大部分公司對于合理的索賠和投訴都會給予肯定的答復。通常公司是歡迎顧客的投訴的，這樣它們就可以知道產品或是服務都有哪些不足，從而改善和提高。答復投訴和索賠信應遵循下面幾個原則：
1. Reveal at the beginning that the claim is being granted.
2. Explain the
circumstances.
3. Close courteously and positively.
當賣方是錯誤發生的責任方時，賣方在答復中需要解釋清楚錯誤情形。如果不解釋清楚，買方就會認為當前的交易不是一樁好買賣，可能會轉而尋找其他賣家。如果解釋過于龐雜，買方可能沒有興趣看或是認為賣方業務運作過于復雜。因此在解釋錯誤原因時說清楚主要的幾點即可。
承認錯誤后還應承諾改正錯誤和改善以后的工作。這是重新贏得客戶信任的一個重要步驟。注意：可別說以后再也不會犯錯，因為錯誤是不可避免的。
最后，還要表示繼續合作的希望。畢竟，要贏得客戶并不容易，所以要維護好客戶以免流失。
下面是一封對索賠和投訴的肯定回復。由于是賣方發錯貨，我們來看看賣方是怎么答復的：
