For large companies, you're competing with peoplesoft. Peoplesofts UI is shit, in my opinion, but then I'm only the guy trying to book his holiday with it, rather than the HR people who bought it. What it offers them is an integrated solution. I assume it plugs into payroll etc. It also does expenses, yearly appraisal, yadda yadda. I don't know how you're going to compete with that.
