Notes
A proforma invoice is used to open an L/C or arrange a transfer and to clear customs on both sides — HS codes and the country of origin should match the commercial invoice you will issue against the same shipment.
The proforma comes after the quotation is accepted and before the shipment — the packing list and the purchase order complete the flow.
