Bank Charges on Receipts

Hi,

A customer deposited $20,000/-  in our corporate bank account. The local bank charged us with 15/- as bank charges. My invoice amount shows 20K but when i apply this invoive to receipt 20k less 15, it shows me a balance due. This affects my aging report.

How can i handle this from receivables.

I tried it by making an adjustment and it works fine except that it credits the receivables account. I want to credit the bank account here. Is this possible?

Anyone suggests a better idea?

Thanks.
