I'm here to ensure you can delete your employee's pay record. This way, you'll be able to manage his/her status in your QuickBooks account.
You can delete an employee in his/her profile since you haven't used it or create his/her payslip yet. If you're using our QuickBooks Online Standard Payroll, kindly follow these steps:
Go to Employees menu.
Select the employee name to go to the Employee's profile page.
Click the Actions drop-down arrow.
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.
In addition, you can set up your QuickBooks account for time tracking. This will help you in tracking and billing your customers for the number of hours consumed in a project or activity. For the detailed steps, you can refer to this article: How to turn on and set up time tracking.
Please let me know if you have other concerns. I'm just around to help.
