Every private equity firm I have worked with talks about Quality of Earnings, usually shortened to QoE, as if it is a single event that happens right before closing. It is not. A properly run QoE process touches a deal twice: once before the purchase agreement is signed, when it is the single most important risk mitigation tool a buyer has, and again after close, when the same discipline gets pointed inward at the newly acquired company to find and fix problems fast. Having sat on both sides of that process across 35 years of manufacturing, aviation, franchising and PE backed engagements, here is what actually happens at each stage and why so many buyers underinvest in it.
What a Quality of Earnings Report Actually Is
A QoE report is an independent financial analysis of a target company, built to answer one question the seller’s financials were never designed to answer: what does this business actually earn, on a sustainable and repeatable basis, once you strip out everything that will not show up again next year.
Seller-prepared financials are marketing documents. They are not fraudulent, most of the time, but they are optimistic by construction, because the seller and the broker built them to support a number. A QoE report is prepared by an independent team, usually led by a CPA with transaction advisory experience, and it exists to pressure test that number before the buyer wires any money.
The Pre-Purchase Due Diligence Process
A QoE engagement is built around three questions, and everything in the workstream ties back to one of them: what does this business really earn, what does it really need to operate and can the numbers be trusted at all.
What the business really earns.
This starts with two to three years of historical financials rebuilt line by line, pulling out owner perks, one-time windfalls, below-market related party arrangements and any other item that will not repeat under new ownership. A seller running personal expenses through the P&L, a lawsuit settlement booked as ordinary revenue or a family member’s lease priced well under fair value can each swing the adjusted number materially, and the adjusted number is what the purchase price actually gets negotiated against. Sitting alongside that adjustment work is a capital reinvestment review, checking whether historical earnings assumed a level of maintenance CAPEX the business cannot actually sustain going forward, which matters enormously in equipment-heavy industries like manufacturing and aviation. The revenue side gets the same scrutiny: breaking sales down by customer, by period and by type to separate durable, recurring demand from one-off projects and to surface concentration in a handful of accounts that a simple top-line trend line would never reveal.
What the business really needs.
Earnings tell only half the story. The other half is how much capital the business needs just to keep functioning. That means analyzing receivables, payables and inventory trends to set a realistic day-one working capital target, then going a step further to build the net debt schedule: deferred revenue, accrued and unfunded liabilities, unpaid transaction costs and any other item that behaves like debt at closing even though it never appears on a term sheet. Both numbers feed directly into the purchase agreement, and buyers who treat either one as a placeholder rather than an analysis tend to find themselves undercapitalized within the first few months of ownership.
Whether the numbers can be trusted.
Before any of the above matters, the underlying records have to hold up. That means reconciling bank statements against the accounting system to catch unrecorded transactions or timing gaps, reviewing key customer and vendor contracts for change of control language, and sitting down directly with the target’s finance and operations leadership. Those conversations routinely surface things no general ledger will: a key employee the business quietly depends on, an informal side arrangement with a customer, a system nobody has bothered to reconcile in years.
The output is a written report, a supporting data book and, for financed deals, documentation built to satisfy a lender. A well-run engagement is scoped and priced upfront on a two to four week timeline, because the entire point of due diligence is to remove uncertainty from the deal, not add to it through open-ended billing.
I have watched buyers skip or shortcut this process to save a few thousand dollars or beat a competing bid, and I have watched exactly how that decision plays out eighteen months later. Measured against the purchase price, a thorough QoE is the least expensive insurance policy in the entire transaction.
The Post-Acquisition Process
Here is the part most buyers do not anticipate: the same rigor that protected them pre-close needs to turn inward the moment the deal is signed, and the private equity firms that do this well treat the first 100 days after close as their own internal QoE exercise.
Validating the diligence findings against reality. Every adjustment made in the pre-purchase QoE report was an estimate based on limited access and a compressed timeline. Post-close, the new ownership group has full access to the books, the systems and the people, and the first job is to confirm those adjustments hold up. Add-backs that looked clean in diligence sometimes turn out to be more entangled in day-to-day operations than the seller disclosed.
Building the real financial infrastructure. Lower middle market companies are frequently running on financials that were adequate for a founder-owner but are not built for institutional ownership, lender covenants or board reporting. This is where a private equity portfolio company typically needs help fast: closing the books on a real monthly cadence, building a management reporting package that ties to the QoE adjusted EBITDA, standing up budgeting and forecasting where none previously existed and correcting the accounting policies flagged in diligence before they compound.
Working capital normalization. The pre-close analysis set an estimate for day one working capital. Post-close, that estimate gets tested against actual cash needs, and adjustments get made, sometimes through the purchase agreement’s working capital true-up mechanism and sometimes through operational changes to receivables and inventory management.
Closing the value creation gap. Every acquisition thesis identifies opportunities: cost synergies, pricing actions, customer diversification, add-on acquisitions. The post-acquisition financial function is what turns those opportunities from a slide in an investment memo into tracked, funded initiatives with an owner and a timeline. Without a finance leader translating strategy into execution, most of that thesis simply does not happen.
Establishing governance and control. Founder-run businesses often carry control gaps that were tolerable at a smaller scale: informal approval processes, concentrated financial knowledge in one or two people, thin segregation of duties. Institutional ownership requires closing those gaps quickly, both to protect the investment and to prepare the company for its eventual exit, which will bring its own buy side QoE process from the next buyer.
Why This Matters Regardless of Deal Size
The QoE discipline used to be reserved for larger transactions, simply because the large national advisory firms that historically performed this work carry minimum engagement sizes that price smaller deals out. That is changing, and buyers acquiring businesses well below $40 million now have access to the same caliber of CPA led analysis that used to be exclusive to the upper middle market. Deal size has never determined how much is at risk for the buyer. In many lower middle market and search fund transactions, the buyer has more personal capital and personal liability on the line than a private equity fund does on a much larger deal.
The math is straightforward. A QoE engagement costs a small fraction of the purchase price. A misjudged EBITDA, an undisclosed customer concentration or an undercapitalized day one can cost a multiple of that fee, sometimes the entire investment.
