What it does
Karbon organizes accounting-practice tasks, clients, documents, communication and billing. Its tools connect work status with the people and records involved. Paid practice subscriptions distinguish team size and billing features.
Karbon keeps a client conversation close to the work it concerns. In Triage, an email can be assigned to a colleague, discussed through internal comments, added to existing work or turned into a task. Client timelines retain that context when someone else picks up the job. Shared Triage covers firm addresses, while delegated access lets a colleague help manage an individual's inbox.
Document requests, reminders, time tracking and billing sit alongside that communication. A firm can use the work record to follow responsibility and progress, then connect recorded time with the client engagement. The useful choice is how much follow-up and task automation the practice needs.
Plans and billing
| Plan | Per user/month, annual billing | Per user/month, monthly billing | Distinction |
|---|---|---|---|
| Team | US$59 | US$79 | Core work, email, time and billing tools |
| Business | US$89 | US$99 | Automated client reminders, task automation and more integrations |
| Enterprise | Quote | Quote | Custom configuration and higher usage allowances |
Monthly subscriptions require at least four team members. Every invited team member is billable. Electronic-signature credits and payment-processing charges can add to the subscription; signatures on engagement letters do not consume those credits.
A product tour or sales demo provides an introduction before purchase. The platform has an API for custom connections. Karbon's Kai assistant is advertised as an early-access feature, so teams assessing it should distinguish that access from the established Triage and work-management tools.
