Hello everyone,

I’ve added automatic vendor validation with an option to show or hide it on the vendor registration page.

The update also relies additionaly on the default multivendor tax field handling and works flawlessly with all regular CS-Cart versions.

Additional features include:

  • Manual validation and cleanup options
  • A control modal to verify numbers against registered companies
  • Full frontend and backend support
  • Automatic creation of the CS-Cart tax field (if missing) to pass VAT data to customer order details
  • Display of tax exemption status in the order section
  • Manual VAT number testing directly from the add-on page
  • New filtering logic on the view add-on page for easier data handling

Hello VAT VIES Add-on Owners,

Great news! The add-on has been extended with a new feature to fully align with EU VAT regulations.

The system now correctly implements EU VAT law:

Domestic B2B sales remain taxable

Only cross-border B2B transactions are zero-rated

New Option: Disable Tax Exemption in Your Operating Country

You can now select the country where your business is established.

If a customer or vendor provides a valid VAT number from your selected operating country, automatic tax exemption will NOT be applied. Domestic B2B transactions will remain taxed in accordance with EU VAT rules.

Leaving this field empty will apply tax exemption to all eligible EU countries.

How VAT Must Be Configured in CS-Cart

To ensure the VIES VAT Validation Add-On works correctly, taxes must be configured normally in CS-Cart. Tax rates should exist for all countries where you are VAT registered.

Do not set EU countries to 0% VAT and do not remove tax rates.

The add-on works by removing VAT from validated B2B customers during checkout. For this process to work, a tax rate must exist first. If a country already has a 0% tax rate configured, there is no VAT to remove, and it may appear that the exemption is working when in reality no tax adjustment was made.

Single-Storefront Example

For a German business selling across the EU:

Set Operation Country to Germany (DE) in the add-on settings.
Configure your VAT taxes normally in CS-Cart.
German customers with a valid VAT number remain taxable according to domestic VAT rules.
Customers from other EU countries with a valid VAT number qualify for intra-community VAT exemption and VAT is automatically removed at checkout.
Multi-Storefront Example

If you operate multiple storefronts, such as Germany and Latvia:

German Storefront

Operation Country: DE
German customers pay VAT.
Validated B2B customers from other EU countries receive VAT exemption.

Latvian Storefront

Operation Country: LV
Latvian customers pay VAT.
Validated B2B customers from other EU countries receive VAT exemption.

The add-on evaluates VAT rules separately for each storefront and automatically applies the correct taxation logic based on the storefront’s configured operation country.

Important

Always configure your tax rates as required by your business and local tax regulations. The VIES add-on does not replace tax configuration—it simply automates VAT exemption for eligible and validated EU business customers.
