This is a very well designed set of tools to extend your practice management systems power. The tools will give you and your staff all kinds of information and even more importantly it will track how you are doing and it will do it automatically.
However in order to use this or any other of the great tools you must have complete, accurate and up to date digital information. Tools like PLZ are just another great benefit of going paperless. Once your data (chart, schedule, finances etc) is digital it changes everything!
