Invoicing glossary
Proforma invoice
A proforma invoice is a preliminary bill of sale sent before work or delivery, showing the expected cost — it is not a demand for payment.
Proforma invoice: a clear definition
Clients use a proforma invoice to approve a purchase, arrange financing, or handle customs. It looks like a normal invoice but is clearly marked “proforma” and doesn't count as a tax invoice or a record of a completed sale. Once the work is delivered, you issue a final invoice.
