Quick Comparison Table

Pricing Comparison

Gusto Pricing (2026)

Gusto’s pricing is fully transparent and published on its website. No quotes or contracts are required. Monthly billing with no long-term commitment means businesses can cancel anytime. The Simple plan covers core payroll needs, Plus adds time tracking and hiring tools, and Premium provides dedicated HR support.

ADP Run Pricing (2026)

ADP Run pricing varies based on state, pay frequency, and business configuration. The prices above represent typical ranges, but actual costs require a custom quote. ADP may require an annual contract depending on the plan and business type. The per-employee cost is lower than Gusto’s, but the base price is higher.

Paychex Pricing (2026)

Paychex requires custom quotes for all plans. The Essentials plan has a published starting price, but actual costs depend on business configuration, state requirements, and selected add-ons. Contracts are typically required for the Select and Enterprise tiers.

Winner: Gusto for pricing transparency and predictability. ADP and Paychex both require custom quotes, making it harder to compare costs upfront. For businesses with fewer than 10 employees, Gusto’s total cost is competitive despite the higher per-employee rate.

Features Comparison

Core Payroll Processing

Gusto offers unlimited payroll runs on all plans, supporting weekly, biweekly, semimonthly, and monthly pay schedules. Processing takes a few clicks, and Gusto automatically calculates wages, taxes, deductions, and reimbursements. Direct deposit typically takes two business days, with next-day deposit available on the Plus plan and same-day on Premium.

ADP Run processes payroll with direct deposit, check printing, and paycard options. The platform supports multiple pay schedules and automates wage calculations, tax withholdings, and deductions. ADP’s processing is reliable and handles complex pay structures well, including shift differentials, commissions, and piece-rate calculations.

Paychex handles payroll processing with flexibility for various pay structures, schedules, and deduction types. The platform supports direct deposit, checks, and paycards. Paychex’s strength is handling complex scenarios like multi-state employees, garnishments, and prevailing wage requirements.

Winner: Tie. All three handle core payroll processing competently. Gusto is the easiest to use, while ADP and Paychex handle edge cases and complex structures better.

Tax Compliance

Gusto provides full-service tax filing in all 50 states, including local taxes. The platform automatically calculates, files, and pays federal, state, and local payroll taxes. Gusto monitors regulatory changes and updates its system accordingly. Year-end W-2 and 1099 forms are generated and filed automatically. Gusto covers tax penalties resulting from its own errors.

ADP Run offers comprehensive tax compliance across all jurisdictions. ADP’s size and scale give it a deep tax compliance team that monitors federal, state, and local regulations. The platform handles multi-state tax calculations, reciprocity agreements, and local tax requirements. ADP’s tax guarantee covers penalties from its calculation or filing errors.

Paychex provides full tax compliance services including calculations, filings, and payments at all levels. Paychex monitors tax law changes and updates automatically. The platform handles complex tax scenarios including multi-state employment, local taxes, and industry-specific requirements. Paychex also offers tax penalty protection.

Winner: ADP for the most comprehensive tax compliance infrastructure, particularly for businesses with multi-state operations. Gusto and Paychex are excellent for single-state businesses.

Benefits Administration

Gusto includes benefits administration in its core service without additional cost for plan management. Gusto supports health insurance, dental, vision, 401(k), HSA, FSA, commuter benefits, and life insurance. In many states, Gusto acts as a benefits broker, helping businesses find and compare plans. Open enrollment management and automatic deductions are built in.

ADP Run offers benefits administration as an add-on feature. ADP supports health insurance, 401(k), and flexible spending accounts through its benefits platform. The integration with ADP’s broader HR services means benefits scale well, but additional costs apply for administration services.

Paychex provides comprehensive benefits administration as part of its full-service offering. Paychex supports health, dental, vision, 401(k), HSA, FSA, life insurance, and fringe benefits. Paychex acts as a benefits broker and provides dedicated support for plan selection, enrollment, and ongoing management. Benefits administration is one of Paychex’s strongest differentiators.

Winner: Gusto for small businesses (benefits included without add-on fees), Paychex for larger businesses with complex benefits needs.

HR Tools

Gusto provides solid HR tools including employee onboarding, document management, time-off tracking, org charts, and performance review templates. The Premium plan adds access to certified HR advisors and custom workflow support. Gusto’s HR tools are practical and well-designed for small businesses.

ADP Run offers HR compliance tools including employee handbook templates, labor law posters, job description templates, and compliance alerts. The Enhanced and Complete plans add hiring tools (zipRecruiter integration, background checks) and more comprehensive HR support. ADP’s HR tools are compliance-focused rather than strategic.

Paychex provides the most comprehensive HR tools among the three. Services include employee onboarding, handbook creation, compliance management, risk assessment, training resources, and a dedicated HR representative on higher-tier plans. Paychex effectively functions as a part-time HR department for businesses that lack internal HR staff.

Winner: Paychex for the most comprehensive HR services, which is one of its primary differentiators.

Scalability

Gusto

Gusto is optimized for businesses with 1 to 100 employees. Beyond 100 employees, Gusto’s feature set becomes less competitive compared to enterprise-grade solutions. The platform handles basic complexity well (multiple pay rates, contractors alongside employees) but may struggle with highly complex organizational structures, multiple EINs, or international operations.

ADP Run

ADP Run is designed for 1 to 49 employees, but the key advantage is the seamless transition to ADP Workforce Now for mid-market businesses (50-999 employees) and ADP Vantage for enterprise (1,000+). This upgrade path means businesses can start with ADP Run and scale within the ADP ecosystem without changing providers. For growing businesses, this is a significant advantage.

