This comparison is really a question about your next five years, not just your next payroll run. Gusto is the modern, transparent favorite built for small businesses that want to run payroll themselves in a few clicks. ADP is the enterprise incumbent built to scale from your first hire to your thousandth, with the support and compliance muscle to match. Pick wrong and you either outgrow your tool or overpay for capacity you'll never use.

Here's how they compare on the things that actually decide it — price, usability, and how well each grows with you — based on Gusto's published rates, ADP's reported estimates, and the patterns in user reviews.

Pricing: Gusto is transparent; ADP makes you ask

The clearest difference is one you hit before signing up. Gusto publishes its prices: Simple at $49/month + $6 per employee, Plus at $80 + $12, Premium at $180 + $22. You can budget to the dollar.

ADP doesn't list prices at all — every quote comes from a sales conversation. Reported estimates put RUN's entry tier around $79/month + ~$4 per employee, but real-world all-in costs for small businesses commonly land $100–$300/month once features and add-ons stack up. ADP is also more likely to charge separately for extras like year-end W-2 processing and setup.

For a small business, Gusto is almost always cheaper and far easier to predict. ADP's pricing only starts to make sense when scale and complexity justify the premium.

Ease of use: Gusto is built for you to do it yourself

Per the consensus across user reviews, Gusto is the easier platform by a wide margin. It's designed for an owner or office manager to run payroll unassisted — clean interface, plain-language steps, automatic tax filing in all 50 states. Onboarding employees and contractors is largely self-service.

ADP is more powerful but more complex, and that complexity is usually navigated with the help of an assigned representative. That hands-on support is a genuine benefit for businesses that want someone to call — but it also reflects a system that's harder to operate solo.

Scalability: ADP's home turf

This is where ADP earns its reputation. It scales seamlessly from a few employees on RUN up to thousands on Workforce Now, with the compliance depth, multi-state and multi-entity handling, and HR services that large or fast-growing organizations need. Reviews consistently cite its robustness and support as the reason bigger companies choose it.

Gusto scales well for small and growing teams — it comfortably serves businesses into the dozens of employees and offers benefits, time tracking, and basic HR — but it's purpose-built for the small-business segment rather than the enterprise.

Which should you choose?

• Choose Gusto if you're a small business that wants transparent pricing, a tool you can run yourself, and full-service payroll without a sales call. For the large majority of small businesses, it's the better fit.
• Choose ADP if you're scaling quickly, have complex or multi-entity payroll, or want a heavyweight provider with a dedicated rep — and you're prepared to pay for it.
