"Middle market" gets thrown around loosely. Owners hear it and assume it means something bigger and more sophisticated than what they have, without a clear sense of where the line actually sits.
Here's roughly where I draw it. Main street businesses generally run $3 million to $5 million in revenue or below, with SDE (Seller's Discretionary Earnings) around $1 million or less. Once a business is generating $5 million or more in revenue and producing more than $1 million in EBITDA rather than SDE, it's stepped into middle-market territory.
That shift in terminology, from SDE to EBITDA, isn't just semantics. It reflects a business that's stopped being an extension of its owner and started operating like an actual company.
What Actually Changes as a Business Moves Up
The dollar figures matter less than what happens around them.
Quality of earnings reviews become far more common at this level. They're not cheap, so most smaller deals never get one, a basic set of clean financials is usually enough. But as deal size grows, so does the risk on both sides, and the need for financials that hold up under real scrutiny gets a lot more intense. That's when a full QoE stops being optional.
The buyer pool changes shape too. Middle-market deals bring in acquisition groups and private equity buyers who move differently than individual main street buyers. Experienced buyers can look at a set of financials and move quickly. They know what's actually a red flag and what isn't. Less experienced buyers, by contrast, tend to get hung up on the wrong things entirely, sometimes stalling a deal over something that shouldn't matter while missing something that should.
Is Your Business One of Them?
Most owners don't wake up one day running a middle-market business. It happens gradually.
When I'm looking at a company producing around seven figures in earnings, I'm checking for a few specific things: are there real operating procedures in place, or does everything still run through the owner's head? How involved is the owner in day-to-day operations? What does client concentration look like? Those answers tell me whether a business has actually progressed from an owner-operator business into something that can stand on its own, regardless of what the revenue number says.
Why This Distinction Actually Matters
It's not just industry jargon. It changes how a business should be marketed, who it should be marketed to, and what kind of diligence process to expect. It also matters who's running the deal. We work both ends of this spectrum, with dedicated experience and in-house teams built around main street transactions and around middle-market deals, because the two aren't the same skill set wearing a different price tag.
Common Questions I Hear About Middle-Market Deals
What's the actual difference between SDE and EBITDA, and why does it matter which one applies to my business?
SDE accounts for the fact that a small business owner is typically drawing a salary and running some personal benefit through the business, so it adds those back to show the total financial benefit to an owner-operator. EBITDA doesn't make that adjustment, because a middle-market business is generally expected to run with professional management already in place, whether the current owner stays or not. Which one applies to your business is itself a signal of which category you're really in.
Does my business need a Quality of Earnings review if I'm thinking about selling?
Not necessarily, and for most main street businesses it isn't worth the cost. It becomes much more common as deal size grows, since the risk to both sides increases and buyers want financials that hold up under real scrutiny. If your earnings are approaching seven figures, it's worth at least discussing whether a QoE makes sense for your specific deal.
How do I know if my business has crossed into middle-market territory, even if the revenue number seems borderline?
Revenue and earnings are a starting point, not the full answer. I look at whether real operating procedures exist independent of the owner, how involved the owner still is in daily operations, and how concentrated the client base is. A business can technically hit the revenue threshold and still function like a main street business if those other pieces aren't in place, and vice versa.
If you're not sure which side of that line your business falls on, that's usually the first thing worth figuring out, before pricing, before marketing, before any of it.
