What so you use your “cash account” for/ what do you use it for?!

[William Bowers]

how should you use your cash account? What do you use your cash account for?

I have 6 units 5 long term and 1 STR. Im starting to see a decent amount of cash flow (average is a little less than 10k) I pay some utilities and some tenants pay there own. Obviously have mortgages, taxes etc. I am in the process of getting a business credit card. Should I start paying for everything on this credit card then pay it off monthly with the cash account? Does anyone recommend a specific use for a company card?
