Best way to build business credit is to find businesses that report to credit bureaus. When you do business with another business, ask them what bureau they report their accounts to. My business is looking at reporting to Credit Safe and Experian once we have enough accounts to report.

The government no longer uses Duns and Bradstreet and Paydex to track credit. Now they just use your EIN number on Experian and SPFE, according to my insurance broker.

Best way to look good is to appear on these websites:

-visapedia
-nav.com

If you want to talk about it more, book an appointment with me! My firm does business operations, but at lot of those operations require obtaining capital first.
