I need to delete a transaction in Accounting, but I cannot because it has a "cleared" status.

Transactions that are imported through a live bank feed or through importing a bank statement, show as cleared in the bank, once they are created. Sometimes, you may need to delete a transaction that has been marked as cleared but has not been reconciled. 

For Accounting US and Canada: 

1. Click on the Banking tab. 
2. Select the appropriate bank account. 
3. Scroll down to Activity. 
4. Check the box to the left of the date for the transaction.
5. Hover over More. 
6. Click on Remove Cleared Status. 
   NOTE: Once you have removed the cleared status, you can edit or delete the transaction. Check the box to the left of the date of the particular transaction again.
7. Click on the Delete icon.
