If you’re thinking about selling your MSP, buyers will look at much more than revenue and profitability. One of the key factors they will assess is customer concentration: how much of your revenue depends on your largest clients.
Customer concentration can affect how buyers view your business, the questions they ask during due diligence, and even how they structure their offer. Understanding it early gives you time to review your client mix and prepare before bringing your MSP to market.
Before a buyer digs into your financials line by line, they’ll usually ask for a client list broken down by revenue. It’s often one of the first documents a serious buyer or broker wants to see, sometimes before margins or growth figures are discussed. That single document tells them, in one glance, how fragile or stable your business really is.
A well-diversified client base signals resilience. It shows that the business could absorb the loss of any single account without causing major disruption. An MSP that relies heavily on one or two clients tells a different story, and buyers will quickly factor that risk into their valuation. This is why customer concentration deserves attention well before you put your business up for sale.
There’s no single rule that applies to every deal, but most buyers have a fairly consistent view of where comfort ends, and caution begins.
If you’re wondering what level of customer concentration buyers consider too high, these general ranges are a useful starting point, although each buyer’s risk tolerance will differ:
It’s worth remembering that crossing one of these thresholds doesn’t automatically kill a deal. It just means buyers may want additional protections built in, which we’ll get to shortly.
MSP valuation multiples reflect a buyer’s view of how sustainable the company’s earnings will be after the sale. If a large proportion of your EBITDA depends on one major customer, the buyer may be less willing to apply the same multiple they would offer for a business with a more balanced client base.
For example, two MSPs may generate exactly the same EBITDA but receive different valuations. If one could lose a significant share of its earnings following the departure of a single customer, a buyer may apply a more conservative multiple to reflect that risk. The difference is not the current EBITDA figure. It is the buyer’s level of confidence that those earnings will continue under new ownership.
A buyer may still be willing to move forward despite customer concentration, but the purchase price may not be the only thing that changes. In a managed service provider acquisition involving a concentrated client base, buyers often adjust the deal structure to limit their exposure.
Common protections include:
In plain terms, more of your payout gets pushed to after closing. It’s a reasonable way for buyers to manage risk, but it can also mean waiting longer to receive the full value of the deal.
Experienced owners often assume they understand this risk because they’ve lived with it for years. And fair enough: you probably manage that relationship carefully day to day. But familiarity can create blind spots that are easy to underestimate until a buyer points them out.
What feels manageable to you because you’ve nurtured that account for a decade can look precarious to someone stepping in fresh with no personal relationship to lean on. It’s worth stepping back occasionally and viewing your client list the way an outside buyer would, rather than through the lens of the trust you’ve built over the years.
The good news is that customer concentration is one of the more manageable issues in exit planning, provided you begin early enough.
A few practical steps tend to make the biggest difference:
If your timeline doesn’t leave room for years of diversifying, a concentrated client base doesn’t have to derail your plans. It just means your MSP exit planning needs to tackle it head-on, through deal structure, timing, or how you position the business to prospective buyers.
Some owners choose to delay the sale and diversify first. Others decide the value of moving now outweighs the cost of waiting, especially when market conditions are on their side. Either path can work, as long as it’s a deliberate choice, and not something you discover halfway through a negotiation.
Customer concentration can affect valuation, buyer interest, due diligence, and deal structure, so it should be considered alongside the wider strengths and risks of the business. Contract terms, customer tenure, renewal history, account ownership, and the quality of recurring revenue can all influence how a buyer interprets the risk.
The Host Broker can help you review these factors, anticipate the questions buyers are likely to raise, and get your MSP ready for sale. If customer concentration is part of your exit planning, get in touch to discuss your position and the best approach for bringing your MSP to market.
Buyers may start asking questions once one client accounts for 15% to 20% of monthly recurring revenue, with anything above 25% inviting closer scrutiny.
Losing one dominant client after closing could significantly reduce future revenue, so buyers price that risk into the deal through a lower multiple or additional deal protections.
It varies, though owners may see meaningful improvement within 12 to 18 months of focused client acquisition, depending on their sales cycle and market conditions.
Yes. Buyers usually review how much revenue depends on major accounts, along with contract strength, customer tenure, and the likelihood of retention after closing.
A high level of customer concentration may lead buyers to view future earnings as less predictable, which can influence the valuation multiple and deal terms.
