Give employees benefits

Put your team first by offering health insurance or rolling out a low-fee 401(k) plan. It's all synced with payroll. No additional math or deposits necessary.

Take care of HR

Save time! New employees can self-onboard. You can easily manage legal docs, PTO processing, and more.

Simplify your finances

The Xero-OnPay integration is designed to save you time and bring all your accounting together in one place. Once you’re set up, payroll data is automatically added to Xero each time your pay your employees. Our integration gives you a better view of your finances, lets you avoid duplicate data entry, and helps cut down on mistakes.

Do things your way

Your business is unique, so we give you the flexibility to customize how data is added to Xero. For example, you can track wage expenses by Department, Pay Type, or Tracking Categories. This advanced expense tracking lets you set up custom reports in Xero and view your finances in the way that makes the most sense for your business.


Custom account mapping and permissions, plus a client dashboard also make OnPay great for accountants and bookkeepers.
