To invite your colleagues you need to have Superuser role. This would have been assigned to you either by your OneDome manager or by your colleague that dealt with the set-up. 

Step 1. Go to the Main Menu drop down > "Company" > "Branches & Staff"

Step 2. Choose the branch you want to invite staff to and press the button on the top-right corner which says “Invite Branch Staff”.

Step 3.  Enter the agent's email address, choose applicable roles and click "Send". Invitee will receive an email with a link which they must follow to complete registration. 

Note: an agent with the role superuser can edit company profile, invite branch staff and change agents roles.
