If you're comparing HR outsourcing and PEO providers that serve Pennsylvania, I'd put these on the shortlist. There isn't one objectively "best" provider—the right fit depends heavily on headcount, industry, benefits needs, and whether you want a true co-employment PEO or simply outsourced HR support.

Strong Pennsylvania options

• ADP TotalSource — A strong option for companies wanting a large, full-service PEO. It combines payroll, benefits, HR, compliance, workers' comp and dedicated HR support. ADP says TotalSource is IRS-certified and ESAC-accredited and serves businesses from roughly 5 to 1,000+ employees.
• Insperity — Particularly worth considering if you want substantial HR expertise alongside payroll, benefits, compliance and HR technology. Insperity has offices in Philadelphia, Pittsburgh and the Philadelphia suburbs.
• Paychex PEO — A particularly relevant choice for Pennsylvania small and midsize businesses because Paychex has a dedicated Pennsylvania operation and offers payroll, HR, benefits and compliance through its PEO.
• TriNet — Worth including if your industry has specialized HR/benefits requirements. Independent comparisons commonly include TriNet among the major PEO alternatives.
• Justworks — A simpler PEO-oriented option to investigate if you're a smaller company and prioritize straightforward technology and pricing. Current industry comparisons include it among the leading PEO platforms.

Pennsylvania-based providers

If you specifically want a local/regional provider rather than a national PEO, I'd also investigate:

• CLEAR Employer Services — Pennsylvania-based PEO/HR outsourcing provider offering payroll, benefits, workers' comp/risk management and HR administration.
• Kismet PEO — Sharon-based PEO focused on small and midsize employers, with payroll, benefits, HR administration, compliance and an integrated HR platform.
• XpanseHR — Radnor-based outsourced/fractional HR firm; more oriented toward hands-on HR consulting and outsourced HR than a traditional national PEO.
• Payroll Service Solutions — Southampton-based payroll and HR outsourcing provider serving small and midsize businesses.
• Simplifi Payroll and HR — Bensalem-based provider focused on payroll and outsourced HR for small/midsize companies.
• Group Management Services — National PEO with a Cranberry Township/Pittsburgh-area office and a focus on small and midsize businesses.

How I'd structure the comparison

If your priority is…	Providers to investigate
Full-service national PEO	ADP TotalSource, Insperity, Paychex
Small-business PEO	Justworks, Paychex, ADP
High-touch HR expertise	Insperity, ADP, XpanseHR
Pennsylvania-based/local relationship	CLEAR, Kismet, XpanseHR, PSS
Payroll + HR without necessarily going full PEO	Paychex, ADP HRO, PSS, Simplifi
Specialized/industry-oriented HR	TriNet, Insperity

One important distinction: PEO and HR outsourcing aren't exactly the same thing. With a PEO, you're generally entering a co-employment arrangement in which the provider takes on specified employer responsibilities; an HRO/ASO arrangement can let you outsource HR/payroll functions without the same co-employment structure. ADP, for example, explicitly offers both models.

If you tell me (1) number of employees, (2) industry, (3) Pennsylvania city, (4) approximate annual payroll, and (5) whether you need health insurance/401(k)/workers' comp, I can narrow this to a 3–5 provider shortlist and compare likely pricing, benefits, service model, and Pennsylvania-specific considerations.

For a 10–200 employee company in Pennsylvania, I’d build a shortlist around a mix of national PEOs and Pennsylvania-based providers. The right choice depends heavily on whether you want a true PEO/co-employment model or simply outsourced HR/payroll (ASO/HRO).

