OnPay Payroll Software

OnPay is a cloud-based payroll software that provides all the payroll functionality and features for small and mid-sized businesses.

The solution helps businesses streamline payroll processes and automate tax filing and payment workflows. Users can easily and quickly enter payroll information (hours, tips, bonuses, etc.). OnPay can also handle benefits such as health insurance and compensation insurance.

Users who can pass the risk assessment conducted by the provider can use the direct deposit feature. Still, all users can pay employees through checks without any tests or inspections.

OnPay can also calculate state and federal taxes, withholding, file tax forms, and even make tax payments. So, again, the solution guarantees accuracy, and the provider will take responsibility if any errors happen in the tax filings.

On the surface, OnPay may look fundamental or more basic than some of its competitors, but the solution can focus 100% on delivering its core services as efficiently as possible. This simplicity also serves to help new users get the most out of the software without being confused by an overcrowded interface with features they may never get to use.

The solution is not free, but it is in the “affordable” price zone, which makes it suitable for small and midsize businesses, and OnPay offers a one-month free trial on all their plans if you think this might be the solution for you.
