What type of Biz Credit Card do you have?
pxlpshr: AMEX is one of the best cards for floating monthly expenses. Customer service is top notch, and you often get an extra year warranty on anything you buy. If you're irresponsible, prepared to get slaughtered by high interest rates that pay for these services... That said, I would not use an AMEX to bootstrap a company. You can find a better interest rate through VISA/Mastercard.I currently use an AMEX Blue (cash back) for my personal stuff, balance is paid IN FULL every month. And we have a business checking account for the iPhone company. $5/month through Wells Fargo.While I keep a few accounts at Wells Fargo, I bank through ING Direct. Love everything about ING, and they have great leadership. One complaint: for an online bank their web interface is freaking terrible.
