Do we have to rip out our supplier portal or EDI setup?

No. Mandel sits on top of the channel your suppliers already use, so it runs alongside whatever you have. Teams typically keep EDI for the high-volume partners where it already works, and let Mandel cover everything else — which is usually the long tail where the disruptions actually come from.

What do our suppliers have to do?

Nothing. There's no portal to log into, no format to adopt, no onboarding sequence to run. Suppliers keep emailing your team exactly as they do today. That's the point — supplier adoption is the step that kills portal rollouts, so we removed it.

How is this different from an EDI integration?

EDI needs both sides to agree on a structured format in advance, and it needs a mapping per partner. Mandel reads the unstructured message as it arrives — prose, PDF attachments, packing lists, quote replies — and extracts the same information without a prior agreement. When a supplier changes their format, nothing breaks.

How long does it take to go live?

You can be running the same day. Connect Outlook or Gmail and Mandel starts reading supplier threads immediately — no IT project, no API build, no training data. Compare that to a portal rollout or an EDI onboarding, which are measured in months and depend on supplier cooperation.

Does it write back to our ERP?

Yes. Mandel integrates with SAP, Oracle, NetSuite and other major ERPs, so extracted commitments and documents sync into your procurement system rather than living in a separate tool.

Is our supplier email secure?

Mandel is SOC 2 Type II compliant, all data is encrypted in transit and at rest, and we never share your data with third parties. Your supplier communications stay yours.

( COMPARISON )

Supplier portals and EDI were patches. Mandel is the fix.

Both were built to force structure onto supplier communication. Neither changed where the work actually happens — your inbox. Mandel coordinates over the email and ERP you already use, with nothing for your suppliers to adopt.

Why coordination keeps slipping through

Every tool in this category made the same bet: that if you gave supplier communication a structured place to live, people would use it. They didn't. The work stayed in email.

Supplier Portal

Last updated 47 days ago

Supplier Portals

They shift the work onto your suppliers.

A portal only reflects reality if every supplier logs in and keeps their data current. Most won't — they have their own systems and their own priorities. So your team falls back to email to get the real answer, and the portal quietly goes stale. You end up maintaining two sources of truth and trusting neither.

EDI

It breaks, and every supplier needs a rewrite.

EDI works when the format holds and the partner list is stable. Neither lasts. Every new supplier is a new mapping, every format change is a project, and when a transaction silently fails there's nothing watching. You find out mid-fulfilment, from the shortage — not from the integration.

RE: PO 22/7834 — partial shipment

from: supplier@acme-mfg.com

Hi — we can only ship 140 of 400 units this week. Balance moves to Aug 29. Also note the unit price is now €12.40.

Email & Spreadsheets

The real source of truth — and the real risk.

The delay notice, the backorder, the price that came back different from the PO — it all arrives as prose in someone's inbox. That channel has no instrumentation and no integrity: nothing checks it, nothing escalates from it, and nothing proves what was promised. Discrepancies aren't caught late so much as caught by consequence.

Mandel vs. the legacy playbook

The difference isn't features. It's where the system sits: on top of the channel your suppliers already use, instead of beside it.

Stop paying the coordination tax.

You don't need your suppliers to change how they work. You need something watching the channel they already use.
