We are currently using it for are HRIS in our HR department. It is used for payroll as well. We have rolled out self-service to a few of our employees. It helps bring all functions of the HR/Payroll together in one system.
Overall to me, it has not been the best transition. The startup was rushed and not everything was set up properly. We continue to have issues, that make "us" as a department look bad. This is partly our fault and part the
implementation set up. The system is great as an HRIS, but when it comes to payroll/taxes not so much.
