What legal software do i need to start a law firm

9 min read

The software stack for a new U.S. solo or small law firm is built around five core categories:

  1. Legal practice management software
  2. Business email, calendar, and document software
  3. Trust accounting and business accounting tools
  4. PDF and electronic signature software
  5. Password management, multifactor authentication, and backup security

You do not need a dozen products on day one. Start with one practice management platform that connects clients, matters, documents, deadlines, time, billing, payments, and trust accounting.

Prices change. The official U.S. prices cited here were checked on September 20, 2026. At that time, Clio Manage Starter was $49 per user per month, Microsoft 365 Business Standard was $14 per user per month when paid annually, 1Password Business was $8.99 per user per month when paid annually, and Adobe Acrobat Pro for teams was $23.99 per license per month on an annual billed-monthly plan.

Legal practice management software should be your first major purchase. It gives the firm one place to manage client records, matters, documents, deadlines, billing, and communications.

Look for a platform that includes:

  • Client and contact management
  • Matter and case management
  • Secure document storage
  • Calendar and task management
  • Time and expense tracking
  • Invoicing and online payments
  • Client portals
  • Trust account ledgers
  • Trust reconciliation reports
  • Email and calendar synchronization
  • Data export if you change providers
  • Mobile access
  • User permissions and audit history

My Default Recommendation: Clio Manage Starter

Clio Manage Starter is a strong default for a new solo or small firm. Clio lists contact and matter management, document storage, time and expense tracking, online payments, legal accounting, and trust and operating account reconciliation among its features.

Clio's practice management platform also connects matter documents, calendar events, tasks, billing, client communications, and secure client collaboration.

Choose Clio Manage Starter if you want:

  • One central system instead of disconnected spreadsheets
  • Built-in legal accounting functions
  • A wide range of integrations
  • Room to add intake, automation, and reporting later

You may need a higher Clio plan or an add-on for advanced intake, client portals, automation, reporting, or practice-specific features.

Good Alternatives

MyCase Basic is a lower-cost alternative for firms that need case and billing tools. MyCase lists its Basic plan at $50 per user per month with annual billing or $60 per user per month with monthly billing. The plan includes case and contact management, time entry, invoicing, trust accounting, online payments, unlimited document storage, and a limited client portal.

MyCase lists three-way trust reconciliations under its separate MyCase Accounting add-on, priced at $39 per user per month. Confirm the exact trust-accounting features you need before comparing subscription prices.

PracticePanther Solo starts at $49 per user per month with annual billing. Its listed features include matter management, time tracking, payments, document templates, workflows, a client portal, and trust-account ledgers and reconciliation. Its Business Pro plan adds operating accounting, general ledger, accounts receivable, and expense management.

Smokeball may suit document-heavy firms with more staff and Microsoft Word and Outlook workflows. Its published plans cover billing, browser-based case management, document automation, intake, workflows, reporting, and accounting. Smokeball states that pricing depends on firm size, plan, contract term, and optional products.

PlatformBest fitImportant buying point
Clio Manage StarterNew firms wanting a broad legal platform with built-in accountingAdvanced intake and some workflow features require higher tiers or add-ons
MyCase BasicBudget-conscious firms wanting core case and billing toolsThree-way trust reconciliation is associated with the separate accounting add-on
PracticePanther SoloSolo lawyers wanting workflows, payments, and trust featuresFull operating and trust accounting requires Business Pro
SmokeballDocument-heavy firms with Microsoft Word and Outlook workflowsPricing is quote-based and depends on users, plan, and contract terms

2. Use Business Email and Document Software

You need a professional email address using your firm's domain. Do not use a personal Gmail or Outlook address for client communications.

Microsoft 365 Business Standard is a practical default for many new firms. It includes custom business email, Outlook, Word, Excel, Teams, OneDrive, SharePoint, calendar tools, and 1 TB of cloud storage per user. Microsoft also lists multifactor authentication, spam filtering, and malware protection among its business features.

Use Microsoft 365 for:

  • Firm email
  • Calendar appointments
  • Word pleadings, letters, and agreements
  • Internal document collaboration
  • Video meetings
  • Firm-wide templates
  • Basic cloud file storage

Google Workspace can work just as well if your firm already uses Gmail and Google Drive. Whichever platform you choose, use a managed business account with individual logins, multifactor authentication, and centralized access control.

Do not use a consumer cloud drive as your only document management system. Store matter documents in your practice management platform or a properly configured business document system with access controls, retention policies, and backups.

3. Handle Trust Accounting Correctly

Trust accounting is one of the most important software decisions for a new law firm.

Your system should help you distinguish among:

  • Client trust funds
  • Earned fees
  • Unearned retainers
  • Settlement funds
  • Operating-account money
  • Costs advanced on behalf of clients
  • Refunds and disbursements

ABA Model Rule 1.15 states that client and third-party property must be kept separate from the lawyer's own property. The rule also requires records and accounting for property held in connection with a representation. State bar rules may add requirements for reconciliation procedures, record retention, and reporting.

