Thanks for your reply.

To answer "what are you using QBO for?" ... as yet, I'm really not sure. I'm experimenting with it to see what it can do for me as I leave full time PAYE employment and move over to being an IT sole-trader (not VAT registered) who also happens to have a rental property. My hope was that it would help me stay organised enough to make my self assessment submission easier. So: my idea was to use it for both income streams and the relevant expenses. Having played around for a few days, I am coming to the conclusion that it actually makes life harder rather than easier. But that could just be my initial inexperience and unfamiliarity with its jargon.

In reply to "raise invoices": I'm trying to get the data for the 2021/2022 tax year into the system so I don't think I want to raise invoices for payments I have already received. Hence I am going through the transaction classification process and the big thing I am looking for help on is
* how to choose the right classifications for the four parts of the payments (am I doing it right?).
* how to classify only half of the payment (because the property is shared with my wife)

In reply to "set up the chart of accounts": Can you explain in simple terms what this is (because I dont "get" it).
