Kintsugi gives your practice a comprehensive view of all required actions across every client organization: registrations, filings, nexus exposure, and pending tasks like product categorization. Add clients without adding staff.

Practice Management
Dashboard

See every client's compliance status in one place. Pending filings, registration gaps, approaching nexus thresholds, and outstanding tasks are surfaced automatically so nothing falls through the cracks across your book of business.
