HR Outsourcing Pricing Models: What Small Businesses Actually Pay in 2026
The number isn’t the problem. The model is.
Most small businesses looking at HR outsourcing for small businesses get a quote and compare it to what they’re currently spending. That comparison almost always misses the structure behind the number. A $90/employee quote from a PEO and a $90/employee quote from an HRO platform are not the same thing. The first makes you a co-employer. The second gives you tools. Neither gives you a person unless you ask for one specifically.
This guide breaks down what each model actually costs, how the math changes by company size, and which model fits which stage of growth.
What Small Businesses Actually Pay for HR Outsourcing
The range is wide because “HR outsourcing” covers a lot of ground. A basic payroll-only arrangement at $30 per month plus $5 per employee per run is technically HR outsourcing. So is a full PEO relationship that costs 8% of total payroll and places your employees on the PEO’s benefits plan.
Most small businesses (10 to 100 employees) fall somewhere in between. Based on industry pricing data from TriNet, NAPEO, and Soteria HR, here’s where most small businesses land:
| Service Scope | Model | Typical Cost Range | What’s Included |
|---|---|---|---|
| Payroll only | Per run + base | $30/mo base + $4 to $6/employee/run | Payroll processing, tax filings, direct deposit |
| HR platform (basic) | PEPM | $50 to $90/employee/mo | Payroll, compliance helpline, employee portal |
| HR platform (full) | PEPM or % payroll | $100 to $200/employee/mo | Payroll, benefits admin, recruiting tools, performance mgmt |
| PEO (co-employer) | % of payroll | 2% to 8% of total payroll | Full HR + benefits purchasing power + co-employment |
| Dedicated offshore hire | Flat monthly | $1,800 to $2,500/mo | Full-time HR professional, your direction, flat rate |
The 4 HR Outsourcing Pricing Models Explained
Four structures dominate the small business market. Each has a different risk profile depending on how your company grows.
Per Employee Per Month (PEPM)
You pay a fixed dollar amount for every employee on your payroll, every month. The rate usually drops as headcount grows, but every new hire increases the bill automatically. It’s predictable at a given headcount. It penalizes growth.
A 25-person company paying $120/employee runs $3,000/month. When they hire 10 more, that’s $4,200/month with no change in what they receive. The pricing model scales with their growth, but the value doesn’t necessarily.
Percentage of Payroll
Your HR costs track directly with total payroll. Simple math. Unpredictable over time, especially as you add senior roles or give raises. A $300,000 monthly payroll at 5% means $15,000/month in HR fees. Approve a $20,000 raise across the team? Your HR bill goes up $1,000/month without a single new service.
Flat Retainer
A fixed monthly fee regardless of headcount or payroll changes. Usually scoped to a defined set of services: payroll processing, compliance calendar, handbook maintenance, and a set number of consulting hours. Good for companies with stable headcount who want budget certainty. The risk is scope creep. Every need outside the defined scope triggers an add-on charge.
Project-Based or Hourly
Used for discrete HR work: an I-9 audit, a handbook rewrite, a job description library build. Rates run $75 to $250/hour depending on provider seniority and geography. Not viable as a primary HR model for a company doing regular hiring, but useful as a supplement for companies with an internal HR lead who needs occasional specialist support.
HR Outsourcing Cost by Company Size
Pricing behavior changes significantly by headcount. Here’s how each model typically performs across the common small business size bands, using published ranges from Soteria HR and NAPEO member pricing data:
| Company Size | PEPM Range | Est. Monthly Cost | Offshore HR Hire | Savings Potential |
|---|---|---|---|---|
| 5 to 10 employees | $80 to $180/employee | $400 to $1,800/mo | $1,800/mo | Low at this size |
| 11 to 25 employees | $75 to $160/employee | $825 to $4,000/mo | $1,800 to $2,000/mo | Moderate to strong |
| 26 to 50 employees | $65 to $130/employee | $1,690 to $6,500/mo | $2,000 to $2,200/mo | Strong |
| 51 to 100 employees | $55 to $120/employee | $2,805 to $12,000/mo | $2,200 to $2,500/mo | Very strong |
Below 10 employees, the offshore model rarely wins on pure cost alone. The PEPM bill at that size is often small enough that the overhead of managing a dedicated hire doesn’t make sense. Above 25 employees, the math shifts. The flat-rate model stops being more expensive and starts being significantly cheaper.
PEO vs HRO vs Offshore: A Direct Cost Comparison
The terminology causes real confusion. Here’s a plain-English breakdown of what each model is, what it costs, and where the hidden tradeoffs live.
| Model | Structure | Typical Cost | Best For | Watch Out For |
|---|---|---|---|---|
| PEO | Co-employer. They’re on the hook for employment compliance alongside you. | 2% to 8% of payroll | Small businesses needing group benefits rates | Loss of hiring control, co-employment complexity, hard exit |
| HRO / Platform | Vendor relationship. You’re the sole employer. | $50 to $200 PEPM | Companies wanting compliance tools + shared support | Add-on fees, shared service team, no dedicated person |
| Offshore Dedicated Hire | Your employee (managed by Kore BPO). You direct the work. | $1,800 to $2,500/mo flat | Companies above 20 employees who need real HR capacity | Requires active management from your side |
According to NAPEO’s 2024 research, companies using PEOs see an average 27.2% ROI when accounting for cost savings, error reduction, and compliance protection. That figure is real, but it’s built heavily on the benefits purchasing advantage. For companies that already offer competitive benefits independently, the PEO arithmetic changes significantly.

