What it is
Elite 3E is the financial and business-operations system for large law firms: time, proformas, billing, collections, general ledger, trust, matter pricing and firm analytics, with eBillingHub for client e-billing portals and Elite Payments for card, ACH and trust-compliant deposits. It is the other half of the large-firm duopoly with Aderant. Firms choosing a new financial system of record above roughly 150 lawyers almost always shortlist both.
Elite is no longer a Thomson Reuters product. TPG bought a majority stake in 2023, and Francisco Partners announced in August 2025 that it would buy Elite from TPG and Thomson Reuters. Elite now sells standalone, and its legal entity is Eagan US Holdco. Some developer documentation still tells cloud customers to request API credentials from “Thomson Reuters support,” so expect the old branding to linger in contracts and portals.
Why it shows up in Legal Ops stacks
- The cloud migration wave is running through it. Elite reported 123 firms live on 3E Cloud and 53,000 SaaS users, up 60% year over year, in August 2026. It also said cloud customers would outnumber on-premises customers by the end of 2026. Paul Hastings, an on-premises 3E firm with 1,200+ lawyers, chose 3E Cloud in January 2026. Hogan Lovells Cadwalader moved onto a single 3E environment in August 2026, about three weeks after the merger, in what Elite says was a six-month project. Fasken went live on 3E Cloud on October 13, 2026.
- New features ship to the cloud only. The February 2026 release was explicitly cloud-only: Data Connect, Elite Intelligence in Proforma, AI time capture from Microsoft Teams, and e-invoicing compliance routed through Edicom. On-premises 3E customers are now on a maintenance track in practice, whatever the support dates say.
- Data Connect makes 3E data usable outside 3E. Data Connect pushes near-real-time WIP, billing, AR and realization data into the firm’s own Microsoft Fabric tenant. Elite says pilot firms cut reporting time by 50%. That is a vendor figure, but it is the first route out of 3E that does not require custom pipelines.
Pricing reality
Elite publishes no prices, and every deal is quoted. Third-party estimates are unsourced and spread widely. ITQlick puts licensing at roughly $3,000 to $4,800 per user per year, and enterprise implementations past $250,000. LegalToolGuide quotes a 12-to-18-month migration for a mid-size firm. Read those as orientation, not a budget. The real cost drivers are the number of timekeepers, which modules ride along (eBillingHub, Validate, Payments, Data Connect), and how much on-premises customization you carry into the cloud.
Elite Intelligence (the AI in Proforma) has no separately published price. Ask whether it is in the base cloud subscription or an add-on before you count its claimed savings of up to four hours per lawyer per month of proforma review.
Best for
CFOs, billing directors and legal operations leaders at firms of roughly 150 to 2,000+ lawyers that are replacing a non-Aderant financial system, or are on on-premises 3E and need to move to the cloud anyway. It is the strongest pick for multinational firms, because e-invoicing compliance for countries such as Belgium, Poland, France, Australia and New Zealand is built in rather than bolted on.
Do not buy it for a 40-lawyer firm. Clio covers time, billing and trust at a published per-seat price. Do not buy it for a corporate legal department either. 3E bills clients; managing outside-counsel spend is a job for Brightflag or Onit.
Versus the alternatives
Aderant is the other default. Pick Aderant when you already run Expert, because Sierra keeps your database and customizations instead of forcing a re-implementation. Pick 3E when you are replacing something else and want the most large-firm cloud references and a native e-billing and payments layer. On AI, Aderant is further ahead on agents: its Agent Center entered early access with seven agents at ILTACON in August 2026. Elite’s AI today is embedded in specific screens, not shipped as agents.
Intapp is not a substitute. It runs intake, conflicts and DealCloud, and its Intapp Time integrates with 3E. Buy it alongside 3E, not instead of it.
Clio is the fastest-growing entrant moving up-market. It passed $500 million ARR in May 2026 and sells Clio Operate to larger firms. Pick Clio under about 150 lawyers, or when published pricing matters more than multi-entity accounting and cross-border e-invoicing.
If none fit, the gap is usually the layer above the ledger, not the ledger itself. Laurel or PointOne for time capture and Oddr for collections all sync to 3E and cost far less than a migration.
Watch-outs
- “Cloud-only” turns your on-premises 3E into a dead end. Guard: get Elite’s written end-of-support dates for your on-premises version and the cloud-migration price before renewal. Use the cloud quote to negotiate your on-premises maintenance, not the other way round.
- Data Connect only lands in Microsoft Fabric. A firm on Snowflake or Databricks pays for Fabric capacity it did not plan for. Guard: price the Fabric capacity in the same business case, or confirm in writing that the 3E REST and OData APIs cover the tables your warehouse needs.
- There is no official MCP server. Third-party connectors exist: one integration vendor lists a beta 3E MCP connector, and Supergood offers an unofficial one that automates the web app. Guard: connect AI tools to 3E only through the documented REST or OData APIs or Data Connect, with credentials scoped per integration. Keep screen-scraping connectors out of production financial data.
- Elite’s six-month go-live stories come with a large services team. Guard: plan for 12 to 18 months unless Elite or a named delivery partner commits to the timeline in the statement of work, with acceptance criteria for data conversion and the first month-end close on the new system.
