Blanket P.O.
A blanket purchase order (PO) is a type of contract issued by a buyer to a seller, authorizing the seller to supply certain goods or services over a period of time. The buyer typically issues a PO when it anticipates needing the goods or services on an ongoing basis, but doesn’t want to commit to ordering them in large quantities or at fixed intervals.
A blanket PO may be open-ended, meaning there’s no specified end date, or it may be valid for a set period of time. The terms of the contract will vary depending on the agreement between the buyer and seller.