Shortlist

Provider	Best fit to investigate	Why it stands out
CLEAR Employer Services	PA-focused SMBs, especially Eastern PA	Pennsylvania-based PEO with payroll, HR administration, benefits, workers' comp/risk management and compliance support. Its local presence and Pennsylvania benefits relationships can be particularly relevant.
Insperity	20–200 employees wanting high-touch HR	Full-service PEO/HR outsourcing with HR specialists, payroll, benefits, compliance and risk support. It has Pennsylvania offices in Philadelphia, Pittsburgh and the surrounding area.
Group Management Services	SMBs wanting a regional PEO	PEO with a Pennsylvania presence and an emphasis on outsourced HR administration, payroll, benefits and HR technology.
Kismet PEO	Smaller/midsize PA employers wanting a more local provider	Pennsylvania-headquartered PEO offering payroll, benefits, compliance, onboarding, time/attendance and other HR functions through an integrated platform.
TriNet	10–200 employees, particularly professional/regulated industries	Strong industry-specific HR and benefits orientation; commonly positioned for companies in this size range.
ADP TotalSource	Companies expecting growth or operating across multiple states	Large-scale payroll/HR infrastructure, broad compliance capabilities and a full PEO offering. ADP says TotalSource is IRS-certified and ESAC-accredited.
Paychex PEO	Payroll-centric SMBs	Established PEO with a strong payroll/HR platform and suitability for roughly 10–300 employee organizations.
Justworks	Smaller companies, especially ~10–75 employees	Particularly attractive if transparent pricing and a simpler technology experience matter. It publishes PEO pricing rather than requiring every prospect to request a quote.
XpanseHR	Companies that want outsourced HR without necessarily entering a PEO	Radnor-based outsourced/fractional HR and advisory firm; worth considering if you primarily need HR expertise rather than PEO co-employment.

How I'd segment the market

10–30 employees: Look closely at Justworks, CLEAR, Kismet and GMS. At this size, simplicity, minimums, benefits access and the amount of actual HR support you receive can matter more than having a massive enterprise platform.

30–100 employees: I'd put CLEAR, Insperity, TriNet, Paychex and ADP TotalSource on the initial quote list, with Justworks as a useful pricing/technology benchmark.

100–200 employees: I'd make Insperity, TriNet, ADP TotalSource, Paychex and a strong Pennsylvania/regional PEO such as CLEAR or GMS the core comparison. At this size, benefits economics, workers' comp, multi-state compliance and service-team structure become increasingly important.

There isn't a universally "best" provider: current comparisons show substantial differences in pricing models and service approaches, and most large PEOs don't publish their actual PEO price.

One important Pennsylvania-specific consideration

If your employees are primarily in Pennsylvania, don't automatically assume a national PEO will be cheaper or better simply because it has greater scale. A PA-focused provider may have particularly relevant knowledge of local payroll, workers' compensation and benefits considerations. Conversely, if you're hiring across several states, the national providers' infrastructure may become more important.

Also distinguish PEO vs. HR outsourcing/ASO:

• PEO: co-employment arrangement; provider typically handles payroll, benefits administration, workers' comp and substantial HR/compliance functions.
• ASO/HRO: you remain the sole employer while outsourcing selected HR/payroll functions.
• If you already have a competent payroll system and benefits broker, an ASO can sometimes be a better structural fit than paying for a full PEO.

What I'd ask each provider to quote

Don't compare just the advertised PEPM fee. Ask every finalist for the same 12-month total-cost model, including:

• PEO/admin fees
• Medical, dental and vision premiums
• Employer benefits contribution
• Workers' compensation
• Payroll taxes/SUTA
• 401(k) fees
• EPLI and other insurance
• Implementation/setup fees
• Renewal increases or rate caps
• Termination fees and notice period
• Multi-state employee fees, if applicable

This matters because the PEO's administrative fee is only part of the economics; benefits, workers' comp and payroll taxes can materially change the final cost.

If you tell me your approximate headcount (e.g. 25, 75, or 150), industry, whether everyone is in PA or you have multiple states, and whether you want a PEO vs. just outsourced HR/payroll, I can narrow this to a 3–5 provider comparison with current pricing/fee structures and Pennsylvania-specific considerations.

• Insperity · Payroll Services
• CLEAR Employer Services · 4.7★ · Human resource consulting

If by “best employee benefits” you mean health insurance breadth, dental/vision, retirement, ancillary benefits, and the ability to offer competitive plans to Pennsylvania employees, I’d put these providers on the shortlist:

PEO	Benefits strengths	Particularly worth considering if…
ADP TotalSource	Broad health, dental, vision, 401(k), mental-health and other benefits; customizable plan design; multiple major carriers	You have a growing or multi-state workforce and want substantial benefits flexibility
Insperity	Strong bundled benefits, HR support, retirement and risk-management services	You want a high-touch HR/benefits relationship
TriNet	Broad benefits portfolio and industry-oriented plan options	Your workforce has specialized needs or you want industry-specific benefits support
Justworks	Health, dental, vision, 401(k), life/disability and other benefits with relatively transparent pricing	You're a smaller Pennsylvania employer and want a simpler PEO
CLEAR Employer Services	Pennsylvania-focused PEO with employee benefits and a relationship with Independence Blue Cross	You want a regional provider with Pennsylvania-specific benefits expertise

My practical shortlist

ADP TotalSource is particularly notable for benefits flexibility. ADP says its PEO can provide health, dental, vision, 401(k), mental-health and pet-wellness benefits, with plan designs through leading carriers and benefits administration handled by ADP. It also offers a 401(k) multiple-employer plan.

