The right software for a law firm depends on its size. Most solo and small firms run on a practice management system such as Clio or 8am MyCase, plus accounting, document automation and an artificial intelligence (AI) contract review tool. Mid-size and large firms add a document management system, enterprise billing, transaction management and e-discovery software.

Key takeaways

  • Choose practice management first. It holds matters, calendars, time and invoices, and most other tools connect to it.
  • Solo and small firms do best with all-in-one tools that publish their prices. Large firms buy specialized systems such as Aderant and iManage, which are sold by quote.
  • Billing and accounting tools must keep client trust funds separate from operating funds, so check trust accounting before you buy.
  • AI tools now handle contract review, drafting and document review. Read each tool's data retention and training terms before you upload client files.

Last updated October 29, 2026. We checked every vendor's name, owner and published price on its own website in October 2026. Gavel makes Gavel Workflows and Gavel Exec. Relativity, which acquired Gavel in June 2026, makes Relativity aiR.

What software does a law firm need?

Most firms need software for practice management, documents, billing and accounting, client intake, document automation and drafting, plus litigation or deal support. The table lists our picks for each category by firm size, and the sections below explain each one.

What is the best practice management software for law firms?

Practice management software keeps a firm's matters, contacts, calendar, deadlines, time entries and invoices in one system. Clio and 8am MyCase fit most solo and small firms. Litify and Aderant are built for larger firms with more complex workflows and reporting.

You will also see the terms case management and matter management. Case management tracks litigation, matter management covers transactional work as well, and practice management adds time, billing and trust accounting. Most current products cover all three.

8am MyCase was renamed in August 2025, when its parent company AffiniPay became 8am. Gavel Workflows integrates with Clio Manage; see Gavel Workflows integrations.

What is the best document management software for law firms?

A document management system (DMS) files documents and email by client and matter, keeps version history and controls who can open each file. iManage and NetDocuments are the standard at mid-size and large firms. LexWorkplace and Smokeball fit smaller firms.

Look for version control, ethical walls between matters, Outlook filing and audit trails.

What is the best billing and time tracking software for law firms?

Billing software turns time entries into invoices, handles retainers and different rate structures, and collects payment. TimeSolv and Bilr suit small firms that bill by the hour. Large firms usually capture time with Intapp Time and bill through their practice management or financial system.

8am LawPay was called LawPay until the 8am rebrand in August 2025.

What accounting and trust accounting software do law firms use?

Law firm accounting has to keep client funds in trust separate from the firm's own money and reconcile the trust account. The American Bar Association (ABA) sets that duty in Model Rule 1.15, and each state has its own version. Many small firms use QuickBooks Online as the general ledger with LeanLaw on top for legal billing and trust accounting.

Prices from each vendor's website, checked October 2026. “Quote” means the vendor doesn't publish a price.
ToolWhat it doesBest forStarting price
QuickBooks OnlineGeneral small-business accounting: bookkeeping, invoicing, bill pay, payroll and reportingSmall firms (not built for law firms)Free plan; paid plans from $38 per month
LeanLawLegal time, billing, trust accounting and payments that runs on QuickBooks OnlineSmall and mid-size firms$55 per user per month (Core)
ZipBooksGeneral accounting and invoicingSolo firms on a tight budgetFree plan; paid plans from $15

Large firms usually run accounting inside a financial management suite such as Aderant. PCLaw, a long-running on-premises legal accounting product, is now sold through a LexisNexis and LEAP joint venture, and versions from 2021 and earlier are no longer supported, so firms still on it should plan a move.

What is the best client intake software for law firms?

Client relationship management (CRM) software tracks prospective clients from first contact to signed engagement, sends follow-ups and runs conflict checks. Lawmatics and Law Ruler are built for law firms.

Prices from each vendor's website, checked October 2026. “Quote” means the vendor doesn't publish a price.

LawmaticsLegal CRM with intake, marketing automation, e-signature, conflict checks and integrations with Clio and 8am MyCaseSolo to large firmsQuote; some plans require 3 users
Law RulerLegal CRM with intake forms, document assembly, e-signature and email, text and voice campaignsSolo to large firmsQuote

Gavel Workflows also handles intake. Clients answer a guided questionnaire, and the answers fill the engagement letter and the other documents for the matter. See legal intake software.

What is the best document automation software for law firms?

Document automation turns a firm's templates into questionnaires that assemble finished documents from the answers. Our pick is Gavel Workflows, which we make. Gavel Workflows is legal document automation software for law firms.

  • Build questionnaires on your own templates, with logic that includes or removes clauses based on the answers.
  • Share questionnaires with clients through a client portal, or use them internally to assemble documents.
  • Start from the legal template library, or have Gavel's team build the workflow for you.
  • Connect to Clio Manage, DocuSign and Zapier.

