I have recently founded an LLC with the usual banking facilities. In addition to the corporate miles programme, I was wonderng about a couple of hacks e.g. 1) LLCs can accept credit cards for services/goods. It can also make refunds via other transfer mechanisms. 2) Sometimes LLCs need loans from shareholders, which could perhaps be via a credit card payment. They then repay these loans, plus interest and loan processing costs. I cannot be the first to consider these topics, surely?
