Finance feels like overhead right up until it becomes a problem. That is why the first finance hire usually happens later than it should, and why it usually happens under pressure.
Pressure produces a predictable result. You hire someone good at month-end. Strong on process, comfortable in the accounts, reliable on the close. All of that is correct, and none of it is what you actually needed.
Two different skills wearing one job title
Closing the books and reading the numbers are not the same skill.
One tells you what happened. The other tells you what to do about it. Most growing businesses need the second one first, and most only work that out a year after the hire is made.
The instinct is right about the work and wrong about the order
Most people who think they need a CFO need a financial manager first. Somebody to run the close, own the ledger, keep the filings clean, and stop you doing any of it at the weekend.
That is the right read of the workload. It is the wrong read of the order.
What happens when the order is wrong
Hire the financial manager first and they will build what they know: compliance, and a clean record of what already happened. The month will close on time. The accounts will be tidy. Nothing will look wrong.
And the way your numbers are set up will be blind to what is coming, because nobody asked what decisions you would be making in three years before deciding what to record today.
By the time you are raising money, defending a margin, or answering questions in a sale process, the way your numbers are organised is working against you. What follows is not a tidy-up. It is a second build, and it lands when you have least room for it.
The order that works
Design first. What decisions are coming, what you will need to know to make them, and what that means for what gets recorded today.
Build second. The financial manager implements that specific design rather than a generic one.
Improve third, using the same judgement to turn clean numbers into better decisions.
CFO-level judgement bookends the process. The financial manager sits in the middle. Getting that the wrong way round is what buys you the rebuild.
This is not an argument for a full-time CFO.
Design is not a full-time job. It is a few days of senior judgement at the right moment, and then somebody who keeps checking that what got built still answers the questions you are asking.
What you need at that point is not a permanent CFO salary. It is one person accountable for the whole of the finance side of your business, doing as much of the day-to-day as the business actually needs.
Three questions that place you on the timeline
If you asked for gross margin by product line this afternoon, would you have an answer today, and would you trust it?
Does anybody own the question of what your numbers should be able to answer two years from now?
When something in the accounts looks wrong, does one person get to the bottom of it, or does it get passed around until it stops being urgent?
A no to the first means the hire is overdue. A no to the second means the hire is about to be the wrong one. A no to the third means you may already have the people, and nobody owning them.
Two costs. Only one is avoidable.
Hiring late costs you a year of decisions made without the numbers. That is expensive, and it is hard to avoid entirely, because the trigger is usually growth nobody scheduled.
Hiring in the wrong order costs you a finance function that has to be taken apart and rebuilt exactly when you have become too busy to survive it. That one is avoidable. What avoids it is somebody with CFO-level judgement owning the design before the advert goes out, and staying accountable for it afterwards.
