Thanks for posting in the Community, kbbk.
Let me guide you on how to add a new pay category for your employee's commission in QuickBooks.
- Go to Employees tab.
- On Payroll Settings, select Pay Category.
- Select Add.
- Name the pay category, then select Save.
- Complete any relevant fields, then select Save.
Once done, you can manually add the commission on the pay run by selecting Actions and then Add earnings.
For more detailed information, you can check on this article: Create and manage Pay Categories.
