Global Big Four professional services network providing audit, tax, and advisory services across 138 countries.
KPMG delivers three primary professional service lines: Audit and Assurance, Tax and Legal, and Advisory. The Advisory practice covers management consulting, deal advisory, risk consulting, and technology transformation, with industry-aligned offerings for financial services, healthcare, consumer goods, and the public sector.
Branded delivery platforms include the KPMG Clara audit platform, the KPMG Digital Gateway tax workbench, and the KPMG Velocity intelligent automation suite. The Workbench environment, co-developed with Microsoft on Azure AI Foundry, orchestrates AI agents across member firms and underpins the global Microsoft 365 Copilot deployment announced in 2026.
Global demand for professional services tied to AI adoption, regulatory complexity, ESG compliance, cloud transformation, and tax reform continues to expand the addressable market for Big Four networks. KPMG reported aggregated revenues of 39.8 billion dollars for the fiscal year ended 30 September 2025 across 138 countries.
The 2026 expansion of the Microsoft alliance, which includes deploying Microsoft 365 Copilot to all 276,000 professionals and adopting Microsoft Agent 365 for enterprise agent governance, positions KPMG to grow advisory and audit revenue tied to AI implementation while accelerating internal productivity. Competitive pressure from Deloitte, EY, and PwC AI partnerships will shape the trajectory.
As one of the Big Four professional services networks, KPMG sustains scale advantages through a 276,000-person workforce operating across 138 countries and unified Audit, Tax, and Advisory delivery on the KPMG Clara, Digital Gateway, and Workbench platforms. Long-running alliances with Microsoft, Oracle, Salesforce, SAP, ServiceNow, and Workday provide integration with the largest enterprise technology stacks.
The firm Trusted AI framework, country-level AI councils, and 2026 firm-wide rollout of Microsoft 365 Copilot and Microsoft Agent 365 give KPMG a governance-led position in enterprise generative AI. Industry-aligned sector practices and shared global quality standards reinforce the network enterprise brand against Deloitte, EY, and PwC.
