I checked my account statement. I pay Authorize as follows:
- $20 monthly Customer Information Manager fee. The "CIM" lets them legally store all the customer's card info, allowing me to charge their card any balances due later. I never see their whole card number. Authorize handles meeting all government security requirements. You don't HAVE to use CIM, but I do just so it's all legal and I don't have to keep up with things.
- $20 Payment Gateway Acccount fee
- + 10 cents/transaction
- + 25 cents/batch
In my case, all the above costs me about $50/month. Sometimes less, sometimes a little more, depending on number of charges processed that month..
