Supaporn,
Since I had to manually go back and reconcile your account for 2 years it was a typo on my part.
Dec 2014 invoices are correct.
I have fixed the following as I missed typing in Invoice C064475. Please review against the original I sent you.
I believe this issue is now closed.
Please make sure your payment is received in office by September 18th, as since this is your first payment since re-establishing terms to your company and is already a month past due!!
