What is a PEO and how does it work?

A Professional Employer Organization (PEO) enters into a co-employment arrangement with your business, handling payroll, HR, workers' comp, and employee benefits under their EIN. You retain full control of daily operations. PEOs typically serve businesses with 5–75 employees across all 50 states. According to NAPEO, there are approximately 487 PEOs in the United States serving roughly 175,000 businesses and 4 million employees.

What is a Master Medical Plan in a PEO?

A Master Medical Plan is a group health insurance plan tied to the PEO's EIN — not available through any broker or on the open market. Small businesses gain access to Fortune 500-level health coverage starting with just 5 employees, typically saving 6–8% compared to open-market rates. The coverage is possible because the PEO pools thousands of employees across all its clients, giving it the purchasing power of a large corporation.

What is pay-as-you-go workers' compensation through a PEO?

Pay-as-you-go workers' comp through a PEO eliminates upfront deposits and year-end audit surprises. Premiums are calculated based on actual payroll each pay period — ideal for construction, manufacturing, healthcare staffing, and businesses with fluctuating headcount. Traditional workers' comp policies require an annual premium deposit and conduct year-end audits that often result in unexpected additional charges.

How is a PEO different from a payroll service like ADP Run or Gusto?

A payroll service only processes payroll. A PEO is a co-employer that handles payroll, HR compliance, benefits administration, workers' comp, hiring, onboarding, and risk management under a single co-employment agreement. PEOs typically provide far more comprehensive HR infrastructure than standalone payroll platforms. The key distinction is the co-employment relationship: a PEO becomes the legal employer of record, while a payroll service does not.

What states do PEOs serve?

Most established PEOs serve all 50 states. Florida specifically requires PEOs to hold a Certificate of Registration from the Florida Department of Financial Services (DFS). Some PEOs have geographic specializations — particularly strong regional PEOs exist across the Southeast including Florida, Georgia, North Carolina, South Carolina, and Tennessee.

How much does a PEO cost?

PEO pricing uses two primary models: (1) a percentage of total payroll, typically 2–12%, or (2) a per-employee-per-month (PEPM) fee of $40–$160. NAPEO research shows average net savings of $1,775 per employee per year — meaning PEO costs are usually exceeded by savings on health insurance, workers' comp, and avoided compliance penalties. For a 20-person company, this represents approximately $35,500 in annual net value.

What is NAPEO and why does membership matter?

NAPEO (National Association of Professional Employer Organizations) is the national trade association for the PEO industry. NAPEO members follow strict financial, legal, and ethical standards. Look for additional IRS CPEO (Certified Professional Employer Organization) status for the highest level of legal protection — CPEO certification means the IRS holds the PEO solely liable for federal employment taxes.

What industries benefit most from PEO services?

Construction, manufacturing, healthcare staffing, restaurants, nonprofits, retail, trucking, dental practices, and legal firms all benefit significantly. Pay-as-you-go workers' comp is especially valuable for construction and trade businesses. Healthcare staffing benefits from complex compliance management. Restaurants and retail benefit from seasonal workforce flexibility and benefits access.

Which PEO is best for small businesses with under 25 employees?

For businesses with under 25 employees, Justworks (transparent pricing, self-service platform) and regional/specialized PEOs tend to outperform national giants like ADP TotalSource, which typically requires 50+ employees for optimal service levels. Key criteria: minimum employee requirements, PEPM vs. payroll percentage pricing, whether a dedicated rep is included, and whether pay-as-you-go workers' comp is available.

What is the difference between a PEO and an ASO (Administrative Services Organization)?

A PEO enters a co-employment relationship — the PEO becomes the employer of record and employees are co-employed. An ASO (Administrative Services Organization) provides HR administration services without co-employment. Under an ASO, you remain the sole employer of record and retain all employer tax liability. PEOs typically offer better access to benefits due to their pooled employee base; ASOs offer more flexibility for businesses that want administrative help without sharing employer status.

All major PEOs operate in New York City, including ADP TotalSource, Paychex PEO, TriNet, Insperity, Justworks, and HRDelivered.

What PEOs serve small businesses in Texas (Houston, Dallas, Austin, San Antonio)?

Houston and Dallas construction businesses especially benefit from pay-as-you-go workers' comp through a PEO.

Which PEOs are best for small businesses in Florida?

Illinois has specific employment laws around pay frequency, final pay, and leave entitlements that a PEO will handle. PEPM pricing models tend to work well for Midwest businesses with stable headcount.

The region's construction and healthcare staffing industries make pay-as-you-go workers' comp particularly valuable.

Do PEOs serve small businesses in smaller metros like Boise, Reno, or Spokane?

Yes. Most established PEOs operate in all 50 states, including smaller metros like Boise (ID), Reno (NV), Spokane (WA), Fayetteville (NC), and others.

Remote-capable PEOs have expanded coverage significantly since 2020.

What PEO services are available in Denver and Colorado?

Denver and Colorado small businesses benefit from PEOs that handle Colorado's specific employment laws, including FAMLI (paid family and medical leave), Colorado HELP rules, and COMPS Order wage requirements. All major national PEOs serve Colorado. For construction businesses in Denver, Aurora, and Colorado Springs, pay-as-you-go workers' comp through a PEO provides significant cash flow advantages.

Which PEOs serve businesses in the Pacific Northwest (Seattle, Portland, Tacoma)?

Seattle, Portland, and Tacoma are strong PEO markets driven by complex Washington and Oregon employment laws — including Washington's L&I workers' comp (state-run monopoly), paid family leave, and Oregon's predictive scheduling laws. Most national PEOs serve the Pacific Northwest. TriNet serves Seattle's tech sector. Washington's state-run workers' comp means PEOs there coordinate differently than in other states.
