Hi Mazaya.
Being able to track your expenses that you pay for using your personal accounts is crucial to make sure you can receive those funds back once your company accounts are made. I'd be happy to help you with why your journal entries are not showing in the expenses or supplier tabs.
When you post a journal entry it doesn't show in either the expense or suppliers tab. This is due to the journal entry posting only to the accounts that are selected. If you wish to have it show under the expense or suppliers tab I recommend reaching out to your accountant to see if they have any other ways to post it that'll allow it to show in those sections also. If you don't have an accountant no worries, we can help. In your QuickBooks Online account you can go to My Accountant>Find a pro to help to find one in your area.
If you have any questions let us know and we'd be happy to help.
