What is an ACH transfer?

An ACH transfer is the most common form of electronic money movement. Automated Clearing House (ACH) is a network that electronically processes transactions for financial institutions. These transfers typically take a few business days to process and for the money to be available in the receiving account. When you transfer funds from an account at one bank to an account at another bank over the internet or when you pay a bill online, you are likely completing an ACH transfer.
