When does reverse charge be applied?

billwerk will use automatically reverse charge, if three preconditions are valid:

1. A valid VAT ID has to be saved at "Settings > Account > Company".
2. The customer saved a valid VAT ID in his customer details.
3. The customers company is not in the same country as your company, but it's inside the European Union.

If all of them is correct, billwerk will automatically use reverse charge and will display this on the invoice with a specific text. 

If the country of the VAT ID number differs from the country of the invoice address, the country of the VAT ID number is used for invoice generation and taxation.
