AI-Powered Accounting Tightens Expense Controls

Generative AI has made receipt manipulation harder to spot, undermining expense checks built around appearance and sampling. Olivier Cornet, UK country manager at SixthFin and a leader at BM&A, says modern accounting controls can continuously cross-check claims against historical spending, corporate-card transactions, merchant records and policy limits. The approach shifts finance teams away from routine document reviews and toward complex cases, while flagging duplicate claims and behavioural anomalies that conventional rules may miss.

The Fintech Times published Cornet’s analysis on July 28, 2026, illustrating the risk with an £80 dinner receipt altered to £180 using AI. A 2024 meta-analysis covering 47 studies found AI fraud detection cut false positives by 40% to 60% compared with rules-based methods, while some industry deployments reported reductions of as much as 80%. McKinsey estimates automation and agentic AI can reduce finance teams’ manual workload by 30% to 50%; Wolters Kluwer expects 44% of finance teams to use AI agents in 2026.
