For suppliers

Why suppliers never log in to Cronwell

Updated August 2026

What you as a supplier will receive

Ordinary emails, from the company you already work with. A purchase order as a PDF, the way it comes today. A polite follow-up if an order hasn’t been confirmed. A question when something in a reply doesn’t match the order. Optionally, a weekly summary of your open lines with that customer, through a link to view them without signing up for any portal account.

The emails come from your customer’s buyer or from the team’s assistant address.

A normal follow-up.

What Cronwell never asks of you

  • No account and no password. There are no supplier logins in Cronwell at all.
  • No software to install.
  • No extra formatting. “PO 88213 ships March 23” in a reply is enough; so is a PDF confirmation or your usual paperwork attached to the thread.
  • No new address to whitelist and no change to how you send invoices, advance ship notices (ASNs), or anything else.

What happens to your reply

On behalf of your customer, Cronwell reads the reply, matches it to the right PO line, and proposes the update (new date, confirmed quantity, tracking number), with your email attached as the evidence. Your customer reviews and approves the update before their system reflects it, and any reply you receive was approved the same way.

For you this mostly means fewer duplicate questions. The status you already gave doesn’t get asked again by a second person, because it landed in one shared record the whole buying team sees.

Questions suppliers ask

Do I need to create an account?
No. There are no supplier accounts to create.
What if I reply in my own format, or attach a PDF?
Both work. Cronwell reads plain language and attachments, and compares them against the order before anything is proposed.
Who is actually emailing me?
Your customer. Mail comes from the buyer’s address or the team’s assistant address, with buyers’ approval.
Can we keep using EDI?
Yes. If you exchange EDI documents with this customer, nothing changes; Cronwell covers the email side of their supplier base — more on EDI here.
What does my customer see?
The status of their own purchase orders: what’s confirmed, what’s moving, what’s shipping, with your emails as the source. It is the same information you’re sending them today, kept current.

NotesDescribes supplier-facing behavior of Cronwell as deployed in August 2026: no supplier accounts; optional weekly open-lines summary with view link; outbound messages and record changes clear buyer-set approval rules; sending from the buyer’s address or the agent’s own.
