Purchase Requisition vs Purchase Order

Key Takeaways:

  • Purchase Requisition vs Purchase Order: Purchase requisitions are internal requests within a company for goods or services, while purchase orders are external orders sent to suppliers to confirm a commitment to purchase.
  • Process Flow: Requisitions become purchase orders once approved, with requisitions used internally to track needs and purchase orders used externally to make purchases from designated suppliers.
  • Importance of Requisitions: Requisition orders optimize cost reduction by requiring multiple quotes from suppliers, ensuring the best quality products and prices are attained.
  • Key Differences: Purchase requisitions are internal orders indicating a need within the company, while purchase orders are external orders sent to suppliers, both crucial in the purchase-to-pay process and modern procurement solutions.

For someone new or unfamiliar with procurement and purchasing, the terms "purchase orders" and "requisitions" (also sometimes called "purchase requisitions" or "order requisitions") can come across as a bit confusing at first. They're both terms that can signify that goods or services need to be purchased by a company. They're also both an integral part of the purchase to pay (also referred to as P2P) process, which deals with identifying requirements, approving and placing purchase orders, and finally reconciling the received deliveries and billed invoices via a 3-way match.

If purchase requisitions and purchase orders have so much in common, then what's the difference?

Simply put, purchase requisitions eventually become purchase orders once those PO requisitions are approved. Purchase orders are sent to suppliers - not purchase requisitions.

What is Purchase Requisition?

Purchase requisitions are an indication that certain goods or services need to be purchased within a company. They're used by company employees to communicate the things they need purchased to those who are in charge of procurement. PO requisitions are internal orders, meaning that they never go outside of the company.

What are Purchase Orders?

Purchase orders are sent to suppliers or vendors to indicate an intent to purchase goods or services. Regardless of the size or specialization of a company, purchase orders commonly require verification from a manager to take place before they're sent to a supplier, similar to order requisitions. The main difference is that order requisitions, when received from employees, are used internally by purchase departments to track the goods and services they need to purchase, while purchase orders are tools for acting on those needs by making those purchases from designated suppliers.As an example of a basic chain of events leading up to a purchase order being sent, let's say a manufacturing plant is running low on a certain component needed to make its products, like metal bolts:

  1. An employee notices this and, not being the one responsible for making purchase orders, indicates that more metal bolts need to be purchased by submitting a purchase requisition to the warehouse manager.
  2. Once it's approved, the warehouse manager then submits the purchase requisition to the purchasing department for the second round of approvals.
  3. After verifying the expenditure, the purchasing manager populates the approved purchase order with the required quantity of metal bolts specified in the requisition order. (Sometimes this step is replaced with submitting an RFQ or an RFP if the buyer plans to negotiate with the supplier.)
  4. In larger companies, the purchase order may even be reviewed and approved one or more times before having the finalized purchase order sent to a supplier.

But just how important are purchase requisitions when creating a purchase process?

Why are purchase requisitions necessary?

Why not create purchase orders immediately when goods and services are needed?

These are good questions, and the answers can vary from company to company.One of the universal reasons is that requisition orders can be an important factor in optimizing the reduction of overall purchase costs. In the case of some companies and government agencies, multiple purchase quotes from different suppliers are a requirement on requisition orders, before the creation of a purchase order, to ensure that the best quality products and prices are attained from each order.However, this wasn't always the case. Some companies used to avoid using PO requisitions and purchase orders entirely. But why?In the past, when orders involved smaller amounts of money, foregoing both requisition orders and purchase orders in favor of making a purchase directly with a company credit card was a popular method used in the interest of saving time.However, with the introduction of e-procurement and online purchase order software, along with the ability to retroactively log expenses, even small orders and purchases can now be documented with ease.

As monetary amounts on purchase orders increase, having a system in place to filter the initial requisition orders and approve the finalized purchase orders before sending them starts becoming essential for documentation, especially for larger expenditures. For companies that make a large number of purchase orders each month, being able to control spending without hindering workflow is also a necessity.To continue saving time while maintaining the advantages of these systems, e-procurement and online purchase order systems have become a popular approach to handling all of the steps in the purchase order process, especially in larger companies.Another great interaction between purchase requisitions and purchase orders in a software environment is the ability to populate single purchase orders from multiple requisitions – an extremely handy feature for companies that deal with larger volumes of requisition orders.
