VAT numbers verification (VIES)

VAT Information Exchange System - abbreviated VIES - is a tool provided by the European Commission that allows you to check the validity of VAT numbers of companies registered in the European Union.

CoquiAPPs provides a feature to Verify VAT Numbers when you save a contact. This helps you make sure that your contacts provided you with a valid VAT number without leaving CoquiAPPs interface.


To enable this feature, go to Accounting ‣ Configuration ‣ Settings ‣ Taxes, enable the Verify VAT Numbers feature, and click on Save.

Whenever you create or modify a contact, make sure to fill out the Country and VAT fields.
