AI and the Billable Hour: Should Law Firm Pricing Change?

THE CONFLICT

The Billable Hour Has a Built-In Conflict

Law firms have spent decades selling time. Then we bought technology designed to save it. That creates a problem. If a lawyer takes two weeks to complete a project, the client waits and the firm gets paid. If better systems help the lawyer finish the same work in two days, the client receives more value, but the firm may earn less.

That is a strange incentive for any business. It’s especially hard to defend as AI becomes part of daily legal work.

In a recent episode of The War Room: Disrupted, I discussed this tension with Andrew Legrand, founder of Spera Law Group, LLC. Andrew has spent years building subscription legal services for businesses. He put the issue plainly:

“I really don’t understand how businesses are going to continue to pay lawyers by the hour when AI is a thing.”

I agree. AI may also help reduce the cost of legal work by organizing information, reviewing documents, preparing drafts, and spotting patterns faster. Lawyers must still check the work, apply judgment, protect client information, and take responsibility for the final product. But fewer hours may be needed to reach the same or better result.

If the only thing a firm sells is time, every hour saved starts to look like lost revenue. That conflict is one reason the traditional law firm model is coming under greater pressure.

VALUE OVER HOURS

Clients Are Buying More Than Time

Clients don’t come to a lawyer because they want ten hours of legal work. They want an agreement reviewed, a problem prevented, a business protected, or a family matter resolved. They are buying judgment and an outcome.

I once met with a family law client and spotted an issue within minutes that was worth about $1.7 million to her. Under a strict hourly model, the bill for those few minutes would have been almost nothing. But the value of the advice was enormous.

But that doesn’t mean I should have charged her $1.7 million. It means time alone is a poor measure of legal judgment.

Experience often allows a lawyer to recognize an issue faster. Technology can make that lawyer faster still. Neither should make the advice less valuable simply because it took less time to deliver.

NEW INCENTIVES

Subscription Pricing Changes the Incentive

Andrew explained that subscriptions now produce about 70% of his firm’s revenue. His clients pay a set monthly amount for ongoing access and support, with certain work priced separately. The firm reviews each subscription twice a year and adjusts the price when the client’s needs change.

As Andrew said:

“The clients aren’t necessarily paying for our time. They’re paying for our responsiveness and our processes.”

Under that model, the firm has a reason to answer quickly, build better systems, and catch concerns before they become expensive disputes. The goal is to remain useful enough that the client continues the relationship.

That turns the lawyer into something closer to a business partner. During our conversation, I told Andrew, “You almost become more of a partner in the business that way.” The lawyer learns how the company operates, notices risks the owner may not recognize, and can help address them earlier.

This is where subscriptions and AI can work well together. Knowledge gained from one problem can help identify similar risks for other clients. The firm becomes faster and more proactive, while clients receive ongoing value and predictable legal costs.

ETHICS & PRICING

Rule 1.5 Should Protect Clients, Not Freeze the Market

Lawyers can’t simply invent a new price and call it innovation. Fees must be reasonable, the scope of the work must be explained, and clients need to know what they are agreeing to.

ABA Model Rule 1.5 lists several factors for deciding whether a fee is reasonable. Time and labor are among them, but not the only ones. The rule also considers difficulty, customary fees, results, time limits, experience, the professional relationship, and whether the fee is fixed or contingent. State rules and their application vary.

The ABA’s Formal Opinion 512 also makes an important point. A lawyer using generative AI may charge for the time spent using the tool and reviewing its output but can’t bill for hours that were not actually worked just because the task once took longer. That protection makes sense. Clients shouldn’t be billed for imaginary time.

The harder question is whether a reasonable fixed or value-based price should be judged mainly by how long the lawyer took. In some courts and practice areas, that remains a real concern. A fee may be agreed to in advance and fully explained, yet later be viewed through the old lens of hours multiplied by rate.

When that happens, firms have less reason to offer new pricing models. The rule meant to protect clients can create friction for the very changes that could make legal costs more predictable.

THE RIGHT FIT

Not Every Legal Matter Fits One Model

The billable hour is not going to disappear tomorrow, and it shouldn’t be replaced with a black box.

Some legal matters are difficult to price at the beginning. Litigation can change quickly, new information can expand the work, and subscriptions need firm boundaries so one monthly price does not become unlimited representation. The better answer is choice.

A firm might use subscriptions for ongoing advice, fixed prices for defined projects, hourly billing for uncertain litigation, and separate pricing when the scope changes. Clients should understand what’s included, how the price may change, and what happens if the relationship ends.

This isn’t about finding a clever way to charge more. It’s about removing unnecessary friction between the lawyer and the client.

CATCHING UP

Law Firm Pricing Has to Catch Up

The legal industry is already questioning the future of hourly billing. In the 2026 Future Ready Lawyer Survey, 62% of legal department respondents said AI-driven time-savings will significantly reduce the use of the billable hour.

That change requires more than technology. Firms must rethink what they sell, clients must compare new models, and regulators must make room for new legal business models while continuing to protect the public.

The firms that get this right will not simply complete the same work faster. They’ll build services around responsiveness, prevention, access, and the value of good judgment.

AI is forcing the legal industry to answer a question it has avoided for a long time: If a lawyer can solve the problem faster, should that make the work less valuable?

I don’t believe it should. But I also don’t believe clients should pay for time that was never spent.

The future of law firm pricing sits between those two ideas. Our job now is to build models that are fair to the client, sustainable for the firm, and honest about what legal help is really worth.
