Yes. One Moodiy account can manage more than one Moodle site.
Each Moodle site is attached to its own subscription or service in the client portal. That means each site can have its own plan, site URL, storage allocation, user capacity, add-ons, billing state, and support history.
Use the Moodle Sites and Dashboard areas in the client portal to switch between sites and review each subscription. When you create a new site, choose the plan and setup options for that site separately.
If you work with a team, role permissions decide which team members can view or manage each account area. If a teammate cannot see a site, ask an organization admin to review their role and organization context.
