Ten years ago Experian, Equifax and D&B were the major players in business credit reports and scores. Experian's Intelliscore, Equifax's Small Business Financial Exchange and D&B's Paydex score. While those business credit agencies are still around and producing their reports and scores, the "cash lending" industry has mostly moved to FICO SBSS (Small Business Scoring Service). The Paydex score is still widely used by Vendors who are providing business to business lines of credit on Net 30 terms for their products or services, but most cash lenders such as banks, SBA loans and many others have moved to FICO SBSS.
Generally if your FICO SBSS is below a 160 your business will not be considered bankable. The range of FICO SBSS is 0 to 300 with a score of 160 and being considered the minimum to not get declined.
The issue with FICO SBSS is that every lender has the ability to design and weight their own. What this means is that for their FICO SBSS scoring method lenders have a list of items they can select from and assign weight to such as the personal credit of up to five owners that could make up as much as 35% of the FICO SBSS score. Other items that can be part of the score are; Experian/Equifax/D&B business credit scores, the time in business, bank rating, web presence, industry, gross annual revenue, net income, gross margins, debt to income, and more. This means that your business FICO SBSS score might be different at Wells Fargo than it is at BofA. This is why there is no place to simply purchase your FICO SBSS.
