The payment amounting 9400 that you mention and the payment amounting 50,006 which paid on 25/09/2013 were the cost of sale invoice 003 for repairing the faulty machine. But CPT and MIT still can not handover this project to end-user (AOT) because they required other repair and it is in process of end-user. So, MIT has not paid for this invoice. It should be done by May 2015
