Purchase order vs. invoice: understanding the key differences
When it comes to business transactions, navigating the processes of purchase orders vs. invoices is vital to keeping your operations in check. Both are essential documents that help keep track of the financial aspects of a purchase, but they serve different purposes.
While a purchase order is issued by a buyer to initiate a purchase, an invoice is a request for payment from the seller for goods or services rendered.
Understanding the differences between purchase orders vs. invoices is crucial for managing business finances efficiently and effectively.
Take a closer look at purchase orders vs. invoices and explore their individual roles in the procurement process.
Defining a purchase order
A purchase order is a document created by a buyer and given to a seller, which outlines the details of the order, including the quantity and types of products, payment terms, and delivery details.
It serves as a contract between the two parties, with the buyer committing to purchasing the goods or services for the agreed-upon amount. Unlike a purchase requisition, a purchase order is a legally binding document that provides the seller insurance against non-payment since the order is filled before the buyer receives the bill.
What information should be included in a purchase order?
When setting out to create a purchase order, you must make sure that it includes critical information via online software or simply via Microsoft Word, Excel, or any other tool your company might use. Your purchase order should include the following:
- Issue date
- Products needed and the quantity of each product
- Product details, including SKU numbers, model numbers, and brand names
- Price of each product per unit
- Delivery date
- PO number
- Business information (shipping and billing address, company name, and contact)
- Terms of payment
What is the purpose of a purchase order?
The primary purpose of a purchase order is to formalize the purchasing agreement between the buyer and seller and establish the terms and conditions of the transaction. A purchase order:
Creates a record of the transaction
A purchase order serves as a legally binding agreement between the buyer and seller, creating a transaction record that can be used for future reference.
Provides clarity on the terms of the transaction
A purchase order specifies the details of the products or services being purchased, including quantity, price, delivery date, and other terms and conditions.
Helps manage inventory
A purchase order helps the buyer keep track of the items they have ordered and the expected delivery date, making it easier to manage inventory levels.
Streamlines the purchasing process
By providing a standardized document for ordering products or services, a purchase order streamlines the purchasing process and reduces the risk of errors or misunderstandings.
Enables tracking and accountability
A purchase order enables both the buyer and seller to track the transaction's progress and hold each other accountable for meeting their respective obligations.
Why is a purchase order important for my company?
A purchase order is essential for any company that regularly purchases goods or services from suppliers. Here are some reasons why a purchase order is important for your company:
Boosts your team efficiency
Implementing a PO system requires effort, but it offers long-term benefits. The system simplifies procurement with vendor-specific catalogs and automatic purchases. Purchase orders also streamline deliveries or pickups by matching received items with the PO.
Establishes clear expectations
A purchase order helps establish clear expectations between your company and your suppliers regarding the products or services being purchased, the quantity, delivery dates, and the agreed-upon price.
Helps to control costs
A purchase order helps you set limits on how much money can be spent on a specific purchase. This can help prevent overspending and ensure that your company only purchases what it needs.
Suppose you are embarking on a project. In that case, you can estimate the total cost of completing it by calculating the cost of the necessary materials at their required quantities.
Improves record-keeping
A purchase order provides a written transaction record, making tracking purchases, inventory levels, and supplier performance easier.
Assists with inventory management
A purchase order system simplifies inventory management by tracking incoming items and their quantities. Matching physical inventory with the purchase order and invoice makes maintaining inventory records easier, particularly during audits.
Helps resolve disputes
In case of any dispute between your company and your suppliers, a purchase order serves as evidence of the agreed-upon terms and can help resolve any conflicts.
Streamlines the purchasing process
A purchase order streamlines the purchasing process by creating a standardized document that your company can use to order goods and services from suppliers, reducing the risk of errors or misunderstandings.
Provides legal protection
Purchase orders act as sales contracts, including purchasing terms that safeguard buyer rights and seller obligations. POs can help address issues like incorrect deliveries and protect against unexpected price increases, strengthening buyer-supplier relationships.
Using purchase orders can help your company manage purchasing activities more efficiently, reduce the risk of errors or misunderstandings, and improve your relationships with your suppliers.
Defining an invoice
What is an invoice?
An invoice refers to a commercial document issued by a seller to a buyer that indicates the products or services provided, the quantity, the agreed-upon price, and the payment terms. It is a request for payment for the products or services that the seller has provided to the buyer.
Why is an invoice important for my company?
An invoice is an essential document for any company that sells products or services to customers. Here are some reasons why an invoice is important for your company:
Payment request
An invoice is a request for payment from your customers for the products or services you have provided. It establishes the amount owed, payment terms, and due date, which helps ensure that you get paid on time.
Record-keeping
An invoice provides a record of the transaction, including the date of sale, the products or services provided, and the amount charged. This information is important for accounting and tax purposes. It also helps you keep track of your sales and revenue.
Customer communication
An invoice is a form of communication with your customers, providing them with important information about the transaction. It can also serve as a reminder to your customers to pay their outstanding balances.
Payment tracking
By tracking the payment status of your invoices, you can manage your cash flow more effectively and identify potential issues with late or unpaid invoices.
Dispute resolution
In case of any disputes with your customers, an invoice serves as evidence of the agreed-upon terms of the transaction, helping to resolve any conflicts.

What is the difference between an invoice and a purchase order?
The main difference between a purchase order vs. an invoice is that they occupy different functions in a business transaction. Here are some of the keys differentiators for purchase orders vs. invoices:
Purpose
A purchase order is used by the buyer to initiate a request for goods or services from the seller, while an invoice is used by the seller to request payment for the goods or services they have provided.
Timing
A purchase order is typically issued before the goods or services are provided, while an invoice is issued after the goods or services have been delivered.
Content
A purchase order typically includes details such as the description of the goods or services, the quantity, the agreed-upon price, and delivery dates. An invoice, however, includes details such as the description of the goods or services provided, the quantity, the unit price, and the total amount due.
Legal status
A purchase order is a legally binding agreement between the buyer and the seller, while an invoice is a payment request and does not create a legal obligation on its own.
Payment
A purchase order does not involve any payment, while an invoice serves as a request for payment for the goods or services provided.
While both documents are essential in a business transaction, a purchase order initiates a request for goods or services, while an invoice is used to request payment for the goods or services provided. The two documents have different purposes and are issued at various times during the transaction.
What do purchase orders and invoices have in common?
Purchase orders and invoices have some similarities that sometimes cause confusion. These can include:
Reference numbers
Both purchase orders and invoices typically include a unique reference number that helps identify and track the transaction.

Both documents include the price per unit of the goods or services being requested or provided.

Business information
Both documents typically include information about the seller and buyer, such as their names, addresses, and contact information.
