VAT rules, how does it work exactly?
We have standardized the standard requirements of the EU on taxes in our system.

There are two scenarios where the VAT is automatically shifted to 0%:

1. When a company within or outside the EU with a valid VAT number places an order in your webshop.
2. When consumers outside the EU place an order (including Norway and Switzerland)

Please note that this only applies to countries to which the product is sent, so the 'shipping' country must be outside the EU or within the EU with a valid VAT number.
