# Get total monthly user count across customers

As a Reseller you get the total monthly user count across all companies you manage for billing or capacity reporting. Use a credential with Client Role = **Reseller**. Call company search (with a month parameter if the API supports it for Monthly Users), then sum the **monthly user** value from each company in the response. Paginate through all pages to include every company, or export to CSV/Excel and sum the monthly user column client-side.

***

## POST /api/companies/search

Returns a paginated list of companies; each item includes a **monthly user** count for the selected period. Request body: see Endpoints → **Company** (e.g. month selector or date range if available for Monthly Users). To get the total monthly user count: call search with a large `pageSize` or loop through all pages and sum the monthly user field from each company. The response total count and items give you the full set to aggregate.

> Retrieves a list of all companies with license details, including monthly user count per company. Sum the monthly user values across all pages to get the total for 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://doc.keepnetlabs.com/api-reference/reseller/billing/get-total-monthly-user-count-across-customers.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.
