#1-ranked accounting practice management platform on G2 for 18 consecutive quarters
About Karbon
Karbon is the top-ranked practice management platform for accounting firms, holding the #1 position on G2 for 18 straight quarters through Spring 2026. The platform combines workflow management, team collaboration, client communication, and business intelligence in a single interface designed specifically for accounting and bookkeeping firms. Karbon's AI features include Karbon AI, which can draft client emails, summarize work items, and surface actionable insights from firm data. The workflow engine automates recurring tasks like month-end checklists, onboarding sequences, and tax season workflows with customizable templates. Where Karbon differentiates is in its 'Triage' system — a unified inbox that aggregates emails, tasks, and client requests into a single prioritized view, preventing things from falling through the cracks. The platform integrates with QBO, Xero, and major accounting tools.

Ledger Brief Take
Built specifically for accounting firms rather than adapted from generic project management tools, making it the rare practice management platform that understands billable hours, client deadlines, and seasonal workflow patterns. The AI features handle routine communication tasks well, though the real value lies in how it replaces the typical mess of spreadsheets, email chains, and separate task managers that plague most firms.
