASI Intermediate Corp. The Company’s Class A common stock is listed on the Nasdaq Global Select Market under the symbol “ADV” and warrants to purchase the Class A common stock at an exercise price of $ 11.50 per share are listed on the Nasdaq Global Select Market under the symbol “ADVWW”. Basis of Presentation The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its subsidiaries. The unaudited condensed consolidated financial statements do not include all of the information required by accounting principles generally accepted in the United States (“U.S. GAAP”). The Condensed Consolidated Balance Sheet at December 31, 2020 was derived from the audited Consolidated Balance Sheet at that date and does not include all the disclosures required by U.S. GAAP. In the opinion of management, all adjustments which are of a normal recurring nature and necessary for a fair statement of the results as of September 30, 2021 and for the three and nine months ended September 30, 2021 and 2020 have been reflected in the condensed consolidated financial statements. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements as of and for the year ended December 31, 2020 and the related footnotes thereto. Operating results for the three and nine months ended September 30, 2021 are not necessarily indicative of the results to be expected during the remainder of the current year or for any future period. COVID-19 Pandemic COVID-19 continues to spread throughout the United States and other countries across the world, and the duration and severity of the effects are currently unknown. The COVID-19 pandemic has impacted the Company and could materially impact the Company’s financial results in the future. The condensed consolidated financial statements presented herein reflect estimates and assumptions made by management at September 30, 2021. Such estimates and assumptions affect, among other things, the Company’s goodwill, long-lived asset and indefinite-lived intangible asset valuation, assessment of the annual effective tax rate and the allowance for expected credit losses. Events and changes in circumstances, including those resulting from the impacts of COVID-19, will be reflected in management’s estimates for future periods. Recent Accounting Standards Recent Accounting Standards Adopted by the Company In December 2019, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2019-12, Simplifying the Accounting for Income Taxes (“ASU 2019-12”), which simplifies the accounting for income taxes, eliminates certain exceptions within ASC 740, Income Taxes, and clarifies certain aspects of the current guidance to promote consistency among reporting entities. ASU 2019-12 is effective for fiscal years beginning after December 15, 2020. The Company adopted ASU 2019-12 on January 1, 2021 and the adoption of this accounting standard did not have a material impact on the Company’s condensed consolidated financial statements. Accounting Standards Recently Issued but Not Yet Adopted by the Company In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. This guidance provides optional expedients and exceptions for U.S. GAAP to contracts, hedging relationships, and other transactions that reference London Interbank Offered Rate (“LIBOR”) or another reference rate if certain criteria are met. The amendments in this update are effective for reporting periods that include or are subsequent to March 12, 2020. Once adopted, the amendments in this update must be applied prospectively to contract modifications and hedging relationships through December 31, 2022. The Company is evaluating the potential impact of this adoption on its consolidated financial statements. In August 2020, the FASB issued ASU No. 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (“ASU 2020-06”), which simplifies accounting for convertible instruments by removing major separation models required under current GAAP. ASU 2020-06 also removes certain settlement conditions that are required for equity-linked contracts to qualify for the derivative scope exception, and it simplifies the diluted earnings per share calculation in certain areas. This update is effective for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. Early adoption is permitted for all entities, including adoption in an interim period. The Company is evaluating the potential impact of this adoption on its consolidated financial statements. In May 2021, the FASB issued ASU 2021-04, Earnings Per Share (Topic 260), Debt—Modifications and Extinguishments (Subtopic 470-50), Compensation—Stock Compensation (Topic 718), and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options (a consensus of the FASB Emerging Issues Task Force). The guidance clarifies certain aspects of the current guidance to promote consistency among reporting of an issuer’s accounting for modifications or exchanges of freestanding equity-classified written call options (for example, warrants) that remain equity classified after modification or exchange. The amendments in this update are effective for all entities for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. Early adoption is permitted for all entities, including adoption in an interim period. The Company is evaluating the potential impact of this adoption on its consolidated financial statements. In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 606): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which requires that an entity recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606 as if it had originated the contracts. Generally, this should result in an acquirer recognizing and measuring the acquired contract assets and contract liabilities consistent with how they were recognized and measured in the acquiree’s financial statements, if the acquiree prepared financial statements in accordance with GAAP. The amendment in this update is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. The guidance should be applied prospectively to business combinations occurring on or after the effective date of the amendment in this update. The Company is evaluating the potential impact of this adoption on its consolidated financial statements. All other new accounting pronouncements issued, but not yet effective or adopted have been deemed to be not relevant to the Company and, accordingly, are not expected to have a material impact once adopted.

