What’s the Difference Between Purchase Order and Invoice?
If you are new to the procurement arena, you may have trouble differentiating between invoices and purchase orders. In fact, even procurement team members have multiple opinions and definitions about what constitutes each process.
Failing to catch up on familiar procurement terms could make you skim through important financial documents, missing the finer points that can negatively impact your organizational spend. You simply can’t afford to stay ignorant of the procurement process.
To help you understand these terms better, here are clear definitions of these two procurement terms, what each constitutes, and how they differ from each other.
What is a purchase order? what does it contain?
A purchase order (also known as a PO) is the official document sent by a buyer to a vendor with the intention to track and control the purchasing process. Once a vendor accepts the PO, it becomes a legally binding contract.
Purchase orders outline the list of items (goods and services) a buyer would like to purchase, order quantities, and agreed-upon prices.
A purchase order usually includes:
- PO number
- Date of purchase
- Buyer details
- Order information
- Payment terms
- Delivery address
What is an invoice? what does it contain?
An invoice is an official payment request sent by the vendor to their buyers once the order is fulfilled. It lists down the goods or service that have been delivered and specifies the amount of money that is owed.
Typically, an invoice contains invoice number, vendor information, credits/discounts availed, payment schedule/date, and total amount due.
Key differences between purchase order and invoice
The key difference is that a purchase order is sent by buyers to vendors with the intention to track and control the purchasing process. On the other hand, an invoice is an official payment request sent by vendors to buyers once their order is fulfilled.

Although they are quite similar, they have a few fundamental differences, which must be understood clearly.
Most often, the terms purchase order and invoice seem like synonyms. Although they have a number of differences, purchase orders and invoices have quite a few similarities:

- They play an integral role in optimizing spend
- They provide better visibility into the purchasing process

Why do companies need both purchase orders and invoices?
Although a purchase order or an invoice might feel like an added burden, as the demand for purchases increase and the buyer-seller relation continues to evolve, these financial documents help a business manage its purchases smoothly.
When it comes to a choice between purchase order vs invoice, you can’t just pick one–both documents are equally important. While invoices seem critical from a legal point, purchase orders offer the much-needed clarification and prevent conflicts.
No matter whether there are increases or decreases in demand, or if the purchasing process is complex or simple, using POs and invoices will eliminate mistakes in communication by setting explicit expectations of the items being purchased.
