Karbon Overview
Karbon is a collaborative work-management and practice-management platform built specifically for modern accounting, bookkeeping, and advisory firms. It unifies client email, workflows, tasks, document requests, and team communication in a single workspace so accountants stop drowning in Outlook threads and spreadsheet trackers. Co-founded in 2014 and now used by more than 7,000 firms across 40+ countries, Karbon has become the category standard for firms that have outgrown generic project tools but don't want the cost or complexity of legacy practice-management software.
Karbon's edge is that it was designed from zero for accounting firms rather than retrofitted from generic project software. Email triage, client tasks, and workflow automation are all accounting-specific, and Karbon AI is trained on the language of engagement letters, tax returns, and client advisory conversations — not generic office tasks.