Revenue Recognition

Revenue Recognition	9 Months Ended

Revenue from Contract with Customer [Abstract]
Revenue Recognition	2. Revenue Recognition The Company recognizes revenue when control of promised goods or services are transferred to the client in an amount that reflects the consideration that the Company expects to be entitled to in exchange for such goods or services. Substantially all of the Company’s contracts with clients involve the transfer of a service to the client, which represents a performance obligation that is satisfied over time because the client simultaneously receives and consumes the benefits of the services provided. In most cases, the contracts consist of a performance obligation that is comprised of a series of distinct services that are substantially the same and that have the same pattern of transfer (i.e., distinct days of service). For these contracts, the Company allocates the ratable portion of the consideration based on the services provided in each period of service to such period. Revenues related to the sales segment are primarily recognized in the form of commissions, fee-for-service, or on a cost-plus basis for providing headquarter relationship management, analytics, insights and intelligence services, administrative services, retail merchandising services, retailer client relationships and in-store media programs, and digital technology solutions (which include business intelligence solutions, e-commerce services, and content services). Marketing segment revenues are primarily recognized in the form of fee-for-service (including retainer fees, fees charged to clients based on hours incurred, project-based fees, or fees for executing in-person consumer engagements or experiences, which engagements or experiences the Company refers to as “events”), commissions, or on a cost-plus basis for providing experiential marketing, shopper and consumer marketing services, private label development and digital, social, and media services. The Company disaggregates revenues from contracts with clients by reportable segment.

Business Combinations [Abstract]
Acquisitions	3. Acquisitions 2021 Acquisitions During the nine months ended September 30, 2021, the Company acquired six businesses. The acquisitions were accounted for under the acquisition method of accounting. As such, the purchase consideration for each acquired business was allocated to the acquired tangible and intangible assets and liabilities assumed based upon their respective fair values. Assets acquired and liabilities assumed in the business combination were recorded on the Company’s financial statements as of the acquisition date based upon the estimated fair value at such date. The excess of the purchase consideration over the estimated fair value of the net tangible and identifiable intangible assets acquired was recorded as goodwill. The allocation of the excess purchase price was based upon preliminary estimates and assumptions and is subject to revision when the Company receives final information. Accordingly, the measurement period for such purchase price allocations will end when the information, or the facts and circumstances, becomes available, but will not exceed twelve months. The results of operations of each acquired business has been included in the Condensed Consolidated Statements of Operations and Comprehensive Income (Loss) since its respective date of acquisition. The aggregate purchase price for the acquisitions referenced above was $ 73.5 million, which includes $ 40.0 million paid in cash, $ 19.9 million recorded as contingent consideration liabilities, and $ 13.6 million recorded as holdback amounts. Contingent consideration payments are determined based on future financial performance and payment obligations (as defined in the applicable purchase agreement) and are recorded at fair value. The maximum potential payment outcome related to the acquisitions is $ 71.3 million. Holdback amounts are used to withhold a portion of the initial purchase price payment until certain post-closing conditions are satisfied and are typically settled within 24 months of the acquisition. The goodwill related to the acquisitions represented the value paid for the assembled workforce, geographic presence, and expertise. Of the resulting goodwill relating to these acquisitions, $ 14.3 million is deductible for tax purposes. The preliminary fair values of the identifiable assets and liabilities of the acquisitions completed during the nine months ended September 30, 2021, as of the applicable acquisition dates, are as follows: (in thousands) Consideration: Cash $ 40,046 Holdback 13,599 Fair value of contingent consideration 19,883 Total consideration $ 73,528 Recognized amounts of identifiable assets acquired and liabilities assumed: Assets Accounts receivable $ 12,834 Other assets 4,400 Property and equipment 1,001 Identifiable intangible assets 36,210 Total assets 54,445 Liabilities Total liabilities 21,758 Redeemable noncontrolling interest 1,804 Total identifiable net assets 30,883 Goodwill arising from acquisitions $ 42,645 The identifiable intangible assets are amortized on a straight-line basis over their estimated useful lives. The preliminary fair value and estimated useful lives of the intangible assets acquired are as follows: (in thousands) Amount Weighted Average Useful Client relationships $ 27,860 7 years Trade names 5,250 5 years Developed technology 3,100 7 years Total identifiable intangible assets $ 36,210 The operating results of the businesses acquired during the nine months ended September 30, 2021 contributed total revenues of $ 23.0 million and $ 28.2 million in the three and nine months ended September 30, 2021, respectively. The Company has determined that the presentation of net income from the date of acquisition is impracticable due to the integration of the operations upon acquisition. During the three and nine months ended September 30, 2021, the Company incurred $ 0.3 mil lion and $ 0.8 million, respectively, in transaction costs related to the acquisitions described above. These costs have been included in “Selling, general, and administrative expenses” in the Condensed Consolidated Statements of Operations and Comprehensive Income (Loss). 