Switch from Advantage Law
Switch from AdvantageLaw to LeanLaw — billing on QuickBooks Online.
AdvantageLaw is long-standing Windows desktop practice-management software. LeanLaw is cloud legal billing built for QuickBooks Online — so your firm’s money work lives with the books, not in a separate desktop silo.

What LeanLaw will and will not do
Expect a hard data path — LeanLaw does not retrieve AdvantageLaw for you
Getting usable data out of AdvantageLaw typically means building custom reports inside AdvantageLaw. That work belongs to your firm or a specialist you hire — it is not a standard LeanLaw migration service. LeanLaw onboarding can still help you configure QuickBooks Online and train your team once you are ready to bill in LeanLaw.
Side by side
AdvantageLaw and LeanLaw, side by side
AdvantageLaw details below reflect common third-party directory descriptions of a Windows desktop practice-management suite. Confirm current AdvantageLaw packaging with the vendor.
LeanLaw is legal billing, time, and trust workflows on QuickBooks Online — not a full practice-management replacement for every AdvantageLaw module. Keep AdvantageLaw (or another archive) if you need historical invoices, documents, or features LeanLaw does not cover. Confirm the gap in a demo before you buy.
| Feature | AdvantageLaw | LeanLaw |
|---|---|---|
| Access model | Primarily Windows desktop practice-management software (directory listings) | Cloud software — use from the browser with mobile apps available |
| QuickBooks Online | We could not confirm a native QuickBooks Online sync from public listings. Confirm current QuickBooks options with AdvantageLaw. | Built for QuickBooks Online — invoices, payments, and trust activity sync to QBO |
| Billing & books | All-in-one desktop suite (time, billing, trust, GL) per vendor descriptions | Legal billing that posts into your QuickBooks Online books |
| Trust accounting | Trust accounting included in the suite (vendor/directory descriptions) | Matter-level trust ledgers and trust reports that support three-way reconciliation in QuickBooks Online |
| Updates & support | Desktop practice-management software; current license and support terms should be confirmed with AdvantageLaw | Subscription includes product updates; support included with your plan |
| Moving your data | No standard data export — retrieving data typically means building custom reports inside AdvantageLaw | LeanLaw does not pull AdvantageLaw data for you. If your firm builds custom reports and brings files over, we can advise on LeanLaw setup — that retrieval work is yours (or a specialist you hire), not a standard LeanLaw service |

A practical switch path
How a switch actually works
- 1
Discovery & go-live plan
We learn your matters, billing workflow, and QBO setup — and we’re clear up front that AdvantageLaw data retrieval (usually custom reports) is your firm’s responsibility, not something LeanLaw normally runs for you.
- 2
Your custom reports (if any)
If you need opening balances or lists in LeanLaw, your firm builds custom reports in AdvantageLaw (or hires someone to). LeanLaw does not normally do that retrieval. We do not certify completeness of anything you bring over.
- 3
QBO setup, training & first invoices
We help connect LeanLaw to your QuickBooks Online account and train the people who will bill. Many firms start LeanLaw fresh for new work and keep AdvantageLaw as a read-only archive. First-invoice timing depends on QBO setup and how fast you cut over — not on LeanLaw extracting AdvantageLaw.
From firms using LeanLaw
What customers say about the QBO-connected workflow
“Tracking payments to specific matters was a nightmare before LeanLaw. Now everything syncs to QuickBooks automatically. We see invoices paid 70% faster.”
“We've used LeanLaw for a year and a half and we're able to invoice our clients within two to three days, versus 10 or 12 — quickly and electronically, and they pay us faster, which increases our cash flow.”
“As a bookkeeper in the legal industry, I appreciate how well LeanLaw integrates with QuickBooks Online. It is simple to use and makes keeping up with law-firm finances far easier.”
FAQ
Switching from AdvantageLaw — straight answers
Why do firms look at LeanLaw when they use AdvantageLaw?
AdvantageLaw is long-standing Windows desktop practice-management software used by law firms for billing, time, trust, and accounting. Firms that adopt QuickBooks Online often want legal billing that posts into that QBO ledger rather than keeping billing in a separate desktop application. LeanLaw is built for that QBO-connected workflow.
Does LeanLaw extract data from AdvantageLaw for me?
No. LeanLaw does not log into AdvantageLaw or retrieve data for you. Getting data out of AdvantageLaw typically means your firm (or someone you hire) builds custom reports inside AdvantageLaw — and that retrieval is not something LeanLaw normally does for customers. If you independently produce files we can work with, onboarding can help you get set up in LeanLaw.
Will all of my historical AdvantageLaw billing history appear in LeanLaw?
Not automatically — and often not at all without significant effort on your side. AdvantageLaw does not offer a simple full-history handoff into LeanLaw. Any data you bring over usually comes from custom reports you create (or pay someone else to create). LeanLaw does not promise a complete historical archive in LeanLaw. Expect to keep AdvantageLaw (or another archive) for history unless you choose to rebuild what you need.
Does LeanLaw require QuickBooks Online?
Yes. LeanLaw is built to work with QuickBooks Online, so an active QBO subscription is required. Many firms already keep books in QuickBooks alongside desktop practice software — LeanLaw is designed to connect legal billing to that QBO ledger.
Does LeanLaw automate three-way trust reconciliation?
LeanLaw maintains matter-level trust ledgers and provides trust reports that support the three-way reconciliation process (bank, books, and client ledgers). Per LeanLaw’s support documentation, the formal three-way reconciliation is completed primarily in QuickBooks Online using LeanLaw trust data as one of the three components — not as a fully hands-off automated black box.
Is customer support included?
Yes. Support is included with LeanLaw plans. Response times vary by channel and queue; we do not guarantee a specific average on this page.
