The Dollar-to-Signed-Case Gap

The average personal injury firm spends between $30K and $80K a month on media. Ask the managing partner where that money goes and they’ll name channels: TV, Google, social. Ask which channel produced last month’s signed cases and the room gets quiet.

That silence is the gap. It’s not a data problem, not yet. It’s a measurement discipline problem. Firms buy reach and hope attribution sorts itself out at intake. It doesn’t.

What $50K Buys When You Can’t Track It

The $50K figure is illustrative, projected from panel data directionally confirmed across markets we monitor. It represents the median monthly spend in mid-market personal injury where the gap is widest: enough budget to run multiple channels simultaneously, not enough infrastructure to know which one closed the case.

At that spend level, firms are running paid search and some form of broadcast or CTV at the same time. When a call comes in, the intake team asks “how did you hear about us?” The answer is almost always “TV” or “online” or “I don’t remember.” That response goes nowhere useful.

The attribution gap isn’t a new problem. What’s changed is cost. When a signed case is worth $40K to $200K in contingency fee value, flying blind on a $50K monthly budget means even a 10% misallocation is a measurable business mistake. It compounds every month.

Where the Leakage Happens

The leak isn’t random. It concentrates in three places.

Channel overlap at the top of the funnel. A prospect sees a CTV spot Tuesday night, searches the firm’s name Wednesday morning, and calls Wednesday afternoon. The intake system credits search. The CTV spend looks like it generated nothing. The firm cuts streaming and doubles down on Google. Now they’re buying the bottom of a funnel they’re no longer filling.

Intake as the only measurement point. Most firms treat the intake call as the first trackable event. Everything upstream is dark. Search impression data, view-through conversion windows, call source tracking by session, none of it feeds back into the attribution model. Intake is the last mile, not the whole race.

No line between media spend and signed case volume. Marketing runs the spend. Operations runs intake. Finance counts signed cases. These three functions rarely share a data model. Marketing reports impressions and calls. Operations reports signed rate. Finance reports revenue. The thread that connects media dollar to signed case doesn’t exist in any single system.

The Method We’ll Use to Confirm It

This study is in preview. The directional thesis is supported by panel data we’re collecting across 40+ firm-level accounts, but the full quantified proof isn’t published yet.

The measurement approach tracks three inputs against one output.

Inputs: channel-level spend broken out by week, call and form volume by tracked source, and intake conversion rate by lead source. Output: signed cases matched back to originating media event within a 30-day attribution window.

We’re validating the window length and source-matching methodology before publishing final numbers. The 30-day window reflects the median time from first brand exposure to signed retainer in mass-tort and personal injury, based on intake timing data across the panel.

When we publish the live version, we’ll report the dollar-per-signed-case by channel, the misattribution rate (the share of signed cases where the credited source is demonstrably wrong), and the budget reallocation opportunity in dollar terms.

Why This Matters to a CMO or CFO

The threshold question isn’t “is my CPA reasonable?” It’s “do I know which channel produced which case?” If the answer is no, the CPA figure is fiction. It’s total spend divided by total signed cases, averaged across every channel regardless of contribution.

That number hides two things. It hides the channels that are working well and being under-funded. It hides the channels eating budget without producing signings. Both problems are expensive.

A firm running $50K a month with no attribution model is making portfolio decisions in the dark. They’re not allocating. They’re guessing with a large number.

What “Confirmed Attribution” Changes

When firms build the measurement infrastructure, the CPA by channel tends to diverge sharply from the blended average. Paid search on branded terms often shows a low CPA because it captures demand that CTV created. CTV looks expensive until you remove the demand it generated from the search CPA calculation. The channels are interdependent. The attribution model has to reflect that or it’s producing bad signals.

The fix isn’t complicated. Call tracking by source, session-level UTMs that survive intake, a signed-case field that traces back to originating campaign. Most CRMs can hold this data. The gap isn’t technical. It’s that nobody’s built the workflow connecting media to case management to finance.

What’s Coming

The live version of this study will publish with firm-level panel data, channel-specific misattribution rates, and the dollar-value of the reallocation opportunity by market. Preview findings already point in a consistent direction: firms that track attribution at the signed-case level spend less per case, not because they found cheaper traffic, but because they stopped funding the channels that weren’t producing.

That’s the gap. We’re going to measure it.
