What It Does

Legal Tracker is Thomson Reuters’ e-billing, matter-management and spend-management product for corporate legal departments. It is part of Thomson Reuters. It handles outside-counsel e-invoicing (including LEDES formats), compliance and anomaly checks on invoices, matter templates for areas such as litigation, contracts, employment, IP and investigations, plus spend analytics and benchmarking. It was formerly known as Serengeti Tracker. A higher tier, Legal Tracker Advanced, adds custom reporting and additional workflow automation.

What We Found

The product is documented on Thomson Reuters’ own product pages across multiple regions (US, UK, MENA) and carries reviews on Gartner Peer Insights. It is a long-established corporate legal-ops e-billing tool. Detailed firmographics roll up to the parent, Thomson Reuters.

What We Haven’t Verified

  • LinkedIn follower count — the product has no confirmed standalone showcase page; the figure in frontmatter is an apportioned [APPROX] estimate (see source note).
  • Pricing — not published; enterprise sales/contact required.
  • Independent client counts and the “most widely used” positioning — vendor-stated, not independently confirmed.
