Make them a company administrator. A company administrator's permissions apply to every club in the company. If you are already a company administrator with the Administrators permission, you can add others yourself.
Add a company administrator
On the Dashboard, click your company.
Go to Settings → Administrators.
Click Add administrator.
In Find Nettla user, type their name and click them.
Under Permissions, untick anything they should not have. All permissions are ticked by default.
Click Save.
The person must have a Nettla account and be on your company's player list. They get an email with a Manage your company button and log in at operator.nettla.co.
Good to know
The first company administrator is set up by Nettla. Contact Nettla if your company has no company administrator yet.
Company permissions work the same way as club permissions. Each box gives view and edit access.
To give someone access to one club only, add them as an administrator inside that club instead.
