"The accountant dashboard is a game-changer. I can switch between my clients instantly and the QBO integration is flawless. It has genuinely made offering payroll services profitable for my firm."

Sarah K., CPA · June 2026

"OnPay's support is top-notch. They helped me migrate a dozen clients and the process was surprisingly smooth. The all-inclusive pricing means no surprise bills for tax filings."

David M., Bookkeeper · May 2026

"It's excellent for core payroll for our SMB clients. However, the HR tools are quite basic. We still need a separate HRIS for clients with more complex needs, so it's not a true all-in-one for everyone."

Maria R., Accounting Firm Owner · April 2026

"The peace of mind from their automated tax filings is invaluable. They handle all the state and local nuances, which saves me hours of research and potential client penalties."

Comparison

How it compares

OnPay vs. Gusto: Both are top choices for accountants. Pick OnPay for its straightforward, all-in-one pricing and a slightly more streamlined interface for pure payroll processing across many clients. Choose Gusto if your clients need more robust, integrated HR features like performance management and detailed onboarding tools, and you're willing to navigate a tiered pricing model where costs can increase for more advanced functionalities. OnPay is arguably more direct for firms focused on scaling a core payroll service.

Your clients have complex international payroll needs.

You require an advanced, standalone Human Resource Information System (HRIS).

You primarily serve clients outside of the United States.

In-Depth Overview

For accounting, bookkeeping, and tax professionals, OnPay centralizes client payroll management. The platform provides a dedicated partner dashboard, allowing you to switch between client accounts without logging in and out. This saves significant administrative time, especially when managing a large client roster.

It integrates directly with major accounting software like QuickBooks and Xero, ensuring that payroll data flows seamlessly into the general ledger, which eliminates manual data entry and reconciliation tasks.
