​How much cash do you keep in your business bank accounts?

I run a people-services company, with a few employees (<7 total). It’s an LLC that I solely own (elected S-Corp). By far, my biggest expense is payroll, we invoice high, and I pay our employees high.

Right now I have ~$200k in the company bank account, obviously not optimal. I want to keep ~$45k in the bank at all times just to make sure at least our largest expense clears the bank.

What do I do with the rest? Should I just pay it out to me, and then in case of an emergency I just loan it back to the company? Since I’m an LLC S-Corp I’ve already paid taxes on this money, so I should probably just take it as distributions? Thoughts?
