Connects with Thomson Reuters tools like UltraTax CS and CS Professional Suite - Includes document management, time and billing, and a client portal in one place - Helps streamline routine work like generating invoices and tracking time on client projects - Pulls client emails, tasks, and notes into one shared workspace your whole team can see - Strong workflow automation that handles repetitive tasks and keeps deadlines on track - Gives clear visibility into job status, owners, and upcoming work across the firm Cons What we dislike about Onvio and Karbon: - Users report slow performance, frequent downtime, and syncing issues between modules - The interface feels unintuitive with a steep learning curve and limited customization - Support wait times are long and technical issues often go unresolved, users say - Initial ramp-up takes real time, and new users find it tough to learn at first - Setting up templates can be tricky, which slows down workflow standardization - Occasional bugs show up, especially in newer time and billing features ### Our Review **Bottom line:** Onvio and Karbon both target accounting firms, but they fit very different setups. Pick Onvio if you're already running Thomson Reuters tools like UltraTax CS or CS Professional Suite. Pick Karbon if your priority is workflow automation, email-driven collaboration, and clear visibility across jobs. Onvio's biggest draw is that it sits inside the Thomson Reuters ecosystem, so client data and tax work flow between products without manual handoffs. Users like the document sharing and built-in time and billing, but reviewers also report slow performance, server errors during tax season, and a client app that confuses end clients. Karbon takes a different angle. It pulls email, tasks, and client notes into one place so your team isn't bouncing between inboxes and a separate practice management tool. Users praise the workflow automation and the visibility it gives managers over deadlines and job status. The tradeoff is a steeper initial learning curve and some template setup friction. On pricing, Onvio starts at $50 per month and Karbon starts at $59 per user per month. The billing units are different, so the right pick depends on team size and how you want to budget seats. If you're a smaller firm deeply tied to Thomson Reuters tax products and want one connected stack, Onvio is the natural choice. If you're a growing or distributed firm that lives in email and needs strong workflow automation, Karbon is a better fit, even with the upfront ramp. ### User Sentiment Summary Onvio has a user sentiment rating of 70 based on 12 reviews.
