This is the first in a short series of blog posts in which I’ll explore not just the challenges, but also the opportunities and emerging solutions, presented by generative AI for the pricing of legal services.
Pricing Legal Services in the Era of AI: The Problem
Let’s start with an uncomfortable truth.
For decades, law firms have priced largely by reference to time. It’s simple, familiar and – until recently – defensible. But the arrival of generative AI is beginning to expose just how fragile that model really is.
AI is not just another efficiency tool. It is fundamentally altering the production of legal work. Tasks that once absorbed hours of valuable fee earner time—research, first drafts, document review—can now be completed in minutes.
And that creates a problem. Not a theoretical one. A live, commercial tension that Thomson Reuters have called an ‘almost absurd tension’. What took 10 hours might now take 2. You can’t charge for 10 hours, obviously, but charging for just 2 would be ‘almost absurd’.
Clients can see it.
They may not understand exactly how the technology works, but they understand enough to ask the obvious question: why does this still cost what it used to? The historic link between time spent and price charged is starting to look increasingly difficult to justify.
At the same time, firms are experiencing internal pressure. Fewer hours recorded means pressure on utilisation, on realisation, and ultimately on profitability—at least if nothing else changes.
Layer onto this a further complication: inconsistency. Some teams and individuals are embracing AI quickly; others are not. The same piece of work can now be delivered in radically different ways, at radically different internal costs, but too often priced in exactly the same way. That disconnect is becoming harder to manage—and harder to explain.
And perhaps the most challenging issue of all: uncertainty about value. No one quite knows where the market will settle, but everyone senses that the ground is shifting beneath them.
If time is no longer a reliable proxy, what is? Firms know, instinctively, that their worth does not lie in how long something takes. But articulating that—consistently, credibly, and commercially—is proving difficult.
So here is where we are.
Costs of production falling.
Client scrutiny rising.
Traditional pricing models under strain. And no clear consensus across the market as to what replaces them.
In the next of my blog posts, I’ll look more closely at value pricing and the models likely to displace the billable hour.
