What is the Automated Clearing House?

ACH is an electronic network for financial transactions in the United States.  The Automated Clearing House processes large volumes of credit and debit transactions in batches.  ACH credit transfers include direct deposit payroll and vendor payments.  ACH direct debit transfers include consumer payments on insurance premiums, mortgage loans, and other kinds of bills.  Debit transfers also include new applications such as the Point-of-Purchase (POP) check conversion pilot program sponsored by NACHA-The Electronic Payments Association.  Both the government and the commercial sectors use ACH payments.  Businesses are also increasingly using the ACH network to collect from customers online, rather than accepting credit cards or debit cards.
