1. 文體介紹
催收信是賣放在規定期限內未收到貨款，提醒或催促買方付款的函件。
寫此類信要求文字簡練、意思清楚；同時要求語氣誠懇、體貼，彬彬有理。不可輕易懷疑對方故意拖欠不付，以免傷害對方感情，不利于達到索款的目的，或妨礙以后的業務。對于某些屢催不付，故意逃款的客戶，語氣則要強硬，措辭堅決。
總之索款要把握一個原則：既要達到索款目的，又要與客戶保持友好關系。
2. 實用范例
（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,
xxx
主題：索取逾期賬款
親愛的先生：
第8756號賬單
鑒于貴方總是及時結清項目，而此次逾期一個月仍未收到貴方上述賬目的欠款，我們想知道是否有何特殊原因。
我們猜想貴方可能未及時收到我們8月30日發出的80，000美元欠款的賬單。現寄出一份，并希望貴方及早處理。
你真誠的xxx
（2）Subject: Urging Payment
Dear Sirs,
Account No.8756
Not having received any reply to our E-mail of September 8 requesting settlement of the above account, we are writing again to remind you that the amount still owing is US$ 80,000. No doubt there is some special reason for delay in payment and we should welcome an explanation and also your remittance,
Yours faithfully,
xxx
主題：再次索取欠款
親愛的先生：
第8756號賬單
未見貴方對我們9月8日來信要求結算一事之回復。我們再次來函提醒貴方，欠款為80，000美元。毫無疑問，一定有特殊原因使貴方延誤付款，我們期待貴方說明原因并寄上匯款。
你真誠的xxx
（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
主題：三度索取欠款
親愛的先生：
第8756號賬單
我們于9月8日及9月18日兩次去函要求結付80，000美元欠款，單至今未收到貴方任何答復，對此我們感到難于理解。我們希望貴方至少得解釋為什么賬款至今未付。
我想你們也知道我們對貴方多方關照，但你們對我們先前的兩次詢函不作答復。你們這樣做恐怕已經使我們別無選擇，只能采取其他步驟來收回欠款。
我們極不愿意做任何損害你們信譽的任何事情。即使現在我們還準備再給你們一次機會來挽回此事。因此，我們再給你們15天時間來結清賬目。
