Guest cards, guest contribution accounting and registration forms have arrived in the present: Modern, online-based technologies and smartphone solutions  from AVS have made check-in processes and the accounting of tourist taxes significantly easier through an interface-capable platform with many additional functions. Larger accommodation providers can report via their PMS, while smaller companies have a user-friendly internet form at their disposal. The billing of guest contributions can also take place completely digitally via a billing portal and your accommodation providers can also report to the State Office for Statistics from the AVS system.
