VAT (Value Added Tax) is a tax that European companies have to charge when they sell products or services to clients in Europe.

When possible clients have to provide their VAT number to associate to the transactions about the products or services that they purchase from the European companies.

To avoid later problems it is important that the supplied VAT numbers are correct.

This class provides a solution to automatically validate VAT numbers, thus reducing the chances of any eventual problems.
