I am interested in getting into the business credit card game in order to maximize my points for my CSP/CSR, however I have seen that I can use business cards to maximize points which is great and something that I am looking into, however can anyone help me understand the difference between the Ink Unlimited/ Ink Cash when it comes to points maximization?

From what I have heard here is what I was told:

Ink Cash - Cash only

Unlimited - Even though it says cash only on the site, you can transfer it to your CSR/CSP

From what I just seen briefly on the Chase site:

Both: They both can be used in the CUR but doesn't say anything about transferring points to the CSP/CSR

Can anyone give me insight in if both cards are eligible to maximize my points? I do not care about the Cash back after getting the bonus and will not care about it afterwards and will close it/leave it open and forget about it.
