# App Add-ons

### How to add an Advanced app  or Business app add-on

Advanced app and Business app add-ons are available if you are on the Bravo Solo plan. Each add-on is applied to only one app.

To upgrade an app to an Advanced app or Business app , click the **Upgrade app** button at the top of the screen within the app project. This will result in a confirmation pop-up. If you confirm, the app subscription will be added to your billing cycle prorated.

The add-on billing cycle will follow your Bravo Solo plan billing cycle, meaning if you have a yearly Bravo Solo billing cycle and then adds a Advanced app add-on, the Advanced app will also be a yearly billing.

## 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.bravostudio.app/good-to-know/billing/app-add-ons.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.
