30-Second Answer
Choose ADP if you need global payroll (140+ countries), the largest integration marketplace, and a platform that scales from 10 to 10,000+ employees without switching providers. Choose Paychex if you value having a dedicated payroll specialist on every call, need a PEO option for small businesses, or want more transparent pricing. ADP wins 7-5 overall because its broader capabilities and global reach serve more business scenarios.

Frequently Asked Questions
Editor's Take
Here's what I tell every business owner who asks: if you're under 50 employees and US-only, Paychex's dedicated specialist is worth its weight in gold — especially during your first year-end. But the moment you need international payroll or plan to grow past 200 employees, ADP's scalability wins. I've seen too many companies outgrow Paychex and have to do a painful migration to ADP later.
