Commercial Invoices and International Shipping

We’re excited to announce the release of our new Commercial Invoice & International Shipping features, designed to give you greater control and visibility over your shipments.

Here is an example of how the commercial invoice looks

Getting Started

Understanding EORI and IOSS Numbers

Both EORI and IOSS numbers start with a two-character prefix that identifies the country or region of origin. This information is automatically added to your commercial invoices whenever applicable.

  • GB EORI Number – Used when shipping from a UK-based warehouse. These numbers begin with “GB.”

  • NI EORI Number – Used when shipping from a Northern Ireland warehouse. These begin with “XI.”

  • EU EORI Number – Used for shipments from European warehouses. The prefix varies by country (for example, “FR” for France).

  • IOSS Number – Begins with “IM” and is displayed only when the total product value on the commercial invoice is below €150. This is why adding the value onto the products is mandatory for the commercial invoice, and international shipping.

Using the Feature in Shipments

Once your details are correctly configured, head to the Shipments menu. You’ll now see a new column on the far right labelled Commercial Invoice for any newly created shipments. From here, you can easily download the commercial invoice.


Please note: if a shipment has already been completed, the Commercial Invoice column will remain visible but will no longer be interactive.

International Shipments

International shipments in Clarus follow the same process as standard shipments, but there are a few mandatory details that must be configured beforehand.

Product Configuration

Before you can ship products internationally, ensure each product includes the following information:


  • Value: Added under the relevant product configuration tab (e.g., Unit, Case, etc.).

  • Customs Details: Under the “Customs” tab, complete the following fields:

    • Commodity Code

    • Customs Description

    • Country of Manufacture

Note: 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. This is essential because the system automatically uses the correct EORI number based on the warehouse’s assigned country.


Completing the Shipment

Once your products and warehouse are properly configured, you can:

  • Select your carrier and carrier service for international shipping.

  • Proceed to complete your shipments as usual.
