Marketing Due Diligence: The Checklist Home Services Buyers Skip and Pay For

<div class="tldr"><strong>TL;DR — Direct Answer</strong><p>Marketing due diligence for a home services deal answers three questions the QoE doesn't: where revenue actually comes from, what breaks when the founder steps back, and what the company owns versus rents. Seven zones to score: acquisition channels, attribution, intake/CSR, digital asset ownership, retention, vendor contracts, and founder dependency. Most deals check none of them formally. The revenue engine nobody inspects Buyers of home service companies will spend six figures verifying the financials, the fleet, the licenses, and the workforce, and then accept "mostly word of mouth" as the complete answer to where the revenue comes from.</p></div> <p>inspection. The month-four surprise Here's the pattern that repeats across home services acquisitions. The deal closes clean. The trailing twelve looked great. The integration plan covered finance, payroll, and key employee retention, with one line for marketing: "evaluate existing agency relationships." Month four arrives and lead flow is down 20%. The post-mortem finds what diligence never looked for. The previous owner WAS the marketing: his face on the trucks, his cell number with two decades of customers in it, his relationships feeding the referral flow. The agency contract auto-renewed at a rate nobody had reviewed since 2022. The Google Business Profile, the single most valuable digital asset in the company, is tied to a personal email belonging to someone who left in the transition. And the CRM's source data is eleven different spellings of "Google," so nobody can even measure which channel is bleeding. None of this appeared in diligence because none of it lives in a financial statement. It lives in habits, logins, and relationships, and habits leave with the founder. The reframe: you're not buying revenue, you're buying a revenue engine Trailing revenue tells you what the machine produced. Diligence is supposed to tell you whether the machine still runs when the previous operator hands you the keys. For home service companies, where demand is local, reputation-driven, and often founder-powered, that distinction is frequently worth a full turn of the multiple. The good news: marketing health is inspectable. It just needs a checklist instead of a vibe. The five red flags that predict the month- four surprise Red flag 1: "Word of mouth" as the attribution answer. Sounds like strength, doesn't it? Loyal customers, no ad dependency. Sometimes true. More often it means nobody measures anything, and "word of mouth" is the label on the mystery bucket. The test: ask for booked jobs by source for the trailing 90 days. If the answer is a shrug, you're pricing a machine nobody can see. The cost of skipping this: you can't separate durable demand from founder-personal demand until after you own it. Red flag 2: digital assets the company doesn't control. Who owns the GBP, the website domain, the ad accounts, the tracking numbers? "The marketing guy handles that" is a deal risk wearing casual clothes. Buyers have inherited companies where the agency owned the domain, the founder's brother-in-law owned the GBP login, and the call tracking numbers belonged to a vendor who held them hostage at renewal. The cost: months of lost visibility while you litigate access to assets you thought you bought. Red flag 3: founder-dependent lead flow. What percentage of high-value jobs trace to the founder's personal network, community presence, or cell phone? If the answer is "a lot" and the founder is exiting, a chunk of the trailing twelve walks out at close. The truth: founder dependency isn't a deal-killer, it's a pricing input and a transition-plan requirement. The cost of ignoring it: paying a multiple on revenue that was never the company's to keep. Red flag 4: vendor contracts nobody has read. When did anyone last review the agency agreement, the lead-gen platform terms, the auto-renewal dates? Marketing vendor contracts in this trade are full of auto-renewals, spend minimums, and cancellation windows that quietly transfer with the deal. The cost: inherited obligations to underperforming vendors, discovered after the first invoice. Red flag 5: an intake process that lives in one person's head. How do calls become booked jobs, step by step, and who owns each step? If the answer is a person rather than a process, you're buying a workflow that may not survive the transition. The truth: CSR booking rate is the most fragile number in the company during ownership change. The cost: every acquired lead gets more expensive the week the old routine breaks. The seven-zone diligence framework This is the same structure as the Marketing Blueprint diagnostic, applied pre-close. Each zone gets a score and a finding, which makes companies comparable across a pipeline of deals. Zone 1: Acquisition channels. Every lead source documented with trailing 90-day spend, lead count, and booked jobs. What you learn: which demand is bought, which is earned, which is imaginary. Zone 2: Attribution integrity. CRM source-field fill rate, value standardization, and reconciliation against ad platforms. What you learn: whether any of the company's marketing numbers can be trusted, including the ones in the CIM. Zone 3: Intake and CSR. Recorded calls scored, booking rate calculated, after-hours handling tested. What you learn: how much of the lead spend converts, and how fragile that conversion is. Zone 4: Digital asset ownership. GBP, domain, site, ad accounts, tracking numbers, review platforms: who holds the logins and the legal control. What you learn: what transfers at close versus what gets ransomed after. Zone 5: Retention and reputation. Repeat rate, review velocity and recency, membership base. What you learn: how much future revenue is already seeded versus how much must be re-bought. Zone 6: Vendor obligations. Every marketing contract pulled, with renewal dates, minimums, and exit terms. What you learn: the liabilities hiding in the marketing line. Zone 7: Founder dependency. The honest map of which demand follows the person out the door, and the transition plan that retains what's retainable. What you learn: the discount or the earnout structure the deal actually needs. What this is worth at the table Sell-side, the same framework runs in reverse: a seller who can hand a buyer clean attribution, owned assets, documented intake, and a de-personalized lead engine is defending the multiple with evidence instead of stories. That work takes 12 to 24 months, which is why it belongs in exit prep, not in the data room scramble. The buyer's diligence question and the seller's preparation question are the same question on different timelines. Either side of the table, the principle holds: in home services, the marketing function is either a story you can verify or a discount you can't avoid. Two paths from here Path one: keep running deals where marketing gets one line in the integration plan, and keep budgeting for the month- four surprise. Path two: make marketing inspection as standard as the QoE. If you're an operating partner, an M&A advisor, or a buyer with a home services deal in motion, the full framework page for portfolio work is at /private-equity, or book a working call (/audit): bring one target's numbers and we'll trace the engine live. The same diagnostic runs as a fixed-scope engagement, $7,500 per company, same seven zones every deal, so your pipeline gets comparable scores instead of anecdotes (/audit). The hard way is finding the leaks in month four. The systematic way is finding them before the price is set.</p> <h2>Frequently asked questions</h2> <details><summary>What should a marketing due diligence checklist include for a home services deal?</summary><div>Seven zones: acquisition channels with booked-job math, attribution integrity, intake/CSR performance, digital asset ownership, retention and reputation, vendor contract review, and founder dependency mapping. Each zone scored, with findings tied to valuation or transition planning.</div></details> <details><summary>How does private equity evaluate marketing in home services?</summary><div>Sophisticated buyers increasingly score marketing as an operational function: channel-level unit economics, asset control, and transferability of demand. Most still don't run it formally, which is exactly why a standardized diagnostic creates an edge across a deal pipeline.</div></details> <details><summary>How does marketing affect business valuation for a contractor?</summary><div>A demand engine that's documented, attributable, and independent of the founder supports the multiple; an opaque or founder-dependent one invites discounts, earnouts, or retrades.
