A merchant account is one piece of your whole payment solution. In its simplest terms, it is a bank account that allows your eBiz to accept online credit cards and e-checks. At a specific time each day, your merchant account bank receives that day s completed transactions. They hold the money for several days or more to make sure all parties involved are satisfied. During this time, they also perform additional security checks. If no issues arise, the bank then wires the money into your business checking account.
