ACH Credit vs. ACH Debit for Merchant Payments

Start with who initiates the payment

With an ACH credit for a business invoice, the buyer initiates a payment from their bank to the merchant. With an ACH debit, the merchant or its provider initiates a debit against the customer’s account under an authorization. Ask your bank or processor which option it supports for your business and sales channel.

Design a matching step for either workflow

• For buyer-initiated payments, provide a stable invoice reference and explain where the buyer should put it.
• For merchant-initiated payments, associate the authorization and processor transaction ID with the invoice before processing.
• Record the expected amount, account, currency, and payment date. Keep an exception queue for unidentified transfers and partial payments.

Confirm availability before releasing the order

A buyer’s confirmation or a provider status such as submitted may precede a bank posting. Ask what confirms availability for your flow, what can still be returned, and when your agreement allows you to fulfill. Train support to explain the exact status it has verified.
