Reverse the entry made in the bank module and process a Deposit Batch.

Thank you for your reply.  Is it possible not to touch the banks and just do it directly in the AR module?

Why??  It should not have been done in the Bank in the first place.

True.

I am coming from Sage 100 and in Sage 100, there is what you call a zero cash receipt.  Instead of using the account code for the bank, you use a gl account.  Is there such thing in Sage 300? Thanks

Misc Receipts

Misc Rec won't do what you want.  Only way to complete an invoice is to do it in AR.  Receipt in AR is going to DR Bank and CR AR.  Misc Rec is going to Dr Bank and Cr GL account and not touch an invoice. 

You may have to do a GL entry to Dr Cash and Cr "some account" then do a credit note in AR that will Dr "some account" and Cr AR.  This will clear the invoice.
