Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Principles of Consolidation	Note 1—Basis of Presentation and Principles of Consolidation The accompanying financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). These accounting principles were applied on a basis consistent with those of the audited Consolidated Financial Statements contained in our Annual Report on Form 10-K for the year ended December 31, 2021, filed with the Securities and Exchange Commission (the “SEC”) on February 25, 2022 (the “2021 Form 10-K”). The inputs into our judgments and estimates consider the economic implications of COVID-19 on our critical and significant accounting estimates. In the opinion of management, the accompanying unaudited Condensed Consolidated Financial Statements contain all adjustments (consisting of only normal recurring adjustments, except as noted elsewhere in the notes to the Condensed Consolidated Financial Statements) necessary for a fair statement of our financial position as of June 30, 2022, the results of our operations for the three and six months ended June 30, 2022 and 2021, and our cash flows for the six months ended June 30, 2022 and 2021. These statements do not include all of the information and footnotes required by GAAP for annual financial statements. The Condensed Consolidated Financial Statements contained herein should be read in conjunction with the audited Consolidated Financial Statements and footnotes as of and for the year ended December 31, 2021, which were included in the 2021 Form 10-K. The December 31, 2021 Consolidated Balance Sheet data were derived from audited financial statements but do not include all disclosures required by GAAP for annual financial statements. The results of operations for the three and six months ended June 30, 2022 are not necessarily indicative of the expected results for any subsequent quarters or the full year. The accompanying unaudited condensed consolidated financial statements include the accounts of SS&C Technologies Holdings, Inc. and its subsidiaries, including a variable interest entity (“VIE”) for which we are the primary beneficiary. All intercompany balances and transactions have been eliminated in consolidation. Recently Adopted Accounting Pronouncement In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities From Contracts with Customers . ASU 2021-08 requires companies to apply ASC 606 to recognize and measure contract assets and contract liabilities from contracts with customers acquired in a business combination on the acquisition date. Generally, this new guidance will result in an acquirer recognizing contract assets and contract liabilities at the same amounts recorded by the acquiree. Under current GAAP, we have historically recognized contract assets and contract liabilities acquired in a business combination at fair value. ASU 2021-08 is effective for fiscal years beginning after December 15, 2022, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. ASU 2021-08 should be applied prospectively to business combinations that occur after the effective date. We adopted ASU 2021-08 as of January 1, 2022 on a prospective basis. The adoption of this standard did not have a material impact on our financial position, results of operations or cash flows. Recent Accounting Pronouncement Not Yet Effective 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 . ASU 2020-04 provides optional expedients and exceptions for applying GAAP if certain criteria are met to contracts, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued. In January 2021, the FASB issued Update 2021-01, Reference Rate Reform (Topic 848): Scope . The update provides additional optional guidance on the transition from LIBOR to include derivative instruments that use an interest rate for margining, discounting or contract price alignment. The standard will ease, if warranted, the requirements for accounting for the future effects of the rate reform. An entity may elect to apply the amendments prospectively to contract modifications made on or before December 31, 2022. A substantial portion of our indebtedness bears interest at variable interest rates, primarily based on USD-LIBOR. We continue to monitor the impact the discontinuance of LIBOR or another reference rate will have on our contracts, hedging relationships and other transactions. We are currently assessing the impact of this standard on our financial condition and results of operations.

