At first sight a merchant billing statement might be a scary document to peruse. But as you take it apart, bit by bit, you’ll find that it’s a very complete record of all of the activity that took place last month in your merchant account.
Under the Fee/Charges category you will find a listing that goes something like this: Visa/MC/Discover Processing Fees, followed by a Summary of the Fees, which is the total that was charged. Next there are Card Association Fees, followed by Authorization Fees. After that you may find “Other fees” and then a Total of the Charges and Fees.
This is the section that you will want to study and analyze. Not every merchant account charges the same percentage and not all have each of the above listed fees.
