# Justworks, TriNet and Insperity

> A buyer-focused comparison of Justworks, TriNet and Insperity argues that choosing a professional employer organization is less about checking feature boxes than choosing an operating model. Justworks emphasizes transparent packaging and a modern single-brand experience, TriNet spans high-touch PEO and the lower-touch HR Platform lineage acquired with Zenefits, and Insperity sells a broad, consultative service relationship. The practical lesson is to price the whole employment system, test the service model and plan the exit before signing.

## Achievements

- Justworks is an IRS-certified PEO and ESAC-accredited.
- TriNet has maintained ESAC accreditation since 1995, and a subsidiary is an IRS-certified PEO.
- Insperity reported 2025 revenue of $6.8 billion and an average 310,089 paid worksite employees.
- TriNet's acquisition of Zenefits extended its range from high-touch PEO service to lower-touch HCM software and ASO service.
- Justworks publicly lists per-employee pricing for its payroll and PEO plans.
