PEO Services

At ONYX, we help growing companies slash overhead, reduce risk, and elevate their employee experience — all without adding more to your plate.


We match you with the right PEO, not just any one — and that means access to Fortune 500-level benefits, robust HR tech like iSolved, full compliance support, and strategic risk management — all under one roof.


For example, in 2025 we helped a company unlock over $575,000 in annual savings, while improving their plans and offloading the HR burden completely.


You stay focused on growth. We handle the heavy lifting
