In the previous episode, we looked at the timesheet as a data problem: an often reconstructed number that firms use to make serious decisions. Behind that problem sits a bigger question. What happens when an entire business model is built around selling that number?
When time becomes the commercial unit, the firm builds everything around time. More hours mean more revenue. Longer matters look attractive. Efficiency becomes awkward, because the model rewards effort sold more generously than friction removed. Firms have good reasons for working this way: the hour is legible to clients, flexible for partners and clear for associates, and nobody has to agree in advance on the value of the outcome. That logic held for decades, especially in Big Law. It is now starting to crack.
The incentive problem
Think about what a general counsel actually wants when the phone rings at seven in the evening. Sometimes the move from risk to confidence takes hundreds of hours. Sometimes it takes one call with the right lawyer who has seen the problem before. The billable model struggles with both extremes. When work runs long, the client carries the risk. When expertise or technology makes it fast, the firm earns less precisely because it performed better. The model rewards duration over resolution.
Clients know this, even as they keep accepting hourly billing. So both sides behave defensively. Firms write narratives to justify time. Clients challenge invoices. Partners discount to preserve relationships. Procurement imposes caps, e-billing rules and matter budgets. The relationship drifts from value towards leakage control, a trust problem expressed through billing mechanics.
The same tension lives inside the firm. Associates learn to measure their own worth, and their future bonuses, in recorded hours, and many carry that habit for the rest of their careers. The firm says it wants efficiency, while the model often monetises inefficiency better than redesign. If a new tool removes fifty hours from a matter, who benefits: the client, the firm or the associate? Until the commercial model changes, automation keeps raising questions that hourly billing was never built to answer.
One model, many markets
An honest caveat: there is no single billable model. Pricing varies enormously by country, client base and professional rules. A Wall Street litigation boutique, a Milan corporate firm and an alternative legal services provider in London live in different commercial worlds. Bar rules differ too. Some jurisdictions restrict success-based fees, others have built entire litigation markets around contingency arrangements, and fee scales still shape pricing in parts of continental Europe. A private equity fund, a public administration and a family business each buy legal services in their own way.
The hour was never universal in any case. Plenty of firms already work without it. Criminal and family lawyers quote flat fees, boutiques work on fixed or capped arrangements, and providers sell subscriptions. Firms advising private equity are used to share in the upside of the deals they enable. A US trial litigation firm can take a part of the outcome through a contingency fee. Others keep the timesheet purely as an internal instrument, a way to understand cost and capacity, while selling the client something else entirely. None of this is theoretical. These alternatives already exist, tested daily.
The pricing architecture firms need
AI makes the question urgent. If a task that once took a junior two days can be done in twenty minutes, charging as though nothing changed becomes hard to defend. That does not mean every matter should become a fixed fee, because some work is genuinely uncertain and still fits hourly billing. The problem is the default. What replaces it is a pricing architecture, assembled from several models that each fit a type of work.
Some examples of alternative arrangements:
- Repeatable work can be priced differently from tailored advisory work.
- High-volume work can be bundled or sold by subscription.
- Strategic advice can be priced around access, priority or judgement.
- Transactional work can combine a fixed component with a success fee tied to closing, a structure M&A clients already know from their bankers, where the rules allow it and the risk is priced consciously.
- Some matters can stay hourly, with better budgets and explicit rules on scope change.
All of this asks firms to know their own economics far better than most currently do: reliable matter data, task-level understanding, delivery discipline. Lacking that foundation, “alternative fee arrangements” become theatre, hourly economics hidden under a different label. In our experience, this is where most pricing projects quietly die, in the gap between the ambition of the fee structure and the quality of the data underneath it.
Taken seriously, pricing is a theory of the firm. It tells clients what the firm believes its value is, partners what work the firm wants, associates what behaviour earns reward, and management whether the firm is selling labour, access, judgement, certainty or risk transfer. Behind the billing format sits the operating logic of the whole firm.
From theory to action
The billable model will not collapse overnight. It is too embedded and too familiar. But its role will narrow. The firms that understand this early will build a deliberate pricing system: hours where hours make sense, repeatability priced differently from uncertainty, risk shared where rules and economics allow, and AI used to change delivery rather than merely cut cost.
Firms that miss the shift will find others making it for them. Clients will do the segmentation. Procurement will decide what is premium and what is commodity. AI-enabled competitors will take the repeatable work.
A firm can keep excellent lawyers and still lose control of the economics of their work. The real test is whether it can explain, with evidence, why a given pricing model fits a given type of work, in its market, for its clients, under its rules. Where the only answer is “this is how we have always billed”, the model is already weaker than it looks.
