CarbonInvoice: Why is it the #1 User-Rated Sustainability Xero App?

We recently analysed customer reviews from small and medium businesses using carbon management and action tools, and the insights reveal a fascinating story about the gap between what providers think businesses want and what they actually need.
When we dove deep into customer feedback, one theme emerged: small and medium businesses are abandoning sustainability initiatives not because they lack environmental values, but because existing solutions demand too much of their time and resources.
Customers consistently described other solutions as requiring "pages of Excel spreadsheets and calculators," "overwhelming calculations," and "admin-heavy programs" with manual adjustments and complex data entry. One customer summed it up perfectly:
This sentiment appeared repeatedly across reviews—the perception that carbon management is inherently complex has become a significant barrier to adoption, even as the importance of sustainability in business continues to grow.
The landscape of business sustainability practices has shifted dramatically in recent years. What once seemed like a "nice-to-have" initiative for large corporations is now becoming essential for small and medium businesses across Australia, the UK and New Zealand. But here's what might surprise you: SMEs aren't avoiding carbon management because they don't care about sustainability—they're avoiding it because most solutions are unnecessarily complicated, time-consuming, and overwhelming.
Perhaps the most striking finding from our analysis is that 89% of customers specifically mentioned ease of use as a primary factor in their decision. This isn't just about user interface design—it's about fundamentally rethinking how carbon management fits into busy business operations.
Customers consistently used words like "deceptively easy," "super simple," and emphasised solutions that work in "minutes not hours." When they talk about "easy," they're not asking for dumbed-down features—they want solutions that handle the complexity behind the scenes so they can focus on running their business.
68% of reviews highlighted the importance of time-saving automation. SMEs want what customers describe as a "done for you" approach—carbon management that works "on autopilot" without requiring ongoing attention or manual work.
This automation isn't just about convenience; it's about removing the friction that causes good intentions to fall by the wayside. When carbon management requires ongoing attention and manual work, it becomes another item on an already overwhelming to-do list.
57% of customers mentioned the importance of instant visibility into their carbon footprint. Small and medium businesses don't have months to invest in understanding their environmental impact—they need results immediately to justify the investment of time and resources.
The CarbonInvoice app has been successful in providing a carbon measurement tool that customers describe as delivering a "clear understanding within minutes," transforming carbon management from a long-term project into an immediate business capability.
For SMEs already managing their finances through platforms like Xero, seamless integration isn't just convenient—it's essential. 72% of customers specifically praised smooth integration, with many describing it as "flawless" and "seamless."
This integration solves a crucial adoption barrier by embedding carbon tracking directly into existing workflows rather than requiring businesses to adopt new processes or platforms.
An important finding was how strongly customers responded to real, tangible environmental impact. 51% of reviews mentioned the importance of funding actual tree planting rather than purchasing abstract carbon credits.
This preference for tangible, local impact over carbon offsetting tells us something important about how SMEs think about environmental responsibility. They want to be able to explain their carbon action in simple terms to their team, their clients, and their community. "We plant trees" is a lot easier to communicate than "We purchase verified emission reduction credits."
Taking real and tangible environmental impact one step further, CarbonInvoice partners with businesses to co-host planting action days. During these events, participants spend the morning planting actual native seedlings in their local communities with their teams and customers. These Planting Action Days enable a direct, hands-on connection to their environmental impact.
Here's what one of co-hosts has to say:
Wellington, Auckland, and Christchurch are hot spots for Planting Action Days. With the planting sites being local, anyone can pop by and be proud of their actions.
Perhaps most importantly, businesses are discovering that understanding sustainability reporting and taking action isn't just about compliance or values—it's becoming a competitive differentiator. 19% of customers explicitly mentioned using their carbon action to win business, with several describing how it helps them appear as the "superior choice" to environmentally conscious clients.
The reviews reveal several factors driving this shift toward sustainable business practices:
What's particularly interesting is how businesses are using their carbon action strategically. Rather than viewing sustainability as a cost centre, forward-thinking SMEs are discovering it helps them:
Small and medium businesses want to act on climate change, but they need solutions designed for their reality: limited time, existing workflows, and the need for immediate value.
The businesses succeeding aren't necessarily the most environmentally passionate—they're the ones who found solutions simple enough to implement without disrupting their core operations.
For SMEs considering their sustainability journey, the message is clear: measuring your carbon footprint isn't about becoming an environmental expert. It's about finding tools that handle the complexity so you can focus on what you do best—running your business.
The CarbonInvoice App is built for professional services businesses with up to 100 ftes to measure their business' carbon footprint, mitigate the carbon emissions by planting native trees in their community.
