PEO Services: 7 Providers Compared for Small Business

Almost every guide to PEO services is written by a company that sells one. Keep that in mind, because the most useful thing a comparison can tell you as a small business owner is not which PEO is best, but whether you need a PEO at all. For a large share of small businesses, the honest answer is no, and no vendor-authored page will say so.

This page does two things. It compares the leading professional employer organizations on cost, pricing model, and fit, the way the ranking guides do. And it lays out a neutral framework for deciding between a PEO, HR software, and an employer of record based on your size and your actual problem, so you can tell whether a PEO is the right tool before you talk to a sales team.

What a PEO service actually is

A professional employer organization is a company you partner with to outsource the administrative burden of employing people. Through a legal arrangement called co-employment, the PEO becomes the employer of record for tax, benefits, and insurance purposes, while your business stays the worksite employer that directs the actual work. Your employees remain your employees in every way that matters day to day.

The reason small businesses use PEOs is benefits. Because a PEO pools the employees of hundreds or thousands of client companies, it can offer health insurance, retirement plans, and other benefits priced like those of a large corporation. That means a small team partnering with a PEO can offer the kind of health plan it could never negotiate on its own. Alongside that, the PEO handles payroll, tax filing, workers' compensation, and compliance guidance.

How co-employment works

Co-employment splits employer responsibilities between your business and the PEO. It is the mechanism that makes everything else possible, and it is the part most business owners find confusing.

The PEO takes on the obligations that come with being the employer of record: withholding and remitting payroll taxes under its own identification number, administering benefits, and carrying workers' compensation. You retain everything to do with running your business: who to hire, who to let go, what people work on, and how they are managed.

This is not staffing, leasing, or outsourcing your workforce. Your employees do not become the PEO's employees in any practical sense, and you do not lose control of your team. The arrangement exists so the PEO can legally pool your staff into its benefits and insurance programs and take the compliance-heavy administration off your desk.

Workers' compensation through a PEO

PEO workers' comp normally means your employees are covered under a master policy carried by the PEO rather than a policy in your own name. The premium is billed with each payroll run instead of through a deposit and an annual audit, and the PEO's risk team handles claims and return-to-work for injured employees.

For a small employer, that is often the most valuable part of the arrangement after benefits. There is no large deposit up front and no year-end audit bill to absorb. A business with a hazardous class code (the job classification that sets its rate) or a rough loss history can also get covered inside the master program rather than the state assigned risk plan. That plan is the coverage of last resort for employers that insurers will not take on voluntarily.

The rules are set at state level and they are not uniform. Virginia allows a PEO covering its co-employees to secure that insurance in the voluntary market under a master workers' compensation policy in the PEO's name, according to the Virginia Workers' Compensation Commission.

Texas takes a different route. Either the client or the PEO may offer the coverage, and the Texas Department of Licensing and Regulation requires the professional employer services agreement to state which party maintains it. Read your own agreement rather than assuming the PEO carries the policy everywhere you operate.

Ask two questions before you sign. First, what happens to your claims history when the relationship ends, and can you document it for a new carrier? A clean record you cannot evidence is worth little at renewal. Second, is the comp rate you are quoted fixed, or does it move with the master program's results?

What PEO services cost

PEO pricing comes in two shapes, and the difference matters for a growing team. A flat per-employee-per-month fee charges a set amount for each employee, which makes budgeting predictable and does not rise when you give raises. A percentage-of-payroll model charges a share of wages, which means every raise, bonus, and commission increases your PEO bill.

ADP's guide to PEO costs, updated July 2026, gives the range for each shape: about $40 to $160 per employee per month as a flat fee, or 2 to 12 percent of total payroll as a percentage. Treat that as one provider's view of the market rather than a price list, and ask every shortlisted PEO for its own figure.

The administrative fee is only part of the picture. It pays for the PEO's service and access to its benefits pool, but the actual benefits premiums, payroll taxes, and workers' compensation are passed through on top. When comparing providers, the number that matters is total cost of employment, because a provider with a higher admin fee but a stronger benefits pool can work out cheaper overall. Most PEOs quote only after a sales conversation, which makes the few that publish rates easier to evaluate.

