Quick test for CMOs: name your top 3 internal relationships.
CEO and CRO are obvious. ✅
If CFO isn’t on the list, it should be.
Here’s why a CFO relationship belongs in the top 3:
- The CFO controls marketing’s operating reality
Headcount, agencies, tools, events, programs, contractors. You can have the right strategy and still be blocked if finance doesn’t trust how you spend, forecast, and make tradeoffs.
- The CFO is a powerful ally in the boardroom
In many companies the CFO is one of the most trusted voices with the CEO and the board. When they understand your model and believe you run marketing with discipline, that support matters in rooms you’re not in.
- In good quarters, a strong CFO helps you scale faster
The best CFOs aren’t “budget police.” They think like operators. When things are working, they’ll often be the strongest internal advocate for reinvesting.
- In bad quarters, finance influences what gets cut and what gets protected
When targets are missed, marketing becomes an easy place to blame and cut. If finance trusts you, and understands your assumptions and leading indicators, the conversation is much more likely to be “how do we adjust” than “what do we slash.”
So how do you actually build that relationship before you need it?
Here are my four tips for a healthy CMO-CFO relationship
- Start in annual planning, not in a crisis
Be a real partner in the budget build. Even if you get a top-down target and a budget range, bring a bottom-up, zero-based plan: channels, costs, expected output, assumptions. It’s much easier to earn trust when you show up with a strategy and a model, not a last-minute request.
- Agree on the tracking structure before money starts moving
How spend is categorized becomes how it’s evaluated. Align early on buckets (field, digital, events, brand, etc.) so your reporting reflects how you actually operate, especially for big items like conferences.
- Create a monthly operating rhythm with finance
Set a monthly 1:1, ideally week 3 after month’s end, and use it to review budget vs actuals (BvA) for the month, QTD, and YTD.
- Treat the CFO like a strategic peer, not a spreadsheet gatekeeper
In your 1:1s, don’t just review spend. Pull them into the strategy: how your ICP is evolving, what you’re betting on, what you’re deprioritizing, and why. If a conference is a big line item, explain it like you would to the CEO: for this ICP, this is the must-attend room, and here’s why it’s worth it.
The best finance leaders want that context, and they’re absolutely capable of engaging at that level.
The CMO-CFO relationship is critical and you can’t build it on demand. If the only time finance hears from marketing is when you need approval, you’re already late. Build the rhythm early, while things are calm, and you’ll feel the difference the first time they aren’t.
