LeanLaw
#23 of 39Legal billing that syncs with QuickBooks Online for small law firms
LeanLaw is the obvious choice if your firm runs on QuickBooks Online and you need legal-specific billing on top. If you don't use QBO, there's no reason to choose this over CosmoLex, which handles accounting natively.
Best for
Solo attorneys and small firms that love QuickBooks and want legal billing that integrates deeply with it rather than replacing it.
Company size
1-10 attorneys
What it costs
| Plan | Price | Users |
|---|---|---|
| Core | $40 /mo per user | Custom |
| Complete | $70 /mo per user | Custom |
What's good
- Deepest QuickBooks Online integration in the legal space — two-way sync means your accountant works in QBO while you work in LeanLaw
- Trust/IOLTA accounting that flows directly into QBO eliminates double-entry between systems
- G2 rating of 4.7 shows strong satisfaction among users
- Starting at $40/user for billing is competitive, and includes trust accounting
What's not
- Requires QuickBooks Online subscription on top of LeanLaw — if you don't use QBO, this tool has no advantage
- No conflict checks, intake forms, eSignature, or document automation
- Limited as a full practice management tool — it's primarily billing with some PM bolted on
- No email management integration
