There is a funny thing that happens as an MSP grows. In the beginning, every fish looks like dinner.
A dentist calls. Great. A manufacturer calls. Great. A nonprofit needs help. Also great. A law firm, a church, a warehouse, a retail shop, a CPA firm, a tiny startup with big dreams and no budget—early on, most MSPs say yes to all of them because cash flow matters and learning matters. You are still figuring out who you serve well, what kind of work is profitable, what kind of client relationship feels healthy, and what kind of client makes your staff groan when the phone rings.
That stage is not wrong. It is how many MSPs survive long enough to become something more intentional. The mistake is staying there forever, or swinging too far in the other direction and letting one big client become the whole story.
What do we need! Clients! How are we going to get them? Haven’t a clue!
I got my start down the MSP path through referrals. I was working for a company that did big ERP installs for school districts. I worked with the school board, the superintendent, the principals and the teachers. Turns out every teacher has a brother that owns a business and needs IT help. These unsolicited referrals launched my MSP career.
Most MSP owners did not start with a perfectly defined ideal client profile. They started with a phone, a reputation, a little courage, and the willingness to solve problems. That means the early client list usually looks like a community directory rather than a strategy document.
There is value in that. A broad client base teaches you what different industries expect from technology. You learn which clients respect professional advice and which ones want to argue over every invoice. You learn which verticals have similar applications, similar compliance pressure, similar hours, and similar tolerance for downtime. You also learn which clients are simply not worth the emotional energy they consume.
This is the small-fish stage. Lots of little clients. Lots of variety. Lots of lessons. The owner is still absorbing the market and learning through experience. Revenue may be choppy, but the risk is usually spread out. If one client leaves, it hurts, but it does not sink the boat.
Then patterns start to appear
As the company matures, patterns emerge. You begin to see that certain kinds of clients are easier to support, easier to sell to, and easier to retain. Maybe legal firms fit your service model. Maybe accounting firms appreciate your security work. Maybe manufacturers have predictable needs and value uptime enough to pay for it. Maybe healthcare seems attractive until you realize your team does not enjoy the compliance burden or the urgency.
This is where growth starts to become strategic. You’re no longer asking, “Who will buy from us?” The better question becomes, “Who do we want to buy from us?”
That question changes everything. It affects marketing. It affects pricing. It affects the stack. It affects hiring. It affects documentation. It affects how sales conversations sound. When you understand your best client profile, you stop sounding like every other MSP in town and start sounding like a company that knows exactly who it helps and why.
Buyers notice this, too. A focused MSP is easier to understand. It has a cleaner story. It can usually explain its service delivery model, its client acquisition process, and its margins with more confidence. That does not mean every MSP must serve only one industry. It means the MSP should be able to explain why its clients are the right clients.
Specialization is not the same as dependency
My first hire ended up shaping my MSP. He was a former CAD guy and our local market is full of shops that hire CAD guys. They could all relate to him. For my part, I love knowing how stuff works and I come from a tradesman family, where I was taught how things work. I love everything about the manufacturing process.
Did we end up with a specialization? Yes and no. Surrounding manufacturing are engineering, designers, prototyping, procurement and other firms like ours that mostly support them via professional service. These were our clients. We spoke the language. We knew the apps. We got the strategy.
But here is where owners can get into trouble. Serving many clients in one industry can be smart. Depending on one large client is something else entirely.
A large client can feel like validation. They chose you. They trust you. The monthly agreement is huge! The projects are large. The logo looks good on the client list. For a while, it may feel like you have crossed into a new stage of business ownership. Instead of chasing dozens of small opportunities, one big client can move the revenue needle all by itself.
But big clients carry gravity. They pull attention. They pull staff. They pull process. They pull pricing exceptions. They pull the owner back into the business. Before long, the MSP may be making decisions around the needs of one client rather than the needs of the company.
That is not specialization. That is concentration risk. And whales sometimes jump on your boat and sink it – accidentally.
Why buyers care about client concentration
When a buyer looks at an MSP, they are not only buying today’s revenue. They are buying the likelihood that the revenue will still be there after closing. That is why client concentration matters so much in a sale.
If one client represents a significant portion of revenue, the buyer has to ask uncomfortable questions. What happens if that client leaves? Is the relationship with the MSP or with the owner personally? Are the terms market rate, or did the MSP bend the rules to keep the client happy? Does the service team have capacity for the rest of the business, or has this one client consumed the best people? Would the client remain after an ownership change?
Those questions do not make the business unsellable, but they do change the risk calculation. Risk changes value. A buyer may lower the offer, require a larger earnout, hold back more of the purchase price, or insist that the seller stay involved longer. In some cases, a buyer who liked everything else about the MSP may walk away because the company is too dependent on one relationship.
You can’t have one whale. If you like whales, you’ve got to get yourself a pod of them. See our podcast episode on this.
This is the frustrating part for owners. The large client may have made the company look bigger. It may have increased revenue and profit. It may have solved short-term cash flow problems. But at the sale table, that same client can become a discount instead of a premium.
How the buyers see it
Buyers hate risk. That means owners need to watch the client list as carefully as they watch monthly recurring revenue.
Ask yourself:
- How much revenue comes from the largest client?
- How much comes from the top three clients?
- Would the business still be healthy if the largest client left?
- Are we pricing that client correctly, or have we trained ourselves to accept exceptions?
- Does the team serve this client through documented process, or through heroic effort?
- Is the owner still the reason that client stays?
These are not just operational questions. They are value questions. If you can answer them cleanly, you have a better business. If you cannot, you have work to do before a buyer asks the same questions with a due diligence checklist in hand.
Grow on purpose
The story of MSP growth is often the story of moving from opportunity to intention. In the beginning, you take the work that helps you survive. Over time, you learn which clients help you build. Eventually, if you are paying attention, you shape the company around the clients that make the business stronger, more repeatable, and more valuable.
That is the migration from little fish anywhere to the right fish in the right pond.
But do not confuse one very large fish with a healthy pond. A whale can feed the company for a while, but it can also distort the ecosystem. It can make the company appear larger than it really is, more stable than it really is, and more valuable than a buyer will believe it is.
If you are building with a future sale in mind, client mix matters. Industry focus can increase value. Repeatability can increase value. A clear market position can increase value. But dependence lowers value, because buyers do not pay full price for revenue they are afraid might swim away.
So yes, grow. Land better clients. Move upmarket when it makes sense. Build a reputation in the industries where your team does its best work. Just keep enough balance in the client base that the business remains a business, not a single relationship with a staff attached. Big fish are nice. A healthy pond is better.
