    HR Outsourcing in 2025: Pricing, PEO vs HRO vs EOR, and How to Choose

    Written by October 20, 2025

    U.S. teams face a stubborn reality in 2025. Growth targets are up. Hiring remains competitive. Compliance gets more complex every year, and nobody has extra hours to manage it all. 

    Add to that the uncertainties in offshore outsourcing policies.

    Done right, HR outsourcing gives you leverage, cost control, and risk management without slowing execution. Done wrong, you end up with a vendor relationship that creates more problems than it solves.

    In this guide, you will get a clear definition of HR outsourcing, exactly how PEO, HRO, and EOR differ, what it costs, how it reduces costs in practice, and what you should never outsource. You will also find a no-nonsense roadmap to implement in 90 days, plus a scorecard to pick the right partner.

    Key Takeaways

    • A Strategic Choice, Not Just Administrative Offloading: HR outsourcing in 2025 is a strategic decision that allows businesses to gain cost control, expert-level compliance management, and the flexibility to scale. It frees up internal leadership to focus on core business growth rather than complex, non-revenue-generating HR tasks.
    • PEO, EOR, and HRO Solve Different Problems: It is critical to understand the difference between the three main HR outsourcing models.
      • PEO (Professional Employer Organization): A co-employment model in the U.S. that bundles payroll, benefits, and compliance for a company’s existing domestic workforce.
      • HRO (Human Resources Outsourcing): A modular service model where a company delegates specific tasks (like payroll) to a vendor, but the client remains the sole employer and retains all legal liability.
      • EOR (Employer of Record): A model where the provider acts as the sole legal employer for your staff in a country where you do not have a legal entity. This is the correct model for most international/offshore hiring.
    • Pricing Varies by Model and Complexity, Not Just Headcount: The cost of HR outsourcing is not a single flat fee. PEOs often charge a percentage of payroll (2-12%). HROs typically charge per-employee-per-month (PEPM) based on services selected ($50-$200). EORs charge a flat PEPM fee ($300-$1,500) that covers all compliance and infrastructure in a foreign country.
    • You Can Outsource Execution, But Never Accountability: A business can and should outsource transactional work like payroll, benefits administration, and compliance filings. However, a company must always retain in-house control over its core company culture, executive compensation strategy, and final accountability for high-risk decisions like terminations and legal compliance.

    What Is HR Outsourcing?

    HR outsourcing is the practice of delegating some or all human resources operations to a third-party provider while your company remains the employer and keeps accountability for core decisions. You stay in charge. They handle the machinery.

    In the U.S., this typically covers payroll, benefits administration, HRIS and systems support, compliance filings, leave administration, employee relations guidance, and recruiting add-ons. Think of it as surgical offloading. You pick what drains time without adding strategic value, and you hand it to people whose entire job is doing that work well.

    When Companies Consider HR Outsourcing

    Common triggers include multi-state expansion, a first benefits plan, new payroll complexity, audits or penalties, a lean HR team, or a shift to a more scalable operating model. The decision usually comes down to a simple question: do we want to build this capability in-house, or do we want to buy it from someone who already has it dialed in?

    HR Outsourcing vs Adjacent Models at a Glance

    Here is where things get confusing fast. HR outsourcing is not the same as using a PEO. A PEO is not the same as an EOR. The models share some overlap, but the differences matter. A lot.

    ModelLegal EmployerCo-EmploymentPayroll Taxes & FilingsBenefits AccessGeographyTypical Use Cases
    HRO (Human Resources Outsourcing)ClientNoProvider handles as a service, client remains employerClient plan or provider supportU.S. or global, where client has entitiesModular outsourcing, augment in-house HR
    PEO (Professional Employer Organization)Shared, co-employmentYesPEO administers payroll taxes and filings as co-employerAccess to PEO master plansPrimarily U.S. entitiesSmall to mid-size firms seeking benefits leverage and admin offload
    EOR (Employer of Record)EORNoEOR is legal employer in country, runs payroll and taxesEOR plansCross-border hiring without your entityHiring in countries where you lack an entity

    For PEO buyers, IRS Certified PEO (CPEO) status provides specific federal employment tax protections and process standards. Verify a provider’s status on the IRS CPEO public list, review the program overview, and see the final regulations. This is not optional due diligence. This is the first thing you check.

    PEO vs HRO vs EOR, Explained

    Let me walk you through each model the way I would explain it if you asked me over coffee. The differences are not academic. They change who owns what risk, who controls what decisions, and how much flexibility you keep.

