Find billing mismatches in contractor invoices
They used an AI to compare a contractor’s paperwork and draft dispute emails that uncovered pricing and change-order problems.
- What they did
- They gave the agent the purchase order, all line items, and every contractor email tied to the project. The agent checked the quoted amounts against what was billed, flagged gaps in the change orders, and wrote detailed dispute emails in the user’s voice.
- How it went
- The user sent those emails with only a little extra work. Over the life of the project, the disputes led to $20K being credited back.
- Tips
- This works best when you feed the agent the full paper trail, not just the latest invoice. Have it pause before any email is sent so you can review the claims and amounts.

Review the purchase order, invoices, change orders, and contractor emails in [folder or file path] for my [project]. Compare the quoted prices with the billed amounts, identify every mismatch or unsupported charge, and show the evidence for each one. Draft a separate dispute email for each issue in my voice. Before sending anything, stop and ask for my approval. End with the total amount I may be able to dispute.
