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
