Returned when the ADVANCED option is selected on the Tariff structure selection page. Use this to build a custom interface where your customers can define complex tariffs — including TOU schedules (e.g. weekends, seasons, special days), consumption tiers and market-based pricing. The structure and validation rules follow the create-a-tariff API endpoint. Contact support for guidance before implementing.
