Carbon accounting isn’t always at the top of the to-do list. But building a values-driven, resilient business often is. And increasingly, your customers, employees and suppliers are expecting sustainability to be part of the story. 

That’s why we’re making sustainability easier to understand and act on. With Sumday, you already have estimation tools and a full carbon accounting suite. This month, there’s more for you to discover: Introducing Sumday AI, your new sustainability analyst.

Kiely Plumbing

The mission and motto of Kiely Plumbing, a third-generation, family-owned plumbing business, is “plumbing with purpose”. General Manager Sam Kiely says that their customers and suppliers are increasingly environmentally conscious and socially aware, and want to work for trades businesses who share those values. Being carbon-aware gives Kiely Plumbing a competitive edge. 

Sam says Sumday has armed him with the data he needs to make informed decisions about what sustainability initiatives have the most impact. It also helps the business meet the demands and inquiries of their suppliers asking for carbon information. 

Sumday helps Kiely Plumbing live up to its sustainability mission and influence and inspire customers, suppliers and other trades businesses to do the same. 

West Pine Ag

As carbon accounting advisor for agribusiness West Pine, Emily Roberts understands the importance – and difficulty – of transforming abstract agricultural data into quantifiable emissions metrics. Sumday allows Emily and her team to understand how cow populations, crop yields and more impact both their financial and sustainability bottom line. 

Emily says many businesses that track emissions have a lot of data, but not a lot of ability to draw insights from it. The beauty of Sumday is that it can transform everyday data from purchases and bills (and counting livestock, application of fertilizer, and cow feed) into emissions information. Plus, it then goes further to turn that data into actionable insights. 

Sumday allows West Pine to calculate what they need for their carbon inventory, find hidden efficiencies and costs, and get a clear emissions profile of various activities on the farm. 

Pinnacle Investment Management Group

For Pinnacle, the transparency around carbon accounting and sustainability data is becoming increasingly important for risk mitigation. Plus, with more and more of their affiliates demanding carbon accounting services, sustainability manager Ella Thompson needed a way to scale this area professionally and accurately.

The smooth integration between Xero and Sumday allows Ella and her team to maintain consistency in how they assign emissions factors and keep tidy, transparent records they can rely on across all of the accounts they manage. Ella especially loves the AI features, which help her categorise and reconcile up to 20,000 line items efficiently. 

Ella says Sumday is making it simple to bring people along on the sustainability journey as Pinnacle grows.
