What is ACH?
ACH refers to the Automated Clearing House network in the United States. This electronic payment network processes bank-to-bank transfers in batches. Financial institutions use ACH for transactions such as payroll direct deposits, recurring bill payments, government benefit payments, and business transfers. The network forms a central component of the United States electronic payments infrastructure.
How does an ACH payment work?
An ACH payment begins when a business, government agency, or individual submits a payment instruction through their bank. The originating bank sends the payment request into the ACH network, where transactions are grouped into batches. The network routes the request to the receiving bank, which credits the recipient's account upon settlement. Processing often takes 1 to 2 business days, though same-day ACH processing is now available for many transactions.
What types of payments use ACH?
ACH supports many common payment types used by both businesses and consumers. Examples include payroll deposits, utility bill payments, subscription payments, supplier payments, tax refunds, and government benefits. Businesses favour ACH payments for recurring transactions because processing costs remain lower than most card payments.
What is the difference between ACH and wire transfers?
ACH transfers and wire transfers both move funds between bank accounts, although they operate differently. ACH payments process in batches and settle later, while wire transfers move funds individually in real time. ACH payments cost less and support recurring payments easily. Wire transfers settle faster and often support urgent or high-value transactions.
Are ACH payments secure?
ACH payments operate within a regulated network governed by NACHA, the organisation responsible for ACH rules and standards. Banks apply authentication procedures, monitoring systems, and transaction controls to detect fraud. While no payment method eliminates all risk, these safeguards help ensure secure electronic transfers across the US banking system.
