Ask this question in almost any searcher community and you'll get a version of the same story back within an hour: a buyer found a plumbing company they love, the numbers work, and the broker just said no because they're not a licensed plumber.
I watch this happen constantly. It's probably the single most repeated question I see in the buyer communities I follow: how do you buy a trade business, plumbing, HVAC, electrical, even a therapy practice, when the license belongs to the seller and not to you?
Sellers and brokers say no reflexively. Some of them have never sold to a buyer without the trade credential and don't know it's solvable. But I've watched real buyers close these deals anyway, and the structures they use are teachable.
Why the license is the real asset
In a licensed trade, the license is often the thing that lets the business legally operate at all. Lenders know this, and the SBA in particular wants comfort that someone with the credential is tied to the business, either as the buyer or through a formal written arrangement.
States differ a lot here, too. Don't assume the structure that worked for someone else's deal transfers cleanly to yours. Check your state's specific rules before you build a deal around an assumption.
Structure 1: the seller keeps working, just not as the owner
The cleanest version I've seen: a buyer closed on a plumbing company for about $2.8M (roughly $2M for the business, the rest real estate) at a 3.3x SDE multiple. The seller held the Master Plumber license, and instead of walking away, he signed a management agreement letting the buyer operate the business under his license for 4 years.
The SBA required that signed agreement before it would fund the loan. Without it, the buyer would have had to hand over 5% or more equity to a staff plumber, purely to keep that person around and keep the license attached to the business.
There's a bonus effect worth noting. That management agreement functions like a second non-compete. For 4 years, the seller can't take his license anywhere else, which means he can't quietly go start or staff a competing shop down the road. It locks him in twice: once on the sale agreement, and again on the license.
The plumbing deal above is actually a good example of a second protection too, even though the buyer probably wasn't thinking of it in these terms. There were 2 people who could hold the master license: a staff plumber who'd been there 13 years, and the seller, now committed through the management agreement. Neither one alone could shut the business down by walking out.
That's the pattern to aim for, not a single license holder you're dependent on. An employee plus a seller staying on part time means no single person can hold your business hostage by threatening to leave.
Structure 2: the seller sticks around as an employee
I've also seen this handled with the seller staying on as a 1099 employee for roughly 12 months post-close, specifically to qualify the license during the transition period. It's a shorter commitment than a multi-year management agreement, and it works well when the buyer plans to bring in a new licensed hire or pursue their own license within that window. The tradeoff is you're leaning on a shorter runway, so the hiring or licensing plan has to actually happen on schedule.
The trap: giving away equity you didn't need to give
Here's where buyers cost themselves real money. The plumbing buyer above nearly did: his original plan, most of the way through the deal, was to hand 5% equity to the staff Master Plumber to keep him around. No term limit, permanent equity handed out because it felt like the only lever available.
The management agreement replaced that plan late in the process, and he closed with 100% ownership. I'd push hard to explore that route before defaulting to equity. A management agreement expires; equity handed out to keep someone around does not.
Trades aren't the only place this shows up. I followed a physical therapy practice acquisition that closed around $5.5M at a 4.3x multiple, negotiated down about $135K during diligence. The practice's licensed clinician legally is the practice until a replacement is hired and credentialed, so the bank required the seller to stay on at 5% equity until that replacement was in place. Same logic as the plumber, different license.
Know your risk tolerance
I want to give the honest counterweight here, because it's a real position and not a lesser one. I've seen an experienced buyer with her own GC license and industry certification say flatly that she excludes plumbing and HVAC from her buy box entirely. Her reasoning: getting licensed in those trades is genuinely hard, and she doesn't want to be beholden to someone else's credential, no matter how well-structured the agreement is.
That's a legitimate call. A management agreement or a redundancy structure reduces the risk of a licensing problem. It doesn't eliminate it. If you'd rather not carry that risk at all, cross those categories off your list and don't feel like you're missing out on a trick everyone else figured out.
The lender angle
Lacking industry experience is usually solvable on its own, separate from the licensing question. I've watched lenders get comfortable with inexperienced buyers through a bigger down payment, a GM already in place, or a seller staying involved for 6 to 12 months post-close. In one HVAC deal I followed, the buyers had zero HVAC background and structured around it by bringing the seller in as a minority partner (19% equity) rather than a simple employee, which kept him financially motivated to make the transition actually work.
That said, I'd hedge here: some lenders won't touch certain trade categories at all, licensing structure or not. It's worth asking your banker directly, early, before you fall in love with a deal that a specific lender simply won't underwrite.
