I set up my citibank costco card and had the payment account verified with the deposits but after all the setup was done the only options for payment is "checkpay" , "pay" and "enter" there is no Quickpay.
Checkpay is just that - mailing a check. Pay makes an entry in the payment account that has to be sent and "enter" just makes an entry in the payment account. All this just seems like another version of the transaction reminders.
