Dear Sir,

    The check received today brings your account up-to-date. We do appreciate the effort you have made to pay the past-due balance and want to assure you that your credit is now open for the full amount of $15,000.

    If, in the course of our writing to you, we have sometimes seemed severe or demanding, I hope you will understand that we, too, are under pressure to keep collections on a current basis, if we are to keep credit costs down and to maintain our low price schedule.

    Rest assured that we consider you a favoured customer with whom we hope to continue a long and happy business relationship.

    Very sincerely,

    敬启者：

    今天收到的支票使贵方的帐目重新更新了。我们对贵方在支付过期未付余额方面做出的努力表示感激，同时想向您确定贵方公开信贷的总额为$15000元。

    如果在写给贵方的信函中，我们有时有任何言辞激烈或损害双方关系的话，我们希望贵方能给予理解。我们也是在现行的基础上承受着收款的压力。因为我们需要降低信贷成本，保持价格较低的日程表。

    另外我们还想向您表示，我们认为您是一位受欢迎的客户，我们希望和您继续保持长期愉快的贸易关系。

    敬上
