General contractors face HR challenges that most industries don’t: fluctuating crew sizes, multi-state job sites, high workers’ comp exposure, and prevailing wage requirements on government projects. A standard PEO setup won’t cut it. You need a provider that understands construction payroll, can handle certified payroll reporting, and won’t flinch at your experience modification rate.
This list focuses on PEOs with proven track records serving general contractors—whether you’re running residential builds with 15 employees or commercial projects with 80+ crew members across multiple states. We’ve prioritized providers based on workers’ comp expertise, construction-specific compliance support, and real-world pricing structures that make sense for project-based businesses.
1. PEO Metrics
Best for: Contractors who want to compare multiple PEO providers side-by-side before committing
PEO Metrics isn’t a PEO itself—it’s a comparison service that helps you evaluate actual PEO providers with construction-specific filters and transparent pricing data.
Where This Service Shines
Most contractors pick a PEO based on whoever called them first or what their buddy recommended. That’s a costly mistake when you’re dealing with workers’ comp rates that can swing thousands of dollars based on how a provider classifies your crews.
PEO Metrics gives you side-by-side comparisons with actual data on how providers handle construction businesses—workers’ comp experience, certified payroll capabilities, and real pricing structures. No sales pressure, no provider bias.
Key Features
Construction Industry Filters: Compare providers based on their actual experience with general contractors, not generic PEO marketing.
Transparent Pricing Analysis: See the real cost structure before you get locked into a contract with hidden administrative fees.
Workers’ Comp Data: Understand how each provider handles claims, experience mods, and high-risk classifications.
Unbiased Comparisons: They don’t get paid by providers, so recommendations aren’t skewed by commission structures.
Free Service: No cost to get detailed comparisons and decision support.
Best For
Contractors who are shopping for their first PEO, unhappy with their current provider, or coming up on renewal and want to see what else is available. Especially valuable if you’ve got complex workers’ comp situations or multi-state operations where pricing can vary dramatically between providers.
Pricing
Free comparison service. No hidden fees, no obligation to use any specific provider they show you.
2. BBSI (Barrett Business Services)
Best for: Western U.S. contractors who value hands-on, local risk management support
BBSI operates through a branch-based model with risk management consultants who actually visit your job sites.
Where This Provider Shines
BBSI built their business serving construction and trades companies, so they understand the operational realities of running crews. Their branch structure means you get a dedicated risk consultant who knows your business—not a 1-800 number connecting you to whoever’s available.
This matters when you need someone to review a safety program before bidding a commercial job or help you navigate a workers’ comp claim that could affect your experience mod.
Key Features
Branch-Based Risk Consultants: Local professionals who visit your sites and understand regional construction requirements.
Construction-Focused Safety Programs: Pre-built programs designed for general contractors, not generic office templates.
Job Costing Integration: Payroll systems that work with construction accounting software for accurate project tracking.
Western U.S. Strength: Strong presence in California, Oregon, Washington, and surrounding states where they understand local prevailing wage rules.
Best For
Established contractors with 20-80 employees who operate primarily in the Western U.S. and want proactive risk management support. Works well if you value relationships over technology platforms.
Pricing
Custom pricing based on your risk profile, headcount, and services needed. Typically structured as a percentage of payroll with risk-based adjustments.
3. Employers Resource
Best for: High-risk contractors with workers’ comp challenges other PEOs won’t touch
Employers Resource specializes in placing businesses that other PEOs consider too risky—including general contractors with elevated experience mods or recent claims history.
Where This Provider Shines
If you’ve been turned down by other PEOs because of your workers’ comp situation, Employers Resource is often willing to work with you. They understand that a bad year doesn’t define your entire operation.
Their risk management team focuses on getting your safety programs and claims management to a point where you can eventually qualify for better rates—either with them or by going back to traditional insurance markets.
Key Features
High Experience Mod Acceptance: They’ll quote situations where your experience modification rate makes you uninsurable through standard channels.
Construction Specialization: Deep understanding of construction risk profiles and how to manage them effectively.
