About ACH

Learn about how ACH works, supported locations, and the different ACH statuses a payment goes through.

What are ACH Payments?

An automated clearing house (ACH) is a computer-based electronic network for processing transactions, usually domestic low value payments, between participating U.S. financial institutions. It may support both credit transfers and direct debits. The ACH system is designed to process batches of payments containing numerous transactions, and it charges fees low enough to encourage its use for low value payments.

Available Countries

ACH processing is only available in United States of America (all 50 states)

How ACH works

ACH payments go through several status updates as it makes its way along the pipeline to be authorized and processed by the networks. The following statuses indicate where an ACH purchase is in the process:

ACH StatusMeaning
PendingThis is the first status that will show immediately after a customer initiates an ACH payment.
BatchedThe ACH System has started processing this transfer.
At this point in time or shortly after, the customer will see the money leave their bank account.
Any potential errors (such as not enough funds) will occur after batching.
SettledThe ACH transaction was successful and funds have been released.
This happens T+3 business days after batching.
(i.e.: Credits were sent to users wallet; USDC was sent to merchant; Delayed Transaction ran).
FailedThe ACH purchase failed after batching for any reason.
This is due to the ACH system rejecting the transfer.

When do ACH payments settle?

ACH payments do not settle for T+3 Business Days after batching. Meaning in the worst case, with a long holiday weekend, someone initiating an ACH payment on Friday afternoon, settlement will not happen until Thursday of the following week. This can cause customer confusion because the purchase is not immediately available in their wallet at the point of purchase.


ACH payments takes 3 business days to settle and authorization is not instant.

To avoid fraud, Coinflow does not finalize credits/USDC/bank transfers until after the ACH payment has fully cleared.

Saved Bank Accounts

Bank accounts are stored for users once entered into the system and can be used for purchasing. Users will be able to conveniently make subsequent purchases, improving the system interaction and improving conversion.

Coinflow is PCI-compliant and does not store the bank account data directly on our servers.
