Using the ACH (Automated Clearing House) system offers several solutions. Not only can a merchant move funds to and from other accounts, but they can also pay out affiliates. Using ACH for an Affiliate Program is beneficial because it acts as a system of several ACH merchants processing under one account. ACH administrators can payout or conveniently collect funds from each of the affiliate merchants under their account. Administrators can also collect a percentage of each transaction that goes on under their account.
