7 Best PEO and Payroll Solutions for General Contractors in 2026

General Contractors-specific PEO context. For general contractors, the PEO vs payroll-only decision is shaped by workers\' comp pool dynamics, industry-specific compliance, and the operational support needed for a general contracting workforce. Payroll-only providers (ADP RUN, Paychex Flex, Gusto solo) handle paycheck processing and tax filing. They don't provide workers' comp coverage, group health insurance, OSHA compliance, or certified payroll automation — all critical for construction.

Top General Contractors HR & Compliance Pain Points

• Subcontractor COI tracking at scale. GCs face liability when subcontractors lack proper insurance. Tracking COIs across 50+ active subs is its own job. Premium PEOs offer COI tracking as part of risk management.
• Multi-state operations on commercial projects. GCs operating across state lines need PEO operational depth in each state — registration, certified payroll, prevailing wage, state-specific labor law.
• Joint employer liability with subs. Recent NLRB and DOL guidance has expanded joint-employer liability between GCs and their subs. PEO compliance teams help structure relationships to limit exposure.
• Project-by-project workers' comp class code variance. Different project types (concrete vs framing vs roofing) carry different workers' comp class codes and rates. PEO administration handles class-code reassignment automatically.

PEO vs Payroll-Only for general contractors

When payroll-only works: A 5–10 person residential construction shop with no federal projects, low mod rate, and existing standalone workers' comp coverage can sometimes work with payroll-only. Rare in construction.

When PEO wins: Almost always. The workers' comp pool dynamics alone usually justify PEO. Add prevailing wage, certified payroll, and OSHA compliance and the case is clear.
