The short version

Legal billing software for small firms, compared on published prices: billing-first tools, QuickBooks sync, LEDES and trust accounting, and who each one suits.

Legal billing software for small firms splits into two camps: full practice management suites that include billing, and billing-first tools that do time, invoices and payments without running the whole practice. This guide covers the second camp, for firms that already have a way to manage matters and documents, or that keep their books in QuickBooks and want billing that fits around it.

Prices are from each vendor’s own pricing page, checked October 24, 2026. For full suites, see our legal software guide and our small law firms page.

Why Billing Still Drives the Choice

Most small firms still bill by the hour. Data from 8am, covered in our piece on how the billable hour still rules at small and midsize firms, shows how central hourly work remains. That makes time capture, rate handling and invoice clarity the core of a billing tool, ahead of extras.

The professional rules also shape billing. ABA Model Rule 1.5 says the basis or rate of a fee and the expenses a client will pay should be communicated, preferably in writing, before or within a reasonable time after the work begins, and that contingent fee agreements must be in a signed writing. Billing software does not satisfy those duties on its own, but clear rate tables and itemized invoices make it easier to show the client what was agreed. That is a description of the model rule, not advice on any state’s version.

Billing-First Tools and Their Prices

Bill4Time publishes every tier. Its pricing page lists Time and Billing at $39 per user per month billed annually, which includes invoicing, payment processing and a QuickBooks integration. Its legal plans are Legal Pro at $59, which adds trust accounting, a conflict checker, contingency billing and LEDES export, and Legal Enterprise at $89. It says yearly billing saves up to 25% and offers a 14-day free trial with no credit card.

LeanLaw is built on QuickBooks Online. Its pricing page lists Core at $55 per user per month, with time and expense tracking, e-payments, invoices, trust accounting and two-way QuickBooks Online sync, and Pro at $75, which adds custom invoice templates, LEDES files and matter-based accounting. A contingency plan is priced on request. It offers a seven-day free trial.

TimeSolv’s pricing page lists QuickBooks, Xero and LawPay integrations, trust accounting, LEDES and split billing, and a 10-day free trial, with 25% off the first year on annual plans at the time we checked. We could not read its base plan prices from the page, so ask for a written quote.

QuickBooks, LEDES and Time Capture

Firms that keep their books in QuickBooks usually want billing to feed it rather than replace it. The tools differ in how. LeanLaw describes itself as running natively on QuickBooks Online with two-way sync. Bill4Time and TimeSolv list QuickBooks integrations among their features. Ask each vendor which version of QuickBooks it supports, what syncs in each direction, and how trust transactions are handled, since ABA Model Rule 1.15 requires client funds to be kept separate from the lawyer’s own.

Also ask about LEDES. Firms that bill insurers or corporate legal departments often need LEDES invoice files. Bill4Time includes LEDES export from Legal Pro and LeanLaw from Pro, so the cheapest tier may not be enough.

Time capture is the next fight. Vendors are building tools that log time automatically, including time lawyers spend working in AI, as we reported on Legora and Laurel. None of the billing-first tools above leads with AI on its pricing page. For small firms, the practical question is whether captured time lands cleanly on an invoice the client understands.

Common Questions

What is the cheapest legal billing software?

Of the tools here, Bill4Time’s Time and Billing plan at $39 per user per month billed annually is the lowest published price. Its legal-specific features start at $59.

What legal billing software works with QuickBooks?

LeanLaw runs on QuickBooks Online with two-way sync. Bill4Time and TimeSolv list QuickBooks integrations.

Is there free legal billing software?

None of the three tools here has a free plan. All offer free trials of 7 to 14 days.

Do I need LEDES billing?

Only if a client, insurer or legal department requires LEDES files. Check before choosing a tier.

The Verdict

Real. Billing-first tools give small firms a cheaper path than a full suite when matter management is already covered, and two of the three here publish complete prices. The catch is that LEDES, trust accounting and contingency features usually sit one tier up.
