What is a Proforma Invoice Number?

Carolyn Jul 11, 2026

A proforma invoice, often abbreviated as PFI, is a preliminary invoice sent to a customer before the goods or services have been delivered. It outlines the details of the transaction, including the products or services to be provided, their quantities, prices, and other relevant information. A proforma invoice is typically used for customs clearance, purchase orders, or as a quote. However, it's crucial to understand that it's not a final bill and doesn't obligate the customer to pay.

Proforma invoice numbers are typically sequential, meaning they follow a specific order or sequence. This sequential nature helps in maintaining a chronological record of all proforma invoices issued by a company. However, the format of these numbers can vary greatly depending on the company's internal accounting or ERP system.

The format of a proforma invoice number can be as simple as a sequence of numbers (e.g., 00001, 00002, 00003) or as complex as a combination of alphanumeric characters (e.g., PFI-2022-001, PFI-2022-002). Some companies may include the year of issuance in the number (e.g., PFI-2022-001), while others may not. The key is to maintain a consistent format that allows for easy tracking and identification.

Some companies may also include additional information in the proforma invoice number, such as the department or cost center code, to facilitate better tracking and allocation of costs. For instance, the number might look like this: PFI-2022-IT-001, where 'IT' represents the information technology department.

It's also a good idea to use automated systems for generating proforma invoice numbers. This not only ensures consistency but also saves time and reduces the risk of errors. Many accounting and ERP systems have built-in features for generating sequential, unique invoice numbers.
