About Aderant
Aderant provides business management software for law firms, including time and billing, financial management, and practice management applications. The company traces its origins to 1975 and has operated under the Aderant name since a 2011 rebranding following its separation from CompuLaw and prior ownership structures. It is headquartered in Atlanta, Georgia, with additional offices in other regions serving legal markets globally.
The company's core product line includes Aderant Expert, used for financial and practice management, and related tools for billing, business intelligence, and matter management aimed at law firms and other professional services organizations. Aderant serves law firms ranging from mid-sized practices to large global firms, positioning itself as a provider of back-office and business-of-law infrastructure rather than document or case management tools used directly by attorneys.
Aderant has changed ownership multiple times, including a period under private equity backing, and has made acquisitions to expand its product portfolio over the years. Specific current financial details and total funding amounts are not publicly disclosed.

Competitive Landscape
Who Aderant competes with, and how they differ.
Elite's 3E platform is the closest head-to-head rival to Aderant Expert for financial and practice management inside Am Law 100/200 and global firms, competing on the same time, billing and matter-accounting ground. Elite is private-equity owned and changed hands again in 2025 when TPG agreed to sell it to Francisco Partners, whereas Aderant has sat permanently inside Roper Technologies since 2015.
Clio covers the same practice management, time tracking, billing and trust accounting workflow, but sells self-serve per-user subscriptions to solo and small firms with an app marketplace, while Aderant quotes enterprise deployments to large firms and adds general ledger, e-billing compliance and rules-based docketing that Clio does not carry.

MyCase (AffiniPay) bundles intake, case management, billing and card payments for small firms at flat per-user pricing, overlapping Aderant only on time entry and invoicing. It has no equivalent of Aderant's law-firm general ledger, outside counsel guideline compliance or Am Law-scale docketing.
1 product reviewed on TopReviewed
Docket Alarm competes with Aderant's Milana and CompuLaw docketing line on court docket aggregation, full-text filing search and case alerts, and is sold as a per-seat research tool. Aderant's docketing is a rules-based calendaring engine wired into the firm's practice management and billing system rather than a standalone research product.
