Proforma invoice vs Invoice

What is proforma invoice?

A proforma invoice looks like an invoice but is clearly marked “proforma”. It's used to confirm a purchase, arrange financing, or clear customs before goods or services are delivered. It isn't a tax invoice and doesn't record a completed sale.

What is invoice?

A final invoice is the real request for payment, issued once the work or goods are delivered. It has a unique invoice number, counts for tax, and is what the client actually pays.

Proforma invoice vs Invoice: the key differences

Here's how proforma invoice and invoice differ at a glance:

• Stage — proforma before delivery; final invoice after.
• Legal weight — proforma isn't a tax document; the final invoice is.
• Numbering — only the final invoice carries an official invoice number.
