Allday Consulting's Peachtree and QuickBooks Support Boards

Hi: I have QuickBooks 99 on a Windows 98 computer and recently created a new set of 45 day payment terms for a new customer (Lists > Customers > Jobs > Edit). But every time I preview or print out the invoice it shows the due date as the invoice creation date, not the date 45 days from the invoice creation date. Can you help me?
