Dialogue : How to make payment? Buyer: Apparently, it is practical to make our payment for the complete set by installment, because the order includes not only your equipment, but also your service of installation, trial run and staff training. Seller: Sure．What is your opinion on the installment payment? Buyer: We think it is fair that we make a down payment on the delivery of the equipment．And then we will pay off the rest in three payments according to the progress of the project. Seller: We may agree with your proposal．So, the down payment actually is worth the equipment that you purchase. Buyer: We would like to pay it by L/C. Seller: Sure．But you must open the L/C at sight one month before the shipment is made. Buyer: No problem.