Which AI software should a law firm use for contracts?

AI contract tools review agreements against a playbook, suggest redlines and draft clauses. Gavel Exec does this inside Microsoft Word and on the web. Draftwise drafts from a firm's own precedent, and Thomson Reuters' Drafting Assistant supports transactional and litigation drafting.

For ten tools compared on Word redlining, playbooks, benchmarking and price, see best AI contract review tools for lawyers. Before you upload client documents to any AI tool, confirm it has zero data retention agreements with its AI model providers and won't train on your data. The ABA's Formal Opinion 512 (July 29, 2024) sets out lawyers' duties when they use generative AI. Solo lawyers choosing among general assistants, legal research tools and contract review can start with our guide to AI tools for solo lawyers.

What is the best transaction management software for law firms?

Transaction management software runs a deal's closing checklist, collects signature pages and assembles the closing set. SimplyAgree, iManage Closing Folders, Litera Transact and Legatics are the main options built for law firms.

Prices from each vendor's website, checked October 2026. “Quote” means the vendor doesn't publish a price.

What is the best e-discovery software for law firms?

E-discovery software processes, searches and reviews large volumes of electronic documents for litigation and investigations. Relativity aiR, DISCO and Everlaw handle large and complex matters. Logikcull offers pay-as-you-go pricing, which suits smaller matters.

Relativity renamed RelativityOne to Relativity aiR in September 2026. Gavel Exec is integrated with Relativity aiR; see Gavel Exec and Relativity aiR.

What project and knowledge management tools do law firms use?

Project management tools track tasks and deadlines across matters, and knowledge management tools help lawyers find the firm's past work. Small firms often use general tools such as Trello or Smartsheet. Large firms add HighQ, SharePoint and Litera Foundation.

Prices from each vendor's website, checked October 2026. “Quote” means the vendor doesn't publish a price.

Estate planning firms use Gavel Workflows to assemble wills and trusts from client intake. See estate planning software and how estate planning lawyers use AI.

Where can a law firm find freelance lawyers?

Freelance marketplaces let a firm add capacity without hiring. LAWCLERK connects law firms with U.S.-based freelance attorneys for hourly or flat-fee projects and charges no subscription. Lawtrades serves in-house legal teams and startups more than law firms.

How do you choose software for your law firm?

Start with practice management, then add tools that connect to it. Run each finalist on a real matter before you commit.

  1. List the jobs to cover. Write down where time goes today: intake, drafting, billing, document filing, review.
  2. Check integrations. Confirm each tool connects to your practice management system and to Microsoft 365 or Google Workspace.
  3. Confirm security. Ask for a SOC 2 (System and Organization Controls 2) Type II report, encryption details and data retention terms. For AI tools, get a written commitment not to train on your data. See security questions to ask legal software vendors.
  4. Compare total cost. Add per-user prices, implementation and onboarding fees, payment processing and any annual commitment.
  5. Test with the people who will use it. Have a lawyer and a staff member run a live matter through the trial.

ABA Model Rule 1.6 requires reasonable efforts to protect client information, which applies to every vendor that stores it.

How much does law firm software cost?

Practice management with a published price runs from $49 to $79 per user per month among the tools in this guide. Payments, document management and AI tools add to that: 8am LawPay starts at $19 per month plus processing fees, LexWorkplace at $395 per month for three users and Gavel Exec at $160 per user per month. Enterprise systems such as Aderant, iManage and Relativity aiR are priced by quote.

Frequently asked questions

What software do most law firms use?

Most firms run a practice management system such as Clio or 8am MyCase, Microsoft 365 for email and documents, accounting software that handles trust accounts and a payment processor such as 8am LawPay. Larger firms add a document management system such as iManage or NetDocuments.

What is the best software for a solo or small law firm?

Start with practice management that includes billing and trust accounting, such as Clio, 8am MyCase or CARET Legal. Add document automation such as Gavel Workflows for documents you produce often, and an AI contract review tool such as Gavel Exec if you negotiate agreements.

What software do large law firms use?

Large firms commonly run Aderant for financial and practice management, iManage or NetDocuments for documents, Intapp Time for time capture, Litera products for drafting and closings, and Relativity aiR, DISCO or Everlaw for e-discovery.

Is cloud-based legal software safe for client data?

It can be. Ask each vendor for a SOC 2 Type II report, encryption in transit and at rest, and clear terms on who owns and keeps your data. For AI tools, also ask for zero data retention agreements with AI model providers and a written commitment not to train on your documents.

Do law firms need AI software?

A firm can run without it, but AI tools now cut time on contract review, drafting and document review. Choose tools built for legal work, check their data terms and have a lawyer review every output, as ABA Formal Opinion 512 expects.
