Operations Management and Information Systems (OMIS) 320 Exam 1 Practice Test

A purchase order represents the buyer’s formal offer to purchase specific goods or services under agreed terms. It details what is being bought, in what quantities, at what price, and delivery expectations. It becomes a binding contract only when the supplier accepts the offer, at which point both sides are obligated to the specified terms. Until acceptance, there is no contract. This distinguishes a PO from an invoice (the supplier’s request for payment after delivery), a shipping document (which accompanies and tracks the physical goods), and a payment voucher (which authorizes payment).
