A new CFO or first finance hire should spend month one on questions, month two on diagnosis and month three on one visible change. The founder should judge that first quarter on control, not visible output, because most first hires walk into messy accounts and reporting.
What a first finance hire actually walks into
Start with the state of the books, because it decides what a realistic first quarter looks like. In our Q3 2026 State of the Market poll we asked first finance hires in our network what they most commonly walk into. 70.7% said messy accounts and reporting. Another 21.2% said there was no forecast or model at all. Cap table chaos was about 4%.[1]
Messy books are a cleanup. A missing forecast is the more strategic gap, because it means the business has been making decisions without a forward view. Either way, a clean set of books is the exception. For the new hire, that means pricing the cleanup into the first 90 days and sequencing accounts and reporting before anything forward-looking. For the founder, it means the first quarter should be judged on control, not on visible wins. If your finance leader spends ten weeks making the numbers reliable, that is the job, not a delay to it.
Before day one: the notice period is part of onboarding
At senior level, three months’ notice is normal, and the gap between signing and starting is where good hires go quiet. As I put it on Confessions of a Recruiter, “that period between resignation to start date” can be “an absolute horror show if you don’t do it right.” The onboarding checklist I give clients for it has four points, and none of them is expensive:
- At resignation and contract signing. The hiring manager reaches out personally to say congratulations and welcome. Not HR, not the recruiter. The person they will report to.
- About two weeks out. A coffee or a proper catch-up, in person if you can. Talk about the first week and the first month, and invite questions.
- The day before. Tell them what the first day looks like, who their buddy is, and make sure their logins and systems access actually work.
- Day one. Show them around, and have the people they will work with most in the room rather than working from home that day.
It works. On one placement the hiring manager called the candidate before their start date to talk through the first week and month and to invite questions, without being asked to, and the candidate started already impressed.[2] The notice period is also when a counter-offer lands. If your hire is sitting on unvested options or a bonus that pays out after their notice date, stay close to them until they start.
The offer and the resignation week have their own risks. I cover how to close a finance hire and handle the counter-offer.
Days 1 to 30: questions, not answers
The first 90 days in a new finance role are typically full of questions, because new hires notice manual reconciliations, disparate reports and processes nobody has questioned in years. That noticing is the new hire’s most valuable asset and it has a short shelf life. Write everything down in month one, because by month four it will look normal to you too. What the first 90 days should prove depends on which seat you are in.[3]
Spend the month on people and mechanics in parallel. Meet the CEO properly, then every executive peer, then your own team individually, then the auditor and the bank. On the mechanics side, sit through a close rather than reading about it.
Days 31 to 60: diagnose, and choose what not to fix
By the second month you will have more problems than capacity. The diagnostic list that matters is cash and runway accuracy, the close cycle, forecast credibility, controls and audit exposure, the systems estate, and the shape of the team. Expect the mess the poll describes, and sequence accounts and reporting before you build anything forward-looking.
The close is usually where the evidence is. For many finance functions a 12-day month-end close is due to manual data pulls from three different systems, reconciliation in Excel and reformatting for board reports. If that is your situation, you have found both the problem and the first credible win. Check the statutory side of the diagnostic against ASIC’s list of reporting obligations by entity type rather than against what the business has been doing, because those two diverge more often than founders expect.
| Where to look | What you are actually testing | |
|---|---|---|
| Cash and runway | The forecast, the bank, the payment terms | Whether the founder or CEO can state runway from memory and be right. If not, this is your first priority regardless of what else is broken. |
| The close | How many days, and how many people | How much of it is manual pulls across systems and reconciliation in Excel. Usually the clearest early win available. |
| Forecast credibility | Last three forecasts versus actuals | Whether anyone outside finance believes the numbers. A forecast nobody trusts is not a forecast. |
| Controls and audit | Prior year issues, delegations, approvals | What would be embarrassing in diligence. Find it before an investor does. |
| The team | Structure, capability, workload | Who is carrying work that should sit across several roles. Headcount cuts leave finance leaders absorbing it quietly. |
| Stakeholder read | What each executive wants from finance | Whether finance is currently seen as a partner or a blocker. That answer sets how fast you can move. |
Days 61 to 90: act, and be seen doing it
Pick a small number of visible changes and finish them. A useful benchmark for what is achievable: a Financial Projects Manager I placed at an international SaaS business built SOx process documentation from scratch in their first three months, giving the business structure, control and audit readiness. Three months is enough for one real structural thing, not five. In a startup the best choice is usually a control win the founder feels: a faster close, or a cash forecast they can finally trust.
A live example of a low-cost win: an Australian scale-up controller uses AI to refresh their board pack every Monday with a single instruction, then checks revenue, cash and ARR against Xero and adds commentary, which removes the manual rebuild entirely. Keep the governance rule attached to it. AI produces a first draft, not a final answer, and a qualified person checks every number and signs off anything that reaches a board, investor, auditor, client or regulator. Our guide to getting started with AI in finance has more workflows that fit inside a first quarter.
