Troubleshooting

We're asked for papers and we're not their supplier

Reply that it is not yours. One line, and it stops someone waiting for something that will never arrive.

Updated on 13/08/2026

**Reply with one line saying it is not yours and leave it there.** No need to investigate where it came from or to apologise: the sender needs to know in order to fix it, and until they do they will keep waiting.

The three reasons it reached you

What happenedWhat to say
Similar names got confused«We are not that company» and, if you know, which one is
You worked with them years ago«We have had no relationship since X»
Someone mis-copied a detail from a list«This is not ours». That is enough

Important

**Even if it is not yours, if the message carries another company's information it is worth saying so.** A list with details that are not yours, an attachment belonging to a third party: that is a mistake they will want to hear about before anyone else does. Saying so costs the same single line and leaves you in a very good light — and saves someone a problem considerably worse than yours.

What not to do

Watch out

Before writing it off as an error, check one thing: **it may be yours and you not know it**. A client who knows you under another trading name, a site you entered as a subcontractor's subcontractor, an order handled by someone else at your company. A two-minute internal call before replying «that is not us» avoids the awkward case of denying a relationship that does exist.

Do I have to reply if it is not for me?

You are not obliged, but one line closes the matter for everyone.

What if they insist afterwards?

Repeat it once in writing. That makes it clear and documented.

They sent me another company's data

Tell them. It is a mistake they will want to know about at once.
