Spreadsheets give me hives.
Currently, I use a calculator to work out income and expenditure balances, but I'm sure there must be a formula for this - a one time set-and-forget thing - which would make it easier.
I have four columns:
Item - e.g. Amazon Payment, Fussy Librarian promo cost
Income
Expenditure
Balance.
Actually, there's a fifth, where I record a dollar price (I work in pounds sterling) if I've had to pay out in that currency (that's mainly promos and covers - my designer is in Australia)
I use it only to check on price increases (more rarely, decreases!) since my last promo/cover and would be prepared to forgo it if it messed with any formula.
I've tried Googling for an answer, but either can't find one to match my situation - or can't understand the answer when I do. (Did I mention that I'm a techno-numpty as well as being allergic to spreadsheets?)

So, how do you record your accounts? Any help would be much appreciated. Thank you.
