Gusto is the better documented fit for most small businesses under roughly fifty employees because it publishes its prices and bundles payroll, benefits and onboarding into a clean interface, while ADP is the better documented fit for companies that want a large provider with deeper HR services, scalability and a sales-led setup. This comparison of Gusto and ADP (specifically ADP RUN, its small business product) looks at documented pricing, features and the limits of each.
The biggest practical difference is transparency. Gusto lists monthly base fees and per-employee fees on its site, while ADP does not publish RUN prices and quotes based on headcount, pay frequency and state count. That means any ADP figure below is a third-party estimate, and you should get a real quote before deciding. Verify Gusto's current prices too, since sources already disagree on some tiers.
How We Compared Gusto and ADP
We compared the two from each vendor's public product pages, 2026 third-party pricing summaries, and patterns in verified user reviews. We did not run payroll through either service, so nothing here measures accuracy of tax filings or support responsiveness. Where sources disagreed we say so. The yardstick is the same for both: documented pricing at small team sizes, features by tier, multi-state support, HR and benefits options, and what reviewers consistently praise and criticize.
Pricing Compared at Small Team Sizes
Gusto documents tiered plans. Third-party sources report the Simple plan at roughly $40 to $49 a month plus about $6 per employee, limited to single-state payroll. Plus is reported at about $80 a month plus $12 per employee, adding multi-state payroll and time tracking. Premium is reported at about $180 a month plus $22 per employee by one source, while another lists it as custom priced. Contractor-only and add-on options are priced separately.
ADP does not publish RUN prices. Third-party estimates put RUN Essential near $79 a month plus $4 to $5 per employee, one puts a ten-person company near $119 a month before add-ons, and others cite $100 to $300 a month for a typical small business. Time and attendance, HR support and other add-ons are often priced separately. Treat all of this as rough and ask ADP for a written quote.
Features and Plans Side by Side
| Factor | Gusto | ADP RUN |
|---|---|---|
| Published pricing | Yes (verify current) | No, quote-based |
| Typical small team cost | From about $40 to $49 plus about $6 per person | Estimates from about $79 plus $4 to $5 per person |
| Multi-state payroll | Plus tier and above | Documented, varies by plan |
| Benefits administration | Documented, integrated | Documented, broad options |
| HR support | Higher tiers include HR resources | Add-ons and higher tiers |
| Setup style | Self-serve | Sales-led, with service reps |
| Best fit | Small teams wanting simple, transparent payroll | Growing firms wanting scale and HR depth |
Where Gusto Wins
Reviewers consistently praise Gusto's modern, easy interface, clear pricing, quick self-serve setup and employee-facing tools such as onboarding and pay stubs. For a team of a few people to a few dozen, the documented combination of automated tax filings, direct deposit and benefits in one place makes it the common starting point. The weaknesses reviewers report include per-employee costs that rise on higher tiers, add-ons that increase the bill, and support that some find slower on the lower tiers.
Where ADP Wins
ADP is documented as one of the largest payroll providers, with a path from small business to mid-market products, wide HR and compliance services, and options such as time tracking and workers' compensation integrations. Reviewers credit that scale and service depth. The criticisms are also consistent: unpublished pricing, a quote process that can feel sales-heavy, add-ons that can inflate costs, and an interface some describe as older than newer rivals. Read any contract terms carefully, including renewal and cancellation conditions.
Migration, Compliance and Support
Switching payroll providers mid-year is possible but takes care. Both vendors document onboarding help, but you will need to supply year-to-date payroll history so that quarterly filings and year-end forms stay accurate, and the timing around a quarter boundary matters. Neither tool replaces an accountant or tax professional for questions about worker classification or state registration. If you also compare bookkeeping tools, our best accounting software roundup covers how payroll connects to the books, and both providers document integrations with common accounting platforms.
Hidden Costs and Contract Questions
The monthly base fee and per-employee rate are only part of the bill. Ask both vendors what they charge for contractors, for year-end forms, for off-cycle or bonus payrolls, for additional states, and for time tracking or HR add-ons. Reviewers commonly report that the price they paid ended up higher than the first number they were shown, particularly where optional services were bundled into a quote. Ask about setup fees, minimum terms, auto-renewal and the notice period for cancelling, and get the answers in writing.
It also pays to ask how each provider handles errors. Find out what happens if a tax filing is wrong, whether penalties caused by the provider are covered, and how you reach a person when payroll is due the next day. Support quality is one of the most mixed areas in published reviews of both services, so treat it as a question to put to the vendor directly rather than an assumption.
Which One to Choose
Choose Gusto if you want transparent pricing, fast setup and a simple interface for a small team. Choose ADP if you want a large provider with HR depth and are comfortable with a quote-driven process, particularly if you expect to scale or operate in several states. Either way, request a written quote at your real employee count, ask what is included in the base price, and confirm contract length and cancellation terms before you sign.
The bottom line: Gusto is the safer first quote for a small team that values transparent pricing and an easy interface, ADP is worth a quote when HR depth and scale matter more, and you should compare written prices at your real headcount before signing either.
