We love picturing finance as the strict gatekeeper watching every euro the marketing team spends. Ever since the word “performance” took over every meeting, plenty of marketing leaders feel like a controller is permanently leaning over their shoulder. A survey conducted by Bain & Company over more than 1,400 senior marketing and finance leaders with in depth interviews with twenty CMOs and twenty CFOs, shows that the CMO CFO relationship is far less adversarial than we tend to assume. The core issue is a language problem, and language problems can be fixed fast.

Marketing and finance want the same things

The first surprise is that both camps want to track roughly the same numbers. Return on investment, revenue growth, sales, customer acquisition, on those structural KPIs, the alignment already exists.

The paradox is that neither side believes it. In the interviews, CFOs and CMOs voiced the same worry, that they probably had the wrong objectives, when in fact they were chasing identical ones. Some sectors keep their favorite metrics, like cost of acquisition in banking or margin per deal in software. But two indicators show up everywhere, in every industry: sales and new customer acquisition. No need to invent shared goals, but just to talk better about the ones that already exist. That reframing is exactly what leading firms mean when they treat marketing as a driver of customer centric, sustainable growth rather than a cost line to defend.

Too much story, not enough proof

For years, marketing leaders have been told to become better storytellers in front of finance. The survey argues the exact opposite, when asked, finance executives almost unanimously want the CMO to leave the storyteller costume at the door the moment a budget conversation begins.

That nuance matters for anyone trying to strengthen the CMO CFO relationship. A finance leader does not want to wait for the ending to find out whether a campaign worked. They want to jump straight to the table that answers one question: did this deliver the result we agreed on, yes or no. The CMO can absolutely add a few highlights and a bit of context, but the conclusion has to come first.

One CFO at a major consumer goods group put it plainly: if marketing brought him data he could believe in, he would invest without hesitation, because his own interest is for the company to grow. The idea of a finance function that blocks on principle is largely false: finance is willing to believe in marketing, as long as the way you measure marketing performance and present it earns that trust.

Finance understands marketing but doesn’t trust the measurement

Another counterintuitive finding: finance leaders grasp far more marketing concepts than we give them credit for. Aided awareness, unaided awareness, pre and post campaign measurement, most of the CFOs interviewed understood these ideas perfectly well.

The friction sits in how much they trust the measurement. Most marketing results shown today do not map cleanly to a company’s ultimate goal, which is revenue and revenue growth. Tellingly, CFOs care surprisingly little about the details of the marketing mix. What they want is a readable link between the euro invested and the business result. When a marketing team walks in proudly announcing it “scored on brand,” while finance had no idea brand was the target for the period, frustration follows instantly.

This is where AI starts to make a real difference. The most advanced teams use it to connect data sources that used to sit in silos and to tie marketing activity to overall business outcomes. Connecting spend to revenue in this way is the whole point of modern marketing mix modeling, which increasingly lets CMOs and CFOs move in tandem instead of negotiating across a wall. The best operators push their data straight into finance systems, all the way through to sales. That ability to align marketing and finance in one continuous flow is quickly separating leaders from followers.

Build the measurement framework before you launch

If there is one reflex to take away from the whole study, it’s this one: finance leaders want marketing to co create the measurement framework up front, before a campaign even launches.

That means settling in advance on what you are trying to achieve and which indicators will decide it. Is this a year of winning new customers or a year of retention? Do we settle the campaign on brand or on sales? Several CFOs admitted suspecting some CMOs of not actually executing the company strategy, optimizing for brand when leadership was talking about loyalty, or the reverse. A marketing budget defended with a shared measurement framework gets approved far more easily than one justified after the fact with a slick deck.

Good news along the way: finance is more patient with brand investment than most marketers assume, provided expectations are set and agreed from the start. A CFO knows a brand investment will not turn into sales next week. On that point, the CMO CFO relationship gains enormously from formalizing the expected return windows, exactly the way a rigorous partner would when running a revenue focused acquisition strategy.

Trust is the foundation of the CMO CFO relationship

If all this sounds like finance encroaching on marketing with guardrails, the opposite is true. What CFOs really don’t want is to write the marketing strategy in the CMO’s place. Their job, they say with real nuance, is to allocate the company’s capital. Running marketing is someone else’s job, they want to know the strategy, not steer it, they want to manage the money, not the campaigns.

One sentence captures the finance mindset toward marketing: I don’t think about marketing any differently from any other function, it simply has to live within its budget. That is not hostility or contempt, it’s the same expectation applied everywhere else.

One blind spot remains, one the study itself regrets not digging into: how the C-suite perceives marketing. The CMO is still the easiest executive to let go when sales disappoint, often because leadership thinks short term while brands are built over time. A credible marketing ROI, backed by numbers shared with finance, is probably the best protection against that reflex.

FAQ

How do you improve the CMO CFO relationship in a small business?

Start by co creating a measurement framework before every campaign, agreeing on two or three KPIs tied to revenue. Then present results by leading with the number, before any context. That discipline alone often builds trust, even in a small structure where marketing and finance may sit with just two people.

Why do CFOs distrust marketing metrics?

It is not that they fail to understand them. The Bain research shows they grasp aided and unaided awareness and pre and post campaign measurement. The problem is that these metrics rarely connect clearly to revenue. Without a readable link between spend and business result, finance hesitates to invest, not on principle but for lack of proof.

Should marketers really stop storytelling with finance?

Yes, specifically inside a budget meeting. CFOs want the numbers first and a clear answer to the question of whether it worked. Storytelling keeps all its value in external communication and creative work, but it has to come after the data when you are defending a marketing budget or measuring marketing performance.

What role does AI play in aligning marketing and finance?

AI mainly helps connect previously isolated data sources and tie marketing activity to overall business outcomes. The most advanced teams push their data straight into finance systems, all the way to sales. That ability to align marketing and finance in one continuous flow is becoming a genuine differentiator.

Which KPIs do marketing and finance actually agree on?

According to the survey, sales and new customer acquisition top the list across every industry, alongside return on investment and revenue growth. Some sectors add specific metrics like cost of acquisition or margin per deal, but the common core almost always exists.
