- The Automation Difference
Why Our Quoting Engine Changes The Game

Digital Intake
Secure upload of census, current plans, and payroll data. Our team helps you gather only what is essential.

Automated Benchmarking
The platform evaluates cost, risk class, industry, geography, and salary mix, then aligns you with the PEOs most likely to deliver the right blend of price, coverage, and technology.

- Why “High‑Caliber” PEOs Only
We Are Selective On Purpose
Not every PEO can serve organizations with complex needs and real risk profiles. Onyx works only with a short list of providers that:
- Maintain strong client retention
- Invest in modern technology and integrations
- Offer real service teams, not ticket queues
- Have proven stability in renewals and claims handling
If a PEO cannot meet these standards, they do not appear in your comparison.
Is Onyx A Fit For You
You are in the right place if:
- You are juggling multiple vendors for payroll, benefits, and workers compensation
- You want clearer data, not more noise
Why Choose Onyx for Your PEO Needs
Businesses often overpay on payroll, benefits, and workers’ compensation without realizing it. Onyx conducts thorough cost audits and compares multiple PEO options so you can uncover hidden savings while maintaining or improving coverage quality.
