The Verdict
Clio is the clear choice for small to mid-size firms prioritizing ease of use, transparent pricing, and modern cloud features at $39-129/user/month. Thomson Reuters makes sense only for large firms or corporate legal departments that need enterprise-grade legal research, complex workflows, and can justify the significantly higher cost and implementation complexity.
How to switch from Thomson Reuters to Clio
- 1Export your data from Thomson Reuters: use Firm Central's data export tool to download contacts and matters as CSV files and documents as a ZIP archive, or request a full data extract from your account manager if you're on 3E or another enterprise product.
- 2Sign up for Clio and use the Data Import Wizard to upload your CSV files for contacts, matters, and time entries, mapping fields to Clio's schema during the import process.
- 3Upload exported documents into Clio's document storage (or connect Clio to Dropbox/OneDrive/Google Drive) and organize them by matter to rebuild your file structure.
- 4Recreate integrations you relied on in Thomson Reuters — connect QuickBooks or Xero for accounting, add Fastcase if you need legal research inside Clio, and set up e-filing integrations available in your jurisdiction.
- 5Rebuild billing rules, time tracking templates, and any custom workflows manually in Clio, since these don't transfer automatically during import.
- 6Run a parallel period with a small pilot group logging time and billing in both systems for 2-4 weeks, then cut the full team over to Clio once billing and reporting match up.
Thomson Reuters vs Clio: common questions
How do I export my data from Thomson Reuters to move to Clio?+
If you're on Firm Central, use its built-in data export tool to pull contacts and matters as CSV files and documents as a ZIP archive. For 3E or other enterprise Thomson Reuters products, you'll need to request a data extract from your account manager or IT admin since bulk self-service export isn't always available. Ask specifically for matter, contact, time entry, and document data in CSV/ZIP format so it maps cleanly to Clio's import templates.
What features will I lose switching from Thomson Reuters to Clio?+
You'll lose direct Westlaw access unless you keep a separate Westlaw subscription or add Fastcase inside Clio, which has a smaller case law database. You'll also lose deep court-system integrations and enterprise-grade document version control, since Clio's document tools are simpler and built for smaller firms.
Is Clio's free trial enough to test with my whole team?+
Clio doesn't offer a permanent free tier, only a 7-day free trial, which is tight for testing migration with a full team and real client data. Most firms use the trial to check the interface and core billing/time tracking workflows, then run a paid pilot month with a small group before full rollout.
Does Clio integrate with the same tools as Thomson Reuters?+
Clio has a broader marketplace of 200+ third-party integrations (QuickBooks, Xero, LeanLaw, Microsoft 365, Dropbox), while Thomson Reuters integrations lean toward enterprise court and research systems. You'll likely gain more general business app integrations but lose specialized court-filing and enterprise research connections that Thomson Reuters offers natively.
Is Clio actually cheaper than Thomson Reuters over 2-3 years?+
Yes, for small to mid-size firms — Clio's published pricing tops out around $129/user/month, while Thomson Reuters enterprise plans typically start above $100/user/month before add-ons like Westlaw research fees. Over a 2-3 year period a 5-person firm can save tens of thousands of dollars, though you should factor in the Fastcase add-on (~$59/month) if you need case law research in Clio.
