We have been using the software for 15 years and have had very good experience. It is a consistent system of material, items, offer, project management, cost control, hours, document management, appointments, etc.. One is flexibly positioned here and gets in all areas the necessary information that one needs to decide the next steps and that in the shortest time. The programmers also respond to customer requests if it is possible and fits into the philosophy. The depth in the individual areas of the program e.g. in the formatting of texts etc. is more extensive in special programs. All in all, it has been a real benefit for us and has helped us to make lasting progress. The price/performance ratio is top.
