How We Evaluated

We assessed each payroll platform across seven criteria: ease of payroll processing, tax filing accuracy and automation, benefits administration, employee self-service, compliance support, integration options, and total cost for a 25-employee business. We also weighed customer support quality and the platform’s track record for accuracy.

1. Gusto – Best Overall Payroll for Small Business

Gusto has become the default payroll recommendation for small businesses, and for good reason. The platform combines intuitive payroll processing with benefits administration, HR tools, and compliance support in a single, modern interface that does not require a payroll specialist to operate.

Pricing:

• Simple – $40 per month base plus $6 per employee per month. Includes full-service payroll, employee self-service, and basic hiring tools.
• Plus – $80 per month base plus $12 per employee per month. Adds next-day direct deposit, time tracking, PTO management, and HR resource center.
• Premium – custom pricing with dedicated support, compliance alerts, and HR advisory services.

Key strengths: Gusto automates federal, state, and local tax filings and payments in all 50 states. The platform handles W-2s, 1099s, and new hire reporting automatically. Benefits administration includes health insurance, 401(k), HSA/FSA, commuter benefits, and workers’ compensation, all manageable within the same dashboard. The onboarding flow lets new employees enter their own information, reducing administrative burden. Gusto’s interface is clean and modern, making it accessible to business owners without payroll expertise.

Considerations: Gusto’s Simple plan lacks time tracking and PTO management, pushing most businesses to the Plus plan at a higher cost. The platform is designed for US-based businesses and does not support international payroll. Phone support is only available on the Plus and Premium plans.

Best for: Small businesses with 5 to 100 employees that want a modern, all-in-one payroll and benefits platform with minimal administrative overhead.

2. ADP Run – Best for Established Expertise

ADP is the largest payroll provider in the world, processing payroll for roughly one in six US workers. ADP Run is its small business offering, bringing decades of payroll expertise and compliance knowledge to companies with fewer than 50 employees. For small businesses that want the security of a proven, established provider, ADP Run delivers.

Pricing: ADP does not publicly list pricing. Plans start with Essential Payroll and scale through Enhanced, Complete, and HR Pro tiers. Most small businesses report paying between $60 and $150 per month base plus $4 to $12 per employee per month depending on the tier and features selected. Contact ADP for a customized quote.

Key strengths: ADP’s tax filing engine is backed by decades of experience and a dedicated team of tax specialists. The platform guarantees tax accuracy and handles filings at every level, from federal to state to local, including jurisdictions with complex requirements. ADP’s benefits marketplace offers access to Fortune 500-level benefits packages, including health insurance, retirement plans, and workers’ compensation. The ADP Marketplace connects with hundreds of third-party applications for time tracking, accounting, and HR management.

Considerations: ADP’s pricing is opaque, requiring a sales conversation to get a quote. Total costs tend to be higher than transparent competitors like Gusto or OnPay. The interface, while improved, is not as modern as newer platforms. Some small business owners find the sales process aggressive, with frequent upsells.

Best for: Small businesses that want the reliability of the world’s largest payroll provider with access to enterprise-grade benefits and compliance support.

3. Paychex Flex – Best for Hands-Off Payroll

Paychex Flex combines payroll software with the option for dedicated payroll specialist support. For small business owners who want to offload payroll management entirely, Paychex offers a level of service that purely software-based solutions cannot match.

Pricing: Like ADP, Paychex does not publicly list all pricing. The Essentials plan starts at approximately $39 per month plus $5 per employee per month. Select and Pro plans add HR tools, time tracking, and dedicated support at higher price points. Contact Paychex for a customized quote.

Key strengths: Paychex assigns a dedicated payroll specialist to your account on higher-tier plans. This specialist handles payroll processing, answers compliance questions, and ensures accuracy. The platform supports direct deposit, pay cards, and on-demand pay (allowing employees to access earned wages before payday). Paychex’s compliance engine handles tax filings, wage garnishments, and new hire reporting. The HR administration features include onboarding, employee handbook creation, and performance reviews.

