Not All Revenue Is Real
Let me teach you something that took me several scale up journeys to fully understand.
Not because it wasn’t explained to me. Because the first time a Quality of Earnings report landed on a business I was running, I thought I understood it. I didn’t. Not really. I understood the words. I didn’t understand what was actually happening to the number I’d been reporting with confidence for three years.
What was happening was this: a team of very calm, very methodical analysts was taking my revenue line apart like a watch movement. Not to find fraud. Not to catch me out. To answer one question that I, as the CEO, had never thought to ask about my own business.
What kind of revenue is it?
That question is the foundation of Quality of Earnings analysis. And it’s the question that creates the gap between what founders think their business is worth and what a sophisticated buyer is actually willing to pay for it.
What a Quality of Earnings Report Actually Does
Most founders encounter a QoE for the first time when a buyer orders one during due diligence. Which is, to put it politely, the worst possible moment to be introduced to the concept.
By that point, the analysts aren’t working for you. They’re working for the buyer. Their job is to determine whether the earnings you’ve been reporting accurately represent what the buyer is actually acquiring. Not whether you’ve been dishonest (most founders haven’t) but whether the numbers are underwritable. Whether a PE firm can look at your revenue, model it forward three to five years under their ownership, and have reasonable confidence the picture holds.
A QoE is not an audit. An audit confirms that your numbers are mathematically accurate and compliant with accounting standards. A QoE asks a different question entirely: are these numbers a reliable guide to the future? Accurate and underwritable are not the same thing. Founders almost always conflate them.
The first time I sat with a QoE report on one of my businesses, the revenue figure looked different to the one I’d been living with for years. Not wrong, exactly. Just smaller, somehow. Adjusted. Like someone had run the numbers through a filter I hadn’t known existed.
They had. That’s precisely what QoE does.
Revenue Is Not a Number. It's a Stack of Assumptions.
Here is what buyers understand about revenue that most founders don’t.
Every revenue figure is a composite. It contains different types of income, each with a fundamentally different risk profile, all added together into a single line that obscures more than it reveals. When a buyer looks at your revenue number, they don’t see a total. They see a question: what’s inside this?
The taxonomy that QoE analysis applies runs roughly like this.
Contracted revenue is the highest quality. A customer has signed a multi-year agreement with defined terms, renewal obligations, and penalties for early exit. It will almost certainly be there next year. Buyers underwrite this at full value, sometimes at a premium, because it gives them visibility into future cash flows that reduces the risk of the investment.
Recurring revenue is strong but softer. A customer hasn’t signed a long-term contract, but they subscribe, renew, or purchase on a reliable cycle. The pattern is consistent. Churn is low. Buyers value this well, but they will probe the retention data and want to understand what drives the renewal decision. Critically, whether that driver survives a change of ownership.
Repeat revenue is relationship-based. A customer keeps coming back, not because they’re contractually obliged to, but because they like dealing with you, trust your team, know how you work. This is common in services businesses, and it’s not worthless. But buyers apply a discount, because the question they’re really asking is: does this relationship follow the business, or does it follow the founder?
One-time revenue is exactly what it sounds like. A project, a consultancy engagement, a one-off sale. It happened. It won’t happen again in the same form. For revenue quality purposes, buyers typically exclude this from their forward model entirely. It is not a basis for valuation.
Now consider what this means in practice.
Two businesses. Both reporting $4M revenue. Business A: 70% contracted or recurring, 20% repeat, 10% one-time. Business B: 20% contracted or recurring, 40% repeat, 40% one-time. Same number on the page. Entirely different businesses when the QoE is done. Business A’s revenue is largely visible, predictable, and underwritable. Business B’s revenue has to be rebuilt from scratch every year. A buyer knows that, even if the founder doesn’t quite see it that way.
That difference is not a rounding error. It is multiple points of valuation.
The Three Adjustments That Move the Number
This is where QoE gets its teeth. And where founders who haven’t been through the process before tend to feel a particular kind of vertigo.
