Going Solo as an Attorney: The Business Infrastructure Checklist for Lawyers Launching Their Own Practice

You've made the decision. After years — maybe decades — in big law, government, or a mid-size firm, you're going solo. No more billable hour quotas dictated by someone else's business model. No more partnership politics. No more clients you didn't choose.

But the freedom of solo practice comes with a truth nobody warns you about: you are now the CEO, CFO, COO, CTO, and head of HR. You are also the attorney. And every minute you spend figuring out whether to form an LLC or PLLC is a minute you're not billing.

The attorneys who thrive in solo practice aren't necessarily the best lawyers in the room. They're the ones who built the operational infrastructure before they needed it. Here's the complete checklist for lawyers hanging their own shingle — covering everything from entity formation to the marketing engine that keeps the pipeline full.

Entity Formation and Compliance

Before you sign your first client, your businessentity needs to exist and be properly licensed. Be compliant with yourstate's rules for law practice ownership.

Choose Your Entity Structure

Solo Practice PLLC (Professional Limited Liability Company) — The most common structure for solo attorneys. Provides liability protection for business debts (though not malpractice liability — that's what malpractice insurance is for). Pass-through taxation avoids corporate double taxation. Most states require PLLCs for licensed professionals.

Solo Practice PC (Professional Corporation) — Similar liability and tax treatment to PLLC but with more formal governance requirements (bylaws, board meetings, shareholder records). Some attorneys prefer PCs if they plan to add partners later. PCs can elect S-corp status for tax advantages.

Solo Practice LLC (non-professional) — Generally not available for law practice in states with unauthorized practice of law restrictions. Check your state specifically; some allow it with proper licensing disclosures.

Sole Proprietorship — Don't do this. Zero liability protection. Zero tax advantages. No reason to operate as a sole proprietorship when PLLC formation costs $500-$1,500 in most states.

Recommendation: Start with a PLLC unless you have specific reasons to prefer a PC. It's simpler, cheaper, and provides the same core protections.

Formation Checklist

Reserve and register your business name with the state. File Articles of Organization or Articles of Incorporation. Draft Operating Agreement or Bylaws. Obtain EIN from IRS. Register with state tax authority. Obtain business bank account (separate from personal — non-negotiable). Register for state and local business licenses. File Statement of Information (annual requirement in most states). If required, publish notice of formation in local newspaper (California, Arizona, Nebraska, New York).

IOLTA and Trust Account Setup

If you handle client funds — retainers, settlements, third-party payments — you need an Interest on Lawyers Trust Account (IOLTA) or equivalent trust account.

Open IOLTA at a bank approved by your state bar. Understand the difference between trust account and operating account — never commingle. Implement trust accounting software or procedures (QuickBooks with trust tracking, or legal-specific practice management with trust accounting). Establish monthly reconciliation procedures. Train yourself (or hire a bookkeeper) on trust accounting rules.

Critical: Trust account violations are the fastest path to disciplinary action for solo practitioners. Get this right from day one.

Malpractice Insurance

Don't practice a single day without coverage. Your prior firm's policy doesn't cover you after departure.

Secure individual policy or join a group policy. Verify coverage includes your practice areas (some policies exclude certain specialties). Understand claims-made vs. occurrence coverage (claims-made requires tail coverage if you cancel). Determine appropriate coverage limits ($500K/$1M is minimum; $1M/$3M more common for business litigation or PI). Budget $2,000-$8,000 annually depending on practice area and location.

Banking and Financial Infrastructure

Solo attorneys fail financially for one reason: they don't track their numbers. Build the financial infrastructure before you have revenue to track.

Banking Setup

Business checking account (separate from personal — I can't emphasize this enough). Business savings account for tax reserves (set aside 25-35% of every revenue dollar). Business credit card for practice expenses (builds credit history, simplifies expense tracking). Automated transfers from operating to tax savings account weekly or monthly.

Bookkeeping and Accounting

Select accounting software (QuickBooks Online is standard; Xero is viable alternative). Connect bank accounts for automatic transaction import. Set up chart of accounts specific to law practice (fees earned, case expenses, trust liability, etc.). Hire a bookkeeper or CPA familiar with law firm accounting — not a generalist. Establish monthly bookkeeping review and reconciliation. Set quarterly estimated tax payment schedule. Budget for year-end tax preparation ($800-$2,500 for solo practice).

Fee Structure and Billing

Decide your fee structure before your first client conversation. Indecision signals amateurism.

Hourly billing: Set your rate based on market research (check state bar surveys, Avvo, or ask peers). Typical solo rates: $150-$400/hour depending on market and experience. Require retainer deposits (typically 10-40 hours of estimated fees). Bill monthly, without exception. Use time-tracking software (many practice management platforms include this).

