The most useful feature I like about UltiMate are its integration capabilities with other systems such as Payroll or HRMS's and also it has many great features that you can use to improve productivity within an organization.
Also being able to view employee information from another system makes tracking employees much easier! There really isn't anything bad I dislike using Ultimate very well - some minor things that could be improved but overall good product!! We've been having issues finding software solutions specifically designed to address our specific business requirements (such as payroll processing). It seems there may not have ever existed any kind of solution available until now.
