Upload is not possible without stating the price excl. VAT

Does your own vAT number and the vAT number of the Dutch company appear on the invoice? In that case, there is a vAT reverse charge and the amount incl. vAT is the same as the amount excl. vAT. You must then submit a special vAT declaration 629 to the vAT authorities once a quarter and pay the vAT on the amount to the Belgian vAT authorities.
