What Is a Fractional HR, and How They Support Your Business

Growing companies face a common challenge: they need HR expertise but can't justify a full-time HR hire. Founders end up spending hours on employee handbooks, compliance questions, and performance management issues instead of building the business.

Fractional HR offers a solution. Senior-level human resources leadership at a fraction of the cost of a full-time hire. You get experienced HR professionals who understand your business needs without the $150K+ annual investment in a dedicated HR department.

‍

What Is Fractional HR?

Fractional HR is part-time, senior-level HR leadership provided by experienced HR professionals on a contracted basis. Rather than hiring a full-time HR manager or director, companies engage a fractional HR consultant for a set number of hours per week or month, getting access to high-level expertise without the full-time commitment.

The "fractional" model means you get a fraction of their time and cost while accessing their full HR expertise. These aren't junior generalists learning on the job. Fractional HR professionals typically bring 10-20+ years of experience as HR directors, VPs, or CHROs at established companies.

Fractional human resources focuses on strategic work that shapes how your company manages people: building HR processes, ensuring HR compliance, developing policies, advising on employee relations, and creating performance management frameworks. This differs from day-to-day transactional tasks like payroll processing or benefits administration, which are better suited to outsourced HR providers.

Typical engagement structures include monthly retainers (set hours per month), project-based work (specific initiatives like handbook development), or hybrid models combining ongoing support with project capacity.

Fractional HR vs. Outsourced HR vs. Full-Time HR

Understanding where fractional HR fits among your options helps determine the right solution for your specific needs.

Fractional HR

Fractional HR provides senior HR expertise on a part-time basis with strategic focus. You get a dedicated HR professional who becomes embedded in your company culture, attending leadership meetings, understanding your team members, and providing ongoing strategic guidance. The relationship is consultative: they're your HR business partner, just not full-time.

Best for: Companies needing HR leadership and expertise without full-time cost; businesses building HR infrastructure; organizations in growth phases needing experienced guidance on HR strategy.

Outsourced HR (HRO)

Outsourced HR means contracting with a company to handle specific HR functions like payroll processing, benefits administration, and compliance paperwork. It's transactional and process-focused rather than strategic. You might work with shared service teams rather than a dedicated professional who knows your business.

Best for: Companies needing HR tasks handled efficiently; organizations wanting to offload administrative burden without strategic guidance.

Full-Time HR

The traditional model: hiring an in-house HR professional as a full-time employee. Provides dedicated focus and deep company knowledge but comes with full salary, employee benefits, and overhead costs, typically $120,000-180,000+ annually for an experienced HR manager or director.

Best for: Companies with sufficient HR volume and budget to justify full-time role; organizations where HR complexity requires daily dedicated attention.

PEO (Professional Employer Organization)

A co-employment model providing HR services, access to better benefits packages, and compliance support. The PEO becomes employer of record for certain purposes, which is a different structure than fractional HR's consulting relationship.

Best for: Small businesses wanting access to enterprise-grade benefits through co-employment structure.

Benefits of Fractional HR

Cost Savings

The economics are straightforward: access senior HR expertise at a fraction of the cost of a full-time hire. A fractional HR engagement might cost $3,000-6,000 monthly versus $150,000-200,000+ annually for a full-time HR leader with benefits.

For startups and small businesses, this means strategic HR guidance without the investment that only makes sense at larger scale. You're paying for expertise when you need it, not maintaining overhead during slower periods.

Senior-Level Expertise

Fractional HR professionals are typically former HR directors, VPs, or CHROs with years of experience across multiple companies and industries. They bring pattern recognition from seeing what works, and what doesn't, across different organizations.

This expertise matters for how to build the ultimate interview process, developing compensation frameworks, navigating difficult terminations, or building scalable HR operations. Junior HR hires learn these skills over years; fractional HR experts bring them day one.

Flexibility and Scalability

Fractional arrangements scale with business needs. Increase hours during growth phases, talent acquisition pushes, or organizational changes. Scale back during stable periods. No long-term employment commitment means your HR support adjusts to actual requirements rather than fixed headcount.

This scalable model works particularly well for companies with variable HR needs, including seasonal businesses, project-based organizations, or startups navigating rapid growth followed by consolidation periods.

Objective Outside Perspective

Fractional HR professionals bring fresh eyes to your organization. They're not caught up in internal politics or "how we've always done things." They can provide honest assessments of what's working, benchmark your practices against industry standards, and recommend changes that internal team members might hesitate to suggest.

This broader perspective proves valuable when addressing company culture issues, restructuring teams, or evaluating whether HR processes serve business goals effectively.

Address Specific HR Challenges

Fractional HR can target specific needs: building performance management systems, creating employee handbooks, developing job descriptions, establishing talent retention strategies, or preparing for rapid hiring. You deploy expertise where it's needed most rather than maintaining generalist coverage across all HR functions.

Bridge to Full-Time

Fractional HR often serves as a bridge, helping companies build HR infrastructure until they're ready for a full-time hire. A fractional HR leader can establish processes, implement HR technology, and eventually help recruit and onboard their full-time replacement when the organization reaches appropriate scale.

Types of Fractional HR Providers

Fractional HR Consultant

Independent HR consultants work with multiple clients simultaneously. These are typically experienced HR generalists who provide broad HR support across compliance, employee relations, policy development, and strategic planning. Engagements tend to be flexible and personalized to each client's needs.

