The Software-as-a-Service solution for energy sales

Joules is the only holistic ERP system for sales and marketing processes specifically designed for the energy industry. With Joules, you digitise your sales department, automate all your sales channels and thus scale your entire sales strategy.

Complete Solution for Digitization

In cooperation with basic suppliers, newcomers or established national energy supply companies, we develop a suitable digitization strategy for all their sales processes. Thanks to the integrated IT infrastructure, you no longer need to rely on isolated solutions consisting of energy CRM, customer portal, Excel lists, and manual processes.

Process Automation for Energy Suppliers

Joules automates all sales processes within the energy industry: Less manual work leads to fewer errors and more satisfied customers. You gain more time for customer service and the expansion of your marketing channels. Especially municipal utilities and smaller suppliers benefit from this proximity to their customers.

Scalability for The Energy Industry

Joules offers you a modular system solution for your electricity and gas sales. Exploit the potential of your sales channels and automate recurring, labour-intensive processes. That way, you can react more quickly to market changes and stay in the lead even under intense competitive pressure.

The Only Integrated Solution
for Energy Distribution.

Sustainable scalability through automated data processing

Noticeable relief for your employees’ everyday workflows

Individual service through your personal advisor

Energy Sales are Only Truly Scalable
with an Integrated Platform.

Thanks to the modular structure of Joules, energy supply companies are highly flexible when opening up new distribution channels. For example, municipal utilities and basic utilities often start with classic direct sales and only slowly open up to online sales channels. Newcomers in the energy sector, on the other hand, usually rely on websites and comparison services right from the start. Thanks to its modular system, Joules enables energy suppliers to add new modules whenever new sales channels are created.
