You're actually talking about a Corporate Guarantee... If You have an account(Company A) already with a Supplier/Vendor/ Whomever, and you want to use that credit status to open up another account(Company B), or in essence "Guarantee" the worthiness of the new account(Company B), as long as Company A's credit is Strong enough to carry A &B You Can.. But again You'll most likely have to sign an Corporate Guarantee... And make sure you read all the legal verbiage in the guarantee, some are tricky while others or straight forward...
