Legal billing software for solo attorneys: how to pick the right tool without paying for features you don't need
Solo attorneys face a market built for law firms. Every legal billing platform — Clio, MyCase, Smokeball, TimeSolv, Bill4Time — bundles time capture, invoice generation, trust accounting, document storage, and client portal access into a single subscription priced at $39–$159/user/month. A solo who needs only two of those five jobs pays for all five. The right question is not "which legal billing software should I use?" It is "which jobs do I actually need done, and what is the cheapest stack that covers them?"
TL;DR
There are three distinct legal billing jobs: (1) time capture — recording billable events as they happen; (2) billing presentation — turning time entries into invoices; (3) payment processing — collecting from clients with trust-account awareness. Most PMS products bundle all three plus case management at $79–$159/mo. A solo who needs only the first two can use ClaimHour ($29–$59/mo) + QuickBooks Essentials ($65/mo) for $94–$124/mo total, keeping Clio-level capture quality without Clio's overhead. The unbundled path is the right default for the 120,000 US solos billing from QuickBooks without a PMS.
The three legal billing jobs (and why they are usually sold as one)
Job 1: Time capture
Time capture is the most revenue-critical job and the hardest to do well. Every hour a solo spends on a client matter needs to make it onto an invoice — the phone call in the car, the quick email draft before coffee, the document review during a late-night session. Manual timers (the "start/stop" button in Clio or MyCase) require the attorney to remember to start and stop the timer. The Clio Legal Trends Report finds that attorneys who track time manually capture 1.9 hours per day on average — versus the 2.5 hours per day they actually work on client matters. That 0.6-hour gap, at $250/hr, is $150/day × 240 working days = $36,000/year of leakage.
Passive capture — software that automatically records events as they happen without requiring a timer interaction — closes that gap at the source. ClaimHour's metadata-only passive capture (call duration, email-compose time, document-edit focus-duration, calendar events) provides the capture layer without reading call audio, email bodies, or document contents, which keeps attorney-client privilege intact.
Job 2: Billing presentation
Billing presentation is turning time entries into an invoice the client can read and pay. This is a solved problem. QuickBooks Online Essentials ($65/mo) does it. FreshBooks ($30/mo) does it. Both support itemized line items with date, description, hours, and rate — the four fields in a legal billing invoice. Neither is optimized for legal billing specifically (trust accounting, UTBMS codes, retainer management), but for a solo who invoices from an operating account and uses LawPay for client payments, QuickBooks or FreshBooks covers the billing-presentation job at a fraction of PMS cost.
Job 3: Payment processing with trust-account awareness
Trust accounting — IOLTA compliance, three-way reconciliation, retainer draw-down tracking — is the most legally sensitive job in the billing stack. Bar disciplinary records show that trust accounting errors are among the top three causes of attorney discipline in most states. LawPay Standard (free to $20/mo with bar-association sponsorship) is the trust-aware payment processor most solo attorneys use. It routes interchange fees from operating, never from trust — the distinction that keeps Stripe-on-trust users out of bar grievance proceedings. LawPay Standard handles the payment processing and trust reconciliation job.
Legal billing software comparison for solo attorneys (2026)
| Product | Price / user / mo | Passive capture | Invoicing | Trust accounting | Best for |
|---|---|---|---|---|---|
| ClaimHour Pro | $59 | Yes (metadata-only) | Export to QB/LawPay/CSV | Via LawPay | Capture-first no-PMS solos on Mac |
| Clio Manage Essentials | $49 | Manual timer | Yes | Yes | Solos who need PMS features |
| Clio Complete (with Clio Duo) | $159 | AI-drafted narratives (reads content) | Yes | Yes | Firms wanting AI-driven billing narratives |
| MyCase Pro | $79 | Manual timer | Yes | Yes | Solos who need client portal |
| Smokeball (AutoTime) | $49+ | Yes (Windows-only agent) | Yes | Yes | Windows-based solos in firm context |
| TimeSolv | $35 per timekeeper | Manual timer | Yes | Yes (add-on) | Solos wanting standalone billing without full PMS |
| Toggl Track | $10–$20 | Manual timer | No (export only) | No | Non-legal freelancers; usable by solos who invoice separately |
The key column is "passive capture." Every PMS except Smokeball uses a manual timer — which means the capture gap remains open regardless of invoice quality. Smokeball AutoTime is Windows-only and requires a Smokeball PMS subscription at $49+/mo. ClaimHour is the only Mac-native passive-capture tool without a PMS requirement.
The unbundled stack: what it costs and when it makes sense
For a solo billing $250/hr out of QuickBooks without an active PMS, the unbundled stack has three components:
- ClaimHour Pro ($59/mo) — passive capture of calls, emails, documents, calendar events; 0.1-hour rounding; daily digest; QuickBooks IIF + LawPay + FreshBooks + CSV export
- QuickBooks Online Essentials ($65/mo) — invoicing, operating-account bookkeeping, client billing history
- LawPay Standard ($0–$20/mo) — client payments, IOLTA trust accounting, bar-association pricing
Total: $124–$144/mo versus Clio Complete at $159/mo or MyCase Pro at $79/mo (with a manual timer that leaves the capture gap open).
The unbundled stack is the right choice when: you are already billing from QuickBooks, you do not actively use a client portal, you do not need court-date docketing in your billing system, and your primary billing problem is capture (not invoice format). If you need a full PMS — client portal actively used, integrated calendaring, document storage — a PMS is the right choice. The question to ask is not "is ClaimHour cheaper than Clio?" but "which Clio jobs am I actually using, and am I paying for five jobs to get one?"
How ClaimHour fits the legal billing decision
If you are a solo billing hourly from QuickBooks without a PMS — and your primary unsolved problem is the capture gap (the 0.6 hours/day of billable work that doesn't make it onto an invoice) — ClaimHour is the capture layer in a three-component unbundled stack.

Related questions
What is the difference between a time capture tool and a legal billing platform?
A time capture tool records billable events as they happen. A legal billing platform turns time entries into invoices. Practice management systems bundle both plus case management, trust accounting, and client portal. A solo who only needs capture + invoicing can unbundle: ClaimHour ($29–$59/mo) for capture + QuickBooks ($65/mo) for invoicing = $94–$124/mo versus $79–$159/mo for a full PMS.
Do I need a practice management system as a solo attorney?
It depends on which jobs you need: client portal, integrated court-date calendaring, trust accounting in one place, document storage, and conflict checking all point toward a PMS. If you are billing from QuickBooks and your workflow is call → draft → invoice → collect via LawPay, a PMS adds complexity without solving your primary problem. About 30% of US solos bill without a PMS by choice; for them, an unbundled stack (ClaimHour + QuickBooks + LawPay) covers all three billing jobs at lower total cost.
How does bar-standard 0.1-hour rounding work in legal billing software?
Most state bar ethics guidance treats 0.1-hour (6-minute) intervals as the standard billing unit. ClaimHour Pro applies 0.1-hour rounding to all captured events automatically. A 23-minute call appears as 0.4 hours in the digest; a 7-minute email session appears as 0.2 hours. The exported time entry is already formatted for your invoice without manual rounding.
What legal billing software works without a Mac?
ClaimHour is Mac-first (macOS menubar + iOS companion) and uses macOS native APIs not available on Windows. For Windows-based solos, PMS-bundled timers (Clio, MyCase, Smokeball on Windows), or standalone timers (Toggl, Harvest), are the available options. A Windows passive-capture tool with ClaimHour's metadata-only privacy posture does not currently exist at the sub-$100/mo solo price point.
