$577K in annual savings, with zero disruption.
A 500+ employee national mortgage lender was overpaying on benefits and absorbing rising premiums with no visibility into savings. ONYX shopped the top national PEOs, redesigned plan options, and managed a zero-disruption transition of 100+ employees, recovering $577,000 in annual savings plus up to $175,000 more from employee buy-down plans.

“ONYX found us a better PEO and saved us 13% on health insurance alone, without disrupting a single employee.”
“The side-by-side comparison was the first time we actually understood what we were paying for. No sales pressure, just numbers.”
“Our transition was seamless. ONYX handled the compliance and onboarding so my team could keep doing their jobs.”
The short version
A PEO (Professional Employer Organization) co-employs your workforce so you can offer large-group benefits, run payroll, and stay compliant without building a full HR department. You keep day-to-day control of your people; the PEO handles benefits, payroll, workers' comp, and HR compliance through a co-employment relationship.
An independent PEO broker shops multiple PEOs on your behalf, compares them line by line, and recommends the best fit, instead of selling you one provider. ONYX is paid the same regardless of which PEO you choose, so the recommendation reflects your interests, not a sales quota.
The audit and comparison are free. ONYX is compensated by the PEO you select, the same model as an insurance broker, so your pricing is not marked up for using us. If you decide not to switch, you owe nothing.
Going direct gets you one quote from one salesperson. ONYX runs your requirements across the top PEOs, negotiates because they know they're competing, and gives you transparent, line-by-line pricing. Most clients save 15–40% on total people cost versus their starting point.
Typically 3–5 business days from receiving your census and current rates to a side-by-side comparison of your best PEO options.