Insperity is another significant option in Pennsylvania, with a Philadelphia presence. Its model emphasizes bundled benefits alongside HR, compliance, workers' compensation and employee-relations support.

TriNet is worth getting a quote from if benefits customization by industry is important. Current comparisons identify it as particularly oriented toward industry-specific HR and benefits needs.

Justworks is more attractive for smaller teams that prioritize simplicity and published pricing. Its PEO Plus offering includes health-insurance administration, while the broader PEO offering includes payroll, workers' comp, 401(k) administration and other HR services.

For a Pennsylvania-specific alternative, CLEAR Employer Services is headquartered in the state and offers PEO services including employee benefits. Its Pennsylvania positioning includes a relationship with Independence Blue Cross, which could be particularly relevant if your employees are concentrated in southeastern Pennsylvania.

The important catch

The provider with the “best” benefits on paper isn't necessarily the one that will produce the best actual benefits package for your employees. PEO health-plan availability and pricing can vary based on:

• Number of employees and dependents
• Employee locations within Pennsylvania
• Employee demographics
• Industry/workers' comp risk
• Desired employer contribution
• Preferred medical networks and carriers
• Whether you need HSA/FSA, fertility, mental-health, or specialty benefits
• 401(k) contribution/match requirements

So I'd ask each PEO for an actual Pennsylvania benefits quote, rather than comparing the marketing descriptions.

If you tell me your employee count (e.g. 10, 25, 50, 100), where in PA your employees are located, and whether you care most about low premiums, rich coverage, or recruiting-quality benefits, I can narrow this to the most relevant 3–4 providers and compare their benefits side-by-side.

• CTR Payroll & HR · 4.8★ · Business to business service
• Kismet PEO · 5.0★ · Human resource consulting

If your priorities are payroll accuracy + Pennsylvania/federal compliance + outsourced HR support, I’d put these providers on a practical shortlist:

• CLEAR Employer Services — PA-based PEO option. Offers payroll/tax administration, HR outsourcing, benefits, workers’ comp, and compliance support. Its PEO model is particularly relevant if you want to transfer some employer-administration responsibilities rather than simply buy payroll software.
• Insperity — Full-service HR/PEO. Strong fit when compliance and ongoing HR guidance matter as much as payroll. Its services include payroll, HR compliance/risk support, workers’ comp, and assistance with wage claims and audits.
• Simplifi Payroll and HR — Local, hands-on alternative. Based in Bensalem and focused on small/midsize businesses, with payroll processing/tax filing and an outsourced HR/compliance component.
• Payroll Service Solutions — Philadelphia-region payroll + HR. Provides payroll, tax compliance, HR outsourcing, and employer support for state/local/federal requirements.
• CTR Payroll & HR — Western PA option. Combines payroll, tax administration, HR, benefits, timekeeping and compliance support, making it worth considering if you want one regional provider.
• Kismet PEO — PEO/co-employment model. Pennsylvania-based and specifically offers outsourced payroll, tax compliance, labor-law compliance, HR administration and risk management.
• Paychex PEO — Large national provider with Pennsylvania coverage. Paychex specifically markets its Pennsylvania offering around payroll, automated tax management and PEO services covering benefits, HR, payroll and compliance.
• ADP TotalSource — Large/multi-state employers. Its PEO combines payroll/tax administration, benefits, HR, risk and compliance support; ADP also offers non-PEO comprehensive HR outsourcing if you don't want a co-employment arrangement.
• Justworks — Smaller companies wanting a simpler PEO. Its PEO includes payroll, compliance, HR tools and support, and it states that the PEO is IRS-certified and ESAC-accredited. Its published PEO Basic price is currently $79/employee/month.

