Accounting software for lawyers has to do one thing general bookkeeping tools aren't built for: keep client money held in trust separate from the firm's own money, with records that reconcile. Most options are legal practice management suites with trust accounting built in, or time and billing tools that add it. Check what each vendor says about trust accounting first.
If you only take one thing from this page, make it this: look for trust accounting first and everything else second. Your firm's operating account can live in almost any accounting package, but money you hold for clients needs its own ledgers, and that's the part a general tool won't track for you.
The ten tools below are listed alphabetically and in no particular order. Every description comes from the vendor's own website, read as of Oct 2026, and I've kept to what each page says about accounting, trust funds, billing and payments. For general small business options outside the legal world, see my guide to accounting software tools.
Legal accounting tools side by side
I checked the free plan column on each vendor's own website, as of Oct 2026. Yes means the page names a free plan, a free version or an open source edition. Trial only means it names a time-limited free trial. Not stated means the page I read named neither, so check the vendor's own site before you sign up.

Ten accounting tools for law firms
AbacusLaw
Best for: Firms of any size that want all-in-one legal practice management with accounting built in, as its listing on the Amicus Attorney site describes it.
Bill4Time
Best for: Lawyers who mainly need billable hours logged from desktop or mobile, custom rates and billing codes, a client portal and secure online payments.
Clio
Best for: Firms already on a wider legal platform with legal AI, audit trails and connections to 300+ apps, wanting legal accounting in the same place.
CosmoLex
Best for: Practices that want practice management, billing, trust accounting and firm accounting in one platform rather than a separate bookkeeping package.
Filevine
Best for: Teams whose priority is legal AI agents and legal research across every matter; its page leads with its LOIS platform rather than accounting.
LawPay
Best for: Attorneys taking card payments from clients who want IOLTA compliance and next day payments as a payments layer beside their accounting.
LEAP
Best for: Practices that want legal accounting, invoicing, retainer funds and trust accounting the vendor says helps maintain compliance with IOLTA and state bar rules.
Smokeball
Best for: Solo, small and medium firms that want admin, billing and paperwork handled in one system, with trust accounting listed among its billing tools.
TimeSolv
Best for: Billing-led firms that want time tracking and invoicing with built-in trust accounting, automated three-way reconciliations and trust reports.
Zola Suite
Best for: Teams that want billing, accounting and payments inside cloud practice management, with workflows, permissions and reporting shaped around how the firm works.
Trust accounting is the first test
The most specific promise on any of these pages comes from TimeSolv. It says it will "track client funds separately, automate three-way reconciliations, and generate trust reports that meet bar requirements." A three-way reconciliation matches three records against each other: the bank statement for the trust account, the trust account ledger, and the ledger for each client. If those three don't agree, something's wrong, and you want to find out at the end of the month, not when someone asks.
Want AI doing the heavy lifting in your marketing?
I build the systems that handle the boring 80 percent, so you get your week back. Done properly, with the human kept in.
LEAP makes a similar point, saying its trust accounting helps you "maintain compliance with IOLTA and state bar rules". That's the vendor's claim, not a guarantee, so ask any supplier to show you a reconciliation report on a demo account before you commit.
Four kinds of legal accounting tool
- Practice management with accounting built in. One system for matters, billing, trust and the firm's own books. CosmoLex calls itself "the only fully built-in practice management and firm accounting platform for law firms". That word "only" is the vendor's own, and another tool on this list is described as all-in-one legal practice management and accounting, so compare both.
- Practice management with trust accounting in billing. Smokeball lists trust accounting next to invoicing and payments in its billing tools, so check whether you'd still need separate software for the firm's operating books.
- Time and billing first. Tools that started with billable hours and invoices, then added trust accounting or accounting features. Bill4Time lists accounting among its features, alongside time tracking, invoicing and online payments.
- A payments layer. LawPay is legal payment software. Its page talks about IOLTA compliance and next day payments, so it sits beside your accounting rather than replacing it.
One tool here leans the other way. Filevine's page leads with legal AI and legal research, not accounting, so check its accounting depth on a demo. Clio's legal accounting page also sits inside a much wider platform with legal AI and enterprise controls, so expect accounting to be one part of a bigger system.
Names that have moved
Two of the ten now sit on other brands' websites, which is worth knowing before you go looking for them. The Zola Suite details here come from CARET Legal's own site, which lists billing, accounting and payments in its cloud practice management menu. The AbacusLaw listing sits on the Amicus Attorney site, under the CARET name, described as all-in-one legal practice management and accounting.
Questions to put to any legal accounting vendor
- Does it reconcile the trust account three ways, and can it produce that report on demand?
- Does it keep a separate ledger for each client, and stop you drawing more from a client's funds than they hold?
- Will it run the firm's operating books too, or will you still need a general accounting package beside it?
- How do card and online payments land: in the trust account, the operating account, or either, depending on the invoice?
- Who at your firm will reconcile each month, and can your accountant get read-only access to check it?
Do you make accounting, billing or trust accounting software for law firms? Tool makers can ask to be considered for a featured place on this list.
My plain advice for law firms choosing accounting software
Decide where your firm's own books will live before you look at features. If you want one system for everything, shortlist the practice management suites with firm accounting built in. If you already have an accounting package you're happy with, a time and billing tool with trust accounting may be enough. Either way, book a demo and ask to see a three-way reconciliation, because that's the report that'll matter most when it counts.
And bring your accountant into the decision early. They'll know which exports they need, and it's far easier to set the chart of accounts up right on day one. If you're also weighing what else to automate in the back office, my piece on what law firms can safely automate is a useful next read.

Frequently asked questions
What accounting software do lawyers use?
Most firms use legal practice management software with accounting or trust accounting built in, or a legal time and billing tool, often alongside a general accounting package for the firm's operating account.
What is trust accounting for lawyers?
It's the record keeping for money a firm holds on behalf of clients, such as retainers. That money has to be tracked client by client and kept apart from the firm's own funds.
What is a three-way reconciliation?
It's a check that the trust account bank statement, the trust account ledger and the total of all client ledgers agree. Some legal billing tools say they automate it.
Can lawyers use general accounting software?
For the firm's operating account, yes. For client money held in trust, look for software that keeps client ledgers and reconciles them, and check the rules that apply to your firm with your accountant.
Can these tools take card payments from clients?
Several list online or card payments, and one is a legal payments tool in its own right. Check that payments can be directed to the right account, trust or operating, before you switch them on.
