TLDR
For a solo attorney in 2026, the right practice management software depends on one question: is IOLTA trust accounting included in the base plan? CosmoLex ($119/user/month) is the deepest trust accounting option but priced for firms. CaelusLaw ($20/user/month, Essentials) includes IOLTA at every tier and is built specifically for solo practitioners. Clio ($39+/user/month) is the market leader but fragments trust accounting into higher-tier plans. MyCase ($39/user/month) is the lowest entry point if you do not yet hold client funds.
| Tool | Pricing | Verdict |
|---|---|---|
| CaelusLaw | $20-39/user/mo | Best for solo attorneys who want IOLTA compliance built in from day one at a price that makes sense for a one-person practice. |
| Clio | $39-149/user/mo | Best for solo attorneys who need integrations with other tools and can absorb the higher cost of unlocking trust accounting features. |
| PracticePanther | $49-89+/user/mo | Reasonable mid-tier option if you already use QuickBooks for accounting and only need trust accounting basics. |
| MyCase | $39-99/user/mo | Best for solo attorneys in the early stage who prioritize client communication and do not yet hold significant client funds. |
| CosmoLex | $119-149+/user/mo | Best if IOLTA compliance is the top priority and your practice generates enough revenue to justify $119+/month. Overkill for a new solo. |

See plans & pricingHow We Evaluated
We looked at these tools through the lens of a solo attorney making the software decision alone, without an IT department, bookkeeper, or dedicated administrator. The criteria:
- IOLTA trust accounting in the base plan — the single most important compliance requirement for any practice that holds client funds
- Time to operational — how fast can a solo get from signup to billing a client?
- Price at the tier you actually need — not the lowest advertised price, but the plan that includes trust accounting
- Contract terms — month-to-month flexibility matters for a solo practice
All pricing is as of March 2026.
1. CaelusLaw
CaelusLaw is built for solo and small-firm attorneys from the ground up. The Essentials plan at $20/user/month includes IOLTA trust accounting, matter management, time tracking, and billing in one tool with no separate accounting subscription required.
The setup process is designed to be completed in an afternoon: create matters, import contacts, configure your trust account, and start tracking time. There is no onboarding call required to get the basics operational.
Pros
- IOLTA trust accounting with three-way reconciliation in the base plan
- No annual contract or setup fees
- Built for solo setup, not adapted from a multi-firm product
Cons
- Newer product with fewer integrations than established competitors
- Feature depth in areas like document assembly still expanding
Pricing
$20/user/month (Essentials), $39/user/month (Complete). No contract required.
Verdict
For a solo attorney who wants IOLTA compliance from day one at a price that fits a one-person practice, CaelusLaw is the right starting point. Start your free trial.
2. Clio
Clio is the most widely used practice management platform in the market. Its integration library, feature depth, and established reputation make it a reasonable default for many attorneys. For solo practitioners, the primary complication is that trust accounting is not included in the EasyStart or base plans.
Pros
- Largest integration ecosystem (200+ third-party apps)
- Strong document management and client portal
- Large user community and extensive documentation
Cons
- Trust accounting requires Essentials ($69/user/month) or higher
- The Clio product suite (Manage, Grow, Draft) are sold separately, adding cost
- User reports of frequent price increases and sales misrepresentation
Pricing
$39/user/month (EasyStart), $69/user/month (Essentials), $99/user/month (Advanced), $149/user/month (Complete). Trust accounting starts at Essentials.
Verdict
Clio is a defensible choice for a solo who values integrations and has the budget for the Essentials tier or above. The EasyStart plan excludes trust accounting, which is the wrong setup for any solo who will hold client funds.
3. PracticePanther
PracticePanther positions itself as a simpler, more affordable alternative to Clio. For solo attorneys, the main limitation is that trust accounting requires the Business tier.
Pros
- Clean interface that most attorneys pick up quickly
- Competitive pricing at the Solo and Essential tiers
- Good client intake and portal features
Cons
- Trust accounting only available at Business tier ($89+/user/month)
- Mobile app has significantly fewer features than the desktop version
- Payment processing speed has been a consistent complaint
Pricing
$49/user/month (Solo), $69/user/month (Essential), $89+/user/month (Business). Trust accounting requires Business tier.
Verdict
PracticePanther is a reasonable choice if you are already using QuickBooks and want a practice management layer on top. The trust accounting limitation at lower tiers is the same problem as Clio — a solo who holds client funds needs to budget for the Business tier.
4. MyCase
MyCase focuses on client communication: portal access, messaging, document sharing. It is the most affordable starting point for solo attorneys who want to move off spreadsheets without a large monthly commitment.
Pros
- Lowest advertised entry price at $39/user/month
- Built-in client portal with messaging and document sharing
- Simple, clean interface that is easy to navigate
Cons
- Trust accounting only available in Pro tier ($79/user/month)
- Invoice customization is limited — problematic for attorneys with complex billing arrangements
- Handling clients with multiple active matters is reported as awkward
Pricing
$39/user/month (Basic), $79/user/month (Pro), $99/user/month (Advanced). Trust accounting requires Pro tier.
Verdict
MyCase Basic makes sense for a solo attorney in the very early stage who does not yet hold client funds and wants the most affordable practice management tool. Once your practice holds retainers, upgrading to Pro for trust accounting effectively doubles the cost.
5. CosmoLex
CosmoLex is an accounting platform first, with legal practice management built on top. Its trust accounting is the most comprehensive in the market. The tradeoff is price and complexity.
Pros
- Fully native legal accounting and IOLTA trust accounting at every tier
- Eliminates the need for a separate QuickBooks subscription
- Three-way reconciliation is automatic, not manual
Cons
- $119/user/month is higher than most solo attorney budgets for year-one practices
- Learning curve is steep — attorneys without accounting backgrounds report a difficult initial setup
- Interface is older and less polished than newer tools
Pricing
$119/user/month (Standard), $149+/user/month (CosmoLex+). All tiers include full trust accounting.
Verdict
CosmoLex is the right tool if you are a solo attorney running a practice with significant trust account volume and you want to eliminate a separate accounting subscription. At $119/month minimum, it is not the first tool most new solos should start with.
Q&A
What is the best legal practice management software for solo attorneys?
For solo attorneys in 2026, the best tool is one that includes IOLTA trust accounting in the base plan and can be operational in a day. CaelusLaw ($20/user/month, Essentials) is built specifically for solo and small-firm attorneys with IOLTA included. CosmoLex has the deepest trust accounting but at $119/user/month it is priced above most solo budgets. Clio is the widest-used option but requires mid-tier plans to unlock trust accounting.
Q&A
Does legal practice management software for solo attorneys include trust accounting?
It depends on the tool and plan. CaelusLaw includes IOLTA trust accounting at every tier. CosmoLex includes it at all plans. Clio requires the Essentials tier or higher. PracticePanther and MyCase lock trust accounting behind Business-level plans. For a solo attorney who holds any client funds, a tool that includes trust accounting in the base plan avoids the upgrade trap.
Q&A
How do I switch practice management software as a solo attorney?
The cleanest migration happens when you move at the start of a new billing period with few outstanding trust balances. Most vendors offer data export in CSV format for contacts and matters. Trust account records require more care: you need to reconcile your final trust balance before migration and set up opening balances in the new system. Ask the new vendor specifically what migrates automatically and what requires manual re-entry.
No credit card required. No annual contract.
