# Generate Bill
## Overview
The **Campaign Supervisor Flow** is designed to streamline the management of attendance registers and bill generation processes for supervisors overseeing specific projects and boundaries. This flow ensures efficient selection, filtering, and approval of registers and simplifies the generation and tracking of bills. It focuses on clear workflows, actionable feedback, and validation mechanisms to enhance usability and accuracy.
## **Features**
* **Project and Bill Aggregation Selection**: Supervisors select a project and boundary aggregation level to narrow down the scope for attendance registers and billing.
* **Registers Filtering and Bill Generation**: Enables supervisors to filter registers based on boundaries, view attendance data, and generate bills only when all registers are approved.
* **Bill Management (My Bills)**: Provides a centralised view of all generated bills, with tools for searching, filtering, and downloading them in preferred formats.

## 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.digit.org/health/ph-v1.7/design/architecture/low-level-design/services/generate-bill.md?ask=&goal=
```
`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.
