ADP vs Paycom

The verdict at a glance

ADP scores higher overall (84 to 73), but the right pick depends on what you weight.

ADP. ADP in 2026: RUN for small teams, Workforce Now for mid-market, Lyric HCM for enterprise. Unmatched tax and compliance depth, opaque negotiated pricing, and real shipped AI agents that stay inside ADP's walls.

Paycom. Paycom puts payroll, HR, time, and benefits on one database and has employees verify their own checks in Beti before payday. Powerful for close and audit; opaque pricing and a closed API are the tradeoffs.