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. As of June 30, 2022 and December 31, 2021, we held certain investment assets and certain liabilities that are required to be measured at fair value on a recurring basis. These investments include money market funds and marketable equity securities where fair value is determined using quoted prices in active markets. Accordingly, the fair value measurements of these investments have been classified as Level 1 in the tables below. Investments for which we elected net asset value as a practical expedient for fair value and investments measured using the fair value measurement alternative are excluded from the tables below. Fair value for deferred compensation liabilities that are credited with deemed gains or losses of the underlying hypothetical investments, primarily equity securities, have been classified as Level 1 in the tables below. The following tables present assets and liabilities measured at fair value on a recurring basis (in millions): Fair Value Measurements at Reporting Date Using June 30, 2022 Quoted prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Money market funds (1) $ 1,242.6 $ 1,242.6 $ — $ — Seed capital investments (2) 34.0 34.0 — — Marketable equity securities (2) 26.8 26.8 — — Deferred compensation liabilities (3) ( 14.2 ) ( 14.2 ) — — Total $ 1,289.2 $ 1,289.2 $ — $ — Fair Value Measurements at Reporting Date Using December 31, 2021 Quoted prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Money market funds (1) $ 1,961.0 $ 1,961.0 $ — $ — Seed capital investments (2) 32.0 32.0 — — Marketable equity securities (2) 40.8 40.8 — — Deferred compensation liabilities (3) ( 21.3 ) ( 21.3 ) — — Total $ 2,012.5 $ 2,012.5 $ — $ — _____________________________________________________ (1) Included in Cash and cash equivalents and Funds receivable and funds held on behalf of clients on the Condensed Consolidated Balance Sheet. (2) Included in Investments on the Condensed Consolidated Balance Sheet . (3) Included in Other long-term liabilities on the Condensed Consolidated Balance Sheet . We have partnership interests in various private equity funds that are not included in the tables above. Our investments in private equity funds were $ 14.8 million and $ 15.5 million at June 30, 2022 and December 31, 2021, respectively, of which $ 12.0 million and $ 12.7 million, respectively, were measured using net asset value as a practical expedient for fair value and $ 2.8 million and $ 2.8 million, respectively, were accounted for under the equity method of accounting. The investments in private equity funds represent underlying investments in domestic and international markets across various industry sectors. Generally, our investments in private equity funds are non-transferable or are subject to long holding periods, and withdrawals from the private equity firm partnerships are typically not permitted. The maximum risk of loss related to our private equity fund investments is limited to the carrying value of its investments in the entities. We add new investment products such as mutual funds and exchange traded funds, through our subsidiary, ALPS Advisors, from time to time by providing the initial cash investments as seed capital. We consolidate seed capital investments when our ownership percentage exceeds 50%. Shares in those investments not owned by us are reflected as a redeemable noncontrolling interest on the condensed consolidated balance sheet.

Business Combinations [Abstract]
Acquisitions	Note 5—Acquisitions Blue Prism On March 16, 2022 , we purchased all of the outstanding stock of Blue Prism Group plc (“Blue Prism”) for approximately $ 1.6 billion in cash, plus the costs of effecting the transaction pursuant to a Scheme of Arrangement entered into under the U.K. Takeover Code. We financed the acquisition by entering into an Incremental Joinder (the “Incremental Joinder”) to the amended and restated credit agreement. Blue Prism is a global leader in enterprise robotics process automation and intelligent automation. The net assets and results of operations of Blue Prism have been included in our Condensed Consolidated Financial Statements from March 16, 2022. The preliminary fair value of the intangible assets, consisting of customer relationships, completed technologies and trade names, was determined using the income approach. Specifically, the relief-from-royalty method was utilized for completed technologies and trade names, and the excess earnings method was utilized for customer relationships. Completed technologies and customer relationships are amortized each year based on the ratio that the projected cash flows for the intangible assets bear to the total of current and expected future cash flows for the intangible assets. Trade names are amortized on a straight-line basis. Customer relationships, completed technologies and trade names are expected to be amortized over approximately fifteen, eight and fourteen years, respectively, in each case the estimated life of the assets. The remainder of the purchase price was allocated to goodwill and a portion