Accounting for Law Firms in 2026: The Practical Guide

Client money sits in a separate account you are not allowed to touch, work in progress can be months of time, and disbursements are paid out long before they are billed. The compliance rules here are stricter than the accounting ones.

This is the bookkeeping side of that problem: the accounts to set up, the entries that go wrong, and what you can claim. If you are still choosing software, the round-up linked at the end compares the options.

The chart of accounts for a law firm

Start from these rather than the default template. The codes are illustrative; the separations are what matter, because each one answers a question you will be asked later.

1050 Client bank account
2150 Client ledger balances held
1150 Unbilled disbursements
1250 Work in progress by matter
4000 Professional fee income
4100 Recovered disbursements

The 3 entries a law firm gets wrong

Money received on account of costs

Client money until the bill is raised and the transfer is evidenced. Taking it as income early is both a revenue error and a regulatory breach.

A court fee paid for a client

An unbilled disbursement to recover, not a firm expense.

Time written off on a fixed-fee matter

Record it against the matter so the next fixed fee is quoted from reality.

What a law firm can claim

Deductibility follows the rule in your own jurisdiction, so this is a checklist to take to your accountant rather than an answer. For a law firm the cost lines to review first, and the record each one needs, are:

Whether each of those is deductible, and how much of it, is a rule your tax authority sets and changes. Keep the record either way; take the question to your accountant with the figures in front of you.

The reports to run every month

1. Client account kept and reconciled to the rules of your jurisdiction's regulator — review it monthly, not at year end.
2. Matter-level work in progress, disbursements and billing — review it monthly, not at year end.
3. Time recording that reaches the ledger, with write-offs visible per matter — review it monthly, not at year end.
4. Disbursements paid versus recovered, per matter — review it monthly, not at year end.

Frequently asked questions

What is the best accounting software for law firms?

There is no single best one; there is a best one for a shape of business. For a law firm, work down the criteria in the section above and stop at the first option that clears all of them — that list is short, usually two or three.

The criteria that eliminate most options fastest are: Client account kept and reconciled to the rules of your jurisdiction's regulator; Matter-level work in progress, disbursements and billing; Time recording that reaches the ledger, with write-offs visible per matter.

Give me a list of accounting software for law firms that offer the best security?

Ask for evidence rather than adjectives. The things worth checking, in order: an independent audit you can see (SOC 2 Type II or ISO 27001, with the report date), encryption in transit and at rest, enforced multi-factor authentication, role-based permissions fine enough that a bookkeeper cannot export your whole ledger, an immutable audit trail of who changed what, where your data is hosted and under which country's law, and a stated backup and recovery position.

Then ask the question the brochure will not answer: can you see, after the fact, who changed a figure and what it was before? For a law firm that audit trail is worth more than any single feature on the security page. A vendor who will send the audit report under NDA is telling you something; one who answers with the words "bank-grade security" is telling you something too.

Is there free accounting software for law firms?

There are free tiers, and they are real — but the limit is what matters, not the price. Find the cap before you move your books: how many documents or transactions a month, how many bank accounts, how many users, and whether the free tier includes the one thing you came for. HelloBooks has a free plan; /pricing lists what it covers today.

How much does accounting software for law firms cost?

Published prices move, and the figure that matters is the one including the module you actually need — inventory, payroll or multi-currency are often a tier up, so the headline price is rarely the price you pay. Price each shortlisted option at the tier that carries what you actually need, on the vendor's own page, on the day you decide.

How do I switch accounting software without losing my history?

Migrate on a period boundary and bring three things: opening trial balance, open customer and supplier balances, and your chart of accounts. Transaction history can usually stay in the old system as a read-only archive — attempting to re-import years of detail is where most migrations lose a week and a reconciliation.
