Proforma Invoice Template
A proforma is the invoice-shaped document you send before the sale is final \u2014 same line items, same layout, but explicitly not a demand for payment and not a tax document. Buyers use it to approve spend, open letters of credit, arrange import paperwork, or trigger a prepayment. This sheet keeps the proforma honestly labeled, with a validity date so old quotes expire on their own.
The quote, in invoice clothes.
Number it like the invoice it will become.
Give proformas their own series — PF-2026-012 — and when the sale lands, reference it on the real invoice: “per proforma PF-2026-012.” The pair gives everyone a clean thread from quotation to obligation, and keeps proformas from polluting your receivables numbering.
Convert deliberately: the moment goods ship or work starts, issue the standard invoice even if nothing changed but the label. Businesses that let the proforma stand in for the invoice end up with customers who treat every bill as negotiable — the document taught them that.