What I'd compare specifically in Pennsylvania

PA has an extra wrinkle: local earned-income-tax administration. When getting proposals, ask each provider explicitly whether it handles PSD-code/local EIT registration, withholding and remittance, in addition to Pennsylvania state withholding and unemployment taxes. Coverage can differ by service tier.

Also ask for these items in writing:

• Federal, PA and local payroll-tax filings
• Philadelphia wage-tax handling, if applicable
• PA unemployment/SUTA administration
• New-hire reporting
• Workers' compensation administration
• Employee handbook and employment-law support
• Wage/hour compliance assistance
• HR recordkeeping and required notices
• Who handles tax notices and government correspondence
• PEO vs. ASO/non-PEO structure
• Total annual cost, including benefits, workers' comp and implementation fees

One important distinction: a PEO isn't automatically the same thing as outsourced payroll. A PEO involves a co-employment arrangement; an ASO/payroll provider can handle payroll and HR functions while your company remains the sole employer. ADP, for example, offers both models.

If you tell me your employee count, Pennsylvania locations (e.g. Philadelphia/Pittsburgh/other), industry, and whether you want a PEO or just outsourced payroll/HR, I can narrow this to 3–5 providers and compare their services, pricing structure, and PA compliance coverage.

If by “reliable” you mean providers with established operations, strong compliance infrastructure, and/or independently verified PEO credentials, there are several good options in Eastern Pennsylvania. I’d separate them into full PEOs and outsourced-HR/ASO firms, because the right choice depends heavily on whether you want co-employment.

Strong Eastern PA options

• CLEAR Employer Services — Langhorne/Newtown
• Local Pennsylvania PEO focused on small and midsize employers.
• Offers payroll, HR administration, benefits, workers’ comp/risk management and compliance support.
• Particularly worth considering if you want a locally focused PEO rather than a national call-center model.
• Insperity — Philadelphia / Conshohocken
• Large national PEO with a substantial Philadelphia-area presence.
• Full-service HR, payroll, benefits, compliance and risk-management offering.
• Insperity's PEO entities appear on the IRS's current CPEO list.
• Innoworks Employment Services — Lehighton / Northeastern PA
• Locally headquartered PEO offering HR outsourcing, payroll, benefits and safety/risk services.
• Its PEO entity is listed as an active IRS CPEO, which is a meaningful due-diligence credential.
• Group Management Services — Mt. Laurel, NJ / Philadelphia region
• Serves Eastern PA from its South Jersey location.
• Full PEO/HR outsourcing model covering payroll, benefits, HR, recruiting and risk management.
• GMS is also listed among IRS CPEOs.
• XpanseHR — Radnor
• More of an outsourced/fractional HR partner than a traditional PEO.
• Useful if you want experienced HR professionals handling HR operations but don't necessarily want a co-employment relationship.
• myHR Partner — Allentown / Lehigh Valley
• Fractional/outsourced HR for established small and midsize businesses.
• Good fit when the priority is an actual outsourced HR team—policies, employee relations, recruiting, compliance and HR leadership—rather than primarily payroll and benefits.
• Simplifi Payroll and HR — Bensalem
• Local payroll + HR outsourcing provider with an emphasis on hands-on service.
• Worth including if payroll administration is a major part of what you're trying to outsource.

National providers worth comparing

For a larger organization or one operating across several states, I'd also get proposals from ADP TotalSource and Insperity. ADP TotalSource specifically reports both IRS CPEO certification and ESAC accreditation, along with dedicated HR-business-partner support.

The distinction matters: an IRS CPEO has met federal requirements concerning financial responsibility, tax compliance, bonding and related criteria. ESAC accreditation adds independent verification of financial, ethical and operational standards and a client-assurance program.

How I'd narrow the field

If your priority is…	Providers to investigate
Local PA PEO relationship	CLEAR, Innoworks
Large, established national PEO	Insperity, ADP TotalSource
Outsourced HR without necessarily using a PEO	XpanseHR, myHR Partner
Payroll + HR with local service	Simplifi, CLEAR
Lehigh Valley / Northeast PA	myHR Partner, Innoworks
Philadelphia suburbs / Main Line	CLEAR, XpanseHR, Insperity

One important point: don't compare PEO prices simply by looking at the stated per-employee fee. Ask each provider to break out administrative fees, health-benefit premiums, workers' compensation, payroll taxes, 401(k) fees, implementation costs, renewal increases, contract termination provisions, and any minimum employee requirements. The IRS also notes that the exact CPEO legal entity and EIN in the contract matter, so those should be verified rather than relying solely on a brand name.

