Each client login is set screen by screen: hidden, view-only, or allowed to make changes. Out of the box a client can work in their Dashboard and can view their business details, content, reviews, reports, competition and images. Automation, billing, users, white label and other settings stay hidden.
Because approving content lives on the Dashboard, a client with the default permissions can approve or reject what's written for them. If you'd rather approve everything yourself, make their Dashboard view-only and they're told that their account manager handles approvals.
A client login can be limited to particular businesses or given every business, now and in future. Your own team gets staff logins that see every business, and administrators decide who has access to what.
