I didn't want to show the other reports, so I dropped the "Available Reports" list down to show what other reports ConSuite offers.

In this example, you enter an attendee's badge number (located behind the dropped-down list) and the attendee's purchases are displayed.  If the attendee has not purchased something, "PAID" will be replaced by a check box and "$0" will be replaced by the grand total of items not paid.  Simply check which items the attendee is paying for, click "check out", and a receipt will be created.  The receipt information will also be stored so you can print the receipt out later or check it for discrepancies at a later time.
