Free Proforma Invoice Generator
A proforma invoice tells your buyer exactly what to expect before the sale is final — common in exports, advance payments, and B2B approvals. BillFast lets you build one in a minute: label it clearly, itemize the goods or services, and send.
Type 'PROFORMA' into the invoice number prefix (e.g. PF-001) and state the terms in the notes field — then issue the final invoice by duplicating it when the deal closes.

Frequently asked questions
Is a proforma invoice legally binding?
No — it's a preliminary document for approval, customs, or advance payment. The final tax invoice follows the actual sale.
How do I mark it as proforma?
Use a PF- number prefix and state 'Proforma — not a tax invoice' in the notes. Both print clearly on the document.
Can I use it for export shipments?
Proformas are standard in international trade for customs pre-clearance and buyer approval — include quantities, values, and currency.
How do I issue the final invoice later?
History → Duplicate, adjust the number, done.
