    We received payments of $275 on the 2nd July, and $525 on the 9th July respectively. This leaves a debit balance of $320. We would like to remind you that in your letter of the 22nd June you promised to repay before the end of June.

    要求支付逾期款
 
    我们已收到你们3月2日的来信，谢谢。

    遵照你们的要求，我们随函附上一份新的发票，即有关我们于1994年8月25日提供的服务，此前我们曾开出第829号发票，或许你们没收到。

    由于该款逾期已久，我们将万分感谢你们立即处理付款事宜。

    A Letter to Demand the Payment of Overdue Account

    Dear Sirs,

    We have received your letter of March 2 with thanks.

    As requested, we are enclosing a fresh invoice for our services offered on August 25, 1994, previously billed under our invoice No.829, which you could not find.

    Since the account is long overdue, we would very much appreciate your prompt processing of payment on your side.

    Yours faithfully,
