EP302 - Why Your Biggest Client Could Be Your Biggest Problem with Ian Luckett

In this episode of The IT Experts Podcast, I want to talk about one of the most common reasons MSP owners end up coming to the Growth Hub for help, and it is one I wish more people addressed before it becomes a crisis. That dreaded phone call. Your biggest client rings up and tells you they have been bought out, they are in financial difficulty, or they are simply leaving. If you are lucky, you have a three year contract in place. If you are not, you could lose that revenue overnight. This is client concentration risk in its rawest form, and it catches so many MSP owners completely off guard.

Client concentration risk builds quietly. On paper, your revenue looks healthy because your biggest client keeps growing with you. Underneath that growth, your exposure is increasing every month. Your costs stay fixed while your income becomes tied to the decisions of one organisation you do not control. When that client leaves, the cash flow shock is sudden, staff redundancies can become a real possibility, and instead of planning for growth you are firefighting to survive.

I want to share the five steps we walk our own clients through in the Growth Hub to manage client concentration risk properly, and I would love for you to take action on these today rather than filing them away for later.

The first step is to calculate the revenue percentage contributed by your top ten clients. Many owners only look at their bank balance and assume everything is fine. A healthy bank balance tells you nothing about debtors, accruals, or how exposed you really are. Once you know the numbers, you can start making informed decisions rather than hopeful ones.

The second step is to stress test what would happen if you lost your largest client tomorrow. Look at your contract length, whether that is thirty days or five years, and talk this through with your team. Bringing your help desk and wider team into this conversation matters, because client concentration risk should never sit with the owner alone.

The third step is to build and maintain a rolling ninety day cash flow forecast. This single habit gives you far more clarity than watching your bank balance ever will. It shows you your reserves, your incoming recurring revenue, and your project work, so you can make confident decisions around recruitment and resourcing rather than reactive ones.

The fourth step is to set a target to reduce dependency on any single client over time. If your biggest client currently represents fifty percent of turnover, aim to bring that down gradually, perhaps to forty percent next year and thirty the year after. Best practice suggests no single client should represent more than ten percent of turnover for a strong business valuation, and closing that gap steadily protects you from client concentration risk without damaging the relationship with that client.

The fifth and hardest step is strengthening what we call your new client runway, so you consistently replace revenue rather than relying on one relationship to carry the business. Account management keeps your existing clients happy, and it needs pairing with sales and marketing activity that brings in fresh leads every single month. We call this ONCA, one new client a month. Build credibility with your target market, stay consistent on your messaging, and bring your existing clients into events where they can introduce people who are not yet clients.

Reducing client concentration risk gives you a more resilient business. Your valuation improves, your cash flow forecasting becomes sharper, and your leadership time shifts from firefighting back into planning for growth. No MSP owner wants that call from their biggest client to be the moment they finally address this, so I would encourage you to run these five steps this week with your team.
