# Exchange note
Exchange notes give your customers a printed slip showing which products can be exchanged and until when. Perfect for gift purchases or situations where the buyer isn't sure about size or fit, or if its a gift.
## How does it work?
When processing an order, you can select which products you should print exchange note for. Flow Retail calculates the exchange deadline automatically based on the number of days configured in your store settings.
The printed note shows the product name, variant details, and the final date for exchange—without revealing the price. It also prints the barcode of the order reference number, so you can quickly scan that to get the original order, and to start the return/exchange process.
## How do I get started?
#### Configure the default exchange period
Set how many days customers have to exchange products in your store settings:
1. Go to **Admin → Stores** and select your store
2. Find the **Exchange note days valid** field
3. Enter your preferred number of days (e.g., 30)
4. Save your changes
#### Print an exchange note from a new or an existing order
1. On the Complete page from an order, click Exchange Note, or open an existing order and choose Exchange Note
2. Select the product that needs an exchange note
3. Click the **Print icon**
4. Hand the printed slip to your customer

## 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://docs.flowretail.com/docs/day-to-day-operations/selling/exchange-note.md?ask=&goal=
```
`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.
