Group Management Services

What Group Management Services does

Group Management Services (GMS) is a privately held Certified Professional Employer Organization (PEO) founded in 1996 and headquartered in Richfield, Ohio. The company delivers co-employment HR outsourcing to more than 3,500 small and midsize businesses across the United States, covering roughly 50,000 worksite employees through 25 regional offices. GMS targets a long roster of SMB verticals — transportation and logistics, staffing, light manufacturing, construction, janitorial, auto repair, landscaping, home health care, credit unions, technology, machinery, and plumbing/HVAC — where business owners lack dedicated internal HR infrastructure.

GMS's product surface is anchored by GMS Connect, a proprietary HRIS platform that consolidates payroll processing, employee records, benefits administration, time tracking, onboarding, and reporting into a single system, with employee self-service extended to iOS and Android via the GMS Connect mobile application (launched 2021). The commercial stack is organized around two tiers — a Simpler Package (core HR, payroll, risk management) and a Stronger Package (adding 401(k), EPLI, cyber liability, legal services, time clocks) — supplemented by add-on modules priced per employee per month or on a quote basis. Differentiated offerings include the Master Health Plan, which pools the 50,000+ worksite employee base to deliver group health coverage at 21% average premium savings, a Multiple Employer Plan 401(k) administered with Transamerica, telemedicine via Teladoc, an Employee Assistance Program, and integrated risk management spanning workers' compensation, cyber liability, and fleet telematics through OneStep GPS. The platform is certified as a CPEO by the IRS and holds AICPA SOC compliance.

GMS generates revenue primarily through recurring PEPM service fees bundled into the Simpler and Stronger packages, with additional monetization from quoted health insurance administration, workers' compensation premiums, voluntary benefits, and risk management add-ons such as GPS tracking and training services. The go-to-market is sales-led: a direct sales force and dedicated account managers acquire and retain SMB clients, supported by a referral program, content marketing, podcasting, and direct quote request channels. The company has scaled through both organic growth and two disclosed acquisitions — Synergy (February 2021) and Simpeo (January 2023) — and recently appointed a Chief Revenue Officer in March 2026 to drive the next leg of expansion.

Expansion highlights6 records

Broad incumbents

• ADP TotalSource: ADP's TotalSource division is a large, broad PEO offering bundled HR, payroll, benefits, and compliance across the U.S., directly competing with GMS for SMB clients as part of ADP's much larger portfolio.
• Paychex: Paychex is a major incumbent payroll-and-HR-outsourcing provider with a PEO arm serving SMBs; broader portfolio (payroll-only, retirement, insurance) makes it a strong adjacent comparable for GMS's payroll and benefits module.

Direct peers

• Sequoia One: Sequoia is a tech-enabled PEO serving SMB and mid-market customers with similar bundled HR, payroll, benefits, and compliance offerings, providing a comparable digital-native PEO business-model reference point.
• TriNet: TriNet is a PEO specializing in HR solutions for small and midsize businesses, including payroll, benefits, and risk management — directly comparable to GMS's SMB-focused PEO platform.
• Vensure Employer Services: Vensure is a large PEO providing HR outsourcing, payroll, benefits, and risk management to small and mid-sized businesses across multiple verticals — directly comparable in offering, segment, and delivery model.
• Insperity: Insperity (NYSE: NSP) is one of the largest publicly traded PEOs in the U.S., serving SMBs with bundled HR, payroll, benefits, and workers' comp — the most direct comparable to GMS's core offering and segment.
• Asure Software (formerly Oasis Outsourcing / iSystems): Asure operates a PEO franchise (historically Oasis) serving small and mid-market employers with HR, payroll, benefits, and workers' comp — a direct PEO peer with overlapping vertical focus on SMBs.

Emerging players

• Paycor: Paycor provides HR and payroll software for SMBs, including benefits administration and talent management, overlapping meaningfully with GMS's HRIS and payroll modules though without the full co-employment PEO model.
• Rippling: Rippling is a fast-growing HR, payroll, benefits, and IT platform that competes with PEOs in the SMB market by bundling workforce management with software-native delivery — a relevant emerging comparable on product scope and target customer.
• Justworks: Justworks is a tech-enabled PEO offering payroll, benefits, HR, and compliance to SMBs via a modern platform — directly comparable on products and segment, with a more digital-first delivery model that increasingly competes for the same accounts as GMS.
