Every SME owner has taken a deal they shouldn't have. Not because the client was difficult or the margin was thin — because saying yes felt safer than saying no. If you're chasing every dollar of revenue that walks through the door regardless of fit, you don't have a growth strategy. You have a collection plate. The businesses that break through $2M, $5M and $10M in revenue aren't the ones that say yes to everything — they're the ones with a filter for what they say no to, and the discipline to use it before the contract is signed, not after the client turns into a nightmare.

The enemy here isn't greed — it's a quiet belief almost every founder carries: that turning down revenue is irresponsible. It feels like leaving money on the table. But every deal you accept consumes capacity — your best people's time, your cash flow, your attention — and that capacity is finite. When you say yes to a client who doesn't fit your ideal customer profile, pays late, demands constant customisation, or drags your average margin down, you are not adding to the business. You are trading capacity you could have spent on a better-fit customer for capacity spent managing a worse one.

Customer profitability research keeps finding the same shape, industry after industry: a meaningful slice of any company's customer base is quietly unprofitable once you count the true cost of servicing them — the extra support hours, the rushed jobs, the discounts negotiated under pressure. Harvard Business Review's work on strategic planning makes the same point from a different angle: strategy is fundamentally about choosing what not to do. A growth roadmap without a "no" list isn't a strategy. It's a wish list with a sales target attached.

Here's the tool Kevin uses with clients before any deal above a threshold that matters to their business — for most SMEs, that's anything that would take up more than 10% of a month's capacity. Four questions, answered honestly, before you sign anything:

1. Margin fit — Does this deal sit at or above your average margin, once you honestly cost the time it will take? If it's below, you need a specific reason it's worth it (strategic logo, entry into a new channel) — not just "revenue is revenue."

2. Capacity fit — Who does this actually take off other work, and what does that other work stop happening? Name the person and the task. If you can't, you haven't costed it properly.

3. Direction fit — Does saying yes pull you toward the business you're trying to build in three years, or does it pull you sideways into a business you didn't choose?

4. Precedent fit — If you say yes to this, what does it train your next ten prospects to expect from you? One bespoke exception becomes the new normal faster than owners think.

A deal that fails two or more of these isn't automatically dead — but it needs a deliberate decision from you, not a default yes because the number looked good in the moment.

"Kevin's knowledge and intellect on all things business — no matter what industry it is — he just seems to find gems that you can focus on. I catch up with Kevin once a week and it is definitely the highlight of my week. He just sees different opportunities so clearly. I would not have considered the B2C market as an opportunity before working with Kevin and now it is a major focus for us. He has opened up so many new opportunities for us."

Most owners Kevin works with can recite this logic back to him perfectly. They still say yes. The real obstacle isn't understanding — it's that saying no to revenue, in the moment, feels like admitting the business isn't strong enough to be selective. It's an ego problem wearing a cash-flow costume. Add to that the absence of anyone in the room asking the four questions out loud before the deal is signed, and the default wins by default.

This is precisely where an outside voice earns its place — not to tell you what to do, but to force the fit filter onto the table before the signature, when a founder on their own will talk themselves into "it'll be fine." A structured second opinion, applied consistently, is worth more to your margin than almost any single piece of new business you could chase.

If your growth plan is really just "say yes to everything and hope it adds up," that's the first thing Kevin fixes with you.

...and you become the owner who says yes to the deals that fit and no to the ones that don't.
