I like that it allows you can send messages back & forth at any time of night or during work hours without interruption from others who are not directly involved with projects such as myself - this helps me stay focused while working late into nights if needed! Not much dislike about prontosoftware but sometimes their servers seem slow so i have had some issues logging onto my account when trying to do updates etc.. But overall its been great using them through out our business career here within E&Y.
