OnPay and Paychex both process payroll, but they serve very different market segments. OnPay is built for small businesses wanting simplicity and transparent pricing. Paychex is an enterprise-grade platform that scales from 10 to 10,000+ employees. Your team size and growth trajectory determine which is the better fit.
Feature Comparison
| Feature | OnPay | Paychex |
|---|---|---|
| Pricing Model | $40/mo + $6/employee | Quote-based; typically $39-$200+/mo base + per-employee |
| Ideal Company Size | Best for 1-100 employees | 1 to 10,000+ employees |
| Onboarding Process | Self-service with dedicated rep support | White-glove onboarding with implementation team |
| HR Features | Onboarding, PTO, document storage | Recruiting, onboarding, performance, LMS, analytics |
| Benefits Administration | Health, dental, vision, 401(k), workers' comp | Full suite including PEO, retirement, insurance brokerage |
| Compliance Tools | Tax filing, W-2/1099 prep, new hire reporting | Tax filing, ACA reporting, workers' comp, EEOC |
| Customer Support | Dedicated rep + phone, email, chat | Dedicated specialist, phone, chat, knowledge base |
| Contract Terms | Month-to-month, no lock-in | Annual contracts typical; month-to-month on some plans |
OnPay Wins
OnPay wins for small businesses because it delivers excellent payroll at a transparent price without the enterprise complexity and sales-driven pricing of Paychex.
Paychex is a powerful platform, but its quote-based pricing, annual contracts, and overwhelming feature set are overkill for most small businesses. OnPay gives you everything a sub-100-employee company needs at a price you can see upfront, with a dedicated support rep who knows your account. Paychex becomes the better choice once you're past 100+ employees, need a PEO, or require enterprise HR modules like learning management or advanced compliance reporting. But for the typical small business owner running payroll for a team of 5-50, OnPay is the smarter, simpler choice.
