- Modifying the transaction's status in the register. For example, from reconciled (R) to cleared (C) or neither (blank), or when an unreconciled entry was changed to reconciled (R).

- There are missing or duplicate transactions in QuickBooks.
- Someone entered a transaction in QuickBooks that hasn’t cleared the bank yet.
