Purchasing Narrative After the Purchasing Clerk receives the purchase requisition, Clerk will determine where to buy the product. If the item has been ordered previously, then the Clerk will select a vendor from the approved vendor list. If it has not been ordered previously, the Clerk will use a competitive bidding process to determine the vendor. Once the vendor is selected, a purchase order is prepared and sent to the vendor. Other copies are sent to Accounts Payable and the originating department. A fourth copy is filed in the Purchasing department, and a fifth copy has quantities omitted and is sent to Receiving. After the order is received, the vendor will send an invoice. When the invoice is received from the vendor it is reviewed by the Purchasing Clerk and approved by the Purchasing Manager. The approved invoice is sent to Accounts Payable along with the purchase requisition
