ACHACH - Automated clearing house. A method of transferring funds from one bank to another, maintained by the U.S. Federal Reserve. The transfers are processed in batches, and it can take up to 72 hours for a transaction to clear a bank. The ACH is separate from card networks and Galileo processing. is an electronic funds transfer system that enables the bulk transfer of funds between banks, usually within the U.S. An ACH transaction can move funds into the receiver’s account or move funds out of the receiver’s account at the request of the originator and at the authorization of the receiver. ACH transactions are batch-processed and are usually less costly for a bank than paper checks or real-time card transactions. Because processing happens at designated times in batches, an ACH transaction usually takes a few days to settle.
This section is an overview of general ACH use cases, terminology, standards, and the movement of funds in a typical ACH transaction.
You can use ACH to transfer funds electronically between banks. Some common use cases are:
- Direct deposit — An employer obtains account information from an employee and when a paycheck is scheduled, funds move out of the employer’s account and are credited to the employee’s account via ACH.
- Electronic payment — Instead of mailing a paper check, a customer provides account information to a business and, when the customer makes a payment, funds for the payment move out of the customer’s account and into the business’s account via ACH. This is a common payment method for things like gym memberships or mortgage payments.
- Transfer between personal accounts — Your customer has an account at an external bank and wants to transfer funds between the account on your system and the external account. The customer provides you with the external account and routing numbers so that when the customer makes a transfer, funds move out of one account and into the other via ACH.
- Tax refunds and Federal benefits — The U.S. government often pays tax refunds and Federal benefits via ACH. The governmental entity obtains account information from the payee and can make a direct deposit into the account.

- Originator — Entity that initiates the ACH request. The originator can be a bank, business, government institution, or individual account holder.

- Outgoing ACH transaction — ACH transaction that originates inside of Galileo. Sometimes called ACH origination.
- ACH operator — The entity that routes ACH transactions between DFIs and facilitates settlement between them.
- Nacha file — A file containing bulk ACH transaction instructions in a standardized format. The file is transferred between banks by the ACH operator.
