Karbon is practice management built around the firm's inbox, on the reasonable premise that most work in an accounting practice arrives and is chased by email.
What it actually does
Email, tasks and client work sit in one place, so a job's full history is visible without digging through individual inboxes. AI features draft replies, summarise long threads and surface work that has gone quiet.
Who it suits
Firms past the point where a shared inbox and a spreadsheet work — typically five staff and up.
Where it falls short
Per-user pricing means it is a real budget line as you grow. Sole practitioners will find it heavier than they need.
What we like
- Email and workflow genuinely unified
- Good visibility of who is waiting on what
- AI summaries save time on long client threads
What to watch
- Per-user cost adds up
- Overkill for sole practitioners
- Migration from an existing system takes effort
