AI and the Future of the Billable Hour Model

The billable hour has survived decades of criticism. Generative AI may be the force that finally breaks it – but the disruption will come from inside clients, not outside counsel.

History is replete with moments when technological innovation transforms society and work. Artificial intelligence is one such moment. It is not just making the delivery of legal services more efficient; it is fundamentally reshaping what legal work is, how it is delivered, and who is best placed to deliver it.1

I have spent 30 years as a corporate lawyer, working across major law firms and multinational corporations, including as General Counsel of two large public companies. In that time, I have watched the legal profession evolve – from the adoption of email and document management systems to the rise of sophisticated legal operations teams and the growth of Alternative Legal Service Providers (ALSPs).2 Yet nothing in those decades compares with the scale, speed, and impact of the transformation now underway.

The central argument is this: AI is reshaping competitive dynamics in the legal industry, and clients will be the primary force driving that change. AI is what economists call a “general purpose technology” – a breakthrough with broad applications that sparks complementary innovations across every sector of the economy.3 As this transformation unfolds inside companies, legal departments will evolve in parallel. Transformed clients will expect law firms to adapt in turn, delivering greater efficiency, innovation, and value, while integrating more closely with the client’s own operations.4

Negative inflection points are difficult for dominant industry players to spot.5 Many law firms are currently enjoying record profits, underpinned by long-standing competitive advantages and high barriers to entry. But those very same advantages can mask early signs of disruption and make it difficult to adapt or innovate.
