ADP TotalSource Review 2026

Enterprise-grade HR for growing mid-market companies

Founded: 1949·Best for: 50–500 employees (sweet spot: 75–200)·Percentage of payroll (typically 2–4%) or PEPM

Our take

ADP TotalSource is a powerhouse for mid-market companies that need enterprise-level HR without building an internal department. Their compliance depth is unmatched and the benefits buying power is genuinely best-in-class. The tradeoff is cost — percentage-of-payroll pricing means your fees grow with every raise you give employees. We always negotiate hard for flat per-employee pricing when working with ADP TotalSource.
