Ares Benefit Group helps employers compare a professional employer organization arrangement with a group health plan the company sponsors itself. Ares is a benefits advisor, not a PEO. The general explainer of what PEO-arranged coverage is, including IRS certified PEO rules, is already on PEO health insurance. This page is the named-PEO companion: how Justworks, TriNet, Insperity, and ADP TotalSource describe their own PEO services, and how we set those models next to a carrier-issued group plan, a level-funded plan, or an ICHRA.
What a PEO is, in brief
The National Association of Professional Employer Organizations describes a PEO as providing human resource services to small and mid-size businesses, including paying wages and taxes under the PEO's EIN, workers' compensation and risk management, compliance help, and access to benefits such as health, dental, and life. The relationship is co-employment, set by a client service agreement. In NAPEO's description, the PEO typically remits wages and withholdings and issues the Form W-2 under the PEO's EIN, while the client company retains day-to-day operations, supervision, and business decisions. A longer, sourced version of those rules is on PEO health insurance.
The four PEOs employers ask us about
We do not rank these firms. Each description below uses that company's official wording.
Justworks. Justworks describes its PEO as an all-in-one payroll, HR, and benefits solution for U.S.-based employees, in a co-employment relationship. It publishes a PEO Basic plan and a PEO Plus plan. Plus includes medical, dental, and vision insurance; Basic includes access to health insurance reimbursements that Justworks calls CHOICE (formerly ICHRA) through an integrated partner, Thatch. Justworks also describes itself as IRS-certified and ESAC-accredited.
TriNet. TriNet describes its PEO as a complete HR solution for small and medium-size businesses, including payroll, access to benefits, compliance, workers' compensation, and an HR platform. Official FAQs state that TriNet gives small businesses access to comprehensive medical, dental, and vision plans, as well as a TriNet-sponsored 401(k). TriNet says it has maintained ESAC accreditation since 1995, and that a TriNet subsidiary holds IRS Certified PEO status. TriNet says business owners retain control over their workforce, company culture, and brand.
Insperity. Insperity's official FAQs describe a PEO as a full-service HR partner that assumes certain employer-related responsibilities through a co-employment relationship, while the client keeps control of daily business operations. Typical services listed there include payroll and HR administration, compliance guidance, access to PEO-sponsored benefit plans, HR technology, and support from an HR team. Insperity also describes common PEO pricing models (a percentage of gross payroll, or a flat charge per employee) without stating a rate, which matches how we will compare proposals: on the actual quotes, not on a generic fee.
ADP TotalSource. ADP describes TotalSource as an IRS-certified (CPEO) and ESAC-accredited PEO that supports businesses with 5 to 1,000+ employees across all 50 states. Official pages describe co-employment, with ADP taking on administrative HR work — payroll and employment-tax administration, employee benefits access and administration, HR compliance guidance, and workers' compensation — while the client stays in control of day-to-day operations and employee decisions.
Other PEOs exist, including firms such as Paychex that officially describe PEO services. If you already work with a different PEO, we can still compare that arrangement with a plan you would sponsor yourself.
How a PEO differs from a group plan you buy from a carrier
In a company-sponsored plan — a fully insured small-group policy, a SHOP policy, a level-funded plan, or a self-funded plan — the employer (or its stop-loss and administrative partners) is the plan sponsor, and Ares helps you compare carriers and put the chosen design in place, including Section 125 administration and voluntary benefits. In a PEO arrangement, the PEO typically sponsors or arranges the benefits under the co-employment structure, and payroll often runs under the PEO's EIN.
Both models can include medical, dental, vision, and life coverage. The deciding facts are usually who the plan sponsor is, what happens at renewal, what it takes to leave, and whether a carrier-issued plan, an ICHRA, or a QSEHRA is the cleaner fit for the census. ADP's official PEO FAQs note that when you leave a PEO, the business becomes responsible for setting up and administering its own benefits, and that the transition should be planned to avoid a coverage gap. That is a process point, not a reason to avoid PEOs; it is a reason to plan an exit or a broker change carefully.
How PEOs compare with an ICHRA
A PEO is a co-employment and HR-outsourcing model that can include group benefits. An ICHRA is a defined-contribution reimbursement arrangement the employer sponsors, often with an administrator such as Take Command, Thatch, or PeopleKeep. Justworks even describes an ICHRA-style reimbursement option (CHOICE) on its PEO Basic plan, through Thatch, which is a reminder that the two models can sit near each other rather than only as substitutes. We will recommend the design the rules and the census actually support.
Can we leave a PEO and move to a Florida Blue or UnitedHealthcare small-group plan?
In principle, a company can end a PEO relationship at renewal or at an agreed date in the client service agreement, and then look at a company-sponsored plan. For a Florida employer, the fully insured small-group starting points are Florida Blue, UnitedHealthcare, and AvMed. We would quote the group market and the census. We will not promise underwriting results or a gap-free date until the contracts are in hand.
What we need for a proposal
We need a census, the current PEO or plan (if any), the worksite states, the renewal or agreement end date, and whether you want to stay in a PEO, leave one, or compare both. Employee benefits consulting is available when the question is broader than a single product.

What is a PEO, in plain terms?
A professional employer organization co-employs your worksite staff under a client service agreement and typically handles payroll under its EIN, plus specified HR, tax, and benefits functions. NAPEO's official FAQs are the source for that description. The longer explainer is on PEO health insurance.
If we use a PEO, who is the employer on the W-2?
In NAPEO's description, the PEO issues the Form W-2 for compensation it pays under the PEO's EIN. The client company remains the day-to-day employer of the business.
How is a PEO different from a group plan we buy from a carrier?
A carrier-issued group plan is sponsored by your company. A PEO typically sponsors or arranges benefits inside a co-employment relationship, often alongside payroll and HR services.
Can we leave a PEO and buy a Florida Blue or UnitedHealthcare small-group plan?
It is possible in principle at a renewal or an agreed end date. We would quote the Florida group market and the census, not promise underwriting results. Plan the transition so coverage does not lapse.
How do PEOs compare with an ICHRA?
They are different models: co-employment and often PEO-sponsored group benefits, versus a defined-contribution reimbursement the employer sponsors. Justworks also describes an ICHRA-style option on one of its PEO plans. We will compare both when both fit.
Where do Justworks, TriNet, Insperity, and ADP TotalSource fit?
Each is a PEO, or offers PEO services, in its official materials, as summarized above. We do not rank them. See the individual pages for sourced detail.
