At 25 employees, you’re stuck in an awkward insurance no-man’s-land. You’re too big to qualify for the cheapest small-group plans, but nowhere near large enough to have real leverage with carriers. When renewal season comes around, you’re essentially price-takers — and carriers know it.
This is exactly where a PEO changes the math. By pooling your 25 employees into a much larger group, a PEO gives you access to insurance rates and plan options that are simply out of reach at your size independently. But the value isn’t automatic, and not every PEO handles insurance the same way.
Some PEOs lock you into a master plan with little flexibility. Others give you more choice but less pricing advantage. Some don’t surface the portability risk until you’re trying to leave. The difference between a PEO that genuinely improves your insurance situation and one that just shuffles costs around comes down to how you evaluate the relationship before you sign anything.
These seven strategies are built specifically for the 25-employee decision. Not generic PEO advice — the specific tradeoffs, mechanics, and questions that matter at this headcount, where the cost implications are real and the stakes are high enough to get it right.
1. Understand How PEO Group Insurance Purchasing Actually Works at Your Size
The Challenge It Solves
Most business owners know PEOs offer “better rates” on insurance, but few understand why — or why it matters more at 25 employees than at 100. Without understanding the mechanics, you can’t evaluate whether a specific PEO’s model actually delivers the benefit it’s promising.
The Strategy Explained
Here’s the core dynamic: small-group insurance pricing is heavily influenced by the claims experience of your specific pool. At 25 employees, one or two high-cost individuals can materially shift your renewal rate. You’re essentially self-insuring your own risk in a very small pond.
A PEO pools your employees with thousands of others across its client base. Your 25 people become part of a group that might be 50,000 or 100,000 strong. Carriers price that risk very differently. The volatility that makes small-group insurance unpredictable largely disappears when you’re a rounding error in a massive pool.
There are two main models to understand. The master health plan model means the PEO acts as the plan sponsor — all client employees are on one large group plan. You get the best pooled rates, but plan customization is limited. The multi-carrier model means the PEO offers access to several carriers while still leveraging group purchasing. More flexibility, but sometimes less pricing advantage. Neither is universally better; it depends on your team’s needs and your priorities.
Implementation Steps
1. Ask every PEO you’re evaluating whether they operate a master plan, a multi-carrier model, or both — and get specifics on which carriers are involved.
2. Ask how many total covered lives are in their group purchasing pool. Size matters here. A PEO with 10,000 employees in its pool has less leverage than one with 100,000+.
3. Ask directly: does your group experience affect my renewal pricing, or am I fully pooled? The answer tells you how much of the volatility risk you’ve actually transferred.
Pro Tips
Don’t assume bigger PEO always means better insurance rates. The quality of their carrier relationships and how they’ve structured their master plan matters as much as raw headcount. A well-negotiated plan with a mid-size PEO can outperform a loosely structured plan from a larger one. If you’re still deciding whether a PEO makes sense at this headcount at all, the broader guide on PEO for 25 employees covers the full picture beyond just insurance.
2. Build Your True Cost Baseline Before You Compare Anything
The Challenge It Solves
You can’t evaluate a PEO’s insurance value without knowing what you’re actually paying today. Most business owners know their monthly premium — but that’s only part of the picture. Without a complete baseline, you’ll be comparing apples to a number you made up.
The Strategy Explained
Your real insurance cost includes more than the premium line on your invoice. It includes your employer contribution, employee contribution, the time your HR person (or you) spends managing open enrollment and carrier questions, renewal negotiation friction, and any gaps in coverage that create downstream costs.
At 25 employees, the admin burden is often underestimated. You’re large enough that benefits administration is a real job, but small enough that you probably don’t have a dedicated benefits person. That time has a cost, even if it doesn’t show up on a spreadsheet.
The right comparison metric isn’t premium vs. premium. It’s total cost of benefits administration — what you pay, what your employees pay, and what it costs operationally to run the program — versus what the PEO’s all-in model costs including their admin fee allocation for benefits.
Implementation Steps
1. Pull your last 12 months of total employer premium payments across all lines — medical, dental, vision, life, disability.
