ACH
ACH (Automated Clearing House) is the U.S. network that moves money between bank accounts in batches rather than one transaction at a time, processed through the Federal Reserve and a private operator and governed by the Nacha operating rules. It powers most direct deposits (ACH credits) and recurring bill payments and subscriptions (ACH debits). ACH transfers are low-cost and typically settle in one to a few business days — slower than a wire, but reversible in ways a wire is not.

What is an ACH authorization form?
An ACH authorization is your written permission letting an organization move money to or from your account electronically through the ACH network. A debit pulls money out; a credit pushes it in. Under Nacha rules, a consumer debit authorization must be written, signed, and clearly state the amount, timing, and how to revoke it.
How to set up direct deposit at a new job
To set up direct deposit at a new job, give payroll a signed direct deposit authorization form with your bank's routing number, account number, and account type, usually backed by a voided check or bank letter. Your first paycheck may still be paper while payroll verifies the account; after that, deposits land automatically each payday.
How to stop an automatic ACH payment you authorized
To stop a recurring ACH payment you authorized, tell the company in writing that you revoke your permission to debit your account, and tell your bank too. Under Regulation E you can also order the bank to stop payment on the preauthorized transfer by notifying it at least three business days before the next debit.