7 PEO providers compared

The table below covers the leading PEO providers for US small and mid-sized businesses, with each one's published administrative fee, where it has one, and the pricing model it uses. Only Justworks and Deel publish PEO rates; the rest quote their PEO after a sales conversation, so the table marks their fees as not published rather than guessing.

Justworks is the most transparent provider in the market, one of the very few PEOs that publishes per-employee rates, with no implementation fee and no base fee on either PEO plan.

Justworks PEO Basic covers multi-state payroll, tax filing, compliance tools, access to workers' compensation, 401(k), and 24/7 support, while PEO Plus adds health insurance administration, health savings and flexible spending accounts (HSA and FSA), and mental health and fertility benefits. That mix suits startups and small teams that value predictable pricing over deep customization.

TriNet organizes its offering around industry verticals such as technology, financial services, life sciences, and consulting, tailoring benefits and compliance to the needs of each. That vertical focus is the main reason to choose it: a business in one of its target industries gets benefits and risk management shaped for that sector rather than a generic package.

TriNet serves teams from small businesses into the mid-market and is listed on the New York Stock Exchange, which lends stability. Pricing is quote-only, and TriNet says it charges a flat fee per employee per month, never a percentage of payroll.

ADP bills TotalSource as the nation's largest IRS-certified and ESAC-accredited PEO, backed by the scale, benefits buying power, and benchmarking data of a payroll business that, by ADP's own count, pays 1 in 6 US workers. That scale is its strength: deep benefits options, extensive compliance infrastructure, a dedicated HR business partner for every client, and a large integration marketplace behind the service.

TotalSource suits growing small and mid-size companies that want an established provider they will not outgrow. Pricing is quoted rather than listed, and ADP says it depends on workforce size, injury risk, and multi-state complexity.

Insperity is built around a high-touch service model, with HR and client service staff in most of its sales markets and face-to-face HR support delivered locally. Its annual report describes a core offering for small and medium-sized businesses and a separate middle-market service for companies of roughly 150 to 5,000 worksite employees, covering benefits, workers' compensation, risk management, and training.

Insperity quotes every client individually. Its pricing page says an HR360 fee combines direct costs, such as payroll taxes, workers' compensation, and benefits, with an HR service charge set as a fixed dollar amount per employee that does not rise when you give raises. For a business that values a hands-on, consultative relationship and can absorb the cost, the service depth is the draw.

Paychex PEO builds on the company's long history in payroll. Its HR PEO package runs on the same Paychex Flex platform as its payroll packages and sits beside HR Pro, a non-PEO service that provides a dedicated HR professional without co-employment. It offers all-in-one HR technology, payroll, benefits, and compliance, and every package is priced by quote. For a micro or small business that already uses Paychex for payroll, moving to its PEO is a low-friction step that consolidates the relationship into one vendor.

Rippling offers its PEO as a layer on top of its unified HR, payroll, and IT platform, aimed at tech-forward teams that want deep automation. Its standout feature is flexibility: Rippling says it is the only provider that lets you move off its PEO without replacing the underlying system, which removes the usual pain of leaving a PEO once you outgrow it.

The Rippling PEO itself is quote-only and sits on top of the core Rippling Platform, which every customer buys. Note that Rippling does not appear on the IRS list of certified PEOs, which is worth weighing against the certified providers on this list.

Deel is global-first, best known as an employer of record for international hiring, and it offers a US PEO across all 50 states. Its pricing page lists PEO Starter at $110 per employee per month, without PEO-sponsored health benefits, and PEO Pro at $120, while its US PEO page gives a starting price of $125. Its natural buyer is a company that already uses Deel to hire and pay people abroad and wants to consolidate its US employees onto the same platform. For a purely domestic small business with no international footprint, a dedicated US PEO is usually the more focused choice, but for a distributed team the single-platform consolidation is the appeal.

CPEO and ESAC status are federal and industry credentials, but they are not the only register worth checking. Most states also license or register PEOs separately, usually through the department of insurance or the labor agency, and commonly require a surety bond so there is something behind your payroll taxes if the provider fails.

The requirements and the regulator vary by state: a PEO operating in North Carolina, for example, must hold a Department of Insurance license backed by a $100,000 surety bond, letter of credit, or cash deposit, while other states set different bond amounts or run a lighter registration regime. Ask any shortlisted provider which states it is licensed in, and confirm it with that state's regulator rather than the provider's own website.