2. Estimate the hours per month spent on benefits administration (enrollment, employee questions, carrier issues, renewal prep) and assign a dollar value based on whoever is doing that work.
3. Note your last renewal increase and whether you had any leverage to push back. That renewal trajectory is part of your baseline too.
4. Document your current plan details: deductible, out-of-pocket max, network type, and any ancillary benefits. You’ll need this to do a real quality comparison later.
Pro Tips
If your renewal has increased significantly in recent years with no real ability to negotiate, that volatility itself is a cost. PEO pooling doesn’t just lower your rate — it stabilizes it. That stability has real value for budgeting and planning at a 25-person company. Companies at adjacent headcounts face similar dynamics — the PEO evaluation framework for 20-person teams offers useful context on where the cost math typically shifts.
3. Evaluate Plan Quality and Depth, Not Just the Premium Number
The Challenge It Solves
A cheaper premium on a thin plan isn’t a win — it’s a tradeoff you might regret at the next open enrollment when employees start asking why their coverage got worse. At 25 employees, your team has diverse needs, and plan quality affects both retention and recruiting.
The Strategy Explained
When PEOs present their insurance options, the headline number is usually the employer premium contribution. That’s the easy comparison. The harder — and more important — comparison is plan design quality: deductible levels, out-of-pocket maximums, network breadth, prescription coverage, and whether the plan actually serves your employee population well.
Ancillary benefits matter more than most employers realize at this headcount. Dental, vision, life insurance, short-term disability, and voluntary benefits like pet insurance or legal coverage are often bundled into PEO plans at group rates that are genuinely difficult to replicate independently. These benefits cost you relatively little to offer but carry real perceived value for employees.
Network adequacy is another area to scrutinize. A plan that looks great on paper but has a narrow network in your geographic area creates friction for employees — and friction creates complaints. Ask for the carrier name and plan type upfront so you can check network coverage in your area before you commit.
Implementation Steps
1. Request full plan documents or Summary of Benefits and Coverage (SBC) for every plan option the PEO offers — not just a summary slide in a proposal deck.
2. Compare deductibles, out-of-pocket maximums, and co-pay structures against your current plan. A lower premium with a dramatically higher deductible may cost your employees more overall.
3. Check the carrier and network type (HMO, PPO, HDHP) and verify network coverage in your primary operating location.
4. Ask what ancillary benefits are included in the base offering versus what requires additional election and cost.
Pro Tips
Pay attention to how many plan options the PEO offers your employees. A single plan with no choice creates frustration, especially for a team with varying family situations. Two or three well-designed options at different price points typically work better than one “average” plan for everyone. Manufacturing companies navigating similar plan quality decisions have found that using a PEO to control insurance costs requires the same scrutiny of plan depth, not just headline premiums.
4. Ask the Right Questions About Workers’ Comp Coverage
The Challenge It Solves
Workers’ comp is often the clearest and most immediate financial win inside a PEO at this headcount — but it comes with mechanics that many business owners don’t fully understand. Getting this wrong can create problems when you eventually exit the PEO relationship.
The Strategy Explained
The operational benefit most people talk about first is pay-as-you-go workers’ comp. Instead of paying a large annual premium upfront based on estimated payroll, you pay per payroll cycle based on actual wages. For a 25-person company managing cash flow carefully, this is a genuine improvement over the traditional model.
What gets less attention is the experience modifier (e-mod) question. Your e-mod is a multiplier applied to your workers’ comp base rate based on your claims history — a better safety record means a lower e-mod and lower premiums. Inside a PEO, the picture gets complicated. Some PEOs use their own aggregate e-mod across all clients. Others track experience at the client level. This distinction matters enormously if you ever plan to leave the PEO, because your e-mod history may or may not transfer with you.
Industry classification codes still apply inside a PEO. If you’re in construction, manufacturing, or another higher-risk category, you won’t simply get generic low rates. But pooling typically softens the pricing impact compared to what you’d pay independently at 25 employees. If your business carries a high experience modifier going into this decision, it’s worth reading specifically about how PEOs handle high insurance mod rates before you assume co-employment will automatically help.
