If you are sending any international shipments, you must attach a Commercial Invoice with your regular shipping label(s). This document is used for customs clearance at the destination country.
Some international carriers provide paperless customs documents, which remove the requirement for you to complete a Commercial Invoice. If you are not sure if your carrier offers this functionality, please get in touch with us or contact your carrier directly.
Shiptheory can automatically create Commercial Invoices on your behalf for eligible shipments. To enable, this functionality, please follow this guide here: How to set up Customs Documents in Shiptheory
