What is the difference between a purchase order and an invoice?
purchase order :
A purchase order (PO) is a document issued by a buyer to a seller, indicating the types, quantities, and agreed prices for products or services that the seller will provide to the buyer. It serves as a formal request for the purchase of goods or services and contains important details such as the PO number, date of issue, buyer and seller information, item descriptions, quantities, prices, delivery dates, and payment terms.
The purpose of a purchase order is to establish clear communication and formalize the agreement between the buyer and seller. It provides a record of the transaction and serves as a reference for both parties to track the status of the order. Additionally, a purchase order helps the buyer control spending by specifying the approved budget for the purchase and prevents unauthorized purchases. Overall, a purchase order plays a crucial role in the procurement process by ensuring that both parties are in agreement regarding the terms of the transaction.
Invoice
An invoice is a commercial document issued by a seller to a buyer, indicating the products, quantities, and agreed prices for goods or services provided. It serves as a request for payment and includes payment terms, such as the due date and acceptable payment methods. Unlike a purchase order, which is issued by the buyer to initiate a purchase, an invoice is issued by the seller after the goods or services have been delivered or completed.
Invoices are essential for accounting and financial record-keeping purposes, as they provide a detailed summary of transactions between a buyer and a seller. They help track payments, monitor accounts receivable, and facilitate the reconciliation of accounts. Invoices also serve as legal documents that establish an obligation on the part of the buyer to pay the seller for the goods or services provided.
