It all starts with certified submeters for heat, cooling, electricity, and water, professionally installed by our specialists. After installation, we handle everything—from data collection and validation to tariff application and precise final billing.

How we turn a time-consuming process into a user-friendly experience.

Accurate monitoring and easy access to data.

Precise multi-utility billing starts with accurate measurement of consumption. Using smart submetering for heat, water, cooling, electricity, and gas, we track individual usage in every home or unit. This data is periodically transmitted to a central system, eliminating manual readings and providing reliable consumption insights.

With this monitoring service, residents can easily access their usage data through a user-friendly web portal and app. This transparency not only helps them track monthly consumption but also identify potential savings. ista ensures fair and efficient billing, enhancing resident satisfaction.

The technology behind transparent billing.

Our comprehensive solution for multi-utility billing is built on advanced measurement and smart integration. We provide high-precision meters for heat, water, and electricity, available in both wired and wireless versions to ensure accurate and reliable consumption monitoring. All our flow meters are MID-certified. Our billing system automatically processes this data to generate precise bills with transparent, itemized costs and rates.

We can also integrate existing gas and electricity meters into the measurement infrastructure using the ista Pulsonic, provided they have a pulse output, an M-Bus or Modbus protocol, or an EAN code. Through our Administrator Portal, heating, water, gas, and electricity costs can be seamlessly managed in one place, significantly reducing your administrative effort.
