It goes beyond a feature toggle. Pricing Tiers/Packages tend to consist of more "sophisticated" pricing mechanisms, usually split into Licensed Features (simple toggles like SAML enabled and limits like Seat Count) and Metered Features (either quotes/limits or pay as you go). We're currently working on the metering functionality together with billing systems integration. That's the difference, IMO, from the common Feature Flags solution.
