Optimum Payroll (iSeries) is not intuitive or user friendly. We are looking at other products currently because we have been dissatisfied with reporting functionality. We've had to build our own reporting process because of the inflexibility of Optimum.
We also seem to have issues that need to be fixed occasionally when we do upgrades.
The applicant tracking does not meet our needs.
We have used Optimum Solutions for our Applicant Tracking, HR management, Payroll and Time & Attendance.
