To look up a previous payment, there are two ways.  First way to look up payments is by going to the browse menu then clicking on browse payments or just simple press the f3 key.   Once on the browse payment screen you can look up previous payment three different ways.  The first way is by the transaction number, the second by date and lastly by the customer number.  If you highlight a customer, a gray box in the bottom left side of the screen will give you the biller name, customer name, check number, and date paid.  You can also make a new payment form this screen by pressing the F2 key.  By double clicking on the customer’s file, you will pull up the payment screen where the payment was paid.  At this screen you can mark the checks cleared, if it has cleared the bank.   You can also make or view notes in the customer’s file from this screen.
