# 退款

退款用於記錄某筆原支出退回的金額，並讓實際支出、帳戶餘額和相關統計一起更新。

## 記錄退款

1. 在首頁或搜尋結果中開啟原支出帳單。
2. 在帳單詳細資料選擇 **退款**。
3. 輸入退款金額，選擇入帳帳戶和日期。
4. 依需要填寫幣別、標籤、地點、圖片或備註。
5. 點一下數字鍵盤右下角按鈕儲存。

退款會與原支出關聯。部分退款後，可以繼續從原支出記錄剩餘退款；退款記錄也會顯示在原支出詳細資料中。

## 編輯與刪除

開啟退款帳單詳細資料，可以編輯退款金額、入帳帳戶、日期和其他內容，也可以刪除退款記錄。修改或刪除後，原支出的實際支出和帳戶餘額會重新計算。

{% hint style="warning" %}
不要用一般收入代替退款，否則退款不會與原支出關聯，原支出的實際金額也不會正確更新。
{% endhint %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.daak2.com/zh-tw/tui-kuan-yu-bao-xiao/refund.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
