Some payment modules do not always perform as expected and, occasionally, this can lead to lost orders. In that case, there is nothing to be done since the order was never recorded in the database. This addon makes a duplicate record of each order, even if it fails. So, no matter what, you can always retrieve the information should the regular order process not work. This doesn't happen very often. But, if it does, you will be very happy to have this option available.
