"Fractional HR" is a term that gets used a lot and explained rarely. If you have heard it from a peer, a CPA or a search result, here is what it actually means, what it does not mean, and how to tell whether your company is ready for it.
The definition
Fractional HR is a senior HR professional who works with your company for a fraction of their time, on an ongoing basis, instead of joining as a full-time employee. Think of it the same way you think of a fractional CFO: you get the experience and judgment of someone who has run the function before, sized to what a company of your size can use and afford.
The word "fractional" describes the time, not the quality. A good fractional HR leader has done the full-time job, usually for years, and brings that experience to several companies at once.
What it is not
It helps to be clear about the things fractional HR is often confused with.
It is not a PEO. A professional employer organization becomes the co-employer of your staff, runs payroll and benefits, and provides HR support through a call center or a portal. You pay per employee. Fractional HR is a person, not a platform; you keep your own payroll and benefits.
It is not HR software. Software handles the transactional pieces: onboarding forms, PTO tracking, document storage. It does not tell you whether to terminate someone, how to handle a harassment complaint, or whether your new pay plan violates Florida law.
It is not a one-time project. A handbook, a compliance audit or a training session is project work. Fractional HR is the ongoing relationship that comes after, or alongside, those projects.
What a fractional HR engagement looks like
Every engagement is shaped to the company, but most of mine follow a similar pattern.
Month one: assessment
I review what exists: policies, personnel files, pay practices, job classifications, postings, onboarding and offboarding. You get a prioritized list of what is fine, what needs fixing and what is urgent. For most small companies the urgent list is short but real: an exempt classification that should be non-exempt, a missing I-9 process, or a handbook that predates three changes in the law.
Months two and three: fix the foundation
We work through the list. That usually means a current handbook, clean job descriptions, a pay and classification review, and a simple process for discipline and documentation that your managers can actually follow.
Ongoing: be the HR department
After the foundation is in place, the retainer covers the things a company needs HR for every month:
- A standing point of contact for you and your managers when a people question comes up
- Hiring support, from job postings to offer letters to onboarding
- Employee relations: complaints, performance problems, terminations, and the conversations nobody wants to have
- Compliance monitoring as federal, Florida and county rules change
- Manager coaching so the same problems stop landing on your desk
- A quarterly review so HR work is planned instead of reactive
What it costs compared with the alternatives
I will not fabricate a market rate here because it varies with hours and scope, but the comparison itself is straightforward.
| Option | What you get | Rough cost structure |
|---|---|---|
| Full-time HR manager | One person, 40 hours a week, one level of experience | Salary plus benefits and payroll taxes |
| PEO | Payroll, benefits, basic HR through a platform | Per-employee monthly fee, plus loss of control over benefits and vendors |
| Fractional HR | Senior HR leader, set hours per month, your own payroll and benefits | Monthly retainer, a fraction of a full-time salary |
| Nothing | The owner or office manager does HR on the side | Free until the first claim, audit or bad termination |
For companies under about 75 employees, a full-time HR manager is usually more than the company needs and often less experienced than a fractional leader. A PEO can make sense for very small companies that mainly want benefits access, but I have moved a client off a PEO to in-house payroll and benefits and saved them more than $38,000 a year, so the bundle is not automatically the cheaper option.
When you are big enough
There is no magic number, but there are signals.
Around 15 to 20 employees. At 15, federal anti-discrimination laws (Title VII, the ADA) start applying. At 20, the ADEA. Somewhere in that range the owner stops being able to know every employee well enough to manage them informally.
At 25 employees in Florida. E-Verify becomes mandatory for private employers. It is a small thing, but it is the kind of small thing companies miss when nobody owns HR.
When you add a management layer. The first time you promote someone to manage other people, you need documentation habits, a discipline process and someone those managers can call.
When something has already gone wrong. A complaint, a wage claim, a termination that turned into a demand letter. Most companies call after the first one. The second one is the expensive one.
When you have grant funding or a board. Nonprofits often need HR earlier than their headcount suggests, because funders and boards expect written policies and clean files.
How to choose a fractional HR provider
A few questions worth asking anyone you talk to, including me:
- Have you run HR inside a company, or only advised from outside? Both matter, but the first one matters more when a real situation lands.
- Will I work with you, or with whoever is available? Consistency is the whole value of fractional HR.
- Do you know Florida? State and county rules differ, and generic advice is how small businesses get hurt.
- What happens when I need more hours in a bad month? You want a clear answer, not a surprise invoice.
- Can I start with a project and grow into a retainer? A compliance review is a low-risk way to find out whether you work well together.
The bottom line
Fractional HR is the way a company of 15 to 100 people gets a senior HR leader without paying for a full-time one. If that sounds like where you are, my HR outsourcing and fractional HR service explains exactly how I work, and the first conversation is free.
