You need payroll to run on time, tax filings to happen correctly, and benefits administration that doesn’t require a law degree to manage. ADP has been doing this for decades, and for many small businesses, it’s the default choice. The question isn’t whether ADP works—it does—but whether it’s the right fit for your size and budget.
What ADP Actually Costs for Small Businesses
ADP doesn’t publish pricing on their website, which should tell you something about their sales process. Based on what small business owners report paying in 2025-2026, expect to start around $80-$120 per month base fee plus $5-$12 per employee per month for their Run platform, which is aimed at companies with 1-49 employees. That puts a ten-person team somewhere in the $130-$200 per month range depending on which add-ons you need.
The price climbs when you add workers’ comp administration, time tracking, or HR support. Full-service payroll with tax filing is included in the base tier, but if you want actual HR advice from a human, that’s a separate tier. ADP sells this as “RUN Powered by ADP,” and while the branding is confusing, the service is straightforward: they process payroll, file your taxes, and give you a dashboard to manage everything.
Where ADP Delivers and Where It Doesn’t
ADP’s strength is reliability. Payroll runs on schedule. Tax filings happen correctly. If there’s an IRS notice, they handle it. For businesses that have been burned by cheaper payroll providers missing a filing deadline or miscalculating withholdings, that reliability is worth paying for. Their support is also phone-based and available during business hours, which matters if you’re not interested in troubleshooting payroll via chatbot at 9 PM.
The downside is flexibility. ADP’s systems are built for standardization, not customization. If your pay structure is straightforward—hourly or salary, standard benefits, normal PTO—it works great. If you have commission structures, complex bonuses, or unusual pay schedules, you’ll spend time working around the platform’s limitations. The interface also feels dated compared to newer competitors, though it’s functional enough that most users stop noticing after a few payroll cycles.
How ADP Compares to Alternatives
| Platform | Starting Price (10 employees) | Best For |
|---|---|---|
| ADP Run | ~$130-200/month | Reliability, phone support, tax compliance |
| Gusto | ~$40 + $6/employee (~$100/month) | Ease of use, modern interface, benefits integration |
| Paychex Flex | ~$100-180/month | Similar to ADP, slightly lower cost |
| QuickBooks Payroll | ~$45 + $5/employee (~$95/month) | Existing QuickBooks users |
Gusto costs less and offers a cleaner interface, but ADP has deeper experience handling compliance issues across all fifty states. QuickBooks Payroll makes sense if you’re already using QuickBooks for accounting and want everything in one place. Paychex is ADP’s closest competitor in terms of service model and pricing—they’re essentially interchangeable for most small businesses.
Who Should Use ADP
ADP makes sense if you value established infrastructure over cost savings. You’re paying for a company that’s been doing payroll since the 1940s and has seen every edge case. If you’re in a heavily regulated industry, have employees in multiple states, or just want to sleep well knowing payroll won’t be the thing that breaks, ADP delivers that peace of mind. If you’re price-sensitive or want a modern interface, look at Gusto first. [CTA: Try ADP Run]
