What are PEO companies?[toc=PEO Overview]
A PEO (Professional Employer Organization) provides outsourced HR services through a co-employment model where it becomes the Employer of Record for payroll, benefits, and compliance. The business keeps control over daily operations while the PEO manages payroll processing, benefits administration, risk management, and adherence to labor laws.

They act as an extension of your team, handling the entire employee lifecycle from onboarding to compliance, so you can focus on growth.
How do PEO companies work?[toc=PEO Process]
A PEO enters a co-employment relationship with your business, sharing responsibility for HR tasks like payroll, benefits, compliance, and risk management. While your company manages day-to-day operations, the PEO handles critical administrative functions to reduce your HR burden.
Key services offered by a PEO include:
- Payroll Processing and Tax Filings: The PEO manages payroll, tax withholdings, and filings, ensuring compliance with federal, state, and local regulations.
- Benefits Administration: PEO services offer access to competitive benefits packages, such as health insurance and 401(k) plans, often at better rates due to pooling employees from multiple clients.
- Compliance Support and Risk Management: PEO helps businesses navigate complex employment laws, reducing the risk of penalties and lawsuits.
- HR Support and Consulting: They provide expert HR advice on employee relations, performance management, and regulatory compliance.
By outsourcing these functions, businesses can focus on growth while ensuring they stay compliant and competitive.

How much do PEO services cost in 2025?[toc=PEO Pricing]
PEO costs range from $100-$200 per employee monthly or 2-8% of total payroll. Small businesses typically pay more per employee than larger companies due to economies of scale.
Two Main Pricing Models:
- Percentage of Payroll: Most PEO companies charge a fixed percentage of total payroll. Smaller companies usually pay 8–12%, while larger ones pay 2–4% as their workforce grows.
- Flat Fee (PEPM/PEPY): A predictable monthly rate per employee, usually $40–$200 per month (or $500–$2,400 yearly). This model suits businesses with higher-salaried staff who want transparent costs.
Key Cost Factors:
- Scope of Services: Payroll-only plans cost less than full HR outsourcing with benefits and training.
- Company Size: Bigger teams qualify for discounts.
- Industry Risk: High-risk sectors pay more due to workers’ compensation.
- Location: Labor laws and payroll taxes vary by state, influencing pricing.
Watch Out for Hidden Costs:
- Setup fees: $200-$1,000 for onboarding
- Technology access: Monthly HRIS platform fees
- Benefits markups: 5-15% added to insurance premiums
- State unemployment fees: $50-$500 per employee annually
- Premium services: $25-$150/hour for consulting
- Exit fees: Early termination penalties
Real ROI:
According to NAPEO, businesses see an average 27% return on investment from PEO services. Most companies save $1,775 per employee annually through reduced administrative costs and better benefit rates.

Why do companies choose PEO services? Key Benefits Explained[toc=PEO Benefits]
Companies use a PEO to simplify HR, payroll, and compliance management while gaining access to better employee benefits and risk protection. For small and mid-sized businesses, it’s a strategic way to scale efficiently without building a full internal HR team.
- Time and Cost Savings: PEO services cut administrative workload and reduce HR overhead, leading to an average 27% annual ROI, according to NAPEO.
- Access to Better Benefits: They give small businesses access to Fortune 500–level benefits at affordable group rates.
- Reduced Liability: PEO shares employer responsibilities and ensure compliance with tax and labor laws, reducing legal and financial risk.
- Business Growth and Stability: PEO-supported businesses grow 2x faster, have 12% lower turnover, and are 50% less likely to fail than those managing HR alone.
How to choose the right PEO company for your business?[toc=Choosing PEO]
Choosing the right PEO company can make or break your HR experience. Here are the key questions every business should ask before signing a contract:
- What HR support do we actually need and what’s our budget?
Start by defining which HR tasks you want to outsource, payroll, benefits, or compliance, and set a clear budget. PEO companeis usually charge either a flat fee per employee or a percentage of payroll, so choose the model that fits your cash flow. - Is the PEO financially stable and certified?
Always check for IRS Certified PEO (CPEO) status or ESAC accreditation, which prove the provider meets industry and financial standards. Ask for independent financial audits and client references in your industry. - What services and technology are included?
Get a list of what’s covered in the standard package and what costs extra. Request a demo of their HR platform, it should be intuitive, secure, and offer employee self-service tools for onboarding, payroll, and benefits. - How strong is their customer support?
Find out if you’ll get a dedicated HR manager or be routed through a general helpline. Ask about response times, communication channels, and client-to-staff ratios to gauge how personalized their support really is. - Are the pricing and contract terms transparent?
Insist on a detailed breakdown of all fees, including setup, add-ons, and potential termination costs. Clarify how fees change with raises or new hires and review renewal or exit terms before committing.
By asking these questions, you’ll quickly identify which PEO providers are transparent, reliable, and equipped to grow with your business.
When is an EOR better than a PEO?[toc=EOR vs PEO]
Use an Employer of Record (EOR) when you need to hire in a country where you don’t have a legal entity; the EOR becomes the legal employer, handles payroll, benefits, and compliance locally, and assumes employment liability. A PEO is for companies that already have an entity (e.g., in the US) and want co-employment support for HR and payroll.
- No entity needed, faster starts: EORs let you onboard employees in new countries without forming a subsidiary, often in days, because the provider already has local infrastructure.
- Liability & compliance shift: With a PEO you share responsibility under co-employment; with an EOR the provider is the legal employer and carries the local compliance risk.
- Multi-country coverage: One EOR can standardize payroll, benefits, and contracts across multiple countries, useful for distributed teams testing new markets.
- When PEO falls short: PEO companies generally require your local entity; if you lack one (or don’t want to set it up yet), EOR is the correct model.
choose PEO for domestic HR and payroll when you already operate locally; choose EOR to hire abroad quickly and compliantly without the cost and delay of entity formation.
