Justworks

Overview

Justworks sells integrated HR and payroll software with a certified PEO for small businesses. The PEO page states that Justworks PEO is IRS-certified and ESAC-accredited (with the standard disclaimer that the IRS does not endorse any particular CPEO). Support is described as 24/7 via phone, email, or chat, with free standard HR consulting and optional specialized add-on guidance.

2025 operating volumes stated on the homepage: $31 billion in payroll dollars processed, $8.9 billion-plus in total taxes processed, 268,000+ W-2s generated for PEO customers, and 4,000+ tax localities supported.

The PEO product is modular. PEO Basic covers payroll, tax, workers’ comp access, core HR tools, and support. PEO Plus adds group medical/dental/vision administration and a stack of ancillary benefits. Justworks also markets standalone payroll and international hiring (EOR-style) as separate journeys on the main site.

Pricing

Official published PEPM (no base fee):

• PEO Basic: $79 per employee per month — payroll, compliance, HR consulting/tools, 24/7 support, 401(k), access to time tracking.
• PEO Plus: $124 per employee per month — everything in Basic plus medical/dental/vision administration, HSA/FSA, mental health and fertility benefits as listed.

Plans can be switched. Insurance premiums and add-on products are not included in those PEPM figures. Confirm live pricing on the PEO page before using the numbers in a proposal.

Notes & Limitations

• The PEO page includes a FAQ “What states is Justworks PEO available in?”; the fetched page did not include the answer text. Payroll-tax automation is explicitly “all 50 states.” Treat PEO eligibility as national unless a proposal lists exclusions.
• Benefit-partner availability (One Medical, Kindbody, Talkspace, Health Advocate) can be geography- or plan-limited.
• International employee hiring is a separate product from PEO Basic/Plus contractor add-ons; do not assume PEO covers foreign W-2 employment.
• Help-center integration lists can change; they are only as current as the Justworks article.