2020 Acquisitions The Company acquired three businesses during the nine months ended September 30, 2020, of which two were sales agencies and one was a marketing agency. The acquisitions were accounted for under the acquisition method of accounting. As such, the purchase consideration for each acquired business was allocated to the acquired tangible and intangible assets and liabilities assumed based upon their respective fair values. Assets acquired and liabilities assumed in the business combination were recorded on the Company’s financial statements as of the acquisition date based upon the estimated fair value at such date. The excess of the purchase consideration over the estimated fair value of the net tangible and identifiable intangible assets acquired was recorded as goodwill. The allocation of the excess purchase price was based upon preliminary estimates and assumptions and is subject to revision when the Company receives final information. Accordingly, the measurement period for such purchase price allocations will end when the information, or the facts and circumstances, becomes available, but will not exceed twelve months. The results of operations of the business acquired by the Company have been included in the Condensed Consolidated Statements of Operations and Comprehensive Income (Loss) since the date of acquisition. The aggregate purchase price for the acquisitions referenced above was $ 72.1 million, which includes $ 51.4 million paid in cash, $ 17.2 million recorded as contingent consideration liabilities, and $ 3.5 million recorded as holdback amounts. Contingent consideration payments are determined based on future financial performance and payment obligations (as defined in the applicable purchase agreement) and recorded at fair value. The maximum potential payment outcome related to the acquisitions is $ 45.8 million. Holdback amounts are used to withhold a portion of the initial purchase price payment until certain post-closing conditions are satisfied and are typically settled within 24 months of the acquisition. The goodwill related to the acquisitions represented the value paid for the assembled workforce, geographic presence, and expertise. Of the resulting goodwill relating to these acquisitions, $ 19.8 million is deductible for tax purposes.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	6. Fair Value of Financial Instruments The Company measures fair value based on the prices 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. Fair value measurements are based on a three-tier hierarchy that prioritizes the inputs used to measure fair value. These tiers include: Level 1, defined as observable inputs, such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs for which little or no market data exists, therefore requiring an entity to develop its own assumptions. The following table sets forth the Company’s financial assets and liabilities measured on a recurring basis at fair value, categorized by input level within the fair value hierarchy. September 30, 2021 (in thousands) Fair Value Level 1 Level 2 Level 3 Assets measured at fair value Cash and cash equivalents $ 168,028 $ 168,028 $ — $ — Derivative financial instruments 5,949 — 5,949 — Total assets measured at fair value $ 173,977 $ 168,028 $ 5,949 $ — Liabilities measured at fair value Derivative financial instruments $ 766 $ — $ 766 $ — Warrant liability 16,210 — — 16,210 Contingent consideration liabilities 65,112 — — 65,112 Total liabilities measured at fair value $ 82,088 $ — $ 766 $ 81,322 December 31, 2020 (in thousands) Fair Value Level 1 Level 2 Level 3 Assets measured at fair value Cash and cash equivalents $ 204,301 $ 204,301 $ — $ — Derivative financial instruments 1,824 — 1,824 — Total assets measured at fair value $ 206,125 $ 204,301 $ 1,824 $ — Liabilities measured at fair value Derivative financial instruments $ 1,882 $ — $ 1,882 $ — Warrant liability 21,234 — — 21,234 Contingent consideration liabilities 45,901 — — 45,901 Total liabilities measured at fair value $ 69,017 $ — $ 1,882 $ 67,135 Interest Rate Cap Agreements The Company had interest rate cap contracts with an aggregate notional value of principal of $ 2.2 billion as of each of September 30, 2021 and December 31, 2020, from various financial institutions to manage the Company’s exposure to interest rate movements on variable rate credit facilities. As of September 30, 2021, the aggregate fair value of the Company’s outstanding interest rate caps represented an outstanding net asset of $ 5.9 million and an outstanding net liability of $ 0.8 million. As of December 31, 2020, the aggregate fair value of the Company’s outstanding interest rate caps represented an outstanding net asset of $ 1.8 million and an outstanding net liability of $ 1.9 million. As of September 30, 2021, $ 5.9 million and $ 0.8 million of fair value of the Company’s outstanding interest rate caps were included in “Prepaid expenses and other current assets” and “Other accrued expenses” in the Condensed Consolidated Balance Sheets, respectively, with changes in fair value recognized as a component of “Interest expense, net” in the Condensed Consolidated Statements of Operations and Comprehensive Income (Loss). As of December 31, 2020, $ 1.8 million, $ 1.0 million, and $ 0.9 million of fair value of the Company’s outstanding interest rate caps were included in “Prepaid expenses and other current assets”, “Other accrued expenses”, and “Other long-term liabilities” in the Condensed Consolidated Balance Sheets, respectively, with changes