Claude to audit billing rates against contracts

Chartered accountant Nupur S. Babbar used Claude Cowork during an audit of a growing services company. The workbook connected vendor rosters, platform-recorded hours, invoiced hours, payments, client billing and costs. The goal was to understand mismatches and produce a report the founders could act on.

Cowork worked directly with the files while Babbar ran her own checks in parallel, including roster matching, duplicate detection and hours reconciliation. It flagged a vendor-count mismatch between the roster and payment ledger. It also identified repeated identical hours across months and a client being billed below the contracted rate. A broader difference between recorded work and billing affected the reliability of margin reporting.

The outputs organized findings by severity and separated data gaps, process gaps and control failures. But the draft was not ready for leadership: it repeated background and buried urgent findings. Babbar took over the prioritization, deciding what belonged at the start and what could move to an appendix.

The published names, numbers and identifying details were deliberately changed for confidentiality. Its monetary examples should therefore not be treated as verified loss or recovered revenue. The source says the process and nature of the findings are real. The copyable workflow is independent human reconciliation alongside cross-sheet agent analysis, followed by a human edit that makes the financial decisions clear.
