The way a typical ACH transfer works is as follows: You will initiate the transaction as the originator by sending a Nacha formatted data file containing information about the desired payment to your bank which is called the ODFI (Originating Depository Financial Institution). The ODFI collects these files and sends them to an ACH operator.

ODFI submits ACH file – The originator’s bank or payment processor, also known as the originating depository financial institution (ODFI) submits the ACH entry containing the payment details. This is the first step for both debits and credits. The bank then completes the payment on behalf of the customer.

When this happens, the Receiving Depository Financial Institution (RDFI) automatically initiates a return of the funds to the Originating Depository Financial Institution (ODFI). An ACH return must go through a series of steps to return the funds to the ODFI once it meets the criteria for a return. How do ACH returns work?
