Just as with your personal credit score, there are several competing organizations that issue credit scores for businesses of every size. Dun & Bradstreet dominates the field with its Paydex score, but there are also Experian's Intelliscore Plus and FICO's LiquidCredit Small Business Scoring Service (SBSS). Each service will assign your business a score between 0 and 100, with scores over 80 considered very good, and scores below 50 considered very bad.
