Biomass Operations
Alternative Fuel Supply Chain Management Platform
A comprehensive mobile and web platform that digitizes biomass dispatch operations, cash management, and field workflows with offline-first capabilities for remote operations.
Goals
- ✓Digitize dispatch flows from creation to receiving
- ✓Track cash movements between employee wallets and head office
- ✓Reduce reconciliation time from hours to minutes
- ✓Support operations in areas with poor or no connectivity

Solution
Sitara designed and delivered a Flutter-based mobile app with a Node.js API backend and reporting console. The system supports offline capture of dispatch data, wallet transactions, and penalties, automatically syncing to the cloud when connectivity is available. Role-based access ensures appropriate permissions for field staff, supervisors, and finance teams.
Overview
A comprehensive mobile and web platform that digitizes biomass dispatch operations, cash management, and field workflows with offline-first capabilities for remote operations.
Problem
The client managed a high-volume biomass supply chain using paper slips, spreadsheets, and manual reconciliations. Field teams had no reliable offline tool, and head office had limited visibility into cash movements, dispatches, and penalty calculations. Daily reconciliation took hours and was error-prone.
