The ACH is a network that electronically moves money from one US bank account to another, allowing businesses and consumers to make electronic payments and money transfers. ACH transactions are available for checking accounts and savings accounts only, processed in batches three times a day. As a result, the typical ACH processing time is three to five business days. Nacha, formerly known as the National Automated Clearing House Association (NACHA), is in charge of the ACH network. While governing the network, Nacha maintains security and ensures that all operations are compliant. The ACH system also connects other financial institutions, such as the Originating Depository Financial Institution (ODFI), which initiates the transaction, and the Receiving Depository Financial Institution (RDFI), which receives the ACH request.
