But I can definitely tell you that I pay them every week or two and pay more than I owe and show a credit balance with no problem. My online bill pay takes maybe a couple of days to post.
I've occasionally overpaid the same way. Signed up at Chase's web site and linked my bank account to pay with. Every month I log in to Chase's web site and tell them how much to pay which they deduct from my linked bank account. I haven't done it on a regular basis and not for large amounts but it has worked for me.
