Proforma vs Commercial Invoice : What's the difference?

The world of international trade can be complex and full of intricate steps and details, especially when it comes to different types of documentation. Among the most essential documents in global transactions are proforma invoices and commercial invoices. 

One area that often raises questions is the difference between a proforma invoice and a commercial invoice. While both of these documents are essential components of international trade, it's important to understand their unique purposes, uses and roles in the import process.

In this guide, we’ll explore the distinctions between proforma invoices and commercial invoices, their functions, when they should be used and their importance in international trade.

Proforma Invoice - A Preliminary Document

A proforma invoice is a preliminary document provided by the seller (in this case, the Chinese supplier) to the buyer (importer or company) before a formal sale agreement is made. This document serves as an estimate of the goods and services being offered and typically includes information such as:

  • The seller's and buyer's company information
  • A detailed description of the goods or services
  • The quantity of items being supplied
  • The price per unit, currency and the total cost
  • Shipping and handling fees
  • The Incoterms (International Commercial Terms)
  • Payment terms and conditions
  • Any applicable discounts or additional charges
  • The proposed delivery date

The primary purpose of a proforma invoice is to give the buyer an idea of what to expect in terms of cost, delivery, and other aspects of the upcoming transaction. It is not a legally binding document, meaning that the terms and conditions outlined in it can be subject to change and negotiated before the final sale is made.

Commercial Invoice - A Binding Document

Unlike the proforma invoice, a commercial invoice is a legally binding document that serves as a record of the finalized sale agreement between the seller and the buyer. It is a crucial document that is required for customs clearance purposes and is an essential part of the international trade process. A commercial invoice typically includes:

  • The seller's and buyer's company information
  • A detailed description of the goods or services
  • The quantity of items being shipped
  • The price per unit, currency and the total cost
  • The Harmonized System (HS) code for each item
  • The Incoterms (International Commercial Terms) agreed upon
  • The terms of payment and any applicable discounts
  • Shipping and handling fees
  • The country of origin for the goods
  • The signature of the exporter (seller)

The commercial invoice is vital in calculating import duties and taxes, as well as ensuring that the goods being imported are legally compliant with the destination country's regulations. In the event of a dispute, the commercial invoice serves as evidence of the agreed-upon terms and conditions of the transaction.

Key Differences between Proforma and Commercial Invoices

Now that we have a clear understanding of the purpose and contents of each type of invoice, let's explore the key differences between them:

  • Purpose: A proforma invoice serves as an estimate or quotation for potential buyers to evaluate costs and make informed decisions, while a commercial invoice is a legally binding document that confirms the final sale and serves as a formal request for payment.
  • Legal status: A proforma invoice is not legally binding and can be subject to change during negotiations, while a commercial invoice serves as a formal record of the transaction, obligating the buyer to make payment as per the agreed terms and is required for customs clearance.
  • Timing: A proforma invoice is issued before the actual sale or delivery of goods or services, while a commercial invoice is issued after the agreement is reached by all parties involved and the goods or services are sold.
  • Contents: A proforma invoice simply provides an estimate of the goods and services being offered, while a commercial invoice includes finalized details, such as the HS code, Incoterms, legal company information for both parties and the exporter's signature.
  • Validity: Proforma invoices typically have a validity period, ranging from 30 to 90 days, as they are influenced by factors such as exchange rate fluctuations and variations in raw material costs. Whereas commercial invoices do not have an expiration date, as they serve as a finalized record of the transaction.
  • Financing: Buyers commonly use proforma invoices to obtain cost estimates, apply for letters of credit and to secure financing for their purchases, while commercial invoices do not typically play a role in financing arrangements.
  • Import restrictions: Some countries may require importers to submit proforma invoices in advance, due to import restrictions such as strict currency exchange rate control, the need for an import permit before entry, or the implementation of import quotas on certain types of goods to safeguard domestic industries.
  • Customs requirements: A proforma invoice has no direct role in customs clearance, while a commercial invoice is a mandatory and essential document, as it provides necessary information for customs authorities to determine import duties and taxes.
  • Negotiability: The terms and conditions in a proforma invoice can be negotiated and changed before the final sale, while a commercial invoice represents the agreed-upon terms that cannot be altered without mutual consent from both parties.

By understanding the differences and key uses between a proforma invoice and a commercial invoice, as well as the critical information they contain, importers can navigate the purchasing process more effectively and avoid potential pitfalls.

Practical Tips for Importers and Companies Dealing with Chinese Suppliers

Understanding the difference between a proforma invoice and a commercial invoice is essential for successful international trade transactions. To help you further, here are some practical tips for importers and companies purchasing products from Chinese suppliers:

  1. Request a proforma invoice: Before finalizing any transaction, always request a proforma invoice to get a clear idea of the cost, delivery and other aspects of the deal. This will help you make informed decisions and avoid any unpleasant surprises.
  1. Verify the accuracy of the proforma invoice: Ensure that the proforma invoice includes all necessary information, such as a detailed description of the goods or services, price, quantity, shipping cost, Incoterms and payment terms. Double-check these details and don’t be shy to request changes if necessary.
  1. Negotiate the terms: If the terms in the proforma invoice are not favorable or do not meet your requirements, be sure to negotiate with the Chinese supplier to reach a more favorable and mutually acceptable agreement.
  1. Finalize the transaction with a commercial invoice: Once you have agreed to the terms, request a commercial invoice from the supplier. Ensure that it includes all the finalized details, such as the HS code, Incoterms, company information for both parties and the exporter's signature.
  1. Familiarize yourself with customs requirements: Be aware of the customs regulations and requirements in both China and your destination country. This knowledge and due diligence will help you avoid potential delays and complications during the customs clearance process.

Frequently Asked Questions (FAQs)

Can a proforma invoice be used for customs clearance?

No, a proforma invoice cannot be used for customs clearance. A commercial invoice is the required document for this purpose, as it provides the necessary details for customs officials to calculate import duties and taxes, and ensure compliance with the destination country's regulations.

How can I ensure that the proforma or commercial invoice I receive is accurate?

To ensure the accuracy of the proforma or commercial invoice, carefully review all the information provided and if you find any discrepancies or missing information, communicate with the supplier and request changes or clarification as needed. It's essential for you as the buyer, to verify the accuracy of the proforma invoice before moving forward with the transaction.

What is the main difference between a proforma invoice and a commercial invoice?

The main difference between a proforma invoice and a commercial invoice is that a proforma invoice is not a legally binding document and is simply used to give the buyer an estimate of the cost of goods, while a commercial invoice is a legally binding document that’s used to formally request payment and primarily used in assessing duties and taxes during customs clearance.

Is a proforma invoice legally binding?

A proforma invoice is not a legally binding document, as it is only an estimate or a quote for goods or services. A commercial invoice, on the other hand, is a legally binding document used during customs clearance that provides a detailed description of the goods or services being sold, along with the price and terms of the sale.

Is a commercial invoice legally binding?

Yes, a commercial invoice is a legally binding document that is used to formally request payment from a buyer and the primary document that is used by customs officials to assess duties and taxes for incoming shipments.
