Quick verdict
How these two tools differ.
Gusto and OnPay are two of the most popular payroll options for small businesses and contractors. Gusto is the all-in-one play: more hiring tools, PTO, and benefits administration, with tiered plans that add features as you go. OnPay keeps it simple: one main plan, flat base-plus-per-person pricing, and solid payroll and benefits without the complexity.
Gusto wins on breadth—HR tools, contractor self-service, and a modern interface are hard to beat. OnPay wins on clarity: you get predictable pricing, included support, and a short learning curve. Both handle W-2 and 1099 payroll with automatic tax filing; both integrate with QuickBooks and Xero. The choice often comes down to whether you want more features (Gusto) or more simplicity (OnPay).
Pricing is similar at entry—both often start around $40/month base plus per-person fees. OnPay's flat structure can be easier to project; Gusto's tiers let you add time tracking, PTO, and more as you grow. Choose Gusto if you want one platform that can grow with you and don't mind navigating plans. Choose OnPay if you want one straightforward plan and flat pricing.

Pricing comparison
What to expect to pay.
Gusto uses tiered pricing: a base fee (e.g. $40/month on Simple) plus per-person costs. Higher tiers add time tracking, PTO, and more. OnPay uses one main plan with a base fee (often around $40/month) plus a flat per-person rate—no tiers for core payroll. At similar headcounts the total can be close; OnPay is often easier to project because the structure doesn't change. Gusto gives you more features on higher tiers; OnPay keeps pricing simple. Compare total monthly cost at your headcount.
