A pro forma invoice is a preliminary bill sent before a sale is finalised. It shows the buyer exactly what the goods or services will cost - so they can approve the purchase, pay a deposit, arrange finance, or clear customs - but it is not a demand for payment and it is not a tax invoice. When the order is confirmed you replace it with a real invoice.
When a pro forma invoice is used
- To quote a committed price the buyer can raise a purchase order against
- To request a deposit or advance payment before work or shipping begins
- For international shipments - customs and freight forwarders use it to value goods for import
- So a buyer’s finance team can set up the supplier and approve the spend
Pro forma invoice vs invoice vs quote
A quote is an offer of a price. A pro forma invoice looks like the final invoice - same layout, line items and totals - but is explicitly marked “pro forma” so it is clear that no tax point has been created and no payment is yet legally due. A true (tax) invoice is the one that triggers VAT/GST accounting and the obligation to pay. This tool prints the “not a tax invoice” wording for you and lets you convert it to a real invoice with one click.
