See What You're Missing
with Advantage Law.
AdvantageLaw is an on-premise desktop application that requires a local server, a paid support contract, and costly upgrades to stay current — while your bookkeeper still has to manually reconcile it with QuickBooks. LeanLaw is the cloud-native replacement with a native QuickBooks Online sync, automated trust accounting, and support that is actually free.
Cloud-Native, Not Cloud-Adapted
LeanLaw was built for the cloud from day one. Access your firm from anywhere — no VPN, no server, no IT headache.
Real-Time QuickBooks Sync
Every invoice, payment, and trust transaction posts to QuickBooks Online the moment it happens. No exports. No duplicates.
Automated Trust Accounting
Three-way reconciliation runs automatically. Reduce compliance risk without touching a separate ledger book.
Switching Is As Easy
As 1, 2, 3.
AdvantageLaw stores data in a proprietary on-premise format — but you do not have to figure out the export yourself. Our migration team handles the entire process: extracting your data from AdvantageLaw, importing it into LeanLaw, and validating every record before you flip the switch. Most firms are live and invoicing within 5 to 10 business days.
AdvantageLaw Discovery & Data Audit
We audit your AdvantageLaw instance — matters, clients, trust balances, custom bill codes, and any integrations — and build a migration plan around your specific data structure and go-live target date.
Proprietary Export, Import & Validation
Our specialists handle the AdvantageLaw data extraction, which requires navigating its proprietary on-premise format. We import every record into LeanLaw and run a validation pass so nothing is missing before you cut over.
QuickBooks Setup, Training & Go-Live
We connect LeanLaw to your QuickBooks Online account, configure your chart of accounts, and run live training for attorneys, billing staff, and bookkeepers. Most firms invoice their first LeanLaw bill within 5 to 10 business days of starting.

Everything You Need to Know
About Switching from Advantage Law.
Why are firms leaving AdvantageLaw for LeanLaw?
AdvantageLaw is an on-premise desktop application that requires a local server, an annual support contract sold separately, and costly version upgrades to stay current. Firms leave it because they can no longer work remotely without a VPN, their bookkeeper cannot see live data in QuickBooks, and every product improvement comes with an additional bill. LeanLaw is fully cloud-based, syncs to QuickBooks Online in real time, and includes every update in the subscription.
How does LeanLaw handle data export from AdvantageLaw?
AdvantageLaw stores data in a proprietary format that is not straightforward to export on your own. LeanLaw includes complimentary, guided data migration: our specialists know the AdvantageLaw data structure, handle the export process on your behalf, import the data into LeanLaw, and validate that every matter, client balance, and trust ledger entry has arrived correctly before you go live.
Will I lose any historical billing data when I switch?
No. Our migration specialists transfer your complete billing history — open matters, client records, trust balances, WIP, and accounts receivable — into LeanLaw before your go-live date. You will have full access to historical data inside LeanLaw from day one, so there are no gaps in your records.
Does LeanLaw require a separate QuickBooks subscription?
Yes, LeanLaw is built natively on QuickBooks Online, so an active QuickBooks Online subscription is required. Most firms switching from AdvantageLaw already use QuickBooks alongside it for general ledger work — LeanLaw replaces the manual journal entries between the two systems with a seamless, real-time, two-way sync.
How long does switching from AdvantageLaw to LeanLaw take?
Most firms complete their migration and send their first LeanLaw invoice within 5 to 10 business days of starting the process. The timeline depends on your data volume and how many custom bill codes or fee arrangements need to be recreated, but our migration team handles the heavy lifting so your attorneys and billing staff can keep working in AdvantageLaw until the cutover day.
Is customer support included in my LeanLaw subscription?
Yes, unlimited support via phone, email, or chat is included at no extra cost in every LeanLaw plan — unlike AdvantageLaw, which sells support as a separate annual contract. Our average response time is under 10 minutes.
