# Time Slots

If pre-order is enabled, customers can choose a preferred time slot during checkout.

These can be configured based on venue needs.

{% hint style="warning" %}
**Do not change the settings in the in the middle of service hours.** Adjusting these values mid-service can cause allocation errors, as existing orders may no longer fit the updated intervals or capacities.
{% endhint %}

## Time Slot Days

Venues can allow customers to book a time slot **up to a specified number of days in advance**.

{% hint style="success" %}
If Time Slot Days is set to 0, it will only allow pre-orders for the current shift. This factors in the **day offset value** which allows customers to pick time slots for hours past midnight that are still within the current shift.
{% 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://docs.bossithq.com/web-app/time-slots.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.
