Configuration > Business Data > VAT Numbers
What does it mean?
VAT Numbers are mandatory. In case you are no subject to tax, please at least save a placeholder. A VAT number is defined by a combination of a country and a business unit. For example a company has two branches, a bus and a boat branch. BUS and BOAT are the Business units and they are active in the Netherlands. Therefore a VAT number needs to be registered for each business unit/country combination, even though it might be the same number.
What should I do?
Register for each combination of business unit and country the corresponding VAT number. Please make sure that the number is entered correctly, as it will be printed on the ticket accordingly (if selected).
