The booking is completely handled by XING Events, a highly secured German event service. You will receive an invoice with German VAT directly after your booking per mail sent by XING Events. If you book the workshop day, you can specify the desired workshop track in the ticket booking. A later change to another track is possible on request, as long as the tracks are not fully booked.
ATTENTION: You can already purchase tickets for the 4th BA-DAY on 23 March 2023 here, although the programme has not yet been published!
