Small business owners can report delinquent debts to the three major credit bureaus - Experian, Equifax and TransUnion - however the small business must first become a customer of the bureaus, a subscriber to its credit reporting services. This may or may not be practical or represent something that the small business really needs. Alternatively, delinquent debts can be reported to Dun & Bradstreet and Experian, who maintain business credit reports.
