Number Name Description
1 Electronic Certificate of Origin (eCO) Businesses issuing international invoices must attach an Electronic Certificate of Origin (eCO) as proof of the product's country of origin, which facilitates customs clearance and compliance with trade agreements. The eCO is a digitally authenticated document issued by authorized chambers of commerce, streamlining export processes and minimizing delays at border inspections.

This report verifies transaction authenticity, supports customs clearance, and facilitates seamless cross-border trade by providing audit trails and compliance evidence.
8 Foreign Exchange Control Certificate When issuing an international invoice, businesses must attach a Foreign Exchange Control Certificate to comply with regulatory requirements governing currency transactions and cross-border payments. This document verifies authorization for foreign exchange operations, prevents currency misuse, and ensures transparency in international trade settlements.

This document helps customs authorities assess export restrictions and verify that the shipment adheres to legal requirements, preventing export violations and potential penalties.

These digital contracts provide immutable proof of agreement, facilitating seamless cross-border payments and reducing disputes in global trade documentation.
