Our Manifesto

  • 100% accurate

    Everyone can be more efficient

    Every organisation can do more to use less power, gas and water in ways big and small. It is important to our environment and to our shared future. SUMS is helping Australian and New Zealand organisations to do just this.
  • 100% accurate

    Efficiency is good business

    Using less power, gas and water is not just helpful, it’s good for the bottom line. Being connected to SUMS reduces your environmental footprint, saves you time and money and lets people know you are doing your best for our shared future.
  • 100% accurate

    Technology drives good business

    Technology is at the heart of what we do: as a driver of insights, as a hardware and software provider, and through the ways we connect with our customers. We believe in maintaining a cycle of continuous improvement so our technology provides the best possible outcomes for our customers.
  • 100% accurate

    People make technology work

    We help you to get to the most important work! If there are ways to automate, delegate and free ourselves up for the stuff that really matters, let’s make that happen. SUMS helps people manage complex infrastructure networks simply. This frees up time for implementing a policy to reduce electricity usage by 10% in one year or for showing the CEO how saving water saves money across APAC.

Your team infinitely better.
