What Buyers Look for When Buying a Business: The Wrench Group Checklist

Between 2016 and 2021, Wrench Group evaluated more than 3,000 potential acquisition targets per year in the home services industry. From those 3,000+ evaluations, they selected roughly 100 to acquire annually. The companies that made it through their filter received premium prices, operational support, and integration into a platform that sold for $14 billion. The ones that did not make it through were passed over - often with no explanation that helped the owner understand what they were missing.

Understanding what Wrench Group was actually evaluating - what moved a company from the rejection pile to the acquisition list - is the clearest answer available to the question "what buyers look for when buying a business" in service industries.

The answer is not primarily about revenue or even EBITDA margins. Those are necessary but not sufficient. The premium buyers in home services are evaluating something more specific: the quality and transferability of the operational infrastructure. Whether the business can produce consistent results without the current owner. Whether the financial records reflect reality. Whether the customer relationships belong to the company or to an individual.

What Wrench Group Was Actually Evaluating

Ken Langone's thesis was explicit: fragmented HVAC, plumbing, and home services companies could be acquired at 3x to 5x EBITDA and, as part of a consolidated platform, would be valued at 10x to 14x EBITDA on exit. The spread between those multiples was the return - 28x on the $500 million equity investment over five years.

To capture that spread, Wrench Group needed companies that could be integrated into a platform without losing the customer relationships and operational quality that made them valuable. That requirement defined their evaluation criteria.

Transferable operations. The company whose technicians follow documented procedures, whose service delivery is consistent regardless of which crew is on the job, and whose quality does not depend on the owner making the final call integrates cleanly. The one where quality depends on specific individuals - or on the owner's personal involvement - creates integration risk that buyers price into their offers.

Clean, auditable financials. Platform buyers bring institutional-grade due diligence. They will review three to five years of financial records at the line-item level. Personal expenses mixed with business expenses, cash revenue not fully recorded, add-backs that cannot be documented - each of these creates friction, triggers price reductions, or ends deals. The financial hygiene required for a platform acquisition is materially higher than what most service business owners maintain for tax purposes.

Recurring revenue mix. Installation-heavy revenue is project-dependent - it requires continuous new customer acquisition to sustain. Service agreements and maintenance contracts create predictable, recurring revenue that reduces risk and improves margin predictability. Wrench Group specifically looked at recurring revenue as a percentage of total revenue as a quality indicator. Businesses with 25% or more in recurring revenue received materially different treatment than those with 5%.

Leadership depth. The company with an operations manager who can run the business after the founder leaves integrates on a completely different timeline than the one where the owner is the operations manager. Post-close transition risk is a real factor in how buyers structure deals and what they are willing to pay upfront.

Local brand integrity. Wrench Group's specific approach was to maintain local brand identities post-acquisition - because customers trust their local HVAC or plumbing company, not a national brand. This meant they valued reputation, reviews, and community presence as real assets, not just goodwill on a balance sheet.

The GE Warning: What Manufactured Results Look Like to Buyers

Jack Welch became CEO of General Electric in 1981 and grew its market capitalization from $12 billion to $410 billion over 20 years. Fortune named him "Manager of the Century" in 1999. Business schools taught his methods as models of modern management.

But there was a mechanism underneath those results that the market did not fully understand until it was too late. GE Capital - the financial services division Welch had built to represent more than half of GE's total profits - was being used to smooth quarterly earnings. When industrial divisions had a bad quarter, GE Capital could manufacture the missing profits through financial transactions. For 20 years, GE hit its quarterly earnings targets with almost uncanny precision.

When the 2008 financial crisis exposed the true nature of those instruments, GE Capital's smoothed earnings became toxic liabilities. GE needed a $139 billion government-backed bailout. The stock fell from $42 to $6. In 2018, GE was removed from the Dow Jones Industrial Average after 111 consecutive years. In 2024, GE completed its breakup into three separate companies.

The relevance for a business sale is direct: sophisticated buyers - the institutional-grade due diligence that platform acquirers bring - will distinguish between real performance and manufactured results. Adjusted EBITDA that cannot be clearly explained and documented. Add-backs that do not reflect genuinely one-time items. Revenue recognition that accelerates income into the measurement period. All of these are patterns that experienced buyers have seen before and know how to find.

The business that shows clean, conservative financials with clearly documented add-backs creates confidence. The one that requires extensive explanation of why the numbers look the way they do creates skepticism - and skepticism in due diligence converts to price reductions, deal restructuring, or failed transactions.

The Netflix Keeper Test: What Retention-Based Thinking Produces

Netflix CEO Reed Hastings introduced a people management framework that became known as the "Keeper Test": as a manager, ask yourself whether you would fight hard to keep each person on your team if they told you they were leaving. If the answer is no for someone, they should be moved on now - with a generous severance - rather than kept in a role where they are occupying a position that a better-suited person could fill.

The Keeper Test is not primarily a hiring framework or a firing framework. It is a quality framework - a commitment to maintaining a team where every person is genuinely excellent at their role, where accountability is real and visible, and where the bar for staying is consistent performance at a high level.

What the Keeper Test produces, when applied consistently over years, is exactly what sophisticated buyers look for: a team of people who are genuinely capable, who understand their roles, and who would remain with the business after a change in ownership because they are engaged and performing - not because inertia or personal loyalty to the founder keeps them there.

Buyers evaluating a service business ask: what happens to the team when the founder leaves? If the answer is "several key people might leave because their relationship was with the owner personally," that is a significant integration risk. If the answer is "the team has been built for performance and compensation reflects it," that is an asset that protects post-close value.

What This Means in Practice

The three frameworks together - Wrench Group's operational evaluation, GE's financial transparency lesson, and the Netflix retention principle - describe what premium buyers are actually looking for when they evaluate a service business acquisition.

It is a business where the operations are documented and transferable, the financials are transparent and verifiable, the recurring revenue is substantial, and the team would remain and perform well after the founder leaves. None of those characteristics can be assembled in the 90 days before going to market. All of them require 12 to 24 months of deliberate building.

The practical question is not whether your business meets this standard today. It is whether, with 12 to 24 months of focused preparation, it could. For most service businesses in the $3 million to $25 million revenue range, the answer is yes. The gaps are specific, addressable, and worth addressing - because the difference between what Wrench Group paid for the businesses that passed their filter and what businesses below that filter received was measured in millions of dollars per transaction.
