Payroll & HR
TriNet
TriNet is a professional employer organization that provides HR services to small and medium-sized businesses. Founded in 1988, it trades on the NYSE as TNET and sells two distinct offerings: a full-service PEO, under which TriNet handles payroll, benefits, risk, and compliance through a co-employment arrangement, and HR Plus, an administrative services organization that leaves the employer of record unchanged.
The PEO bundles payroll processing and payroll tax compliance, benefits access, risk management, and HR guidance with a platform and personalised support. HR Plus pairs HR, payroll, benefits, and time in one system with certified HR and payroll professionals, and is aimed at businesses that want expert support without co-employment. Industry-specific solutions, partner integrations, and a venture and private equity programme are listed, along with a public ROI calculator.
TriNet reports approximately 323,000 worksite employees as of December 31, 2025, and approximately $70 billion in payroll processed in 2025 across both solutions. It has maintained ESAC accreditation since 1995, a TriNet subsidiary is classified by the IRS as a Certified Professional Employer Organization, and the company is an accredited BBB business. HR Plus has surpassed 40,000 users.
Pricing is not published; an ROI calculator and a sales conversation stand in for a rate card. Support is split by product, with PEO customers and HR Platform or HR Plus customers using different channels, so confirm which offering a quote covers before comparing it with another PEO.
Best for
Small and mid-size employers that want payroll, benefits, and HR compliance handled by one vendor, either with co-employment through the PEO or without it through HR Plus. Owners with no W-2 employees have nothing to place.
