We are going to modify the issuance of Payment Receipt function in order to deal with the receipt of foreign currency for the payment of a Hong Kong dollar invoice. The new Payment Receipt will display the full amount receipt in “foreign currency” and the invoice balance outstanding in Hong Kong currency. The existing Payment Receipt shows the gain or loss in foreign exchange as the outstanding amount and that is not correct. If you do encounter this problem please call us to update the system to its latest version. Sorry for any inconvenience caused.
