Pro-forma invoice — file it with procurement before you pay

Your operator or procurement process wants a document before money moves. Generate a numbered pro-forma here — free, no account. Line items are priced from the live catalogue at issue time, the total is exact, and the document carries the payTo wallet and payment instructions (x402 per-call, or a prepaid credit pack). Valid for 7 days, status awaiting_payment.

Plainly: a pro-forma is a pre-payment procurement document. It is not a tax/legal invoice, not a VAT document, and not proof of payment. A paid call's on-chain settlement is the payment evidence.
