If you've spent any time in lower middle market deal flow, you've probably encountered both terms. A seller says they've already commissioned a QoE and offers to share it. Or your lender asks whether a QoE exists before they'll underwrite the deal. The question worth asking in either case is: who paid for that report, and what was it designed to do?
The answer changes how much weight you should put on it.
The Basic Distinction
| Sell-Side QoE | Buy-Side QoE | |
|---|---|---|
| Commissioned by | The seller | The buyer |
| When | Pre-market or early in the process | Post-LOI, pre-close |
| Primary goal | Present earnings favorably; reduce diligence friction | Independently verify seller's earnings claims |
| Primary audience | Prospective buyers, lenders | The buyer and their lender |
| Starting orientation | Supports the seller's adjusted EBITDA figure | Questions whether the number is real |
A sell-side QoE tells you what the seller believes the business is worth and why. A buy-side QoE tells you whether that belief holds up to independent scrutiny. Both are useful. Only one is working for you.
What a Sell-Side QoE Is Actually Doing
Sellers commission QoEs for legitimate reasons. A well-prepared sell-side QoE can compress the due diligence timeline, reduce the chance of a retrade, and signal to buyers that the seller has nothing to hide.
That said, a sell-side QoE is a marketing document as much as it is a financial one. The analyst was hired by the seller, the scope was defined by the seller, and the presentation was reviewed by the seller before it reached you. Addbacks that are borderline will tend to be included rather than excluded. Revenue trends will be framed in the most favorable context.
None of this is improper, but it does mean the sell-side QoE is answering a different question than the one you need answered.
What a Buy-Side QoE Is Actually Doing
A buy-side QoE starts from a position of skepticism, which is exactly what you need when you're about to write a large check. The analyst's job is to interrogate the seller's financial presentation, not validate it.
In practice, that means requesting source documentation the seller may not have included in their package, testing whether claimed one-time items actually recurred in prior years, benchmarking owner compensation against market data, and identifying revenue or expense trends that don't show up in the headline numbers.
The output isn't necessarily a lower EBITDA number, though that's sometimes the result. Often it's a more textured picture: some addbacks confirmed, others reduced or disallowed, new adjustments identified that the seller missed or chose not to highlight.
When a Seller Offers You Their QoE
This situation comes up frequently, particularly in broker-run processes where the seller has invested in a QoE to streamline buyer due diligence. The seller's position is usually that the report speaks for itself and your own diligence is redundant.
It isn't. Accepting a sell-side QoE in lieu of your own is the financial equivalent of using the seller's home inspector when buying a house. The inspector may be perfectly competent and the report may be accurate. But they weren't working for you, and you have no way to know what questions they didn't ask.
A sell-side QoE can still be valuable as a starting point. It tells you what the seller is claiming, gives you a framework to push back on specific items, and can shorten the time your own analyst needs to get up to speed. Use it as a reference, not a substitute.
Lender Requirements Add Another Layer
Many lenders financing lower middle market acquisitions now require a QoE as part of their underwriting, and some will specify that it must be a buy-side report commissioned by the borrower. If you plan to use debt financing, confirm your lender's requirements early. Arriving at the financing stage with only a sell-side QoE in hand can delay closing or force you to commission a second report under time pressure.
The Cost Question
One reason buyers sometimes lean on a seller's QoE is cost. A buy-side QoE is an out-of-pocket expense that comes before the deal closes, with no guarantee the deal will close at all.
The more useful comparison is between the cost of the report and the cost of the risk it mitigates. If a buy-side QoE on a $2M acquisition costs $6,000 and identifies an addback that shouldn't have been included — reducing adjusted EBITDA by $100,000 and the purchase price by $400,000 at a 4x multiple — the return on that $6,000 is difficult to argue with.
