I can say that it's very easy of use if you have any knowledge in ERP or CRM system like this one from B1C! You don't need more then 10 min for install/set up your first user account inside an organization where there isn´t anything similar already installed as well how many modules would fit? It fits every needs perfectly because its so simple but powerful at same time too!! The only thing i dislike about bacisio business 1 c are some options which could be improved regarding look&feel since they're still not 100% perfect after 7 years ago when we were using them before moving towards newer versions now available out today in marketplaces such us; Amazon Web Services App Store etc.. Also sometimes during heavy load period performance drops down slightly though nothing major just minor lags here & again no big deal really considering overall benefits provided by service offered compared w others currently used nowadays even better.