Risk Management Consulting: Hands-on support to improve your safety record and reduce future claims.
Claims Management: Active involvement in workers’ comp claims to minimize impact on your future rates.
Best For
Contractors who’ve been declined by other PEOs, have experience mods above 1.2, or are coming off a difficult claims year and need coverage while they rebuild their safety record.
Pricing
Custom pricing that reflects your risk level. Often competitive compared to assigned risk pools or high-risk direct insurance options, though not cheap.
4. Oasis (Paychex PEO)
Best for: Contractors handling prevailing wage projects or multi-state expansion
Oasis is Paychex’s PEO division, offering certified payroll capabilities and national infrastructure for contractors operating across state lines.
Where This Provider Shines
If you’re bidding Davis-Bacon jobs or state prevailing wage projects, certified payroll reporting becomes a compliance requirement that can eat up administrative hours. Oasis handles this through their platform rather than requiring manual workarounds.
Their national presence also helps when you’re expanding into new states and need to navigate different workers’ comp requirements, tax registrations, and employment regulations without hiring state-specific HR staff.
Key Features
Certified Payroll Reporting: Built-in functionality for prevailing wage compliance on government contracts.
National Coverage: Established infrastructure in all 50 states for true multi-state operations.
Integrated Time Tracking: Mobile-friendly time collection that works for field crews and feeds directly into payroll.
Paychex Infrastructure: Backed by a large payroll company with established compliance systems and technology investments.
Best For
General contractors with 25-100+ employees who handle government projects requiring certified payroll or operate in multiple states and need consistent HR administration across locations.
Pricing
Percentage of payroll model. Pricing varies based on your risk classification and which services you need, but expect negotiations around their standard rates.
5. TriNet
Best for: Growing contractors expanding into new states who need scalable HR infrastructure
TriNet is a full-service PEO with strong multi-state compliance capabilities and industry-specific HR consultant support.
Where This Provider Shines
TriNet works well for contractors who are scaling up and need HR infrastructure that can grow with them. Their platform handles the complexity of multi-state employment without requiring you to become an expert in every state’s workers’ comp and employment regulations.
They assign industry-specific HR consultants who understand construction business cycles and can help with hiring strategies, employee handbooks tailored to field operations, and benefits structures that help you compete for skilled labor.
Key Features
Multi-State Compliance: Handles employment law variations across states as you expand your geographic footprint.
Industry-Specific Consultants: HR advisors who understand construction operations and seasonal workforce patterns.
Comprehensive Benefits: Access to health insurance and retirement plans that help attract experienced crew members.
Scalable Platform: Technology and service model designed to grow from 20 to 200+ employees without switching systems.
Best For
Contractors with 30-150 employees who are actively growing, expanding into new markets, or struggling to attract skilled labor because their benefits package can’t compete with larger firms.
Pricing
Per-employee-per-month model, typically ranging from $150-$250+ depending on services selected and risk profile. Higher than some competitors but includes comprehensive support.
6. Insperity
Best for: Established contractors who want premium benefits and comprehensive HR support
Insperity positions itself as a premium PEO with strong health insurance options and full-service HR administration.
Where This Provider Shines
Insperity’s health insurance offerings are often better than what mid-sized contractors can negotiate independently. If you’re losing skilled project managers or experienced foremen to larger companies because of benefits, Insperity can level that playing field.
Their HR support goes beyond basic compliance—they’ll help with performance management systems, employee development programs, and organizational structure as you grow. This matters more for established contractors with stable operations than startups still figuring out their business model.
Key Features
Strong Health Insurance: Access to competitive medical, dental, and vision plans that help retain experienced employees.
Full-Service HR: Comprehensive compliance support, employee relations guidance, and policy development.
Performance Management Tools: Systems for tracking employee development and managing crew leaders effectively.
Established Track Record: Decades of experience serving mid-sized businesses with proven service delivery.
Best For
Profitable contractors with 40-100+ employees who want to invest in employee retention through better benefits and need sophisticated HR support for managing a growing workforce.
