A pro forma invoice is a preliminary bill of sale sent to a buyer in advance of a shipment or delivery of goods or services. Unlike a final sales invoice, it is not a demand for payment but a commitment to provide goods or services at an agreed-upon price. Based on our assessment experience, these documents are critical for international customs, internal budgeting, and setting clear expectations with clients, particularly for freelancers and businesses engaged in global trade.
The core purpose of a pro forma invoice is to provide a detailed financial preview. It acts as a quotation in an invoice format, outlining the specifics of a transaction before it is finalized. This is essential for several key business functions. For the buyer, it confirms the exact costs, allowing for internal approval processes and budget allocation. For the seller, it formalizes the agreement and minimizes future disputes. Crucially, in international trade, customs authorities require a pro forma invoice to assess duties and taxes on goods before a final commercial invoice is issued, even if payment hasn't been made.
Pro forma invoices are versatile tools applied across various business contexts. Their usage depends heavily on the transaction's nature and the parties involved.
For International Customs Clearance When shipping goods overseas, customs officials need a detailed description of the items to calculate import/export duties. A pro forma invoice fulfills this requirement by listing the goods, their value, and quantity. For example, if a U.S. manufacturer ships a sample batch of products to a potential distributor in Germany without immediate payment, the pro forma invoice accompanying the shipment allows customs in both countries to process the goods based on their declared value.
For Freelancers and Service Providers Freelancers often use pro forma invoices to outline project scope and costs before commencing work. This practice, akin to a detailed project proposal, ensures both parties agree on the deliverables and price, reducing the risk of billing disputes. It clearly states what is included in the quoted price and may outline potential additional costs for revisions or scope changes.
For Internal Business Approvals Within a company, a pro forma invoice can be part of an internal procurement process. An employee might need one to get final approval for a purchase or to secure project funding. It provides decision-makers with a clear, itemized breakdown of anticipated costs, aiding in accurate budgeting and financial planning.

While there is no universal legal standard, an effective pro forma invoice should be comprehensive and clear to avoid confusion. Key components include:
Several frequently asked questions highlight important distinctions.
Is a pro forma invoice legally binding? No. A pro forma invoice is not a legally binding request for payment. It is a preliminary document. The final sales invoice is the legally binding document that triggers the payment obligation.
Can I use a pro forma invoice to reclaim VAT? Generally, no. Tax authorities, such as HM Revenue & Customs (HMRC) in the UK, do not accept pro forma invoices as valid VAT invoices. You must issue a formal VAT invoice for tax reclaim purposes.
Do I still need to send a final invoice after a pro forma? Yes. Once the goods are delivered or the services are completed, you must issue a formal commercial or sales invoice to request payment. The pro forma invoice is replaced by this final document.
In summary, the most critical advice for using a pro forma invoice effectively is:
By integrating pro forma invoices into your financial workflows, you can enhance planning, reduce errors, and build stronger, more transparent relationships with clients and partners.