Flat fees: Appropriate for transactional work (estate plans, business formations, contract drafting). Scope definition is critical — what's included and what's extra. Collect 50% upfront, 50% on delivery. Track your actual hours on flat-fee matters to verify profitability.

Contingency fees: Standard for PI and some other plaintiff-side work. Understand state bar limits on contingency percentages (typically 33-40% pre-litigation, 40% litigation). Case cost tracking is essential — you advance costs, then recoup from settlement. Budget for case costs that may not be recovered.

Hybrid arrangements: Reduced hourly plus success fee. Monthly flat fee plus percentage of recovery. Define clearly in engagement letter.

Collections Process

Unbilled time and uncollected fees are the silent killers of solo practice revenue.

Bill monthly, every month, without fail. Require retainers for hourly work. Send invoice payment reminders at 15, 30, and 45 days. Have a collections escalation process (phone call at 60 days, demand letter at 90 days). Consider whether to accept credit cards (2-3% fee, but dramatically improves collection rates). Define in your engagement letter when work stops for non-payment.

Office and Workspace Infrastructure

You don't need marble floors and a receptionist on day one. You do need a functional workspace that projects competence.

Physical Office Options

Home office: Lowest cost. Acceptable for some practice areas if you have a dedicated, professional space. Not appropriate if you expect clients to visit regularly (estate planning, family law, criminal defense).

Executive suite/shared office: $300-$800/month. Receptionist, conference room access, professional address. Best for attorneys seeing occasional clients or needing a professional address without full office overhead.

Solo office lease: $1,000-$3,000/month depending on market. Full control, permanent signage, complete privacy. Appropriate once you have predictable revenue and regular client meetings.

Technology Infrastructure

Your technology stack determines your efficiency. Solo attorneys can't afford to be less productive than big-firm lawyers with support staff.

Essential hardware: Reliable laptop (not 5 years old — your computer is your primary tool). Dual monitor setup for document review and drafting. Backup hard drive or NAS (in addition to cloud backup). Scanner with OCR (document digitization is essential). Quality webcam and microphone for video consultations. Printer (yes, you still need one — court filings, client packets, signing documents).

Essential software: Practice management software (Clio, MyCase, PracticePanther, or similar). Document automation and assembly (LawYaw, Documate, or practice management integrations). Legal research (Westlaw, Lexis, or lower-cost alternatives like Fastcase). Time tracking (built into practice management or standalone like Toggl). Video conferencing (Zoom, Teams, or HIPAA-compliant option if needed). Secure file sharing (not Dropbox consumer — use business-tier with encryption or legal-specific platforms). Password manager (1Password, LastPass, Bitwarden). Cloud backup (Backblaze, Carbonite, or practice management with built-in backup).

Phone system: Business phone number (not personal cell). Professional voicemail greeting. Call forwarding to cell when out of office. Consider virtual receptionist service ($150-$400/month) for intake professionalism.

Client Intake and Management Systems

The intake process is where solo practices win or lose clients. Big firms have dedicated intake teams. You have yourself — which means your systems must be sharper.

Intake Process Design

Step 1: Initial Contact. Phone, email, or website form. Response within 2 hours during business hours (set an auto-reply if you're in court). Qualification questions to determine if the matter fits your practice.

Step 2: Conflict Check. Before any substantive discussion, check for conflicts with current and former clients. Maintain conflict database (most practice management software includes this).

Step 3: Consultation Scheduling. Offer consultation within 48-72 hours. Send confirmation with date, time, location, and what to bring. Include engagement letter for review before consultation.

Step 4: Consultation. Listen first, then advise. Explain fees and process. Provide written fee agreement if they retain.

Step 5: Engagement. Signed engagement letter before any billable work. Retainer deposit (if hourly) before work begins. Welcome packet with next steps and communication expectations.

Step 6: Ongoing Management. Regular case updates (proactive, not reactive). Monthly billing and status reports. Clear milestones and timelines.

Practice Management Software Selection

Your practice management platform is the operating system of your firm. Choose carefully.

Key features for solos: Client/matter management. Time tracking and billing. Document management and assembly. Calendar and task management. Conflict checking. Trust accounting (if applicable). Client portal. Mobile app access. Integration with accounting software.

Popular options: Clio ($39-$129/user/month) — Most comprehensive, strong integrations. MyCase ($49-$79/user/month) — Good all-in-one, strong client portal. PracticePanther ($39-$79/user/month) — Simple interface, good automation. Rocket Matter — Strong calendaring and task management, good reporting.