Implementation Steps
1. Ask each PEO whether they use their own aggregate e-mod or maintain client-level experience tracking.
2. If you have a favorable e-mod currently, ask explicitly how entering the PEO affects it — and what happens to it if you leave after two or three years.
3. Confirm your industry classification codes will be applied correctly inside the PEO. Misclassification can create audit liability.
4. Compare the total workers’ comp cost (rate times payroll) under the PEO versus your current policy, accounting for the cash flow benefit of pay-as-you-go.
Pro Tips
If your current e-mod is significantly below 1.0 due to a strong safety record, entering a PEO’s aggregate pool could actually increase your effective rate. This is a scenario worth modeling before you commit. It’s not common, but it happens — and it’s rarely mentioned in the sales process.
5. Understand the Insurance Portability Problem Before You Sign
The Challenge It Solves
This is one of the least-discussed risks in PEO insurance relationships, and it tends to surface at the worst possible time: when you’re trying to leave. Understanding it upfront gives you the ability to negotiate protections before you’re locked in.
The Strategy Explained
When you join a PEO’s master health plan, you typically stop being the plan sponsor. The PEO is. Your employees’ claims history accumulates under the PEO’s group, not yours. After two or three years on the PEO’s plan, you may have no independent claims history to present to a carrier when you try to obtain standalone coverage.
Carriers use claims history to underwrite group health plans. Without it, you’re essentially a new group — and new groups often get less favorable pricing, especially if any of your employees have had significant health events during the PEO years. This doesn’t mean leaving a PEO is impossible, but it does mean the transition can be more expensive and more complicated than you anticipated when you signed.
Some PEOs offer transition assistance or portable plan structures as a negotiation point. Others don’t. Some will provide a letter of experience or work with carriers to facilitate a transition. Knowing what your PEO offers here before you sign is significantly better than discovering the limitation when you’re already trying to exit. A practical guide on how to switch to a PEO covers the transition mechanics in detail, including what to negotiate upfront.
Implementation Steps
1. Ask directly: if we leave your PEO after three years, what claims history documentation can you provide to help us obtain standalone insurance?
2. Ask whether they offer any transition assistance programs or carrier introductions for departing clients.
3. Review the contract language around insurance termination timelines — how much notice is required, and what coverage continuity exists during the transition period?
4. Consider whether a carved-out insurance arrangement (maintaining your own coverage separate from the PEO) is available and whether the cost tradeoff is worth the portability protection.
Pro Tips
Carved-out insurance preserves your independent claims history but typically means you don’t get the PEO’s pooled rates on health. For some companies, the portability protection is worth that tradeoff. For others, the savings are too significant to pass up. There’s no universal right answer — it depends on how long you expect to stay with the PEO and how important transition flexibility is to your planning.
6. Use PEO Benefits as a Recruiting Advantage — With the Right Framing
The Challenge It Solves
At 25 employees, you’re often competing for talent against companies with two or three times your headcount. Access to large-group-quality benefits through a PEO is a genuine differentiator — but only if you communicate it correctly and understand the distinction between what the PEO makes available and what you actually fund.
The Strategy Explained
The PEO gives you access to benefit options that most 25-person companies can’t offer independently. That’s real. But what you elect to fund is still your decision. You control your employer contribution strategy — how much of the premium you cover versus what employees pay. A PEO doesn’t automatically make your benefits generous; it makes quality options available at better rates. Generosity is still your call.
For recruiting purposes, the most compelling message isn’t “we use a PEO.” It’s “we offer the same caliber of health benefits as companies much larger than us.” That framing resonates with candidates who’ve experienced the difference between a thin small-group plan and a well-structured large-group option. Companies that grow to 40 employees face the same recruiting dynamic — the analysis of PEO value at 40 employees shows how benefit quality continues to drive talent decisions as headcount grows.
Voluntary benefits are an underused lever here. Many PEOs include access to voluntary benefits — pet insurance, legal plans, identity theft protection, supplemental life — at group rates with zero employer cost. These benefits cost you nothing to offer but add genuine perceived value to your total compensation package. At 25 employees, that matters.
Implementation Steps
1. Review the full benefit catalog your PEO makes available, including voluntary options, and identify which ones your employee population would actually value.
