Do you realize how much information is available regarding your merchant account? Not only does each monthly statement list the items that were purchased and the prices for which they were sold, the all important Item Number (UPC) is usually recorded also.
This means that your monthly statement is an assistant to the all-important task of keeping track of inventory. How many did the customer buy? Which ones? Now you can keep track of what that customer likes and have a better idea of which ads to send her way.
It also means that when your customer calls and asks what #2221114744555 is on his statement, you can easily tell him which product he purchased, easing his mind regarding an overcharge, or alerting you quickly to an error that you can rectify.
