Microsoft expanded its enterprise AI suite with Copilot for Finance, a new assistant built into Excel and Outlook to automate reconciliations, variance analysis and forecasting tasks. The company said the tool integrates securely with Dynamics 365 and SAP data, reducing manual spreadsheet operations by up to 30 percent. Pilot customers reported faster month-end close cycles and reduced error rates. Analysts view the rollout as deepening Microsoft’s AI defensibility in office software while raising competitive pressure on niche SaaS finance-automation players.
