Both charge a flat base fee plus a per-worker add-on — and at their entry tiers, the numbers are identical: $49 base plus $6 a head. The real differences show up in add-ons, HR depth and which industries each is built for.
OnPay and Gusto's entry plans price identically: $49 a month base plus $6 per worker. Choose OnPay if you want to pay only for the specific HR and time-tracking add-ons you actually use, itemized rather than bundled. Choose Gusto if you want more HR features bundled into a single higher-priced tier (Plus or Premium).

Prices in USD from onpay.com and gusto.com, both checked September 23, 2026. OnPay uses “worker,” not “employee” or “person,” on its own pricing page; the structure (flat base plus a per-head add-on) matches Gusto’s Simple plan exactly.
Editorial assessmentBoth are full-service payroll with tax filing included, and both price the same way — a base fee plus a per-head charge — which makes them unusually easy to compare directly.
Gusto bundles more HR features into higher-priced tiers: Plus adds time tracking and next-day direct deposit, Premium adds a dedicated HR resource and compliance alerts. OnPay keeps one core plan and prices HR, time tracking and live HR support as separate, itemized add-ons at similarly structured rates, so you only pay for what you actually turn on.
Both serve general small-business payroll; check each vendor’s industry-specific features (e.g. agricultural, clergy or multi-state complexity) directly, since HelpCompare’s record does not cover every vertical difference.
Payroll history, tax filings and employee records do not transfer automatically between providers — export year-to-date payroll reports and W-2/1099 data before switching, and plan the move around a quarter or year boundary where possible so tax filings stay clean.
