It serves those in the European Union involved with invoicing intra-EU transactions, and those in need of a handy and speedy VAT calculator that works in all EU states. How does it work? As the user types a VAT number of any EU state, the app examines its correctness ("well-formedness") on-the-fly using the actual algorithms of each EU state, not just the number and type of digits! This step ensures usability and keeps traffic and fees low. EU VAT numbers (from any of the 28 EU states) are checked using the official web service maintained by the European Commission's VAT Information Exchange System (VIES). Attention: Not all correct VAT numbers are valid, therefore you must always check the validity of all VAT numbers before actually using them in invoices.
