Frage: Hi when I try to checkout as a company, the VAT does not get discounted on the price, we are a Portuguese company
Antwort: the VAT does not get discounted on the price via "Reversed Charge Procedure" because you can get the included VAT back after the purchase when submitting your VAT return to your tax office. Unfortunately this is the only way our eCommerce shopping-system can handle it.
