This module extends base_vat module features allowing to know if VIES
validation was passed or not.

Then you can use "VIES validation passed" field in order to show VAT ID with
or without country preffix in invoices, for instance.

*NOTE*: Although VIES validation is set in your company, this validation
will not block VAT ID write (main difference to Odoo standard behavior) if this
VAT ID is valid in its country.

Configuration
=============

In order to activate VIES validation, you must set this option in Settings:
Settings > Account > Verify VAT Numbers

Usage
=====

When VIES VAT Check is activated:

* Odoo will try to validate VAT against VIES online service
* If passed, then "VIES validation passed" field will be True
* If not passed, then try to validate using country validation method
* If validated, then "VIES validation passed" field will be False
* If not validated, then a ValidationError will be shown to user

When VIES VAT Check is not activated:

* "VIES validation passed" field will be always False

You must prefix VAT with country code (ISO 3166-1 alpha-2) and if you want to
bypass country validation you can use "EU" code
