A purchase order purpose is essentially a binding document that outlines the conditions of an agreement between two parties – the buyer and seller – regarding a commercial transaction. It includes all of the relevant details such as the item(s) being purchased, the quantity, delivery location, payment terms, reference numbers, and more. The purchase order purpose provides both parties with an understanding of their obligations in the transaction and serves as legal protection in case there are any misunderstandings or disputes. It’s an essential part of doing business and is key to successful procurement management.
