5 Purchase To Pay AI Agents, Live in Production.

Accounts payable is where a control failure converts directly into cash out of the door. Duplicates are the routine version: the same invoice arrives twice with a different reference, or from a supplier whose name changed after an acquisition, and a check keyed on invoice number finds nothing. Three-way matching is the volume problem — the match itself is mechanical, but every discrepancy sends a clerk back to reopen the purchase order and the receipt to work out what the difference actually is. And invoice redirection fraud exploits the one step in the process that looks administrative: a plausible email asking to update bank details, arriving at a team whose job is to process requests quickly, with no structured check against how that fraud typically presents.

These agents put the checks where the money leaves. Duplicate Invoice Detection finds invoices in a payment run that have already been paid, including the ones with a different number, date, or renamed supplier. Invoice Matching three-way matches against the purchase order and receipt and quantifies every discrepancy, so the exception can be actioned without reopening the documents. Supplier Bank Detail Verification tests a bank change request against the record and against the known presentation of redirection fraud before any payment destination is updated. Supplier Invoice Processing reads an invoice and states which fields the document genuinely supports, rather than which ones a parser guessed — the distinction that decides whether the posting is trustworthy. Where a supplier disagrees, Supplier Invoice Dispute Resolution establishes what each side’s evidence supports, what neither side has established, and what to settle at, and sends nothing.
