Validate before buying
Pricing is not published and quotes are custom; reviewers cite cost and transparency, a five-employee minimum, and limited customization.
Pricing is quote-only, worksite-employee counts declined year over year in FY2025, and the co-employment model may not suit buyers wanting to retain full employer control (mitigated by HR Plus).