The founder’s side of the 30/60/90
A founder who has just signed a finance leader usually has one question: how will I know it is working before there is much to see? The honest answer is that the first quarter produces understanding and control before it produces output. The clearest single test comes from the same Q3 report. If you still cannot explain, this month, the difference between your cash position and your profit, that is the first thing your finance hire should give you, and a fair way to judge whether the hire is working.
| What they should be doing | What you should see, and the red flag | |
|---|---|---|
| Days 1 to 30 | Meeting you, the executive team, the bookkeeper or outsourced accountant, the auditor and the bank. Sitting through a close. Asking a lot of questions. | A written list of what they have found, and more questions than answers. You should be spending real time with them this month. Red flag: a restructure or a new system proposed in week two, before they have seen a close. |
| Days 31 to 60 | Diagnosing cash and runway, the close, the forecast and controls, and deciding what not to fix this year. | A runway number you both believe, and a short, ordered list of what they will fix first, starting with accounts and reporting. Red flag: building a sophisticated model on top of books that do not reconcile yet. |
| Days 61 to 90 | Finishing one or two changes the business can see, usually a faster close or a cash forecast that holds. | You can explain the gap between cash and profit this month, and the board pack or investor update is built by them, not by you. Red flag: five initiatives started and none finished, or the operations team still working around finance rather than with it. |
One signal comes later and is worth waiting for. A good finance hire often brings their network with them: I regularly see a new finance leader introduce the founder to someone they worked with at their last business, that person gets hired and performs, and the finance hire’s credibility goes up again. That tends to happen around six months in, not in the first quarter, so do not read anything into its absence at day 90.
For what the role should have built by the end of the first year, not just the first quarter, I set out what a CFO does in a startup, and what the first finance hire builds in year one.
The thing that actually decides it
Numbers matter, but trust matters more, because without it even the best reporting will not get used. The temptation in a new senior finance role is to dive straight into quick wins and efficiency fixes. The first 90 days are not only about quick wins; they are about building trust. A gun CFO put it well: teams do not care what you say, they watch what you do, and trust in finance leadership is earned when teams see you step up and roll your sleeves up alongside them. In the first quarter that usually means being visibly present through a close rather than announcing a target operating model.
The consequence of getting it wrong is fast. I had a conversation with a CFO about a Head of Finance hire who left within nine months despite strong qualifications, because they could not win the CEO’s trust or build rapport with Operations. When trust does land, finance stops being a blocker or a silo and becomes a partner the business leans on for clear advice and commercial support.
The CEO relationship carries more weight than anything else in this window. I set out how the two seats actually work together.
If it is your first CFO seat
Two things are worth knowing before you start. A first CFO role gained through internal promotion is very different to moving across businesses and being hired as a new CFO. Internally you arrive with relationships and no honeymoon; externally you have goodwill and no context. The plan should be different in each case.
The self-doubt is normal. Most senior finance leaders carry a version of it internally and few say it out loud. On The CFO Track, one CFO described taking the seat while doubting their technical skills, having never been a group financial controller. Get a mentor in place before day one rather than in month five.
On mentoring and the other development routes that actually work for finance leaders, I weigh them up here.
Common questions
What should a CFO do in their first 90 days?
Roughly: listen in month one, diagnose in month two, act visibly in month three. Spend the first meeting the CEO, the executive peers, your team, the auditor and the bank, and sitting through a close rather than reading about it. Use the second to run a diagnostic across cash and runway, the close cycle, forecast credibility, controls, systems and the team. Finish one or two real changes in the third, rather than starting five.
As a founder, how do I know my new finance hire is working in the first 90 days?
Judge the first quarter on control, not visible output. By day 90 you should have a runway number you trust, a short ordered list of what they are fixing, and a clear explanation of the gap between your cash position and your profit. In Story Recruitment's Q3 2026 poll of its network, 70.7% of first finance hires said they walk into messy accounts and reporting, so time spent making the numbers reliable is the job, not a delay to it.
What should a founder do between signing a finance hire and their start date?
Treat the notice period as the start of onboarding. Three months' notice is normal at senior level. Have the hiring manager reach out personally at resignation, organise a coffee about two weeks before the start date to talk through the first week and month, tell them what day one looks like and who their buddy is the day before, and make sure the people they will work with most are in the office on day one. Stay close to them: the notice period is when a counter-offer lands.
What is the biggest mistake a new CFO makes in the first quarter?
Leading with a restructure or a target operating model before they have earned the right to. Numbers matter, but trust matters more, because without it even the best reporting will not get used. Teams do not care what you say, they watch what you do, and trust is earned when they see you step up and work alongside them. I have seen a strongly qualified finance leader leave within nine months because they could not win the CEO's trust or build rapport with Operations.
Is the first 90 days different for an internally promoted CFO?
Yes, considerably. A first CFO role gained through internal promotion is a very different job to moving across businesses and being hired as a new CFO. Internally you arrive with relationships and history but no honeymoon, and the challenge is re-contracting how people see you. Externally you get goodwill and a clean slate but no context, so the listening phase has to be genuine rather than performative.
