Editor’s take: If you asked our team to pick one for a friend: Justworks. The reason isn't on the comparison table — it's how the product behaves at month six, not week one.
Editor's Take
Two PEOs with different sweet spots: one is the modern, startup-friendly self-service option, the other has deeper industry-specific expertise and broader benefits options for slightly larger companies. If you are under fifty people and want simple, the former fits; if you have complex benefits or industry requirements, the latter is worth the extra cost.

A closer look at pricing
Justworks Pricing
The two PEOs price differently enough that you will need written quotes. Justworks is transparent: Basic costs $59/employee/month and Plus costs $99/employee/month (adds medical, dental, vision, 401k, HSA/FSA, commuter benefits). TriNet quotes custom and structures plans by industry, including technology, financial services, and life sciences, so its number reflects vertical compliance work you may or may not need. Compare TriNet's quote against Justworks Plus rather than Basic, because the Plus bundle is what makes benefits comparable.
TriNet Pricing
TriNet PEO pricing is not published. Similar to Insperity, expect percentage-of-payroll pricing. Industry-specific plans are available (technology, financial services, life sciences, etc.).
Bottom line on pricing: For a 50-employee company, Justworks's total platform cost (including payroll if applicable) is typically around $Basic: $59/employee/month; Plus: $99/employee/month, while TriNet comes in around $Custom quote (typically percentage-based, similar to Insperity). The gap changes significantly depending on which modules you need and your employee count. Always request written quotes from both before deciding.
Interface and day-to-day usability
Justworks Access to enterprise-grade benefits at small-business pricing
TriNet Industry-focused PEO plans — good for tech, finance, life sciences, nonprofits
Under real workloads, the gap shows up in HR admin time. Justworks pushes self-service: employees edit their own records, bank details included, without filing tickets. TriNet defaults to HR-approval flows for changes that other platforms let employees make alone.
Ecosystem and integrations
Justworks integrates with: QuickBooks, Xero, BambooHR, Greenhouse, Slack, Zapier
TriNet integrates with: QuickBooks, Xero, Salesforce
Check your existing accounting, IT, and recruiting tools against what each platform supports natively. A short audit call with IT usually settles which integrations are genuinely in production versus listed as roadmap. A native Justworks or TriNet connector syncs more reliably than anything routed through a third-party bridge.
Onboarding and time-to-launch
Justworks implementation: Justworks implementation is fast — 1–2 weeks for most companies. The PEO model simplifies setup because Justworks handles tax IDs, workers comp, and compliance on their side.
TriNet implementation: TriNet PEO setup takes 2–4 weeks. The industry-specific compliance setup adds value for specialized businesses.
Setup time is a real cost, not a footnote. Include the implementation burden of Justworks versus TriNet in total cost of ownership, next to the subscription.
Which is right for you: Justworks or TriNet?
Choose Justworks if:
- You are Small businesses and startups (2–100 employees)
- Access to enterprise-grade benefits at small-business pricing
- 24/7 HR support with real humans

Choose TriNet if:

The either-or framing is often wrong here. a company might use one tool for HRIS and another for payroll. Whichever platform your data lives in is the one that deserves the budget and the admin time.
