I'm a big fan of Zenefits.<p>At my last startup, we grew from 0 to 65 employees without the help of Zenefits and it was painful. Employee on-boarding, HR paperwork, and healthcare enrollment were all done manually.<p>Now, Zenefits can handle all that for us. We could send new hires the paperwork they need to fill out before they even start. This makes onboarding so much easier.<p>(Note, I'm not affiliated with Zenefits. Just a big fan.)
