I would like to be able to login once I have approval to pay the invoice (this is always before the actual due date) and schedule the payment for the due date (a later date). Not being able to do so, I have to either pay too early or remember to login and pay on the due date or very shortly before. If I fail to for any reason then there are late charges added on. Give me the option to choose the payment date and this would be the perfect portal for bill pay in my opinion.
