ACH is an abbreviation for Automated Clearing House.
ACH Payments are an electronic method for transferring funds between banks and financial institutions. Unlike a paper check, an ACH transaction may be either a debit or credit transaction. Clearing is provided electronically rather than through the physical movement of checks or cash. The ACH Network is an electronic processing and delivery system through which funds are disbursed and settled among a large number of financial institutions. The ACH Network is the nation’s largest electronic payments network.
