What do Karbon customers say?

"Karbon has become the backbone of our accounting firm’s workflow." — Varun Sehgal, Partner, Small Business

"Karbon is one of my absolute favourite apps and has changed my business." — Heather Kennedy, Founder, Small Business

“We used to have email, contacts, time tracking, task management and tax practice management all in separate softwares. I was checking everywhere constantly to see if I’d missed a comment or task, but now [with Karbon] I don't have to do that anymore!” — Alicia Gates, Director of Systems, Mid-Market

“Karbon has solved our biggest challenges with visibility, communication, and time management. Before, we relied on scattered emails, spreadsheets, and manual tracking, which often led to missed details or duplicate work. Now, everything is centralized—tasks, deadlines, and client communication are all in one platform. This has streamlined our workflow, made it easier to track time accurately, and given our team confidence that nothing is slipping through the cracks. As a result, we’re saving hours each week, improving client response times, and keeping projects moving smoothly.” — G2 user, Small Business

“Karbon has enabled us to be more efficient, productive and profitable." — Paul Sweeney, Director, Small Business

“I cannot say enough about Karbon Support, from monthly meetings with our CSM to one off requests I have always felt the love! Outside of the application, Karbon's online Community, Magazine, Resource Library and Webinars are top shelf. I am always learning something and not only about the product, the topics are diverse and useful.” — Victoria Peters, Chief Financial Officer, Mid-Market
