How we make this list: we compare pricing pages, product documentation and public user reviews. Ratings come from G2, Capterra or Trustpilot, with the date we checked them.
Key takeaways
- Only Justworks and Deel publish PEO prices among major providers; everyone else builds a quote from your employee census.
- IRS Certified PEO status matters: Justworks, TriNet, ADP TotalSource, Insperity, Paychex and Sequoia One hold it, while Rippling and Deel do not.
- Minimums vary widely, from 2 employees at Justworks to 10 or more at Insperity, so size alone can rule providers in or out.
- Compare total per-employee cost, benefits quality, setup fees and exit terms, not just the headline rate, and collect at least three quotes.

The best peo companies
Starting price$79 per employee per month
Free planNo
Justworks is the only major PEO publishing flat per-employee pricing on its website, with Basic at $79 and Plus at $124 per employee per month and no base fee, which lets a small team budget without a sales call. It holds IRS Certified PEO status, serves teams from just 2 W-2 employees, and covers the standard PEO bundle: payroll processing, payroll tax administration, year-end tax reporting, benefits plans and compliance help.
The limits are depth and terms. Benefits quality trails the largest PEOs, industry specialization is thinner than TriNet's vertical pods, and no contract term is published, so exit mechanics need confirming with support before signing. For seed-stage teams of 2 to 25 people who want transparent pricing and simple setup, Justworks is the clearest starting point in the market.
What we like- Published pricing at $79 Basic and $124 Plus per employee per month
- IRS Certified PEO
- Minimum of just 2 W-2 employees
Watch out for- No published contract term
- Benefits depth trails larger PEOs
- Less industry specialization than TriNet

TriNet is the best choice for industry-specific HR support, especially in technology, life sciences and financial services, where its vertical pods understand the hiring, benefits and compliance patterns of each sector. It holds IRS Certified PEO status through a subsidiary, serves companies from 5 to 500 employees, and offers partner programs for VC-backed firms. For a funded tech company, that specialization is a genuine advantage over generalist PEOs.
The downsides are price opacity and contract terms. Pricing is by quote only, the annual contract auto-renews with usually 30 days notice, and public reviews cite fees for small items and slow support escalation. Collect a detailed quote, confirm every fee in writing, and diary the renewal notice date before signing. For industry depth at scale, TriNet remains a top pick despite those cautions.
What we like- Deepest vertical specialization in tech, life sciences and financial services
- IRS Certified PEO through a subsidiary
- Partner offers for VC-backed firms
Watch out for- Pricing by quote only
- Annual contract that auto-renews with usually 30 days notice
- Complaints about fees and support responsiveness
#3ADP TotalSource
Best for: Large-company benefits at scale4.3/5 on

Free planNo
ADP TotalSource is the largest PEO in the US by worksite employees, and its scale buys benefit quality: Fortune 500-grade plans that small firms could not negotiate alone, plus a deep compliance bench for multi-state payroll tax work. It holds IRS Certified PEO status, serves companies from 50 to 500 employees with a sweet spot around 75 to 200, and suits startups expecting to scale large without switching providers.
The fit starts high: teams under 50 employees will find better pricing and attention elsewhere, and pricing is by quote only, based on headcount, risk and location. The large-vendor feel can also frustrate small teams used to named contacts. For a 50-plus employee company that wants large-company benefits and a provider that scales, ADP TotalSource is the best overall PEO for mid-size firms.
What we like- Largest US PEO by worksite employees
- Fortune 500-quality benefit plans
- IRS Certified PEO
- Deep compliance bench
Watch out for- Pricing by quote only
- Best fit starts around 50 employees
- Large-vendor feel for small teams
#4Insperity
Best for: High-touch HR service4.3/5 on

Insperity is the white-glove PEO: a dedicated HR business partner backed by roughly 90 regional offices with named service teams, rather than a call-center queue. It holds IRS Certified PEO status, targets companies from 10 to 5,000 employees with a sweet spot around 50 to 200, and prices as a percentage of payroll rather than a flat per-employee fee. For founders who want a named partner for tricky HR questions, that model is the appeal.
Pricing is by quote only and usually fixed for one year with 30 days written notice for changes, so budgeting needs a full quote, and the premium service comes at a premium cost. Small teams under 10 employees should look at Justworks or Paychex instead. For companies that want high-touch HR service and a partner who knows their business, Insperity is the strongest pick.
What we like- Dedicated HR business partner
- Roughly 90 regional offices with named service teams
- IRS Certified PEO
- Percentage-of-payroll pricing
Watch out for- Pricing by quote only, usually fixed for one year
- Targets 10 to 5,000 employees
- Premium feel at a premium cost

Rippling PEO suits tech-first teams that want HR, payroll, IT and device provisioning in one native system, with no third-party bolt-ons. The standout feature is exit flexibility: a team can switch the PEO off and stay on Rippling's HR platform, which removes the usual fear of being locked into a PEO forever. Pricing is a flat per-employee rate, quoted per team, with a sweet spot around 25 to 300 employees.
The gaps are certification and support depth. Rippling is not an IRS Certified PEO, which matters for tax liability protection, and support trails high-touch rivals like Insperity. Pricing is by quote only. For a tech team planning to leave the PEO later, or one that values unified HR and IT above certification, Rippling is the smartest choice.
What we like- HR, payroll, IT and device provisioning in one system
- Can switch the PEO off and stay on the HR platform
- Flat per-employee rate
Watch out for- Not an IRS Certified PEO
- Pricing by quote only
- Support depth trails high-touch rivals

