In addition, extensive training is done by the Purchasing Department. Departments will no longer need to send copies of the requisition. The department copy is on the computer or may be printed by department if needed. Note that there is a cross reference between the requisition number and the PO number. When sending invoices, etc. to Purchasing, attach small pieces of paperwork carefully.
Accounting still requires two copies of invoices for payment.
Most vendors now provide multiple copies of their invoice. Purchasing only requires a computer requisition that would create the purchase order. The duration of this order will be the same as the University fiscal year. Three copies of the purchase order are printed. One copy goes to the vendor, one copy for the Accounting Department, and one copy remains in the Purchasing Department.