is tax deductible. During three months ended June 30, 2022 measurement period adjustments were recorded which resulted in increases in value of approximately $ 28.1 million and $ 4.0 million in customer relationships and completed technologies, respectively, and decreases in value of approximately $ 15.1 million and 3.0 million in deferred tax liabilities and trade names, respectively. Goodwill was also adjusted as a result of the measurement period adjustments. There are $ 62.8 million and $ 73.6 million in revenues from Blue Prism’s operations included in the Condensed Consolidated Statements of Comprehensive Income for the three and six months ended June 30, 2022, respectively. Hubwise On March 25, 2022 , we purchased all of the outstanding stock of Hubwise Holdings Limited (“Hubwise”) for approximately $ 75.0 million in cash, plus the costs of effecting the transaction. Hubwise is a regulated business-to-business investment platform serving advisers, discretionary wealth managers and self-directed direct-to-consumer propositions. The net assets and results of operations of Hubwise have been included in our Condensed Consolidated Financial Statements from March 25, 2022. The preliminary fair value of the intangible assets, consisting of customer relationships, completed technologies and trade names, was determined using the income approach. Specifically, the relief-from-royalty method was utilized for completed technologies and trade names, and the excess earnings method was utilized for customer relationships. Completed technologies and customer relationships are amortized each year based on the ratio that the projected cash flows for the intangible assets bear to the total of current and expected future cash flows for the intangible assets. Trade names are amortized on a straight-line basis. Customer relationships, completed technologies and trade name are expected to be amortized over approximately twelve, eight and fourteen years, respectively, in each case the estimated life of the assets. The remainder of the purchase price was allocated to goodwill and a portion is tax deductible. During three months ended June 30, 2022 , measurement period adjustments were recorded which resulted in decreases in value of approximately $ 14.2 million, $ 2.8 million and $ 4.0 million in completed technologies, customer relationships and deferred income taxes, respectively. Goodwill was also adjusted as a result of the measurement period adjustments. There are $ 1.6 million and $ 1.7 million in revenues from Hubwise’s operations included in the Condensed Consolidated Statements of Comprehensive Income for the three and six months ended June 30, 2022, respectively. T he following summarizes the preliminary allocation of the purchase price for the 2022 acquisitions of Blue Prism and Hubwise (in millions).

Revenues

Revenue from Contract with Customer [Abstract]
Revenues	Note 10—Revenues We generate revenues primarily through our software-enabled services. Our software-enabled services are generally provided under contracts with initial terms of one to five years that require monthly or quarterly payments and are subject to automatic annual renewal at the end of the initial term unless terminated by either party. We also generate revenues by licensing our software to clients through either perpetual or term licenses and by selling maintenance services. We classify license revenues related to sales-based royalty arrangements as term license revenue. Maintenance services are generally provided under annually renewable contracts. Our pricing typically scales as a function of our clients’ assets under management, the complexity of asset classes managed, the volume of transactions and the level of service the client requires. Revenues from professional services consist mostly of services provided on a time and materials basis. Deferred revenues primarily represent unrecognized fees billed or collected for maintenance and professional services. Deferred revenues are recognized as (or when) we perform under the contract. Deferred revenues are recorded on a net basis with contract assets at the contract level. Accordingly, as of June 30, 2022 and December 31, 2021, approximat ely $ 64.8 m illion and $ 61.0 million, respectively, of deferred revenue is presented net within contract assets arising from the same contracts. The amount of revenues recognized in the period that was included in the opening deferred revenues balance was $ 75.2 million and $ 181.3 millio n for the three and six months ended June 30, 2022 , respectively. The amount of revenues recognized in the period that was included in the opening deferred revenue balance was $ 78.7 million and $ 181.8 million for the three and six months ended June 30, 2021, respectively. As of June 30, 2022, revenue of approximately $ 933.4 million is expected to be recognized from remaining performance obligations for license, maintenance and related revenues, of which $ 480.8 million is expected to be recognized over the next twelve months. We record revenue net of any taxes assessed by governmental authorities.

