I fielded a call by a small business owner today interested in building credit. The entrepreneur wanted to expand his cleaning service and had read “something about corporate credit” but did not have an adviser to guide him through the process.

Answer: The simplest and easiest way to build business credit is to register your business on www.dnb.com and get a DUNs Number. Corporate clients often verify a company’s track record by checking trade references in Dun & Bradstreet’s database, the largest repository of business information in the world. Visit D&B’s Web site to get your DUNs number.
