Before diving into blanket purchase orders, let’s define a purchase order. A purchase order is simply a document that a buyer sends to a supplier to request goods or services, which outlines the order’s details, including the quantity, price, delivery, and payment terms. 

A purchase order plays a vital role in a transaction as it provides clarity and protection for both parties. It becomes a legally binding agreement between the purchaser and the vendor once accepted by the latter.

Using a purchase order is essential for several reasons. First, it ensures clear communication between the buyer and the supplier, eliminating potential misunderstandings or disputes. It also helps to ensure that the buyer receives the goods or services they requested on the agreed terms and conditions. 

Additionally, a PO can help streamline the procurement process, making it more efficient and cost-effective. Lastly, it facilitates accurate accounts payable processes, ensuring that payments are made correctly and on time.

What isa Blanket Purchase?

A blanket purchase order (BPO) is a type of purchase order used when a buyer has recurring purchases over some time. Usually, it is used in transactions involving multiple payments for the same products or services. 

Issuing a BPO is an efficient way to save time, prevent processing delays, and allow the administration to focus on other essential things and streamline the procurement process, as the blanket purchase order already stated the details needed to be filled out.

When to Usea Blanket Purchase Order?

Based on the table above, a blanket purchase order is best suited to be used for situations or transactions where there is a continuous need for goods or services from a specific vendor. BPO is commonly used for goods with stable demand or when long-term supplier relationships are established. Some common examples of when to use a BPO include:

        • Standing orders for office suppliers or other consumables
        • Regular maintenance or service contracts
        • Open orders for raw materials

Manufacturing, maintenance, and service-based business are industries that find blanket purchase orders beneficial to use. 

How to Createa Blanket and Regular Purchase Order?

Creating a BPO and a PO follows the same process. The only thing that differentiates a BPO from a regular PO is that BPO is treated as a long-term contract between a business and the supplier, whereas a regular PO is an agreement for a one-time project. 

Here are the steps to create both types:

        • Identify the goods or services that will be purchased regularly.
        • For PO, always select a supplier who can meet your requirements for your specific needs. For BPO, you can skip doing this as you have already established a relationship with a supplier.
        • Determine the agreement’s quantity, price, delivery date, and payment terms.
        • Draft BPO that outlines the terms and conditions of the agreement. Draft the PO that outlines the details of the order.
        • Send the BPO and PO to the supplier for review and acceptance.
