Our Verdict — Best Of The Best

Price: Custom

OrangeHRM is a comprehensive, user-friendly HR management solution for businesses seeking open-source software. We think it’s the best because of its robust employee management tools, efficient attendance tracking tool, and easy-to-use recruitment features.

The Best Part:

  • Next-level reporting and analytics. OrangeHRM's customizable reports and graphical visualizations make it a breeze to assess your organization's HR performance, and to get insights on how to improve said performance.
