You said yes again. Another enquiry that doesn't quite fit, another client who'll argue the quote, another project that'll eat your weekend for a margin that barely covers the diesel. You know this one won't be easy. You take it anyway, because turning down revenue feels like turning down the business itself.

Here's the question worth asking before you chase one more customer: do you actually know who you're trying to win? Not "anyone who'll pay" — the specific, nameable kind of customer your business is built to serve brilliantly. Most SME owners can't answer that in one sentence, and it's costing them more than the client who argues the quote.

In over 30 years working inside global agencies and founding nine companies of my own, the pattern repeats: businesses that try to be right for everyone end up being unforgettable to no one.

Growth advice usually starts and ends with volume — more leads, more enquiries, more yeses. Nobody tells you that saying yes to the wrong customer is a decision, made over and over, that quietly sets your strategy for you. Every client you accept who isn't a genuine fit teaches your business, your pricing and your team that this is the kind of work you do. You don't drift into being the business that attracts difficult, low-margin, energy-draining customers. You choose it, one enquiry at a time, by never choosing anything at all.

A.G. Lafley and Roger Martin, who led Procter and Gamble's turnaround, built their strategy process around one deceptively simple question that comes before any other: where will you play? Not every market, not every customer — the specific arena you can genuinely win in. Only once that's decided does "how to win" matter. Most SME strategic plans skip straight to tactics — ads, offers, hustle — without ever properly answering the first question.

I watched this choice change everything for a high-end jeweller I worked with. Her mission was deliberately audacious: Rihanna wearing one of her designs to the Met Gala. It sounds like vanity until you see what it actually did — it told her, instantly, which commissions were worth her time and which weren't. Within the year, Cardi B and Stephanie Seymour wore her pieces in Paris. That didn't happen because she said yes to more customers. It happened because she got brutally clear on which ones she was playing to win with.

Almost every owner I coach already knows, somewhere, which customers drain them. What stops them acting on it isn't ignorance — it's fear that saying no will leave a hole in the revenue nobody fills. That fear is solvable, but not by thinking harder about it alone. It's solved by building the pipeline and the pricing that make "no" safe to say, which is exactly the work a coach does alongside an owner, not instead of them.

This isn't for you if turning down revenue, even the bad kind, still feels impossible today. That's fine — it usually takes one real win with the right customer before "no" stops feeling like a loss.

If your calendar is full of customers who drain you instead of the ones who'd grow you, that's the first thing we fix.
