First 90 Days in a New Finance Role: NQ to Manager

The first ninety days in a new finance role at newly qualified to manager level are different from arriving as a Finance Director, and most advice on the subject is written for the latter. You are not setting direction or building a mandate; you are proving you can be relied on. Nobody hands you authority, and the credibility you will need later is earned in the first three months by doing unglamorous things well. This guide covers what to do in weeks one to twelve, what to notice, and the mistakes that cost people credibility they then spend a year rebuilding. (If you are arriving at director level, our guide to the Finance Director’s first 100 days covers that quite different job.)

It applies whether you are a newly qualified ACA, ACCA or CIMA taking your first industry role, a management or financial accountant moving to a larger business, or a Finance Manager stepping into a new function. The roles differ, but the pattern is the same: understand first, deliver reliably second, improve third. If you have just made the move from practice, our guide to moving from practice to industry as a newly qualified accountant covers the adjustment in more detail.

Weeks 1–2: understand the plumbing

Resist the temptation to have opinions. In the first fortnight your job is to understand how money actually moves through this business and where the numbers come from.

Follow a transaction end to end. One sale from order to cash, one purchase from requisition to payment. It teaches you more about the business, the systems and the controls than a week of reading procedures — and it surfaces the workarounds nobody mentions.

Get the last three months’ management accounts and the last statutory accounts (the filed version is public at Companies House), and read them properly. Then ask someone to explain the three things you did not understand. Asking well-formed questions in week two builds more credibility than pretending in week ten. If the difference between the two sets of numbers is unclear, our explainer on management accounts versus statutory accounts is a useful refresher.

Meet your immediate colleagues individually, including the transactional team. In most finance functions the person who processes the purchase ledger knows where the problems are, and they will tell someone who asks.

And learn the close timetable — not the published version, the real one. Which days are pressured, what always arrives late, who chases whom.

Two practical points are worth adding. Sort out your system access in the first few days — ERP, reporting tools, bank portals, shared drives — because a missing permission discovered on working day two of the close is an avoidable problem. And keep a running notebook from day one: names, systems, account codes, recurring journals and the questions you have not yet had answered.

Weeks 3–6: deliver your first cycle

The first month-end is the moment your reputation is set, and the standard to aim for is unremarkable: on time, accurate, no surprises.

Prepare more than you think you need to. First closes take longer because nothing is where you expect it. Start earlier, and ask before you guess.

Flag problems early rather than solving them silently. A number that will not reconcile, raised on day three, is a shared problem. Raised on day eight, it is your problem. Nobody minds a new joiner asking; everyone minds a surprise.

Do not change anything yet. You will see things done inefficiently — a spreadsheet that should be a report, a reconciliation done twice. Note them. Suggesting improvements in month one, before you understand why it is done that way, is the fastest way to be marked as someone who does not listen. Some of those workarounds exist for reasons that will only become apparent at year-end.

And write down what you learn. The accrual bases, the odd account, the supplier who always disputes. You will be the person who knows this in a year; capture it while it is still surprising.

For the mechanics of a well-run close — timetables, reconciliations, review points — see our guide to optimising month-end close. Read it for context, not as a list of changes to propose in your first month.

Weeks 7–12: earn the right to improve

Once you have delivered two clean cycles, you have credibility to spend. Spend it carefully.

Pick one improvement, not five. Something visible, bounded and useful — a reconciliation that can be automated, a report that takes four hours and could take one, a control gap that matters. Deliver it completely.

Frame it as a question rather than a criticism. “I noticed the bank rec takes half a day — would it help if I looked at whether the feed could be improved?” lands very differently from “this is inefficient”. The second is frequently true and rarely effective.

Understand who your work serves. If you produce a pack, find out who reads it and what they do with it. Analysts who know the answer to that produce different work from those who do not — and it is the habit that separates the people who progress from the people who do not. Our guide to management reporting that gets read develops the point.

And ask for feedback explicitly at the ninety-day mark, rather than waiting for a probation review. “What would you like me to do differently?” asked directly usually produces something more useful than any formal process.

What to notice while you settle

Four things worth forming a view on quietly during the first quarter, because they shape what your next two years look like.

Is the balance sheet actually reconciled? The single best indicator of the state of a finance function, and the thing most likely to become your problem at year-end.

Does the business act on the numbers? If the pack is produced and nothing changes, you are in a production role regardless of the job title.

Who is respected, and why? Finance functions have informal authority structures that rarely match the org chart.

And is anyone developing you? At this level, a manager who reviews your work and explains their thinking is worth more than a salary difference — and CPD obligations through ICAEW, ACCA or CIMA continue regardless. If nobody is, that is information — and worth raising before it becomes a reason to leave.

The mistakes that cost credibility

Comparing everything to your last employer. “At my old firm we did it this way” is the most common and most damaging habit of new joiners. Even when you are right, it lands as criticism from someone who does not yet understand the business.

Guessing rather than asking. A wrong number delivered confidently costs far more than a question asked in week three.

Going quiet when struggling. The instinct is to work harder alone. The people who settle well ask earlier than feels comfortable.

Over-promising in month one. Taking on extra work to make an impression, then delivering the core role late.

