Commercial invoice example ### Getting Started Navigate to **Settings** > **Accounts** and select the account you want to configure. Scroll down to the **Customs Information** tab. Customs information tab in account settings You will find fields for entering your **EORI Numbers** and **IOSS Numbers**. Each includes a hyperlink with additional information about what these numbers are and how they are used. Open the individual **Product** record and go to the **Customs** section. Fill in the following required fields: Product customs details * **Country of Manufacture** -- The country where the product was made. * **Commodity Code** -- The tariff classification for the product. This code will appear as the **HS Code** on your commercial invoice. Entering this information ensures that all necessary customs data is included automatically when generating commercial invoices. ### Understanding EORI and IOSS Numbers Both EORI and IOSS numbers start with a two-character prefix identifying the country or region. This information is automatically added to commercial invoices when applicable. * **GB EORI Number** -- Used when shipping from a UK-based warehouse. Begins with "GB." * **NI EORI Number** -- Used when shipping from a Northern Ireland warehouse. Begins with "XI." * **EU EORI Number** -- Used for shipments from European warehouses. The prefix varies by country (e.g., "FR" for France). * **IOSS Number** -- Begins with "IM" and is displayed only when the total product value is **below EUR 150**. This is why adding the value to products is mandatory for commercial invoices and international shipping. ### Using the Feature in Shipments Once your details are configured, go to the **Shipments** menu. You will see a new **Commercial Invoice** column on the far right for any newly created shipments. Click it to download the commercial invoice. Commercial Invoice column in shipments If a shipment has already been completed, the **Commercial Invoice** column will remain visible but will no longer be interactive. ## International Shipments International shipments follow the same process as standard shipments, but a few mandatory details must be configured beforehand. ### Product Configuration Before you can ship products internationally, ensure each product includes: Product configuration for international shipping * **Value**: Added under the relevant product configuration tab (e.g., Unit, Case). * **Customs Details**: Under the **Customs** tab, complete these fields: * Commodity Code * Customs Description * Country of Manufacture Customs tab details If any of these fields are missing, the product cannot be shipped internationally. ### Warehouse Setup Make sure a **country** is selected in your warehouse settings.
