Yes, you can! But how?
The main legal point of your future cooperation with Xometry Europe is to be able to issue official invoices for performed orders.
So, you need to register yourself as an individual entrepreneur or as a small business. In this case on your invoices should be the following text: “The supplier is not VAT payer” or “Small business – VAT not applicable”. The net sum will be equal to the gross sum (VAT 0%).
