Challenge
Before every month-end close, the business partners and accounting team of a mid-sized group of companies had to check thousands of individual postings for plausibility by hand. The job: identify recurring postings, catch incorrect cost centers, and spot unusual amounts. This took several hours per company and was meant to stop errors before the close.
Solution
We built an AI agent that analyzes individual postings automatically and flags anomalies before the month-end close. It systematically checks for missing recurring entries, validates cost centers against historical patterns, and detects unusual amounts at account level. The system works directly with Power BI exports and delivers focused review notes.

Review time cut from several hours to a few minutes per company
- 2
Early detection of incorrect postings through systematic rather than sample-based checks
- 3
