Purchase Order vs. Invoice: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
A Purchase Order (PO) is a buyer's formal request to a seller for goods or services, while an Invoice is the seller's request for payment for those goods or services.
Key Differences
A Purchase Order is a document issued by a buyer to a seller, indicating types, quantities, and agreed prices for products or services. In contrast, an Invoice is issued by the seller to the buyer, detailing the goods or services provided, and requesting payment.

The Purchase Order serves as an official offer and a legal document that binds the buyer to pay for the ordered goods or services. Conversely, the Invoice serves as a billing document, representing a legal claim for payment from the seller to the buyer.

The process begins with the Purchase Order, which starts the transaction and outlines the buyer's needs and terms. In response, the Invoice is generated after the transaction is completed, summarizing what the seller has provided and the amount due.