The first adjustment is revenue normalisation. Analysts strip out anything that inflated the reported number but won’t recur. A large one-off project that distorted the annual figure. A customer relationship that ended mid-year and was replaced by something smaller. A pricing uplift that was a timing anomaly rather than a structural improvement. Each of these gets removed from the number the buyer is actually using to build their model. If your reported revenue is $4M but normalised revenue is $3.4M, the multiple applies to $3.4M. That is a meaningful difference in what lands in your bank account.
The second adjustment is concentration haircuts. If a significant portion of your revenue sits with one or two customers, buyers don’t simply note the risk and move on. They model what happens if that customer leaves, and they price accordingly. In practice this often means applying a discount to the revenue attributable to any customer above a certain threshold, on the basis that concentration represents a fragility the buyer is having to absorb. I have watched deals where a single customer relationship representing 35% of revenue cost a founder two full turns of multiple. Not because the relationship was at risk. Because the buyer couldn’t underwrite it with confidence. Uncertainty is always priced.
The third adjustment is growth quality interrogation. Revenue growth looks good on a chart. But QoE analysts ask what’s driving it. Growth from new customer acquisition is strong: it demonstrates the sales engine works and the market is receptive. Growth from expansion within existing accounts is excellent: customers are finding more value and deepening their commitment. Growth from price increases is moderate: it works until it doesn’t, and buyers want to understand the ceiling. Growth from a handful of large project wins is problematic: it is not evidence of a repeatable engine, and buyers will not extrapolate it. If your growth story has been driven by factors that aren’t systematically reproducible, a QoE will find that, and it will adjust the forward model accordingly.
By the time those three adjustments have been applied, the revenue number a buyer is working from can look materially different to the one you presented at the start of the process. I have been in that position. It’s an uncomfortable experience. Not because anyone is being unfair, but because you’re watching your own assumptions get tested in real time by people whose entire job is to stress-test assumptions.
What This Means for How You Build Revenue Now
The practical consequence of understanding QoE analysis is not that you should panic about your current revenue mix. It’s that you should see it clearly, probably for the first time.
Most founders build revenue the way most businesses grow: opportunistically. You take the work that’s available, serve the customers who show up, and expand wherever expansion is possible. That’s entirely sensible. But it produces a revenue mix that has never been stress-tested against the question a buyer will eventually ask, because you were never thinking about that question.
Once you understand how revenue gets graded, you can start making deliberate choices. Not all growth is equal. A dollar of contracted recurring revenue is structurally more valuable than a dollar of repeat project revenue. Not just at exit, but today, in the resilience and predictability it gives the business. Moving a customer from an informal repeat arrangement to a signed retainer or multi-year contract isn’t just tidiness. It changes the quality grade of that revenue. Multiple small decisions like that, made consistently over two or three years, shift the composition of your revenue in a way that a buyer will eventually recognise and pay for.
The same applies to concentration. Reducing the percentage of revenue held by your largest customers isn’t just risk management. It is directly improving the underwritability of your business. Every point of concentration you remove is a point of discount a buyer no longer has justification to apply.
None of this requires a dramatic strategic pivot. It requires knowing what you’re building toward, and letting that shape how you pursue and structure revenue from here.
The Lens You Didn't Know You Needed
Here’s the reframe I wish someone had given me before the first QoE landed on my desk.
Quality of Earnings analysis is not something that happens to you in a sale process. It is a lens. One that buyers use as a matter of course and founders almost never apply to their own businesses. Which is precisely why the gap between founder expectations and buyer valuations is as wide as it so often is.
The founders who understand this well enough to run that lens on themselves, to look at their own revenue and ask what kind of revenue is it, really, are the ones who walk into a sale process without surprise. They already know what their revenue is worth. They’ve been building toward a better answer for years. They don’t need a QoE report to tell them what’s in their own business, because they’ve been asking the question themselves.
The number at the top of your P&L is not your valuation. It’s the starting point for a conversation about quality. The founders who understand that distinction early enough to act on it are the ones who end up on the right side of that conversation.
