So the deposit was posted correctly to each customer but entered onto deposit slip incorrectly. And the bank will correct it but not in time for the month you are doing bank rec in.

You can post a general journal entry to put difference into a suspense account (or bank interest charge expense acct) with comment of something like To Adjust for Jun30/14 Deposit adding error. Then when the bank corrects it you can do same journal entry but in reverse for date the bank correction is made on.

If the bank is not going to correct it then I would just expense it to bank charges.

That's what I did before posting the concern.  Thank you.
