LeanLaw Review (2026): Legal Billing and Trust Accounting for QuickBooks Online Firms

LeanLaw is for firms whose bookkeeper won't give up QuickBooks Online. It adds legal billing and trust accounting on top, and syncs both ways. The prices are published; the renewal clause deserves a calendar reminder.

Verdict at a glance

Recommended for

Small and midsize firms already on QuickBooks Online that want legal billing and IOLTA trust accounting, including contingency-fee firms.

Bottom line

If you run your firm's books in QuickBooks Online and want legal billing and trust accounting without switching systems, LeanLaw is a strong fit; start month-to-month, pick one system as your trust ledger, and set the 60-day renewal reminder on day one.

Legal time, billing and IOLTA trust accounting built natively on QuickBooks Online, with a two-way sync. Core is $55 and Pro $75 per user per month; contingency and larger-firm plans are quoted. Contracts auto-renew unless you give 60 days' written notice, fees are non-refundable, and your LeanLaw data can be deleted right after termination.

Not for

Firms not on QuickBooks Online, or firms that want all-in-one practice and document management.

Quick answer

Bottom line: LeanLaw is for small firms whose books already live in QuickBooks Online and who want legal billing and trust accounting without leaving it. Core is $55 and Pro $75 per user per month, with Contingency and Elite quoted (vendor claims, checked October 15, 2026). There's a free trial. The trap is the renewal clause: contracts auto-renew unless you give written notice 60 days before the term ends, and the clause on renewal price changes is ambiguous, so calendar the deadline on day one and ask LeanLaw in writing to send renewal pricing before it.

LeanLaw adds legal time tracking, billing, e-payments and IOLTA trust accounting on top of QuickBooks Online, with a two-way sync, so your accounting stays where your bookkeeper wants it. Published prices are Core $55 and Pro $75 per user per month; the Contingency plan (settlements and liens) and Elite plan are quoted. LeanLaw offers a free trial. Month-to-month plans can be cancelled at the end of a billing period, while annual and multi-year deals run for their full term. Its terms auto-renew unless you give written notice 60 days before the term ends, fees are non-refundable, and LeanLaw-side data can be deleted right after termination. A strong fit for QuickBooks firms; not a full practice management system.

We built this review from LeanLaw's own website, pricing page and terms of service, plus our overall reading of public user feedback. Everything was checked October 15, 2026. Prices are vendor claims and change, so confirm with LeanLaw.

What does LeanLaw actually do?#

Most legal billing tools want to be your accounting system too. LeanLaw goes the other way: QuickBooks Online stays the general ledger, and LeanLaw handles the legal-specific parts and syncs them in. From LeanLaw's pricing page:

  • Core: time and expense tracking, e-payments, professional invoices, a reporting dashboard, IOLTA trust accounting (the pooled client trust account most firms are required to keep), and two-way QuickBooks Online sync.
  • Pro: everything in Core, plus three custom invoice templates, LEDES files (the standard e-billing format many insurers and corporate clients require), precise user permissions and matter-based accounting.
  • Contingency: a settlement wizard from matter opening through disbursement, lien management and tracking, automated settlement statements, and case-profitability reporting. Built for PI and other contingency-fee practices.
  • Elite: everything above, plus unlimited invoice templates, custom reporting, compensation tracking and a dedicated success manager.

It isn't a full practice management system. Document management, intake and deep matter workflows live elsewhere.

What this means for you: If your accountant already reconciles your firm in QuickBooks Online, LeanLaw lets you add legal billing without a migration fight. If you're not on QuickBooks Online, it's the wrong tool.

How much does LeanLaw cost?#

From leanlaw.co/pricing (vendor claims, checked October 15, 2026):

LeanLaw published plans

Add your QuickBooks Online subscription, which you pay Intuit for separately. LeanLaw says annual billing is available and lowers the effective monthly price, but annual rates are quoted in a demo rather than published; confirm with LeanLaw.

What are LeanLaw's contract terms?#

LeanLaw's pricing FAQ says month-to-month subscriptions can be cancelled at the end of a billing period, annual and multi-year agreements run for their committed term, and Elite and Contingency follow the terms in your contract.

Its terms of service add the details, paraphrased:

  • Auto-renewal. The initial term comes from your order form, then the agreement renews for successive terms unless either side gives written notice of non-renewal at least 60 days before the current term ends.
  • Renewal price changes. LeanLaw can change fees for a renewal term if it gives you the new amounts within 60 days of the term's expiration. The wording doesn't make clear whether that means at least 60 days before, or any time in the last 60 days.
  • Payment. Fees are paid in advance and non-refundable. Late amounts accrue 1.5% interest a month plus collection costs, and access can be suspended if a payment is five or more days late.
  • Data after termination. LeanLaw has no obligation to keep data such as time entries, draft invoices, email and calendar records after the agreement ends; it may be deleted immediately. Posted financials still live in your QuickBooks Online file.
  • Suspension for trust issues. LeanLaw can suspend service if a court finds you in violation of law or a bar association requests access to trust accounts by subpoena.

How hard is LeanLaw to set up?#

Low to moderate. You connect QuickBooks Online, map your accounts, set rates and invoice templates, and bring over trust balances. LeanLaw says an onboarding specialist sets it up for your firm type and billing model in a live session.

The decision that matters most isn't technical. With a two-way sync, pick one system as the authoritative trust ledger and reconcile the other to it. If both systems are treated as the record for client money, your three-way reconciliation (matching the bank statement, the trust ledger and each client's balance) can stop adding up.

What do users say about LeanLaw?#

We read public user feedback and looked for patterns.

What users like. The native QuickBooks Online integration is the headline, followed by helpful support and reasonable pricing.

What frustrates them. Timekeeping feels clunkier than in dedicated time-tracking tools, and some users point to reconciliation risk when firms treat both LeanLaw and QuickBooks as the system of record for trust.

Buyer tips before you sign#

  1. Start month-to-month. Lock into annual only after a full billing cycle.
  2. Set the 60-day non-renewal reminder on day one, and get renewal pricing in writing before it.
  3. Export time entries and draft invoices before the term ends if you might leave.
  4. Choose your trust ledger of record and reconcile to it monthly.
  5. Contingency firms: ask for the Contingency plan price and terms in writing, since they're contract-specific.

Pros and cons#

Pros

  • Native QuickBooks Online with two-way sync.
  • Trust accounting on every plan.
  • Contingency workflow for settlements and liens.
  • Published Core and Pro prices, free trial.

Cons

  • QuickBooks Online required.
  • 60-day non-renewal notice.
  • Non-refundable fees.
  • LeanLaw data deletable right after termination.

How does LeanLaw compare?#

Rocket Matter is a fuller billing-first practice management system, with built-in accounting on its top tier. Bill4Time is another dedicated time and billing tool worth pricing alongside it. TrustBooks focuses narrowly on trust accounting for firms that keep billing elsewhere.