Paychex

Paychex Flex scales from small businesses to enterprise organizations. The platform handles single-employee startups to companies with thousands of workers. Paychex’s comprehensive service model means businesses can add HR services, retirement plans, and insurance as they grow, all within the Paychex ecosystem.

Winner: ADP and Paychex (tie) for scalability. Both offer seamless upgrade paths within their ecosystems. Gusto is the best choice for small businesses that do not anticipate rapid scaling beyond 100 employees.

Support Quality

Gusto

Gusto provides support via email, live chat, and phone during business hours. Support quality is generally good, with knowledgeable representatives who understand both payroll and benefits. The Premium plan offers priority support with faster response times and access to certified HR advisors. There is no dedicated representative model — support is handled by a shared team.

ADP Run

ADP assigns a dedicated support representative to each client. This means businesses work with the same person for questions, issues, and account management. ADP’s support team is known for reliability, and the dedicated rep model ensures familiarity with the client’s specific configuration. Phone support is available during extended business hours.

Paychex

Paychex also provides a dedicated support representative, plus access to a local Paychex office in many markets. This local presence means businesses can often meet their representative in person. Paychex support covers payroll, benefits, HR compliance, and risk management. The combination of a dedicated rep and local office presence is unique among the three providers.

Winner: Paychex for dedicated support with local office presence. ADP is a close second with dedicated representatives. Gusto provides good support but lacks the personal relationship model.

Winner by Business Size and Industry

For Businesses with 1-10 Employees

Gusto is the clear winner. Its transparent pricing, modern interface, and built-in benefits administration provide the best value for small teams. The monthly cost for 10 employees on the Simple plan is $100/mo, which is competitive with ADP and lower than Paychex for comparable features.

For Businesses with 10-50 Employees

ADP Run becomes competitive in this range. The lower per-employee cost ($4 vs. Gusto’s $6) starts to offset the higher base price. ADP’s tax compliance infrastructure also becomes more valuable as complexity increases with more employees across different tax situations.

For Businesses with 50+ Employees

Paychex or ADP are better choices for businesses exceeding 50 employees. Gusto can handle this range, but the lack of dedicated support and limited scalability become more apparent. ADP’s seamless transition to Workforce Now and Paychex’s comprehensive HR services provide better value at scale.

For Restaurants and Hospitality

Gusto offers good tip reporting and FICA tip credit handling, but Paychex has more specialized features for the hospitality industry including tip pooling, shift differential calculations, and industry-specific compliance support.

For Construction and Field Services

ADP Run or Paychex are better suited for construction businesses due to their handling of prevailing wage requirements, certified payroll reporting, union deductions, and multi-state job site compliance.

For Nonprofits

Gusto handles nonprofit payroll well with its user-friendly interface and benefits administration. Paychex offers specialized nonprofit services including 403(b) retirement plan support and tax-exempt organization compliance.

Frequently Asked Questions

Which payroll service is cheapest for small businesses?

OnPay (not covered in this comparison) and Gusto offer the best value for very small businesses. Gusto’s Simple plan costs $40/mo plus $6/employee, totaling $100/mo for a 10-person team. ADP Run Essential costs approximately $99/mo for the same team. Paychex Flex Essentials starts around $115/mo for 10 employees. Pricing varies based on state and configuration.

Can I switch from Gusto to ADP or Paychex?

Yes, switching between payroll providers is common and supported. The receiving provider will need year-to-date payroll data, employee information, and tax filing history. Most providers offer migration support to facilitate the transition. The best time to switch is at the beginning of a quarter or calendar year to minimize tax reconciliation complexity.

Does ADP offer a dedicated representative?

Yes, ADP Run assigns a dedicated support representative to each client. This representative handles questions, issues, and account management. Having a single point of contact who is familiar with the business’s specific payroll configuration is one of ADP’s key advantages over Gusto, which uses a shared support team model.

Which service handles multi-state payroll best?

ADP and Paychex both excel at multi-state payroll due to their enterprise-grade tax compliance infrastructure. Both handle state reciprocity agreements, local taxes, and multi-state employee situations. Gusto also covers all 50 states but may be less efficient for businesses with employees spread across many jurisdictions.

Do these services handle 1099 contractors?

All three services handle 1099 contractor payments alongside W-2 employee payroll. Contractors can be set up with their own payment schedules, and year-end 1099 forms are generated automatically. Gusto, ADP, and Paychex all support mixing contractors and employees in the same payroll system.

Is there a contract required?

Gusto does not require a contract and bills month-to-month. ADP Run may require an annual contract depending on the plan and business configuration. Paychex typically requires a contract for its Select and Enterprise tiers. For businesses that value flexibility, Gusto’s no-contract model is advantageous.

Which payroll service has the best mobile app?

Gusto and ADP both offer well-designed mobile apps. Gusto’s app allows employers to run payroll, view team details, and manage benefits from a mobile device. ADP’s mobile app supports payroll processing, time entry, and employee self-service. Paychex Flex mobile app provides payroll processing and employee self-service features. All three apps support employee access to pay stubs and tax documents.

How long does it take to set up a payroll service?

Gusto typically takes 1-2 business days to set up for a small business. The onboarding process is guided and requires entering company information, employee details, and tax elections. ADP Run setup usually takes 1-2 weeks due to the custom configuration process. Paychex setup also takes 1-2 weeks, with a dedicated representative guiding the process. For businesses that need payroll running immediately, Gusto is the fastest option.
