Can I reclaim VAT on a proforma invoice?

No. A proforma invoice is not a valid VAT invoice, so the VAT shown on it cannot be reclaimed. Ask the supplier for a proper VAT invoice once you have paid or received the goods, and reclaim the VAT on that document.

Is a proforma invoice legally binding?

Not usually. It is a detailed quote or request for payment, and the buyer can choose not to proceed. The binding contract is formed when the order is accepted, and the debt is recorded when the final invoice is issued.

What is a proforma invoice?

A proforma invoice is a preliminary bill sent before goods or services are supplied, setting out what will be charged; it is not a demand for payment for VAT purposes.

What a proforma invoice means

A proforma invoice looks like a normal invoice, with the seller's details, a description of the goods or services, quantities, prices and the total, but it is sent in advance. It tells the buyer exactly what they will be charged so they can arrange payment, approve a purchase order or clear goods through customs.

It is common when a supplier wants payment up front from a new customer, when a customer's finance team needs a document to release funds, and in international trade, where customs authorities use it to value a shipment before the final invoice exists.

Proforma invoices and VAT

For UK VAT, a proforma is not a valid VAT invoice. It should be clearly marked "This is not a VAT invoice". The buyer cannot reclaim VAT on it, and the seller does not account for output VAT when it is issued. Once payment is received or the goods are supplied, whichever is first, a proper VAT invoice is issued and VAT is accounted for at that point.

This matters because issuing a full VAT invoice early would create a tax point and make the seller liable to pay VAT to HMRC before the customer has paid.

Example

A furniture maker agrees to build a £4,000 dining table for a new restaurant client and asks for full payment before starting. It sends a proforma for £4,000 plus £800 VAT, total £4,800, marked "not a VAT invoice".

The client pays £4,800 on 3 March. The maker then issues a VAT invoice dated 3 March and includes the £800 output VAT in that quarter's return. The restaurant reclaims the £800 using the VAT invoice, not the proforma.

Why it matters for your business

Proformas let you take payment before committing materials or time, which protects cash flow and reduces the risk of bad debts with unfamiliar customers. Because they do not count as sales in your books, they keep your revenue, accounts receivable and VAT returns accurate. Most accounting software can produce a proforma as a "quote" or "estimate" and convert it into an invoice when paid.

Proforma vs invoice

A proforma is a request or a statement of intent with no legal obligation to pay; the buyer can still decline. An invoice records a completed sale and creates a debt. Only the invoice goes into your sales ledger and your VAT return.
