Wondering about the difference between a pro forma and a regular invoice—or when to use a pro forma invoice? You’re not alone. 

Like all invoices, a pro forma invoice outlines a sale between a buyer and a seller—but there’s more to it than meets the eye. While it resembles a regular invoice, a pro forma invoice serves a distinct purpose and can’t be used interchangeably with standard invoices. 

Understanding the key distinctions is important for managing your accounts payable and avoiding costly mistakes. This article covers everything you need to know. 

Pro forma invoice meaning 

A pro forma invoice is an estimated invoice that you send to the buyer before delivering the goods or services, asking for payment upfront. It lists what you’re selling, the total amount, and key details about the transaction. 

Looking at invoice definitions, a regular invoice is a document showing what’s owed for goods or services you have delivered. The pro forma version is essentially a “good faith” promise between you and the buyer, so they know what to expect. 

For example, if you need payment upfront to lock in financing before you can make the goods or deliver the service, a pro forma invoice lays out all these details before any work is done.  

It’s not an actual request for payment. It confirms some details while letting the buyer know of any other parts that still need to be finalized. In that sense, a pro forma invoice is closer to a quote or estimate than an invoice. 

Is a pro forma invoice legally binding? 

No, even though it includes many of the same details as a final sales invoice, a pro forma invoice doesn’t have the same legal power. You can’t use it for accounting or as a binding contract. 

Your customer doesn’t have to pay what’s listed, and it won’t show up in their accounts payable or your accounts receivable. 

Can a pro forma invoice be canceled? 

A pro forma invoice is just a preview of a potential transaction based on what your buyer has ordered, so cancellation isn’t necessary.  

What is a pro forma invoice used for? 

Pro forma invoices help both buyers and sellers understand the terms of the agreement, including pricing, items, and delivery details. It’s not a demand for payment, but can form the basis for agreeing on prices and terms.  

Why do businesses use pro forma invoices? 

Issuing a pro forma invoice means you’re giving your buyer a heads up about what to expect in terms of cost, delivery, and other details, like commission. It keeps things clear and can help prevent surprises or disagreements down the line, once the goods or services are delivered.  

These types of invoices have various use cases, including for manufacturing businesses that sell custom orders and businesses that need to get orders passed through international customs. 

Pro forma invoices are good for custom orders, as they make your buyer aware of how much their requested item will cost upfront before production starts. 

When should a business send a pro forma invoice? 

You should send a pro forma invoice when an order is placed, well before shipping. 

It’s a way to confirm the details and pricing upfront and avoid having to go back and forth later. It’s especially useful if you’re dealing with international shipments. 

What’s in a pro forma invoice? 

A pro forma invoice is packed with information. Here are the details of what makes up this preliminary document: 

  • Detailed descriptions of the goods: this means the country of origin and the product classification. (Think the Harmonized System or Schedule B number that U.S. Customs uses for figuring out duties and taxes.)  
  • Price of the products: how much are you charging?  
  • Delivery terms: where’s the package coming from, and where’s it going? When can the customer expect delivery?  
  • Validity or expiration date: how long is the stated price good for?  
  • The term “pro forma invoice”: let the buyer know it’s just a preview, not the final bill.

Pro forma invoice example 

As an example of a pro forma invoice in action, imagine you work for a veterinary group and get an order for 1,000 pet care packages. Instead of jumping straight into packing, you send a pro forma invoice with the price, delivery date, payment terms, and any discounts. 

This lets the buyer check the details and negotiate if needed. Once everyone’s on the same page, you finalize the pro forma, start packing, and then send the actual invoice. It’s a smoother way to handle orders and avoid mix-ups at the last minute.

What are the benefits of using a pro forma invoice? 

Using a pro forma invoice offers several key benefits for both buyers and sellers. Here’s why you may want to use one: 

  • Transparency: it’s like a clear window into the deal, showing both sides exactly what’s agreed upon.  
  • Streamlines sales process: it makes things smoother between the seller and buyer before the purchase is locked in. There will be less back and forth and more getting things done. 
  • Tool for negotiations: since it’s not a final bill, both sides can use it to tweak terms or make changes to the order.  

Disadvantages of a pro forma invoice 

While pro forma invoices have their perks, they’re not without their downsides:  

  • Potential for misunderstanding: customers might get confused and think it’s the actual invoice. This could lead to payment mix-ups. 
  • Absence of legal weight: these aren’t legally binding, so you can’t force your customer to pay just because you sent one. If a buyer backs out, you could lose out if you’ve already started making the products/working on the services.  
  • Possible changes in final cost: the pro forma might not match the final bill if costs or taxes change, potentially leading to arguments about what’s actually owed. 

Pro forma invoice versus invoice 

Let’s look at the difference between a pro forma invoice and a regular invoice. This will also give you an idea of how to write an invoice that really works. 

 Pro forma invoice Invoice  
Purpose Preview of terms and costs Final request for payment 
Legally binding  No Yes 
Uses Early estimate, pre-sale negotiation Final sale confirmation, payment request 
Flexibility  Can be adjusted before final deal Fixed and final. No changes allowed 

Pro forma invoice versus commercial invoice 

Pro forma invoices are useful for international trade too. U.S. Customs often needs them before you send out the real commercial invoice. 

 Pro forma invoice Commercial invoice  
Purpose  Initial estimate, not a demand for payment Official document for payment and customs 
Legally binding No Yes 
Use case Pre-sale, negotiation, or customs guess Final sale, payment collection, US customs 
Detail level Can be much less detailed Must include detailed transaction info 

Pro forma invoice versus purchase order 

A pro forma invoice is a preview of costs and terms, while a purchase order is a formal request from the buyer to buy something. Here’s how they differ. 

 Pro forma invoice Purchase order 
Purpose Estimate and terms preview Buyer’s formal request to purchase 
Legally binding No Yes, once accepted by seller 
Use Inform buyer of costs and terms Confirm what buyer wants to buy 
Initiator  Seller’s document Buyer’s document
