Marty Invoice Auditor

Check whether supplied invoice rows match the price you agreed to. If you upload an invoice, ask ChatGPT to read it and show the draft rows first; confirm their accuracy before Marty compares them. You can also paste rows. Marty compares supplied agreed prices, confirmed earlier invoices and same-date prices at other locations. Missing, conflicting or incomplete matches need review. Evidence remains user-supplied and not independently verified; differences are candidates, not confirmed overcharges or credits. Calculate portable credit records from dated events, keeping currencies separate. Issued credit is not realized money. Supplier questions are unsent drafts. Each operation uses only records supplied in that request; keep the complete returned records and supply them again to continue. Evidence references identify user-supplied sources without verifying their contents. The app does not contact suppliers, access supplier portals, save a server workspace or execute financial transactions.
