Two payroll giants go head-to-head. We break down pricing, features, and which platform fits your business size.
Choosing payroll software is one of the most consequential decisions a growing business makes. Get it wrong and you're dealing with tax penalties, frustrated employees, and hours of manual work every pay period. Gusto and ADP are two of the most popular options on the market, but they serve very different audiences.
Gusto launched in 2012 (originally as ZenPayroll) and quickly became the darling of startups and small businesses. Its modern interface, transparent pricing, and all-in-one approach made payroll feel less like a chore. ADP, on the other hand, has been in the payroll business since 1949. With over 1 million clients worldwide and solutions that scale from 1 to 1,000+ employees, ADP is the incumbent enterprise choice.
In this comparison, we'll examine both platforms across pricing, features, benefits, HR tools, and usability to help you pick the right fit for your business.
Pricing is where these two platforms diverge most sharply, and it often becomes the deciding factor for small businesses.
Gusto offers transparent, published pricing across three tiers:
ADP does not publish pricing. You must request a custom quote, which varies based on company size, features selected, and contract terms. Industry estimates put ADP Run (their small business product) starting around $59/month base + $4/person/month, but actual pricing varies widely. ADP Workforce Now, their mid-market product, typically starts at higher base rates with per-employee fees that can exceed $10/person/month depending on modules selected.
For a 10-person company on basic payroll, expect to pay roughly $100/month with Gusto Simple versus $99-$150/month with ADP Run. At 50 employees, the gap often widens in ADP's favor due to volume discounts that Gusto's fixed per-person pricing doesn't offer.
Both platforms handle the core payroll essentials: calculating pay, withholding taxes, filing returns, and issuing W-2s and 1099s. The differences emerge in the details.
Gusto runs payroll in all 50 states and handles automatic tax filing at federal, state, and local levels. It supports unlimited payroll runs, contractor payments, and multiple pay schedules. Gusto also offers AutoPilot, which automatically runs payroll on schedule if nothing has changed — a genuine time-saver for businesses with salaried employees.
ADP matches all of Gusto's core payroll features and adds several enterprise-grade capabilities. ADP supports global payroll in 140+ countries, making it the clear choice for companies with international employees. ADP's tax engine is battle-tested across decades and handles complex multi-state, multi-jurisdiction scenarios with fewer edge-case issues. ADP also offers garnishment processing, which Gusto handles but with less automation.
Where Gusto shines is speed of setup and flexibility for small teams. You can run your first payroll within minutes of signing up. ADP's implementation typically takes 2-4 weeks and involves a dedicated onboarding specialist — overkill for a 5-person startup, but essential for a 200-person company migrating from another enterprise system.
Benefits administration is a major differentiator and often the reason businesses choose one platform over the other.
Gusto acts as a licensed health insurance broker in most states, meaning you can shop for and enroll in medical, dental, and vision plans directly through the platform. Gusto also offers 401(k) plans (powered by Guideline), HSAs, FSAs, commuter benefits, and life insurance. The enrollment experience is seamless — employees can choose their plans during onboarding and everything syncs automatically with payroll deductions.
ADP offers benefits administration through ADP TotalSource (their PEO product) or through ADP Workforce Now's benefits module. ADP partners with major insurance carriers and gives larger companies more negotiating power on rates. ADP also supports more complex benefits scenarios: COBRA administration, ACA compliance reporting, and multi-tier benefit structures that vary by employee class or location.
For a company with 10-50 employees, Gusto's integrated benefits experience is hard to beat. For companies over 100 employees with complex benefits needs, ADP's depth and carrier relationships become more valuable.
Both platforms have expanded well beyond payroll into broader HR functionality.
Gusto includes offer letter templates, e-signing, new hire reporting, an employee directory, org charts, and basic time-off tracking in all plans. The Plus plan adds time tracking, project tracking, and workforce cost reports. Gusto's compliance features include state tax registration, harassment prevention training (in required states), and poster compliance.
ADP offers a more comprehensive HR suite, particularly at the Workforce Now tier. This includes applicant tracking, performance management, learning management (LMS), compensation planning, and advanced analytics. ADP's compliance tools are more robust, with dedicated compliance specialists, proactive regulatory alerts, and ACA/EEO reporting built in. ADP Workforce Now also integrates with ADP Marketplace, which offers 300+ pre-built integrations with other business tools.
Gusto's HR tools cover 80% of what a small business needs. ADP covers 95%+ but at significantly higher cost and complexity.
New customers get their first 3 months free when they run their first payroll. No credit card required to start.
User experience is where Gusto consistently outperforms ADP, and it's not particularly close.
Gusto was built as a modern web application from the ground up. The interface is clean, intuitive, and genuinely pleasant to use. Running payroll takes 3-5 clicks. Adding a new employee is a guided workflow that takes under 5 minutes. The employee self-service portal is equally polished — employees can view pay stubs, update banking info, access tax documents, and manage their benefits without calling HR.
ADP has improved its interface significantly in recent years, but its enterprise DNA still shows. Navigation can feel labyrinthine, especially in Workforce Now. Features are spread across multiple modules, each with their own interface conventions. The mobile app has improved but still feels clunky compared to Gusto's. That said, ADP's depth means power users who invest time learning the system can accomplish far more complex tasks.
For the small business owner who wants to spend as little time as possible on payroll, Gusto's simplicity is a genuine competitive advantage. For HR professionals who live in the platform daily, ADP's depth becomes an asset rather than a liability.
Company size is the single best predictor of which platform will serve you better.
1-25 employees: Gusto is the clear winner. The transparent pricing, fast setup, integrated benefits, and modern interface make it the obvious choice for very small businesses. ADP is overkill at this size.
25-75 employees: This is the competitive zone. Gusto's Plus plan handles this size well, but growing pains start to appear — limited reporting, fewer integrations, and less customization. ADP Run or the lower tiers of Workforce Now become compelling options, especially if you need multi-state compliance or complex benefits structures.
75-250 employees: ADP takes the lead. At this size, you need robust reporting, dedicated support, advanced compliance tools, and the ability to customize workflows. ADP Workforce Now is purpose-built for this segment.
250+ employees: ADP is the default choice. Gusto's Premium plan can technically handle larger companies, but ADP's enterprise features, global capabilities, and dedicated service teams make it the stronger platform at scale.
Gusto and ADP are both excellent payroll platforms, but they're built for different stages of business growth.
Choose Gusto if: You have fewer than 50 employees, want transparent pricing, value ease of use over depth of features, and prefer a modern self-service experience. Gusto is also the better choice if you want integrated health insurance brokerage without dealing with a separate benefits broker.
Choose ADP if: You have 75+ employees (or plan to grow there soon), need multi-country payroll, require advanced compliance and reporting, or want a platform that can scale with you from 50 to 5,000 employees without migration. ADP is also the right choice if you need a PEO arrangement through ADP TotalSource.
For most small businesses reading this comparison, Gusto delivers the best value. Its pricing is fair, its interface is a joy to use, and its feature set covers everything a growing company needs through the first 50-75 hires. When you outgrow Gusto — and you'll know when you do — ADP will be ready.