Certification also changes who owes the tax. The IRS generally treats a certified PEO as solely liable for federal employment taxes on the wages it pays your worksite employees. It files under its own identification number and reports each customer's share on a Schedule R, the allocation schedule attached to its return. That statutory protection does not extend to an uncertified provider, which is why the accreditation question is worth asking early.

What people mean by PEO software

Every PEO ships a client platform, and what gets called PEO software is usually one of the providers above rather than a separate category of product. What differs between them is how much of a system you actually get: a full HR record with self-service and reporting, or a payroll and benefits portal with a thin HR layer bolted on.

Test it during the sales process rather than after. Ask to see how a manager adds a hire, where documents live, what an employee sees when they log in, and what reporting you can pull without calling support. A platform you cannot operate day to day costs you the administrative time you bought the service to save.

When a PEO makes sense

A PEO makes sense when your business fits a specific profile, and when it does, signing up can be one of the most valuable decisions a small business makes. NAPEO, the industry association, reports that businesses using a PEO grow twice as fast, have 12 percent lower employee turnover, and are 50 percent less likely to go out of business than comparable companies that do not.

The clearest case is a small or mid-size company with no internal HR team, where benefits access and compliance offloading are pressing problems. If you are competing for talent and cannot offer a competitive health plan, or if payroll tax and compliance obligations across multiple states are consuming time you do not have, a PEO solves exactly that. The co-employment model turns a problem that would otherwise require hiring HR staff into a per-employee fee.

Remote and multi-state teams

A remote PEO is not a different product. It is the same co-employment arrangement applied to the part that hurts most for a distributed team: registering and filing in every state where somebody works, and offering a health plan with a usable network in all of them.

Keep two cautions in mind. Ask which states a provider is licensed or registered in before assuming national coverage, and ask how the health plan performs where your people actually live rather than where you are. A large national pool with thin local networks is a common disappointment.

International PEO is a marketing label rather than a separate legal arrangement. What is sold under that name is an employer of record, which becomes the full legal employer abroad so you can hire where you have no entity. It is contracted and priced differently from a domestic PEO, so treat it as a separate decision.

When you do not need a PEO

You usually do not need a PEO in three situations: your team is still small, your main need is HR administration rather than benefits, or you already have HR capacity in-house. A large share of small businesses that consider a PEO would be better served by something simpler and cheaper, and most PEO guides leave that out because the companies writing them sell PEOs.

If your team is still small, the per-employee fees rarely justify themselves unless benefits access is your single biggest problem. If your main need is organizing HR, running onboarding, storing documents, and giving employees self-service rather than getting group benefits, that is a job for HR software, not a co-employment relationship. And if you already have internal HR capacity, paying a PEO per employee often costs more than keeping HR in-house and equipping it with the right tools.

The decision comes down to your actual problem. A PEO solves benefits access and compliance offloading. If that is not what you need, a per-employee PEO fee is an expensive way to get HR administration you could handle with software at a fraction of the cost.

PEOs for very small teams and single employees

Providers do take small clients. Published minimums in this market start at around two to five people (Justworks counts an unpaid owner as one of its two), and several providers do not publish a minimum at all, so a two-person company can be placed. Whether it should be is a different question.

At one or two employees, the per-employee fee buys administration you can do yourself in an hour a month, and a solo owner with no W-2 staff has nobody to co-employ in the first place. If the goal is health coverage for one or two people, a marketplace plan or a small-group plan through a broker is normally cheaper.

Before you choose: PEO vs HR software

Many businesses shopping for a PEO are really trying to solve an HR administration problem, not a benefits problem, and for that, HR software is the simpler and less expensive answer. If the section above made you suspect you might not need a PEO, understand that alternative clearly before you commit to a co-employment relationship.

FirstHR is an HR software platform, not a PEO. It does not co-employ your staff, run payroll, or provide a benefits pool, so if group health insurance and compliance offloading are your real needs, a PEO from the comparison above is the right direction. What FirstHR does instead is handle the HR administration many businesses mistakenly shop for a PEO to solve: onboarding with an AI wizard, e-signature for hiring documents, an employee database, document management, an org chart, and a self-service portal, at a flat $98 to $198 per month that does not rise with headcount.

