The Short Answer
HR outsourcing cost for a mid-market business with 100 to 500 employees runs $5 to $75 per employee per month depending on service level. Payroll-only processing starts at $5 to $10 per employee per month. Managed HR services including payroll and compliance support run $30 to $50. Full HR outsourcing with UKG Ready software included runs $50 to $75. The number that matters more than the monthly fee is what your current in-house HR setup is actually costing you when you count errors, penalties, staff time, and software licenses honestly. When you run that comparison correctly, outsourcing almost always wins.
Why HR Outsourcing Cost Is Hard to Compare
Most businesses get this comparison wrong because they only look at one side of the ledger. They see the outsourcing fee and compare it against their current HR person’s salary. That is not the right comparison.
The honest number includes your HR person’s salary and benefits, your payroll software license, your compliance subscription, your time and attendance system, the cost of every payroll error that required manual correction, and any penalties you paid because something got filed late or wrong.
Here’s what I’ve learned after almost 25 years in payroll and HCM: the companies that think outsourcing is expensive are almost always doing an incomplete comparison. When every cost gets counted, the math usually flips.
What Does HR Outsourcing Cost Per Employee Per Month?
HR outsourcing is priced on a per-employee-per-month basis. The range depends entirely on service scope. Here is how the three tiers break down for a mid-market company.
| Service Level | Cost Per Employee Per Month | What Is Included |
|---|---|---|
| Payroll only | $5 to $10 PEPM | Payroll processing, tax filings, direct deposit. Single state, clean pay rules. |
| Managed HR services | $30 to $50 PEPM | Payroll plus HR support, compliance monitoring, multi-state capability. |
| Full HRO with UKG Ready included | $50 to $75 PEPM | Complete outsourcing plus software. Healthcare, manufacturing, construction with complex pay rules, multi-shift, union or certified payroll. |
For a 200-person company, full HRO at $75 per employee per month is $15,000 per month or $180,000 per year. Managed services at $50 per employee per month is $10,000 per month or $120,000 per year. Both numbers look very different when you stack them against what in-house HR actually costs at that size.
What Drives HR Outsourcing Cost Up or Down?
Three factors move the number more than anything else.
Number of states. Multi-state payroll is a specialty. Each state has its own registration requirements, tax filings, and labor law nuances. A single-state employer at 200 people is a simpler engagement than a multi-state employer at 150. The more states, the higher the cost.
Pay complexity. Straight hourly pay in one location is simple to process. Multiple pay rates, shift differentials, union dues, certified payroll, PTO accrual rules by location, and overtime calculations across different state thresholds all add configuration time. The more complex the pay rules, the higher the cost.
Technology included. Some outsourcing engagements include the HR platform in the fee. Others charge separately for software and services. At Axiom, UKG Ready implementation and configuration is part of the HRO engagement. You are not managing two separate vendor relationships or two separate invoices.
The Real Cost of In-House HR at 100 to 500 Employees
| Cost Item | Typical Annual Cost |
|---|---|
| Payroll specialist salary plus benefits | $65,000 to $85,000 |
| Payroll software license | $12,000 to $25,000 |
| Time and attendance system | $8,000 to $15,000 |
| Compliance subscriptions and legal reviews | $5,000 to $12,000 |
| Payroll error corrections and reprocessing | $3,000 to $10,000 |
| Compliance penalties when they happen | $2,000 to $50,000+ |
| Total annual in-house cost estimate | $95,000 to $197,000+ |
That is $475 to $985 per employee per year to run HR in-house at 200 people. Divide by 12 and you are at $40 to $82 per employee per month before a single penalty hits.
Managed HR services at $40 per employee per month for the same company gives you a dedicated team of specialists, compliance coverage, and UKG Ready at a comparable or lower cost. That is the comparison most businesses are not running.
What the Sales Rep Won’t Tell You About HR Outsourcing Pricing
Implementation fees are real and they vary. A full UKG Ready implementation for a 200-person company with multi-state payroll and complex pay rules is not a small engagement. Ask every vendor to give you the implementation fee in writing before you sign. If they cannot do that, that tells you how they operate.
Per-employee pricing can have minimums. Some vendors quote $10 per employee per month but require a minimum of 100 employees. If you have 80 people you are paying for 100. Ask about minimums upfront.
Scope creep is where pricing gets messy. A base payroll fee often does not include multi-state registration support, year-end W-2 processing, ACA reporting, or off-cycle payroll runs. Ask for a complete list of what triggers additional charges before you sign.
The math doesn’t lie: the cheapest quote is not the lowest cost. A vendor who misconfigures your pay rules produces expensive errors. A vendor who routes your compliance questions to a call center misses deadlines. The real cost of cheap outsourcing shows up in penalties and reprocessing, not the monthly invoice.
HR Outsourcing Cost by Industry
Industry complexity drives cost more than headcount in most mid-market engagements.
Healthcare and Senior Living
Healthcare employers carry the highest compliance load. PBJ reporting, overtime rules for shift workers, ACA tracking for variable-hour employees, and state-specific scheduling regulations all require configuration a standard payroll engagement does not cover. Full HRO for a senior living facility typically runs at the top of the $50 to $75 range.
Manufacturing
Manufacturing payroll complexity comes from multiple pay rates, shift differentials, safety certification tracking, and in unionized shops, dues calculations and bargaining unit rate management. A 250-person manufacturer with two shifts and union representation is a more complex engagement than a simple hourly workforce. Expect mid-to-upper HRO range pricing.
