A purchase order (PO) is a formal, legally binding document issued by a buyer to a seller, indicating the types, quantities, and agreed prices for products or services. In B2B transactions, purchase orders are fundamental to the procurement process, serving as both an authorization to buy and a reference document for receiving, invoicing, and payment.
Unlike a simple order confirmation, a purchase order carries legal weight. Once accepted by the seller, it becomes a binding contract that protects both parties by clearly documenting the terms of the transaction.
For B2B distributors, purchase orders are used both when buying from suppliers and when receiving orders from customers. Managing POs efficiently is critical for maintaining accurate records, preventing disputes, and ensuring smooth operations.
