Ink Plus and Ink Cash
I do have both cards under the same business name.
I didn't apply for both together - Ink Plus is a year old, Ink Cash is a month old.
Tip: if you already have the Ink Plus and want to apply for the Ink Cash for the same business, have a reason (I told the CSR on the reconsideration call that I wanted to have business restaurant expenses in a bonus category), and be willing to move credit from the Ink Plus to the Ink Cash.
