Overview
Paychex provides payroll and HCM services to approximately 800,000 clients and pays one in 11 U.S. private-sector workers. FY2026 revenue was $6.512B, including $4.868B from Management Solutions, $1.433B from PEO and Insurance Solutions, and $210.9M of rate-sensitive interest on client funds. Its defensible advantages are embedded payroll data and workflows, a sizable human advisory capability, and the operational disruption of replacing a PEO relationship. Suite breadth, ordinary compliance capability, insurance exposure, and client-fund interest are economics of the offering rather than independent moats. The FY2026 10-K was not yet filed and is expected before the end of July; Paycor integration, competition, data and AI regulation, claims costs, and interest rates remain key risks.

Strength
Durability

Erosion risks
- Interest-rate declines reduce yield
- Regulation changes permissible client-fund investments
