Four Types of Positive Pay

Check Positive Pay

Verifies each check presented for payment against a list of checks previously authorized and issued by the company. The issuance file includes check number, account number, dollar amount, and payee and is also available for teller line validation of on-us checks presented to be cashed.

Payee Positive Pay

Inspects the check image presented and compares the payee name on the issuance file with the payee on the check image. Any discrepancy flags the check as potentially fraudulent, prompting alerts to be sent to the account holder for further action and supporting teller line validation for on-us checks presented to be cashed.

Reverse Positive Pay

Presents a report of checks that are clearing the account to validate the check number, dollar amount, and payee.

ACH Positive Pay

Allows businesses to view ACH debits and credits posted to their accounts, add vendors to an approved vendor list, and establish limits and frequencies. Transactions not meeting established criteria are flagged so businesses can review and decide legitimacy.

Business ACH

A more convenient, faster, and safer way to make and receive payments.

What is an ACH Payment?

ACH stands for Automated Clearing House, a U.S. financial network for electronic payments and money transfers. ACH payments transfer money from one bank account to another without using check payments, credit card networks, wire transfers, or cash.

For businesses, ACH payments are a popular alternative to physical checks and credit card payments. Because they’re electronic, ACH payments are cost-effective, faster, and more reliable than checks—helping streamline accounting and reconciliation. Generally, it costs less to process an ACH transfer than a credit card payment or wire transfer. If you accept recurring payments, the savings can be significant.

Added protection: By implementing ACH along with Positive Pay, you can have peace of mind knowing your transactions are monitored and protected against potential fraud.

Benefits

  • More convenient
  • Payments show up in your bank register immediately (processing may take a few business days)
  • Makes account reconciliation a lot easier
  • Reduces the risk of check fraud
  • Keeps your bank account information private from vendors
  • A lot less expensive than using paper checks or paying credit card fees

Is ACH for Me?

ACH is for businesses that value convenience, want to save time, and want to prevent fraud. It helps you control whom you pay and when. It can be a great fit if you use payroll services, need to debit customer accounts, or make business-to-business payments. Mid-to-large businesses processing hundreds or thousands of payments each month can see significant savings—while many small businesses prefer ACH for getting paid.
