Am sitting here doing my accounts in the UK. To me, Cashback is almost like an in-store ATM. It means "I have paid for something using my debit card, and the store has ask me if I would like any cash to go with the purchase". I'd then pay the extra amount, and the cashier would hand me some notes.
In other words, it's an expense. Similar to an ATM, in fact so much so that I created a category of 'Cash Machine' to which both ATM and cashback transactions go. I have taken from my balance and convert it to cash.
Now, Quicken too has something called Cashback as a category, but it's listed as an income. I'm curious - what's the intent of that category? What in the US comes under the term cashback? Refunds? Discounts perhaps?
Cheers, Ian