    Professional Employer Organization (PEO)

    How co-employment works. In a PEO, you and the PEO share employer responsibilities. The PEO runs payroll, remits and files payroll taxes, administers benefits, and provides HR compliance support. You direct day-to-day work and make core employment decisions. Co-employment is a legal arrangement, not just a service agreement. It means both parties have skin in the game.

    CPEO certification. The IRS CPEO program sets financial and operational standards for PEOs. Certification can reduce wage-base restarts and provides federal tax payment assurances. Confirm a vendor’s status on the IRS CPEO listings and review the certification rules. Fewer than 7% of PEOs in the U.S. are certified, which tells you something about the rigor involved.

    Buyer fit, advantages, trade-offs. PEOs fit companies that want turnkey HR administration, competitive benefits access, and a single platform. You get economies of scale you could not achieve on your own. Small businesses using a PEO can offer benefits packages that look like Fortune 500 plans. Trade-offs include less customization on benefits design and the realities of co-employment, which some companies find constraining.

    Human Resources Outsourcing (HRO)

    Modular model, no co-employment. HRO lets you outsource selected HR functions while keeping the employer role solely in-house. Typical bundles include payroll, benefits administration, HRIS, leave, and ER support. Control stays with your HR leader, customization is higher, and vendor accountability is defined by SLAs. You are not sharing employment. You are delegating tasks.

    Buyer fit, advantages, trade-offs. HRO fits firms with HR leadership in place who want to scale faster, standardize processes, or consolidate vendors without entering co-employment. Trade-offs are fewer economies of scale than a PEO master plan and the need to manage vendor governance. You keep flexibility, but you also keep more of the risk.

    Employer of Record (EOR)

    Legal employer outside your footprint. An EOR becomes the legal employer in the target country, handling contracts, payroll, taxes, and statutory benefits. Your team directs the work. This is ideal for hiring in countries where you do not have an entity. 

    The EOR is the employer on paper. You are the employer in practice.

    When EOR is right vs PEO/HRO. Use EOR for quick cross-border hiring or market tests. If most headcount sits in the U.S. and you need benefits leverage and admin relief, a PEO or HRO is usually a better fit. EORs solve a different problem than PEOs or HROs, and trying to use one model to solve the other’s problem creates friction.

    Decision Matrix

    Use these factors to select a model. If multiple apply, choose the model that satisfies the most must-haves with the fewest trade-offs.

    Entity footprint. No entity in target country favors EOR. U.S. entity favors PEO or HRO.

    Benefits leverage. If you need pooled buying power and simplified benefits, PEO wins.

    Liability appetite. If you want federal tax payment assurances and tight payroll controls, consider a CPEO.

    Internal HR maturity. Mature HR teams often prefer HRO for control and modularity.

    Headcount and growth rate. Rapid scale or multi-state growth pushes toward PEO or HRO standardization.

    Compliance complexity. Heavy wage-and-hour risk, ACA/COBRA exposure, or classification risk argues for a partner with deep compliance processes.

    Rules of thumb:

    • Mostly U.S. hiring, limited HR capacity, need benefits leverage, and want one throat to choke? Pick PEO.
    • Solid HR leadership in place and want surgical offloading or consolidation? Pick HRO.
    • Hiring where you lack entities? Pick EOR.

    How Much Does HR Outsourcing Cost?

    Pricing is where most buyers get stuck. Vendors are not always transparent, and quotes vary wildly depending on how you structure the relationship. Here is what you need to know to evaluate proposals intelligently.

    Three common pricing models:

    PEO, percent of payroll. Many PEOs quote a percentage of gross payroll. The percentage reflects benefits level, industry risk, and states of operation. Standard range is 2% to 12%, with smaller companies paying higher percentages and larger companies negotiating lower rates.

    HRO, per-employee, per-month (PEPM). HRO fees typically follow a PEPM structure based on the modules you select, with tiering by headcount and complexity. Typical range for SMBs is $50 to $200 PEPM, with basic services at the low end and comprehensive HR support at the high end.

    EOR, flat fee. EORs typically charge a flat PEPM fee that covers all employment infrastructure. Fees generally start around $300-$500 per employee per month and can go up to $1,500 depending on the country and complexity of services. The fee covers all employment infrastructure: payroll, taxes, statutory benefits, compliance, and local HR support. Setup costs are usually lower than establishing your own entity, and you avoid ongoing legal and accounting fees in the target country.

