My Employees have duplicated when I moved from desktop to online

Hello there, user02064,

You'll want to delete the duplicate employee detail. Sometimes the migration duplicates the information.

If you're using our QuickBooks Online Standard Payroll, kindly follow these steps:

1. Go to Employees menu.
2. Select the employee name to go to the Employee's profile page.
3. Click the Actions drop-down arrow.
4. Select Delete.

If you're using PaySuite, you can check out this article for the detailed steps: Managing an employee status in PaySuite. It also contains information about deleting an employee you have already created a payslip for.

Let me know if there's anything else you need help with.
