🥇 Gusto — best for most small businesses
Easy setup, automated payroll tax filing, employee self-service, benefits, and HR in one system. I'd choose it if you have roughly 1–50 employees and want payroll to be simple. fitsmallbusiness.com

🥈 Rippling — best if you want automation
Better if you want payroll connected to HR, onboarding, time tracking, apps, and IT/device management. tech.co
Rippling
🥉 QuickBooks Payroll — best if you already use QuickBooks
The integration can make accounting and payroll considerably easier. fitsmallbusiness.comtechnologyadvice.com
QuickBooks Payroll
Best value: OnPay
A good choice if you want straightforward payroll without paying for a large HR platform. fitsmallbusiness.comtechnologyadvice.com

Best for scaling: ADP RUN

ADP RUN
If you tell me (1) number of employees, (2) number of states, (3) whether you use QuickBooks, and (4) your approximate monthly payroll budget, I can narrow it down to the best 2–3 options and estimate your monthly cost.
