# Supplier Onboarding
> Invite suppliers and request information
## Overview
If you do not have the required evidence on hand yourself, you can invite your suppliers directly through Polygon One. Suppliers receive secure access to a **supplier portal workspace** without having to create their own account.
## The Invitation Process
In the compliance dashboard, identify the supplier or the articles for which data is missing.
Click **"Request information"** or **"Invite supplier"**. Select the EUDR-relevant articles for which data is needed. Optionally, you can add a personal message.
The supplier receives an email with a **secure link** to the supplier portal. No separate account is required.
The supplier provides geodata, documents, and legal information through the workspace and can return later to supply any missing content.
As soon as data is submitted, Polygon One automatically performs an analysis (satellite imagery evaluation, document validation).
## Bulk Invitation
Using the **"Invite all suppliers"** function, you can invite all suppliers with an email address at the same time. Suppliers without an email are automatically skipped.
## What Suppliers Provide in the Portal
In the supplier portal, your suppliers go through the following steps:
Company name and the supplier's country or address.
Production locations are specified for each article:
* Select the **production country**
* Specify the **name of the raw material producer**
* **Draw the areas on the interactive map** or upload them as a file
* Details for the drawn production sites (production period, scientific name of the raw material, etc.)
If the supplier sources materials from additional sub-suppliers, they can invite them in the portal. Incoming articles are recorded with an HS code and article number.
Incoming articles are automatically linked to the article you imported, so that the supply chain remains traceable upstream.
A comprehensive questionnaire covering:
* Land use rights & ownership
* Environmental & nature conservation laws
* Forestry law & timber use (for wood products)
* Rights of third parties & indigenous communities
* Labor & human rights
* Tax, trade & customs regulations
* Anti-corruption measures
Evidence documents can be uploaded for each category.
## What the Supplier Completes
Via the invitation link, the supplier opens the EUDR data request form — without their own user account. The form is divided into several sections:
* **General information**: company name, address, and country
* **Geo data**: draw the production areas for each requested article on the map or upload them as GeoJSON
* **Sub-suppliers** (optional): invite additional sub-suppliers by email
* **Legal questionnaire**: answer country-specific compliance questions and upload evidence documents
The supplier can reopen the link while it remains valid to provide missing data or update their information.
The supplier upload uses the same technical review workflow as your own plot import, but with stricter supplier rules.
## FLEGT License Shortcut
For suppliers from FLEGT VPA countries who supply wood products, there is a shortcut: if a valid **FLEGT license** is available, the detailed legal questionnaire can be skipped. The license can be uploaded directly when inviting the supplier.
## Sustainability Certifications
Suppliers can also upload sustainability certifications (e.g. FSC, PEFC, ISCC, Rainforest Alliance, RSPO, Fairtrade). The system automatically analyzes which compliance categories are covered as a result.
