We're using Google Apps to handle our email (me@example.com), and according to Google you could set up a collaborative inbox for your business email through Google Groups (link).
But when I sign in and click the "New group" button I can just use their "@googlegroups.com" email, and for this reason the group is not at all associated to the company.
I feel like an idiot when I'm lost in a service by Google – what am I doing wrong?

To create a collaborative inbox you need a Google Apps for Work or Apps Unlimited account. You can not create a collaborative inbox with a Free (legacy) Apps account.

If your Apps user account does not have permission to create groups under your domain, you can create a group from within the Apps admin panel (https://www.google.com/a/).
