The purchase order is the written evidence of a contract between the buyer and supplier for the purchase of goods or services at an agreed price and delivery date.1 The purchase order is a vehicle by which the buyer formalizes the contract with the supplier. It is the supplier’s authority to ship and charge for the goods specified in the order.2It is the purchaser’s commitment for the value of the goods ordered.3t is a legal document and must therefore contain all the elements of the contract.4It should cover clearly and precisely the essential elements of the purchase to be made in a manner that minimizes any confusion between the buyer and seller.5Most counties use preprinted forms that contain general instructions, standard terms and conditions (generally referred to as “boilerplate” and often printed on the back of the purchase order or on a separate preprinted sheet and incorporated by reference), and adequate space to fully define the specific agreement.6At a minimum, the purchase orderform may be used to describe the essential elements of description, quantity, and price of the goods or services to be purchased; purchase order date and number; supplier’s name and address; delivery date(s) and shipping information; payment terms and buyer’s name, and signature most organizations also include standard terms and conditions.7Special terms and conditions, detailed specifications and drawings, and additional supporting information and documents that are part of a particular procurement can be incorporated in the purchase agreement by reference on the purchase order.8
