Hire a Financial Controller when the problem is control, accuracy and the close. Hire a Head of Finance when the problem is direction, planning and the layer of judgement that sits between you and the numbers.
Those two sentences solve most of the confusion, but the titles blur in practice, and the wrong choice costs you a year. So let's make the distinction real.
What does a Financial Controller actually own?
A Financial Controller owns the integrity of your numbers. The month end close, the reconciliations, the ledgers, the audit, the compliance, the controls that stop small errors becoming big ones.
They run the transactional team below them. They make the close faster and cleaner. They are the person who can tell you, with confidence, that the figure is right.
A strong Controller frees up your week by taking ownership of everything that has to be correct. You stop checking journals. You stop chasing reconciliations. You stop being the last line of defence on accuracy.
What a Controller does not typically own is the forward view. They report what happened. They are less often the person building the three year plan or challenging the commercial assumptions behind next year's budget.
What does a Head of Finance actually own?
A Head of Finance owns the picture, not just the ledger. They sit closer to strategy, planning and the story the numbers tell.
They usually carry FP&A, business partnering and the narrative that goes to you and, through you, to the board. They connect the accounting to the decisions.
Crucially, a Head of Finance can act as your deputy. They can take a meeting you cannot. They can hold a view on pricing, margin or investment and defend it.
Many strong Heads of Finance still expect solid control underneath them, but they are not the person you hire to fix a broken close. You hire them to lift the function's thinking.
Which one does your function actually need right now?
Start with where the pain is, not the title you fancy.
If your reporting is late, your audit is painful, your controls are thin or your transactional team lacks a leader, you need a Controller. That is a control problem, and no amount of strategic polish fixes it.
If your numbers are accurate but your planning is weak, if you are the only person who can interpret the business, if you cannot delegate the forward view, you need a Head of Finance. That is a leadership and insight gap.
Ask yourself a blunt question. What is currently landing on your desk that should not be? If it is accuracy and process, hire down into control. If it is judgement and planning, hire the layer directly below you.
Can one person be both?
In smaller businesses, yes, and often the title becomes Financial Controller with strategic scope, or Head of Finance with hands on control duties. That works while the business is simple enough for one person to hold both.
The trouble comes when you stretch one hire across both worlds and expect brilliance at each. Detailed, controls minded people and big picture, commercially minded people are not the same profile, and pretending otherwise leads to a hire who is average at both.
Be honest about which half matters more over the next eighteen months. Hire clearly for that, and support the weaker half with your own time or a capable number two.
How do you sequence the two hires as you grow?
Most functions build control first, then insight. You get the close clean and the team stable under a Controller, then you add planning firepower with a Head of Finance or a Head of FP&A above or alongside them.
Occasionally you reverse it. If your accounting is outsourced and reliable but you have no one to think, a Head of Finance comes first and control follows.
Either way, name the roles properly when you advertise them. A mislabelled brief attracts the wrong shortlist and wastes weeks. If you want a second view on the level and the market rate, that is exactly the kind of thing we help finance leaders get right at Harper May, and you can see current mandates on our live roles.
What does the wrong hire look like in practice?
A services business we spoke to hired a Head of Finance because the CFO wanted a strategic partner. Six months in, the close was still late and the audit was still messy, because the real gap had been control all along.
They had bought vision when they needed rigour. The fix was a Controller underneath, and only then did the Head of Finance role start to pay off.
The lesson is simple. Diagnose the gap before you write the title.
Common questions
Does a Head of Finance sit above a Financial Controller?
Often, yes, in a larger function the Controller reports into the Head of Finance. In a smaller one they are alternative titles for the senior hire below you, so judge by scope, not label.
Which hire frees up my week faster?
A Controller, if your time is going on accuracy and process. A Head of Finance, if your time is going on planning and interpretation. Match the hire to where your hours actually leak.
What if I genuinely need both?
Hire the more urgent gap first, usually control, then add the second within twelve to eighteen months rather than asking one person to excel at both.
