It is very easy to use, it has great customer service for any questions you have or issues that arise during your trial period with them as well! I am not really sure what i do like best about simpler but they seem pretty organized which makes sense because of their business model being so simple (no contracts).
There's nothing bad at all we've experienced in our experience when using this software either positive nor negative just overall good stuff :) We were looking into different ways how companies could keep track/manage employees while also keeping up-to date wih payroll information without having multiple systems running simultaneously - This did exactly solve those problems by allowing us access from anywhere via mobile devices even if out off site!!
