An invoice that is created on paper for exported goods to provide the customs authorities with evidence of the cost of the goods.
When you deal in export, you may need to print pro forma invoices. They are used to give the importer or the responsible authorities in the import country details about forthcoming shipments.
A pro forma invoice appears exactly the same as a customer invoice. The difference is that this invoice does not need to be paid. Therefore, the system does not forward data to Financial Accounting (FI). No statistical data is created on the basis of pro forma invoices.