in fair value recognized as a component of “Interest expense, net” in the Condensed Consolidated Statements of Operations and Comprehensive Income (Loss). During the three months ended September 30, 2021 and 2020, the Company recorded a loss of $ 0.2 million and an immaterial gain of less than $ 0.1 million, respectively, within Interest expense, net, related to changes in the fair value of its derivative instruments. During the nine months ended September 30, 2021 and 2020, the Company recorded a gain within Interest expense, net in the amount of $ 4.1 million, and $ 0.1 million, respectively, related to changes in the fair value of its derivative instruments. Forward Contracts As of September 30, 2021, the Company had three open euro forward contracts to hedge foreign currency exposure on a total of € 1.4 million, with maturities in fiscal year 2021 . As of December 31, 2020, the Company had no open euro forward contracts. During the three months and nine months ended September 30, 2021, the Company recognized $ 0.1 million and $ 0.1 million, respectively, in fair value of the forward contracts. During the three months and nine months ended September 30, 2020, the Company recognized $ 0.4 million and $ 0.5 million, respectively, in fair value of the forward contracts. Warrant Liability The estimated fair value of the liability is recorded using significant unobservable measures and other fair value inputs and is therefore classified as a Level 3 financial instrument. The fair value of the warrants on the date of issuance and on each re-measurement date of certain warrants issued by the Company in a private placement in connection with the Closing (the “private placement warrants”) and classified as liabilities is estimated using the Black-Scholes option pricing model using the following assumptions: September 30, 2021 December 31, 2020 Fair value warrants per share $ 2.21 $ 2.90 Share Price $ 8.65 $ 13.17 Exercise price per share $ 11.50 $ 11.50 Expected term (years) 4.1 4.8 Expected volatility 43.0 % 17.0 % Risk-free interest rate 0.8 % 0.4 % Dividend yield 0.0 % 0.0 % As of September 30, 2021, 7,333,333 private placement warrants remained outstanding at a fair value of $ 16.2 million resulting in $ 3.5 million and $ 5.0 million gain related to the change in fair value of warrant liability for the three and nine months ended September 30, 2021, respectively. The warrant liability is stated at fair value at each reporting period with the change in fair value recorded on the Condensed Consolidated Statements of Operations and Comprehensive Income (Loss) until the warrants are exercised, expire or other facts and circumstances lead the warrant liability to be reclassified as an equity instrument. Contingent Consideration Liabilities Each reporting period, the Company measures the fair value of its contingent liabilities by evaluating the significant unobservable inputs and probability weightings using Monte Carlo simulations. Any resulting decreases or increases in the fair value result in a corresponding gain or loss reported in “Selling, general, and administrative expenses” in the Condensed Consolidated Statements of Operations and Comprehensive Income (Loss). As of September 30, 2021, the maximum potential payment outcomes were $ 291.2 million. The following table summarizes the changes in the carrying value of estimated contingent consideration liabilities: September 30, (in thousands) 2021 2020 Beginning of the period $ 45,901 $ 47,649 Fair value of acquisitions 19,883 17,210 Changes in fair value 6,977 4,162 Payments ( 6,399 ) ( 14,074 ) Note issuance for settlements — ( 6,194 ) Measurement period adjustments ( 1,181 ) — Foreign exchange translation effects ( 69 ) ( 600 ) End of the period $ 65,112 $ 48,153 Long-term Debt The following table sets forth the carrying values and fair values of the Company’s financial liabilities measured on a recurring basis, categorized by input level within the fair value hierarchy: (in thousands) Carrying Value Fair Value Balance at September 30, 2021 Term Loan Credit Facility $ 1,315,063 $ 1,432,132 Notes 775,000 892,991 Notes payable and deferred obligations 2,981 2,981 Total long-term debt $ 2,093,044 $ 2,328,104 (in thousands) Carrying Value Fair Value Balance at December 31, 2020 Term Loan Credit Facility $ 1,325,000 $ 1,447,993 Notes 775,000 884,826 Revolving Credit Facility 50,000 50,000 Notes payable and deferred obligations 3,618 3,618 Total long-term debt $ 2,153,618 $ 2,386,437

Income Tax Disclosure [Abstract]
Income Taxes	8. Income Taxes The Company’s effective income tax rates were 25.4 % and 9.0 % for the three months ended September 30, 2021 and 2020, respectively. The fluctuation in the effective rates during the three months ended September 30, 2021 and 2020 is caused by variations in the Company’s estimated annual effective tax rate from the respective previous quarters and changes in the income (loss) before income taxes in those periods. The Company’s effective tax rate was 36.0 % and 27.6 % during the nine months ended September 30, 2021 and 2020, respectively. The effective tax rate is based upon the estimated income or loss before taxes for the year, by jurisdiction, and adjusted for estimated permanent tax adjustments. The fluctuation in the Company’s effective tax rate was primarily due to a difference in forecasted income (loss) before income taxes used in the annual effective tax rate. Also, the Company recorded discrete items during the nine months ended September 30, 2021, including a valuation allowance of $ 1.3 million for its Mexico operations and income tax expenses of $ 2.3 million and $ 0.8 million to adjust the deferred tax liability resulting from changes in statutory tax rates in certain foreign and state jurisdictions, respectively. These discrete items resulted in a higher tax provision overall for the nine months ended September 30, 2021.

