Gusto vs ADP at a glance
Both file federal, state, and local taxes in all 50 states, both run W-2 and 1099 payroll in one batch, and both take liability for penalties caused by their own automation. The differences are pricing transparency, contracts, and HR depth.
| Factor | Gusto | ADP (RUN) |
|---|---|---|
| Starting price | $49/mo + $6 per person (published) | $49/mo + $6 per person (published) |
| Pricing model | Transparent, published | Custom quote, negotiable |
| Contract | Month to month | Often 36 months with early termination fee |
| Best fit size | 1 to about 50 employees | Small through enterprise (1,000+) |
| Ease of use | Modern, fast setup | Powerful but steeper learning curve |
| Contractor-only plan | Yes, $35/mo + $6 | No dedicated 1099 plan |
| Background checks | Add-on via Checkr | Included on all RUN plans |
| Multi-state payroll | On Plus plan ($80/mo) | On all RUN plans |
Gusto vs ADP pricing compared
Pricing is the clearest difference. Gusto publishes every price and bills month to month. ADP routes buyers through a sales quote and signs most small businesses to a multi-year contract, so the headline number is a floor, not the final cost.
| Plan tier | Gusto | ADP RUN |
|---|---|---|
| Entry | Simple: $49/mo + $6 per person | Essential: approx. $79/mo + $4 per person |
| Mid | Plus: $80/mo + $12 per person (multi-state, time tracking) | Enhanced: quote-based, higher base plus per-person |
| Top | Premium: custom (HR experts, advisor) | Complete and HR Pro: quote-based, HR advisory |
| Contractor only | $35/mo + $6 per contractor | Not offered as a standalone plan |
| Setup fee | None | Often charged |
Real-world cost example: a 10-person company on Gusto Simple runs about $100 per month, while ADP RUN Essential for the same team lands near $119 per month before add-ons. Gusto stays cheaper for small teams. The math shifts around 20 employees, where ADP’s lower per-employee rate starts to offset its higher base, and at 50-plus employees ADP’s per-employee pricing wins. ADP also applies annual price increases, and time tracking, benefits administration, and W-2 or 1099 filing can be add-ons that raise the real total. Confirm any ADP quote against the published Gusto price as leverage.

Where Gusto wins
Gusto is the better choice for most small businesses, and the reasons are concrete. Pricing is published and month to month, so you can budget and leave without a penalty. Setup is fast and the interface is modern enough that owners without payroll experience run their first payroll in minutes. Full-service tax filing, benefits administration, and onboarding tools are included at the entry price rather than locked behind upgrades. The contractor-only plan at $35 per month plus $6 is the cheapest honest option for businesses that pay only 1099 workers. For companies under about 50 employees that value simplicity and predictable cost, Gusto is the default. The main knock is customer support, which some users describe as slow, and reliability that can strain past 50 employees on complex multi-state benefits.
Where ADP wins
ADP is the better choice when scale and complexity outrun what Gusto was built for. It handles union payroll, shift differentials, wage garnishments, multi-entity payroll, and certified payroll that smaller tools cannot. Background checks are included on every RUN plan, the tax compliance engine is best-in-class, and a three-month free trial softens year-one cost. Most importantly, ADP RUN is the on-ramp to ADP Workforce Now for 50 to 1,000 employees and Vantage above that, so a growing company stays on one vendor as it scales. For regulated industries, multi-state operations, businesses crossing 50 employees, or anyone wanting a named HR advisor, ADP’s depth is the point. The trade-offs are pricing opacity, multi-year contracts with early termination fees, a steeper learning curve, and a dated interface compared with Gusto.
Gusto vs ADP: who should choose which
Match the tool to your situation rather than the marketing.
- Choose Gusto if you have 1 to about 50 employees, want published pricing and no contract, value ease of use, or pay only contractors.
- Choose Gusto if you are a startup or small business that wants payroll, benefits, and basic HR in one simple platform without paying for enterprise features.
- Choose ADP if you expect to cross 50 employees, run union or multi-entity payroll, need certified payroll, or operate in a regulated industry.
- Choose ADP if you want a single vendor that scales from small business to enterprise HR with a dedicated advisor.
- The breakeven sits around 20 to 50 employees: below it Gusto usually costs less and is easier, above it ADP’s per-employee pricing and depth pull ahead.

How we compared Gusto and ADP
Whether you frame the search as Gusto vs ADP or ADP vs Gusto, the decision rests on the same factors. We judged both on the factors a buyer actually weighs: total cost over time (base fee, per-employee fee, add-ons, and contract terms), ease of setup and daily use, breadth and depth of payroll and HR features, compliance capability, and how each scales as headcount grows. We treated each platform on its merits for the size of business it targets, rather than declaring a single universal winner, because Gusto and ADP are built for different stages.
Frequently asked questions
Is Gusto or ADP better for small business?
For most small businesses under about 50 employees, Gusto is better: published pricing, month-to-month billing, faster setup, and full-service tax filing at the entry price. ADP is better for larger or fast-growing companies that need deep compliance, union or multi-entity payroll, and a path to enterprise HR. The right answer depends mainly on your size and complexity.
Is Gusto cheaper than ADP?
For small teams, yes. Gusto Simple is $49 per month plus $6 per employee with no setup fee or contract, while ADP RUN Essential starts around $79 per month plus $4 per employee, quote-based, often with a setup fee and multi-year contract. ADP’s lower per-employee rate can win at scale, with the breakeven around 20 to 50 employees.
Does ADP have a contract and Gusto does not?
Generally yes. Gusto bills month to month with no long-term commitment, so you can cancel without penalty. ADP typically signs small businesses to a multi-year contract (often 36 months) with an early termination fee. This contract difference is one of the biggest practical distinctions between the two.
Can Gusto and ADP both handle multi-state payroll?
Yes, both file payroll taxes in all 50 states. With Gusto, multi-state payroll requires the Plus plan at $80 per month, while ADP supports multi-state on all RUN plans. Both take liability for penalties caused by their own tax automation.
Which is easier to use, Gusto or ADP?
Gusto is generally easier. Its modern interface and self-guided setup let owners without payroll experience run payroll quickly. ADP is more powerful but has a steeper learning curve and a more dated interface, which is the trade-off for its greater depth and configurability.
When should I switch from Gusto to ADP?
Consider ADP when you approach 50 employees, start needing union, multi-entity, or certified payroll, enter a regulated industry, or want a single vendor that scales into enterprise HR. ADP RUN upgrades into ADP Workforce Now for 50 to 1,000 employees, making it a natural path for companies outgrowing Gusto.
Does Gusto or ADP include background checks?
ADP includes background checks on all RUN plans, which is unusual since most providers reserve them for higher tiers. Gusto offers background checks as an add-on through its partner Checkr. If background checks on every plan matter to you, that is a point in ADP’s favor.
Is Gusto good for contractors?
Yes. Gusto offers a contractor-only plan at $35 per month plus $6 per contractor with no base fee, which is one of the cheapest honest options for businesses paying only 1099 workers. ADP does not sell a standalone contractor plan, bundling contractor payments into its paid RUN tiers instead.
