How do I invite my team?
Last updated: 31 October 2026 · The MargenOptimierer app is in German. Button and menu names are shown exactly as you see them, with the English meaning in brackets.
You invite colleagues with their email address and decide which role they get. The invited person gets an email with a link that's valid for 7 days, and only becomes a member of your company once they accept the invitation through it. The owner and the Admins can invite, and they can give any role, including Admin. A member costs nothing extra, because the price depends on the revenue of your OTTO accounts.
How it works
- Open Einstellungen (settings) and there the Einladungen (invitations) tab. If the tab is missing, your role doesn't allow you to invite anyone.
- Click Einladen (invite) at the top right.
- In the window, enter the E-Mail-Adresse (email address).
- Choose the Rolle (role). Below the selection it says what that role can do.
- Click Einladen in the window.
Example: Inviting a colleague
On 27 October 2026 you invite your colleague at lena@beispiel.de with the Mitarbeiter (staff) role. The invitation is valid until 3 November 2026. Lena clicks „Einladung annehmen“ (accept invitation) in her email, sets a password of at least 8 characters and clicks Beitreten (join). She then works in your company with the Mitarbeiter role. What this role can do is covered under What can each role do?
When the invitation doesn't arrive
Expired or not arrived
In the list of invitations, the Gültigkeit (validity) column shows until when an invitation is valid. The Versand (sending) column shows whether MargenOptimierer has sent the email. Erneut senden (send again) in the row's menu sends the invitation out again, and the 7 days start over. Zurückziehen (withdraw) makes it invalid.
The same address again
If you invite an address that already has an open invitation, no second one is created. The open invitation gets the new role and a new link, and its 7 days start over.
If they already have an account
If the invited person already has a MargenOptimierer account for this address, they enter their existing password when joining. If they're currently signed in with a different address, they sign out first.
