Automated Clearing House (ACH) payments are electronic transactions processed in batches, offering cost-effectiveness and efficiency for various payment types, from direct deposits to bill payments. The ACH network has evolved since the 1970s to handle a growing volume of transactions, providing benefits like lower fees and reduced fraud risks, but it also has slower processing times compared to traditional credit card methods. Businesses considering ACH processing should evaluate their needs, potential advantages, and partner suitability, while adhering to regulatory standards.
