# Billing

The account's invoices, payments, and the service plans its devices are on.

Billing covers what the account owes and how it pays: invoices raised against it, the providers it can pay through, recurring payments, and the history of both. It also covers the service plans that decide what each device is allowed to do.

An integration usually needs [Transaction](/docs/navixy-api/user-api/resources/billing/transaction.md) to read history and [Tariff (plan)](/docs/navixy-api/user-api/resources/billing/tariff.md) to find out what a device's plan permits. Raising and settling invoices is the rest.

## 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://navixy.com/docs/navixy-api/user-api/resources/billing.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.
