Positive Pay for Business: Check and ACH Fraud Controls

Positive pay compares presented payment activity against information the business has already authorized. It is designed to catch exceptions before funds leave the account, but only if the company reviews alerts on time.

Editorial note: Bank cutoffs, fees, user limits and treasury-product features vary by institution and account. Confirm live terms before relying on a payment deadline or control setting.

Check positive pay

The business sends issued-check data to the bank. When a check is presented, the bank compares fields such as check number and amount and routes mismatches for review.

Payee positive pay

More advanced services may also compare payee information, adding protection against altered-payee fraud.

ACH controls

ACH debit filters and blocks can restrict which originators may debit the account and may set limits or approval rules.

Exception workflow

The deadline is part of the control

A strong service can fail operationally if no one reviews exceptions before the bank's decision cutoff. Assign ownership and backup coverage.

Match the payment rail to the operating need.

Cost, speed, finality, fraud controls, reconciliation and staff permissions all matter. The best treasury setup is the one that fits the business process—not the one with the most features.
