Law firms that do contingency work often skip time tracking because there is no client invoice. That creates a data gap. Contingency work drives a large share of many practices. You do the work. You track the outcome. What you often do not track is the time.
When the client does not pay by the hour, there is no invoice to force time entry. So time on contingency cases goes unlogged. That leaves effective hourly rate and matter economics as guesswork. You know what you recovered. You do not know what each matter really cost in hours, or what you effectively earned per hour.
Shadow billing fixes that. It means recording time on contingency matters for internal use only. No client bill. The data stays in the firm so you can measure cost, effective rate, and portfolio mix. The problem is not the idea. The problem is getting the time into the system without adding more work for anyone.
Why Shadow Billing Matters
Shadow billing is time you record on contingency (or other non-hourly) matters purely for your own metrics. You never send that time to the client. You use it to answer questions that matter for the firm.
None of that works without actual time data. Shadow billing is the practice of capturing that data for internal use. The bottleneck is capture itself.
Why Time Tracking on Contingency Cases Gets Skipped
On hourly work, the client invoice creates a deadline. Time has to be entered so the bill can go out. On contingency work, there is no such deadline. No one is waiting for a timesheet. So time entry becomes optional, and optional loses.
Manual entry on contingency matters competes with billable work. Fee earners are asked to log time "just for the firm." There is no immediate payoff for them. Timers and end-of-day logging on contingency cases are the first to drop when the day gets busy. The result is missing data or spotty data. Some matters get logged, others do not. Effective rate and matter cost stay incomplete or wrong.
That is not a discipline problem. It is a structural one. The incentive to log (client bill) is absent. The cost of logging (manual entry) is real. So the firm asks for shadow billing but rarely gets it in full.
The Workflow Problem
Asking lawyers to log contingency time the same way they log billable time does not work. They already have timers and timesheets for hourly matters. Adding another layer for "internal only" contingency time means more starts and stops, more forms, more end-of-day reconstruction. It feels like overhead. It gets deprioritized.
Pushing harder does not fix the structural issue. The only fix is to capture the time without adding steps to the lawyer's day.
That means automatic capture: the same work that happens in email, calls, and meetings automatically gets turned into draft time entries in the background. The lawyer reviews and approves. No new routine, no timers for contingency matters. The data appears because the system captures it, not because someone remembered to log it.
How Automatic Capture Solves It
Automatic capture uses the same pipeline you would use for billable matters. The tool connects to the channels where work happens: email (Gmail, Outlook), Zoom, Teams, phone, messaging. It sees activity, matches it to matters (including contingency matters in your PMS), and creates draft time entries with duration and narrative. The lawyer sees a list of drafts, approves or edits, and the entries sync to the practice management system.
For contingency matters, those entries are marked as non-billable or internal. They never become a client invoice. They do become hours per matter, cost at your standard rate, and the basis for effective hourly rate when the matter resolves. The workflow for the lawyer does not change. They work as they always do. The only difference is that time is captured in the background and turned into entries they can review in a few minutes instead of reconstructing from memory.
So shadow billing stops depending on "remember to log." It depends on "review what was captured." That is a different problem, and one that scales.
What You Get
With time captured on contingency matters, you get:
Example: A matter closes with a $120,000 recovery. Without logged time, you do not know if that came from 40 hours or 200. With 80 hours captured at a $300 standard rate, internal cost is $24,000 and effective hourly rate is $1,500. That number informs how you take on and staff the next similar matter.
Lawgbook: Automatic Time Entries
Lawgbook is built to capture communications and other activity and turn them into time entries. It connects to email (Gmail, Outlook), Zoom, Teams, phone systems (e.g. RingCentral, VXT), and messaging (e.g. WhatsApp). It matches activity to matters using participants and content, then generates draft entries with duration, narrative, and rate. You review and approve; approved entries sync to your practice management system (e.g. Clio) and into your Clio timekeeping workflow.
For contingency cases, you use the same capture and matter matching. Contingency matters live in your PMS like any other. You configure matter-level or firm-level rules so that time on those matters is treated as non-billable or internal. Entries still flow into the PMS so you have one place for matter hours and matter data. They simply do not appear on a client invoice. Lawgbook's existing billable rules engine supports exactly that: firm- and matter-specific rules for what is billable versus administrative (non-billable). So you get full shadow billing without changing how anyone works, only how time is captured.
Before and After
| Without shadow billing | With automatic capture | |
|---|---|---|
| Time on contingency matters | Not logged or spotty | Captured and matched to matters |
| Effective hourly rate | Unknown or wrong | Recovery divided by actual hours |
| Matter cost | Guesswork | Hours times standard rate |
| Workflow for lawyers | Manual entry or nothing | Review and approve drafts only |
| Data quality | Missing or incomplete | Consistent and contemporaneous |
The shift is from "we should log contingency time" to "we have it." Automatic capture makes that shift possible without disrupting how anyone works.
What to Do Next
If your firm does contingency work and you want effective hourly rate and matter economics without manual time entry, the next step is to see how automatic time tracking works for contingency matters. Lawgbook integrates with Clio and other practice management systems. You can run it on a subset of matters (e.g. contingency only) or firm-wide. Time is captured in the background; you configure which matters are billable and which are shadow billing. The goal is simple: full time data on every matter, including contingency, so you can measure what each case really costs and what it effectively pays per hour.
