They say that the pilot standing at the cabin door as you board isn't only being polite. Somewhere in that half-second of eye contact, they're reading the cabin — who's steady, who's anxious, who might become a problem at thirty thousand feet, and who they could count on if things went badly.
Whether that's true or not is up for debate, but to me it's still the best description of the first ninety days of a finance engagement. People expect the first month to be spreadsheets. It isn't. It's almost entirely conversations — and those conversations look like introductions while doing something rather more deliberate.
Who You Actually Talk To
The founder first, obviously, and any co-founders. But the conversations that change the picture are usually with employees three through twenty.
Those people are worth more than the org chart. They know how the business actually runs, as distinct from how it is described in a deck: which client always pays late and why everyone has quietly accepted it, which product takes three times the effort the price assumes, why the Tuesday report exists and who stopped reading it two years ago. They know where the workarounds are, because they built them.
You're mapping knowledge and reliability at the same time — who understands their own numbers, who's guessing, who will tell you something inconvenient and who will tell you what they think you'd like to hear. That last distinction matters more than any of the finance work that follows. Every number you'll eventually rely on was entered by somebody, and you need to know which somebodies.
What You're Mapping
The output of those weeks is a set of process flows: how revenue actually arrives, and how money actually leaves.
Note that neither of those is a finance question. Revenue starts in sales and marketing, gets shaped by pricing and delivery, and depends on operations doing what was promised. Costs start with headcount decisions, vendor choices and how the work is scheduled. Strategy sets the direction all of it runs in. HR determines who's in which seat and what they cost.
So the mapping covers all of it — operations, sales and marketing, strategy, even HR — and none of that is a detour from the finance work. It is the finance work, done properly.
Why Finance Is the Best Seat in the House
Here's the thing that took me years inside larger businesses to appreciate properly.
Every physical and digital interaction in a company eventually arrives as a number. A customer complaint becomes a credit note. A rushed hire becomes payroll, then overtime, then a recruitment fee when it doesn't work. A vague scope becomes unbilled hours. A promise made in a sales call becomes a delivery cost somebody has to absorb.
Finance sits downstream of all of it. That makes it the only chair in the building with a view of every function at once — not the deepest view of any one of them, but the only complete one. An operations lead sees operations superbly. A sales director sees the pipeline. Finance sees what each of those decisions actually did.
That vantage point is the product. Everything else in the first ninety days is a consequence of using it.
What Lands in the First Ninety Days
Four things, near enough every time.
A rebuilt general ledger and chart of accounts. Unglamorous and non-negotiable. Most SME charts of accounts were set up years ago by somebody optimising for statutory filing, not for understanding a business. They group things that should be separate and separate things that belong together, which is why the P&L can be technically correct and still tell you nothing. Rebuilding it is the difference between a report and an answer.
A dashboard that works — and the order matters here. A dashboard is a quick win because the chart of accounts underneath it now means something. Built the other way round, on inputs nobody trusts, it doesn't give you insight; it gives you the same confusion, faster and in colour. The first version is deliberately modest, and it keeps improving as the understanding of the business deepens. A dashboard that stops changing is usually one that stopped being read.
A working grasp of the business drivers. Not metrics — drivers. The two or three things that, when they move, drag everything else with them. Most businesses have fewer than people assume, and most founders can name them within an hour of being asked the right questions. They just haven't been asked.
An indicative rebuilt budget. Not a comprehensive one — that comes later and takes longer. This is a first pass, triangulated from what the conversations turned up and from historical revenue and opex trends. Its job isn't precision. Its job is to steer the conversation in the right direction: to give everyone a shared set of numbers to argue about, so the arguments are about the business rather than about whose spreadsheet is right.
The Part That Actually Changes Things
Underneath all four sits the work nobody puts on a proposal: data governance and sanitisation. Deciding what gets recorded, by whom, in what form, and cleaning up what's already there.
It is genuinely tedious, and it is the whole game. At the end of ninety days the deliverable isn't a chart of accounts or a dashboard. It's that the founder trusts the figures.
That changes how decisions get made, and it's worth being precise about how. Most founders of good businesses run on instinct, and their instinct is usually excellent — it's what got them here, and it reads a customer or a market faster than any model. The point was never to replace it. The point is that instinct now has something to check itself against.
You still make the call. But you make it knowing that the sense you have about the second location is supported by the numbers rather than contradicted by them — or, occasionally, that it isn't, and the number is telling you something your gut hadn't caught yet. That's not a smaller role for instinct. It's a better-informed one.
The aim was never to replace your instinct. It was to give it a second opinion you can trust.
What It Isn't
There's no sixty-page report at day ninety. Nobody restructures anything in month one. And nobody should be promising you savings before the numbers are reliable enough to prove they happened — a saving you can't evidence is a story, not a result.
What it needs from you is fairly specific and worth knowing upfront: access to systems, time with your people, and honest answers to some awkward questions. The last one costs nothing and is the one most likely to be withheld. If a business hides its mess in the first month, it just pays to have it discovered in the fourth.
Which brings it back to the aeroplane. The conversations are polite, and they're genuinely friendly, and they are also an assessment — of the business, its numbers, and who can be counted on when something goes wrong.
The difference is that here, everyone knows that's what's happening. That's what the first conversation is for.