Pricing
Per-employee-per-month pricing at the premium end of the market. You’re paying for quality benefits and comprehensive service, not looking for the cheapest option.
7. Justworks
Best for: Smaller contractors who want straightforward pricing and simple technology
Justworks offers a modern PEO platform with transparent, flat-rate pricing and easy onboarding.
Where This Provider Shines
Justworks eliminates the pricing opacity that frustrates many contractors. You know exactly what you’re paying per employee each month—no hidden fees, no percentage-of-payroll calculations that balloon when you’re running overtime on a big project.
Their platform is genuinely user-friendly, which matters when you’re trying to onboard new crew members quickly or manage payroll from a job site. Setup is faster than traditional PEOs that require extensive paperwork and multiple implementation calls.
Key Features
Flat Per-Employee Pricing: Predictable monthly costs that don’t fluctuate with payroll variations.
Simple Onboarding: Fast setup process without the typical PEO bureaucracy.
Modern Interface: Clean, intuitive platform that doesn’t require extensive training to use effectively.
Flexible Options: Choose between full PEO service or payroll-only if you don’t need comprehensive HR support.
Best For
Smaller contractors with 10-30 employees who want predictable pricing, value simplicity over extensive hand-holding, and prefer modern software over relationship-heavy service models.
Pricing
$59/employee/month for Basic plan or $109/employee/month for Plus plan with enhanced benefits and compliance support. Transparent pricing published on their website.
8. CoAdvantage
Best for: Southeast contractors who want flexible workers’ comp payment options
CoAdvantage is a regional PEO with strong Southeast market presence and flexible service configurations.
Where This Provider Shines
CoAdvantage offers pay-as-you-go workers’ comp, which helps with cash flow management when your payroll fluctuates project to project. Instead of large upfront premiums or quarterly adjustments, you pay based on actual payroll each pay period.
Their flexible approach also extends to service levels—you can pick which HR services you actually need rather than paying for a comprehensive bundle that includes things you’ll never use. This works well for contractors who have some internal HR capability but need support in specific areas.
Key Features
Pay-As-You-Go Workers’ Comp: Align workers’ comp payments with actual payroll to improve cash flow management.
Flexible Service Configurations: Choose which HR services you need rather than accepting a one-size-fits-all package.
Southeast Regional Strength: Deep understanding of Florida, Georgia, and surrounding state employment regulations.
Risk Management Services: Safety program development and claims management support tailored to construction operations.
Best For
Contractors with 15-75 employees operating primarily in the Southeast who want to avoid large upfront workers’ comp deposits and prefer customizable service levels over comprehensive packages.
Pricing
Custom pricing based on which services you select and your risk profile. Pay-as-you-go workers’ comp structure helps spread costs throughout the year rather than large quarterly payments.
Making the Right Choice
If you’re dealing with a difficult workers’ comp situation—high experience mod, recent claims, or classifications that make you hard to place—start with Employers Resource. They specialize in situations other PEOs avoid.
For smaller operations (10-30 employees) that value simplicity and transparent pricing, Justworks offers straightforward costs and modern technology without the complexity of traditional PEOs.
Contractors handling prevailing wage projects or expanding across multiple states should look closely at Oasis for their certified payroll capabilities and national infrastructure.
Regional considerations matter too. BBSI’s branch-based model works well in the Western U.S., while CoAdvantage’s pay-as-you-go workers’ comp and flexible services make sense for Southeast contractors managing seasonal cash flow.
Here’s what most contractors miss: PEO pricing for construction businesses varies dramatically based on how providers assess your risk, handle your workers’ comp classifications, and structure their fees. A provider quoting 3% of payroll might actually cost more than one quoting 4% once you account for how they classify your crews and what’s included in their base fee.
Before you sign that PEO renewal, make sure you’re not leaving money on the table. Many businesses unknowingly overpay because of bundled fees, hidden administrative markups, and contracts designed to limit flexibility. We give you a clear, side-by-side breakdown of pricing, services, and contract terms—so you can see exactly what you’re paying for and choose the option that truly fits your business.
