What is a Blanket Purchase Order?

A blanket purchase order is a contractual arrangement between a buyer and a supplier, for the supplier to deliver goods or services to the buyer, at a pre-set price, for a period of time. They are used by buyers to consolidate a number of smaller purchase orders into one large purchase. A blanket purchase order works best when dealing with recurring purchases from the same supplier over an extended period of time. It is not useful when the price, quantity needed, or product quality are variable.

When using a blanket purchase order, the buying entity should monitor the quantity ordered over the term of the agreement. This is done to ensure that the promised purchase amount is actually ordered, and to know when the total commitment amount has been ordered, so that a new agreement can be negotiated.

Advantages of Blanket Purchase Orders

There are several advantages associated with the use of blanket purchase orders, which are as follows:

  • Less paperwork. There is much less work involved in preparing a single blanket purchase order and subsequent releases against that order than in preparing a number of separate purchase orders.

  • Can trigger volume discounts. When a blanket purchase order is for a large number of units, it can trigger a volume discount from the supplier.

  • Reduces the number of suppliers. The buyer can centralize its purchases with a relatively small number of suppliers, which reduces the amount of time that would otherwise be required to negotiate prices and other terms with a larger number of suppliers.
