We have received your letter of March 2 with thanks.

As requested， we are enclosing a fresh invoice^{2 for our services offered on August 25， 1994， previously3 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，

大家已收到你们3月2日的来信，谢谢。

遵照你们的需要，大家随函附上一份新的发票，即有关大家于1994年8月25日提供的服务，此前大家曾开出第829号发票，可能你们没收到。

因为该款逾期已久，大家将万分感谢你们立即处置付款事宜
