Leave FileCabinet CS behind, cleanly.
FileCabinet CS reaches end of life on December 31, 2027. Denari is the industry’s leader in smooth FileCabinet CS migrations, moving your documents, structure, and history into a modern platform built for accounting firms.
The clock is running on FileCabinet CS.
After December 31, 2027, Thomson Reuters will no longer provide updates or support for FileCabinet CS. Moving your firm and client data to a modern system before then protects your practice, and the sooner you start, the calmer the transition.
What you move up to.
AI-powered organization
Firm-defined attributes are auto-applied at intake, so files arrive where they belong instead of waiting to be filed.
Full-text & AI search
Find any document by its contents, not just its filename or folder. Answers you can trust, sourced from your files.
One connected home
Every document your firm receives, manages, and delivers in one place, reachable by partners, staff, and clients alike.
A migration done with you, not handed off.
Assess
We inventory your FileCabinet CS drawers, folders, and document attributes so nothing is missed and the structure is understood before anything moves.
Migrate
Documents, folder structure, and metadata move into Denari with their integrity intact. Your history comes with you, cleanly organized.
Go live
We train your team, verify the migration together, and cut over with zero downtime for document management at your firm.
Catch up
Because the migration runs in two phases, a final catch-up pass brings over anything that changed along the way, so the cutover stays clean and nothing is left behind.
Support
Real US-based people stay on hand after go live. Questions get answered fast, by humans who know accounting.
