Bank transfers & instant payments · On request
ACH debit
ACH debit pulls money from a bank account in the United States over the ACH network, the batch clearing system governed by Nacha and operated by the Federal Reserve and The Clearing House: the payer gives the routing and account numbers and an authorisation, and the provider debits the account. It is not instant, settles in business days and can be returned, but its low flat cost suits recurring and large payments.

How a payment goes through
- The checkout asks for the routing and account numbers, or the payer logs in to their bank through the provider’s verification, and gives the debit authorisation.
- The provider submits the debit to the ACH network in the next batch.
- The debit settles in business days; the provider reports the payment and, later, any return.
- Tranzify writes each status and calls the merchant’s webhook.
ACH debit against cards in the United States
| ACH debit | Cards | |
|---|---|---|
| What the payer needs | a bank account at a US bank | a card accepted by the acquirer |
| Confirmation | business days | at once |
| Cost | low and flat | a percentage of the amount |
| Disputes | returns within the Nacha windows | scheme chargebacks |
| Recurring | yes, by stored authorisation | yes, with tokens |
| Payouts | yes, as ACH credits | push to card, limited |
An ACH debit is a promise rather than a guarantee: the provider reports it paid, and a return for insufficient funds or an unauthorised debit can still arrive within the Nacha windows, so a merchant ships goods or releases funds only after the risk window it accepts.
Who uses it
SaaS and subscription businesses for monthly debits; marketplaces and fintech for large transfers that card limits would stop; education for tuition; e-commerce for high-value orders where a percentage card fee is expensive. A client (a payment company) enables Stripe, Adyen, Checkout.com or Nuvei for ACH debit under its own contract; the integration is enabled on request.
