The administrator portal offers much more.
The ista administrator portal acts as a central hub for property managers and offers a user-friendly interface for managing all aspects of energy management for each building. The administrator portal provides property managers with a comprehensive digital platform for easily arranging consumption-based billing. You can quickly and easily enter or update resident data, record changes and adjust energy tariffs. In addition, you can monitor the consumption data of all your properties in real time.
The portal also provides an overview of the progress of cost allocation and billing per property and the ability to view and export measurement data for reporting and analysis. Another important feature is direct access to your contracts with ista for each property. Working digitally reduces paperwork and saves time. All this makes energy management more efficient, transparent and user-friendly for administrators.
