Layout and navigation: A fixed left sidebar holds the workspace switcher (Acme Cloud Corp, Enterprise Plan) and the main navigation: Dashboard, Analytics, Customers, Subscriptions and Invoices. Integrations and Settings sit under a separate Configurations group. At the bottom are an API usage meter (84.2% of the monthly quota) with an “Upgrade Quota” call to action, and the user profile. The top bar has global search with a ⌘K shortcut, a date-range filter, Export, notifications and a primary “Add Customer” button.
