Law Firms

Law firm software is not one product. It is ten categories of tools: practice management, case management, billing, trust accounting, CRM and intake, document management, e-signature, legal research and AI, answering services, and accounting. Most firms start with one or two and add the rest as they grow.

If you are a solo attorney or a firm of two to 20 lawyers, the usual first purchase is a practice management platform. Several of them bundle billing, trust accounting and a client portal in one subscription. Larger or litigation-heavy firms tend to add case management, document management and legal AI.

This page maps each category: what it does, who needs it, and a few well-known products with facts taken from vendor pages. We do not name winners here. Each section points to a category guide that compares products in depth.

How We Evaluate Legal Software

Every price, plan and feature below comes from the vendor's own pages, opened on October 27, 2026. We report what vendors document and leave out what we could not confirm. Our scoring approach is on the how we test page.

The 10 Types of Law Firm Software

Prices are per user per month unless noted. Pricing checked October 27, 2026.

1. Practice Management

Practice management software is the firm's operating system: contacts, matters, calendar, documents, time, billing and a client portal. Any firm with more than a handful of matters needs one. Our guide to legal practice management software compares the leaders.

  • Clio Manage: plans are Starter, Core, Signature and Elite. The pricing page shows "starting at $49/user," a 7-day free trial without a credit card, and SOC 2 Type II. It says Starter has legal accounting built in. clio.com
  • MyCase: Basic $50, Pro $100 and Advanced $130 billed annually ($60, $120 and $150 monthly). It lists a 10-day trial with no card and unlimited eSignature from Pro up. mycase.com
  • Smokeball: four plans (Bill, Boost, Grow, Prosper+), with pricing by custom quote. Trust accounting appears in the entry-level Bill plan. smokeball.com

2. Case Management

Case management tracks stages, tasks, deadlines and documents inside each matter, often for high-volume work such as personal injury. Vendors blur the line with practice management, so check what each plan includes. See our guide to legal case management software.

  • Filevine: its LOIS platform covers matter management, document assembly, intake and billing. Packages are custom quotes; a free LOIS Explore tier for its AI tools needs no credit card. filevine.com
  • Litify: built on Salesforce, with intake, matter, document, and time and billing tools. It names personal injury, insurance defense, immigration and corporate legal teams. The page lists no pricing, only a demo. litify.com
  • CASEpeer: built for personal injury firms. Basic is $90, Pro $130 and Advanced $160 per user. A demo is offered; no trial is listed. casepeer.com

3. Billing and Time Tracking

These tools capture time, build invoices and collect payments. Hourly firms rely on them most, though flat-fee and contingency firms still track expenses and reports. Our guide to legal billing software goes deeper.

  • Bill4Time: Time & Billing is $39 billed annually ($49 monthly). Legal Pro, $59 annually ($69 monthly), adds trust accounting, LEDES export and a conflict checker. The trial is 14 days, no card. bill4time.com
  • TimeSolv: billed per active user with no long-term contract and a 10-day free trial. It lists trust accounting and LEDES billing, but the page shows no per-user plan prices. timesolv.com

4. Trust Accounting and Payments

Client money held in trust must stay separate from the firm's own funds. ABA Model Rule 1.15 states the general rule; each state adopts its own version. Every firm that holds retainers or settlement funds needs a way to track client ledgers.

  • LawPay: a $19 monthly base plan with no contract. Visa, Mastercard and Discover cost 2.99% + $0.30. The page says the plan includes trust account protection and IOLTA compliance; pass-through fees may apply. lawpay.com
  • CosmoLex: Launch $49, Core $99 and Pro $129 monthly. It lists "trust accounting & ledgers." Trial length is not stated. cosmolex.com
  • MyCase: trust accounting is in Basic. A separate MyCase Accounting add-on ($39) lists three-way trust reconciliations on Pro and Advanced.

5. CRM and Client Intake

Legal CRM and intake tools capture leads, send forms and engagement letters, check conflicts and track follow-up. Firms that buy marketing or live on referrals need them most. See our guide to the law firm CRM options.

  • Lawmatics: Essential, Premium and Enterprise, with a three-user minimum on the first two. Pricing is by demo. Its integrations page lists matter-data syncs to Clio, MyCase, Filevine and Smokeball. lawmatics.com
  • Clio Grow: intake forms in five languages, conflict checks at intake and a lead inbox. It is an add-on, and the Elite plan includes it. clio.com
  • Lead Docket: a lead-management product whose site footer names Filevine, Inc. Pricing is by custom quote. leaddocket.com

6. Document Management and Automation

Document management stores, versions and secures files and email by matter. Automation fills templates from client data. Firms need both once shared folders stop being safe or fast enough. Our guide to legal document management software covers the options.

  • NetDocuments: a cloud-native system with email filing, ethical walls and data loss prevention. It cites 150+ integrations, including Microsoft 365, DocuSign and Clio. Pricing is by sales contact. netdocuments.com
  • iManage: document and email management with a Security Policy Manager, aimed at global, midsize and small firms. Pricing is by demo. imanage.com
  • Gavel (formerly Documate): document automation at $83 (Lite), $290 (Pro) and from $417 (Scale) monthly, with a 7-day trial on the lower plans. Its Standard price appears twice at different amounts, so confirm it. gavel.io

7. E-Signature

E-signature tools collect signatures on engagement letters, retainers and settlement papers. Many practice management and intake products include them, so standalone tools matter mainly when you sign outside your main system.