Fractional CHRO

Fractional Chief Human Resources Officer services provide C-suite level HR leadership for companies needing executive-level people strategy without a full-time CHRO. This typically suits larger small businesses or mid-market companies needing board-level guidance, organizational development expertise, and strategic HR initiatives.

Fractional HR Director/Manager

The most common entry point: experienced HR professionals providing hands-on HR leadership without executive scope. Focus areas include building systems, managing employee relations, ensuring HR compliance, and handling the high-level HR needs that founders shouldn't manage themselves. This role bridges the gap between no dedicated HR and full HR department.

Fractional HR Firms

Companies like Bambee, Castle HR, and People Spark provide fractional HR services with team support. Clients get an assigned HR professional backed by broader firm resources, offering more coverage and continuity than solo consultants while maintaining the personalized relationship fractional HR requires.

What Are the Costs of Fractional HR?

Typical Pricing Models

Monthly retainer: Set hours per month for ongoing support. Most common structure for fractional HR relationships.

Hourly rate: Pay for time used. Works for lighter-touch support or companies with variable needs.

Project-based: Fixed fee for specific initiatives like handbook development, compensation study, or compliance audit.

Typical Cost Ranges

Fractional HR Manager/Director: $2,000-6,000/month for 10-20 hours monthly; $100-200/hour for on-demand work.

Fractional CHRO: $5,000-15,000/month for strategic leadership; $200-400/hour.

Project work: $5,000-25,000+ depending on scope and complexity.

For context: a fractional engagement at $5,000/month ($60,000 annually) provides senior HR expertise at roughly 40-50% the cost of a full-time HR director ($120,000+ salary plus 25-30% benefits overhead).

Factors Affecting Cost

Pricing varies based on provider experience level, hours required, complexity of HR needs, geographic market, and whether you engage an independent consultant or firm. More experienced fractional HR professionals command higher rates but often deliver faster results.

How to Choose a Fractional HR Provider

Assess Your HR Needs

Start by identifying what you actually need. Strategic guidance? Compliance cleanup? Performance management systems? Day-to-day HR support? Understanding your specific needs determines whether fractional HR fits and what type of provider works best.

Evaluate Experience and Fit

Look for relevant experience: industry knowledge, company-stage experience (startup vs. established), and functional expertise matching your needs. A fractional HR consultant who's built HR operations at remote first companies brings different value than one focused on manufacturing environments.

Cultural fit matters too since this person represents HR to your team.

Understand the Engagement Model

Clarify expectations: How many hours monthly? How accessible between scheduled times? What's included versus additional cost? How do they communicate? Ensure the model matches how you work.

Check References

Speak with other clients, particularly similar-sized companies. Ask about responsiveness, quality of strategic guidance, and whether they'd engage again.

Start With Defined Scope

Consider starting with a specific project or trial period before committing to long-term retainer. This allows both sides to evaluate fit before deeper commitment.

When Should You Consider Fractional HR?

Signs fractional HR makes sense:

• 15-150 employees and growing
• Founders spending significant time on HR tasks
• Compliance concerns keeping leadership up at night
• Need for HR infrastructure but not full-time HR head
• Facing specific HR challenges requiring expertise
• Planning significant growth or organizational change

Signs you might need a different solution:

• Primary need is transactional (payroll, benefits enrollment), so consider HR outsourcing
• Company large enough to justify full-time HR leader (150+ employees typically)
• Need co-employment structure for benefits access, so consider PEO
• Very early stage with minimal HR needs, may not need formal HR support yet

FAQs

What is fractional HR?

Fractional HR is part-time, senior-level HR leadership from experienced HR professionals on a contracted basis. They focus on strategic work like building HR infrastructure, ensuring compliance, developing policies, and advising on employee relations rather than transactional tasks. Typically serves companies with 15-150 employees needing HR expertise without full-time cost.

How much does fractional HR cost?

Typically $2,000-8,000/month for ongoing retainers. Hourly rates range from $100-250 for experienced HR directors to $200-400 for CHRO-level professionals. Project work runs $5,000-25,000+ depending on scope. This represents roughly 40-60% less than equivalent full-time salary and benefits.

What is the difference between fractional HR and outsourced HR?

Fractional HR provides senior-level leadership and strategic guidance from a dedicated professional embedded in your company. Outsourced HR handles transactional HR functions (payroll, benefits administration) through service providers focused on process execution. Fractional HR is about expertise and leadership; outsourced HR is about task efficiency.

Is it cheaper to outsource HR?

Depends on your needs. Outsourcing transactional tasks is typically cost-effective for small businesses. Fractional HR costs 40-60% less than full-time senior HR hire while providing strategic expertise. However, the cheapest option isn't always best since underinvesting in HR creates costs through compliance issues, poor retention, and founder time consumed by HR problems.

What is the difference between fractional HR and PEO?

Fractional HR is a consulting relationship where you remain the sole employer while getting HR expertise and strategic guidance. PEO is a co-employment arrangement where the PEO becomes an employer of record for tax and benefits purposes, providing comprehensive services plus benefits access. Fractional HR is flexible and strategic; PEO is structured and administrative. Some companies use both.
