Your Head of FP&A should not report into your Financial Controller. They do fundamentally different jobs, they optimise for different things, and folding one under the other quietly weakens both.
That is the short answer. The rest of this is why it happens, what it costs you, and how to structure the layer below you instead.
What is the actual difference between these two roles?
Your Financial Controller owns the truth of what happened. Close, controls, reconciliations, statutory accounts, audit. Their job is accuracy, completeness, and a clean set of books that stands up to scrutiny.
Your Head of FP&A owns the story of what happens next. Forecasting, budgeting, commercial analysis, scenario work, the numbers that shape decisions before they are made.
One looks backwards and closes the door. The other looks forwards and keeps it open. Both are essential. Neither is senior to the other by nature.
So why do so many teams stack FP&A under the Controller?
Usually history, not design.
The Controller was often the first proper finance hire. As the team grew, analysis work appeared and got handed to whoever had capacity. FP&A emerged underneath the control function almost by accident, and nobody ever went back to question it.
It also feels tidy on an org chart. One person to manage, one number to your desk. But tidy and effective are not the same thing.
What does it actually cost you when FP&A reports into control?
Three things, and you feel all of them eventually.
First, priority conflict. When close and forecasting collide, control always wins under a Controller. It has to. Audit deadlines and statutory dates are non negotiable. So the forward looking work gets bumped, quietly, month after month, and you wonder why your forecasting never quite matures.
Second, mindset dilution. Great FP&A needs someone who challenges the business, sits in commercial conversations, and is comfortable with assumptions and ambiguity. A control led culture rewards precision and caution. Those are the right instincts for the ledger and the wrong ones for a five year model. Put FP&A under control and you slowly train the challenge out of it.
Third, career ceiling. Your best FP&A person will not stay to be a sub function of accounting. They want a seat, a voice, and a line to you. If the only route up runs through the Controller, they leave. Then you are hiring again, which is the expensive way to run a team.
Does this mean the two functions should not talk?
No, the opposite. They should be joined at the hip.
FP&A depends on the Controller for clean actuals. The Controller benefits from FP&A flagging where the business is heading so close holds no surprises. The point is not separation, it is parity. Two strong functions that collaborate as equals, both reporting to you.
What you want to avoid is a hierarchy where one owns the other. Collaboration between peers is healthy. Subordination is where the analysis quietly dies.
What should the structure below you actually look like?
In most mid sized and scaling businesses, both your Financial Controller and your Head of FP&A report directly to you.
The Controller carries the transactional and technical team beneath them. Financial accountants, the close, accounts payable and receivable, the machinery that produces reliable numbers.
The Head of FP&A carries the analysis and partnering layer. FP&A managers, analysts, the people embedded with commercial teams.
That gives you two clear pillars, one for accuracy and one for insight, and it frees up your week because you are no longer the only person doing forward looking thinking. You are also building two credible successors rather than one, which matters more than most leaders admit until they want to move.
If you are weighing up whether you need both roles yet, or how to sequence the hires, that is a conversation worth having properly. It is the kind of structural work we do with finance leaders every week at Harper May.
When is it acceptable for FP&A to sit under control?
Genuinely early stage, when you cannot justify two senior salaries and one strong all rounder covers both. That is fine, and common.
The mistake is leaving that structure in place long after the business has outgrown it. Once forecasting drives real decisions and the board expects proper scenario work, FP&A needs its own line and its own leader. If you are recruiting for either pillar, our live finance roles show what strong candidates in this market look like.
Common questions
Can one person really cover both Controller and FP&A?
Early on, yes, and many do it well. But it is a stopgap. The skill sets diverge as you scale, and the person strong at both is rare and quickly stretched. Plan for the split before you are forced into it.
My Controller is more commercial than my FP&A lead. Should they run it?
Then you may have the wrong FP&A lead, not the wrong structure. Reporting lines should reflect the role, not the individual. Fix the hire rather than bending the org chart around it.
How do I split them without bruising egos?
Frame it as growth, not demotion. You are giving both functions the room and the profile to do their best work. Bring both into the conversation, be clear on remit, and most people welcome the clarity.
