The best law firm accounting software
Starting priceSee website
Free planNo
QuickBooks is the default bookkeeping tool for US small businesses, and law firms can use it for general accounting, invoicing, payroll, and expense tracking. Its homepage highlights AI features that automate recurring tasks and forecasts grounded in live business data, plus more than 800 integrations with other business tools.
The gap for law firms is trust accounting. QuickBooks does not offer built-in IOLTA trust accounting or three-way reconciliation, so firms that hold client funds need a legal add-on like LeanLaw or a separate trust ledger. For firms that keep trust funds elsewhere or use a dedicated trust tool, QuickBooks remains the most widely supported general ledger a bookkeeper can work with.
What we like- Trusted by 10 million businesses
- 800 plus integrations
- Strong invoicing and payroll
Watch out for- No built-in trust accounting
- Needs a legal add-on for matter billing

Starting price$27 per month
Free planNo
Xero is a cloud accounting platform used by 5 million customers worldwide, with an Early plan at $27 per month that covers quotes, invoicing, bank reconciliation, and receipt capture. The Growing plan at $59 per month adds dashboards and budget tools, while Established at $97 per month adds project tracking and expense claims. Its AI assistant, JAX, handles routine tasks and answers business questions from live data.
Like QuickBooks, Xero is general accounting software, not legal software. It lacks trust accounting, matter-based billing, and legal reporting, so law firms need a practice tool alongside it. For small firms that want clean, affordable bookkeeping and handle trust funds in a dedicated system, Xero is a strong choice.
What we like- Clean interface
- Early plan from $27 per month
- Smart receipt capture
- Strong reporting
Watch out for- No built-in trust accounting
- US payroll features trail QuickBooks

Free planNo
CosmoLex describes itself as the only fully built-in matter management and firm accounting solution for small and mid-sized law firms. It connects matter management, billing, payments, and firm accounting in one cloud system, with trust accounting tools that support three-way reconciliation and audit trails. A free trial is available, and its homepage shows recent positive user reviews on ease of use and support.
The trade-off is ecosystem size: CosmoLex has fewer third-party integrations than Clio or QuickBooks, though it covers email and payment processing. Pricing is quote-based. For firms that want to drop QuickBooks entirely and run accounting inside their practice software, CosmoLex is the strongest fit.
What we like- Only matter-centric system with fully built-in accounting
- Trust compliance tools
- Free trial
Watch out for- Pricing not published on the homepage
- Smaller ecosystem than Clio

Starting price$55 per user per month
Free planNo
LeanLaw is legal billing software built specifically for firms using QuickBooks Online. Its Core plan starts at $55 per user per month, with Pro at $75 per user per month and custom Elite and Contingency plans. It connects time and expense entries, invoice review, payments, client trust records, and reporting in one workflow, with two-way QuickBooks Online sync so invoices, payments, and trust activity land in the same books the bookkeeper works in.
The requirement is clear: an active QuickBooks Online subscription is mandatory, and QuickBooks Desktop is not supported. A 7-day free trial needs no credit card. For firms already committed to QuickBooks Online that want legal billing without a second ledger, LeanLaw is the natural choice.
What we like- Built on QuickBooks Online
- Trust accounting included
- 7-day free trial
Watch out for- Requires QuickBooks Online
- QuickBooks Desktop not supported

PracticePanther is an all-in-one legal practice platform with case management, calendaring, client communication, billing, and payments.

It is approved by more than 70 bar associations and offers a 7-day free trial with no credit card needed.
Plans run from Solo through Essential, Business, and Business Pro, with pricing available on request rather than on the homepage. For firms that want practice management plus real accounting depth in one platform, PracticePanther is a strong contender.
What we like- Fully embedded accounting with trust reconciliation
- 7-day free trial
- 70 plus bar approvals
Watch out for- Pricing not published on the homepage

Centerbase is an AI-powered business platform built for mid-sized law firms, unifying billing and collections, accounting, matter management, and firm intelligence in one native platform. It requires no QuickBooks dependency, reconciles trust automatically, and offers passive time capture across Outlook and Word so work actually gets billed. Its homepage cites mid-sized firms losing 180,000 to 400,000 dollars a year in unbilled time from disconnected systems.
The mid-market focus means solos may find it heavier than needed, and pricing is quote-based. For mid-sized firms that want one source of truth for every matter, client, and dollar, Centerbase is a compelling option.
What we like- Built for mid-sized firms
- No QuickBooks dependency
- Passive time capture
Watch out for- Mid-market focus may price out solos
- Newer brand than Clio or PracticePanther
How we chose
We compared law firm accounting tools on trust accounting support, general ledger depth, billing and payment features, practice management coverage, bar association approval, and fit for different firm sizes, using vendor homepages opened for this review. Prices are quoted only where the vendor publishes them on its homepage; otherwise they are listed as "See website". Tools without published prices require a quote.
What to check before you buy
Start with trust accounting. If your firm holds client funds, your software must handle IOLTA accounts, three-way reconciliation, and audit trails that satisfy your state bar. CosmoLex, PracticePanther, and Centerbase build this in, while QuickBooks and Xero do not. Ask the vendor to show a three-way reconciliation in a live demo, not just in marketing copy.
Next, decide whether you want one system or two. A single platform with built-in accounting reduces double entry and reconciliation work, but it may limit your bookkeeper's flexibility. A two-system setup with QuickBooks plus LeanLaw keeps the general ledger your bookkeeper knows, at the cost of managing a connection. Match the choice to your firm's size and your bookkeeper's skills.
Finally, test the billing workflow end to end during the trial. Record time, generate an invoice, apply a trust payment, and run a month-end report. Check how the tool handles split billing, flat fees, and contingency matters if your practice needs them. A tool that looks good in a demo can still slow billing day down, and billing speed directly affects cash flow.
Frequently asked questions
What is the best accounting software for a small law firm?
CosmoLex and PracticePanther suit small firms that want practice management plus built-in accounting in one system. LeanLaw suits firms already on QuickBooks Online. Xero and QuickBooks work for general bookkeeping but need a separate trust tool.
Does QuickBooks handle trust accounting?
No. QuickBooks does not include built-in IOLTA trust accounting or three-way reconciliation. Firms that hold client funds should pair QuickBooks with a legal tool like LeanLaw or choose a platform with built-in trust accounting, such as CosmoLex or PracticePanther.
Is CosmoLex better than Clio for accounting?
CosmoLex has deeper built-in accounting, since its accounting is native to the platform rather than layered on top of practice management. Clio has a larger user base, more integrations, and wider bar approval. Firms that prioritize accounting depth should favor CosmoLex; firms that prioritize ecosystem and scale should favor Clio.
How much does law firm accounting software cost?
Published starting prices in this review range from $27 per month for Xero to $55 per user per month for LeanLaw. Clio, MyCase, CosmoLex, PracticePanther, and Centerbase price by quote, so costs depend on firm size and features. Always confirm per-user pricing and payment processing fees before signing.
Do I need separate software for trust accounting?
It depends on your platform. Tools with built-in trust accounting handle IOLTA accounts and reconciliation internally. General tools like QuickBooks and Xero need a separate trust ledger or a legal add-on. Your state bar sets the recordkeeping rules, so confirm compliance before choosing.
Can I migrate from QuickBooks to a legal platform?
Yes. Most legal platforms offer migration help, and LeanLaw works directly on QuickBooks Online if you prefer to keep it. Plan the migration around month-end, reconcile trust accounts before moving, and run both systems in parallel for one billing cycle to catch errors.
