Best Payroll Software for Small Business in 2025
Gusto, ADP, Rippling, or OnPay? A plain-English guide to which payroll platform fits your headcount, budget, and HR needs.
What payroll software actually needs to do
Payroll software has one job that cannot fail: pay your people accurately and on time, and file the right taxes with the right authorities. Everything else — HR features, benefits, time tracking — is secondary.
The second thing that matters is how much you want to do yourself versus how much you want handled for you. Full-service payroll (where the platform files taxes automatically) costs more than self-service but eliminates a significant compliance burden.
Gusto — Best for small business
Starting price: $46/month + $6/employee/month
Gusto is the most loved payroll platform among small businesses, and the reasons are consistent across reviews: it's easy to use, the employee experience is excellent, and it genuinely handles payroll tax complexity automatically.
When you run payroll in Gusto, federal, state, and local taxes are calculated, withheld, and filed automatically. Year-end W-2s and 1099s are prepared and filed without additional cost. The employee portal lets people update their own information, access pay stubs, and view benefits.
Gusto's integrated health benefits brokerage is a standout feature — you can offer medical, dental, and vision through Gusto without needing a separate insurance broker, which is particularly valuable for small businesses that can't access group rates on their own.
Best for: US businesses with 1–100 employees that want full-service payroll with a clean, modern experience.
ADP Run — Best for established businesses and compliance confidence
Starting price: Approximately $79/month + $4/employee/month
ADP processes payroll for 1 in 6 US workers and has been doing it since 1949. The reliability, compliance coverage, and depth of the platform are unmatched. In all 50 states, through all the complexity of multi-state payroll, overtime rules, and garnishments, ADP has seen it before.
ADP Run (the small business product) is less polished than Gusto but more comprehensive. For businesses that prioritise compliance confidence over modern UX, or that operate across multiple states with complex payroll situations, ADP's depth is valuable.
Best for: Businesses with 20+ employees, multi-state operations, or complex payroll situations. Companies that prioritise reliability and compliance over UX.
Rippling — Best for tech-forward teams
Starting price: From $8/user/month (modules priced separately)
Rippling's pitch is that it's not just payroll software — it's a workforce management platform that handles HR, IT, and payroll together. When you add an employee in Rippling, it can automatically provision their laptop, set up their software accounts, add them to payroll, and enrol them in benefits. When you offboard someone, it handles the reverse.
For technology companies and startups that think in systems, Rippling's approach dramatically reduces the administrative overhead of managing a distributed team. Global payroll in 50+ countries makes it the logical choice for companies hiring internationally.
Best for: Tech-forward companies and startups that want payroll as part of a unified workforce platform. Companies with international employees.
OnPay — Best transparent pricing
Starting price: $40/month + $6/employee/month
OnPay's flat-rate pricing includes everything: full-service payroll in all 50 states, unlimited pay runs, W-2 and 1099 filing, HR tools, and basic benefits administration. No add-on fees for features that other platforms charge extra for. US-based customer support is included.
For small businesses that want straightforward full-service payroll without surprises on the invoice, OnPay is consistently the most recommended alternative to Gusto.
Best for: US businesses that want transparent, all-inclusive payroll pricing without negotiating modules.
Justworks — Best for accessing enterprise benefits
Starting price: $59/employee/month
Justworks is a Professional Employer Organisation (PEO) — meaning Justworks co-employs your workforce and gives small businesses access to large-group benefits pricing that they couldn't access on their own. Medical, dental, vision, 401k, and commuter benefits at Fortune 500 rates.
This makes Justworks particularly valuable for startups and small companies that need to compete with larger employers for talent. The trade-off is cost: at $59/employee/month it's significantly more expensive than standalone payroll, and the PEO relationship has legal implications worth understanding.
Best for: Startups and small companies that need competitive benefits to attract talent.
How to choose
Just need payroll, want it simple: Gusto.
Need compliance confidence, complex payroll: ADP Run.
Tech company, want HR+IT+payroll unified: Rippling.
Want transparent flat-rate pricing: OnPay.
Need enterprise-grade benefits for a small team: Justworks.
Tight budget, basic needs: Patriot Software.
The single most important question: do you want full-service (automatic tax filing) or self-service? Full-service costs more but eliminates the risk of tax penalties. For most small businesses, it's worth the extra cost.
