In these cases we will wait for the invoice to be sent to Accounting for payment. Departments will no longer need to send copies of the requisition. The department copy is on the computer. Note that there is a cross reference between the requisition number and the PO number. When sending invoices, etc. to Accounting, attach small pieces of paperwork carefully.
Accounting still requires two copies of invoices for payment.
Most vendors now provide multiple copies of their invoice. Department's copy of the purchase order is on the computer. If a copy of the PO is required for some special reason, advise Purchasing and one will be sent to you.
