Export Proforma Invoice Essentials

An export proforma invoice is a preliminary document that outlines the terms of sale before the goods are shipped. It is often used by exporters to obtain letters of credit, arrange financing, or secure customs clearance. While it shares many elements with a commercial invoice, there are specific additional items that must be included:

• Proforma Invoice Number and Date – Distinct from the commercial invoice.
• Estimated Shipping Date and Method – Air, sea, rail, etc.
• Packaging Details – Unit packaging, carton dimensions, and gross weight.
• Declared Value for Insurance – Often higher than commercial value.
• Letter of Credit Reference (if applicable).
• Export License Number – Required for controlled goods.
• Consignee and Notify Parties – Names and addresses for delivery and notification.
• Bank Details – For payment instructions.
• Terms of Payment – Usually more detailed due to financing.
• Signature of Authorized Exporter – Legally binding.
