Po stands for Purchase Order. It’s an official document issued by a buyer to a seller indicating the type, quantity, and agreed-upon price of goods or services that are to be provided. A purchase order also helps lay out important terms such as payment schedule, delivery dates, taxes, and more. In short, it is a formal agreement between two parties that serves as a guide for doing business together. Po is essential for all commercial transactions and helps ensure that nothing falls through the cracks when conducting business.
