The quick answer
Use Gusto if you want the best dedicated payroll and HR platform for small businesses and you are not locked into QuickBooks. Use QuickBooks Payroll if you already use QuickBooks for accounting and want everything in one place. Use ADP if you are growing toward 25+ employees and need a platform that scales with enterprise-level compliance support.
Side-by-side breakdown
Gusto starts at $40/month plus $6/person. It handles payroll, benefits, onboarding, PTO tracking, W-2 and 1099 filing, and new hire reporting in all 50 states. The interface is the cleanest of the three and its HR features (offer letters, org charts, document signing) are included at no extra cost.
QuickBooks Payroll starts at $45/month plus $5/person. Its key advantage is seamless sync with QuickBooks accounting — payroll entries post automatically to your books. If you use QuickBooks Online, the combined workflow saves significant time at month end.
ADP is the enterprise payroll provider that also offers small business plans (ADP Run, starting around $59/month). It has the deepest compliance infrastructure, 24/7 support, and handles the most complex multi-state and benefits scenarios. Its interface is less polished but its reliability track record is unmatched.
When to choose Gusto
Gusto is the right choice for most small businesses — especially those under 50 employees who want payroll and HR in one place without enterprise pricing. Its employee self-service portal, benefits administration, and onboarding features go well beyond what you get from QuickBooks Payroll.
When to choose QuickBooks Payroll
Choose QuickBooks Payroll if you already use QuickBooks Online for accounting and the automatic journal entry sync matters to you. The combined QuickBooks ecosystem is powerful for bookkeeping-forward businesses where payroll accuracy hitting the books instantly saves your accountant time.
When to choose ADP
ADP is worth the premium when you are approaching 25+ employees, operate in multiple states with complex benefit plan requirements, or need dedicated HR support available around the clock. Its compliance team and risk management resources are the strongest in the market.
The verdict
Under 25 employees and not locked into QuickBooks: Gusto. Using QuickBooks Online: QuickBooks Payroll. Growing toward 25+ employees or operating in complex multi-state scenarios: ADP Run.

FREQUENTLY ASKED QUESTIONS
Does Gusto file payroll taxes automatically?
Yes. Gusto calculates, withholds, and remits federal and state payroll taxes automatically. It also files W-2s at year end and handles new hire reporting in all 50 states.
Can I switch payroll providers mid-year?
Yes, but it is complex. You will need to transfer year-to-date payroll data to the new provider so W-2s are accurate. Most providers have migration guides. Switching at the start of a new quarter reduces the complexity.
What is the penalty for late payroll tax deposits?
IRS failure-to-deposit penalties range from 2% to 15% of the unpaid amount depending on how late the deposit is. Even one business day late can trigger a penalty. Automated payroll systems prevent this by depositing taxes on the same day payroll is processed.
