Key Bank credit cards are processed/administered by some other financial companies.
I have a personal credit card and Elan Financial administers it and reports to all my CRB.
the chase INk and Ink bold cards report only to business credit but require a PG, they have rewards and transfer to partners at 1:1 too. I love dealing with them, never had a bad experience. I know young-guy is having a rough time with them but that is a special case.
the northern tool card is issued by hsbc and done without a pg, so is bestbuy for business
