I like that it has all my client's data, so if they are not using their own system anymore or need to update something from years ago - we can do this easily with our clients' information! It is easy for me as well since everything stays organized within one platform instead having multiple systems (which could be confusing).
There isn't anything really bad about druondosoft at least yet but i am sure there will come along time when someone gets frustrated because its hard/confusing etc.. We use Druidsoft mainly just due too ease & organization purposes only though sometimes you might have issues finding what your lookingfor which may take some searching around online maybe? But overall very happy customer!! Keeping up wtith new changes / updates without any problems :).
