Marketers, Stop Trying to Out-Finance the CFO

Michael Baker-Mosley · 20 September 2026 · 3 min read

Somewhere along the way, marketers got it into their heads that the way to stay respected was to sound like finance.

We started parroting their language, building dashboards no one asked for, and trying to reverse engineer every action into a spreadsheet.

It has not worked.

You cannot out-finance the CFO.

Stop trying.

When we play that game, we lose the one advantage only marketing has: knowing the customer better than anyone else. If you give that up, you are not a marketer anymore. You are a junior analyst with worse Excel skills.

And honestly, "I am not a factory, I am trying to influence people" is closer to the truth than most marketing plans will admit. That is the work. Influence. Understanding. Taking the market's temperature before anyone else does. Not mass producing justification slides to appease a model no one believes anyway.

The irony is that CFOs do not want marketers to pretend to be finance. They already have finance. What they want is a marketer who understands the business and the customer, and who can clearly explain where demand will come from. Not someone performing attribution theatre with numbers measured to four decimal places.

The job you are not doing while you build the dashboard

Marketing's actual job is to know the market deeply. To see the shifts before the board notices. To spot the things customers want but have not said out loud yet. To tell uncomfortable truths, including when the product is not good enough. To align sales, product and leadership around reality rather than wishful thinking.

And when you spend all your time trying to prove short term return on every single activity, you stop doing the real work. You stop looking outward. You stop studying behaviour. You stop understanding why customers buy, why they do not, and what actually moves them.

You end up defending activity instead of creating demand.

That is the core mistake.

Marketing is not a cost centre to be justified. It is the function that protects the company from becoming irrelevant. That takes judgement. Pattern recognition. Instinct. Context. Conversation. All the things attribution software cannot see.

What AI did to this argument

Here is what has changed, and it has changed in marketing's favour, though not many people are behaving as if it has.

The measurement, reporting and analysis layer that marketers spent fifteen years using to justify their existence is now close to free. An AI tool will build the dashboard, run the analysis, write the summary and produce the board slide. Faster than you, and without the passive aggression.

Which means the work you were using to prove your value has just become the least valuable thing you do.

If your answer to "what does marketing contribute" was a set of reports, you are in trouble, because the reports no longer require you. If your answer is that you understand the market better than anyone else in the building, you are in an extremely strong position, because that still requires a human who has spent years paying attention.

Ironically, the CFO gets this before most marketers do. Finance has already worked out which parts of its own function compress and which do not. The parts that survive are the judgement calls. Same for us.

This is not permission to ignore the numbers

Let me be clear, because this argument gets misused by people who simply do not want to be measured.

You need to understand customer acquisition cost, lifetime value, margin and the commercial model. You need to know how the business makes money. You need to be able to sit in a room with the CFO and hold a conversation about payback periods without reaching for a colleague.

Commercial literacy is not optional. It is the entry requirement.

But there is a difference between being commercially literate and cosplaying as the finance team to prove your value. One earns you a seat. The other quietly confirms you did not deserve one.

Marketing creates leverage through customer understanding, not through out-analysing the analysts.

So stop trying to out-finance the CFO. They have got that covered.

Do the work they cannot do.

Own the customer.

Own the market.

Own the story.

That is where the power is.

A Head of Marketing, a Marketing Director, a CMO, or none of the above. The choice is not about titles. It is about ambition, investment and what your organisation can currently absorb.

There was never a sales versus marketing problem in B2B. Just two teams closest to the market, facing the same pressures, usually getting blamed for the same things.
