写这样的催款函，要求文字简洁，意思清晰；同时，语气要真诚、体贴、合理。不要轻易怀疑对方故意拖欠，以免伤害对方的感情，不利于达到索赔的目的，或妨碍未来的业务。对于一些反复催促不付款、故意逃避付款的客户，语气应强硬，措辞坚决。简而言之，我们应该掌握一个原则：不仅要达到索赔的目的，而且要与客户保持友好的关系。

（1）subject: Demanding Overdue Payment
Dear Sirs,
Account No.8756
As you are usually very prompt in settling your accounts, we wonder whether there is any special reason why we have not received payment of the above account, already a month overdue.
We think you may not have received the statement of account we sent you on 30th August showing the balance of US$ 80,000 you owe. We send you a copy and hope it may have your early attention.
Yours faithfully,

亲爱的先生：
第8756号账单
我们没有看到贵方回复我们9月8日来信要求结算。我们再次写信提醒您，欠款为8万美元。毫无疑问，一定有特殊原因推迟付款。我们期待贵方解释原因并发送汇款。

（3）Subject: Insisting on Payment
Dear Sirs,
Account No.8756
It is very difficult to understand why we have not heard from you in reply to our two E-mail of 8th and 18th September for payment of the sum US$ 80,000 you are still owing. We had hoped that you would at least explain why the account continues to remain unpaid.
I am sure you will agree that we have shown every consideration and now you fail to reply to our earlier requests for payment, I am afraid you leave us no choice but to take other steps to recover the amount due.
We are most reluctant to do anything from which your credit and reputation might suffer and even now we prepare to give you a further opportunity to put the matter right.We therefore propose to give you 15 days to clear your account,
Yours faithfully,
xxx
催款函主题：三次索取欠款
亲爱的先生：
第8756号账单
9月8日和9月18日，我们两次到信中要求支付8万美元的欠款，但我们还没有收到贵方的任何答复。我们觉得很难理解这一点。我们希望贵方至少能解释为什么到目前为止还没有支付账款。
我想你也知道我们很关心你，但你没有回复我们之前的两封询问信。恐怕你别无选择，只能采取其他步骤来收回欠款。
我们不愿意做任何损害你声誉的事情。即使是现在，我们也准备再给你一次恢复这件事的机会。因此，我们将给您15天的时间结算账目。
