Most law firms don’t have a revenue problem — they have a leakage problem. Work happens that never gets recorded. Recorded work never becomes an invoice. Invoices go out and nobody follows them. None of it shows up in QuickBooks, because QuickBooks only sees what survives the journey.

This calculator estimates the three leaks using your own numbers. It deliberately understates: it assumes half your aged receivables eventually get paid, and it counts only fee-earners. It isn’t an audit — it’s a torch. In our experience, the firms that measure these numbers are the ones that fix them; the real figure usually surfaces only after a firm starts tracking, which is rather the point.

If the number surprised you, the useful next question is not “is it exact?” but “where is it coming from?” The three usual answers — unrecorded work, unbilled work, and uncollected invoices — are exactly the gaps between the tools most firms run on. That’s what a connected system closes. Read: Why Excel + QuickBooks isn’t enough →

Frequently asked questions

Is this figure accurate?

It’s a conservative estimate built from your own inputs. The exact figure requires tracking — which most firms can’t do until they have a system. Treat it as a floor, not a ceiling.

What counts as revenue leakage?

Any value the firm earned but never banked: hours worked but unrecorded, work recorded but never invoiced, and invoices that age past collection.

How does SmartCase stop it?

By connecting the journey: time is captured as work happens, invoices generate from captured time, and receivables are tracked and chased systematically — with partners seeing the whole picture in one report.
