Now because of the incompatibility of QuickImmobilie 2005 Win7 / Win8 the update was on QuickImmobilie 2015 Start performed. This is not really an update but a completely new product. Due to the length of time significant changes are traceable. However incomprehensible is the less intuitive and user-friendly user interface. Much worse, however, is the fact that functionalities are obviously fallen over the years to the "rationalization devil" victim. Administrative expenses for master data and bookings has become immensely without any added value compared to stands. Reports and lists are reduced to a minimum or unusable or non-existent. A traceability of reckoning is almost impossible. I look with horror at the first final bill (if I do not advance in the towel throw).
