Monta ApS is based in Denmark. For customers without a valid VAT number in their account, Monta therefore charges the Danish VAT rate of 25%. So it is not a Belgian rate, but it is correct.
Are you a VAT-registered company? Then enter your VAT number in your account settings (Settings > General information). Reverse charge then applies and the invoice shows 0% VAT.
If you are not VAT-registered, do not enter a VAT number and do not enter your company number as a VAT number. There is a separate field for that.
Has an invoice already been sent with 25% VAT? Create a ticket via the helpdesk. A correction goes through Monta's finance team and is not guaranteed.
