When you do a Sales Invoice or a Cash Sale (Receive Money) two things occur - the income in the foreground (which you can see on the screen) and the adjustment to inventory/cost of sales in the background. In fact, the exact same entries in your journals will occur, but done automatically.
The other limitation with Journals is that you can’t use the Cash Accounts tab.
Can I suggest that you read this guide. Then set up a test business (or use existing), create some cash accounts and test inventory and then create a Cash Sale (Receive Money) using an actual sale. Then come back with any specific issues.
