Positive Pay is a proactive fraud prevention service that helps businesses monitor and control outgoing payments before funds leave their accounts. In practice, it works differently depending on the payment type, though both operate on a strict verification principle.
For Check Positive Pay, you provide a file of issued checks to the bank. Any check presented for payment is automatically compared to this issue file. With ACH Positive Pay, the system uses rules you specify to monitor incoming debits against an approved list of vendors or parameters. If a check or ACH transaction doesn't match your criteria, it is instantly flagged as an exception, giving you the power to block or return it before unauthorized funds disappear.
