The ease of use; it's intuitive & easy for users who are not necessarily experienced or knowledgeable about payroll systems - plus there is an array available (e-tools) at multiple levels of complexity from entry level right up through advanced functionality.
There were many things I liked but perhaps most importantly was being able to easily set defaults when initially using the system rather than having every option customized per employee profile which can really slow down initial setup times. Having used Paychex before this implementation we wanted more features such as pay cycles / holiday schedules etc however they weren't provided within their product line making us look elsewhere like Acronis TrueTime HRMS instead where those additional functions exist. Overall good solution if you don’t need lots of bells n whistles – just make sure its compatible wth what you require otherwise may struggle getting full value benefit especially once training period.
