形式发票PDF — 使用方法
A proforma invoice is a preliminary bill you send before the final tax invoice. It shows expected line items, prices, and terms so the buyer can approve scope or arrange payment — without treating it as the final accounting document.
Use a proforma when you need a formal quote-style PDF for customs, advance payment, or client approval. When work is complete, issue a final invoice (or GST invoice) with the same totals where appropriate.
Billvale’s free proforma generator mirrors a professional invoice layout so buyers recognize the document, while you keep control of numbering and notes that mark it as provisional.
Who it's for
- Exporters who need a provisional value document before shipping
- Freelancers collecting deposits before starting work
- Agencies that send a formal preview of fees for client sign-off
How to use this tool
- Label the document clearly as a proforma invoice in the title or notes.
- Add seller and buyer details plus provisional line items.
- Include currency, tax estimate if relevant, and payment or deposit instructions.
- Download the PDF and share it for approval or advance payment.
- Later, create a final invoice when goods or services are delivered.
Field guide
What to include
- Seller and buyer names and addresses
- Provisional line items with quantities and rates
- Currency, estimated tax, and validity or deposit notes
Mistakes to avoid
- Using a proforma as if it were a final tax invoice for your books
- Omitting “proforma” language so the buyer confuses it with a final bill
- Changing prices later without issuing an updated proforma or quote