2. Develop a simple total compensation summary that includes the employer’s health contribution as a dollar value — candidates often don’t realize how much employers are contributing until it’s made explicit.
3. Train whoever handles recruiting on how to explain the benefit quality accurately: carrier name, plan type, and how it compares to what candidates might have at a larger employer.
4. Offer voluntary benefits even if take-up is low initially. The availability itself signals that you take employee well-being seriously.
Pro Tips
Be careful not to over-promise during recruiting. If you’re offering the minimum plan tier to control costs, don’t position it as premium coverage. Candidates who feel misled about benefits become disengaged employees quickly. Be accurate, and let the genuine advantages speak for themselves.
7. Compare Multiple PEOs Side-by-Side on Insurance Before You Commit
The Challenge It Solves
PEO proposals bundle insurance costs with administrative fees in ways that make direct comparison genuinely difficult. Without a structured comparison framework, you’re likely to evaluate based on the number that’s easiest to see — which is usually not the most important one.
The Strategy Explained
Insurance structure varies significantly between PEO providers. One PEO might offer a master plan with excellent pooled rates and limited plan choice. Another might offer multi-carrier flexibility with slightly higher pricing. A third might carve out workers’ comp differently than the others. These aren’t minor variations — they represent materially different cost and risk profiles for your company.
The comparison dimensions that matter most for a 25-person company evaluating insurance are: carrier identity and network quality, number and variety of plan options, how the employer contribution is structured relative to the PEO’s admin fee, workers’ comp model and e-mod handling, and what transition support exists if you eventually leave.
Red flags to watch for in proposals: vague carrier information (“we work with major carriers”), no access to plan documents before signing, inability to see plan design details upfront, and proposals that bundle insurance and admin fees so tightly that you can’t identify what you’re paying for each. Any PEO that resists transparency on these points before you sign should be treated with skepticism. If you’re also evaluating whether a CPEO designation changes the calculus, the CPEO vs. PEO comparison breaks down the decision factors that actually matter.
Implementation Steps
1. Request proposals from at least three PEOs and ask each to provide the same information: carrier name, plan types offered, employer vs. employee premium split, workers’ comp model, and total admin fee structure.
2. Build a comparison matrix that separates insurance costs from administrative fees so you can evaluate each component independently.
3. Ask each PEO to provide full plan documents or SBCs before you sign — not after. Any resistance here is a red flag.
4. Run the total cost model: current insurance + current admin burden vs. PEO all-in cost for equivalent or better coverage. That’s the comparison that matters.
5. Check references specifically from clients at similar headcount who can speak to the insurance experience, not just the general PEO relationship.
Pro Tips
Watch for proposals that lead with the insurance savings and bury the admin fee. The right question is always total cost, not just premium cost. A PEO that saves you $200 per employee per month on health insurance but charges $300 per employee in admin fees hasn’t actually saved you anything. Do the full math before you get excited about any single number.
Putting It All Together
At 25 employees, the insurance argument for a PEO is often the most compelling one on the table. The math genuinely works in your favor: pooled purchasing power removes the volatility that makes small-group insurance unpredictable, pay-as-you-go workers’ comp improves cash flow, and access to plan options you couldn’t get independently is a real recruiting advantage.
But the value isn’t automatic. It depends on which PEO you choose, which plans you elect, and whether you’ve done the baseline work to know what you’re actually comparing against.
If you’re working through this decision, the order of operations matters. Start with your current cost baseline so you have something real to compare against. Understand how the PEO’s pooling model actually works. Dig into plan quality, not just premium price. Ask the workers’ comp questions that most salespeople won’t volunteer answers to. And make sure you understand the portability implications before you sign anything.
Then compare at least three providers side-by-side with real data — full plan documents, separated fee structures, and honest answers about what happens if you eventually leave.
If you want a faster path to that comparison, PEO Metrics provides unbiased, side-by-side analysis of PEO providers, including how their insurance models stack up for companies at your headcount. Don’t auto-renew. Make an informed, confident decision.
Before you sign that PEO renewal, make sure you’re not leaving money on the table.
