I try to make sure I have separate receipts for home and business, but sometimes that doesn’t happen. In those cases, I will mark out personal items on the business receipt and re-calculate. As far as bulk items I buy like flour, eggs, or butter, if I “borrow” a couple of eggs or a cup of sugar from the business I don’t get too worried about it.