Considerations: Paychex’s pricing can be difficult to predict, and total costs often exceed what small businesses expect after adding features. The interface has improved but still feels less modern than Gusto or Rippling. Some users report inconsistent quality depending on which payroll specialist is assigned to their account.

Best for: Small business owners who want a dedicated payroll expert handling their payroll processing and compliance rather than managing it themselves.

4. Rippling – Best for Unified HR and IT

Rippling is the most technically ambitious platform on this list, unifying payroll, benefits, HR, IT device management, and app management in a single system. If your business wants to manage an employee’s entire lifecycle from a single dashboard, including their laptop, software access, payroll, and benefits, Rippling is uniquely positioned to deliver.

Pricing: Rippling uses modular pricing starting at $8 per user per month for the core platform. Payroll, benefits, and other modules are added at additional cost. Total payroll costs typically range from $12 to $20 per user per month. Contact Rippling for a detailed quote based on your module selection.

Key strengths: Rippling’s automation engine connects payroll changes to downstream systems automatically. When you terminate an employee, Rippling can simultaneously process their final paycheck, deactivate their email account, remote-wipe their company laptop, and remove their access to business applications. The global payroll feature supports employees and contractors in over 50 countries, making it one of the few platforms on this list with international capabilities. The platform’s workflow automation lets you build custom processes for any HR event.

Considerations: Rippling’s modular pricing model makes it difficult to predict costs without a sales conversation. The platform’s breadth means there is more to configure during setup, and the onboarding process takes longer than simpler platforms like Gusto or OnPay. Some small businesses may not need the IT management features and would pay for capabilities they do not use.

Best for: Tech-forward small businesses with 20 or more employees that want a unified platform for payroll, HR, benefits, and IT management, especially those with international team members.

5. OnPay – Best Budget Payroll with Transparent Pricing

OnPay offers a refreshingly simple approach to payroll pricing: one plan at one price with all features included. There are no tiers, no hidden fees, and no features locked behind premium plans. For small businesses that want straightforward payroll without surprises, OnPay is the easiest to budget for.

Pricing:

• Single plan – $40 per month base plus $6 per employee per month. All features included.

Key strengths: OnPay includes full-service payroll with unlimited pay runs, tax filings in all 50 states, multi-state support, W-2 and 1099 processing, benefits administration, onboarding, PTO tracking, and HR tools. Every feature is available to every customer at the same price. The platform processes payroll quickly and accurately, handles tax filings automatically, and provides a clean, easy-to-navigate interface. Customer support is included via phone, email, and chat with no plan restrictions.

Considerations: OnPay lacks some advanced features offered by competitors, including on-demand pay, AI-powered analytics, and an extensive integration marketplace. The platform is US-only with no international payroll support. The interface is functional but basic compared to the more polished experiences of Gusto or Rippling.

Best for: Very small businesses (2 to 25 employees) that want reliable payroll at a predictable price with no feature restrictions or upsells.

Frequently Asked Questions

How much does payroll software cost for a small business?

Most small businesses pay between $40 and $150 per month in base fees plus $4 to $12 per employee per month. For a 10-employee business, total monthly costs typically range from $100 to $270. OnPay and Gusto offer the most transparent pricing, while ADP and Paychex require sales conversations for quotes.

Can I run payroll myself without an accountant?

Yes. Modern payroll software like Gusto and OnPay is designed for business owners without payroll expertise. The platforms calculate wages, withhold taxes, file returns, and generate year-end tax forms automatically. However, consulting an accountant for initial setup and annual reviews is still recommended for compliance confidence.

What happens if payroll software makes a tax filing error?

Most payroll providers offer tax accuracy guarantees. Gusto, ADP, and Paychex will file corrected returns and pay any penalties resulting from their errors. Review each provider’s guarantee terms carefully, as coverage varies. Keeping accurate employee information in the system is your responsibility, and errors from incorrect data entry are typically not covered.

When should a small business switch from manual payroll to software?

As soon as you hire your first employee. Manual payroll is error-prone and time-consuming, and mistakes can result in IRS penalties. Even a solo business with one employee benefits from automated tax calculations and filing. The cost of payroll software is typically less than the cost of a single payroll error penalty.
