If you have already ordered and paid for KNX products/services, but you have forgotten to enter your VAT number, and you are eligible for VAT exemption, then there is a possibility to have a refund of the VAT difference.
There is however an administrative fee of a minimum of 50€ that will be charged for correction of the bill, issuing of a credit note, and refund of the paid VAT. If you wish to be refunded, please contact us.
