Pro Forma Invoice
A pro forma invoice is a preliminary document in invoice format that describes a proposed sale before the final commercial or tax invoice is issued.
A seller may use a pro forma invoice to confirm expected items, prices, delivery terms and payment arrangements. It looks like an invoice, but it should be clearly labelled so the buyer does not mistake it for the final accounting or tax document.
The U.S. International Trade Administration describes a pro forma invoice as a quote in invoice format and notes its use in export arrangements such as import licences and letters of credit.
Where Pro Forma Invoices Appear
You may see pro forma invoices in:
- international trade and customs preparation
- advance-payment or deposit requests
- first transactions with a new customer
- order confirmation before goods are produced or shipped
- internal purchasing approvals
- buyer finance or foreign-currency arrangements
They are less common in routine local sales where a normal quote, sales order and final invoice provide enough information.
Pro Forma Invoice Versus Quote And Invoice
| Document | Main Purpose | Accounting Treatment |
|---|---|---|
| Quote | Offers a price and terms for proposed work or goods | Normally not posted as a sale |
| Pro Forma Invoice | Presents a proposed sale in detailed invoice form | Normally kept as a preliminary document, not the final sale invoice |
| Commercial Invoice | Records the final trade transaction and shipment details | Used in the final sales and trade records |
| Tax Invoice | Provides the information required by the relevant GST or VAT rules | Supports tax reporting and, where allowed, input tax claims |
The title of a document does not by itself decide whether a binding agreement exists. Accepted terms, conduct and local contract law may matter. Businesses should make validity periods, payment terms, delivery assumptions and the preliminary status clear.
What To Include
A practical pro forma invoice often contains:
- seller and buyer details
- a unique pro forma reference and issue date
- a clear “Pro Forma Invoice” label
- descriptions, quantities and estimated prices
- currency, freight, insurance and other charges
- proposed tax treatment
- delivery terms, including Incoterms where relevant
- payment terms and bank details where advance payment is requested
- expected shipping date and validity period
- a statement that it is not the final tax invoice
Export requirements vary by destination and product. The importer, customs broker or freight forwarder should confirm which documents and values are required.
Simple Example
An Australian equipment supplier receives an overseas order for ten parts. Before production, it sends a pro forma invoice showing the part numbers, quantity, unit prices, freight estimate, currency, Incoterm, expected shipping date and 30-day validity.
The buyer uses the document to arrange approval and payment. When the goods are supplied, the seller issues the final commercial invoice and any tax documentation required for the actual transaction.
Pro Forma Invoices And Australian GST
A preliminary document should not be treated as a valid Australian tax invoice merely because it resembles one or includes an estimated GST amount. The ATO explains that a tax invoice is a document issued for a sale that shows required supplier, price and GST information.
If payment is received in advance or the supply occurs, the seller should review the GST timing and issue the appropriate final document. Buyers should not claim an input tax credit from a document that does not meet the applicable tax-invoice requirements.
Why Pro Forma Invoices Matter
Pro forma invoices reduce ambiguity before a complex sale. They give buyers, sellers, banks and logistics providers a common description of the expected transaction.
Their preliminary nature is also the main risk. If the final quantity, price, freight, currency or tax treatment changes, the commercial invoice and accounting records must use the actual transaction rather than an outdated estimate.
Common Pro Forma Invoice Mistakes
- failing to label the document clearly as pro forma
- giving it the same status or number sequence as final invoices without controls
- posting the proposed amount as revenue before the accounting criteria are met
- claiming GST or VAT from a document that is not a valid tax invoice
- omitting currency, validity, freight or delivery terms
- using estimated data for customs without verifying the final commercial information
How Gimbla Can Help
Gimbla’s quote and invoicing records can keep the proposed sale separate from the final customer invoice. Once the terms and actual supply are confirmed, the final invoice should use the approved customer, item, price and tax details rather than creating a duplicate sale.
Clear numbering and status labels help staff distinguish quotes, pro forma documents and posted invoices during review.
