I only use cash. I carry 200. - 300. in my wallet so I don't have to use ATM's. But it lasts me a very long time as I only buy what I need or desperately want to reward myself for working hard. Plus I get a headache when I go shopping, so you won't catch me shopping unless it's Christmas time. And you can see from my photos, I don't spend my money on clothes.
Exact opposite from my personal. I use my business credit card for everything as it makes my bookkeeper very happy. I keep a minimum amount in my business checking to pay business expenses, and every time the balance exceeds that amount, my financial advisor transfers it to a Simple IRA where it can earn a higher interest. I keep it in a Simple IRA because I'm looking at buying a building and need to be able to access that money quickly and without fees when that situation presents itself.
