How would I add to the regular payment a lump sum payment along with the regular pay

Hi there, 

Welcome to the Community. QuickBooks offers a flexible payroll module that helps you pay your staff with ease. I'll be glad to provide more info so you're on the right track. 

In order to accomplish your goal in QuickBooks,  I recommend running a bonus cheque. I encourage you to check out this helpful article that shows you: How to create a bonus paycheque. You're welcome to ask other questions. Otherwise, for methods that go beyond the bonus cheque, I recommend consulting with your accountant for expert advice. 

In the meantime, feel free to ask other questions in the comments below. I'll be on standby.
