Refer to below email, one issue need discuss with you side:
For payment term, we can revise that according to agreement between LVT and LVC, but as you know, PO14-00219 & 13-00367 equipments had been finished fabrication process a long time, till now we didn't get any shipment information but we already paid many advance payment to our sub-suppliers, for this problem, how to solve?
In order to avoid the similar risks, it is better that we have to place some advance payment in our quotation.
your highly understanding will be very appreciated!
