The skill nobody starts with
When I wrote about my first two years, I listed "saying yes to everything in year one" as something I got half wrong. Two years further on, I'd go further: learning what to decline has done more for the quality of this practice than anything I've learned about growth marketing in the same period.
That's an uncomfortable sentence to write, because it sounds like the kind of thing consultants say once they're comfortable enough to be picky. So let me be specific about what I decline, why, and what it actually costs.
The four I now decline reliably
1. The engagement with no owner.
A company wants growth help, but nobody internally owns the outcome. The founder is interested, marketing is under-resourced, sales reports elsewhere, and no single person's quarter depends on this working.
These engagements produce good work that goes nowhere. The recommendations are accepted, nobody is accountable for implementing them, and six months later the situation is unchanged. I now ask directly: whose objectives does this sit inside? If the answer is vague, I decline.
2. The problem that isn't a marketing problem.
Retention is bad because the product doesn't deliver. Pricing is wrong for the segment. There's no product-market fit and demand generation is being asked to compensate.
More acquisition makes all of these worse — faster, and more expensively. I'll say this in the first conversation, and occasionally it turns into a different, better engagement. Usually it ends the conversation, and it should.
3. Validation dressed as analysis.
The decision is made. What's wanted is an external name attached to it, usually for a board.
The tell is in how past attempts get described — every one was undermined by someone else, never by the plan. If I take these, one of two things happens: I confirm the decision and I've sold my judgement, or I contradict it and the work is shelved. Neither is worth doing.
4. The fit I already know is wrong.
Enterprise-only, sales-led, in a category I don't understand, at a stage where my experience doesn't apply. I know within twenty minutes. I used to take these anyway when the pipeline looked thin.
The two I took in year one both cost more than they paid. Not just in time — in the confidence damage of doing mediocre work, which took longer to recover from than the money did.
What saying no actually costs
I want to be honest about this, because the standard version of this advice is written by people whose pipelines are full.
It costs real revenue, at the worst possible times. The pressure to say yes is highest in a thin quarter, which is exactly when the decision matters most and is hardest to make. I've turned down work in a month where I needed it, and the following six weeks were genuinely uncomfortable.
It doesn't always pay off. The narrative version says declining bad work creates space for better work. Sometimes it creates space. I've had quarters where I said no to two poor fits and nothing arrived to replace them.
I still think it was right — but "trust that better work will appear" is a claim I can't actually support with evidence, and I'd rather say that than pretend the maths always works.
The ones I still get wrong
Scope creep in good engagements. I'm fine at declining bad engagements at the start. I'm much worse at holding a boundary six months into work I enjoy, with a client I like, when the request is reasonable and adjacent. The cumulative drift is real and I don't have it solved.
Saying no to the interesting-but-wrong. Problems I find genuinely fascinating in categories where I'm not the right person. My judgement is worst precisely where my curiosity is highest.
Timing. I decline too late. The information that tells me to say no is usually available in the first conversation, and I've more than once let a proposal process run because I didn't want to end a conversation that was going well.
The reframe that made it easier
For a long time I thought of declining as turning down money.
What changed it was noticing that a poor-fit engagement doesn't cost you the fee — it costs you the fee plus the three months of capacity plus the work you couldn't take plus the reference you don't get. The genuinely bad engagements in my first two years were negative on every axis except the invoice.
So the question I ask now isn't "can I do this?" It's: will this client be able to point at a result in six months?
If I can't see how, the answer is no, and the reason is usually something I can name in the first conversation if I'm willing to.
