Our verdict
TriNet suits small and mid-size businesses that want a PEO with bundled payroll, tax filing, benefits, workers' compensation administration and HR support, or a lighter HR Plus (ASO) service. The trade-off is that neither is priced publicly: both are quote-only per-employee-per-month fees.
