# CSRD Supply Chain Module

> End-to-end ESG data collection from your supplier base for CSRD reporting.

This page provides a feature overview. For full documentation, see the [CSRD module section](/csrd/overview).

## What it does

The CSRD supply chain module automates the most time-consuming part of CSRD reporting: **collecting ESG data from your suppliers**.

Without automation, this requires:

* Manually emailing hundreds of suppliers
* Following up repeatedly
* Manually entering responses into spreadsheets
* Calculating Scope 3 emissions by hand

Matproof replaces all of this with an automated workflow.
