To browse customer files, you can either go to the browse menu and click on customer files or just simply press the F4 key.  You can look customers up three different ways.  The first way to look up customers is by their last name, second by customer number, and the third way is phone number, both of the last two options are in chronological order.  You can select a customer by double clicking on their file.  The next screen will be the customer information screen.  In this screen you can change any information, make or view notes, views all accounts that the customer has on file, and view all payments made by the customer.   While viewing payments made by the customer, you can click add new payment and it will pull up the new payment screen but with the entire customer’s information already there.  You just have to add the biller information, account number, and check number.
