The best thing about this software is its simplicity, it's easy to use for all users from managers up until employees themselves! It has many features that can be used in different ways depending of your needs or requirements as well how much information you have at hand when using such programs/apps like staffomatic (I'm talking mainly here only).
I would say there are not too specific things i dislike but mostly some minor bugs which could easily get solved with an update if they were really important issues - don't hesitate though because these little problems will definitely disappear after updating them! You should check out their free trial version before buying any license since sometimes companies want proof first what kind off benefits one gets by purchasing certain licenses / solutions etc.. This app helps me manage my shifts very efficiently so far without losing time managing paper files nor having difficulties keeping track where people work during day times especially now we started.
