催款函是卖放在规定期限内未收到货款，提醒或催促买方付款的函件。
写此类催款函要求文字简练、意思清楚;同时要求语气诚恳、体贴，彬彬有理。不可轻易怀疑对方故意拖欠不付，以免伤害对方感情，不利于达到索款的目的，或妨碍以后的业务。对于某些屡催不付，故意逃款的客户，语气则要强硬，措辞坚决。总之索款要把握一个原则：既要达到索款目的，又要与客户保持友好关系。

催款函主题：三度索取欠款
亲爱的先生：
第8756号账单
我们于9月8日及9月18日两次去函要求结付80，000美元欠款，单至今未收到贵方任何答复，对此我们感到难于理解。我们希望贵方至少得解释为什么账款至今未付。
我想你们也知道我们对贵方多方关照，但你们对我们先前的两次询函不作答复。你们这样做恐怕已经使我们别无选择，只能采取其他步骤来收回欠款。
我们极不愿意做任何损害你们信誉的任何事情。即使现在我们还准备再给你们一次机会来挽回此事。因此，我们再给你们15天时间来结清账目。
