Within an organization, the term order may be used to refer to a work order for manufacturing, a preventive maintenance order, or an order to make repairs to a facility.
In many businesses orders are used to collect and report costs and revenues according to well-defined purposes. Then it is possible to show for what purposes costs have been incurred.
There are five basic requirements for a contract to exist between two parties: agreement, voluntary, consideration, capacity, and legality. A sixth requirement of "in writing" sometimes applies.
The main concern for commercial orders is that there must be agreement (offer and acceptance) for the order to be a contract. Prior to this, businesses often record the details of negotiations by using a request for quotation, request for bid, sales quotation, or sales bid. Quotations are non-binding and part of the negotiation process. A request for bid can be binding or non-binding, depending on the terms of the bid.
Once an agreement or contract is in place, businesses record these as confirmed purchase orders and confirmed sales orders.

(1) In this Article unless the context otherwise requires "contract" and "agreement" are limited to those relating to the present or future sale of goods. "Contract for sale" includes both a present sale of goods and a contract to sell goods at a future time. A "sale" consists in the passing of title from the seller to the buyer for a price (Section 2-401). A "present sale" means a sale which is accomplished by the making of the contract.
