A Quotation Purchase Order (QPO) is an official business document that is used to formalize the purchase of goods or services. It is issued by the buyer to the seller and includes details such as the quantity and price of the goods or services being purchased, the delivery date, payment terms, and any other special instructions. The QPO is a legally binding document and serves as an agreement between the buyer and seller. It is important to note that the QPO is not a sales order or an invoice. A sales order is a document that is issued by the seller to the buyer, while an invoice is a document that is issued by the seller to the buyer after the goods or services have been delivered. The QPO is a document that is issued by the buyer to the seller prior to the goods or services being delivered. The QPO is an important document as it serves as a form of assurance that the goods or services will be delivered as specified and that payment will be made in accordance with the agreed upon terms.