Segment Reporting [Abstract]
Segments	9. Segments The Company’s operations are organized into two reportable segments: sales and marketing. The operating segments reported below are the segments of the Company for which separate financial information is available and for which segment results are evaluated regularly by the chief operating decision maker (i.e., the Company’s Chief Executive Officer) in deciding how to allocate resources and in assessing performance. Through the Company’s sales segment, the Company serves as a strategic intermediary between consumer goods manufacturers and retailer partners and performs critical merchandizing services on behalf of both consumer goods manufacturers and retail partners. Through the Company’s marketing segment, the Company develops and executes marketing programs for manufacturers and retailers. These reportable segments are organized by the types of services provided, similar economic characteristics, and how the Company manages its business. The assets and liabilities of the Company are managed centrally and are reported internally in the same manner as the consolidated financial statements; therefore, no additional information is produced or included herein. The Company and its chief operating decision maker evaluate performance based on revenues and operating income.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	10. Commitments and Contingencies Litigation The Company is involved in various legal matters that arise in the ordinary course of its business. Some of these legal matters purport or may be determined to be class and/or representative actions, or seek substantial damages, or penalties. The Company has accrued amounts in connection with certain legal matters, including with respect to certain of the matters described below. There can be no assurance, however, that these accruals will be sufficient to cover such matters or other legal matters or that such matters or other legal matters will not materially or adversely affect the Company’s business, financial position, or results of operations. Employment Matters The Company has also been involved in various litigation, including purported class or representative actions with respect to matters arising under the California Labor Code and Private Attorneys General Act. The Company has retained outside counsel to represent it in these matters and is vigorously defending its interests. Legal Matters Related to Take 5 On April 1, 2018, the Company acquired certain assets and assumed liabilities of Take 5 Media Group (“Take 5”). In June 2019, as a result of a review of internal allegations related to inconsistency of data provided by Take 5 to its clients, the Company commenced an investigation into Take 5’s operations. In July 2019, as a result of the Company’s investigation, the Company determined that revenue during the fiscal year ended December 31, 2018 attributable to the Take 5 business had been recognized for services that were not performed on behalf of clients of Take 5 and that inaccurate reports were made to Take 5 clients about those services (referred to as the “Take 5 Matter”). As a result of these findings, in July 2019, the Company terminated all operations of Take 5, including the use of its associated trade names and the offering of its services to its clients and offered refunds to Take 5 clients of collected revenues attributable to Take 5 since the Company’s acquisition of Take 5. USAO and FBI Voluntary Disclosure and Investigation Related to Take 5 The Company voluntarily disclosed to the United States Attorney’s Office and the Federal Bureau of Investigation certain misconduct occurring at Take 5, a line of business that the Company closed in July 2019. The Company intends to cooperate in this and any other governmental investigations that may arise in connection with the Take 5 Matter. At this time, the Company cannot predict the ultimate outcome of any investigation related to the Take 5 Matter and is unable to estimate the potential impact such an investigation may have on the Company. Arbitration Proceedings Related to Take 5 In August 2019, as a result of the Take 5 Matter, the Company provided a written indemnification claim notice to the sellers of Take 5 (the “Take 5 Sellers”) seeking monetary damages (including interest, fees and costs) based on allegations of breach of the asset purchase agreement (the “Take 5 APA”), as well as fraud. In September 2019, the Take 5 Sellers initiated arbitration proceedings against the Company, alleging breach of the Take 5 APA as a result of the Company’s decision to terminate the operations of the Take 5 business, and seeking monetary damages equal to all unpaid earn-out payments under the Take 5 APA (plus interest, fees and costs). In 2020, the Take 5 sellers amended their statement of claim to allege defamation, relating to statements the Company made to customers in connection with terminating the operations of the Take 5 business, and seeking monetary damages for the alleged injury to their reputation. The Company filed its response to the Take 5 Sellers’ claims, and asserted indemnification, fraud and other claims against the Take 5 Sellers as counterclaims and cross-claims in the arbitration proceedings. The Company is currently unable to estimate the potential impact related to these arbitration proceedings, but the Company has retained outside counsel to represent the Company in these matters and intends to vigorously pursue the Company’s interests. Other Legal Matters Related to Take 5 The Take 5 Matter may result in additional litigation against the Company, including lawsuits from clients, or governmental investigations, which may expose the Company to potential liability in excess of the amounts being offered by the Company as refunds to Take 5 clients. The Company is currently unable to determine the amount of any potential liability, costs or expenses (above the amounts already being offered as refunds) that may result from any lawsuits or investigations associated with the Take 5 Matter or determine whether any such issues will have any future material adverse effect on the Company’s financial position, liquidity, or results of operations. Although the Company has insurance covering certain liabilities, the insurance may not be sufficient to cover any potential liability or expenses associated with the Take 5 Matter.

