Introduction
Legal billing has always been a challenge—manual processes, complex client guidelines, and the constant demand for accuracy make it a source of stress for law firms and corporate legal departments alike. Today, artificial intelligence (AI) is transforming this landscape. Drawing on real-world case studies and industry data, here’s how AI is delivering measurable value in legal billing—and what that means for firms committed to innovation.
The Legal Billing Challenge
Law firms face a maze of client-specific billing rules, alternative fee arrangements, and ever-increasing demands for transparency. Traditional, manual approaches are time-consuming and error-prone. The result? Disputes, write-offs, and strained client relationships. AI is stepping in with practical, proven solutions.