Income Tax Disclosure [Abstract]
Income Taxes	Note 12—Income Taxes The effective tax rate was 29.1 % and 28.8 % for the three months ended June 30, 2022 and 2021, respectively, and 27.9 % and 27.4 % for the six months ended June 30, 2022 and 2021, respectively. The change in the effective tax rate for the three and six months ended June 30, 2022 compared to the respective prior year periods was primarily due a decrease in recognition of windfall tax benefits from stock awards in the current year, an increase in valuation allowances on deferred tax assets in the current year and a proportionate change in the composition of income before income taxes from foreign and domestic tax jurisdictions. In addition, the effective tax rate for the three and six months ended June 30, 2021 included tax expense related to a law change in the United Kingdom. During the six months ended June 30, 2022 , we recorded a net deferred tax liability of $ 118.9 million related primarily to acquired intangible assets in the allocation of the purchase price for the acquisitions of Blue Prism and Hubwise, which will not be deductible for tax purposes and is partially offset by net operating loss carryforwards.

Commitments and Contingencies	Note 14—Commitments and Contingencies From time to time, we are subject to legal proceedings and claims. In our opinion, we are not involved in any litigation or proceedings that would have a material adverse effect on us or our business. Legal Proceedings During the third quarter of 2021, in connection with the ongoing DST ERISA matters and associated legal proceedings described below, including the arbitration awards, we recorded an accrued liability and expense of $ 43.4 million to Other (expense) income, net on the Condensed Consolidated Statement of Comprehensive Income. Due to the inherent uncertainties associated with the resolution of these matters, the ultimate resolution of and any additional potential exposure related to these matters are uncertain at this time. On September 1, 2017, a putative representative action was filed on behalf of the DST 401(k) Profit Sharing Plan (the “Plan”) in the United States District Court for the Southern District of New York, captioned Ferguson, et al v. Ruane Cunniff & Goldfarb Inc., et al. (“Ferguson”), naming as defendants DST, the Compensation Committee of DST’s Board of Directors, the Advisory Committee of the Plan and certain of DST’s present and/or former officers and directors (collectively the “DST Defendants”), alleging breach of fiduciary duties and other violations of the Employee Retirement Income Security Act (“ERISA”). The DST Defendants answered the operative complaint and asserted crossclaims for contribution and/or indemnification against Ruane, Cunniff & Goldfarb Inc.‌(“Ruane”). On January 9, 2020, Ruane filed an amended answer to the amended complaint and asserted crossclaims for contribution and/or indemnification against DST. Both DST and Ruane have filed answers denying the crossclaims asserted against them. On March 8, 2021, the Court entered an order denying without prejudice the plaintiffs’ (the “Ferguson Plaintiffs”) then-pending motions for leave to file a third amended complaint and for class certification, ordering that the parties address the effect, if any, on the Ferguson Plaintiffs’ motions of the March 4, 2021 decision by the United States Court of Appeals for the Second Circuit Court in Cooper v. Ruane Cunniff & Goldfarb Inc. The Ferguson Plaintiffs renewed their motions for leave to file a third amended complaint and for class certification, which motions were fully briefed on May 10, 2021. On August 17, 2021, the Court entered an order certifying a mandatory, non-opt-out class under Federal Rule of Civil Procedure 23(b)(1) that includes all plan participants other than certain plan fiduciaries. Arbitration Claimants, and the Canfield Plaintiffs and Mendon Plaintiffs, each as defined below, filed petitions under Federal Rule of Civil Procedure 23(f) with the Second Circuit on August 30, 2021 and August 31, 2021, respectively, seeking interlocutory review of the Ferguson class certification order, which the Ferguson Plaintiffs and the DST Defendants opposed. The Second Circuit denied the Rule 23(f) petitions on May 24, 2022 and May 25, 2022, respectively. On August 23, 2021, the DST Defendants moved for a temporary restraining order and preliminary injunction against other proceedings, including the below-described arbitrations, which arise out of or relate to the allegations in Ferguson. Following briefing, on November 18, 2021, the Court granted the DST Defendants’ motion and entered a preliminary injunction enjoining the Ferguson class members, including Arbitration Claimants, from instituting new actions or litigating in