Hello @MagicPinball,
Thank you for reaching out to the Community. Bill Manager is not designed to use credit cards as payment accounts. It will let you set up a checking account as a payment account.
If you're asking about setting up Capital One and Discover as Online Billers that you want to send payments to using QuickPay, then the answer is:
Capital One cannot be set up as an Online Biller and does not support QuickPay.
Discover can be set up as an online biller and should be able to receive payments using QuickPay.
Thank you.
Thank you for your response,
If its still giving you trouble, let me know and we can look into it further.
