Silver Lake is bringing together two major French business software groups, Cegid and Silae, in a transaction that would create a European technology company valued at more than €10 billion.
The combination is particularly significant for the tax, accounting and finance technology market. The new group would bring together software covering accounting, tax, e-invoicing, payroll, HR, digital financial services and payments at a time when AI and regulatory digitalisation are rapidly reshaping enterprise software.
A €10 Billion European Software Group
Cegid and Silae announced on 9 September 2026 their intention to merge, with the transaction expected to close during the first half of 2027.
Silver Lake, the US technology-focused private equity firm and majority owner of both businesses, will retain a controlling interest in the combined company.
According to the Financial Times, the new group is expected to generate approximately €1.6 billion in annual revenue and would be valued at more than €10 billion.
Christian Pedersen has been appointed CEO of Cegid and is expected to lead the combined group. Silver Lake managing partner Christian Lucas is expected to serve as chair.
Combining Accounting, Tax, Payroll and E-Invoicing
The strategic importance of the transaction extends well beyond its valuation.
Cegid provides cloud business management software across areas including finance, accounting, tax, HR and retail. Silae is a major French payroll and HR technology platform.
Together, including Cegid’s recently acquired Shine business, the companies say their platforms support the accounting, tax, finance and payroll activities of around 2 million end customers and more than 15,000 chartered accountancy firms across Europe.
They also process more than 13 million payslips every month.
The proposed combination is intended to create a more integrated platform covering:
• E-invoicing
• Accounting
• Tax
• Payroll
• Human resources
• Digital financial services
• Payments
For tax and finance functions, this reflects a broader movement towards integrated technology ecosystems in which tax compliance increasingly sits within wider financial and transactional data flows.
AI Is Part of the Deal Rationale
Artificial intelligence is also central to the strategic rationale.
According to the Financial Times, combining Cegid and Silae would allow the businesses to integrate their software and data more closely while supporting greater investment in AI-based solutions.
The transaction comes as AI creates both opportunities and challenges for traditional enterprise software providers.
Rather than operating multiple standalone applications, software groups are increasingly seeking to combine data, workflows and AI capabilities across accounting, finance, tax, payroll and other business processes.
For tax technology, the implications could be significant. AI capabilities become considerably more powerful when they can operate across integrated financial and compliance datasets rather than isolated tax applications.
E-Invoicing Adds Another Strategic Dimension
The transaction also comes during a major transformation of European invoicing and tax compliance.
Mandatory B2B e-invoicing and digital reporting requirements are expanding across Europe, creating increasing demand for technology capable of connecting invoicing, accounting, tax determination, reporting and financial data.
Cegid already operates across multiple European markets, while the proposed combination would give the new group substantial access to businesses and accounting firms.
An integrated platform connecting e-invoicing with accounting, tax and payment processes could therefore become strategically important as tax authorities continue moving towards increasingly digital and transaction-level reporting environments.
Private Equity Consolidation Meets Tax Technology
Silver Lake has backed Cegid since 2016 and Silae since 2020.
The transaction therefore represents the combination of two existing portfolio investments rather than a conventional acquisition of an unrelated target.
According to the Financial Times, Silver Lake is expected to retain approximately 66% to 75% of the combined company.
The transaction would not immediately return capital to Silver Lake or the minority investors. Instead, the strategy appears focused on building a larger European software platform with greater scale, operational integration and capacity to invest in AI.
A larger combined business could also potentially provide a path towards a future European stock-market listing.
Debt and Efficiency Will Also Matter
The combination takes place against a backdrop of relatively high leverage at Cegid.
Cegid has completed several debt-financed acquisitions, including its recent acquisition of fintech company Shine.
S&P Global downgraded Cegid’s credit rating in 2026, pointing to elevated credit ratios following rapid debt-financed acquisitions.
The Financial Times reported that greater efficiency from combining Cegid and Silae could help address the debt burden alongside the strategic benefits of greater scale.
This means execution will matter. Integrating large enterprise software businesses while simultaneously investing in AI, managing leverage and maintaining product development can be operationally complex.
A European Tax and Accounting Technology Champion?
Perhaps the most interesting aspect of the transaction is its ambition.
Europe has produced several substantial accounting, payroll and tax technology businesses, but relatively few have achieved the scale of the largest US enterprise software groups.
Combining Cegid and Silae would create a business spanning accounting, tax, e-invoicing, payroll, HR, payments and financial services with a valuation exceeding €10 billion.
As tax compliance becomes increasingly embedded within enterprise technology, the boundaries between accounting software, tax technology, payments and regulatory reporting are also becoming less distinct.
The Cegid-Silae transaction is therefore more than another software M&A deal.
It illustrates how AI, e-invoicing, tax digitalisation and software consolidation are increasingly converging — and why scale is becoming a strategic advantage in the European tax and accounting technology market.
