What type of Biz Credit Card do you have?
quellhorst: American Express Plum Card. http://www.plumcard.com/ 
With early pay I get 2% cash back. If you need to push payments off you can pay 10% by the due date and pay the balance 2 months later without interest charges.I try to use this card for every expense I can, it can really help you manage your cash flow.
