2--You know Mr. Forster,this is a really larae purchase. I am afraid we can't pay off at one time. We have to pay by installment.
 
1--Do you mean you prefer a deferred payment?
 
2--Yes,Mr.Forester.
 
1--When do you start the payment then?
 
2--We'll start our payment in half a year and the total amount will be paid off within 2 years by three installments.
 
1--We can accept that but you have to pay the interest.
 
2--All right.
 
1--Shall we sign the agreement now.
 
2--Ok,let's sign it.

1--王先生，我们还没商讨付款的方式呢。
2--福斯特先生，您知道这确实是一大笔购货恐怕我们无法一次将款项付清，只能分期付款。
1--您是说希望采取延期付款方式？
2--是的，福斯特先生。
1--那么你们什么时候开始付款呢？
2--我们半年之后开始付款，所有的款在两年内分三次付清。
1--我们可以接受这一付款方式。但是你方需要付利息。
2--那好吧。
1--我们现在就签署合约好吗？
2--好的，我们签吧。
