A purchase order authorizes the seller to ship and invoice the materials and services as specified. Purchase orders shall be written in a clear, concise and complete manner. This will prevent confusion and unnecessary correspondence with suppliers.
Purchase orders are issued only after a requisition has been submitted and approved by the purchasing agent and the finance officer. No purchase order will be issued until the finance officer has certified adequate funds and cash balances to make the purchase, except as otherwise mentioned.
Who Issues the Purchase Order
The purchasing department issues purchase orders, except as otherwise provided herein. The using departments will not enter into negotiations with suppliers for the purchase of equipment, supplies, materials, services, or other items, except under the emergency purchase procedures and as otherwise provided herein.
How Purchase Orders Are Handled
The purchase order is made from the approved requisition and is prepared in six copies: white, blue, yellow, pink, green and orange.
White copy is mailed to the vendor to be used as authority to furnish the city with the materials or services indicated.
Blue copy is sent to the finance officer and the account that handles the amount of the purchase order.
Yellow copy is sent to the department head making the request, to be held until the goods or services are received. Upon completion of the order or contract, the yellow copy will be signed and invoices and material receiving report attached. This copy is sent to the purchasing agent for discounting and processing for payment.
Pink copy is kept by the purchasing agent and filed as record of outstanding orders. When paid, the pink copy will be marked properly and put in a completed file in numerical order.
Green copy is the department copy and should be kept in each department's file for reference.
Orange copy is the acknowledgment copy and will be sent to the vendor along with the white copy. The vendor will sign and return the orange copy to the purchasing agent, confirming the order.
The purchasing department must initiate all cancellations and will issue a purchase order to the next best vendor or renew the purchasing process.
