Who fills out the purchase order?

The purchase order is a document initiated by a buyer that outlines the specifics of an order such as quantities, types of products or services requested, and agreed-upon prices. The primary party responsible for filling out and issuing the purchase order is the buyer, as they are the ones making the request for goods or services from the vendor.

In the procurement process, after the buyer determines the need for certain products or services, they will complete a purchase order to formally request these items from the vendor. The vendor then processes this order, confirming that they can fulfill the stated requirements. While vendors receive and confirm purchase orders, they do not fill them out themselves. Instead, they respond to the orders made by the buyers with confirmations or invoices after the purchase order has been issued.

Thus, the act of filling out the purchase order rests with the buyer, who is responsible for initiating the purchase transaction.
