Quick read.
- Solo firms bill 26% vs. 45% utilization at large firms.
- Solo attorneys charge a lower hourly rate on average ($288 vs. $345).
- There’s a $637/day revenue gap per attorney ($155k+ annually).
- Outsourcing call handling, intake and scheduling can help increase billable hours.
Launching your own solo or small firm is liberating — but it also puts you at a distinct revenue disadvantage compared to larger firms. Recent data highlights just how wide this billing gap has grown — and why it’s critical to address it.
Solo firms bill significantly less than larger ones.
Clio’s 2024 Legal Trends report shows that attorneys bill roughly 2.9 hours per 8-hour day (only 37% utilization).
However, other research by Clio shows that:
- Larger firms enjoy higher average utilization rates
- The utilization rate for firms with 20 or more employees is almost double solo firms (26% vs. 45%)
- Solo practitioners earn significantly less per hour than larger firms ($288 vs. $345)
Wondering what this means in real terms? Let’s run the numbers.
Professional. | Utilization. | Hourly rate. | Billable hours per 8‑hour day. | Daily revenue. |
---|---|---|---|---|
Solo lawyer | 26% | $288/hour | 2.1 hours | $605 |
Large‑firm lawyer | 45% | $345/hour | 3.6 hours | $1,242 |
That’s a revenue difference of $637 per day, or roughly $155,000 annually, before accounting for realization, uplift in collection or alternative pricing approaches.
The big-firm advantage is growing.
Large law firms continue to raise rates: LexisNexis reported a 5.1% increase in average partner fees in 2024, with top-tier partners commanding rates over $2,300/hour. Reuters says rates are even hitting $3,000/hour for superstar attorneys.
Despite solo and small firms increasing both billable rates and hours since 2016, large firms still outperform them significantly in total revenue and billing efficiency.
How solo practitioners can close the gap.
The solo attorney faces big challenges in lost revenue on a daily basis.
Some of the reasons? There is little to no help with non-billable functions. Time management is magnified when the individual lawyer has to handle client needs, answer her own phone, manage the hours billed and collect payments.
The lawyers who make up solo and two-person firms find great rewards in working for themselves, but these numbers reflect the high need to inject efficiency into the day through office management support.
These are some of the ways to close the gap:
- Improve utilization: Aim to reclaim admin time by outsourcing phone coverage, intake, and scheduling — every additional 10% in utilization can add tens of thousands of dollars in revenue each year.
- Enhance realization & collection: Online payments, automated reminders, and efficient billing tools can reduce lockup and unbilled work.
- Rethink rate models: Some solo firms now offer flat or hybrid fees — Clio reports that 75% of solos use some flat-fee billing, increasing predictability and client satisfaction.
- Adopt tech and virtual reception: Using tools like virtual receptionists ensures no client call or lead slips through — driving more billable work and referrals.
