Real Friction Points
Manually researched issues reported by actual users. Not AI-generated.
Gusto
Gusto's Simple plan ($49/mo) only supports single-state payroll — multi-state requires the Plus plan at $80/mo. Users on Trustpilot report direct deposits not arriving by the promised 5 PM deadline, 401k payroll errors in 2025 that took months to resolve, and difficulty canceling accounts while charges continue.
ADP RUN
ADP uses opaque quote-based pricing that users say results in hidden fees and bills 2-3x higher than expected. The BBB shows 900+ complaints in 3 years with a 1.06/5 rating. Users report W-2s processed incorrectly, being on hold for 2+ hours, and receiving tax penalty notices from day one of signing up.
The Verdict
Gusto is the clear winner for small businesses under 50 employees that want transparent pricing, modern UX, and fast self-service setup. ADP is the legacy choice for businesses that need multi-state payroll from day one, a full HRIS suite, or plan to scale past 100+ employees where ADP Workforce Now kicks in. Be prepared for opaque pricing and long hold times with ADP.