    What drives cost:

    Industry and risk profile. Higher workplace risk or turnover can raise rates. Construction, hospitality, and healthcare often pay more than professional services.

    States of operation. Multi-state payroll and SUI history affect pricing. California, New York, and states with complex wage-and-hour laws add cost.

    Benefits selections. Medical plans and contributions change the total cost materially. Rich benefits increase both the PEO fee and the underlying premiums.

    Payroll complexity. Multiple earnings types, overtime, and garnishments add scope. Simple payroll is cheaper to run than payroll with heavy complexity.

    HRIS scope. Time, attendance, device management, and integrations raise PEPM. Basic HRIS is one price. Fully integrated tech stack is another.

    Headcount. Volume discounts typically kick in as you scale. Pricing tiers shift at 25, 50, 100, and 250 employees.

    Entity setup costs avoided. If you need to hire in a country where you lack a legal entity, an EOR eliminates the significant cost and time required to establish a local subsidiary, plus ongoing legal, accounting, and compliance fees.

    Add-ons to watch. Recruiting, high-risk ER investigations, advanced compliance projects, ACA reporting, COBRA administration, and multi-state setup can be priced outside base fees. Clarify all exclusions. Setup fees can range from $1,000 to $10,000, and you need to know if that is in the quote or tacked on later.

    Sample Pricing Scenarios

    These scenarios illustrate how quotes move as complexity changes. Numbers are representative based on 2024-2025 market data.

    Scenario A: 20-employee startup, single state.

    You are a SaaS company in Texas with 20 employees, all full-time, all in one state. Payroll is straightforward. You want basic benefits, payroll processing, and compliance support.

    HRO pricing: Expect $60 to $100 PEPM, or $1,200 to $2,000 per month total. Annual cost: $14,400 to $24,000.

    PEO pricing: Expect 8% to 10% of gross payroll. If average salary is $75,000, total payroll is $1.5 million. PEO fee: $120,000 to $150,000 annually. This includes benefits administration and access to pooled benefits plans.

    Scenario B: 120-employee multi-state firm.

    You are a professional services firm with 120 employees across five states. You have multiple pay schedules, commission structures, and a mix of exempt and non-exempt workers. You want comprehensive benefits, ACA reporting, COBRA administration, and multi-state compliance support.

    HRO pricing: Expect $90 to $150 PEPM, or $10,800 to $18,000 per month total. Annual cost: $129,600 to $216,000. Add-ons for ACA reporting, COBRA, and multi-state setup could add another $15,000 to $30,000.

    PEO pricing: Expect 4% to 6% of gross payroll. If average salary is $85,000, total payroll is $10.2 million. PEO fee: $408,000 to $612,000 annually. This includes multi-state support, ACA and COBRA compliance, and access to better benefits pricing due to pooled leverage.

    Scenario C: 15-employee offshore team in the Philippines.

    You are a U.S. SaaS company that wants to build a customer support and back-office team in the Philippines. You have no legal entity there. You need to hire quickly. You want to test the market before committing to a permanent presence.

    Setting up a Philippine entity would be a costly and time-consuming process requiring ongoing legal, accounting, and HR infrastructure. You would also need local expertise to navigate payroll, statutory benefits (like 13th-month pay), and labor law compliance. That is a heavy lift for a market test.

    EOR pricing: Expect $300 to $500 PEPM per employee. For 15 employees, this would be $54,000 to $90,000 annually. 

    The EOR handles all employment infrastructure: local payroll, tax filings, statutory benefits (13th month pay, SSS, PhilHealth, Pag-IBIG), compliance with Philippine labor law, employment contracts, and local HR support. You get operational in 30 days. You avoid entity setup costs, ongoing legal fees, and local accounting overhead. If the team works, you scale. If it does not, you exit without unwinding a legal entity.

    The math is straightforward. You trade the fixed cost and time investment of building local infrastructure for a variable cost tied to headcount. You keep flexibility. You reduce risk. You move fast.

    Request itemized quotes that separate base fees from add-ons, and ask vendors to model at least two benefits tiers to show the swing in total cost. Pricing opacity is a red flag. If a vendor will not give you transparent pricing early, walk.

    How Does HR Outsourcing Reduce Costs?

    The question is not whether HR outsourcing costs money. It does. The question is whether it costs less than the alternative, and whether it reduces risk enough to justify the investment. Here is how the math works in practice.

