Pro Forma Invoice: Definition & Overview

Learn what a pro forma invoice is, how it differs from a commercial invoice, and when to use one in your business.

KEY TAKEAWAYS

  • A pro forma invoice is a preliminary invoice sent before a sale, not a demand for payment.

  • Pro forma invoices are commonly used for international shipping customs clearance and customer quotes.

  • Unlike a commercial invoice, a pro forma invoice is not legally binding and is not used for accounting purposes.

What is a Pro Forma Invoice?

A pro forma invoice is a preliminary document that outlines the details of a potential sale before it is finalized. The term "pro forma" means "as a matter of form" in Latin, reflecting its purpose as a formal estimate rather than an actual bill. Unlike a commercial invoice, a pro forma invoice is not a demand for payment. Instead, it shows the buyer what they can expect to pay, including itemized costs, quantities, and any applicable taxes or shipping fees.

Pro Forma Invoice vs. Commercial Invoice

While both documents contain similar information, their purpose and legal standing differ significantly:

  • A pro forma invoice is sent before the sale as a quote or estimate. A commercial invoice is sent after delivery as a formal payment request.

  • A pro forma invoice is not legally binding and can be revised. A commercial invoice is a legally binding document that requires payment.

  • Only the commercial invoice is used for accounting, tax records, and revenue recognition purposes.

  • Pro forma invoices help buyers make informed decisions. Commercial invoices finalize the transaction for the seller's and buyer's records.

When to Use a Pro Forma Invoice

Pro forma invoices are used in many business scenarios:

  • Quotes and Estimates: Provide a detailed breakdown of costs so customers know exactly what they will pay before committing.

  • International Shipping: Customs authorities require pro forma invoices to assess duties and taxes on goods crossing borders.

  • Deposit Requests: Send a pro forma invoice for a deposit amount before issuing the final commercial invoice for the balance.

Is a Pro Forma Invoice Legally Binding?

No, a pro forma invoice is generally not a legally binding document. It is a preliminary estimate that outlines the anticipated costs of a transaction. The terms and prices shown on a pro forma invoice can be negotiated and changed before the final commercial invoice is issued. However, if both parties sign a pro forma invoice, it may be considered a contractual agreement depending on the jurisdiction. Always include a clear validity period on your pro forma invoices to indicate how long the quoted prices remain in effect.

What to Include in a Pro Forma Invoice

A well-prepared pro forma invoice should include the following information:

  • Seller's business name, address, and contact information

  • Buyer's business name, shipping address, and contact information

  • A unique pro forma invoice number and issue date

  • Detailed description of goods or services, including quantities and unit prices

  • Subtotal, taxes, shipping costs, and total estimated amount

  • Payment terms, validity period, and a clear "Pro Forma Invoice" label

Best Practices for Pro Forma Invoices

Follow these best practices when creating pro forma invoices:

  • Always label the document clearly as "Pro Forma Invoice" to avoid confusion with a final bill.

  • Include a validity date so the quoted prices are time-bound and can be updated if costs change.

  • Use invoicing software to automate pro forma invoice creation and track when customers accept or request changes.

  • Keep a record of all pro forma invoices issued, as they may be referenced when creating the final commercial invoice.

Summary

A pro forma invoice is an essential business document that serves as a preliminary quote before a transaction is finalized. It helps customers understand costs, facilitates international shipping through customs clearance, and provides a professional framework for negotiating terms. While it is not a legally binding payment request, it sets clear expectations for both parties before the commercial invoice is issued.

Using invoicing software like Otto makes it easy to create professional pro forma invoices, convert them to commercial invoices when the deal is closed, and manage the entire billing workflow from one platform.

Pro Forma Invoice FAQs

Quick answers to common questions about pro forma invoices

What is a pro forma invoice?

A pro forma invoice is a preliminary document that outlines the details of a potential sale. It is not a demand for payment but serves as a quote or estimated invoice that shows the buyer what they will pay before the final commercial invoice is issued.

What is the difference between a pro forma invoice and a commercial invoice?

A pro forma invoice is sent before a sale as a preliminary quote and is not a demand for payment. A commercial invoice is the final bill sent after goods or services are delivered and requires payment. Only the commercial invoice is used for accounting and tax purposes.

When should I use a pro forma invoice?

Use pro forma invoices when providing customer quotes, shipping goods internationally for customs clearance, requesting deposits before starting work, presenting project bids, issuing trial period statements, and documenting costs for import processing.

To create a pro forma invoice, include your business name and contact details, the buyer's information, a unique pro forma invoice number, description of goods or services, quantities and unit prices, total estimated amount, payment terms, and a validity date.
