Changing "Receipt #" on invoices

Q: I don't like it to show the term "Receipt #" on the invoice forms, since it's not a receipt -- can I change that?

A: Go to Maintenance / Data Field Definitions / Transaction Fields, locate the Receipt # field and change the Normal Header to what you want  (in version 3.9 or later, change the Short Label and Report Heading).  Note that this will change it on all types of receipts, however, so you'll need to make it something generic like "Statement" or "Ticket #".
