Is fractional HR cheaper than a PEO?

They price differently, so it depends on your headcount. Fractional HR is a flat monthly retainer, starting around $1,800/month regardless of headcount. A PEO charges per employee per month, often $100 to $200 per employee, or a percentage of payroll, so PEO cost scales directly with your team size. For a 30-person company, fractional HR is usually the lower and more predictable cost; a PEO may bundle in benefits and workers' comp that have their own value.

Does fractional HR include payroll and benefits like a PEO?

Not in the same way. A PEO becomes a co-employer and runs payroll, sponsors benefits, and assumes certain liabilities under its own tax IDs. Fractional HR coordinates and administers your payroll and benefits through your own providers (Gusto, Rippling, a broker) without co-employment. You keep full control of your company and your employee relationships.

What is co-employment and do I want it?

Co-employment means the PEO becomes a joint legal employer of your staff, sharing certain responsibilities and liabilities. It can simplify benefits and compliance, but it also means your employees are technically on the PEO's books, and leaving a PEO later means migrating everyone off their systems. Fractional HR involves no co-employment: your people are entirely yours.

When does a PEO make more sense than fractional HR?

A PEO is often the better fit if you want richer benefits than you could buy alone (PEOs pool many small companies to negotiate plans), if you want to offload payroll-tax and workers' comp liability, or if you have no interest in keeping any HR in-house. Fractional HR fits better if you want to keep control, you already have decent benefits, and you want senior judgment on the hard people problems without co-employment.

Can I switch from a PEO to fractional HR later?

Yes, and many growing companies do, usually once they are large enough that the PEO's per-employee fees exceed the cost of running HR themselves. The migration takes planning (moving payroll, benefits, and records off the PEO), which is exactly the kind of transition a fractional HR partner can manage for you.

Fractional HR vs. PEO: Which Is Right for Your Business?

Almost every small business shopping for HR help runs into the same fork in the road: a PEO (professional employer organization) or a fractional HR partner. The marketing for both sounds similar, which is why founders end up confused. The truth is they are different models that solve different problems, and the right choice depends on what you actually want to keep control of.

This is a straight comparison. Bevel HR is a fractional HR firm, so we have a side, but we will tell you plainly where a PEO is the better answer, because sending you toward the wrong model helps no one.

The core difference in one sentence

A PEO becomes a co-employer of your staff and takes over payroll, benefits, and certain liabilities under its own systems. Fractional HR runs your people function as an outside expert without co-employment, leaving your company, your payroll, and your employees entirely yours.

The simplest way to decide: do you want to offload employment itself (PEO), or do you want senior expertise running the HR you still own (fractional HR)? That single question resolves most of the decision.

Side-by-side comparison

Factor	Fractional HR	PEO
Pricing model	Flat monthly retainer, from ~$1,800/mo	Per employee per month, or % of payroll
Co-employment	No, you stay the sole employer	Yes, PEO is a joint employer
Payroll	Coordinated through your own provider	Run on the PEO's system
Benefits	Your own plans or broker	PEO's pooled plans (often richer)
Control of employees	Fully yours	Shared with the PEO
Senior HR judgment	Direct access to a senior practitioner	Usually a service team or call center
Compliance & risk	Advised and managed; liability stays with you	Some liability assumed by PEO
Best for	10 to 75 employees keeping control	Companies offloading employment entirely

Where a PEO genuinely wins

We will say it clearly: there are real situations where a PEO is the smarter choice.

You want benefits you could not buy alone. PEOs pool hundreds of small companies to negotiate health plans, which can mean better coverage at a better rate than a 20-person company could get on its own.
You want to offload liability. A PEO assumes responsibility for certain payroll-tax and workers' comp obligations under its own IDs.
You want zero HR in-house, ever. If your goal is to never think about employment mechanics again, the PEO model is built for that.

Where fractional HR wins

You want to keep control. No co-employment means your people, your payroll, and your culture stay entirely yours. Nothing to untangle later.
You want senior judgment, not a call center. Fractional HR gives you direct access to an experienced practitioner who handles your hardest problems personally, rather than a ticketing queue.
You want predictable, flat cost. A retainer does not balloon as you hire. A PEO's per-employee fee grows with every headcount.
You already have decent benefits and do not need the PEO's pooled plans to justify the per-employee cost.

The cost comparison, honestly

For a company around 30 employees, a PEO at roughly $125 per employee per month runs about $45,000 per year in administrative fees, separate from the benefits themselves. Fractional HR at the Growth tier runs $3,500 per month, about $42,000 per year, flat, no matter how many people you add within the band. The numbers are closer than the marketing suggests, which is why the decision should turn on control and benefits, not just price. (We break down the full-time-hire comparison in fractional vs full-time HR cost.)

How to choose, step by step

Map what you actually need: just compliance and the hard conversations, or full employment offload including benefits and liability?
Price both against your real headcount, remembering the PEO fee scales and the retainer does not.
Decide how much control you want to keep. If keeping your employees fully yours matters, that points to fractional.
Check the benefits math. If you cannot get good group plans alone, the PEO's pooling may justify its fee on its own.
Plan for the exit. Leaving a PEO later means a migration; fractional HR has no lock-in.

The bottom line

A PEO offloads employment. Fractional HR runs the HR you keep. For a company in the 10 to 75 employee range that wants senior expertise without giving up control of its people, fractional HR is usually the better fit, but if pooled benefits or full liability offload are your priority, a PEO earns its fee. The wrong move is choosing on price alone, because they are close enough that fit should decide.
