Our customers tell us this is why they choose Sumday. You can start a trial or book a demo to instantly see how we’re different too - showing is better than telling.

We Focus on Trusted Accounting

Sumday is accounting software for carbon, rather than ESG software trying to do accounting. If you know, you know. With a focus on trust, accuracy, and reliability, Sumday takes a common-sense approach to detailed carbon accounting. If you’re getting your finance team or advisors involved, they’ll thank you for using Sumday, it’s designed for them to elevate carbon accounting to the same level of robustness and transparency you expect of financial accounting. That’s why we’re used by more accounting firms than any other platform.

Unmatched Transparency and Control

Sumday provides the flexibility to track emissions as granularly as you need—by department, site, project for example. With complete transparency and control over your data, there are no hidden formulas or “black box” calculations; you know exactly how your emissions data is derived and we make it easy to explain that to your team and stakeholders too, in plain language.

Monthly Carbon Accounting, Not Just Once a Year Reports

Built for real-time, monthly carbon accounting, Sumday easily integrates into your normal business operations. Say goodbye to looking backwards once a year to produce a PDF report that sits unread—Sumday helps you keep a continuous pulse on your carbon impact, making it accessible to each department and actionable year-round. Easily do the groundwork to move towards carbon budgeting and forecasting, if you’re into that (who isn’t).

Support You Can Count On

With deep roots in accounting and audit across a range of industries, our support team really knows their stuff - you’re talking to accountants who understand carbon accounting. We’re safe hands for your team as they start to embed this kind of accounting, often for the first time.

Education Focused Scope 3 Solutions

Sumday goes far beyond the standard practice of sending forms to suppliers for Scope 3 reporting—especially when many suppliers struggle to answer those questions accurately. Our platform empowers you to build capacity across your entire supply chain, portfolio companies, or customer base, enabling reliable emissions reporting that integrates seamlessly into your own Scope 3 accounting.

With Sumday, every company you engage with receives two months of free access to education, enterprise-grade accounting software, and dedicated support as part of your subscription (increase this period if you wish). This means you can take immediate action to start shifting from industry averages to actual data, driving meaningful progress in emissions reduction at every level.

For Advisors - we’re not competing with you

Many platforms claim to be for advisors, yet their teams are often made up of consultants charging for services rather than focusing on the carbon accounting software itself. At Sumday, we think that’s a little off-track. We don’t compete with you for client relationships or bill high fees for consulting; instead, we’re here to support you behind the scenes whenever you need us. You’re in control—you lead the client relationship, implement Sumday as you see fit, and handle the accounting in the platform on your terms. With Sumday, there’s no need to worry about competing interests or hidden service charges; our focus is purely on empowering you with the best tools and education to succeed.

Yes, it’s called the GHG Protocol and Sumday is built on this.

You can learn more about it here.

Helpfully, nearly all global standards for climate related reporting refer to the GHG Protocol for the carbon accounting and reporting (global cohesion in standards, now that’s sumthing different).

They’re not perfect (find us an accounting standard that is). For now, if you find there’s gaps for your industry in the method or approach for a certain aspects of your accounting, it’s about making reasonable assumptions, disclosing them and staying consistent. Sumday’s tools can help you with that.
