ADP (RUN) vs Gusto

Our take

Gusto if you want published pricing, a modern interface, and setup without a sales call, which is most businesses under 50 people. ADP if you want the anomaly-flagging payroll preview, separation-of-duties permissions, and a processor that's survived every economic cycle since 1949, and you're willing to sit through the quote process to get it. The fraud-control gap is real but narrower than ADP's price premium at small headcounts.

Editorial score7.6/107.5/10

ADP (RUN)

Pros
  • Anomaly flagging at payroll preview catches padded hours and rate edits where they're cheapest to fix, before the money leaves
  • Separation-of-duties permissions are genuinely hard to find in small-business payroll tools
  • It will still exist in ten years, which matters when your payroll history is your fraud evidence
Cons
  • Quote-only pricing with well-documented renewal creep, the sticker price is a starting bid
  • Everything beyond core payroll is an add-on, and the add-ons are where the invoice grows
  • The platform feels its age in places, and support quality varies wildly by rep

Gusto

Pros
  • If you're already using it for payroll, baseline fraud controls come at no extra cost
  • Approval workflows for hours directly address a common small-business fraud pattern
  • Easy to set up without specialized fraud-detection expertise
Cons
  • Not real fraud detection software, no anomaly scoring, no AI-driven pattern detection
  • Doesn't address BEC/email-based payroll diversion at all, that needs a dedicated tool
  • Per-person pricing adds up as headcount grows
