Editor's takeKarbon's Triage system treats incoming email as an actionable workflow item instead of a separate inbox, and Karbon reports this saves employees an average of 18.5 hours a week. It has topped G2's accounting practice management category for 17 consecutive quarters and holds SOC 2 Type 2 certification. The web app draws praise as simple and easy to use, but the mobile app has consistently poor App Store reviews citing crashes, blank screens, and login loops, and pricing starts at $59 per user monthly, a premium rate versus modular alternatives.
How much does Karbon cost?
The Team plan is $59 per user per month billed annually, and the Business plan is $89 per user per month. Extra fees apply for add-ons like eSignature credits and payment processing, and pricing requires a custom quote for larger firms.
Is Karbon's mobile app reliable?
Not consistently. App Store reviews describe issues like blank screens when opening cases, notifications that do not lead anywhere useful, and repeated login prompts. The web platform is rated far more favorably for day-to-day usability than the mobile companion app.
