# Performance vs Billing Data

DT offers two different methods to analyze Offerwall event data which refers to actions performed by users e.g. clicks, installs and conversions. The first method is chronologically-based, meaning we aggregate and report on events as they occur in real-time. The second method aggregates event data and attributes it to the first touchpoint that the user had with an offer which is time of click.

* Event data aggregated in chronological order is referred to as **Billing Data** in DT’s reporting tools. It is also what DT uses for billing purposes.
* Event data aggregated to the time of user click is referred to as **Performance Data** in DT’s reporting tools.

## Example

Let’s assume we have an offer that requires a user to install an app and reach level 10. This means, what the advertiser deems as a *conversion* is the user reaching level 10. Consider the following sequence of events:

<div align="left" data-with-frame="true"><img src="/files/DEXChTIzOgNb4eI0Q6r8" alt="" width="375"></div>

### Performance Data

Click, install and conversion data will all be attributed to the time of click, Oct. 1st.

### Billing Data

Click, install and conversion data are attributed to the time each event occurred, Oct 1st, Oct. 5th and Oct. 10th respectively.

## When Should I View Performance Data?

* To assess how running a VCS (Virtual Currency Sale) during the weekend impacted overall revenue and user engagement.
* To evaluate the impact a specific visual change had on the user behaviour e.g. change in Offerwall elements’ color, updated top banner.
* To analyze how changing the exchange rate or the virtual currency affected performance.

## When Should I View Billing Data?

It is recommended to use billing data to track daily/monthly revenue.

## 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.digitalturbine.com/dt-offer-wall/reporting/dt-offer-wall-report-for-publishers/performance-vs-billing-data.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.
