Anshul, I am giving you a link to a simple article which explains well about what is AMS and how it is useful, etc. Please click Apartment management software and its significance .. You will get clear idea about AMS once you read this.
All the services, equipments, facilities, ect provided in your apartment can be monitored using Apartment management software.. All apartment owners will be members in it and the main person (secretary or president of your apartment) will be given the moderator access. Monthly maintenance bill can be generated through AMS and residents can check their bills and pay it from their homes itself.. Like this there are many ways in which AMS can be used..
