is it possible to have certain types of income offset against the expense for a given category? I'm thinking of things like medical expense, where one typically might claim back a certain amount from the medical aid. So you might spend R1000 at the doctor, but get back R800 from medical aid, so that the actual expense is only R200.
At the moment I just categorise these non-salary incomes into the correct category, but it might be useful to see the actual amount that you spent. It does get complicated though if the expense and income happens in different months though.
Anyway - a suggestion, let me know what you think.