Noncontrolling Interest [Abstract]
Redeemable Noncontrolling Interest	11. Redeemable Noncontrolling Interest The Company is party to a put and call option agreement with respect to the common securities that represent the remaining noncontrolling interest from a majority-owned subsidiary, which was established through a majority-owned international joint venture during the nine months ended September 30, 2021. The put and call option agreement representing 20 % of the total outstanding noncontrolling equity interest of that subsidiary, may be exercised at the discretion of the noncontrolling interest holder by providing written notice to the Company beginning in 2026 and expiring in 2028 . The redemption value of the put and call option agreement is based on a multiple of the majority-owned subsidiary earnings before interest, taxes, depreciation and amortization subject to certain adjustments. The noncontrolling interest is subject to a put option that is outside of the Company’s control, and is presented as redeemable non-controlling interest in the temporary equity section of the Condensed Consolidated Balance Sheets. The Company recorded its redeemable noncontrolling interest at fair value on the date of the related business combination transaction and recognizes changes in the redemption value at the end of each reporting period. The carrying value of the redeemable noncontrolling interest was $ 1.8 million as of September 30, 2021.

Share-based Payment Arrangement [Abstract]
Stock-Based Compensation	12. Stock-Based Compensation The Company has issued nonqualified stock options, restricted stock units, and performance restricted stock units under the Advantage Solutions Inc. 2020 Incentive Award Plan (the “ Plan ”). As of September 30, 2021, the number of nonqualified stock options outstanding was immaterial. The Company’s restricted stock units and performance restricted stock units, as described below, are expensed and reported as non-vested shares. The Company recognized stock-based compensation expense of $ 8.3 million and $ 28.5 million in the three and nine months ended September 30, 2021, respectively. The related deferred tax benefit for stock-based compensation recognized was $ 1.3 million and $ 4.4 million for the three and nine months ended September 30, 2021, respectively. Performance Restricted Stock Units Performance restricted stock units (“PSUs”) are subject to the achievement of certain performance conditions based on the Company’s revenues and Adjusted EBITDA targets in the respective measurement period and the recipient’s continued service to the Company. The PSUs are scheduled to vest over a three-year period from the date of grant and may vest from 0 % to 150 % of the number of shares set forth in the table below. The number of PSUs earned shall be adjusted to be proportional to the partial performance between the Threshold Goals, Target Goals and Maximum Goals. Details for each aforementioned defined term for each grant have been provided in the table below.

The maximum potential expense if the Maximum Goals were met for these awards has been provided in the table above. Recognition of expense associated with performance-based stock is not permitted until achievement of the performance targets are probable of occurring. Restricted Stock Units Restricted stock units (“RSUs”) are subject to the recipient’s continued service to the Company. The RSUs are generally scheduled to vest over three years and are subject to the provisions of the agreement under the Plan. During the nine months ended September 30, 2021, the following activities involving RSUs occurred under the Plan: Number of RSUs Weighted Average Grant Outstanding at January 1, 2021 — $ — Granted 3,858,699 10.84 Vested 41,424 13.22 Forfeited 187,075 12.98 Outstanding at September 30, 2021 $ 3,630,200 $ 13.17 As of September 30, 2021, the total remaining unrecognized compensation cost related to RSUs amounted to $ 28.2 million, which will be amortized over the weighted-average remaining requisite service periods of 2.4 years.

