# How does your billing cycle work?

Our billing cycle for self-service plans starts on the day of purchase. The next billing cycle's payments are automatically authorized.

With other plans, unless otherwise specified, the billing cycle starts on the first day of the month. An invoice will be sent to you, and it must be paid within seven days.

While you cannot change the date of your billing cycle renewal, you can always top-up or upgrade your plan at any time.

## 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://developers.oxylabs.io/help-center/billing-and-payments/how-does-your-billing-cycle-work.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.
