I don't get it when people say they can't pay their credit card bills for any creditor via external sources. I set up First Tech, UNFCU, BofA to be paid through my fidelity bill paying portion of my brokerage Fidelity account. I pay every one of my bills via this. Now perhaps the transfer doesn't go through ACH; I don't know. All I know is when the payment shows up from the Fidelity account, the next day it shows up on the credit card bank's account. What am I missing? (I haven't paid a bill any other way for at least 15 years).
