LeanLaw vs. ProLaw: At a Glance
| LeanLaw | ProLaw | |
|---|---|---|
| Books | One source of truth: QuickBooks Online | Two sets of books — ProLaw’s proprietary accounting plus your accountant’s QuickBooks |
| Accounting | Native QuickBooks Online | Proprietary accounting module |
| Architecture | Cloud-native, access anywhere | Legacy all-in-one practice-management system |
| Reporting | Real-time WIP, billed & collected | WIP / billed / collected via a manual, multi-step process |
| Accountant access | Free — they work directly in QuickBooks | Forced to learn ProLaw’s system |
| Best fit | Firms that want modern billing powered by QuickBooks | Firms committed to a legacy all-in-one platform |
ProLaw forces your firm to maintain two sets of books. LeanLaw keeps a single source of truth in QuickBooks Online — the system your accountant already uses — so billing and accounting finally agree.
Sound Familiar? You’re Not Alone.
“You’re Wrestling with Two Sets of Books” ProLaw combines billing and its own proprietary accounting, but your accountant lives in QuickBooks. This forces your firm to maintain two separate financial systems, leading to hours of manual work to reconcile and sync them. “You’re Paying for a System You Don’t Fully Use” ProLaw is a comprehensive practice management solution, but your firm is seeking a financially focused timekeeping and billing tool. You’re paying for a bloated, all-in-one platform when you just need your financials to work seamlessly. “It Feels Like We’re Flying Blind” Getting simple financial reports like WIP, Billed, or Collected is a manual, multi-step process. You’re making critical business decisions based on gut feelings instead of real-time, data-driven insights. The truth is: ProLaw is a legacy system that forces you into its proprietary accounting module, creating more inefficiency. You just need a modern billing platform powered by QuickBooks. Why pay for a system that creates more manual work?

“Back office couldn’t extract KPIs, request evergreen retainers or get real-time reports on their data. They thought they wanted a practice management solution. (ha!)”
Karyn Anderson — Total Sum Accounting
“The lawyers wouldn’t enter time until the end of the month, and it had to be coded manually. And the software was not connected to their bank, so invoices were sent by mail.”
Jennifer Wells — Business Manager, Beard St. Clair Gaffney Law Firm
“Tracking payments to specific matters was a nightmare — not to mention they were still sending paper invoices and receiving paper checks.”
Amanda Coughlan — Billing Coordinator, Zahn Law Group