Paychex PEO is the small business pick for payroll depth. It holds IRS Certified PEO status, its band starts at 5 employees with a range up to 500, and it brings one of the deepest multi-state tax compliance benches in the industry, which matters for teams hiring across states. Phone support runs 24/7, a genuine edge over rivals with business-hours-only help.
Pricing is by quote only, and the interface feels traditional next to Rippling's modern platform, since PEO is one of many Paychex services rather than the whole product. For a small business that wants certified PEO coverage, payroll depth and round-the-clock phone support, Paychex PEO is a reliable and often overlooked choice.
What we like- IRS Certified PEO
- Band starts at 5 employees
- Deep multi-state tax compliance bench
- 24/7 phone support
Watch out for- Pricing by quote only
- Interface feels traditional next to Rippling
- PEO is one of many Paychex services

Deel PEO is the pick for teams that mix US employees with international hires. It publishes a US PEO price of $125 per employee per month, one of only two major PEOs with a public price, and it pairs US PEO coverage with international hiring, payroll and contractor management in many countries. The list price is month-to-month, which suits teams that want flexibility.
The cautions are certification and promo terms. Deel is not an IRS Certified PEO, a US entity is required for the PEO, and the current promotion requires a 2-year term, which undercuts the month-to-month headline. For a US team plus international hires under one vendor, Deel is still the most convenient option, but confirm the promo terms before signing.
What we like- Published US PEO price of $125 per employee per month
- Pairs with international hiring in many countries
- Month-to-month list price
Watch out for- Not an IRS Certified PEO
- US entity required
- Current promo requires a 2-year term

Sequoia One is a PEO built for VC-backed tech startups, pairing PEO coverage with compensation and benefits strategy that fits how startups hire and retain. It holds IRS Certified PEO status, which gives tax liability protection that non-certified rivals lack, and its team understands equity, benchmarking and benefits design for venture-backed firms. For a startup planning rapid hiring, that strategic help matters as much as payroll processing.
Pricing is by quote only, and contract and exit terms are not published, so both need confirming before signing. Generalist appeal is narrower than ADP or Paychex, since the model is tuned to venture-backed tech. For a VC-backed startup that wants certified PEO coverage plus compensation strategy, Sequoia One is a strong specialist pick.
What we like- IRS Certified PEO
- Compensation and benefits strategy for startups
- Strong with VC-backed tech companies
Watch out for- Pricing by quote only
- Contract and exit terms not published
- Narrower generalist appeal than larger PEOs
How we chose
We compared PEOs on published pricing, IRS Certified PEO status from the IRS active list dated August 2026, stated minimums, contract and exit terms, and fit by company size, using October 2026 PEO comparisons that checked each vendor's own site. Only Justworks and Deel publish a PEO price, while TriNet, ADP, Insperity, Paychex, Rippling and Sequoia One require a census-based quote. Minimums range from 2 employees at Justworks to 10 or more at Insperity.
We also weighed certification heavily, since IRS Certified PEO status shifts certain federal employment tax liabilities to the PEO, which is a real legal protection, not a badge. No PEO here was used hands-on for this guide; the picks rest on published pricing, certification lists and documented terms, not on personal client experience.
What to check before you sign
Get at least three quotes, since benefits costs depend on your team's ages, locations and salaries, and no headline rate captures your real cost. Ask for total per-employee cost including benefits, setup fees, admin fees and any per-item charges, and confirm them in writing, since public reviews of some providers cite fees that were not disclosed upfront.
Check certification, minimums and exit terms in the same conversation. Confirm IRS Certified PEO status, confirm your headcount fits the provider's band, and diary renewal and notice dates, since TriNet auto-renews annually and Insperity pricing is usually fixed for one year. Finally, decide whether you need a PEO at all: hiring outside the US without an entity needs an employer of record, not a PEO, and a team planning to leave the PEO soon should favor Rippling's switch-off model.
Frequently asked questions
What is a PEO and how is it different from payroll software?
A PEO, or professional employer organization, co-employs your team: it handles payroll, payroll taxes, benefits, workers compensation and compliance under its own plans and tax IDs, while you keep day-to-day control. Payroll software only processes pay and filings, leaving benefits and compliance to you. PEOs suit firms that want large-company benefits and compliance help without an HR team.
How much does a PEO cost?
Only Justworks and Deel publish PEO prices: Justworks at $79 Basic and $124 Plus per employee per month, and Deel at $125 per employee per month. Other major PEOs quote per team, based on headcount, risk and location, with Insperity pricing as a percentage of payroll. Always compare total per-employee cost, not just the admin fee.
What does IRS Certified PEO status mean?
IRS certification means the PEO meets IRS requirements for financial responsibility, reporting and bonding, and it shifts certain federal employment tax liabilities to the PEO. Justworks, TriNet, ADP TotalSource, Insperity, Paychex and Sequoia One hold it; Rippling and Deel do not. Certification is a real legal protection worth weighing in your choice.
What is the minimum size for a PEO?
Justworks serves teams from 2 W-2 employees, Paychex PEO from 5, TriNet from 5 to 500, Insperity from 10, and ADP TotalSource from around 50. Smaller teams should start with Justworks or Paychex, while larger teams get better benefits depth from ADP or Insperity.
Can I leave a PEO easily?
It depends on the contract. Rippling lets you switch the PEO off and stay on its HR platform, TriNet auto-renews annually with usually 30 days notice, and Insperity pricing is usually fixed for one year. Confirm exit terms, notice periods and what happens to benefits coverage before signing any PEO contract.
Do I need a PEO or an employer of record?
Use a PEO for US employees when you have a US entity and want benefits and compliance help. Use an employer of record, or EOR, when hiring outside the US without a local entity, since a PEO cannot employ workers in a country where you have no entity. Deel offers both, which suits mixed US and international teams.
