About Us.

Our Vision

We see a world where accounting systems have transformed the global economy into a force for good.

So we're on a mission to empower every organisation to account for impact beyond dollars and cents, accelerating better outcomes for people and the planet.

Our Values

Grapple With the Hard 🪨
‍We deal with the hard things - the unanswered questions, the overwhelming challenges and the tough conversations. We don’t oversimplify for the sake of it, we go deep on complex problems to understand how we can truly solve them for our customers.

‍Radically Transparent 📖
‍Transparency and trust underpin both accounting systems and our relationships - it’s core to everything we do and create. We are radically transparent in the way we communicate internally and externally, even when (and especially when) it’s uncomfortable. If we stuff up, you’ll know about it.

‍In Your Shoes 👟
‍We put ourselves in the shoes of others, including our customers and teammates. We actively listen before we respond. We commit to our own personal development and growth, so we’re always capable of thinking about our actions from the perspective of those they impact.

‍Pursue Extraordinary Things 💫
‍We’re wildly ambitious, fast and efficient in the pursuit of our vision - we say what we’re going to do and we get on with it. We lead by example, holding ourselves accountable to standards we’re proud of. Everyone is empowered to pursue the extraordinary here.

‍Education First 🎓
‍Access to education unlocks true transformation - it builds human confidence to tackle the biggest problems. We share our knowledge openly, empowering others to drive change through the power of accounting systems, in a way that’s accessible to everyone.

Where it started

In 2021, Co-Founders Jessica, a lawyer, and Lindsay, an auditor, launched an accounting firm in Tasmania after spending three years in the mining industry.
‍
They wanted to seamlessly integrate sustainability into financial reporting. They believed emissions data would soon be as essential in annual reports as profit margins, and businesses would demand more than back-of-the-envelope carbon estimates.

After grappling with messy Scope 3 data, unwieldy spreadsheets, and carbon calculators that just didn't "get" accounting, they realised the challenge was bigger than their firm alone could solve.

Advisors and finance teams needed intuitive, robust software and practical education to make sustainability accounting as reliable and routine as financials.

With this vision, Sumday was born in February 2023, powered by an incredible team who are dedicated to making reliable, robust carbon accounting the new normal for every business.

Welcome to the future of accounting.
We’re so pleased you’re here.

What our investors say.

“In order to accelerate climate investment over the coming decades, we need a better approach to understand how, and precisely to what degree, these investments will reduce our emissions. We need the same rigor in carbon accounting as we demand across financial accounting as table stakes. Sumday is building the tools to make this accessible for every business.”

"Sumday have a true advantage in building a product that understands where carbon accounting is heading and who will be helping businesses grapple with the implications of it (the accountants!) We were even more excited to learn that they’re thinking even *further* ahead to take natural capital accounting into account, which will be the next important wave in addressing the impact that we all have on biodiversity and the planet.”

"Jessica Richmond, Lindsay Ellis and Danny Hoare deeply understand the future of accounting and the power that’s contained in companies’ ledgers. By changing the way our businesses reconcile their books we can drive systems change and properly incorporate the value of the natural world around us. Wedgetail is incredibly excited to be part of the Sumday journey and help to tackle climate change and nature loss with accountants everywhere!"
