What’s the difference between a purchase order and an invoice

The primary difference between a purchase order and an invoice is that a purchase order confirms an order while an invoice requests an order’s payment.

Finance departments in most businesses deal with purchase orders and invoices every day. In essence, this means that the two are crucial documents of the account payable process.

But, what’s the difference between a purchase order and an invoice? Well, by the end of this post, you’ll know the fundamental differences between the two. Most importantly, you’ll learn how manual purchase orders and invoices can harm your business and why you should switch to the electronic purchase process.

Let’s dive right into it. But, before we take the plunge, let’s get a couple of things out of the way.

What’s an Invoice?

An invoice is a time-bound commercial document sent to a buyer by a seller. It lists and records the transaction between the two trading partners. An invoice asks for payment of goods or services bought on credit. Generally, there are two types of invoices; paper and electronic invoices.

Paper Invoices – These are, well, paper-based. They come in print form and are sent via mail or dropped to the client’s physical address.

Electronic Invoices – These are available in a structured electronic format. They’re processed automatically and electronically. Electronic invoices are becoming increasingly popular as the business world adopts digital transformation.

What is a Purchase Order?

A purchase order (PO) is a commercial document sent from the buyer to a supplier confirming the order for products or services. Once the seller accepts the PO, he/she becomes legally bound by the document’s contract status. Likewise, if the buyer refuses to pay, the seller can seek legal redress guided by the document’s terms and conditions.

What Are the Differences Between a Purchase Order and an Invoice?

The primary difference between a purchase order and an invoice is that a purchase order confirms an order while an invoice requests an order’s payment.

Still, there are more differences as listed below.

Purchase Order

  • Initiated by the buyer
  • Received by the seller
  • Sent at the onset of an order
  • Indicates the day the purchase was made
  • Contains the name of the company buying the goods and services
  • Describes the amount of goods or services offered
  • Indicates the prices
  • Contains payment information, billing address, and purchase order number
  • Indicates the shipping address and the expected delivery date

Invoice

  • Initiated by the seller/vendor
  • Received by the purchaser
  • Sent after the completion of an order per the payment agreement
  • Contains date of purchase, name of buying company, and the quantity of goods/services ordered
  • Includes the invoice number and the seller’s contact information
  • Indicates credits and discounts as well as the payment schedule
  • Show the total amount due to the seller

What are the Similarities Between a Purchase Order and an Invoice?

Indeed, there are apparent differences between a PO and an invoice. However, the two documents are similar in several ways.

Legal Stand Point – A purchase order and an invoice are legally binding contacts. In essence, this means the seller and the buyer must fulfill the details of the documents. Either party can file a legal suit against the party that fails to meet the actions outlined in the documents. On top of that, both documents include mailing information, order details, and prices. The invoice shows the vendor’s contact information and the invoice number and any adjustment to the payment. It also includes the total amount owed to the vendor and the payment schedule.

Further, an invoice includes a PO number as a reference.

Why Use an Invoice for Business?

There are several reasons you should use an invoice in day to day operation of your business. These include;

  • An Invoice Allows You to Collect Money

The number one benefit of using an invoice is to enable you to get you paid on time. Keep in mind that most buyers will not pay you for goods or services delivered until you send them an invoice. Sure, you can call or send an email, but most will insist that you forward an invoice for record-keeping purposes on their end.

  • An Invoice Offers Transparency on Spending

You have to keep track of your business’s spending. Otherwise, it’ll be hard to know which direction the enterprise is heading.An invoice is a reminder of why you’re spending your money. With such insights, the accounting department can know how various departments are spending their money. That way, it becomes easy to cut unnecessary spending.

  • An Invoice Allows You to Manage Payments

An invoice contains the number of goods or services sold. It also shows the amount of money paid to date and the outstanding arrears. That information helps businesses take control of how they make payments.

Why Use a Purchase Order for Business

A purchase order is an essential business document, whether you’re a small outfit or a large organization. What follows is a rundown of the benefits of using a PO for business.

It Helps Define Expectations of Both Parties

Purchase orders allow buyers to define what they expect from sellers in clear terms. Besides, both trading partners can use the terms to instigate a suit if the set conditions aren’t followed.

It Helps Manage Orders

A purchase order allows the operation, accounting, and procurement departments to track incoming and pending deliveries. That way, they can trace and manage orders efficiently.

It Helps With Budgeting

You must have a budget for your business. A purchase order allows buyers to determine extra costs, such as transportation in advance, enabling them to spend reasonably.

It Is a Legal Document

You don’t need a formal contract to pursue a seller who doesn’t fulfill their obligation. A purchase order is a legally binding business document. Note – A purchase order only becomes legal after the seller accepts it.

It Helps in Auditing

Any serious business should do audits every financial year. With a PO in place, it becomes easy to conduct audits.

Invoicing and the Three-Way Matching Process

The purchase order vs. invoice comparison isn’t complete until we talk about the three-way matching process. So, what is the three-way matching process?

For starters, this is a process of comparing a PO against goods or services note against the supplier’s invoice. The comparison happens before paying for the invoice. The idea is to help determine if the invoice will be paid partly or wholly. It also helps ensure that only the correct invoice gets paid.

From the description above, three documents are essential to the process. These are;

  • Purchase orders
  • Invoices
  • Order receipts or packing slips

The exact process includes reviewing quantities, prices, and terms to ensure that the vendor fulfilled what was expected as per the terms of the purchase order. The buyer can refuse to pay in case of variation in pricing, quantities, or if there are damaged goods. Once the invoice undergoes the three-way process, the buyer can pay as per the vendor’s terms. The three-way process can help your business save money by double-checking information and highlighting inconsistencies before payment. It also helps strengthen buyer and seller relationships.

Why are we talking about the three-way process? That leads us to our next point.

How Manual Purchase Order and Invoicing Can Hurt Your Business

Make no mistake about it; the three-way matching process makes perfect sense.

On the downside, however, it is still a manual process. And guess what? Manual processes have no place in today’s digital business world.

Think of it;

Processing purchase orders and invoices manual is prone to poor budget control, inefficiencies, higher costs, and errors.

On top of that, manual purchase orders and invoicing can cause;

  • Lack of transparency
  • Delay in the purchase order processing cycle
  • Lack of compliance
  • Poor communication between the people involved

Do you know what the good news is?

You can switch to electronic purchasing and help your business escape the disadvantages of the three-way matching process.
