Manage suppliers and expenses

I'm glad to know that you're using QuickBooks to track your personal transactions, MrMiyagi.

The P&L in QuickBooks Online will show all your expenses whether they are personal or claimable. However, you can re-assign your non-claimable transactions to a different category, then deselect it from the report.

The screenshot below shows how I deselected the Personal Expenses account I created.

On other hand, to re-assign your transactions, you'll want to change the Expense account assigned to your items. Then, select the option to affect your historical transactions, so you won't need to go through each of them.

If you directly used expense accounts on your transactions, you need to go though each of them. 

You can always go back to this thread if you still need help with your report.
