The ability for me as an owner of clinic ware was being able see all my patients in one place instead having several different spreadsheets or apps open at once! It has been very helpful with keeping up date information about our clients health records which makes it easy when we have questions regarding their care during visits etc..
I am not sure if there are any downsides but so far no issues whatsover!! As always its best just try out anything new because sometimes things don't work like they should right away.
