Karbon
Practice management software for accounting firms: email, workflow, client portal and billing in one place, from $59 per user per month.
Karbon is practice management software for accounting and bookkeeping firms that links shared email to jobs, workflows, billing and a client portal. It suits firms with several staff handling recurring client work. Team costs $59 per user per month billed annually ($79 monthly), and there is no self-serve free trial.
A strong pick for growing firms that live in email; small or solo practices can start cheaper elsewhere.
A cloud practice management system that turns an accounting firm's shared email into tracked work, with billing and a client portal attached.
Karbon suits firms where client email drives the work and several people touch each job. Linking inbox, workflow and billing removes a lot of chasing. The catches are cost and access: it is priced above Financial Cents and Jetpack Workflow, automation sits in the Business plan, monthly billing needs 4 users, and there is no self-serve trial.
It joins email, workflow, client portal and billing for accounting firms and connects to the main ledgers.
Higher per-user price than close rivals, automation only on Business, and demo-only access.
