We had an overcharge yesterday because it was keyed in wrong. Could there be a second prompt after you click process payment? Maybe prompting are you sure you want to process with cost showing. I realize its an extra step but an extra click would take no time at all. Also when you go to refund an charge in the admin. portal the drop down menu gives you options of why we are refunding and I feel it would help to have one that says overcharge or operator error. Thank You
