# Justworks vs. TriNet

> Justworks and TriNet sell the same broad promise - fewer hours lost to payroll, benefits, compliance and HR administration - but package it differently. Justworks publishes straightforward per-employee prices and presents one cohesive brand across PEO, payroll and global hiring products. TriNet operates at greater disclosed PEO scale, prices by quote and emphasizes industry-tailored service; the former Zenefits product now sits inside TriNet's HR Platform and HR Plus ASO path, not as a second current PEO brand. The practical buying decision starts with whether co-employment and access to PEO-sponsored benefits are actually needed, then turns on price transparency, service model, benefits fit, integrations and contract details.

## Achievements

- Justworks serves a customer base of more than 14,000 small businesses, according to a 2025 company research note.
- Justworks says it processed $31 billion in payroll and $8.9 billion in taxes in 2025.
- TriNet says it processed $70 billion in payroll and payroll taxes in 2025 and ended the year with approximately 323,200 worksite employees.
- Both companies point to IRS certified PEO status through qualifying entities and ESAC accreditation.
