When to send a proforma invoice
A proforma invoice is a priced offer written in the shape of an invoice. You send it before the sale is final. The buyer reads it and, if they agree, pays. Only then do you supply the goods or services and issue the real invoice.
HMRC, the UK tax authority, notes that these documents are often used to offer goods or services to potential customers. Offers usually do not last forever, so many sellers add a "valid until" date. That is a convention, not a rule.
What to include on a proforma invoice
No rule we found sets a fixed content list for an ordinary proforma invoice, so these fields are convention. Fill in the editor in this order:
- Proforma number. Use its own series, apart from your final invoice numbers.
- Issue date and, if you like, a valid-until date.
- Seller name and address.
- Buyer name and address.
- A ship-to address, if the goods go somewhere else.
- A reference or purchase order number.
- Currency, so the buyer knows which one you mean.
- Line items with a description, quantity and unit price. The amounts add up on their own.
- Tax and shipping, if you want to show an estimate.
- Terms, such as payment in advance, and payment instructions.
Leave out anything that does not apply.
Proforma invoice for international shipping and customs
In the United States, customs rules let an importer enter goods with a pro forma invoice when the commercial invoice is not available. That customs form asks for details such as the seller, the buyer, the consignee, a full description of the goods, prices and the country of origin.
This editor is not that form. Customs rules differ by country, so if a carrier or customs office asks for a specific format, follow theirs. The ship-to address and the description of each item in the editor are useful starting points.
How a proforma invoice differs from a commercial invoice and a quote
A quote states what you would charge. A proforma invoice does the same but looks like an invoice and invites payment. A commercial invoice, or final invoice, comes after the sale and records what was actually supplied.
In the UK, tax guidance says a proforma invoice should be clearly marked as one. It also says the buyer cannot use it as evidence to reclaim VAT. When you choose the UK in the editor, the line "This is not a VAT invoice" is printed for you. Showing tax on a proforma does not turn it into a VAT invoice.
Turning a proforma invoice into a final invoice
Once the buyer pays or you supply the goods, a normal invoice follows. For a UK VAT-registered seller, HMRC says a full VAT invoice must then be issued, and that sending a proforma does not change the tax point, which follows the normal rules.
Keep the proforma number out of your invoice series. When you are ready, use our Invoice tool to create the final invoice, and our Receipt tool to confirm payment.

Questions
What is a proforma invoice used for?
It is used to offer goods or services at a stated price and invite payment before they are supplied.
What is the difference between a proforma invoice and a commercial invoice?
A proforma invoice is an offer sent before the sale is complete. A commercial invoice is issued once goods are supplied and records the actual sale.
Is a proforma invoice the same as a quotation?
Not exactly, but they are close. Both state prices before a sale. A proforma invoice is laid out like an invoice and invites payment, so it can later be followed by a final invoice.
Do I need a proforma invoice for shipping with FedEx?
Not necessarily. We found no source that says a proforma invoice is always required for a shipment. The one case we checked is US customs, which can accept a pro forma invoice when the commercial invoice is missing. Ask your carrier and the destination country what they need.
Is a proforma invoice a legal request for payment?
No, as far as our sources show. It invites payment, but it is not a tax invoice or a record of a completed sale, and we found no source saying it is a binding demand. In the UK, tax authorities say it is not a VAT invoice and the buyer cannot use it to reclaim VAT.
Can I make a proforma invoice in Word or Excel?
Yes, but you build the layout and the totals yourself. The editor above adds up the amounts for you and exports a PDF.
