  1. TriNet

    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.

How the score works

What matters for mid-sized companies

  1. Multi-state tax and registration support

    More jurisdictions mean more setups before the first run.

  2. Time and accounting integrations

    Hours and journal entries are high-volume and error-prone when keyed by hand.

  3. Defined cutoff and approval process

    Your internal approvals must fit the provider's submission deadline.

  4. Corrections included

    Volume makes per-item correction fees material.
