Where does the data come from?

The Legal Trends for Solo and Small Law Firms report uses a range of methodological approaches and data sources to deliver the best insights about the state of legal practice and strategies for future growth.

Clio data

We’ve analyzed aggregated and anonymized data from tens of thousands of legal professionals in the U.S. This data provides important insights about how technology is currently being used by legal professionals, as well as its impact on firm performance.

Survey of legal professionals

We surveyed 1,028 U.S. legal professionals from June 5 to 23, 2024. The legal professionals we surveyed included lawyers as well as support staff—such as paralegals and administrators—who are engaged in the management side of their practice. Additionally, we surveyed 1,437 Clio customers from April 15 to 25, 2024.

Survey of the general population 

We surveyed 1,003 adults in the U.S. general population from June 28 to July 2, 2024. This survey was designed to gauge attitudes, opinions, preferences, and behaviors regarding the legal profession among individuals who have hired lawyers in the past or who may become potential legal clients in the future. This sample is representative of the U.S. population by age, gender, region, income, and race/ethnicity based on the most recent U.S. census statistics.

Solo and small law firms are lagging in AI adoption—but that could soon change

In the 2024 Legal Trends for Solo and Small Law Firms report, we found that 19% of mid-sized and smaller law firms were using AI in their practice. 

While AI adoption has since surged across the legal industry, solo and small firms are apparently hesitant to integrate AI into their practices. Historically, smaller firms have been early adopters of legal technology, leading the way in cloud-based practice management software and online payments adoption. However, AI adoption has been much slower amongst them when compared to larger firms with many limiting their use or avoiding AI altogether. 

This hesitation could be due to resource constraints. For example, larger firms have the financial and technical infrastructure to adopt AI at a more advanced level. But, despite these challenges, solo and small firms recognize AI’s potential: more than four in five legal professionals believe AI use will increase over the next 12 months, suggesting that solo and small firms may simply be waiting to adopt AI. 

Among solo and small firms that have embraced AI, solo and small firms tend to prioritize tools that address their unique needs. For example, solo practitioners are more likely to use virtual receptionists, while small firms gravitate towards document drafting and automation tools. This targeted approach suggests that while solo and small firms aren’t adopting AI at scale, they may be leveraging it strategically to maximize efficiency and fill operational gaps. 

Must-know statistics on solo and small law firms’ AI use

• 72% of solo legal professionals and 67% of small firm legal professionals are using AI in some capacity in their practice. However, only 8% of solos and 4% of small firms have adopted AI widely or universally. 
  • Larger firms are significantly more likely to have adopted AI than smaller firms: 85% of larger firms are using AI in some capacity in their practice, while 35% have adopted AI widely or universally. 
• Among solo and small firms that have used AI, the most popular tools include generic non-legal AI tools (for example, ChatGPT) (57%/54%), legal research platforms (54%/56%), virtual receptionists (27%/16%), document drafting or automation tools (25%/30%), and eDiscovery solutions (20%/19%).
• Over four in five legal professionals in firms of all sizes believe that the usage of AI will increase in the next 12 months. 
• The top benefits of AI, according to solo and small firms, are saving time and increasing efficiency (61%/63%), saving money (37%/34%), and improving the quality of work (36%/34%). 

Solo and small firms are embracing flat fees, but the billable hour remains dominant

Solo and small law firms are increasingly incorporating flat fees into their billing practices. While hourly rates remain the most common method of billing, flat fees are gaining traction as clients demand more transparency and predictability in pricing. Solo firms are slightly more inclined to offer flat fees for entire cases, while small firms are slightly more inclined to apply them to specific tasks within a case. This reflects a broader trend toward offering flexible pricing options that cater to client preferences. 

Interestingly, despite the rising popularity of flat fees, larger firms are more likely to experiment with alternative billing models, like subscriptions, underscoring the growing importance of offering predictable, transparent pricing. As automation tools like AI reduce the time spent on routine tasks, the need for firms to adjust their billing models becomes increasingly critical. In fact, generative AI could put $27,000 in annual revenue per lawyer at risk if they stick to the traditional billable hour. 

For solo and small law firms, adopting flat fees alongside traditional billing models requires strategic planning. These firms must assess which services or tasks are best suited for flat fees and consider how AI could further streamline their operations and improve efficiency. As client expectations shift toward more predictable and transparent pricing, firms that effectively integrate flat fees into their business models will have a competitive edge. 

