Frequently asked questions
Elite scores F on the API Report Card. A 3E REST API is documented on the Thomson Reuters Developer Portal, covering matters, clients, time entry, rates, conflicts, and attachments. It needs 3E 2.8.1 or later; on-prem auth is per-instance Windows Authentication, and cloud credentials come only from support.
Without a usable official API, teams fall back on manual exports, file drops, or one-off vendor integrations. The other option is an unofficial API layer like Supergood that automates the authenticated web app directly.
Elite (Thomson Reuters Elite), centered on the 3E platform, is an enterprise financial- and practice-management system for law firms.
Legal Practice Management, Typically for mid-size to large/enterprise law firms needing integrated legal financial and matter management. Law-firm finance and billing teams run the GL, time-and-billing, AR/AP, rate and matter management, conflicts, and financial reporting; the system is the firm's financial system of record, integrated with CRM and DMS tools.
An entrenched market leader in large-firm legal financial management since 1980, with a deep AmLaw install base and strong Gartner/Capterra/TrustRadius presence. Now an independent company (Francisco Partners, TPG, Thomson Reuters).

Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
Yes. Supergood maintains an unofficial Elite API and MCP server so AI agents and internal tools can read and write Elite data. See the Elite integration docs at supergood.ai/docs/elite-api.