    Direct savings:

    Streamlined payroll processing and tax filings. Running payroll in-house requires software, staff time, training, and error correction. Outsourcing consolidates that into a fixed PEPM or percentage-of-payroll fee. You trade variable costs and risk for predictable expense.

    Benefits purchasing power and simplified administration. PEOs aggregate employees from all their clients into a single large pool. This scale gives them leverage when negotiating with insurance carriers. Clients often see 10% to 30% savings on benefits premiums compared to what they could secure independently. That is real money.

    HR tech consolidation, fewer licenses and vendors. You stop paying for separate HRIS, payroll, ATS, and benefits platforms. The provider includes the tech stack in the service fee. You get one login, one vendor relationship, one invoice.

    Risk-adjusted savings:

    Fewer wage-and-hour penalties, stronger classification practices, and better audit readiness. Wage-and-hour mistakes are expensive. Misclassification is expensive. Failed audits are expensive. A good provider reduces exposure in all three areas. The savings come from avoiding penalties you would have paid otherwise.

    Smoother COBRA and ACA workflows to reduce fines and rework. COBRA notice failures can cost $110 per day per affected person, and that adds up fast. ACA penalties for missing Summary of Benefits and Coverage filings hit $1,443 per failure in 2025. Outsourcing does not eliminate liability, but it reduces execution risk.

    Productivity ROI:

    Time back for executives and HR leaders. Time is finite. Every hour spent fixing payroll errors or answering benefits questions is an hour not spent on strategy, culture, or hiring. The productivity gain is hard to quantify, but it is real.

    Faster hiring cycles with standardized processes. Onboarding takes less time when the provider handles background checks, I-9 verification, and benefits enrollment. You get new hires productive faster.

    Fewer errors and rework through SLAs, checklists, and parallel runs. Providers run parallel payrolls during cutover to catch errors before they hit employees. That level of rigor is hard to maintain in-house.

    Finance-ready takeaways.

    Lower unit costs for payroll and benefits administration. Reduced variability in SUI and penalty exposure. Clear PEPM or percent-of-payroll budgeting for forecasting. Finance teams like predictability, and outsourcing delivers it.

    Recent industry research finds PEO clients grow faster, have lower turnover, and are less likely to go out of business than non-PEO firms, which can amplify ROI assumptions. Annual employee growth rate for PEO clients is 4.3% versus 1.9% for comparable non-PEO firms. Turnover is 12% lower. Business failure rate is 50% lower. Those are not marginal differences.

    What HR Functions Should Not Be Outsourced

    Keep strategic control in-house and define vendor boundaries. Outsourcing works when you delegate execution, not when you abdicate accountability. Some functions are so deeply tied to your identity, culture, and risk profile that handing them off creates more problems than it solves.

    Culture leadership and employer brand voice. Vendors can support, but your leaders must own the message and behaviors. Culture is the soul of the organization, and you cannot authentically manage it from outside. Your values, your rituals, your tone, your identity—those have to come from you.

    Executive compensation strategy. Outside benchmarking helps, but decisions should stay with your board and executive team. How you pay senior leaders, how you structure incentives, how you align comp with performance—those are governance decisions, not HR admin tasks.

    Sensitive employee relations investigations and high-risk terminations. Outside counsel or trusted ER specialists can advise, but ownership and final calls stay inside. You need context only your leadership team holds. The nuance of your culture, the history of your people, the risk tolerance of your organization—those do not translate well to a third party.

    Strategic workforce planning, succession, and leadership coaching. These require context only your leadership team holds. Strategic workforce planning links talent strategy directly to business strategy, and that is a core C-suite activity. You cannot outsource the decision of where you are going or who you need to get there.

    Final accountability for FLSA classification and policy decisions. Partners can advise, you own the decisions and outcomes. Classification is a judgment call based on the economic realities of the relationship, and you are the one who knows those realities. A vendor can give you frameworks and guardrails, but they cannot make the call for you.

    What to offload safely. Payroll, tax filings, routine benefits administration, leave tracking, onboarding workflows, HRIS operations, and first-line HR ticketing are efficient to outsource with the right controls. These are repeatable, process-driven tasks where quality depends on execution, not context.

    Compliance Guardrails: U.S. Buyers Cannot Outsource Away

    Even with a partner, you retain responsibility for core employer obligations. This is not a technicality. This is the law. The Department of Labor and the IRS do not care what your contract says. They care who controls the employment relationship, and in most cases, that is you.

