The pain of legacy tech

Billing technology should not be the thing that gets in the way of innovation, bringing clean energy products to market, customer-centricity, or even just day-to-day operations. But, often it is. And that’s because legacy energy billing systems were not designed for the decentralised, digital new energy economy.

The issue with this is that energy sellers are missing revenue opportunities, both in the development of new energy propositions as well as having the visibility of every unit of energy sold to accurately bill it.

Common challenges with legacy billing tech:

  • Bringing new propositions to market quickly because billing software can’t be configured easily
  • Accurate, automated real-time complex calculations for products like broker commissions, VPP and PPA
  • Multi-party billing
  • Behind the meter allocations such as EV
  • Meeting ongoing and evolving compliance obligations

Modern billing technology for the new energy economy


Flux was designed with the ultimate flexibility in mind, enabling energy sellers to easily and accurately calculate and bill almost any unit of energy for mass market and C&I customers. 

From launching renewable energy products like power purchase agreements, virtual power plants, solar and battery, and EV, to automating broker commission calculations, creating dynamic tariffs, customer incentives, and rebates, these things, and more, are all easily configurable in Flux.

But it’s the end result that’s key here - adaptable energy businesses that bring innovative new solutions and attractive tariffs to market much faster than those organisations still battling with the confines of legacy billing software. And ultimately, optimised revenue with a streamlined, agile business.
