B: As you know, we prefer the L/C 20 days in advance which expires 15 days after receiving the paking list.
A: I suppose you have known our financial standing and credit well now after our long-term cooperation.We know an irrevocable L/C can ensure that the seller gets payment duly.But, on the other hand, it would increase the buying cost.Therefore, could you consider giving us D/P this time?
B: I am sorry.But our rules only allow us to accept other terms of payment by L/C, although the buyer has had two or three transactions with us before.
A: But why not if you have known the buyer's credit after several deals?
B: We hope you can understand.We have got some serious lessons from the credulity.One of them was through D/P documentary collection.When the shipment worth US $50000 was effected, the buyer refused to make the payment.But we can do nothing with it.And that buyer had had one or two deals before this one.
A: I see.But the flexible terms of payment will definitely bring you more orders as well as facilitate the buyers' purchasing.
B: Sure.We don't mean we won't accept other terms of payment forever.As a matter of fact, we will do so when we have known well about the buyer's credit after a real long-term cooperation.
