How to Build a Marketing P&L That Connects Spend to Settlement Revenue

Most PI firms have a marketing budget. Very few have a marketing P&L.

The difference is not semantic. A budget tells you how much you plan to spend. A P&L tells you whether that spending is generating a financial return — and by how much, broken out by source, case type, and time period. If you are approving a $200,000 monthly marketing budget without a corresponding P&L, you are making a capital allocation decision without a financial model.

This article shows you how to build a marketing P&L that connects your spend to actual settlement revenue — so that the marketing conversation in your firm becomes a financial conversation.

Why a Marketing P&L Is Different From a Marketing Report

A marketing report shows you what happened: leads received, cases signed, cost per lead, conversion rate. These are activity metrics. They tell you how busy the machine was, not whether the machine is generating profit.

A marketing P&L takes those same inputs and runs them through a financial model. It asks: for every dollar we spent on marketing and intake, how much revenue did we generate — and what was the margin?

The PI payment lag makes this harder than in other industries. Your marketing spend this month will not produce settlement revenue for 6 to 18 months. A well-constructed marketing P&L accounts for this using expected value models and cohort tracking instead of assuming real-time revenue recognition.

Step 1: Define Your Cost Lines

The expense side of your marketing P&L has three components. Get these right first.

Direct Acquisition Spend

This is the easiest line to populate. Include every dollar paid directly to lead sources:

• Lead vendor invoices (pay-per-lead, pay-per-call, shared and exclusive leads)
• Google Ads and Local Service Ad spend
• Facebook and Instagram advertising
• Billboard, TV, and radio if tracked
• SEO and content agency retainers (apportion to lead generation, not brand building)
• Referral program costs

For a firm spending $200,000 per month across five vendors, this line is straightforward. Keep it by vendor so you can attribute outcomes at the source level.

Intake Labor Cost

Intake is the operational cost of converting leads into signed cases. Without intake staff, leads do not become cases — so intake labor is a legitimate cost of case acquisition.

Calculate the fully-loaded cost: base salary plus benefits, payroll taxes, and any variable compensation. For four intake specialists at $55,000 base with 28% overhead, the annual fully-loaded cost is approximately $281,000, or $23,400 per month. Add a proportional share of intake supervisor time if applicable.

Overhead Allocation

This is optional but makes the P&L more honest. Allocate a portion of firm overhead — office space, administrative staff, software subscriptions used by marketing and intake — proportionally to the intake team's headcount share. For many firms, this runs $4,000 to $8,000 per month.

Total monthly cost example: $200,000 direct spend + $23,400 intake labor + $6,000 overhead = $229,400 per month in total marketing and acquisition cost.

Step 2: Define Your Revenue Lines

The revenue side of the marketing P&L requires more structure because PI revenue is deferred. You are not recognizing revenue in the month marketing spend occurs — you are recognizing it when cases settle, which may be 12 to 24 months later.

There are two approaches, and most firms should use both.

Approach A: Expected Revenue Per Signed Case (Leading Indicator)

Assign an expected revenue value to each signed case based on case type and historical average settlement. For a motor vehicle accident case where your firm averages $22,000 in settlement with a 33% contingency fee, the expected revenue per case is $7,260.

When a lead from Vendor X becomes a signed case, you can immediately assign $7,260 in expected revenue to Vendor X's P&L line. This is not accrued revenue — it is expected value that helps you make real-time decisions without waiting 18 months for confirmation.

Approach B: Realized Revenue Attribution (Lagging Indicator)

When cases settle, attribute the contingency fee back to the originating lead source. This requires source tagging in your case management system — every case file should record the lead source that produced it.

This is the most accurate revenue line but has an 18-month lag. Use it to validate your expected value assumptions over time and to identify which sources produce systematically higher or lower settlements than expected.

Step 3: Build the P&L Structure

A marketing P&L for a PI firm should be structured by vendor or channel, then aggregated to total. Here is the format:

Per Vendor (Monthly)

• Gross spend: What you paid the vendor this month
• Leads received: Volume from this vendor
• Signed cases: Leads from this vendor that became signed cases
• Cost per signed case: Gross spend ÷ signed cases
• Expected case revenue: Signed cases × average expected fee
• Expected case acquisition ROI: (Expected revenue ÷ Gross spend) − 1

Blended Total (Monthly)

• Total acquisition spend (direct + intake labor + overhead)
• Total signed cases
• Blended cost per signed case
• Total expected case revenue
• Marketing P&L margin: (Total expected revenue − Total cost) ÷ Total expected revenue

Step 4: Handle the Time Lag With Cohort Tracking

The most common mistake in PI marketing P&Ls is matching current spend to current revenue. February's settlements came from October leads. If you divide February's marketing spend by February's settlements, the number is meaningless.

Cohort tracking fixes this. Instead of a calendar-month view, track lead cohorts: all leads received in October, what happened to them through February, how many became signed cases, how many of those cases have settled.

Over time, you build a cohort-based P&L that shows the full lifecycle revenue of every marketing dollar by the month it was spent — not the month the cases happened to close.

Step 5: Set P&L Targets and Review Cadence

A marketing P&L is only useful if you act on it. Set these thresholds:

• Maximum acceptable cost per signed case: Based on your average case value and target marketing margin. For most PI firms with $7,000–$10,000 average contingency fees, this falls in the $2,500–$5,000 range.
• Minimum acceptable expected case acquisition ROI: A reasonable target is 80–120% — meaning for every $1 spent on marketing, you expect $1.80 to $2.20 in contingency fee revenue.
• Marketing margin floor: The percentage of expected case revenue left after acquisition costs. A healthy floor for mid-size PI firms is 60–70%.

Review this P&L monthly. Any vendor consistently above your cost-per- case ceiling should be on a 90-day improvement plan or exit plan. Any vendor consistently outperforming should be a candidate for increased budget allocation.

What This Framework Reveals That Your Current Reports Hide

When PI firms build this P&L for the first time, they almost always find the same thing: two or three vendors are carrying the portfolio, and one or two are destroying margin. The blended averages they were reviewing masked the variation.

Firms that build a vendor-level marketing P&L and act on it consistently report 15–20% improvement in marketing ROI within the first 90 days — not because they found better vendors, but because they stopped subsidizing the worst ones with the best ones' budget.

That visibility is what converts your marketing budget from an expense line into a managed investment portfolio. And it is what makes the monthly marketing meeting a financial conversation instead of a gut-check.
