A PAYDEX score is the business credit risk score that Dun & Bradstreet generates for businesses. It ranges from one to 100 and is based on your business’s payment history. If you pay invoices or other debt on time, your PAYDEX score will be higher. A higher score indicates you’re a less risky company for another business to work with, and can help you get access to small business loans, business credit cards, or other financing — generally with better terms and interest rates.
