How does Justworks pricing compare to TriNet?

Justworks publishes flat-rate pricing of $59 to $99 per employee per month depending on the plan. TriNet uses custom pricing based on industry, employee count, and benefits selected — a quote is required. In practice, TriNet can be competitive for businesses in its target industries, but the lack of published rates makes upfront comparison difficult. Justworks has a clear transparency advantage.

Does TriNet specialize in specific industries?

Yes. TriNet is known for its industry vertical specialization, particularly in technology, life sciences, financial services, professional services, and nonprofits. The company builds industry-specific benefit packages and has HR specialists with expertise in the compliance requirements of each vertical.

Is Justworks or TriNet better for a 25-person startup?

For a typical 25-person startup, Justworks is usually the recommendation. The flat-rate pricing is easy to budget, onboarding is fast, and health insurance access is competitive. TriNet is the better choice if the startup is specifically in technology or life sciences and wants PEO support from a provider with deep expertise in those sectors.

Are both Justworks and TriNet IRS CPEO certified?

Yes. Both Justworks and TriNet hold IRS Certified PEO (CPEO) status. Both assume sole liability for federal employment taxes, undergo annual audits, and meet IRS compliance and financial standards. CPEO status is not a differentiator between these two — both are certified.
