Forecasting and strategic planning aren’t entirely CFO-level tasks, but they are very much CFO-level conversations. There’s a real and important distinction between owning the strategic questions that forecasting answers and building the analytical infrastructure that makes those conversations possible. Conflating the two is one of the most common ways growing companies end up with a CFO who is perpetually behind on everything. The best structure sees a CFO and an FP&A Manager working together – the former takes on strategic interpretation, while the latter acts as the analytical layer that makes that possible. Let’s break down the scope of forecasting and strategic planning in a growing company’s finance function, and who should own what.
A CFO owns the strategic interpretation of the financial forecast:
These are judgment calls that require experience, business context, and the ability to communicate complex financial trade-offs to a board or leadership team. They can’t be handed off to someone else. They’re also nearly impossible to do well if the CFO is simultaneously building the forecast from scratch every month, which is exactly the trap many lean finance teams fall into without realizing it.
An FP&A Manager owns the analytical infrastructure that makes the CFO’s strategic work possible. In practice, that covers a lot of ground:
When this layer is working, the CFO receives a complete analytical package – model updated against actuals, scenarios built, key variances explained – and spends their time on interpretation rather than construction. Finance operations research shows that CFOs supported by a dedicated FP&A function spend an average of 40% more time on strategic work than those managing the FP&A function themselves. That shift is the direct output of making the hire.
The most common point of confusion is scenario planning. Building scenarios, including selecting the variables, stress-testing the assumptions, and running the numbers across different growth paths, is FP&A Manager work. Deciding which scenarios to prioritize, what they mean for capital strategy, and how to present them to the board – that’s CFO work.
The same logic applies to budget process management. Coordinating inputs, driving the calendar, and consolidating the plan belong to the FP&A Manager. Signing off on the final plan and presenting it to investors belongs to the CFO. The two roles work in sequence: the FP&A Manager produces the analytical foundation, and the CFO builds the strategic narrative on top of it. Problems tend to surface when either person is doing the other’s job.
For companies working with fractional CFOs, this distinction matters even more. A fractional CFO is already capacity-constrained by design, working across multiple clients and engaged at a strategic level rather than an operational one. An FP&A Manager dramatically increases the leverage of that arrangement.
The fractional CFO directs the planning work, reviews outputs, and drives the strategic conversation. The FP&A Manager handles the modeling, coordination, and analysis that the CFO’s available hours simply don’t accommodate. Without that analytical layer underneath, fractional CFO arrangements tend to underperform – not because the CFO isn’t capable, but because there aren’t enough hours in the week.
FP&A Managers in MAVI’s network average 6-8+ years of experience and are familiar with different CFO environments, including fractional ones: managing planning processes independently, keeping analytical work moving without constant direction, and integrating into the CFO’s decision-making workflow without needing to be managed themselves.
The clearest signal that the FP&A Manager and CFO relationship is functioning well: the CFO is never surprised by the numbers. They know what the forecast says before a board meeting. They’ve reviewed the variance analysis before the close package goes out. They have scenario outputs ready when leadership asks a strategic question.
None of that happens when the CFO is building everything themselves. It happens when there’s an FP&A Manager who treats the analytical infrastructure as their core responsibility – and the CFO can trust the work is already done when they need it. MAVI can help you find an FP&A Manager who can build the analytical foundation of your finance function. Our pre-vetted network of global finance and accounting professionals includes FP&A professionals with 5-10+ years of experience, ready to integrate into your team in as fast as five days from discovery to onboarding.

Typically, the CFO owns board presentations: the narrative, the strategic implications, and the Q&A. An FP&A Manager may present operational details to operating or finance committees, but board-level communication is almost always the CFO’s role. The FP&A Manager’s job is to prepare the materials that make that presentation possible.
The process and mechanics, yes; the sign-off and strategic framing, no. An FP&A Manager should be able to run the full AOP cycle – building the model, coordinating departmental inputs, consolidating the plan, and delivering a complete package for CFO review. The CFO then adjusts for strategic priorities and owns the final plan. The two steps are distinct and both matter.
It means maintaining the financial model against monthly actuals, running quarterly re-forecast cycles with updated assumptions, producing scenario analyses when strategic questions come up, and delivering variance reporting that explains why performance diverged from plan. It’s a continuous operational responsibility, not something that happens once a year and gets filed away.
MAVI can place an FP&A Manager into your team in as fast as a week. Most then integrate effectively within two weeks – getting into financial systems, understanding the business model, and starting to take ownership of the planning cadence. The pre-vetting process specifically evaluates their ability to operate in lean, high-expectation environments without needing to be walked through every step, significantly pulling down ramp time.
