Supply Chain Supplier Engagement

Supplier engagement lets you request emissions data directly from your suppliers and track every response in one place — no more chasing spreadsheets over email. The whole workflow lives under Supply Chain in the main navigation, split across Suppliers, Tracker, Campaigns, Contacts and Form Templates.

In this article, you'll learn how to:

Add suppliers to the tracker and see every engagement status at a glance
Group engagements into campaigns with their own dashboards
Choose a ready-made form or build a custom one from the field library
Send the engagement and understand what your supplier sees

You'll need a supplier list in NetNada before you can start. Suppliers appear automatically from your uploaded spend data, so complete your data uploads first.

Step 1: Add suppliers to the tracker

Open your suppliers table

Navigate to Supply Chain > Suppliers. This lists the suppliers NetNada knows about from your data.

Add suppliers to the tracker

Click Add to tracker on a supplier row, or tick several suppliers to add them in one go. Tracking a supplier means you intend to engage them for data.

Review the tracker

Navigate to Supply Chain > Tracker. Every tracked supplier appears here with their engagement status, campaign, contacts, and a Start engagement action — so you can begin the moment you're ready.

Step 2: Group engagements into campaigns

Campaigns group related engagements together — for example, all the suppliers you're surveying for this reporting period. Each campaign gets its own dashboard showing an engagement overview, response rate, completion rate, a needs-attention panel highlighting suppliers who haven't responded, and a per-form breakdown of responses.

Run one campaign per reporting period or per supplier segment. The campaign dashboard then doubles as your progress report — you can see response rates without opening each engagement.

Step 3: Choose or build a form

The form defines exactly what you're asking each supplier for. Navigate to Supply Chain > Form Templates and either duplicate a NetNada starter or build your own from scratch.

Start from a ready-made template

NetNada includes starters such as GHG Disclosure Basic, Procurement Spend, and Logistics & Freight. Click Duplicate to edit to make your own copy and adjust it.

Or build a custom template

The form builder lets you assemble exactly the fields you want — pull common questions like scope totals, methodology and supporting documents from the reusable field library, or add your own custom inputs.

Step 4: Send the engagement and track responses

Check the supplier's contact

Manage each supplier's focal points and email addresses under Supply Chain > Contacts. The engagement is sent to the contact on record, so confirm it before sending.

Start the engagement

From the tracker, click Start engagement on a supplier, choose the form and campaign, and send. The supplier receives an email with a secure link that expires after a set window.

Track responses

Watch progress on the campaign dashboard. As suppliers submit, statuses update in the tracker and responses appear in the per-form breakdown.

What your supplier sees

Your supplier receives a simple portal form — they click the secure link in the email, fill in the requested information, attach any supporting documents, and submit. They do not need a NetNada account or any training. If they hit trouble with the link, send them this help article written for suppliers.

Once responses come in, head to the Supply Chain overview to analyse the results against your supply chain emissions.

FAQ

Do my suppliers need a NetNada account to respond?

No. The email they receive contains a secure link straight to the portal form. They complete and submit it in the browser — no sign-up, no password.

What happens if the supplier's link expires before they respond?

The secure link has an expiration window for security. If it lapses, start a fresh engagement from the tracker to issue a new link.

Can I ask different suppliers different questions?

Yes. Create multiple form templates — for example, a detailed GHG disclosure for your largest suppliers and a lighter procurement form for the rest — and choose the right one when you start each engagement.

Can I engage a supplier without adding them to a campaign?

Campaigns are the recommended way to organise engagements because they give you response and completion dashboards. Group even a handful of engagements into a small campaign so you can track them in one place.

What if a supplier says they never received the email?

First check their address under Supply Chain > Contacts, then ask them to look in their spam or junk folder. If needed, correct the contact and start a new engagement to resend.
