美国生产库存控制协会（APICS）对PR, Contract，PO的定义

Purchase requisition

An authorization to the purchasing department to purchase specified materials in specified quantities within a specified time. See:

parts requisition.

Contract

An agreement between two or more competent persons or companies to perform or not to perform specific acts or services or to deliver merchandise . A contract may be oral or written.

A purchase order, when accepted by a supplier, becomes a contract. Acceptance may be in writing or by performance, unless the purchase order requires acceptance in writing

Purchase order

The purchaser's authorization used to formalize a purchase transaction with a supplier. A purchase order, when given to a supplier,

should contain statements of the name, part number, quantity, description, and price of the goods or services ordered; agreed-to

terms as to payment, discounts, date of performance, and transportation; and all other agreements pertinent to the purchase and its

execution by the supplier.

purchase order 与 contract有什么区别

合同法里达成合同的条件是有offer and acceptance. （提取要求及接受）。 你的purchase order 是个要求(offer) 对方要接受(accept)后才算是达成合同（contract). 接受你的purchase order可以用invoice, demand note 等文件表示。当然你们可以另外签一份协议agreement 或合同contract。
