EU VAT Lookup (VIES)

EU VAT Lookup adds a "Check VIES and fill" button next to the VAT number on the third party create and edit form.

How it works
1. Type an EU VAT number, for example SIXXXXXXXX.
2. Click the button. The number is checked on the official European Commission VIES service.
3. If it is valid, the company name, address, zip code, town and country are put in the form.

You stay in control
- Empty fields are filled in directly.
- Fields that already contain a different value are shown in a table (current value / value from VIES). Only the ones you tick are replaced.
- The module never saves anything. The form is only saved when you click the normal Save button.
- If another third party already has the same VAT number, a warning with a link is shown.
- If VIES is unavailable or does not answer, a clear message is shown and the form is left unchanged.

Features
- Uses the official VIES REST service. No account and no API key needed.
- Works on new and existing third parties.
- The single address line returned by VIES is split into street, zip and town. Always check the address before saving.
- Languages: English, Slovenian, French, Italian, German.

Important limits
VIES is a VAT validation service, not a company register. Some countries (for example Germany) confirm that the number is valid but do not publish the company name or address. In that case the module tells you so and leaves the fields empty. It never invents data.

Requirements
Dolibarr 24, PHP cURL extension, internet access from the server to ec.europa.eu.
