Before we get started…

If you're working harder than ever but your business still can't run (much less grow) without you, that's not a "you" problem…it's a systems problem.

We work with founders to build a custom "operating system" inside their business (the same process we've used to scale our own $200M portfolio) so the business can scale without the founder doing all the scaling.

Ok, back to this week's issue…

"Should I fire my best client?"

A few weeks ago, a business owner popped up on Reddit asking whether he should fire the client that pays half his bills.

The actual title of the thread: "Should I fire a client that's 50% of my revenue? Losing my mind here."

Did you catch that? He’s “losing his mind”…

…over his best client!?!

The internet, naturally, gave him unhelpful advice:

Half the comments said, "Fire them before they fire you."

The other half said, "Are you crazy? Serve them harder and pray."

Both camps missed the point (and the solution)…

There IS a fix for this, and I'm going to show you what it is in a minute. I’ll even give you a copy-paste AI prompt that runs the whole thing for you in about 60 seconds.

But before I give you the solution, we first need to discuss why customer concentration is such a problem for small businesses…

  • First, it hurts your valuation. Buyers get nervous when a single client climbs north of 20 – 25% of revenue, and most will discount hard or walk entirely. Nothing says "fragile" quite like one logo that can erase half the P&L with a single phone call.

  • Second, it hurts your negotiating power. You’ll tolerate scope creep, late invoices, and margin squeeze from a 50% client that you'd never tolerate from a 5% client.

  • Third (and this is the sneaky one), it hurts your judgment. Every strategic decision…new offers, pricing changes, who to hire… gets filtered through, "But what would [Whale] think?" You effectively abdicate control of your company to your largest account.

You own the business, but they own YOU.

The fix? It's called The Customer Concentration Audit. Here’s how it works…

Step 1: Divide the Pie

Rank every client by their percentage of your trailing 12-month revenue on a simple spreadsheet.

Not this month's revenue… trailing twelve, because whales are lumpy, and one big invoice (or one slow quarter) will lie to you.

Fair warning: the number is almost always worse than your gut is telling you it will be. The owner who guesses their top client is "maybe 20%" opens the spreadsheet and finds 38%.

Step 2: Find the Line

Now grade every slice of that pie:

  • Over 25% of revenue is a whale, because that's roughly where acquirers start discounting the price or walking away entirely (discounts of 15 – 30% are common when a single client crosses that line).

  • 10 – 25% is a watch-list client. We call them “baby whales” because they're one good year away from becoming a full-grown whale.

  • Under 10% is just a client. Congratulations, that's what they're supposed to look like.

One caveat: if you're in a vertical where concentration is structural (government contractors, enterprise services), the line moves, but the audit doesn't.

Buyers in those spaces underwrite contract terms and relationship depth instead…which is exactly what the next step covers.

Step 3: Run the Three P's on Every Whale

For every client over the line, you're going to check three boxes: Paper, People, and Pipeline.

Paper. Pull the contracts for each whale and baby whale and answer three questions:

  • What's the notice period?

  • When's the auto-renewal date?

  • Is there a termination-for-convenience clause (the clause that lets them quit any time, for any reason)?

Most business owners open that contract and discover it only locks THEM in: the client can walk with 30 days' notice, but you've committed your pricing, your capacity, and your team for the full 12-month term.

Fix that asymmetry at the next renewal, and put the renewal date on your calendar so it doesn’t catch you off-guard.

People. Count the relationships. If the whale's business rests on ONE champion inside their org, then your revenue is really resting on that one person's job security.

Champions change jobs without warning, so assign someone (not you) to build a second and third relationship inside that account this quarter.

Pipeline. This is the one everybody skips, because it feels like a marketing project instead of a risk project.

Here's the move: leave the whale alone and grow everything around it.

Set one number…"By [date], no client exceeds X% of revenue"…then reallocate marketing spend and sales attention until the math works. The whale stays the same size. The pie gets bigger.

I call it dilution by growth, and it's the only version of this fix that doesn't cost you a dollar of revenue.

And if you're thinking, "But my whale is a GREAT client"…perfect. Nothing in this system asks you to serve them less. It just makes their departure survivable.

Great clients respect vendors who don't need them, and desperate vendors get squeezed.

Step 4: Put It on the Calendar (and Let AI Run It)

Run this same ritual at the end of every quarter: rebuild the spreadsheet, recheck who’s above line, rerun the three P's on anyone over 25%… then 10%.

And put it on your calendar now, because if it’s not on the calendar, it’s not getting done.

Here's an AI prompt that automates most of this process. Just copy and paste it into Claude or ChatGPT, along with your client revenue list:

❝

Here is my client revenue for the trailing 12 months: [paste list].

Calculate each client's percentage of total revenue. Flag every client over 25% as HIGH concentration risk and every client between 10 – 25% as WATCH.

For each flagged client, build a de-risk checklist covering: (1) the contract notice periods and renewal dates I should verify, (2) relationship depth…how many contacts we have inside the account and who owns each one, and (3) a dilution target showing what total revenue growth would bring this client under 20% without losing a dollar of their business. Format it as a one-page brief.

So…back to our Reddit friend…

Should he fire the client that’s paying half his bills?

If they're toxic, sure. Fire away, and figure it out.

But if their only crime is being big, don't fire them…

…outgrow them.

⚡️ Action Step: Pull your trailing 12-month revenue by client and draw the pie…it takes 10 minutes. If anyone's over 25%, read their contract this week and find the notice-period asymmetry. Then set your dilution target ("no client over 20% by [date]") and reallocate your sales and marketing budget/resources to make it happen.

Give it a shot and let me know how it goes…

P.S. We help our clients de-risk issues like this all the time…client concentration, key-person dependence, founder dependence, all of it.

But here's the truth: if your business doesn't have the right systems in place, none of it matters. That's why the first thing we do with every client is install a custom "operating system" inside their business…so it runs (and grows, and becomes worth owning) without depending on you.
