Karbon
Collaborative practice management for accounting firms.
Overview
Accounting firms with five to fifty staff that still relay client context through hallway conversations and forwarded emails need a shared workspace where everyone sees the same picture. Karbon centralises client email, workflow templates, and team task tracking so handover happens in the system, not in someone's head.
Karbon is not a CRM bolted onto an inbox plug-in. It is a shared workspace where email is the spine of the work itself. The distinction matters because most practice management tools treat email as an afterthought. The job lives in a separate task system, the conversation lives in someone's personal Gmail, and the handover meeting exists to bridge the gap. Karbon collapses the gap. Client emails route into a shared workspace, attached to the client and the open job, so anyone on the team can see the full conversation, pick up where a colleague left off, and act without a briefing.
Karbon is also not a list of tasks pretending to be a workflow. Recurring jobs such as monthly accounts, quarterly reporting, or annual tax returns are set up once as templates. When the job comes around, the template generates the assigned tasks, deadlines, and dependencies in one click. Managers get a firm-wide view of what is open, overdue, or stuck, across every client, without asking for a status update.
The Business plan adds automation rules that progress jobs between stages and send clients automatic reminders when documents are outstanding. That removes the manual chasing that quietly eats into billable time across a small firm.
Karbon works with QuickBooks, Xero, Gmail, Outlook, Google Drive, OneDrive, Slack, Microsoft Teams, and Zapier. Pricing starts at $59 per user per month on annual billing. Business is $89 per user per month. Enterprise pricing is on request. There is no free trial or free tier, which matters if you want to pilot before committing. The platform serves firms in the US, UK, Australia, Canada, and more than thirty other countries.