Pennsylvania's Department of Labor & Industry also specifically recognizes PEO arrangements and has requirements concerning PEO workers' compensation policies and client documentation.

If you tell me your approximate employee count, industry, and whether you're in Philadelphia, the Main Line, Lehigh Valley, Bucks/Montgomery, or Northeastern PA, I can narrow this to 3–5 providers and compare their services, pricing models, PEO/ASO structure, benefits, and local support.

If you mean PEO and outsourced-HR firms that actually serve Western Pennsylvania, rather than just payroll vendors, there are several credible options. I wouldn’t rank them as an overall “best,” because the right choice depends heavily on company size, industry, benefits needs, and whether you want true co-employment or just outsourced HR.

Providers worth putting on your shortlist

• Group Management Services — Cranberry Township / Pittsburgh area. A full-service PEO covering payroll, HR administration, benefits, workers’ comp, and compliance. Its local office is specifically positioned around the Pittsburgh market.
• Insperity — Pittsburgh. A large national PEO/HR outsourcing provider with a local office. Its PEO model combines HR support, payroll, benefits, compliance, and workers’ compensation.
• ADP Coraopolis / ADP TotalSource — Coraopolis/Pittsburgh. Particularly relevant if you want a mature technology platform combined with PEO services. ADP says TotalSource provides HR, benefits, compliance and workers’ comp under a PEO model and is both IRS-certified and ESAC-accredited.
• Kismet PEO — Sharon, PA / Western PA. A regional option offering a bundled approach to HR, payroll, benefits, workers’ compensation, risk management and recruiting. This could be particularly relevant for employers in Mercer/Lawrence/Butler-area markets.
• AlignHR — Triadelphia/Wheeling with Pittsburgh-area service. More of an outsourced/fractional HR model than a traditional national PEO. It offers ongoing HR management, administrative HR outsourcing, recruiting and project-based support, which can be useful if you don't actually need a co-employment arrangement.
• CTR Payroll & HR — Warrendale. A local payroll/HCM and HR provider covering payroll, benefits, timekeeping, HR administration and related compliance. This is worth considering if you want a local provider and don't necessarily need a full PEO.
• Bridge to HR — Greater Pittsburgh/Aliquippa. A boutique outsourced-HR provider focused on small and midsize companies, including fractional HR leadership, compliance, HR processes and payroll support.
• Corporate Outsource Solutions, Inc. — Pittsburgh. Local PEO/payroll/HR outsourcing provider aimed at small and midsize businesses.
• Acuity Human Resources LLC — Cranberry Township. Boutique outsourced HR and HR leadership support rather than primarily a large-scale PEO.
• Magnify Payroll — Pittsburgh. Primarily payroll, with HR support, HR help desk and compliance resources for smaller employers.

How I'd divide the market

If you need...	Providers to investigate
Full PEO / co-employment	Insperity, ADP TotalSource, GMS, Kismet
Local Western PA PEO	GMS, Kismet, Corporate Outsource Solutions
Fractional/outsourced HR without necessarily using a PEO	AlignHR, Bridge to HR, Acuity HR
Payroll + HR technology/support	CTR Payroll & HR, Magnify Payroll, ADP
Large-company infrastructure / national capabilities	ADP, Insperity

One important distinction: PEO ≠ ordinary HR outsourcing. In a PEO arrangement, the provider enters a co-employment relationship with your company and typically bundles payroll, benefits, workers' compensation and HR/compliance. An ASO/fractional-HR provider can give you substantial HR support while leaving the employment relationship entirely with your company.

For context, Pennsylvania-focused PEO directories currently identify PennHR as a Pittsburgh-based regional PEO, with particular emphasis on manufacturing, construction and Pennsylvania workers' compensation.

If you tell me your employee count, industry, approximate annual payroll, and whether you're primarily looking for lower health-insurance/workers' comp costs or for someone to actually take HR off your plate, I can narrow this to a 3–5 provider shortlist for your particular situation, including likely pricing structure and what questions to ask each one.