Construction
Construction adds multi-state complexity on top of everything else. Crews move across jurisdictions. Each one has its own payroll tax registration, labor law requirements, and on public projects, certified payroll obligations under Davis-Bacon or state prevailing wage laws. Multi-state construction payroll is one of the most complex mid-market engagements. Price accordingly.
When HR Outsourcing Cost Is Worth It
The ROI on HR outsourcing is clearest when one or more of these conditions apply.
Your team is spending more than 4 hours per payroll cycle on corrections and reconciliation. At $50 per hour of staff time, 4 hours per cycle adds up to $5,000 per year minimum. That math tips fast.
You have expanded into a new state and nobody on your team has done multi-state payroll before. The first missed filing creates penalty exposure that costs more than a year of outsourcing fees.
You are in healthcare, manufacturing, or construction and your compliance configuration has never been audited by someone who specializes in your industry. The risk in a misconfigured system is almost always larger than the outsourcing fee.
You are about to hire a second HR person because your first cannot keep up. That second hire costs $60,000 to $80,000 per year. Managed HR services at the same cost gives you a team of specialists instead of one generalist.
When HR Outsourcing Cost Is Not Worth It
Not every company should outsource HR. The cost is not justified when you have fewer than 50 employees, operate in one state, run a simple salaried workforce, and payroll runs without drama every cycle. A basic payroll service at $5 to $10 per employee per month may be all you need.
If you already have a clean UKG Ready configuration, a capable internal payroll person, and compliance is current, do not fix what is not broken. We do not manufacture problems to solve.
How to Get an Accurate HR Outsourcing Quote
Before you call a vendor, have these numbers ready. Any firm that cannot give you a firm quote with these inputs is guessing.
Total employee count. Number of states where you have employees. Pay frequency. Number of distinct pay rates or pay structures. Whether you have union employees. Whether you have hourly employees subject to overtime. Your current payroll software and whether you want to keep it or replace it.
Ask every vendor for three numbers in writing: the implementation fee, the monthly service fee, and the complete list of what triggers additional charges. Those three numbers tell you the real cost.
FAQ About HR Outsourcing Cost
How much does HR outsourcing cost per employee per month?
HR outsourcing costs $5 to $75 per employee per month depending on service level. Payroll-only processing runs $5 to $10. Managed HR services including payroll and compliance support run $30 to $50. Full HR outsourcing with UKG Ready software included runs $50 to $75. Industry complexity, number of states, and pay rule complexity all move the number within each tier.
Is HR outsourcing cheaper than hiring in-house?
Usually yes, when you count in-house HR costs correctly. The honest comparison includes the HR specialist salary and benefits, payroll software, compliance subscriptions, time and attendance system, error correction costs, and penalties from missed filings. For a 200-person company, in-house HR runs $95,000 to $197,000 per year before a penalty hits. Managed HR services at $40 per employee per month for the same company is $96,000 per year and includes a team of specialists and compliance coverage.
What is included in a payroll-only outsourcing fee?
Payroll-only outsourcing at $5 to $10 per employee per month typically covers payroll processing, payroll tax filings, and direct deposit for a single-state employer with clean pay rules. It usually does not include multi-state registration, year-end W-2 processing, ACA reporting, off-cycle runs, HR support, compliance monitoring, or time and labor management. Always confirm the full scope in writing before signing.
What is the difference between managed HR services and full HRO?
Managed HR services at $30 to $50 per employee per month adds HR support and compliance monitoring on top of payroll processing. Full HRO at $50 to $75 per employee per month includes everything in managed services plus the HR technology platform. At Axiom, full HRO includes UKG Ready implementation and configuration as part of the engagement. You are not paying separately for software and service.
Are there hidden fees in HR outsourcing contracts?
Some vendors bury fees in contract language. Common hidden costs include per-transaction fees for off-cycle payrolls, state registration fees when you expand, year-end processing fees, and fees for accessing your own data or reports. Ask every vendor to walk you through a complete fee schedule in writing before signing. If they cannot, that tells you something about how the relationship will go.
How much does UKG Ready implementation cost?
UKG Ready implementation for a mid-market company typically runs $15,000 to $50,000 depending on workforce complexity, number of states, number of pay rules, and data migration requirements. At Axiom, implementation is included in the full HRO engagement rather than billed separately. The team that configures your system is the same team that manages it after go-live.
Does HR outsourcing cost more for healthcare or manufacturing companies?
Yes. Healthcare, manufacturing, and construction employers typically pay at the upper end of the HRO range because their compliance complexity is highest. PBJ reporting in healthcare, multiple pay rates and union dues in manufacturing, and multi-state certified payroll in construction all require more configuration and ongoing management than a simple single-state hourly workforce.
Can I start with payroll only and add services later?
Yes. Most mid-market companies start with payroll processing at $5 to $10 per employee per month and expand to managed services or full HRO as the relationship matures. Starting with payroll only and adding compliance monitoring, benefits administration, or full HRO later is a common path. It is easier to expand a working relationship than to restart with a new vendor after a bad experience.
What is the ROI on HR outsourcing?
ROI on HR outsourcing comes from four places: staff time saved on processing and reconciliation, software and subscription costs eliminated, compliance penalties avoided, and payroll errors reduced. Companies that track these numbers before and after an outsourcing engagement consistently see payback within the first year. The ROI is highest in industries with complex compliance exposure because the cost of getting it wrong is largest there.
