Abstract: The present invention relates to a system and method for managing operational data pertaining to a service through a distributed ledger with minimal or no manual intervention. The system enables a user and an entity (and third party for fund processing) to perform an incremental data management, rate card management that may be acceptable to both the user and entity for efficient fund processing. The system and method of the present disclosure facilitates managing operational data pertaining to service to reduce the associated costs and time related to reconciliation as well as to reduce manual verification efforts. The system also enables additional IoT based implementation that can result in fully automated system with true estimation of the energy consumption by inter communication between multiple ledger networks and IoT.
