How do you record a wire transfer from a customer in AR? In AP there is the selection drop down for Wire Transfer, but not in AR. I read if we use ACH/Credit Card, it doesn't post to BR. So do we use Cash and if so, how/where do we enter the long 15 digits…

A prepayment was incorrectly made, and due to some confusion was also entered in negatively so it shows up as a positive number in the aged invoice report. Is there a way to delete a PP or reverse it? This is on the A/R side. Thank you.
