PEO Pricing Guide
How PEO Fees Are Structured (And Where Brokers Find the Hidden Ones)
PEO pricing has two layers: the visible fee structure you're quoted, and the charges that appear later on invoices. Understanding both before you sign is the difference between an accurate cost comparison and an expensive surprise at renewal.
How PEO Fees Are Actually Built
Before you can spot what's hidden, you need to understand what the visible structure looks like — and why two providers can quote the same headline rate while delivering very different all-in costs.
Model 1: PEPM (Per Employee Per Month)
A flat fee charged per employee regardless of salary. Most common for white-collar, professional service, and tech employers.
Model 2: Percentage of Payroll
A percentage of total gross payroll. Common for hourly workforces, construction, and employers with variable wages.
What's Typically IN the Base Rate vs. What's Excluded
| Service Component | Full-Service PEO (included in base rate) | Add-On / Extra (commonly billed separately) |
|---|---|---|
| Payroll processing | ✓ Yes | — |
| Payroll tax filing | ✓ Yes | — |
| HR advisory support | ✓ Yes | — |
| HRIS/HR technology platform | Often | Sometimes billed as SaaS fee |
| Health insurance premiums | — | Always separate — employer + employee share |
| Benefits admin fee | Sometimes | Commonly $15–$35 PEPM extra |
| Workers' comp premium | — | Always separate — based on class codes |
| EPLI (Employment Practices Liability) | Sometimes | Often excluded or billed separately |
| 401(k) administration | Sometimes | Often extra $5–$20 PEPM |
| ACA reporting (1094/1095) | Often | Some PEOs bill $200–$500/yr |
| COBRA administration | — | Typically $50–$100 per participant/month |
| New hire onboarding processing | Often | Some PEOs charge $25–$150 per hire |
The "headline rate" — the PEPM or percentage-of-payroll figure in a proposal — typically covers payroll and HR administration only. Workers' comp, benefits premiums, and add-on service fees are layered on top. An independent broker will show you all-in cost from day one.
12 Common Hidden PEO Fees
Most of these fees are technically disclosed somewhere in the contract — but they're rarely surfaced during the sales process. An independent broker will flag all of these before you sign.
Benefits Administration Fee
A per-employee monthly charge for administering health benefits — separate from the premium. Can add $15–$35 PEPM to your true cost.
COBRA Administration Fee
Charged per COBRA participant per month for managing continued coverage after termination. Often $50–$100 per participant.
Workers' Comp Policy Fee
An administrative surcharge on top of your actual workers' comp premium. Watch for flat fees or percentage markups on the base premium.
New Hire Onboarding Fee
A per-hire charge for processing new employee paperwork and system setup. Ranges from $25 to $150+ per hire depending on the PEO.
Offboarding / Termination Fee
A charge for processing employee terminations — separate from unemployment claims. Often buried in the contract at $50–$200 per termination.
ACA Compliance Reporting Fee
Annual fee for filing 1094-C and 1095-C forms. Should be included in a full-service PEO — but some charge $200–$500 per year separately.
W-2 and Year-End Processing Fee
Some PEOs charge an annual fee for year-end payroll reconciliation and W-2 distribution, ranging from $150 to $500+.
State Registration Fee
For multi-state employees, PEOs sometimes charge a one-time or annual fee per state to register as an employer. Can be $250–$750 per state.
HR Software / Platform Access Fee
Access to the PEO's HR information system (HRIS) is sometimes billed as a separate SaaS fee rather than included in the service rate.
Renewal Rate Markup
The headline rate quoted during onboarding often increases at renewal with minimal explanation. Ask upfront how renewal pricing is determined.
Mid-Year Benefits Change Fee
Some PEOs charge to process mid-year qualifying life events (marriage, birth, etc.) that change an employee's benefits elections.
Early Termination Fee
If you exit before the contract term, some PEOs charge a penalty. This can be a flat amount or calculated as remaining monthly fees. Always review this clause before signing.
Don't navigate this alone
Knowing what fees exist is the easy part. Getting them removed requires leverage.
These fees exist because PEOs count on employers not knowing to push back. Our brokers work on your behalf — negotiating with providers using the combined leverage of our full client base. That volume is the only real pressure a PEO responds to. Individual employers rarely get these fees removed; clients represented by an experienced broker typically do.
