When creating a bill there is a list called category. How can I edit this list? When I try product/Services and select More. Click on category. There is no list to edit.

Thanks for dropping by the Community to post your concerns, @Delboy. Let me help you modify the details you need in QuickBooks Online.

If you want to modify the list in the Category section while creating a bill, you're unable to do it from the Product and Services page. However, you can do it from the Chart of Accounts. It enables you to view the account list that will appear on the category list.

I'll show you the steps on how: 

1. Go to the Accounting menu and choose Chart of Accounts.
2. From there, select the account, then click the drop-down icon to Edit.
3. Click Save and Close once done.