    Wage and hour, employment relationship. Understand how the Department of Labor evaluates whether a worker is an employee under the FLSA. See FLSA Fact Sheet #13. The analysis looks at economic realities, not labels. Control matters. Economic dependence matters. Your contract with a vendor does not change the underlying employment relationship.

    Joint-employer exposure. Know how joint employment is assessed and how policies and supervision affect risk. If you set schedules, approve time off, direct day-to-day work, or control pay rates, you are probably a joint employer. That means you are on the hook for wage-and-hour compliance even if the vendor runs payroll.

    Payroll tax filings and CPEO protections. If you choose a PEO, confirm CPEO status on the IRS CPEO list and review how certification affects federal employment tax handling under 26 CFR §31.3511-1. Certification shifts federal tax liability to the CPEO, which is a meaningful protection. Without it, you are still on the hook if the PEO does not remit.

    COBRA obligations. If your plan is subject to COBRA, ensure timely notices, elections, and premium administration. See the DOL COBRA overview and the Employer’s Guide. Vendors can administer COBRA, but the employer remains legally liable for failures. If the vendor misses a notice deadline, you pay the penalty.

    Helpful references are linked throughout for quick verification. Use them.

    Implementation Roadmap, 0–90 Days

    Implementation is where most outsourcing relationships either lock in or fall apart. You can have the right model, the right vendor, and the right pricing, and still fail if you do not execute the transition well. Here is how to avoid that.

    Vendor Due Diligence Checklist

    CPEO verification (if selecting a PEO) via the IRS CPEO list. References from clients in your industry and size range. SOC 2 reports to confirm security controls. SLAs for ticket response and payroll accuracy, in writing, with penalties for misses. Data security controls and breach notification procedures.

    Discovery and Scoping

    Payroll complexity, earnings types, and states. Map every earnings type, every garnishment, every state-specific rule that affects your payroll. If you miss something in discovery, you find out during cutover, and that is expensive.

    Benefits strategy by persona and market. Not every employee values the same benefits. Know who you are trying to attract and retain, and design the benefits strategy around that.

    Multi-state or global hiring map. Where are you now, and where are you going? The provider needs to support your growth trajectory, not just your current footprint.

    HRIS integrations, SSO, and device policies. How does the provider’s tech stack integrate with your existing systems? Can employees use SSO, or do they need separate logins? What happens to mobile device management?

    Cutover Plan

    Data migration and parallel payroll. Run at least one full payroll cycle in parallel before you cut over. Catch the errors when they do not hit employee paychecks.

    Handbook and policy alignment to vendor workflows. Your handbook references processes that may change when you outsource. Update it before employees notice the disconnect.

    Employee communications and manager enablement. Tell people what is changing, why it is changing, and what they need to do differently. Managers need talking points and FAQs before employees start asking questions.

    Success Metrics

    Payroll accuracy and on-time rate. Track errors per pay period and time to resolution. Best-in-class is 99%+ accuracy with same-day resolution on errors.

    Ticket SLAs and time-to-resolve ER cases. How long does it take to get an answer? How long does it take to close a case? Track both.

    Error rate trends and audit findings. Are errors going down over time? Are audit findings clean? If not, something is broken.

    Choosing the Right Partner, Step by Step

    Choosing a provider is not like choosing a vendor. This is a relationship that touches every employee, every pay period, and every compliance risk you carry. Get it wrong, and you spend the next two years unwinding the damage. Here is how to get it right.

    Scorecard Template

    Requirements. Model fit, entity support, benefits strategy, payroll complexity, security. These are table stakes. If a provider does not meet all of them, they do not make the shortlist.

    Must-haves. Accuracy SLAs, parallel payroll, ACA/COBRA handling, integrations. These are non-negotiable. If they will not commit to SLAs, walk.

    Nice-to-haves. Analytics, org design support, manager training. These are differentiators. If two providers are tied on must-haves, nice-to-haves break the tie.

    Red flags. Wage-base restarts, unclear tax handling, hidden fees, off-menu add-ons. Any of these should disqualify a provider immediately.

    RFP Question Set

    Model fit and exclusions. What is included in the base fee, and what is not? Get it in writing.

    Fee structure and what is not included. PEPM or percent of payroll? Setup fees? Termination fees? COBRA surcharges?

    Escalation path, ER investigations, leaves. How do you escalate a critical issue? Who handles high-risk ER cases? What is the process for complex leave scenarios?

