Bert, Appreciate the feedback. When someone pays their fee we send a Purchase Confirmation. That confirmation states: This is not a VAT invoice. A final VAT invoice will be sent with all the required VAT information within 45 days. Instructions will be included on the process to follow to recover the VAT paid by qualified attendees or their employers. The invoice for your participation will be issued by VMC, 14-30 rue de Mantes, 92700 Colombes / France, French VAT Number: FR75523098614; Czech VAT Number: CZ682761770. Perhaps notice to the list would have been helpful.
