I talk to plaintiff firms every week about their mass arbitration campaigns. Almost every one of them can tell me their cost-per-lead to the dollar. Google Ads CPC, Facebook CPM, cost per form fill, cost per call. They have dashboards. They have weekly reports. They have opinions.

Ask them what happens between "lead hits the CRM" and "claimant signs the retainer," and you get a different energy. Vague answers. Approximations. "Our intake team handles it."

That gap is where firms lose more money than they spend on media. And on a 5,000-claimant mass arb matter, the math gets ugly fast.

The Number Nobody Tracks

Here's a scenario I see constantly. A firm runs a paid acquisition campaign for an arb-eligible consumer matter. The media agency reports a $200 cost per lead. The firm greenlights more spend based on that number.

But only 20% of those leads actually sign a retainer and complete the documents needed to file. The real cost per signed claimant is $1,000, not $200. And that's before you account for the intake team's time, the follow-up calls, the re-sends, and the claimants who ghost after the first text.

If you're running a matter where your expected fee per resolved claimant is $3,500 to $4,500, a $1,000 CPA might still work. But most firms don't know they're at $1,000. They think they're at $200. That's the kind of modeling error that turns a profitable campaign into a break-even one, and you won't see it until disbursement.

Where the Conversion Funnel Actually Breaks

I've watched enough campaigns to see patterns in where leads die. It's usually one of three places:

  1. Speed to first contact. Legal lead-gen data consistently shows that contacting a lead within five minutes of submission produces conversion rates three to five times higher than waiting an hour. Most plaintiff firms don't have intake infrastructure that responds in five minutes. They have a paralegal who checks the CRM twice a day. By the time someone calls the claimant back, the claimant has forgotten they filled out a form, or a competing firm already reached them.
  2. The signing step. A lead is interested. They're on the phone. They're ready to move forward. Then you email them a PDF retainer and tell them to print, sign, scan, and return it. Or you send them to a DocuSign link that loads slowly on mobile and requires an account. Every friction point between "yes, I want in" and "signature captured" is a place where a warm lead turns cold. On a mass arb matter with thousands of claimants, even a 10% drop at the signing step costs you hundreds of signed claimants.
  3. Post-sign document collection. The retainer is signed, but now you need ID verification, a declaration, maybe proof of purchase or account ownership. Each additional step without a frictionless workflow is another dropout. The claimant meant well. They just didn't feel like hunting for a screenshot of their account page at 10 p.m. on a Tuesday.

None of these are media problems. They're all intake and infrastructure problems. And they all inflate your true CPA without showing up in your ad dashboard.

The Math on a 5,000-Claimant Campaign

Let's put numbers on it. Say you're acquiring claimants for an arb-eligible consumer matter. Your media agency delivers 10,000 leads at $150 per lead. That's $1.5 million in ad spend.

At a 50% lead-to-signed-claimant rate, you get 5,000 signed claimants. Your CPA per signed claimant is $300. Solid.

At a 25% rate (which is closer to what I see when intake is slow and the signing flow has friction), you get 2,500 signed claimants. Your CPA per signed claimant is $600. You now need either twice the ad spend to hit your target claimant count, or you file with half the claimants you planned for.

The difference between those two scenarios is not a better ad creative or a cheaper keyword. It's whether your intake system contacts a lead in minutes or hours, whether your signing flow works natively on a phone screen without leaving the text thread, and whether your document collection happens in one session or three.

On a 5,000-claimant matter, improving your lead-to-signed rate from 25% to 40% saves you $562,500 in equivalent ad spend. That's not a rounding error. That's the margin on the matter.

Why Owning the Stack Changes the Intake Math

Most firms cobble together intake from three or four tools. A CRM here, an e-sign vendor there, a separate SMS platform, maybe a call center. Each handoff is a dropout point. Each vendor has its own login, its own latency, its own billing layer.

When we built the stack behind GroupSettle, the design started from this exact problem. Send It By Text puts native document signing, SMS, and email delivery into one flow. A claimant gets a text, taps a link, reads the retainer, signs it on their phone, uploads their ID, and they're done. No app downloads. No separate portals. No "check your email for the next step."

The AI super agent on top of that stack handles over 80% of inbound claimant questions on its own, which means the follow-up that used to require a paralegal checking a queue happens in real time, at 11 p.m., in Spanish, on the weekend. That's not a feature for a pitch deck. That's the difference between a lead who signs tonight and a lead who forgets by morning.

The conversion lift from removing friction at the signing step is not marginal. On campaigns we've administered, the difference between a multi-tool signing flow and a native one-tap flow shows up as double-digit percentage point improvements in lead-to-signed rates. At scale, that's hundreds of additional signed claimants on the same ad spend.

How to Audit Your Own Intake Funnel This Week

You don't need to change vendors to start. You need to measure what you're not measuring. Here's a five-step audit you can run on Monday:

  1. Pull your true speed-to-first-contact. Not the target. The actual median time between lead submission and first human or automated outreach. If it's over 15 minutes, you're losing claimants.
  2. Map every step from "lead in CRM" to "signed retainer in hand." Count the handoffs. Count the platforms. Count the places where a claimant has to do something on a different device or in a different session.
  3. Calculate your lead-to-signed rate. Total signed claimants divided by total leads acquired. If you don't have this number, that's the finding.
  4. Calculate your real CPA per signed claimant. Total acquisition cost (media plus intake labor plus vendor fees) divided by signed claimants. Compare it to the CPA your media agency reports.
  5. Identify your single biggest dropout point. Is it the gap between lead and first contact? The signing step? Post-sign document collection? Fix that one point before spending another dollar on ads.

Most firms who run this audit for the first time find that their real CPA is 1.5 to 3 times what they thought. That's not a failure. That's a discovery. And it means the cheapest way to acquire more claimants might not be more ad spend. It might be fixing what happens after the click.

The Takeaway

In mass arbitration, the firms that win are not always the ones with the biggest media budgets. They're the ones who convert the highest percentage of leads into signed, filed, completing claimants. Intake is not a back-office function. It's the highest-ROI investment in your entire acquisition funnel, and most firms treat it like plumbing.

Fix the plumbing. The CPA follows.
