An ex-Big 4 accountant can be an excellent early finance hire, but the training is no guarantee. Most leave three to five years in, around qualification, and the first move usually comes with a pay rise. The ones who succeed in a startup are natural problem solvers who can handle ambiguity; the ones who struggle miss the structure and support they had. Test for that, not for the logo on the CV.
What Big 4 experience tells you, and what it does not
Someone who has done three or four years in a Big 4 firm has been trained hard. They know accounting standards, they have seen how large companies close their books and report, and they are used to long hours and demanding clients. If your problem is technical, such as getting audit-ready before a raise, that is real value.
What it does not tell you is how they work when nobody hands them a plan. Coming from a Big 4 firm, people are often sheltered: it is very structured, you get put in your stream and you follow along. The learning is great, but if something sits outside their scope of work, sometimes they just do not get it. When I compare them with people from a smaller investment house, the smaller-firm candidates usually understand the chaos and messiness of a small company better.
The CV can also flatter or undersell. Some people at a Big 4 firm only touch the surface of a big engagement; others are deeply involved in it. And a candidate without Big 4 on their CV can be in the top bracket for commerciality and the value they deliver. I think Big 4 experience is often overrated on a CV for exactly that reason.
| What Big 4 training gives you | What an early finance seat also needs | |
|---|---|---|
| Technical grounding | Accounting standards, audit and reporting to a high bar | The same, applied to messy data with no team to review it |
| Working environment | Structure, support, a defined stream of work | Ambiguity, changing priorities, building the process yourself |
| Scope | One part of a large client engagement | The whole finance function, plus legal, compliance and admin |
| What it proves | Capability and work ethic under pressure | Problem solving and adaptability, which you have to test for |
Why Big 4 accountants leave, and when
Most people leave the Big 4 three to five years in, when they hit their qualification. Big 4 is not for everyone, and so many people leave soon after qualifying because it is a full-on environment. My rough read is that most of a qualifying year moves on within two years. The result for founders is a steady supply of candidates every year.
The reasons they move matter when you are pitching your role. A lot of them got where they are because they are ambitious and want growth and development. Money plays a part too: leaving the Big 4 generally comes with a pay bump. If your role offers real growth and a bigger scope than they had, say so early; it is what most of them are moving for.
What an ex-Big 4 hire costs in Australia
For someone leaving a Big 4 firm at qualification, three to five years in, the first move is typically A$105,000 to A$115,000 plus super, depending on the role. That is broadly the same whether they come from audit, business advisory or M&A. That price buys a capable early team member in a reporting-focused role, usually sitting under a head of finance.
It does not buy a first finance hire. The person I place as a first head of finance or financial controller at late seed to Series A usually has several years in commercial roles behind them, and they cost more. For wider benchmarks on early team roles, see the senior accountant salary benchmarks and the financial accountant salary range pages.

When hiring from the Big 4 works
It can work brilliantly. One first finance hire I know came straight from audit, with no commercial or startup experience. That person built the finance function, set up the processes, raised capital and hired a team below them, and the business has grown fast since. People can do it. You just have to give them a go.
But that hire is more of the anomaly than the rule. Most founders do not want to take that leap on someone from a big-firm background, and they have reason: the amount of times where that hasn't worked out is way more than it has. Finding the one who can is a needle in a haystack, which is hard for a founder who does not come from finance.
The difference is approach and attitude. Some people from structured backgrounds are natural problem solvers, they adapt, and it works fine. The ones who already understand what they are walking into hit the ground running.
When it does not work
It fails when the person needs the structure they left behind. A lot of people coming out of the Big 4 are just not prepared for that level of grey and uncertainty, because startup land is that. It is chaos, and it is opportunity at the same time. The startup space looks appealing from the outside, and many finance people do not appreciate the grind until they are in it.
What to test for in a Big 4 candidate
Test for versatility, problem solving, willingness to learn, work ethic and adaptability. These are what I look for in any senior finance hire, and if someone ticks each of those boxes, it does not matter what industry they come from. Big 4 training does not tell you whether they have them.
Because so many people leave the Big 4 every year, the pool is big, and that makes filtering harder. You cannot tell from a CV which candidates are aligned to your business and actually want to stay. Ambitious people may give you 18 to 24 months before they want the next role. That is sometimes not the worst thing, because they tend to perform well in that time, but you should know it going in.
In the interview, get underneath the client names. When a candidate describes a big engagement, ask what they were doing specifically. That separates the people who were deeply involved from those who saw the surface. Build the rest of the process around a real problem in your business, as I set out in how to assess a head of finance or CFO.

Should "must have Big 4" be on your brief?
I would leave it off. It is a common request from hiring managers, especially for senior finance and financial reporting roles, and it shrinks the talent pool for little gain. In January 2025 I predicted the request would become far less common by the end of 2026, because the quality of work from firms outside of the Big 4 continues to rise and the gap is closing quickly.
Our own data shows how rarely the first finance hire comes straight from a Big 4 firm. Of the 191 first finance hires we traced at funded Australian startups, 4% (8 of 191) joined directly from a Big 4 firm. Ask for the problem solving and adaptability, and treat Big 4 training as a bonus rather than a filter.

Common questions
Is Big 4 experience necessary for a startup finance hire?
No. Big 4 training gives strong technical grounding, but the first finance hire in a startup succeeds on problem solving, adaptability and comfort with ambiguity. Plenty of excellent startup finance leaders trained in mid-tier firms, industry or other startups, and insisting on Big 4 experience shrinks the talent pool.
How much does an ex-Big 4 accountant cost in Australia?
Someone leaving a Big 4 firm at qualification, three to five years in, typically moves for A$105,000 to A$115,000 plus super, depending on the role. That is the price of an early team member such as a financial or senior accountant. A first head of finance or financial controller with commercial experience on top costs more.
Why do so many accountants leave the Big 4?
Most leave three to five years in, around the time they qualify. The environment is demanding, many are ambitious and want broader growth and development, and leaving usually brings a pay rise. That creates a steady supply of candidates every year.
Can someone straight from audit be a startup's first finance hire?
Yes, but it is the exception. Some people come straight from audit, build the finance function, raise capital and hire a team. More often it does not work, because the person misses the structure and support they had. If you take the chance, test hard for problem solving and how they handle uncertainty.
What should I test for when interviewing an ex-Big 4 candidate?
Test versatility, problem solving, willingness to learn, work ethic and adaptability. Ask what they did specifically on the engagements they list, so you can tell deep involvement from surface-level exposure, and use a case study built on a real problem in your business. Also ask why they are leaving and what they want next, since ambitious candidates may only stay 18 to 24 months.
