How Do You Scale a Personal Injury Firm to 100+ Signed Cases a Month?

When an injury firm stops growing, the cause is usually simple. It grew its ad spend faster than everything else.

It goes like this. A firm finds an ad channel that works and doubles the budget. Leads double too. But the intake team cannot keep up. Leads wait hours for a call. Fewer of them sign. The cost per case goes up, and the owner decides the channel "stopped working."

Usually the channel was fine. The firm ran out of room somewhere else.

So this guide treats growth as a math problem. We start at 100 signed cases a month and work backwards.

How many leads do you need for 100 signed cases?

Every injury lead goes through the same steps. It comes in. You reach the person. You find out if they have a case you want. Then they sign, or they do not.

Two numbers matter most:

• How many leads are good cases. In the firms we track, it is usually 10% to 40%.
• How many good cases sign. Usually 60% to 80%. Once a person with a real case talks to an attorney, they usually sign.

Look at the gap. At 40%, you need about 360 leads. At 10%, you need over 1,400. That gap matters more than the price of any click.

Here is a real example. This is one compensation firm we work with in Australia. We took a year of Facebook leads and shrank it down to 100:

Almost half the leads were never reached. But of the cases the firm wanted, it signed nearly two out of three. The firm lost most of its cases in the first two steps. That is normal, and it is why growth starts with intake.

How much is a signed injury case worth?

You cannot decide what to pay for a case until you know what it is worth.

Here is a starting point. The Insurance Information Institute says the average car accident injury claim in 2024 was $28,278. With a one-third fee, that is about $9,400 for the firm before costs.

But that is just an average. Many cases settle for less. A few settle for much more. So your mix of cases matters more than your count.

Firms that grow well know these numbers for their own cases: the average fee, how long cases take, and how many pay out within 12 to 24 months.

Big volume firms take lots of cases they know will never pay, because they have thousands of files. Smaller firms usually cannot do that. They need to be pickier.

How much can you pay for each signed case?

I use a simple rule. The profit from a case should be at least three times what it cost to get it. Profit here means the fee minus case costs and the cost of working the file.

The answer is different for each case type. If you run one budget for all of them, you overpay for small cases and underpay for big ones. Set a target for each case type.

And remember, cost per lead tells you very little. A $150 lead that turns into a good case 40% of the time is much cheaper than a $60 lead that works 10% of the time. Our guide to what a personal injury lead costs shows the math.

Why does cash flow stop injury firms from growing?

Because you pay for the case today and get paid a year or two later.

A firm spending $50,000 a month on ads puts $600,000 a year into cases that may not settle until next year. Add medical records, experts, filing fees and staff. A firm can be making good money on paper and still run out of cash.

Here is how to plan for it:

• Know how long cases take. Look at your last two years of settled cases. Work out the average time from signing to getting paid.
• Mix fast and slow cases. Quicker cases pay the bills while you wait on the big ones.
• Set up funding early. A line of credit is easier to get when things look good.
• Set your budget from your own numbers. Our marketing budget guide shows how.
• Grow in steps. Raise the budget. Wait until intake and staff can keep up. Then raise it again.

Which ad channel should you grow first?

One at a time. The biggest mistake is running five channels at once and doing them all badly. Get one working. Make it run without you watching it. Then add the next.

Our benchmark of the biggest injury firms in America shows how unevenly even the big firms use these channels.

How do you build an intake team that can handle 500 leads a month?

Before you spend more on ads, make sure intake can handle twice the leads it gets now. If it cannot, more leads just means more lost leads.

Call every web lead within five minutes, and text too. The best leads go to whoever calls first. If they do not pick up, switch it up. Send a text, then an email, then call again. Three voicemails in a row is not a follow-up plan.

The biggest injury firm we work with in Australia has about ten people answering every call live. They call every web lead within five minutes, and hit that target about 70% of the time. About a third of all their leads become signed clients. Over three years, they cut their ad spend and still signed more clients, just by fixing this step.

Morgan & Morgan has more than 100 intake staff. Our breakdown of how Morgan & Morgan gets so many cases walks through their process.

Both firms split the work. One person checks if the case is a fit. Another gets the retainer signed.

What numbers should you track?

You cannot grow what you cannot see. Track these for each case type and each channel:

You do not need fancy software. A spreadsheet you keep up to date beats an expensive system no one uses. Our guide to tracking which ad signed the case shows how to set it up.

What should you fix at each stage?

The firms I have seen grow fastest did not have the biggest budgets. They knew their numbers, called every lead fast, and added one thing at a time.

If you want help building that, from tracking each case back to its ad to the Facebook ads and intake behind it, that is what our US personal injury marketing is built for.
