Automatic Check Handling (ACH) - ACH can also mean Automatic Clearinghouse. ACH is a form of epayment or electronic payment. There are two ways payments can be transferred: (1) by wire transfer, or (2) through an automated clearinghouse.

Unlike the wire transfer, it is usually used to process higher volumes or small-dollar payments for settlement issues within 1 to 2 business days. All ACH transactions are settled pretty much the same way checks are. The clearinghouse takes all of the ACH files received daily from member banks, it then divides them by the originating bank (where the check was either cashed or deposited) and the paying bank (the bank where the check was drawn), then it totals the accounts, and credits or deducts the accounts accordingly.
