Owners and administrators of accounts can add as many sites as needed. Staff members may have multiple sites added to their user within one account.
If you are an owner or admin, below is how to add a new site to your account.
From the Main Menu > look for "Sites".
Once on the site page, you may see a list of previously added sites or nothing at all.
Clicking on a current site name allows you to edit the site. Click on the + at the top right of the page to add a new site.
Enter the site details and click "Submit". Now, this site will be available to all admins of the account. Staff members will need this site added to their user.
After the sites have been created, adding employees will be the next step.
