Of course! The administrator can add a new user right from https://admin.xogo.io. An invitation can be created for new users. 

You can also do this right in the XOGO Manager app. Just click on Sign Up and enter the new @yourcompany.com email address, password, etc. You’ll see a note that your company is already registered in XOGO; please click OK to apply. Then as the admin who originally set up your company account in XOGO, you will get an email and can approve the new user yourself. Please see images below.