Key findings regarding firm billing models

• 75% of solos and 65% of small firms report using flat fee billing models, while 84% of solos and small firms report using hourly rates. 
• Among solo and small law firms offering flat fees as a payment option, 80% of solos and 72% of small firms used flat fees for the entire matter while 39% of solos and 43% of small firms used flat fees for specific activities within a matter. 

Referrals remain the strongest client acquisition tool for solo and small firms, but technology can enhance results

Both solo and small law firms agree: referrals are the top source of new client leads. And, while solo and small firms leverage various marketing channels—including websites, online reviews, social media, and SEO—referrals continue to deliver the highest return on investment. However, firms that strategically supplement referrals with a strong online presence and client intake technology are seeing even greater success. 

Many solo and small firms operate with limited marketing budgets, making it challenging to invest in multiple channels. As a result, they tend to focus on cost-effective strategies like word of mouth marketing and leveraging existing networks. Despite this, firms that incorporate technology into their client intake processes see tangible benefits, including higher revenues, increased client leads, and improved conversion rates. 

What to know about improved client intake performance

• 59% of solo and small firms report that referrals are their highest source of leads, while only 27% of larger firms report the same. 
• Revenue: we saw 53% higher revenue among solos and 28% higher revenue among small firms using e-signatures, online search ads, online schedulers, online intake forms, and text messaging. 
• Client leads: Solo firms enjoyed a 48% increase in client leads, while small firms experienced a 6% increase in client leads, using the same features. 
• Conversion rates: we saw improved conversion rates among solo and small firms using e-signatures (10%/10%), text messaging (7%/3%), and online intake forms (2%/5%). 
• Time to hire: we saw shortened hiring time among firms using online search ads (26%/31%), e-signatures (23%/24%), online schedulers (10%/7%), and online intake forms (9%/5%). 

Solo and small firms lead the way in cloud-based practice management software adoption, but solo firms are investing less in software

For both solo and small law firms, salaries (for both partners and staff) make up over one-third of their total expenses. However, solos spend a significantly larger proportion of their total expenses on partner salaries, while small firms spend a significantly larger proportion of their total expenses on staff salaries. 

Investments in software and professional fees are the highest law firm spending growth areas, suggesting that firms are focusing their attention on these areas. The average law firm spends just under 2% of its overall expenses on software (slightly more than the U.S. Census’s industry estimate), aligning with the spending habits of small firms. However, solos are spending half of that amount and have the lowest software spending of the cohorts we reviewed. 

For both solo and small law firms, the most popular tools include cloud-based data storage, video conferencing, e-signatures, electronic filing, online and electronic payments, and cloud-based practice management software. Furthermore, solo and small law firms are significantly more likely to use cloud-based legal practice management software and online or electronic payments tools compared to larger firms.

Our findings on mid-sized firm spending and adoption habits

• The top expenses among solo and small firms are partner salaries (19%/6%), staff salaries (18%/30%), office expenses (11%/6%), marketing (9%/5%), and rent (7%/7%).  
• The average small law firm spends 2% of its expenses on software—or the average U.S. Census industry estimate. However, the average solo firm spends only half the U.S. Census industry estimate on software.
• The most popular technology among solo and small firms include cloud-based data storage tools (81%/85%), video conferencing (80%/80%), cloud-based practice management software (79%/81%), online or electronic payment tools (76%/72%), and e-signature tools (72%/78%). 
• 79% of solos and 81% of small firms use cloud-based legal practice management software, compared to only 47% of larger firms. 

The final word on the 2025 Legal Trends for Solo and Small Law Firms report

Despite slower initial adoption, the future of AI in solo and small law firms looks promising. These firms are clearly aware of AI’s transformative potential, especially when it comes to increasing efficiency, saving time, and improving the quality of their work. While they may not yet be adopting AI at the same scale as larger firms, the data suggests that many are taking a strategic, needs-based approach—investing in tools like virtual receptionists, legal research platforms, and document automation that deliver the greatest operational impact. As these tools become more accessible and user-friendly, we can expect to see a broader wave of AI adoption among solo and small law firms. 

At the same time, solo and small firms are continuing to adapt in other important ways, from embracing flat fees to streamlining client intake through technology. These changes not only improve the client experience but also help firms remain competitive in a rapidly evolving legal landscape. By investing in the right technologies—AI included—and aligning pricing and intake models with client expectations, solo and small firms can continue to punch above their weight, offering personalized service with the efficiency and agility of larger operations. The firms that succeed will be those that view technology not as a burden, but as a critical partner in delivering better legal services.
