Reverse positive pay flips the standard model: instead of the company sending the bank an issue file, the bank sends the company each day's presented checks, and the company does the matching and tells the bank what to pay. The review burden — and the liability for missed items — sits with the company.
Reverse vs standard positive pay
| Standard positive pay | Reverse positive pay | |
|---|---|---|
| Who matches | Bank | Company |
| Data flow | Issue file to bank | Presented file to company |
| Default on no decision | Typically return | Typically pay — the dangerous difference |
| Best for | Higher check volume, standardized AP | Low volume, or banks that don't offer full positive pay |
| Cost | Higher service fee | Usually cheaper |
The risk to understand
The common default of "pay unless returned" means a missed morning review pays the fraudulent item. If you run reverse positive pay, the daily review needs an owner, a backup, and a calendar block — it is an operational control, not a product you switch on.