    Compliance posture, SOC reports, breach procedures. How do they handle data security? What happens if there is a breach? Who notifies affected employees?

    Negotiation Watchouts

    Wage-base restarts and timing of transitions. If you switch mid-year to a non-CPEO, you restart the federal payroll tax wage base and pay double taxes for the year. That is a real cost, and it is avoidable if you use a CPEO.

    Hidden fees, COBRA surcharges, and print-mail costs. Get a full cost breakdown, not just the base fee. Some providers charge separately for printing and mailing benefits materials, COBRA notices, or year-end tax forms.

    Off-menu add-ons that bypass SLAs. If you need something custom, make sure it is covered by the same SLAs as the core service. Off-menu work often gets second-tier support.

    Termination, data export, and transition support. What happens if you leave? How do you get your data back? In what format? How much does it cost?

    Why the Philippines Is a Strategic HR Outsourcing Base for U.S. Companies

    Scale and maturity. The Philippines’ IT-BPM sector closed 2024 at 1.82 million jobs and USD 38 billion in revenue, signaling depth, specialization, and resilience. This is not a nascent market. This is an established industry with infrastructure, talent pipelines, and decades of operating history.

    English proficiency and cultural fit. The country ranks #22 globally with High proficiency in EF’s 2024 English Proficiency Index, #2 in Asia, which supports strong communications for U.S. organizations. English is not a second language. It is a working language. That matters when you are running payroll or handling employee relations cases.

    Cost efficiency without cutting capability. Wage arbitrage and deep expertise across shared services, customer operations, IT, and healthcare deliver material savings versus U.S. hiring, especially for operations at scale. You are not trading quality for cost. You are getting both.

    Follow-the-sun coverage. Manila’s time zone enables extended service windows and true 24×7 coverage when paired with U.S. teams. You can run payroll processing overnight, handle employee inquiries around the clock, and maintain service levels that would require shift work in the U.S.

    Risk management. Mature vendors follow data security, payroll, and compliance best practices. Your due diligence should confirm controls, SLAs, and governance, then align them to U.S. policies.

    If you want a predictable build in the Philippines with measurable outcomes, choose a partner built for long-term success, not just placement.

    Making the Call

    If you want pooled benefits leverage and turnkey administration in the U.S., a PEO is often the fastest path. If you have HR leadership and want precision outsourcing with more control, choose HRO. If you need to hire where you lack entities, start with an EOR. In all cases, treat compliance as a shared responsibility, demand clear SLAs, and insist on transparent pricing.

    Next step: Run a structured assessment, then run a short RFP with apples-to-apples pricing and SLAs. If the Philippines is in scope, book a discovery call with Penbrothers to see transparent cost models, role-by-role salary benchmarks, and a Hypercare plan that starts delivering in 90 days.

    Frequently Asked Questions

    1. What is the main difference between a PEO and an EOR?

    The main difference is the legal employment relationship and where they are used. A PEO (Professional Employer Organization) is a co-employer that shares liability with you and is used for your domestic workforce in a country where you already have a legal entity. An EOR (Employer of Record) is the sole legal employer and is used to compliantly hire workers in a foreign country where you do not have a legal entity.

    2. What is the difference between a PEO and an HRO?

    The key difference is the employment model. A PEO is a co-employment relationship where the provider manages most HR functions under one umbrella and files taxes under its own tax ID. An HRO (Human Resources Outsourcing) is a service model where you buy specific, modular services (like just payroll) from a vendor. With an HRO, you remain the sole legal employer and retain all liability.

    3. If I use a PEO or HRO, am I still legally responsible for compliance issues?

    Yes, in most cases. With an HRO, you are 100% legally liable for everything, as you are the sole employer. With a PEO, you are in a co-employment relationship, and while the PEO provides expertise, your company still shares significant legal liability. The only exception is a Certified PEO (CPEO), which can assume sole liability for federal payroll taxes.

    4. How does HR outsourcing save money?

    It saves money in several ways: by reducing the direct costs of in-house HR staff and software; by providing access to cheaper, pooled employee benefits (a major PEO advantage); and by reducing the financial risk of costly compliance penalties and fines related to payroll and labor laws.

    5. What HR functions should a company never outsource?

    You should never outsource the core of your business. This includes functions that define your company’s culture and brand voice, executive compensation strategy, the final decision-making on high-risk employee relations issues and terminations, and the overall strategic workforce plan.
