An Apex Clearing (ACH) bank reversal takes place when a transfer of funds is cancelled. This may occur when there are insufficient funds in your bank account, there is a duplicate transaction, the transaction is denied, or when the type of account is incorrect. In the event of an ACH reversal, a $30 fee will be incurred by the user and the funds will be returned to the original account. Stash is not responsible for any ACH reversal fees incurred by the user.