What to Verify Before Buying

Ask each vendor:

  1. Does the plan include trust-account ledgers?
  2. Does it support three-way reconciliation?
  3. Can it separate trust and operating accounts?
  4. Can it produce the reports required in your jurisdiction?
  5. Can it prevent trust funds from being applied incorrectly?
  6. Can your bookkeeper or accountant access reports without receiving unnecessary client access?
  7. Can you export complete trust records if you leave the platform?

Do not assume that a feature called "trust accounting" includes full legal accounting or state-compliant three-way reconciliation.

4. Add PDF and Electronic Signature Software

Law firms regularly receive, edit, combine, redact, annotate, and sign PDFs.

Adobe Acrobat Pro for teams is a reliable general-purpose choice. Adobe lists PDF editing, document conversion, redaction, form creation, document protection, and e-signature capabilities among its business features.

You may not need a separate e-signature product if your practice management platform includes appropriate signature workflows. Check whether the platform provides:

  • Signature requests
  • Automatic reminders
  • Completed-document records
  • Authentication options
  • Tamper-evident audit trails
  • Downloadable certificates
  • Secure storage of signed documents

For engagement letters and authorizations, native e-signature features may be enough. A dedicated product may make sense for high-volume signing, complex workflows, or stronger authentication requirements.

5. Use a Password Manager and Multifactor Authentication

A law firm should not store passwords in spreadsheets, browser notes, or shared email messages.

A business password manager lets the firm:

  • Create unique passwords
  • Share credentials without revealing them
  • Remove access when staff leave
  • Control access by role
  • Protect banking, court, email, and vendor accounts
  • Monitor compromised credentials

1Password Business is one option. Its published business plan includes shared passwords and sensitive data, role-based permissions, and security alerts. The listed price is $8.99 per user per month when paid annually.

Enable multifactor authentication for:

  • Email
  • Practice management software
  • Banking
  • Payment processors
  • Cloud storage
  • Legal research accounts
  • Domain registrar
  • Website administration
  • Payroll and accounting systems

Legal research software is essential for some firms but may not be the first purchase for every practice.

You are more likely to need a paid research platform immediately if you:

  • Handle litigation
  • Research complex statutory or regulatory issues
  • Practice appellate law
  • Advise clients in heavily regulated industries
  • Need citator and authority-validation tools
  • Regularly research across multiple jurisdictions

Possible providers include Westlaw, Lexis+, Bloomberg Law, and vLex. Compare them based on the jurisdictions, practice areas, primary sources, citator functions, docket access, and AI features you actually need.

Do not buy a broad legal research subscription solely because it includes AI drafting. You remain responsible for checking authorities, facts, citations, and legal reasoning.

Legal AI can help with summarization, document review, drafting, and workflow automation. It is not a substitute for the systems that run the firm.

ABA Formal Opinion 512 says lawyers using generative AI must consider duties involving competence, confidentiality, communication, supervision, candor to the tribunal, and reasonable fees.

Before putting client information into an AI product, check:

  • Whether the vendor uses customer data to train models
  • Where the vendor stores data
  • Whether the vendor retains prompts and uploads
  • Whether the product supports matter-level access controls
  • Whether the vendor provides audit logs
  • Whether the product cites source material
  • Whether your engagement terms address AI use
  • Whether your state bar has issued additional guidance

ABA Model Rule 1.6 requires lawyers to make reasonable efforts to prevent unauthorized access to or disclosure of information relating to a client's representation.

Software You Can Usually Postpone

You usually do not need these products before opening your doors:

  • A separate CRM
  • A separate document management platform
  • A custom client portal
  • Advanced legal AI
  • E-discovery software
  • A complex phone system
  • Project management software separate from your practice management platform
  • Custom document automation
  • A large on-premises server
  • Multiple overlapping cloud-storage services

Add these tools when your caseload, staff size, or practice area creates a clear operational need.

A Sensible First-Year Buying Order

  1. Set up your domain and Microsoft 365 or Google Workspace.
  2. Choose legal practice management software before accepting clients.
  3. Configure trust and operating accounts with your bookkeeper or accountant.
  4. Create matter, document, billing, and naming conventions.
  5. Enable multifactor authentication and password management.
  6. Test client intake, conflict checking, engagement letters, billing, and trust deposits.
  7. Add legal research, document automation, CRM, or AI when the workflow justifies the cost.

Bottom Line

Start with the smallest secure stack that can manage a matter from intake through billing and trust reconciliation. For most new U.S. solo firms, that means Clio Manage Starter, Microsoft 365 Business Standard, a business password manager, and reliable PDF software. Confirm that the practice management plan supports the trust-accounting and reconciliation functions required in your jurisdiction before you accept client funds.