How to Compare True PEO Cost
Never compare PEO providers on headline rate alone. Use this framework to get to an apples-to-apples number.
Ask for an all-in quote
Request a written quote that includes all fees — base service fee, benefits admin, workers' comp markup, onboarding/offboarding, and any software fees. Tell them you want 'all-in PEPM.'
Request itemised pricing
Ask for each line item separately. If a provider can't or won't itemise their pricing, that's a red flag about transparency.
Ask about renewal pricing methodology
Get it in writing: how renewal rates are set, how much notice you'll receive, and whether there's a cap on year-over-year increases.
Have your contract reviewed by a broker
An independent PEO broker will identify hidden fee clauses in the contract and negotiate them out or down — at no cost to you.
Compare total cost, not just service fee
Include benefits premiums, workers' comp, and all admin charges in your comparison. A slightly higher service rate from a provider with no hidden fees is often a better deal.
Suspect you're already paying hidden fees?
If your PEO bill has grown unexpectedly or you've never seen an itemised breakdown, it's worth requesting one. Our brokers can review your current invoices and compare your effective rate against the market — and if switching providers makes sense, we'll manage the whole transition.

How to Protect Yourself From Hidden PEO Fees Before You Sign
The hidden fee problem in PEO pricing exists because most businesses evaluate providers using the information the PEO chooses to put in a proposal — not a complete accounting of what will appear on monthly invoices. Providers know that a higher-than-expected first invoice rarely causes contract cancellation; by then, the switching costs feel too high. Identifying these fees before signing requires asking questions most businesses don't know to ask and reviewing contract exhibit language that most businesses don't read. The PEO pricing guide explains how the full cost picture is constructed layer by layer.
The most impactful hidden costs typically fall into three buckets: service-adjacent fees (COBRA admin, FSA/HSA processing, new hire and offboarding charges), benefits-related charges (premium contribution calculation fees, benefits admin tiers, life event change fees), and compliance-related fees (state registration in new jurisdictions, ACA reporting, multi-state premium calculations). The multi-state compliance checker will show you which additional registrations you'll need — and which PEOs might charge you for managing them. Use the PEO vs in-house cost calculator to model the complete economics including these secondary charges.
The most effective defense is the PEO contract review — specifically the service exhibits and fee schedules attached to the master service agreement. These documents list every billable item. An experienced PEO advisor reviews these exhibits line by line, flags non-standard charges, and negotiates either their removal or a cap. When we represent a client through the proposal process, we request an explicit "no hidden fees" certification from each provider and compare the exhibit language across all proposals to identify where each provider is quietly hiding margin.
For small businesses, the per-employee impact of hidden fees is higher because fixed charges (like COBRA administration flat fees or state registration costs) don't scale with headcount. The best PEOs for small business tend to have simpler fee structures — but even the best providers have some charges buried in their exhibits. For first-time PEO buyers specifically, the PEO explainer is a useful foundation before reviewing any proposal. The employee benefits cost layer is where the biggest pricing surprises tend to hide.
If you're already with a PEO and have noticed invoice creep — charges that weren't in the original proposal — it's worth benchmarking your actual spend against the market. The guide to switching PEO providers covers when switching makes financial sense. The PEO exit checklist covers the mechanics. Use our PEO evaluation framework to score your current provider against alternatives on cost transparency specifically. Take the HR compliance quiz to assess any compliance exposure. Your workers' compensation cost is another area where markup can be obscured and is worth a separate review. Book a free consultation to have our team audit your current PEO invoices and identify where you may be overcharged. Take the PEO Fit Check to get a quick readiness assessment.
The renewal pricing trap is closely related to the hidden fee problem. Many PEO contracts specify that renewal rates are set at the provider's discretion or "at market rates" — language that effectively gives the provider unlimited ability to increase your cost year over year. We've seen clients whose all-in cost increased 22% between year one and year two, with the increase distributed across the admin fee, the benefits admin component, and several smaller line items that each appeared reasonable in isolation. The cumulative effect was material. The solution is to negotiate annual increase caps — typically 3–5% — into the original contract before you sign. This is a negotiating point that's available before signing and essentially unavailable after. When we represent clients through the proposal process, rate cap language is one of three non-negotiable asks we make of every provider. It's one of the most financially significant concessions available, and most providers will agree to it when asked by a broker with sufficient placement volume. Review the full PEO contract review guide to see what other protections are negotiable before you sign.
