Your agent handles vendor bills. Most days it reads the invoice and queues the payment. Then a vendor resends the same annual bill in a new email thread, the agent treats it as new, and it pays it again.
Now you are out the cash. The vendor has a credit no one asked for. Your month-end close turns into a long hunt across email, bank logs, and old approvals.
In procurement, this is why people use Three-Way Match.
They do not act on one yes; they match the invoice to the approved order and the receipt, so a resent invoice can die before money moves.
You add one payment gate. The agent can only pay when the invoice, the approved order, and the receipt all line up. No three matches, no payment.
