1. 文體介紹
買方收到貨物的時候也就是付款的時候，對外貿一種付款的方式很多，用得比較多的基本上有三種，即匯款、託收和信用證。
付款信是指買方在收到所訂貨物後，將收貨情況、付款方式及金額及時通知賣方。有時候買方因某種原因無法及時付款，也可以寫信給賣方要求延期付款，而賣方則根據具體情況同意或拒絕。

Subject: Asking for Deferred Payment
Dear Sirs,
Your Invoice No.1223 for US $ 80,000 worth of goods supplied on 20th July is due for payment at the end of this month. Most unfortunately, a fire broke out in our warehouse last week and destroyed a certain part of valuable consignment. Our claim is now with the insurance company, but it is unlikely to be met for another three or four weeks and until then we are faced with a difficult financial situation. I am therefore writing for permission to defer payment of your invoice until the end of September.
As you know, my accounts with you have always been settled promptly and it is with the utmost regret that I am now forced to make this request. I hope, however, that you will find it possible to grant it. In doing so you would render me a service I should never forget.
Yours faithfully,
xxxx
主題：要求延期付款
親愛的`先生：
貴方7月20日所供第1223 號發票項下貨物之款項80000 美元定於本月底結付。非常不幸，上星期我方倉庫發生火災，毀壞了一部分貴重貨物。我們現在正向保險公司提出索賠，但在三四個星期之內，不可能會給予賠償。在此之前，我方財務形勢嚴峻，故此我們寫信請求貴方同意我們推遲到9月底付款。
貴方知道我們一向能迅速與貴方結帳。這次我們被迫向貴方提出這個要求，實在抱歉。我們希望貴方能同意這個要求。若是如此，我們將永遠記住貴方給予的幫助。
你真誠的xxx