arbitration or other proceedings against the DST Defendants matters arising out of or relating to the facts or transactions alleged in the Ferguson amended complaint. On November 18, 2021, the Court also ordered the DST Defendants and Arbitration Claimants to submit briefing regarding how the arbitration awards that have been entered against the DST Defendants should be handled in light of the Court’s class certification order and preliminary injunction. On December 15, 2021, Arbitration Claimants and the Canfield Plaintiffs and Mendon Plaintiffs filed appeals of the Court’s preliminary injunction. On December 23, 2021, the DST Defendants, Arbitration Claimants, and the Ferguson Plaintiffs submitted briefs concerning the treatment of the arbitration awards that have been entered against the DST Defendants, and further briefing by the DST Defendants and Arbitration Claimants was submitted on January 26, 2022. On December 31, 2021, Arbitration Claimants moved by order to show cause for an immediate stay of the preliminary injunction pending their appeal to the Second Circuit. On January 3, 2022, the Court denied Arbitration Claimants' motion for an immediate stay and ordered the DST Defendants to show cause as to why the Court should not issue a stay of the preliminary injunction pending appeal. The show-cause order was fully briefed on January 10, 2022. On February 3, 2022, the Court denied Arbitration Claimants’ motion to stay the preliminary injunction pending appeal. In the same order, the Court held that it would determine the status of the arbitration awards already entered against DST at final judgment in the Ferguson action, either after trial or after settlement. On February 4, 2022, Arbitration Claimants filed a motion in the Second Circuit to stay the preliminary injunction pending their appeal of the Court’s preliminary injunction. On June 7, 2022, the Second Circuit denied Arbitration Claimants’ motion to stay the preliminary injunction pending appeal. On February 8, 2022, Arbitration Claimants and the Canfield and Mendon Plaintiffs noticed an appeal of the Court’s February 3, 2022 order. The February 8, 2022 appeal was consolidated with the December 15, 2021 appeal of the preliminary injunction. On May 17, 2022, Arbitration Claimants and the Canfield and Mendon Plaintiffs filed their opening brief in the consolidated appeals. The DST Defendants’ answering brief is due on September 15, 2022. On July 10, 2020, the Ferguson Plaintiffs and the DST Defendants reached an agreement in principle to settle the class claims for $ 27 million, subject to the occurrence of certain conditions, including: Court certification of a “non‑opt-out” class in the case that includes as class members all participants of the Plan, Court approval of the settlement in accordance with applicable law and the satisfactory resolution of claims made by certain other litigants. On September 18, 2020, the parties submitted a letter to the Court disclosing that the Ferguson Plaintiffs and Ruane also had reached a settlement in principle, subject to Court approval. The Ferguson Plaintiffs and the DST Defendants entered into a settlement agreement dated January 8, 2021 memorializing the terms of their proposed settlement, which was filed by the Ferguson Plaintiffs with the Court on the same date. On January 12, 2021, the Ferguson Plaintiffs moved for preliminary approval of the settlement with the DST Defendants, as well as preliminary approval of a separate settlement reached between the Ferguson Plaintiffs and Ruane. Arbitration Claimants and the U.S. Department of Labor (“DOL”) objected to various aspects of those settlements in filings dated January 15, 2021, January 27, 2021, and February 5, 2021. On August 17, 2021, the Court denied the Ferguson Plaintiffs’ motion for preliminary approval of the settlement on the terms proposed. On September 28, 2018, a complaint was filed in the United States District Court for the Southern District of New York captioned Robert Canfield, et al. v. SS&C Technologies Holdings, Inc., et al., on behalf of five individual plaintiffs (the “Canfield Plaintiffs”). On November 5, 2018, a similar complaint was filed in the United States District Court for the Southern District of New York captioned Mark Mendon, et al. v. SS&C Technologies Holdings, Inc., et al., on behalf of two individual plaintiffs (the “Mendon Plaintiffs”). These complaints name as defendants SS&C, the DST Defendants, and Ruane. The underlying claim in each complaint is the same as in the above-described Ferguson matter, with the exception that these actions purport to be brought as individual actions and not putative class actions. On July 10, 2020, the Court entered an order granting the DST Defendants’ motion to disqualify plaintiffs’ counsel in the Canfield and Mendon actions. On March 17, 2021, the Court issued an opinion and order denying the DST Defendants’ motion to disqualify counsel from the arbitrations described below. On April 12, 2021, the Canfield Plaintiffs and Mendon Plaintiffs filed notices of voluntary dismissal dismissing their claims against Ruane with prejudice, which were entered by the Court on April 13, 2021. On April 22, 2021, the DST Defendants filed motions to dismiss the Canfield and Mendon actions. Those motions were fully briefed on May 28, 2021. On November 19, 2021, the Court dismissed the Canfield and Mendon actions. On December 17, 2021, the Canfield Plaintiffs and Mendon Plaintiffs appealed the Court’s November 19, 2021 orders dismissing their respective actions to the Second Circuit. On May 17, 2022, the Canfield Plaintiffs and Mendon Plaintiffs filed their opening briefs in those appeals. The DST Defendants’ answering briefs are due on September 15, 2022. On October 8, 2019, a substantially similar action to the above-described Ferguson, Canfield, Mendon and below-described arbitration matters captioned Scalia v. Ruane, Cunniff & Goldfarb Inc. was filed by the DOL in the United States District Court for the Southern District of New York naming as defendants DST, the Advisory Committee of the Plan, the Compensation Committee of DST’s Board of Directors and certain of DST’s former officers and directors, and alleging that the DST Defendants breached fiduciary duties in violation of ERISA in connection with the Plan. The complaint also names as defendants Ruane and its former Chairman and Chief Executive Officer Robert D. Goldfarb. In the complaint, the DOL seeks disgorgement, damages and any other appropriate injunctive or equitable relief. The DST Defendants moved to dismiss the complaint on December 4, 2020 on the ground that the DOL’s complaint is time-barred. Other defendants also filed motions to dismiss on the same and other grounds. Briefing on the motions to dismiss was completed on February 5, 2021. On March 28, 2022, the court denied Defendants’ motions to dismiss, and Martin J. Walsh was substituted for Eugene Scalia as the plaintiff. On April 11, 2022, the DST Defendants answered the DOL’s complaint. DST, the Advisory Committee of the Plan, and the Compensation Committee of DST’s Board of Directors have been named in 579 substantially similar individual demands for arbitration to date, by former and current DST employees demanding arbitration under the DST Employee Arbitration Program and Agreement (the “Arbitration Claimants”). The underlying claim in each is the same as in the above-described Ferguson matter, with the exception that the arbitrations purport to be brought as individual actions. On November 24, 2021, in light of the preliminary injunction entered in Ferguson discussed above, the American Arbitration Association ceased administration of the arbitrations brought by members of the Ferguson class, which includes all of the Arbitration Claimants with the exception of certain former Plan fiduciaries. As of November 24, 2021, 557 demands for arbitration had been submitted to the American Arbitration Association (the “AAA”). As of the date on which the preliminary injunction was entered, those individual arbitrations were at various stages depending on the particular proceeding. Certain of those arbitrations had resulted in awards against DST and others had resulted in decisions finding no liability as against DST. Many of those decisions were subject to further appeal within the AAA. Certain of the arbitration proceedings had been resolved in whole or in part by settlement. Since November 24, 2021, the AAA has administered only those arbitration proceedings associated with claimants who are not members of the Ferguson class, certain of which have resulted in awards against DST. Between August 20, 2021 and November 17, 2021, counsel for Arbitration Claimants filed 177 motions to confirm certain of the arbitration awards. DST filed responses to those motions. Between October 4 and December 22, 2021, the Western District of Missouri issued orders confirming those 177 arbitration awards and entering judgments against DST. DST has appealed those judgments to the Eighth Circuit. On November 20, 2021, DST requested that the Eighth Circuit stay the pending appeals in light of the preliminary injunction entered in Ferguson. On December 3, 2021, the Eighth Circuit ordered the parties to brief DST’s stay request. On December 17, 2021, Arbitration Claimants and DST filed with the Eighth Circuit their respective briefs addressing the DST’s stay request. On January 3, 2022, the Eighth Circuit declined to stay the briefing schedule on the pending appeals and consolidated those appeals. DST filed its opening