ADP Review
Enterprise payroll and HR for complex US businesses. Best for: Mid-market and enterprise companies (50–10,000+ employees) with complex multi-state payroll.
ADP is the payroll industry's incumbent — 70+ years of US payroll processing, rock-solid tax compliance, and the most comprehensive handling of complex payroll scenarios (union rules, certified payroll, prevailing wage). The trade-off is significant: pricing requires a custom quote, the interface lags behind modern tools by years, and reported costs run 2–3x Gusto for small businesses with equivalent needs. Best for companies 50+ employees with complex payroll. Gusto is almost always better value for smaller teams.
Our Verdict
ADP earns its reputation on reliability and compliance depth. Its tax filing infrastructure is battle-tested across decades and handles scenarios competitors don't support: certified payroll for government contractors, Davis-Bacon Act compliance, complex union agreements, and tipped employee calculations. For companies with 100+ employees, multiple states, hourly workers, and dedicated payroll staff — ADP's feature breadth is hard to match. Below that threshold, the cost and UX penalty is real: Reddit's r/smallbusiness consistently shows ADP quotes running $200–$300/month for teams where Gusto costs $100–$150. For under 50 employees with standard payroll needs, ADP is more platform than most companies need at a price that's difficult to justify.
Score Breakdown
Pros & Cons
✓What We Like
- ✓70+ years of US payroll processing — tax filing accuracy is industry-leading
- ✓Handles complex payroll: union rules, prevailing wage, certified payroll, tipped employees
- ✓Tax penalty protection: ADP covers penalties if it files incorrectly
- ✓Full benefits administration — health insurance, 401k, COBRA managed in one place
- ✓Time and attendance with shift scheduling (stronger than Gusto for hourly workers)
- ✓Dedicated payroll specialist assigned to your account on higher tiers
- ✓Scales from 1 to 100,000+ employees without a platform change
✗What We Don't Like
- ✗No published pricing — custom quote required, small businesses pay premium rates
- ✗No free trial — demo only, then you're in an annual contract
- ✗Interface is significantly dated — years behind Gusto, BambooHR, and Rippling on UX
- ✗Notorious for upselling: time tracking, learning, and benefits are each separate module quotes
- ✗Customer support quality varies dramatically by representative
- ✗Annual contracts with early termination fees — switching mid-year is expensive
- ✗RUN (small business product) has fewer features than competitors at similar price points
Payroll
ADP's payroll processing is the most battle-tested in the industry. Automatic federal, state, and local tax calculation, withholding, and filing with every pay run — W-2s, 1099s, and year-end reporting included. Multi-state payroll across all 50 states is standard. For complex scenarios — certified payroll for government contractors, prevailing wage, union agreements, tipped employees — ADP handles these natively where many competitors require workarounds. Tax penalty protection is included: if ADP makes a filing error, it covers the penalty and interest up to specified limits on higher tiers.
HR Features
ADP's HR depth depends heavily on the product tier. ADP RUN (the small business product) includes basic HR: digital I-9 and W-4 collection, a document vault, and an employee self-service portal. Higher tiers add recruiting, learning management, and performance management. ADP Workforce Now (the mid-market and enterprise product) adds workforce analytics, succession planning, and compensation management. Small businesses buying ADP for payroll often find HR features thin at the RUN level.
Pricing
ADP does not publish pricing publicly. RUN (for small businesses) requires a custom quote — user-reported prices from r/smallbusiness range from $79–$200/month for base plans plus $4–$8/person/month. Add-ons for time tracking, benefits administration, and HR advisory services are priced separately. Annual contracts are standard. ADP's pricing rewards companies buying multiple modules at scale, making it cost-effective for enterprise but expensive for small businesses buying payroll only.

Frequently Asked Questions
ADP RUN is built for small businesses (typically 1–49 employees) with a focus on straightforward US payroll. ADP Workforce Now is the mid-market and enterprise product for 50–10,000+ employees with full HRIS, advanced analytics, and more extensive HR features. Both require custom quotes. If you're evaluating ADP as a small business, you're looking at RUN — which has fewer HR features than Workforce Now and is less competitive against Gusto than the enterprise product.