Earnings Per Share

Earnings Per Share	9 Months Ended
	Sep. 30, 2021
Earnings Per Share [Abstract]
Earnings Per Share	13. Earnings Per Share The Company calculates earnings per share using a dual presentation of basic and diluted earnings per share. Basic earnings per share is calculated by dividing net income (loss) attributable to stockholders of the Company by the weighted-average shares of common stock outstanding without the consideration for potential dilutive shares of common stock. Diluted earnings per share represents basic earnings per share adjusted to include the potentially dilutive effect of outstanding share option awards, non-vested share awards, common stock warrants, and Performance Shares (as defined below). Diluted earnings per share is computed by dividing the net income by the weighted-average number of common share equivalents outstanding for the period determined using the treasury stock method and if-converted method, as applicable. During periods of net loss, diluted loss per share is equal to basic loss per share because the antidilutive effect of potential common shares is disregarded. As a result of the Transactions, the Company has retrospectively adjusted the weighted-average number of common shares outstanding prior to October 28, 2020 by multiplying them by the exchange ratio used to determine the number of common shares into which they converted. The following is a reconciliation of basic and diluted net earnings (loss) per common share: Three Months Ended September 30, Nine Months Ended September 30, (in thousands, except share and earnings per share data) 2021 2020 2021 2020 Basic earnings per share computation: Numerator: Net income (loss) attributable to stockholders of Advantage Solutions Inc. $ 23,311 $ 35,949 $ 29,316 $ ( 23,163 ) Denominator: Weighted average common shares - basic 318,563,497 203,750,000 318,213,337 203,750,000 Basic earnings (loss) per common share $ 0.07 $ 0.18 $ 0.09 $ ( 0.11 ) Diluted earnings per share computation: Numerator: Net income (loss) attributable to stockholders of Advantage Solutions Inc. $ 23,311 $ 35,949 $ 29,316 $ ( 23,163 ) Denominator: Weighted average common shares outstanding 318,563,497 203,750,000 318,213,337 203,750,000 Restricted Stock Units 1,450,668 — 1,335,011 — Employee stock purchase plan and stock options 106,469 — 106,469 — Weighted average common shares - diluted 320,120,634 203,750,000 319,654,817 203,750,000 Diluted earnings (loss) per common share $ 0.07 $ 0.18 $ 0.09 $ ( 0.11 ) During periods of net loss, diluted loss per share is equal to basic loss per share because the antidilutive effect of potential common shares is disregarded. As part of the Transactions, 5,000,000 shares of Class A common stock were issued to Topco at Closing (the “Performance Shares”), which were subject to vesting upon satisfaction of a market performance condition for any period of 20 trading days out of 30 consecutive trading days during the five-year period after the Closing. Topco was not able to vote or sell such shares until vesting. The Performance Shares vested on January 15, 2021, when the closing price for the Class A common stock exceeded $ 12.00 per share for 20 trading days out of 30 consecutive trading days and were included in the September 30, 2021 earnings per share calculation. The Company had 18,578,324 warrants, including 7,333,333 private placement warrants held by CP Sponsor, to purchase Class A common stock at $ 11.50 per share outstanding at the Closing, and 5,001 warrants were exercised during the nine months ended September 30, 2021. The computation of diluted net income per share does no t include the assumed exercise of warrants since that would have an antidilutive effect on earnings per share for the three and nine months ended September 30, 2021.

Subsequent Events	14. Subsequent Events Repricing of Long-Term Debt On October 28, 2021 (the “First Lien Amendment Effective Date”), Advantage Sales & Marketing Inc. (the “Borrower”), an indirect wholly-owned subsidiary of the Company, together with Karman Intermediate Corp., a Delaware corporation (“Holdings”) and certain of the Borrower’s subsidiaries, entered into Amendment No. 1 to the First Lien Credit Agreement (the “First Lien Amendment”), which amended the First Lien Credit Agreement, dated October 28, 2020, by and among the Borrower, Holdings, Bank of America, N.A., as administrative agent and collateral agent (“Bank of America”), each lender party from time to time thereto, and the other parties thereto. The First Lien Amendment was entered into by the Borrower to reduce the applicable interest rate on the term loan to 5.25 % per annum. Additional terms and provisions amended include (i) resetting the period for six months following the First Lien Amendment Effective Date in which a 1.00 % prepayment premium shall apply to any prepayment of the term loan in connection with certain repricing events, and (ii) updating the provisions by which U.S. Dollar LIBOR will eventually be replaced with SOFR or another interest rate benchmark to reflect the most recent standards and practices used in the industry and by Bank of America. On October 28, 2021, the Borrower and Holdings also entered into the First Amendment to ABL Revolving Credit Agreement (the “ABL Amendment”), which amended the ABL Revolving Credit Agreement, dated October 28, 2020, by and among the Borrower, Holdings, the lenders from time to time party thereto and Bank of America, as administrative agent. The ABL Amendment was entered into by the Borrower to amend certain terms and provisions, including (i) reducing the interest rate floor for Eurocurrency rate loans from 0.50 % to 0.00 % and base rate loans from 1.50 % to 1.00 %, and (ii) updating the provisions by which U.S. Dollar LIBOR will eventually be replaced with SOFR or another interest rate benchmark to reflect the most recent standards and practices used in the industry and by Bank of America. Share Repurchase Program On November 9, 2021, the Company announced that the Board of Directors authorized a new share repurchase program (the “2021 Share Repurchase Program”) pursuant to which the Company may repurchase up to $ 100 million of the Company’s Class A common stock. The 2021 Share Repurchase Program does not have an expiration date, but provides for suspension or discontinuation at any time. The 2021 Share Repurchase Program permits the repurchase of our Class A common stock on the open market from time to time. The timing and amount of any share repurchase is subject to prevailing market conditions, relevant securities laws and other considerations, and the Company is under no obligation to repurchase any specific number of shares.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its subsidiaries. The unaudited condensed consolidated financial statements do not include all of the information required by accounting principles generally accepted in the United States (“U.S. GAAP”). The Condensed Consolidated Balance Sheet at December 31, 2020 was derived from the audited Consolidated Balance Sheet at that date and does not include all the disclosures required by U.S. GAAP. In the opinion of management, all adjustments which are of a normal recurring nature and necessary for a fair statement of the results as of September 30, 2021 and for the three and nine months ended September 30, 2021 and 2020 have been reflected in the condensed consolidated financial statements. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements as of and for the year ended December 31, 2020 and the related footnotes thereto. Operating results for the three and nine months ended September 30, 2021 are not necessarily indicative of the results to be expected during the remainder of the current year or for any future period.
