FAQ

A proforma invoice is a preliminary document sent before the final invoice. It details the goods or services to be supplied with estimated prices. It is not a legally binding payment request — it is a commercial commitment used to get buyer approval before work begins or goods are shipped.
A VAT invoice is a legal document that creates a payment obligation and lets the buyer reclaim VAT. A proforma invoice is a draft — it communicates price but is not a valid tax document and cannot be used for VAT reclaims. Once the client approves, issue a proper VAT invoice.
Use a proforma: (1) before confirming an order for client price approval; (2) for import/export — UK customs may require it to assess duties; (3) when the client needs internal purchase-order approval before paying; (4) as a formal quote before starting work.
A proforma invoice has no VAT or accounting validity in the UK. HMRC does not recognise it as a tax point document. It cannot be used for VAT reclaims. It may carry contractual weight as a commercial offer if agreed in writing between parties.
