Not to derail the thread but I've incorporated my biz in the middle of '09 and have still not been able to get approved for any credit. Personal credit is spotless and I own multiple credit cards with limits of 10k in my name, but when I apply for my business I am always rejected with "No Credit History." even though I put myself down as a guarantor in the applications. Got a credit report and everything is spotless with an 800 credit score from the 3 agencies. No credit history on my business = no credit given, meaning it's a cycle of bullshit. Suggestions welcome.
definitely get a number with D&B,
most businesses have a duns number but you have to pay them $300 to get a profile with them. Or else you have no file.
Also speak to your business banker they may be able to give you a secured credit line. That's secured by cash balance. This will give you the corporate credit you need.
