Every sales leader wants a top performer. Of course you do.

The problem starts when one person becomes so important that the business stops building anything around them.

They have the biggest accounts and know the customers better than anyone else. They know the pricing history, internal politics, and exactly who to call when something gets stuck. 

When an important deal comes up, everyone looks at them, which is great when everything is going well.

But ask yourself what happens if that person isn’t there.

Maybe they leave or take another job. Maybe they move into a different role, are out for three months for a reason nobody could have predicted, or take a permanent vacation in Fiji. 

How much of your revenue would suddenly become harder to protect?

That isn’t the salesperson’s fault, it’s an organizational risk.

How Companies Accidentally Create This

Nobody decides to build a company around one person, it usually happens one reasonable decision at a time.

They close the biggest account, so they keep the biggest account. They know the customer best, so nobody else gets introduced. They don’t like updating the CRM, so someone else handles it. They’re trusted with the complicated deals, so the complicated deals keep going to them. Each decision makes sense on its own.

If you do that for a few years, important relationships, account knowledge, and revenue can end up sitting with one person.

That might not seem like a problem while they’re hitting quota and keeping customers happy. But if they leave or become unavailable, the rest of the team may be left trying to piece together account histories, rebuild relationships, and figure out what happens next.

That’s when a top performer can become a single point of failure. The issue isn’t that they’re too good at their job. It’s that too much of what they know hasn’t been shared with the rest of the team.

Look At Concentration, Not Just Quota

Most sales teams track quota attainment, pipeline, conversion rates, and deal size. Those numbers matter, but they don’t tell you how much of the business depends on one person.

Start by looking at the last 12 months of closed revenue by rep. Then look beyond the numbers.

Who owns the major accounts? Who has the relationships? Who knows the history of the opportunities that are still open?

If your top salesperson were unavailable for 90 days or left the company, could another rep step into those conversations without the client feeling like they’d suddenly lost their main contact?

If the answer is no, you’ve found the problem before it becomes an emergency.

You’re not holding your best people back.

Make sure that’s clear. Your best salesperson should be paid well, trusted, and have room to grow.

The answer isn’t taking their accounts away just to make the numbers look more balanced. The answer is making sure the value they create becomes part of the company instead of staying in their head.

Someone besides them should be able to sit in on important account meetings. Account history should be in the CRM and decisions should make sense to more than one person. The team should understand what makes those big deals work.

Your top salesperson shouldn’t become less important.The company should become stronger because they’re there.

Build The Backup Before You Need It

Start with the important accounts. Introduce another person before there’s a reason to.

Look at the knowledge, deal history, contacts, decisions, objections, next steps, and account strategy. This should be accessible to the team.

Now build a bench. That doesn’t necessarily mean hiring someone immediately. It means giving other reps exposure to larger accounts, letting them listen in on important calls, and gradually giving them more responsibility.

The best time to prepare is when things are going well, or at least steady. Once the resignation email arrives, you’re already playing catch-up.

One Question Worth Asking This Week

Pick your top one or two sales people and imagine they give notice on Monday.

Who owns their five biggest accounts on Tuesday?

Who knows what’s happening in their open deals?

Who knows why those customers buy from you?

Who can make the next call without the customer feeling like the relationship just changed overnight, leaving them feeling confused. 

If the answer is mostly, “we will deal with that when it happens” or “we’ll figure it out,” that’s useful information.

Don’t worry, you don’t have to panic or fix everything at once, but now you at least know where the risk is.

The first step is recognizing that a strong sales organization doesn’t depend on one hero. It learns from its best people and turns that knowledge into something the whole business can use.
