Everything you need to know about Professional Employer Organizations — what they are, how they work, what they cost, and whether one is right for your business.
Get a free PEO comparison →A Professional Employer Organization is a company that enters into a co-employment relationship with your business — taking on the administrative employer responsibilities for HR, payroll, benefits, workers' compensation, and compliance. Your employees remain your team and you run your business; the PEO handles the infrastructure. There are over 500 PEOs operating in the United States, serving more than 4 million worksite employees.
Co-employment is the legal framework that makes a PEO relationship work. Under this arrangement, both your business and the PEO share employer responsibilities. You maintain control of your employees' day-to-day work, management decisions, and business operations. The PEO takes on the administrative employer role — processing payroll, filing taxes, providing benefits, and managing compliance. This dual-employer structure allows the PEO to extend its buying power and compliance infrastructure to your business.
According to the National Association of Professional Employer Organizations (NAPEO), PEOs employ approximately 4.5 million people across the US and serve roughly 175,000 businesses. The industry has grown significantly in recent years as HR complexity has increased and the value proposition has become clearer for small and mid-size businesses.
PEOs are most commonly used by companies with 10 to 500 employees. The economics are most compelling in the 25–150 employee range — large enough to benefit meaningfully from pooled benefits purchasing power, but small enough that building an in-house HR infrastructure doesn't yet make financial sense. That said, we've helped companies as small as 5 employees and as large as 400+ find the right PEO solution.
No. One of the most common misconceptions about PEOs is that they take control of your workforce. You retain full control over all business decisions — who you hire, how you manage performance, compensation levels, and all day-to-day direction of employees. The PEO only handles the administrative employer functions: payroll, taxes, benefits administration, and compliance. Your employees remain your people.
PEO pricing typically falls into two models: a percentage of total payroll (usually 2–6%) or a flat per-employee-per-month (PEPM) fee (typically $100–$200 per employee). The right model depends on your payroll structure. Importantly, the cost of the PEO service is often partially or fully offset by savings on benefits, workers' compensation, and reduced HR overhead. Many businesses find their total cost is flat or lower after switching to a PEO.
NAPEO research indicates that businesses using PEOs grow 7–9% faster and have 10–14% lower employee turnover than comparable companies not using a PEO. On a direct cost basis, savings typically come from three areas: benefits (access to large-group rates can save 10–20% on health insurance), workers' compensation (pooled rates typically save 15–30%), and reduced HR overhead (eliminating or reducing internal HR staff). The total savings varies widely by company, but a side-by-side comparison we prepare will show you the exact numbers.
No — our service is completely free to clients. We are compensated by the PEO you ultimately choose, as a standard part of their partner program. This is similar to how a mortgage broker or insurance broker works. Importantly, this does not add to your cost — in fact, because we place multiple clients per year, we carry pricing leverage that typically results in better rates than you could get going direct.
Yes, in most cases. Because a PEO pools the employees of hundreds or thousands of client companies into a single benefits pool, they can negotiate large-group health insurance rates. Small businesses typically access health insurance as a group of 5, 10, or 50 — and pay accordingly. Through a PEO, those same employees may be part of a pool of 50,000 or 100,000 — accessing dramatically better rates and plan designs.
Choosing the right PEO requires evaluating seven key dimensions: pricing and fee structure, benefits quality and carrier options, workers' compensation rates and claims management, HR technology platform, compliance depth in your specific states, implementation support, and service model (dedicated vs. pooled account management). Most businesses don't have the time or expertise to evaluate all of these across 15+ providers — which is exactly why working with an independent broker like us makes sense.
A Certified PEO (CPEO) is a designation issued by the IRS that certifies the PEO meets specific financial, background, and reporting requirements. CPEO certification matters primarily for tax purposes — when you use a CPEO, federal employment tax liability transfers entirely to the PEO, which can simplify your tax situation and reduce risk. Not all PEOs are CPEO certified, and certification isn't always necessary, but it's an important factor we consider when making recommendations.
National PEOs (like ADP TotalSource, Insperity, Justworks, and Rippling) have broad geographic coverage, robust technology platforms, and large benefits pools. Regional PEOs often provide more personalized service, may have deeper expertise in specific states or industries, and can sometimes offer more competitive pricing for smaller companies. The right choice depends on your size, locations, and service priorities — we evaluate both when making recommendations.
The most important questions to ask a PEO include: What is your client retention rate? Who specifically will manage my account? How do you handle workers' comp claims? What is the process for terminating the relationship? What are the conversion options for benefits if we leave? What technology integrations do you support? What is your implementation timeline? We guide clients through all of these questions as part of our comparison process.
Most PEO implementations take 4–8 weeks from signed contract to live payroll. The timeline depends on your company size, the complexity of your benefits setup, and how quickly you can provide the required documentation. We project-manage the implementation process to keep things on track and coordinate between you and the PEO so nothing falls through the cracks.
Yes — switching PEOs is one of the most common reasons businesses come to us. Before switching, we review your current contract for termination provisions and notice requirements, benchmark your current pricing against the market, and identify the right replacement. We then manage the transition timeline to ensure there's no gap in payroll processing or benefits coverage.
Continuity of benefits coverage is a critical part of any PEO transition. We coordinate the timing to ensure there is no lapse in health insurance or other benefits coverage. In most cases, employees experience the transition as a simple open enrollment event — they may get access to better plan options at similar or lower cost.
Yes. Most PEO contracts have termination provisions that allow you to exit with 30–90 days notice. When you leave a PEO, your employees remain your employees — the PEO relationship simply ends. We review contract terms carefully upfront so you understand your exit rights before you sign.
The PEO industry has grown significantly over the past decade. According to NAPEO, the industry now employs approximately 4.5 million people across the US, up from 2.7 million in 2008. Total revenue for the industry exceeds $200 billion annually. Growth has been driven by increasing HR complexity, rising health insurance costs, and growing awareness among small and mid-size business owners of the cost and compliance advantages of co-employment.
Approximately 15–17% of businesses with 10–99 employees currently use a PEO, according to NAPEO data. Adoption is growing as more business owners learn about the model — surveys suggest that awareness and understanding of PEOs remains a primary barrier, with many business owners unfamiliar with how the co-employment model works before speaking with a broker.
Yes — according to research published by NAPEO, businesses that use PEOs grow 7–9% faster than comparable companies not using a PEO, are 50% less likely to go out of business, and have 10–14% lower employee turnover. The research attributes this to better HR infrastructure, more competitive benefits packages for talent retention, and the ability of business owners to focus on growth rather than administrative burden.
PEOs serve businesses across virtually every industry, but they are especially common in professional services, healthcare, technology, construction, staffing, and non-profits. Industries with complex workers' compensation exposure (construction, healthcare) benefit particularly from PEO group rates. Industries competing for talent (technology, professional services) benefit most from the enhanced benefits packages PEOs provide.