COVID-19 Pandemic	COVID-19 Pandemic COVID-19 continues to spread throughout the United States and other countries across the world, and the duration and severity of the effects are currently unknown. The COVID-19 pandemic has impacted the Company and could materially impact the Company’s financial results in the future. The condensed consolidated financial statements presented herein reflect estimates and assumptions made by management at September 30, 2021. Such estimates and assumptions affect, among other things, the Company’s goodwill, long-lived asset and indefinite-lived intangible asset valuation, assessment of the annual effective tax rate and the allowance for expected credit losses. Events and changes in circumstances, including those resulting from the impacts of COVID-19, will be reflected in management’s estimates for future periods.
Recent Accounting Standards	Recent Accounting Standards Recent Accounting Standards Adopted by the Company In December 2019, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2019-12, Simplifying the Accounting for Income Taxes (“ASU 2019-12”), which simplifies the accounting for income taxes, eliminates certain exceptions within ASC 740, Income Taxes, and clarifies certain aspects of the current guidance to promote consistency among reporting entities. ASU 2019-12 is effective for fiscal years beginning after December 15, 2020. The Company adopted ASU 2019-12 on January 1, 2021 and the adoption of this accounting standard did not have a material impact on the Company’s condensed consolidated financial statements. Accounting Standards Recently Issued but Not Yet Adopted by the Company In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. This guidance provides optional expedients and exceptions for U.S. GAAP to contracts, hedging relationships, and other transactions that reference London Interbank Offered Rate (“LIBOR”) or another reference rate if certain criteria are met. The amendments in this update are effective for reporting periods that include or are subsequent to March 12, 2020. Once adopted, the amendments in this update must be applied prospectively to contract modifications and hedging relationships through December 31, 2022. The Company is evaluating the potential impact of this adoption on its consolidated financial statements. In August 2020, the FASB issued ASU No. 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (“ASU 2020-06”), which simplifies accounting for convertible instruments by removing major separation models required under current GAAP. ASU 2020-06 also removes certain settlement conditions that are required for equity-linked contracts to qualify for the derivative scope exception, and it simplifies the diluted earnings per share calculation in certain areas. This update is effective for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. Early adoption is permitted for all entities, including adoption in an interim period. The Company is evaluating the potential impact of this adoption on its consolidated financial statements. In May 2021, the FASB issued ASU 2021-04, Earnings Per Share (Topic 260), Debt—Modifications and Extinguishments (Subtopic 470-50), Compensation—Stock Compensation (Topic 718), and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options (a consensus of the FASB Emerging Issues Task Force). The guidance clarifies certain aspects of the current guidance to promote consistency among reporting of an issuer’s accounting for modifications or exchanges of freestanding equity-classified written call options (for example, warrants) that remain equity classified after modification or exchange. The amendments in this update are effective for all entities for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. Early adoption is permitted for all entities, including adoption in an interim period. The Company is evaluating the potential impact of this adoption on its consolidated financial statements. In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 606): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which requires that an entity recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606 as if it had originated the contracts. Generally, this should result in an acquirer recognizing and measuring the acquired contract assets and contract liabilities consistent with how they were recognized and measured in the acquiree’s financial statements, if the acquiree prepared financial statements in accordance with GAAP. The amendment in this update is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. The guidance should be applied prospectively to business combinations occurring on or after the effective date of the amendment in this update. The Company is evaluating the potential impact of this adoption on its consolidated financial statements. All other new accounting pronouncements issued, but not yet effective or adopted have been deemed to be not relevant to the Company and, accordingly, are not expected to have a material impact once adopted.
