Research 3: Finance in Microsoft 365 Copilot — bottom-up market size

This report estimates the 2026–2031 EU27 and United Kingdom market for AI assistants and agents in enterprise finance and accounting, with Finance in Microsoft 365 Copilot as the focal product. It is framed for Microsoft product leadership, enterprise-software investors, and strategy teams, and tests whether the market can be built from operating drivers rather than syndicated market-size estimates.

What the report covers

• Bottom-up TAM, SAM, and realistically obtainable market estimates by country, organization size, industry, ERP environment, and finance use case.
• Demand drivers including addressable organizations, finance and accounting employees, shared-service-center populations, Microsoft 365 and ERP penetration, eligible seats, process volumes, adoption curves, seat expansion, attrition, and willingness to pay.
• Use-case segmentation across collections, reconciliation, variance analysis, close support, accounts payable, accounts receivable, forecasting, audit preparation, and management reporting.
• Forecast scenarios for base, upside, downside, and adoption-delay cases from 2026 to 2031, with reproducible assumptions and calculations.
• Competitive comparison of Microsoft’s finance AI proposition against public offerings from SAP, Oracle, Workday, BlackLine, UiPath, ServiceNow, and specialist vendors.
• Decision materials including an executive memo, methodology, findings, sensitivities, recommendation options, risk register, action plan, calculation appendix, unresolved questions, and source ledger.

The analysis uses public evidence available up to 27 July 2026, separates verified facts from assumptions and inferences, and documents data gaps rather than filling them with unsupported estimates.
