QBSS seems to be fine. Does what i need for my business.

QBSE doesn't seem to be a great solution for someone that rents a single property as none of the categories have anything to do with rentals, this is despite choosing landlord when setting up. And as mentioned above it doesn't seem to have a way to record and split things like my mortgage (between repayments and interest) and my solar fit tariff payments (which is tax free income). 

Also because I have a QBSS account, i have to login to QBO for that and then log out and into QBSE for the QBSE account. I can't switch between them. This is even more of an issue with the app making it more work. It would actually be easier to use QB for one solution and another software for the rental.
