The CFO is in the marketing meeting now. Good.

Finance scrutiny of marketing spend has gone from annual to constant. The CMOs who treat that as an opportunity are winning budget. The ones who treat it as an intrusion are losing it.

For most of my career, marketing budgets were set once a year in a negotiation with finance and then defended, more or less, until the next one. That has changed. The CFO now wants to see the return on every major line, every quarter, and sometimes every month.

Some marketing leaders resent this. I think it is the best thing that has happened to the function in a decade.

Why

Money that cannot be explained gets cut. Money that can be explained gets protected, and often increased. The CMOs who can show the CFO exactly what the agency fee buys, what the media supply chain costs, what production returns, and how the technology stack earns its keep are the ones whose budgets survive a bad quarter.

That means treating marketing as a cost base with the same discipline finance applies to everything else. Benchmarked fees. Contracts with audit rights. Media measured on outcomes rather than impressions. A technology inventory that matches licences to users.

The uncomfortable part

Most marketing organizations cannot do this today. Not because they are careless, but because commercial governance was never their job and nobody built the capability. Procurement helps with the paperwork and stops at the door of the creative relationship.

So the CFO asks a fair question, the CMO does not have the number, and the conversation becomes adversarial. Both sides lose.

What good looks like

A marketing leader walks into the finance review with a one-page view of the cost base: agencies, media, production, technology, team. Each line benchmarked. Each line with an owner and a plan. The savings from last quarter's renegotiation flowing back into media that performs.

The CFO stops asking whether marketing is efficient and starts asking how much more it can do. That is the conversation you want.
