Overview
Karbon is a cloud practice management platform built for accounting firms, organised around shared email, recurring work and team collaboration. The company describes a globally distributed team based in the US, Australia, New Zealand, Canada and the United Kingdom, and reports more than 40,000 accounting professionals using the product daily, customers in 40 countries and 7.95 million jobs completed by customers in 2025[2].
The product combines integrated email triage with workflow templates, to-do lists, time tracking, budgets, billing, payments and engagement letters. The Business plan adds automatic client reminders, task automation and integrations with industry software, and the Enterprise plan removes the numerical caps on statuses, templates, teams and contacts that apply to lower tiers[1]. Recent additions shown on the company’s site include an AI coworker called Kai, AI agents, close automation, payroll, and a Practice Marketplace for buying and selling firms[2].
Karbon’s pricing is published but sits towards the upper end of accounting products, and monthly billing is available only for teams of four or more on Team and Business. The Team plan caps contacts at 1,000, which matters for high-volume tax practices[1].
