Automated Clearing House (ACH) transactions are a widespread method for transferring funds electronically between banks and credit unions in the United States. This system is used for various types of payments, such as direct deposits, bill payments, and business-to-business transactions. Most banks and credit unions in the U.S. participate in the ACH network, making ACH transactions a standard service offered to customers.
If your bank account does not allow ACH withdrawals, you will need to link a new bank account from your account settings.