brief in the Eighth Circuit on March 24, 2022. Arbitration Claimants filed their opposition brief on April 26, 2022, and DST filed its reply brief on May 18, 2022. The Eighth Circuit heard oral argument on June 14, 2022, and those appeals remain pending. On November 9, 2021, counsel for Arbitration Claimants filed in the Western District of Missouri a petition to compel arbitration captioned Addison v. DST Systems, Inc. (the “Addison Petition”) on behalf of 155 Arbitration Claimants, which DST opposed. On February 14, 2022, the Western District of Missouri stayed the Addison Petition pending resolution of DST’s appeals of the confirmation of the 177 arbitration awards to the Eighth Circuit. We continue to vigorously defend these matters. On November 11, 2020, DST, the Compensation Committee of DST’s Board of Directors, and the Advisory Committee of the Plan as plaintiffs filed a complaint in the United States District Court for the Southern District of New York against Ruane, certain of its related entities, and certain of its current and former employees. The complaint asserts claims for contribution, indemnification, and breach of contract arising out of Ruane’s management of the Plan’s investments and claims for actual and constructive fraudulent conveyances. On May 24, 2021, Defendant Robert Goldfarb filed an answer to the complaint. On September 17, 2021, the remaining defendants filed a pre-motion letter requesting permission to file a motion to dismiss the complaint. On September 22, 2021, the DST plaintiffs responded to the remaining defendants’ pre-motion letter. On November 5, 2021, the Court denied the remaining defendants’ request for a pre-motion conference and granted the remaining defendants leave to file a motion to dismiss. On December 17, 2021, the remaining defendants filed a motion to dismiss the DST plaintiffs’ complaint. On July 27, 2022, the Court denied without prejudice the pending motion to dismiss, and ordered the parties to submit by October 3, 2022 a joint status report with a new briefing schedule on the motion.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Variable Interest Entity Policy	The accompanying unaudited condensed consolidated financial statements include the accounts of SS&C Technologies Holdings, Inc. and its subsidiaries, including a variable interest entity (“VIE”) for which we are the primary beneficiary. All intercompany balances and transactions have been eliminated in consolidation.
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncement In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities From Contracts with Customers . ASU 2021-08 requires companies to apply ASC 606 to recognize and measure contract assets and contract liabilities from contracts with customers acquired in a business combination on the acquisition date. Generally, this new guidance will result in an acquirer recognizing contract assets and contract liabilities at the same amounts recorded by the acquiree. Under current GAAP, we have historically recognized contract assets and contract liabilities acquired in a business combination at fair value. ASU 2021-08 is effective for fiscal years beginning after December 15, 2022, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. ASU 2021-08 should be applied prospectively to business combinations that occur after the effective date. We adopted ASU 2021-08 as of January 1, 2022 on a prospective basis. The adoption of this standard did not have a material impact on our financial position, results of operations or cash flows.
Recent Accounting Pronouncements Not Yet Effective	Recent Accounting Pronouncement Not Yet Effective 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 . ASU 2020-04 provides optional expedients and exceptions for applying GAAP if certain criteria are met to contracts, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued. In January 2021, the FASB issued Update 2021-01, Reference Rate Reform (Topic 848): Scope . The update provides additional optional guidance on the transition from LIBOR to include derivative instruments that use an interest rate for margining, discounting or contract price alignment. The standard will ease, if warranted, the requirements for accounting for the future effects of the rate reform. An entity may elect to apply the amendments prospectively to contract modifications made on or before December 31, 2022. A substantial portion of our indebtedness bears interest at variable interest rates, primarily based on USD-LIBOR. We continue to monitor the impact the discontinuance of LIBOR or another reference rate will have on our contracts, hedging relationships and other transactions. We are currently assessing the impact of this standard on our financial condition and results of operations.