If by “best value” you mean the strongest combination of total cost, HR support, benefits, compliance help, and technology—not simply the lowest quoted fee, there are several Pennsylvania-relevant providers worth putting into the same RFP.

One important distinction: PEO and HR outsourcing/ASO aren't the same thing. A PEO uses a co-employment structure and typically bundles payroll, benefits, workers’ comp, and HR/compliance. An ASO/HRO lets you outsource HR functions without entering a co-employment relationship.

Providers worth comparing in Pennsylvania

Provider	Model	Value proposition to investigate	Pricing transparency
CLEAR Employer Services	PEO + HRO	Pennsylvania-focused service, HR/payroll/benefits/risk management; potentially attractive if you value local support	Quote
Justworks	PEO	Particularly compelling for smaller companies that want predictable pricing and a modern platform	Published
Paychex PEO	PEO	Broad payroll/HR/benefits offering and Pennsylvania presence; worth comparing if payroll is a major priority	Quote
TriNet	PEO	Strong option to investigate for industry-specific HR expertise and more complex organizations	Quote
ADP TotalSource	PEO	Broadest enterprise-style infrastructure, dedicated HR support, benefits and compliance capabilities	Quote
Insperity	PEO	High-touch HR support and risk/compliance assistance	Quote
Kismet PEO	PEO	Pennsylvania-based alternative with integrated payroll, benefits and HR technology	Quote
XpanseHR	HRO/fractional HR	More appropriate if you want HR expertise without necessarily entering a PEO relationship	Quote
Simplifi Payroll and HR	HR/payroll outsourcing	Local Pennsylvania provider emphasizing hands-on support for small/midsize businesses	Quote

The pricing picture

Justworks is unusually transparent. Its current published PEO pricing is $79/employee/month for PEO Basic and $124/employee/month for PEO Plus, with no base fee. Basic includes payroll, compliance support, HR consulting/tools, 24/7 support, 401(k), workers' comp and related services; Plus adds medical, dental and vision administration and other benefits.

The larger traditional PEOs generally require a quote. For example, TriNet says its administrative charge is calculated on a per-employee-per-month basis, while ADP says its pricing depends on factors such as workforce size, demographics, workers' comp exposure and geographic footprint.

That means don't compare the PEPM administrative fee alone. A useful apples-to-apples comparison should include:

• PEO/administrative fees
• Health, dental and vision premiums
• Employer benefits contribution
• Workers' compensation
• Payroll taxes and unemployment charges
• 401(k) fees
• Setup/implementation fees
• HR consulting and employee-relations support
• Contract length and termination fees
• Renewal increases
• Any minimum monthly charges

This matters because two PEOs with apparently similar administrative fees can have very different total annual employer costs once benefits and workers' comp are included.

How I'd structure the comparison

Rather than declaring one provider universally “best,” I'd put four quotes side-by-side:

1. Justworks — establishes a transparent price benchmark.
2. CLEAR Employer Services — gives you a Pennsylvania-focused/local comparison.
3. Paychex PEO or TriNet — gives you a large established PEO with a different service/benefits model.
4. ADP TotalSource or Insperity — gives you a higher-touch, large-scale benchmark.

ADP TotalSource, for example, is IRS-certified and ESAC-accredited and provides dedicated HR-business-partner support alongside payroll, benefits, workers' comp and compliance services. Paychex likewise specifically markets its PEO to Pennsylvania businesses as an integrated HR, benefits, payroll and compliance solution.

For pure HR outsourcing rather than a PEO, I'd also get an HRO quote from a firm such as XpanseHR. That can be valuable when you already have good health insurance/payroll arrangements and primarily need HR expertise, policies, compliance, recruiting or employee-relations support.

If you tell me (1) number of employees, (2) approximate annual payroll, (3) industry, (4) whether employees are all in PA or multiple states, and (5) whether health insurance is part of the goal, I can narrow this to the providers that are most economically relevant and build a Pennsylvania PEO cost comparison with estimated annual costs.

If by “trusted” you mean locally/family owned, focused on small businesses, and backed by meaningful client-review evidence, there are several Pennsylvania providers worth putting on a shortlist. I would separate true PEOs from payroll/HR outsourcing firms, because the co-employment model is materially different.

