A PEO lets geothermal installers run payroll, offer Fortune-500–level health benefits, and stay compliant across every state they operate in — through a co-employment model that gives a small employer enterprise-grade HR economics. It also pools your workers' compensation at the PEO's blended experience-mod rate, often the single biggest cost lever for geothermal installers. Below: what a PEO does for geothermal installers, the real cost structure, and how to compare providers.
PEO blended pool mod replaces your individual mod — most industries see 20–45% premium savings, often the single largest line-item value in a PEO transition.
Group health at large-employer pricing through Aetna, BCBS, UHC, Cigna — typically 15–32% below what a 10–60 EE operation can negotiate solo.
CPEO-certified PEOs file payroll tax under their own EIN across all 50 states — and assume sole liability for federal employment taxes.
Digital workflows process new hires in 2–4 days (E-Verify, background, direct deposit, benefits, taxes) vs 8–14 days for legacy paper-based HR.