A common and cost-effective setup for a small team is HR software for administration paired with a standalone benefits broker for insurance, which together often cost far less than a per-employee PEO fee.

How to choose a PEO provider

Choosing a PEO provider comes down to five questions, asked in order. Settle whether you need a PEO at all before you compare accreditation, total cost, benefits fit, and contract terms, because the first answer decides whether the other four matter.

What a PEO transition involves

A PEO transition is an implementation project rather than a signup. Plan for several weeks between the signed agreement and the first payroll that actually runs on the provider's system, and expect the work to land on whoever owns payroll and benefits today.

You supply the raw material: employee records, year-to-date wage and tax figures, benefit elections and dependents, job classifications for workers' compensation, and any active leave or garnishment. Ask specifically how year-to-date wages carry across, because that answer decides whether wage bases (the annual wage caps for taxes such as Social Security) restart partway through the year.

Timing is worth choosing deliberately. A January start lines up with the tax year and with most plan years, which avoids the problems a mid-year move creates for deductibles already met and for employees midway through an enrollment cycle.

Leaving is the mirror image and gets far less attention during the sales process. Payroll, benefits, and coverage all sit in the PEO's name, so an exit means new plans, a new carrier, a new payroll system, and employee data exported into it. Ask up front what notice is required, what you can export, and in what format.

Frequently Asked Questions

What is a PEO service?

A PEO, or professional employer organization, is a company that becomes the co-employer of your staff and takes on the administrative side of employing them: payroll, tax filings, benefits, workers' compensation, and compliance. You keep running the business and managing your team. The main draw is benefits: because the PEO pools many client companies, a small business gets large-group benefits pricing it could not get alone. You pay an administrative fee, usually per employee per month or as a percentage of payroll.

What are PEO services and how do they work?

PEO services cover the administrative side of employing people: payroll, tax filing, benefits, workers' compensation, and compliance. They work through co-employment, where the PEO becomes the employer of record for tax and insurance purposes while you remain the worksite employer directing the work. Your employees stay yours; the PEO takes over the back-office obligations and provides its benefits pool.

How much do PEO services cost?

Pricing follows one of two models. ADP's guide to PEO costs puts a flat fee at about $40 to $160 per employee each month and a percentage fee at 2 to 12 percent of total payroll, with benefits and taxes billed on top. Justworks publishes $79 and $124 per employee for its two PEO plans, and Deel lists $110 and $120 PEO plans on its pricing page and $125 on its US PEO page. Most providers quote after a sales conversation. Compare total cost of employment, not the admin fee alone.

What is co-employment?

Co-employment is the legal arrangement behind a PEO. Your business and the PEO share employer responsibilities: the PEO becomes the employer of record for payroll taxes, benefits, and workers' compensation, while you keep hiring and firing decisions and day-to-day management. It is not staffing or leasing, and your employees do not become the PEO's workforce.

Do I need a PEO for a small business?

Not always. A PEO makes the most sense for a small or mid-size company with no internal HR that wants group benefits and compliance help. For a smaller team, or if your main need is HR administration rather than benefits, HR software is usually a better fit at a fraction of the cost. The test is whether affordable group benefits and compliance offloading are your real problem.

What is the difference between a PEO and HR software?

A PEO is a co-employment service where people handle your payroll, benefits, and compliance and you gain access to a benefits pool, for a per-employee fee. HR software like FirstHR is a tool you run yourself to manage records, onboarding, documents, and self-service, at a lower and more predictable cost. Many businesses that think they need a PEO actually need HR software plus a standalone benefits broker.

What is the difference between a PEO and an EOR?

A PEO co-employs workers you have hired in a country where you have a legal entity. An employer of record, or EOR, becomes the full legal employer on your behalf so you can hire in countries where you have no entity. A PEO is for domestic co-employment; an EOR is for international hiring. If your question is about employing someone abroad, you need an EOR.

How do I choose a PEO provider?

Confirm the provider is IRS-certified and ESAC-accredited, then compare on pricing transparency, benefits pool quality, service model, and industry fit. Ask for the total cost of employment at your actual size, not just the admin fee, and check for implementation fees and contracts. Decide whether you need a PEO at all before shortlisting, since the wrong tier or model can cost more than it saves.
