“PE due diligence is not personal — it's systematic. Every request, every model, every customer call is part of a process designed to verify what the seller claimed and price what they didn't.”
How PE Due Diligence Differs from Strategic Buyer Due Diligence
Strategic buyers (regional pest control operators, national chains) often complete due diligence with their own team — a combination of operational management and a CPA or attorney. PE buyers have dedicated deal teams: a deal lead (associate or VP-level), a financial analyst, a legal team, and often third-party advisors (Quality of Earnings accountants, environmental consultants, market researchers). The process is more structured, more document-intensive, and more analytically rigorous than a typical strategic buyer's review. Sellers selling to PE for the first time should expect a much more intensive process than they might have anticipated from an independent buyer.
Quality of Earnings (QofE) — The Financial Core
The centerpiece of PE financial due diligence is the Quality of Earnings (QofE) analysis — a report prepared by an independent accounting firm (hired by the buyer, paid for by the buyer) that verifies and recasts the business's financial statements. The QofE tests: whether reported revenue is real and collectible (sampling invoices against bank deposits), whether add-backs are legitimate and documented, whether SDE margins are sustainable, and whether any one-time revenue items are included in the recurring run-rate. The QofE team will request direct access to your QuickBooks or accounting system, bank statements, routing software exports, and payroll records. This is the most invasive part of PE due diligence and the phase where sellers most frequently encounter challenges if financial documentation is not clean.
Customer Cohort Analysis
PE buyers perform detailed customer cohort analysis that most strategic buyers don't attempt. The cohort analysis tracks customers by acquisition year (2018 customers, 2019 customers, etc.) and measures their retention, revenue growth, and service frequency over time. This analysis reveals the business's true customer lifetime value and attrition rate in a way that simple trailing-12-month revenue cannot. A pest control business with consistent 85%+ retention across all customer cohorts tells a very different story than one where 2021 customers have been retained but 2019 customers have largely churned. Sellers should run cohort analysis on their own customer data before PE due diligence begins — identify weaknesses before the buyer's team does.

Market and Competitive Analysis
PE due diligence includes a market analysis component: the buyer's team (or a third-party firm) reviews the competitive landscape in the seller's service territory. Who are the competitors? What are their market shares? Is the seller gaining or losing market share? Are there any market entry threats (new regional competitors, national brands entering the market)? For sellers, this means the PE buyer will know your competitive position from sources independent of your own description. Any inconsistency between what the seller has represented and what the market analysis reveals creates credibility damage during due diligence. Sellers should be accurate and complete in describing their competitive position in the CIM.
Employee and Management Interviews
PE buyers typically request management interviews — conversations with key employees and managers separate from the owner. The purpose: independently verify the operational story the owner has told. A PE buyer who interviews an operations manager and gets different answers about customer retention, technician management, or growth plans than the owner provided has discovered a credibility gap. Sellers should brief key employees about what topics are appropriate to discuss with buyers and ensure that descriptions of the business's operation are internally consistent. Management interviews are not depositions — employees can decline to answer questions that feel inappropriate — but they are substantive conversations that matter.
How Sellers Can Navigate PE Due Diligence
Sellers working with PE buyers for the first time should: (1) Retain a broker with PE transaction experience — a broker who has worked through multiple PE due diligence processes knows what will be asked and can help prepare. (2) Organize a virtual data room (VDR) before the LOI closes — PE teams expect structured, organized document access. (3) Prepare a management presentation deck — PE buyers use a management presentation early in due diligence to understand the business story from the seller's perspective. (4) Pre-build the QofE reconciliation — reconcile your P&L to tax returns and bank statements in a clear spreadsheet before the QofE firm asks. (5) Be transparent — PE teams have seen every type of financial presentation. Attempting to hide issues is far more damaging than proactive disclosure.
