Actually you should notify me before if the price can,t be amended as we are not aware of this matter. This will complicate our cost structure for the actual shipment to Thai FDA from different COGS and different selling price.
The reason that we have to swap the invoice is because we faced delay delivery by 1 shipment in September from what was confirmed earlier. In order to minimize the penalty charge which we have to shoulder ourselves from this delay, we then have to deliver first the product for second contract.
In case you really have difficulty to adjust the price, then I would need you extra effort to fast track the delivery to TH soonest.
