I look at business credit cards like this. They are a great way to start the process of obtaining credit for your business and they are good for small purchases.

I know a lot of people use them as the sole means of financing their business. First let me tell you thats a really bad idea. There are many financial vehicles available these days to help you to obtain credit for your business. For instance:

• SBA Loans - govt backed loans. The most common are the SBA 7A & 504. They also have the 8A which is for minorities
• Equipment Leasing - these companies finance the purchase of equipment only. They have a variety of programs for businesses at all levels. So whether you are established or a startup or good or bad credit, they probably have a lease for you.
• Factoring & Purchase Order financing - I need to do some more research to find reputable companies, but basically these types of companies use your accts rcv or purchase orders to provide a form of secured financing.

A credit card should be used to pay merhants & vendors. Not used as the single form of financing for your business.
