The end of the hourly rate: how AI accelerates the transition to fixed fees

“You cannot combine the time savings of AI with a business model based on time loss.”

The classic hourly rate, for years the foundation of the legal profession, is faltering. Due to the rise of artificial intelligence (AI), the hourly rate business model is coming under increasing pressure. According to Jack Newton, founder of Clio, one of the leading Legaltech companies in North America, the hourly rate is simply unsustainable in a world where AI handles the majority of legal work in minutes. This is evident from various studies conducted by Clio in recent months.

Yet today, more than 80% of law firm revenue comes from work based on an hourly rate. Does a change in this business model not involve significant losses within the legal profession? On the contrary: AI offers new opportunities. Firms that embrace AI and switch to fixed fees or hybrid models can expand their reach, work faster, and become more profitable.

This is what AI is already doing to the business model according to Clio (US/Canada)

• Up to 74% of work currently billed by the hour can be technically automated.
• Firms that deploy AI broadly are more likely to switch to fixed fees instead of hourly rates.
• Clients overwhelmingly prefer predictable costs: 51% prefer fixed fees or subscription models.
• Fixed-fee cases are completed on average 2.6 times faster, paid nearly twice as fast, and invoiced five times faster than hourly rate cases.
• Between 2016 and 2024, the total value of fixed-fee cases rose by 51% (adjusted for inflation).

What did Clio investigate?

Clio analyzed over 7 million time entries from lawyers, paralegals, and support staff in the United States and Canada, sourced from users of their own platform. This data is linked to the AI categories of research by Goldman Sachs and provides a realistic picture of the extent to which legal work can be automated.

The analysis shows that:

• 57% of hours worked by lawyers can be automated.
• 69% of hours worked by paralegals can be automated.

According to Clio, these are not theoretical estimates, but hard data. And the percentages will increase.

Why the hourly rate is becoming unsustainable

AI is taking over routine tasks: from case analysis to drafting pleadings. Where you used to work five hours on a case, five minutes will soon suffice. But five minutes is not billable as five hours, even if the value to the client remains the same. This exposes a fundamental tension: the hourly rate rewards inefficiency. The legal sector is one of the few professions that explicitly charges for time, regardless of the result. But AI is changing that. Clients do not want time; they want outcomes. And they are willing to pay for them, as long as the price is clear upfront.

Case studies: how firms are changing their approach

• According to Clio’s analysis, 20% of firms working with fixed fees adopt AI “broadly or universally,” compared to only 7% of firms that work primarily with hourly rates. The exact names of these firms are not mentioned, but the data is anonymized from thousands of small and medium-sized North American firms using Clio’s platform.
• Fixed-fee cases are completed on average 2.6 times faster.
• Payments for fixed fees are received nearly twice as fast.
• Client conversion increases by 20% when using technology for intake, scheduling, and e-signatures.

What should your firm do now?

According to Clio, CEO Jack Newton, and Clio’s legal advisor Joshua Lenon, there are five immediate steps firms can take now:

1. Move away from the hourly rate as the default. Focus on outcome and value, not on minutes worked.
2. Offer fixed fees wherever possible. Consider predictable tasks such as contracts, incorporations, and standard procedures.
3. Use hybrid models for more complex cases. Combine a fixed price for routine tasks with an hourly rate for the unpredictable portion.
4. Invest in AI tools and skills training. Ensure that employees can use AI efficiently and understand its application.
5. Redesign your service delivery. Focus on accessibility, speed, and clarity—exactly what clients value.

Conclusion

AI is forcing the legal profession to rethink its business model. Not because it has to, but because it pays off. The classic hourly rate loses its value in a world where speed, transparency, and results are paramount. Firms that switch to fixed fees and hybrid models now are building a more efficient, accessible, and profitable practice. The question is not if the hourly rate will disappear, but when you decide to move with the change.
