Sincerely，

主题：付款可能延期
尊敬的张女士：
我们对你们的产品质量非常满意，也很高兴能和你们公司建立起很好的合作关系。我发现上一次订单我们没有按时付费，现在已经逾期两周了。我们非常感谢你们的理解，不知你们能否将这笔款的付款日期延至1月1日。届时，我们定会全额付清这笔费用。不知你们是否能够为我们延期？
诚挚的杰克·乔根森

Subject：Unforeseen circumstances
Dear Ms. Giles，
I regret having to ask you for an extension of the deadline for payment on our order of March 25th. However, unforeseen circumstances in the form of a tornado destroying our headquarters have made it nearly impossible for us to make payment on time.Due to this unexpected act of God, we have lost access to all of our computer systems, resulting in a delay of at least two weeks before everything gets back online.In light of this situation, we respectfully request an extension of 30 days on our account.
Sincerely, Gordy Portero
主题：无法预知的情况
尊敬的贾尔斯女士：
很抱歉，我不得不向您请求延长我们3月25日的订单的付款期限。不可预见的情况发生了，一场龙卷风袭击了我们的总部，因此我们应该无法按时付款了。由于这一意外的天灾，我们无法使用计算机系统，因此要恢复正常的工作至少需要两周。鉴于这种情况，我们诚挚地请求将我们的付款期限延长30天。
诚挚的戈迪·波特罗