And treating the transactional team as beneath you. Newly qualified accountants sometimes do this without noticing. It is both unpleasant and self-defeating — those colleagues determine whether your close runs smoothly.

If it is your first management role

One additional dimension. If the move also brings direct reports for the first time, the ninety-day priority is different: understand what each person actually does before changing anything about how they do it. Sit with them. Learn their bottlenecks. The instinct of a newly promoted manager is to demonstrate value through change, and the effect is usually to disrupt work that was functioning while missing what genuinely needed attention. Our guides to Management Accountant versus Finance Manager and the FM to FC step cover what the ownership dimension actually requires.

Agree how you will review work, hold a short one-to-one with each person in the first fortnight, and be clear about what will not change while you learn. People in a team that has just acquired a new manager mostly want to know whether their jobs are about to be disrupted; answering that early buys you the time to understand the function properly.

A 30, 60 and 90 day plan at a glance

The same sequence, condensed into a plan you can adapt. The milestones are a guide rather than a deadline; in a business with a quarterly or complex close, the timetable will stretch.

Building relationships outside finance

At newly qualified to manager level, the relationships that matter most outside the finance team are usually with the people who generate the transactions and the people who consume your reports: operations, sales administration, payroll or HR, and the budget holders whose variances you will be explaining. Ask to spend half an hour with each in the first six weeks. Ask what they need from finance and what frustrates them about it.

This is where business partnering starts, long before the job title includes it. Budget holders who understand why you are asking a question answer it faster, and an accountant who understands the operation produces commentary that people actually read. Our guide to business partnering for management accountants covers how that develops.

Probation: what is really being assessed

Most finance roles at this level carry a probationary period, commonly three to six months; the terms are in your contract, and Acas publishes guidance on how probation usually works. In practice, a probation review in a finance function asks a short list of questions: is the work accurate, is it on time, does this person raise problems early, and do colleagues find them easy to work with?

Technical brilliance rarely decides it. Reliability and judgement do. If you have followed the sequence above — understood before acting, delivered two clean closes, asked for feedback before the formal review — the probation meeting should contain no surprises. If you are unsure where you stand at the halfway point, ask. A manager who has concerns would much rather discuss them in month two than in month six.

Quick wins that do not cost credibility

There are a few things a new joiner can do early that help without implying criticism of anyone:

• Clear an old reconciling item or aged query that nobody has had time to chase.
• Write up a procedure note for your area where none exists — useful for you and for whoever covers your holiday.
• Answer budget holders’ questions quickly and accurately, and follow up when you said you would.
• Tidy your own working papers so the reviewer can follow them without asking.
• Prepare early for the next audit or year-end request in your area, if the timing falls within your first quarter.

None of these changes anyone else’s process, and all of them make you easier to rely on.

The pattern behind people who settle well

The new joiners who settle best at this level are the ones who spend their first month being genuinely curious and their second month being reliable, and who leave the improvements until month three. The ones who struggle are almost always the ones who arrived with opinions — usually correct opinions, about a process that was indeed inefficient — and offered them before anyone had reason to listen. Credibility in a finance function is earned by delivering two clean closes, not by identifying problems. Do that first, and you will find people ask for your view rather than resisting it. And write everything down in the first fortnight: the things that surprise you now are the things you will have stopped noticing within a few months.

If the role is not what you expected

Sometimes the first ninety days reveal a genuine mismatch: the scope is narrower than described, the function is in worse shape than anyone admitted, or the development you were promised is not there. Give it a fair chance first — the early weeks in any finance role are the hardest, and many concerns resolve once you have delivered a couple of cycles. Raise specific issues with your manager before drawing conclusions.

If the problem persists, think carefully about timing rather than reacting. Our guide to when to change finance jobs covers the signals that a move is genuinely due, the situations where staying is the better choice, and how short tenures read on a CV.

Arriving at Financial Controller level instead

The principles carry upwards, but the emphasis changes. A Financial Controller is expected to form a view of the whole function within weeks, own the balance sheet and the audit relationship, and report on the state of finance to the leadership team. For that step, see our guides to a fractional Financial Controller’s first 90 days, moving from Finance Manager to Financial Controller and how the FC role changes as a business grows.

Frequently asked questions

How soon should I suggest improvements in a new finance role?

Usually after you have delivered two clean month-end cycles — roughly weeks seven to twelve. Note ideas from day one, but hold them until you understand why things are done the way they are.

What matters most in my first month-end?

Being on time, accurate and free of surprises. Start earlier than you think you need to, and raise anything that will not reconcile as soon as you find it.

How do I pass probation in a finance role?

Deliver accurate work on time, flag problems early, work well with colleagues, and ask for feedback before the formal review so there are no surprises on either side.

Is the first 90 days different for a newly qualified accountant?

The sequence is the same, but a newly qualified accountant moving from practice also has to learn how an industry finance function works — a recurring close, budget holders and internal customers rather than client deadlines. Asking questions early matters even more.

What if I realise in the first few months that the role is wrong for me?

Raise specific concerns with your manager first. If they cannot be resolved, plan a move carefully rather than leaving abruptly; our recruitment team can talk through options confidentially on 0204 553 8893.
