I just added the payroll module to my quick books. how can i add prior payroll transactions made outside quick books?

Hi selectwd,

Welcome to the Community. Being able to record prior payroll information is essential to ensure that your employees' payroll information is up to date. QuickBooks Online Payroll is a great program that gives you the ability to pay your employees and track your remittances. I'd be glad to point in the right direction to add prior payroll transactions.
 

If you haven't run payroll in your QuickBooks account, I encourage to review this article to add pay history to QuickBooks Online Payroll.

If you have run any payrolls on your account, I recommend contacting our customer support team. They'll be able to provide you with a Pay Edits template to add prior payroll transactions. You can refer to the following options available to reach out to our team.
