OnPay Payroll Review 2026: Honest Assessment After Real Use

I've been tracking small business payroll software for about two years, and OnPay is consistently one of the most underrated options in the market. Here's my honest take after seeing it in actual use across several small businesses.

Why OnPay Gets Overlooked

OnPay doesn't have Gusto's marketing budget or ADP's brand recognition. It doesn't show up on the first page of "best payroll software" searches as often as the big names. But when I dug into the actual platform, I found a product that outperforms its profile.

What OnPay Does Well

Pricing simplicity. OnPay charges $40/month base plus $6 per employee. No hidden fees for quarterly filings, W-2s, or year-end processing. For small businesses, this predictability matters.

Tax compliance. OnPay handles all federal, state, and local payroll tax filings automatically. The error rate is low, and the support team actually knows tax compliance—not just the software.

Multi-state payroll. If you have remote employees in multiple states, OnPay handles it without charging per-state fees. This is a meaningful advantage over some competitors.

HR features. The included HR tools—offer letters, PTO tracking, employee onboarding—are genuinely functional, not just checkbox features.

Where It Falls Short

Integrations are more limited than Gusto or Rippling. If you're deeply invested in tools like Salesforce, Lattice, or complex HRIS platforms, you may find integration gaps.

No dedicated HR advisor. If you want access to HR expertise (not just software), you need a different tier or a third-party solution.

Mobile app is functional but not polished. For owners who manage payroll from their phones, it's adequate but not great.

OnPay vs. Gusto

This is the comparison I get asked about most. My take: OnPay wins on pricing and tax handling; Gusto wins on integrations, design, and HR features. For businesses primarily focused on payroll compliance at a reasonable price, OnPay is the better call.

Who Should Use OnPay

OnPay is a strong fit for:

Small businesses with 5-100 employees
Companies with multi-state remote teams
Teams that want full-service payroll without per-feature upcharges
Businesses already using QuickBooks or Xero

It's less ideal for fast-scaling companies that need deep HR tech integrations or dedicated HR support.

The Bottom Line

OnPay consistently delivers on its core promise: accurate, automated payroll at a fair price. It's not the flashiest platform, but it does what small businesses actually need payroll software to do.

If you're evaluating options and haven't looked at OnPay yet, it deserves a spot in your consideration set.