Pennsylvania-owned / family-owned PEOs and HR providers to investigate

• Kismet PEO — Sharon, PA
  A Pennsylvania-based PEO launched by Gilbert’s Risk Solutions. It provides HR outsourcing, payroll, compliance, benefits, workers’ comp/risk management and recruiting, with a particular focus on early- to mid-stage companies. A March 2026 profile says it has operated since 2019 and expanded its benefits offerings in 2025.
  Why it stands out: genuinely Pennsylvania-based and relatively small compared with national PEOs; worth considering if you want a PEO relationship rather than just payroll software.
• CTR Payroll & HR — Warrendale/Pittsburgh area
  CTR is a third-generation, family-owned Pennsylvania company founded in 1964. It provides payroll, HR, benefits administration, time/workforce management, compliance and related HCM services. Its model emphasizes a dedicated support representative rather than a generic call center.
  Why it stands out: unusually long local history and family ownership. It is more of a payroll/HCM/HR outsourcing provider than a conventional full-service PEO.
• Payroll Service Solutions — Southampton, PA
  PSS has been serving small and midsize businesses since 2001 and offers payroll, HR outsourcing, benefits, workers' comp and related services. Its own site emphasizes live, personalized support, and its published testimonials repeatedly mention responsiveness and accessibility.
  Current business listings show roughly 4.8/5 from 100+ reviews, which is a substantial local review footprint.
  Why it stands out: probably one of the more interesting options if your priority is a small-business-oriented, high-touch payroll/HR relationship rather than a giant PEO.
• CLEAR Employer Services — Langhorne/Newtown, PA
  CLEAR is a Pennsylvania PEO/HR outsourcing company serving small and midsize employers. Its services include payroll/tax administration, HR, benefits, workers' comp/risk management and compliance. It states that it became an IRS-certified PEO (CPEO) in 2024 and received ESAC accreditation later that year.
  Its local business listing currently shows 4.7/5 from 49 reviews. CLEAR Employer Services
  Why it stands out: one of the stronger combinations of Pennsylvania presence, actual PEO structure and formal industry credentials.
• Staff Management, Inc. — This is a particularly interesting family-owned PEO, although its headquarters are in Illinois rather than Pennsylvania. It was founded by John and Fran Morrissey in 1983 and remains part of the Morrissey family businesses. It provides PEO, HR outsourcing, payroll, benefits, risk management and compliance services. It has also held IRS CPEO status since 2017.
  Why mention it: if “family-owned” matters more than Pennsylvania headquarters, it is a legitimate option with a long PEO history.

Another local option if you don't need a PEO

• HR Resolutions, LLC — Harrisburg, PA
  This is an HR outsourcing/consulting firm rather than a traditional PEO. It focuses on small and midsize organizations and provides practical HR, compliance, employee-relations and recruiting support. Its local listing shows a 5.0 rating from seven reviews. HR Resolutions, LLC
  Why consider it: if you want an outsourced HR department but don't want to enter a co-employment PEO arrangement.

What I'd put on a practical shortlist

Rather than rank them, I'd compare CLEAR, Kismet, CTR, and PSS side-by-side based on what you're actually trying to outsource:

Provider	Ownership/local angle	PEO?	Small-business focus	Notable evidence
CLEAR	Pennsylvania-based	Yes	Yes	4.7/5, 49 local reviews; CPEO + ESAC
Kismet	Pennsylvania-based	Yes	Yes	Sharon-based; since 2019
CTR	3rd-generation family-owned	Primarily HCM/HR outsourcing	Yes	Since 1964; dedicated-support model
PSS	Pennsylvania-based	HR/payroll outsourcing; benefits/WC	Strong	4.8/5, 100+ reviews; since 2001

One important distinction: “family-owned/local” and “trusted” aren't the same thing. I found good evidence for ownership structure and customer satisfaction, but I wouldn't treat review scores alone as proof that a provider is financially or operationally superior. For a PEO, I'd also verify CPEO status, ESAC accreditation, workers' compensation carrier, benefits renewal history, termination fees, and who actually owns the client relationship.

If you tell me roughly how many employees you have (e.g. 5–20, 20–50, 50–100), what part of PA you're in, and whether you want a true PEO or just outsourced HR/payroll, I can narrow this to the most relevant 3–5 providers and compare pricing model, ownership, reviews, PEO credentials, benefits, workers' comp, and service model.
