Which document is commonly associated with supply chain agreements between suppliers and buyers?

The purchase order is a critical document in supply chain management that formalizes an agreement between a supplier and a buyer. It serves as a legally binding contract that outlines the specific details of a transaction, including the products or services being purchased, the quantities, prices, delivery dates, and payment terms. This clarity helps prevent misunderstandings between the parties involved, as it records the explicit intentions and requirements of the buyer.

In the context of supply chain operations, the purchase order is vital because it initiates the procurement process and triggers the supplier's fulfillment actions. It becomes an essential reference point for both the supplier and the buyer throughout the supply chain process, ensuring that both parties have aligned expectations. This document also facilitates accurate tracking of expenditures and inventory levels, contributing to effective supply chain management.
