TriNet review: the PEO that will not tell you the price

What you are actually buying from TriNet

A PEO is not an insurance company and not a broker. It becomes a co-employer of your staff for HR purposes, then buys workers' compensation, health coverage and payroll services at its own scale and resells them to you as a bundle. The U.S. Chamber of Commerce describes the arrangement plainly: the PEO becomes a co-employer and charges for the service.

That bundle is the product. You are not buying health insurance from TriNet. You are buying into TriNet's master health plan, alongside hundreds of other companies, administered on a fee that scales with your payroll. The health plan is real and often decent. The question is whether the wrapper is worth what it costs, and TriNet works hard to keep you from answering that question before you sign.

• Co-employment: TriNet shares employer responsibilities for your staff. Your employees keep working for you, but on paper there are two employers.
• Master plans: health coverage comes through TriNet's own arrangements, not a plan you select and own.
• Bundled payroll and HR: payroll processing, the HR portal, compliance support and benefits administration arrive together.
• Workers' compensation: usually part of the package, which is why leaving a PEO is messier than leaving a broker.

TriNet will not publish a price. That is the point.

I have read every TriNet marketing page I can find, twice. There is no pricing table. There is no per-employee-per-month figure. There is a page that explains what factors go into a quote: the number of employees, the states you operate in, the benefits you choose, your workers' compensation risk class. Then it asks you to talk to sales.

Compare that with the PEO market as a whole. The U.S. Chamber of Commerce puts PEO fees at 2% to 12% of monthly payroll, or roughly $50 to $250 per employee per month. That is a spread of six times, top to bottom. A fee that varies by 6x is not a price. It is a negotiation, and the party with the spreadsheet wins. TriNet has the spreadsheet.

Instead of prices, TriNet publishes outcomes. The company states that clients see an average of $234,000 in HR-related time savings over three years, a 66% return on their investment, and payback in under six months. Those numbers may well be true. They are also a sales argument, and an argument is not a bill.

Three things you stop owning

I am not against bundling in principle. Small teams genuinely benefit from someone else handling payroll filings and COBRA notices. But a TriNet contract takes three forms of control away from you, and founders usually discover this in year two, not month one.

• Plan design. You choose from TriNet's menu, not from the whole market. If your engineers want a specific network, or your team has a specialist in another city, the answer is whatever TriNet offers that year.
• The carrier relationship. The group policy is TriNet's, not yours. You cannot call the carrier and change a contribution level, and you cannot shop a renewal without TriNet's help.
• Your own employer identity. Your payroll tax registrations sit inside the arrangement. Leaving means registering as an employer again in every state where you have staff.

None of this is dishonest. It is simply the trade. The problem is that TriNet sells the bundle on HR convenience and lets you assume the insurance is handled just as well as it would be if you ran it yourself. It usually is not. It is handled the way a large administrator handles a thousand other companies at once.

The renewal is where the relationship changes

Year one is friendly. Year two arrives as a renewal letter with a percentage on it and very little detail about what moved. This is the standard PEO experience, and there is a reason for it: once your payroll tax registrations, workers' compensation and health plan all sit inside one vendor, switching costs real work. Your negotiating position weakens every month you stay.

Ask a TriNet client what their health plan costs separately from the service fee and you will usually get a pause. It is one number. A single invoice looks tidy and hides the fact that you cannot tell whether the health coverage went up 4% or the administration fee went up 15%.

What leaving TriNet costs you

Leaving a PEO is the part of the brochure that does not exist. It takes a written notice period, usually 30 to 90 days, timed to the end of your plan year or a 30-day window. Your health plan must be replaced without a gap, or your employees lose coverage and everyone with a claim in progress has a problem. Your tax registrations have to be reactivated in every state.

1. Read the notice clause now, not later Find the exact window in your TriNet agreement. It is usually tied to your renewal date, and missing it by a week can cost you a year.
2. Get a real group quote first You need a plan with a start date before you tell TriNet anything. Ask for a full rate table on your actual census, not a range.
3. Check workers' compensation If TriNet carries your workers' compensation, confirm your new policy is bound before the PEO end date. A lapse here is expensive.
4. Re-register as an employer Confirm new unemployment and withholding accounts in each state before the first payroll outside the PEO.

What to ask on a TriNet call

A PEO demo is a well-rehearsed hour about service. These questions turn it into a pricing conversation, which is the one you actually need.

• Give me the service fee as dollars per employee per month, not a percentage, and show the payroll figure it is applied to.
• What is the health plan's total cost on its own, separate from the service fee, for my census at my current contribution level?
• What did you charge an equivalent client at renewal last year, in percent?
• Which carrier and network would my team actually be on, and can I see the rate table?
• What is the notice period, and what date does it attach to?
• If we hire in a new state, what changes and what does it cost?
• When we leave, what happens to our claims history, our tax IDs and any prepaid balance?

Who TriNet fits, and who should walk away

I will give TriNet its due. If you are 20 people with staff in six states, no HR function, and a founder who would rather do anything than read a state unemployment notice, a PEO genuinely removes work from your week. The bundle is not a trick. It is an expensive convenience for people who need the convenience.

If you are in the middle band and the only thing keeping you at TriNet is fear of the exit, that is worth naming. The exit is one open-enrollment cycle of work, once. The fee is every month, forever.

How I would compare TriNet with a real quote

Do not compare marketing. Compare one number: total annual cost of health coverage plus administration, for the same census and the same contribution level. Ask TriNet for it in writing, split into insurance and service fee. Then ask anyone else for the same thing.

The average employer plan cost KFF reported for 2025 was $9,325 for single coverage and $26,993 for family coverage, and that is before any PEO fee. If the all-in figure you are quoted lands more than 10% to 20% above comparable fully insured coverage, the bundle is costing you money you could be putting into the plan itself.
