The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.

1. Method for operating an account payable computing system, comprising the steps of:
preprocessing electronic invoices received from a vendor to identify duplicate invoices;
introducing invoices not identified as duplicate invoices into an accounts payable data base; and
rejecting invoices identified as duplicate invoices back to said vendor without introducing said duplicate invoices into said accounts payable data base.
2. A method for operating a computing system, comprising the steps of:
grabbing an inbound EDI invoice file from a vendor before it is input to an accounts payable database;
