What is PO/PI?

PO/PI refers to Purchase Order/Purchase Invoice. It is a common term in business-to-business (B2B) transactions and electronic data interchange (EDI). A Purchase Order (PO) is a document sent from a buyer to a seller, expressing an intention to purchase goods or services. A Purchase Invoice (PI) is a bill presented by the seller to the buyer requesting payment for the goods or services provided. In the context of technology, PO/PI often appears in discussions of procurement systems, supply chain management software, and accounting systems that automate and manage the creation, processing, and reconciliation of these documents. These systems aim to streamline the purchasing process, reduce errors, and improve efficiency.
