Steps
Generate and transmit the daily issue file to the bank (serial number, dollar amount, and payee name if payee positive pay is enabled) before the checks are printed or mailed
Let the bank match presented checks against the issue file by serial number and amount (and payee name if activated)
Retrieve same-day and previous-day exception items during the bank's stated exception window (commonly available roughly 9 a.m.–3 p.m. local processing time)
Review each exception — amount mismatch, serial mismatch, stale-dated, duplicate presentment, or payee mismatch — against internal disbursement records
Submit a pay or no-pay decision via API or portal before the bank's decision cutoff (commonly 3 p.m. local processing time)
Log every decision to an internal fraud/exception ledger for audit and confirm the bank's default behavior (pay-all vs return-all) for any exception left undecided
Known gotchas
Missing the decision cutoff triggers the account's default action — confirm whether that default is pay-all or return-all before go-live, since either can be costly
Payee positive pay (name matching) is a separate optional feature with its own OCR/imaging-driven false-positive rate — don't assume it's included with standard serial/amount matching
If the issue file is transmitted after checks are printed or mailed, every legitimate item can be flagged as an exception the first time it's presented