Selection criteria: Does it integrate with your accounting software? Does it handle trust accounting if you need it? Is the mobile app functional enough for court and client visits? Can you automate document assembly for your most common matters? Does the client portal look professional (clients will see it)?

Marketing and Business Development

The best solo practice in the world fails if nobody knows it exists. Marketing isn't optional — it's survival.

Foundation (First 30 Days)

Branding: Firm name (your name is fine — in fact, it's often better than invented names for solos). Logo (hire a designer on 99designs or Fiverr for $200-$500 — don't DIY). Color palette and typography (2-3 colors max, professional fonts). Business cards (yes, still essential for networking and referrals). Email signature with logo, phone, and website.

Digital presence: Domain name purchased and configured. Website live (even if simple — must include bio, practice areas, and contact). Google Business Profile claimed and optimized. LinkedIn profile updated to reflect solo practice. Avvo profile claimed and completed. State bar directory listing updated.

Contact infrastructure: Business email (not Gmail — yourname@yourfirm.com). Contact form on website. Phone number with professional voicemail. Automated email response for after-hours inquiries.

Ongoing Marketing (Months 2-12)

Referral network development: Identify 20 attorneys in complementary practice areas. Schedule coffee or lunch with each in first 90 days. Join local bar sections and committees. Attend networking events consistently (not once — consistently).

Content marketing: Write about your practice areas for your website blog. Publish on LinkedIn (where your professional network sees it). Speak at CLEs and bar events. Offer to write guest articles for local legal publications.

Client development: Ask satisfied clients for referrals (most won't think of it unless asked). Send holiday cards to current and former clients. Check in with former clients on significant case anniversaries. Request Google reviews at case conclusion.

Paid marketing (once revenue permits): Google Local Service Ads (for qualifying practice areas — appears above PPC). Google Ads for high-intent keywords (expensive but targeted). Avvo advertising (if your practice area is consumer-facing). Sponsored content in local legal or business publications.

Budget guidelines: Months 1-3: $0-$500/month (foundation building, networking costs). Months 4-6: $500-$1,500/month (website refinement, initial paid testing). Months 7-12: $1,500-$5,000/month (scaled paid marketing if ROI-positive).

The 90-Day Launch Timeline

Week 1-2: Form PLLC/PC. Open bank accounts. Secure malpractice insurance. Set up practice management software. Claim digital profiles (Google, Avvo, LinkedIn).

Week 3-4: Complete website (even if minimal viable product). Order business cards. Set up phone and email. Begin networking outreach. Establish bookkeeping procedures.

Month 2: Soft launch with referral network. First client intake (test your systems). Attend 2-4 networking events. Publish first blog post or LinkedIn article. Fine-tune billing and time tracking.

Month 3: Evaluate what's working. Adjust marketing based on early results. Consider first contractor hire (virtual assistant or bookkeeper) if overwhelmed by admin. Plan 6-month growth strategy.

The Solo Mindset

Infrastructure is essential. Mindset is what keeps you going when the infrastructure feels like it's failing.

Accept that the first 6 months are uncomfortable. You'll question the decision. You'll compare yourself to your former colleagues. You'll worry about money. This is normal. The attorneys who succeed are the ones who keep building through the discomfort.

Set boundaries immediately. Solo practice can consume every hour of every day if you let it. Define your office hours, response time expectations, and availability. Communicate them to clients in your engagement letter. Stick to them.

Invest in help before you think you can afford it. A bookkeeper who costs $300/month saves you 5 hours of billing time. A virtual assistant who costs $500/month handles scheduling and admin so you can bill more hours. The math almost always favors delegation.

Track your numbers obsessively. Billable hours. Collection rate. Average fee per matter. Client acquisition cost. These numbers tell you whether your practice is healthy before your bank account does.

Celebrate small wins. First client. First referral. First month where revenue exceeds expenses. First year where income matches your former salary. Solo practice is a marathon of small victories.

The Bottom Line

Going solo isn't about escaping bad bosses or avoiding partnership politics. It's about building a practice that reflects your values and serves your ideal clients. Generates income on yourterms.

But that practice doesn't build itself. The attorneys who thrive are the ones who treat the business side with the same rigor they bring to legal analysis. They set up the infrastructure deliberately. They track the numbers honestly. They invest in relationships consistently. And they keep showing up, even when the pipeline is thin and the uncertainty is thick.

The checklist above isn't a suggestion. It's the minimum viable infrastructure for a solo practice that survives its first year and thrives in its second. Check the boxes. Build the systems. Then get back to practicing law — which is, after all, why you went solo in the first place.
