CHICAGO, Nov. 10, 2026 /CourierPR/ -- Harbor, the leading provider of professional and technology services to the legal industry, has acquired AAC Consulting, a specialist consulting firm focused on Aderant financial management systems. The acquisition deepens Harbor's ability to advise, implement, and manage the financial systems that run a law firm's revenue cycle, from time entry and billing to collections and profitability.
AAC Consulting, founded in 1996, has supported more than 300 law firms and professional services organizations over the years. Its consultants are known for practical, tailored solutions to complex problems, particularly for large, multi-office, and multi-currency firms. Since 1996, AAC has provided services including system assessments and planning, implementations and project management, upgrades and moves to Expert Sierra, Aderant's cloud platform, data conversion and merger-related systems work, custom development and integrations, testing, and post-implementation support.
According to the 2026 ILTA Technology Survey, most firms have moved email and document management to the cloud, but only 60% have done the same for time and billing. The largest firms are furthest behind, with one in five planning to replace their time and billing system within the next year. For the many firms still running Aderant on their own servers, that means now deciding when and how to move to Expert Sierra, Aderant's cloud platform, while also managing upgrades, mergers, and rising demand for better financial data. The work is technical and high-stakes, and the people who know these systems well are hard to find.
AAC Consulting is the fourth acquisition Harbor has completed since receiving a majority investment from BayPine LP, a private investment firm specializing in digital transformation in market-leading businesses, in June 2025. AAC adds to Harbor's Aderant work alongside iTrain, which Harbor acquired in June 2026.
Harbor, with a global team of nearly 1,000 professionals, works with more than 80% of Global 200 law firms and close to 600 corporate law departments to optimize performance and enable business and digital transformation. Headquartered in Chicago, the company has offices in London, Belfast, Moncton, and Sydney. Harbor, a BayPine LP portfolio company, is advancing its next phase of growth by broadening its technology, data, and managed services capabilities across the legal sector.
