If you find an error in a transaction after you post, you can enter an opposing (reversing) entry to correct it.

With this type of journal entry, you can correct an error by reversing it. For instance, if transactions were entered to credit an asset account and debit an expense account, but should have been entered the other way around, you can enter an opposing transaction that debits your asset account and credits your expense account.

To reverse the original entry, you can use the posting audit report to see which entry is incorrect and then create a new journal entry in which the debit and credit entries are reversed.

To create a correcting entry, select Transaction Tasks > Enter / Edit Transactions from the left navigation pane. Enter the appropriate information in the designated fields and click Save.
