If you wish to establish corporate credit then DO NOT BEGIN with commercial credit (Amex, MC, Visa). This would be a MISTAKE and is akin to running before one can even walk.:P
If folks are asked to PERSONally guarantee CORPORATE credit it's because the corporation they control does not have an established presence or sufficient repayment history.
