Supplement Tracker manages insurance supplements for roofing contractors. Contractors create and track supplements through workflow stages from draft to sent, in review, and approved or denied, organized by insurance carrier and claim job. Supplement letters go to adjusters by email, with inbound replies received via webhook and kept in message threads, and AI provides supplement review, message classification, and draft replies. Automated follow-up sequences, escalation triggers, and homeowner notifications keep claims moving, and the app supports supplement images with annotations, a building code requirements library by jurisdiction, templates, CSV and PDF export, an analytics dashboard, two-factor authentication, and audit logging for compliance.
