Supplier invoices arrive as PDF attachments. Someone opens each one, retypes the vendor, date, total and tax into a sheet, renames the file, and moves it to a folder. Twenty invoices a week is roughly two hours of work with a high error rate on the totals.
Never let the model do arithmetic and never let it decide what is valid. It reads; your code checks. Anything that fails validation goes to a review folder with the reason attached, and a human looks at that folder once a day. Ten flagged invoices a week is still ninety percent of the typing gone.
A supplier redesigns their template. A scan comes in rotated. A credit note arrives with negative totals. Build for these early: log every raw model response, keep the original PDF untouched, and make the review folder the default for anything unexpected rather than guessing.
This is a two-to-three day build, not an afternoon, and it needs a week of supervised running before you trust the sheet. After that it is close to invisible — which is the whole point of a good agent.
