What Is a Blanket Purchase Order?
A blanket purchase order (PO) is a long-term agreement with one vendor for recurring purchases over a set period. It allows you to place multiple orders under the same purchase order instead of creating a new one each time. Instead of issuing a new PO for every transaction, you release orders as needed under the agreement.
The BPO sets key terms upfront, including pricing, delivery expectations, and the timeframe, so you don’t need to renegotiate with each order. As orders are fulfilled, each invoice references the same PO number. That keeps records consistent and makes it easier to track orders, spending, and remaining balances.
A blanket PO covers multiple orders under one agreement, while a standard purchase order is used for a single order.
When to Use a Blanket Purchase Order
Use a blanket purchase order when you plan to make repeat purchases from the same vendor over time. You’ll usually see it in situations like these:
- You buy the same goods or services regularly from one vendor, so it makes sense to group orders under one agreement.
- Your demand is steady or easy to estimate, which helps you plan quantities over a set period.
- You can agree on pricing and terms upfront, so you don’t need to revisit details with each order.
- You place frequent orders and want to reduce admin work, without repeating the same setup each time.
- You have an established, reliable supplier, making a long-term agreement lower risk.
- You’re managing ongoing needs like supplies, materials, or services, where orders come up consistently.
For example, if you order office supplies every month from the same vendor, that’s a clear case for using a blanket purchase order. You can set one up quickly using a Legal Templates blanket purchase order.
A blanket PO may not be the best fit if demand is unpredictable, the vendor is untested, or prices may fluctuate. It works best when needs are steady, and the supplier is reliable.
What to Include in a Blanket Purchase Order
A blanket purchase order should make repeat buying easier to manage. You’ll use it to place multiple orders over time, so each detail should support repeat ordering without needing changes or approvals for every purchase. Make sure the agreement covers the following:
- Who the vendor is. Includes the supplier’s name, address, and contact details.
- What you’re buying. List the goods or services, prices, and rough quantities.
- How much you can spend. Set a total limit for all orders under the BPO.
- How long it lasts. Define the start and end dates of the agreement.
- Delivery and handling. Set terms that apply to all orders unless stated otherwise.
- Consistent pricing. Keep rates the same across every order under the BPO.
- How orders are placed. Explain that multiple orders can use the same PO.
With these terms in place, each order can follow the same structure and pricing without reapproval. That keeps spending within the set limit and avoids issuing a new purchase order for each transaction.
Track total spend against the set limit. If you exceed it, you may need to update the agreement or issue a new purchase order.
