Your Team Works Hard. Where Does the Revenue Go?
Revenue leakage is the gap between what your firm earns and what it actually collects. It's not fraud. It's not negligence. It's the dozens of small friction points that erode revenue at every stage of the billing cycle — and they compound silently.
Most managing partners are aware something is wrong — they just don't have a number. This audit gives you the number.
- Billable time logged an hour late is often not logged at all
- Invoices sitting in draft for 12 days extend every collection cycle
- Write-downs are a habit, not a policy — and they add up to 10–15% of revenue
- A 90% realization rate sounds strong — until you multiply the 10% gap by 50 attorneys
- Every dollar leaked is money already earned by someone at your firm

Where Law Firms Lose Revenue — and How LeanLaw Closes Each Gap
Every firm leaks revenue through the same four channels. The difference between high-performing firms and the rest is whether they have systems to close them.
The Hours That Never Get Captured
Research shows attorneys underreport 1–2 hours of billable work per day. Phone calls, quick emails, and research performed away from the desk go unlogged. At any billing rate, this is the single largest source of revenue leakage.

Discounting Work You Already Did
Editing invoices downward before sending — to avoid client friction, round numbers, or cover for non-standard time — erases real revenue. The average firm writes down 8–12% of all invoiced time.

Every Day You Wait Costs Money
Most firms take 10–14 days to generate an invoice after work is performed. That delay extends your cash cycle, increases the risk of non-payment, and carries an implicit opportunity cost at every billing rate.

The Gap Between What You Bill and What You Collect
Discounts, no-charge time, and uncollected balances erode your effective rate below your standard rate. A realization rate below 90% is a signal that pricing, billing, or collection workflows need attention.

Revenue Leakage Audit — Frequently Asked Questions
Questions about the calculator, the methodology, and how LeanLaw closes each leakage gap.
What is revenue leakage in a law firm?
Revenue leakage is the gap between what your firm earns and what it actually collects. It shows up as unbilled billable time, write-downs, slow invoicing, and realization shortfalls. The average firm leaks $61K per attorney each year — money already earned but never captured or collected.
How does this calculator estimate leakage?
The calculator uses your firm's number of attorneys, blended hourly rate, and billed hours per attorney per year to estimate potential revenue. It then applies three leakage percentages you control: time capture loss (unrecorded activities), pre-bill edit rate (reductions during invoice preparation), and write-down rate (post-invoice reductions or uncollected bills). Each percentage is applied to potential revenue per attorney, the three results are summed, and then multiplied by your attorney count. Totals update live as you adjust each input.
How does LeanLaw reduce unbilled time?
LeanLaw's mobile time capture lets attorneys log time from anywhere — phone, desktop, tablet — at the moment work happens. Built-in prompts and matter-linked timers ensure nothing slips through the cracks. Firms typically recover 1–2 billable hours per attorney per day they were previously missing.
How fast can LeanLaw get invoices out?
LeanLaw customers generate invoices within 2–3 days of work completed, compared to the 10–12 day industry average. Automated billing queues, one-click approval workflows, and direct QuickBooks Online integration eliminate the manual steps that create delay.
How much faster do firms collect with LeanLaw?
LeanLaw firms collect invoices 70% faster on average, driven by online e-payment links embedded in every invoice, automated reminder sequences, and a real-time outstanding AR dashboard so nothing ages unseen.
