Insperity is a publicly traded professional employer organization (PEO) that has been operating since 1986, originally under the name Administaff before rebranding in 2011. The company uses a co-employment model where it becomes the employer of record for tax and benefits purposes, giving small and midsize businesses access to Fortune 500-level health insurance, 401(k) plans, and dedicated HR support teams. With over 100 offices across the US and roughly $6.6 billion in annual revenue, it is one of the largest PEOs in the country.
The platform covers payroll processing, tax filing, benefits administration, time and attendance tracking, workers comp management, onboarding, performance management, and recruiting tools. Each client gets a dedicated service team with specialists in HR, payroll, benefits, and safety, plus a client liaison as a single point of contact.
The downsides are real. Pricing is not published and runs significantly higher than most competitors, typically $150 to $210 per employee per month. You must use their in-house payroll system with no option to bring your own. Health insurance is locked into UnitedHealthcare, limiting flexibility. Reviews frequently mention rigid administrative processes, inconsistent customer service quality, and unclear communication around pricing and plan details. The platform is US-only with no international payroll or EOR capabilities.
- US small and midsize businesses (5-150 employees) that want a full-service PEO with strong benefits packages and dedicated HR support, especially those without in-house HR teams.
- Companies needing international payroll or global hiring, businesses wanting transparent or low-cost pricing, organizations that prefer to choose their own health insurance carriers, and companies with fewer than 5 employees.
- Fortune 500-level benefits packages that help small businesses compete for talent.
- Dedicated service teams with specialized experts in HR, payroll, benefits, and safety.
- Dependable payroll processing with full federal, state, and local tax filing.
- Pricing is opaque and significantly higher than most PEO competitors.
- Rigid administrative processes that still require manual forms and wet signatures for routine tasks.
- Inconsistent customer service quality with slow response times and high rep turnover.