The In-House vs Outsourced Math
The honest comparison isn’t “what does outsourcing cost.” It’s “what does HR cost right now, fully loaded, versus what outsourcing would cost for the same scope.”
Most small businesses undercount their current HR spend. Here’s the real math for a company with 30 employees currently managing HR with one part-time internal person:
| Cost Element | In-House (Part-Time HR) | Platform HRO | Offshore Dedicated Hire |
|---|---|---|---|
| Direct labor cost | $35,000 to $55,000/yr | $0 (subscription) | $21,600 to $30,000/yr |
| Payroll taxes (7.65%) | $2,678 to $4,208/yr | Included | Included in Kore BPO fee |
| Benefits | $8,000 to $15,000/yr | Included | Included in Kore BPO fee |
| HR software (HRIS, ATS) | $3,000 to $8,000/yr | Included in PEPM | Use your existing tools |
| Platform subscription | $0 | $36,000 to $72,000/yr | $0 |
| Total annual cost | $48,678 to $82,208/yr | $36,000 to $72,000/yr | $21,600 to $30,000/yr |
The Bureau of Labor Statistics puts the median US HR specialist salary at $67,650 as of 2024. Fully loaded with benefits and payroll taxes, that’s closer to $85,000 to $95,000 annually. A senior HR manager runs $90,000 to $120,000 fully loaded. The offshore model isn’t cutting corners. It’s accessing the same capability at offshore labor market rates.

How to Choose the Right Pricing Model for Your Stage
The wrong frame is “which model is cheapest.” The right frame is “which model fits the way my company actually works right now.”
| Your Situation | Best Model | Why |
|---|---|---|
| Under 10 employees, HR is less than 2 hours/week | Payroll-only or basic PEPM | Not enough volume to justify more |
| 10 to 25 employees, growing fast, HR is 5+ hours/week | HRO platform or offshore hire | Need compliance coverage + capacity, not just tools |
| 25 to 75 employees, benefits cost is the main pain | PEO | Group buying power is the real win here |
| 25+ employees, want full-time HR person you direct | Offshore dedicated hire | Flat rate, full control, no co-employment |
| 75+ employees, compliance is complex and growing | Mix: offshore hire + compliance platform | Dedicated capacity plus systematic coverage |

What You’re Actually Risking if You Get the Model Wrong
The cost of the wrong model isn’t just overpaying. It’s the downstream problems the wrong structure creates.
A PEO arrangement you enter at 20 employees can become genuinely difficult to exit at 80 employees. The co-employment structure, the benefits platform, and the vendor lock-in around your employee data create real switching costs. Not impossible to exit, but not frictionless either.
A platform HRO at $120/employee at 50 employees is $6,000/month. Add two premium modules, and you’re at $8,400/month. The platform is still technically cheaper than a full in-house hire, but the comparison against a flat-rate offshore model starts looking very different.
The US Chamber of Commerce notes that 60% of employment-related lawsuits target companies with fewer than 100 employees. Hiscox puts the average cost of a defended employment lawsuit at $75,000 to $125,000. A compliance miss that a proper HR structure would have caught isn’t just expensive. It’s the kind of expensive that changes the trajectory of a small business.
The HR outsourcing cost conversation almost always focuses on the monthly invoice. The real number worth calculating is what a compliance gap, a bad hire, or a payroll error costs when it happens. That context changes what “worth it” means.
What Small Business Owners Ask Before Signing an HR Contract
What’s the average cost of HR outsourcing for a 10-person business?
About $550 to $1,800 per month for basic services at that size, using PEPM pricing in the $55 to $180 range. The lower end covers payroll and basic compliance. The higher end adds benefits administration and onboarding support. A dedicated offshore HR hire at that headcount runs $1,800/month, which is competitive with the upper end of platform pricing while giving you a full-time person instead of a shared service queue.
PEPM or percentage of payroll — which is better when you’re growing fast?
Depends on your wage mix, not just headcount growth. If you’re adding senior roles with high salaries, PEPM is safer. Your HR cost doesn’t move when you approve raises. Percentage of payroll works better when adding lower-wage hourly employees at volume, where salaries are stable but headcount grows. Most high-growth companies find PEPM more predictable because salary increases happen more frequently than headcount changes.
Does the quoted price include payroll processing, or is that separate?
Not automatically. Payroll-only arrangements typically run $30 to $50/month as a base fee plus $4 to $6 per employee per payroll run, often priced separately from broader HR outsourcing packages. Always ask for a full itemized quote before comparing vendors. The base PEPM rate and the fully-loaded PEPM rate can differ by 30% to 60% once add-ons, software modules, and per-run fees are included.
PEO vs. HR outsourcing company — does the distinction matter for a small business?
The employer relationship, mostly. A PEO becomes your co-employer on paper and shares compliance liability. An HRO or managed HR provider works as a vendor while you stay the sole employer. The practical difference shows up most in benefits pricing: PEOs pool clients for group rates 30% to 40% below individual market. For companies where benefits cost is the primary pain, the PEO structure has genuine advantages. For companies that want full hiring authority and no co-employment complications, HRO or a dedicated hire wins.
Are there setup fees or other costs that don’t show up in the PEPM quote?
Yes, and some vendors aren’t upfront about them. Setup and onboarding fees run $500 to $2,000 for most arrangements, up to $6,000 for complex ones. Technology fees of $500 to $3,000 per year sometimes sit outside the PEPM. Premium support tiers, multi-state compliance modules, and ATS integrations can add $20 to $60/employee/month on top of the base rate. Always ask for the full all-in monthly number before signing.
How do I know if HR outsourcing will actually save money before committing?
Run the comparison before the vendor call. Start with your real in-house cost: salary, payroll taxes (7.65%), health benefits, software, and management time at $100 to $150/hour. Then compare against an outsourced quote for the same scope. The outsourcing ROI calculator can do this math for your specific headcount. NAPEO’s 2024 research puts the average ROI for professional HR outsourcing at 27.2% when accounting for cost savings, error reduction, and compliance protection.
