Unfortunately, it is not possible for us to fill in and sign your checklist for cash management, both factually and legally. Simply because we are not involved in all of your operations.
We have compiled and answered all information which is normally requested in such checklists, as far as this is possible as a manufacturer of a POS system. For further information, please refer to our detailed descriptions and information sheets on data security, GdpdU/GuB and the Austrian E131 regulations (on the internet or on our homepage).

This is far more detailed and accurate than most POS providers!
Please contact your tax advisor for more detailed information.