  • DocuSign eSignature: per-user Personal ($10 monthly, $120 billed annually), Standard ($25, $300) and Business Pro ($40, $480). Enterprise is by sales. docusign.com
  • Dropbox Sign: Essentials is $15 monthly for one user and Standard is $25 per user monthly for two or more. Premium is by quote. All list unlimited signature requests. sign.dropbox.com

8. Legal Research and Legal AI

Research tools find case law, statutes and secondary sources. Newer AI assistants also draft and summarize. Any lawyer who writes briefs or advises on unfamiliar law may use one, but every output needs attorney review.

  • Lexis+ with Protégé (formerly Lexis+ AI): research, drafting and Shepard's citation checking, with links to iManage, SharePoint and NetDocuments. Trials are by request; the page shows no pricing. lexisnexis.com
  • CoCounsel Legal: Thomson Reuters' assistant draws on Westlaw and Practical Law. Tabular Analysis can review up to 10,000 documents against 100 questions. Plan pages split firms under and over 10 attorneys; prices are not shown. thomsonreuters.com
  • Harvey: AI for law firms and in-house teams, with Vault, Knowledge and Agents products. It lists SOC 2 Type II and ISO 27001 badges. Pricing is by demo. harvey.ai

9. Answering Services and Virtual Receptionists

Live answering services pick up calls, capture intake details and route urgent matters. Solo and small firms that miss calls while in court need them most. Our guide to the attorney answering service category compares providers.

  • Smith.ai: Starter $300 (30 calls), Basic $810 (90) and Pro $2,100 (300) monthly, with 24/7 live agents. Conflict checks cost $0.50 per call, and a 30-day money-back guarantee applies. smith.ai
  • Ruby: receptionist plans by minutes: 50 for $250, 100 for $395, 200 for $720 and 500 for $1,725 monthly, with 24/7 answering. No trial is listed. ruby.com

10. Accounting

General accounting software keeps the firm's operating books, separate from client trust funds. Almost every firm needs it, and billing tools often sync with it: Bill4Time, TimeSolv and CASEpeer all list QuickBooks integrations.

  • QuickBooks Online: promotional prices (50% off for three months) of $19 Simple Start, $42.50 Essentials, $70 Plus and $170 Advanced. A 30-day free trial is listed. quickbooks.intuit.com
  • Xero: Early $2.70 for six months, then $27; Growing $5.90, then $59; Established $9.70, then $97. The introductory offer ends November 2, 2026. xero.com

Which Software Does Your Firm Need?

Pricing checked October 27, 2026. Prices appear in the category sections above.

Practice area shifts the mix. CASEpeer describes tracking treatment, liens and settlements for personal injury firms. Litify names personal injury, insurance defense and immigration, and Filevine has pages for family law, immigration and criminal defense.

All-in-One Suite or Best-of-Breed Stack?

An all-in-one platform keeps data in one place and gives you one bill and one support contact. MyCase Pro, for example, lists CRM, eSignature and billing in a single plan. A best-of-breed stack lets you pick a stronger tool per job but adds integrations to maintain.

Vendors document those links: NetDocuments cites 150+ integrations, and Lawmatics lists syncs to several practice management products. Ask each vendor what data moves automatically and what your staff must re-enter.

Security and Ethics Checklist

This is general information, not legal advice. Your state bar's rules control.

  • Access controls: ask about encryption and role-based permissions. Clio's page lists custom roles and permissions, with unlimited roles on Signature and Elite.
  • SOC 2: the AICPA describes SOC 2 reporting as an examination of controls relevant to security, availability, processing integrity, confidentiality or privacy. Clio and Harvey list SOC 2 Type II. Ask for the report and check its scope and date.
  • Data and AI training: Clio's page says its enterprise offering has zero-retention agreements with LLM providers. Ask every AI vendor whether your data trains models.
  • Generative AI ethics: the ABA Standing Committee on Ethics and Professional Responsibility issued Formal Opinion 512 on July 29, 2024, its first on generative AI (full opinion, PDF). It points to duties of competence, confidentiality, communication and reasonable fees. Per the ABA's release, a lawyer generally cannot bill a client for learning how to use an AI tool.

FAQ

What is the best legal software for small law firms?

There is no single best product. Small firms usually start with practice management that includes billing and trust accounting; Clio Manage, MyCase and Smokeball are examples with listed plans. Compare per-user cost, trust accounting, included e-signature and AI, and trial length before choosing.

What is the best legal software?

It depends on the job. Legal software spans ten categories, so "best" only makes sense inside one, such as billing or document management. This page does not rank products; the category guides linked above compare them in more detail.

Do law firms need cloud-based software?

Not by rule, but many tools are cloud-based. NetDocuments calls itself cloud-native, and Smokeball's Boost plan lists a fully browser-based platform. Cloud tools shift hosting to the vendor. You still need to check security, data export and your state bar's confidentiality guidance.

Can lawyers use AI tools ethically?

ABA Formal Opinion 512 says lawyers using generative AI must weigh competence, confidentiality, communication and fee rules. Review every output before relying on it. State rules differ, so check yours. This is general information, not legal advice.
