No one stated you have to redo anything. You asked this question, "Is there any other way of bookkeeping?" and that is what I provided. You can stop using your old method or not; you can redo your old work or not. No one is telling you what you have to do. We are telling you how to use the tools provided in QB. "need to change" would be your decision, of course.
You won't use invoices; you told us these represent payments that you are considering income for the date you got paid. What I described, is that you are not going to have Sales Info in QB using journal entries, because you are doing Banking, not Sales. You are using about 5% of the program tools.
