Moving from Practice to In-House Finance

Moving from practice to in-house is the most common career transition in the qualified finance market. Every year, thousands of ACA and ACCA-qualified accountants who trained in Big Four, mid-tier or regional practices make the decision to leave the firm environment and move into an in-house finance role at a commercial business. Most of them make the move within two to four years of qualifying. Most of them find the transition straightforward. But there are specific dimensions of the in-house environment that practice-trained accountants consistently underestimate, and getting these right in the first six months of the new role is what determines whether the transition is a successful launch into a strong in-house career or a slow-start that takes longer than it should to recover.

This guide is written for ACA or ACCA-qualified accountants who are planning or considering the practice-to-in-house move — covering what the in-house role involves that practice does not, what roles to target first, how to negotiate the salary step, and the most common mistakes practice-trained candidates make in the first three months.

What Practice Gives You That In-House Doesn’t

Practice training provides three capabilities that are genuinely valuable and that most purely in-house trained accountants lack. The first is breadth of statutory exposure — having seen dozens of finance functions from the outside, through audit fieldwork and accounts review, gives you a comparative perspective on what good looks like that a finance professional who has only ever worked inside one business cannot develop at the same speed.

The second is technical depth in financial reporting. The ACA and ACCA practice training routes develop a level of technical accounting rigour — the ability to research and apply accounting standards, to identify and document complex accounting issues, to produce statutory accounts to a standard that survives external audit scrutiny — that the management accounting focused training routes develop less systematically. This technical depth is the primary reason practice-trained accountants are sought at Financial Accountant, Group FC and FC level in businesses with complex statutory reporting requirements.

The third is professional discipline. The practice environment — with its client deadlines, its billing pressure, its file review standards and its regulatory obligations — develops a level of professional rigour and work ethic that not every in-house training environment replicates. Most partners and hiring managers at commercial businesses who trained in practice themselves will tell you that practice training is the hardest professional discipline they experienced, and they value it in the candidates they hire because of what it signals.

What Practice Does Not Give You

The practice environment does not give you day-to-day management accounting experience. It gives you the ability to review and audit management accounts produced by others, but it does not give you the experience of sitting down on the first of the month and owning the close process — posting the journals, chasing the sales figures, running the payroll reconciliation, preparing the accruals schedule. Practice-trained accountants who move directly into Financial Controller roles at small businesses where they are expected to own the full close process, without the management accounting foundation that an CIMA or in-house ACCA-trained candidate develops as a matter of course, frequently find the first month-end more demanding than they expected.

Practice also does not give you the commercial engagement skills that the best in-house finance roles require. In practice, your clients pay you for technical accuracy and professional advice. In an in-house commercial role, your internal clients — the CEO, the operations director, the sales team — want you to understand their business and engage with their commercial problems. This requires a different mode of engagement than professional advisory work, and it takes most practice-trained accountants six to twelve months to develop it comfortably.

Be honest with yourself about these gaps. Most experienced hiring managers in the in-house market understand the practice-to-in-house transition profile well. They are not expecting you to have three years of management accounting experience alongside your practice training. They are expecting you to acknowledge the gap, articulate how you plan to close it, and demonstrate the self-awareness to know what you know and what you need to learn.

Which In-House Roles to Target First

The most natural first in-house role for a practice-trained ACA or ACCA candidate with two to four years of PQE is Financial Accountant or Financial Controller, not Management Accountant or Finance Business Partner. This reflects the alignment between what practice training develops — statutory reporting, audit management, technical accounting — and what these roles require.

At Financial Accountant level, the expectation is that you can own the year-end process, manage the audit and prepare or oversee the preparation of statutory accounts — all of which you have done in practice. The management accounting elements of the role — the monthly close, the management accounts — can be learned alongside these statutory responsibilities, typically with support from the FC or FM above you.

The Financial Controller route is appropriate if you are three or more years post-qualification, have managed clients through complex year-ends including multi-entity or IFRS reporting, and can credibly take accountability for a full finance function. Businesses that are specifically looking for a first FC — someone to build the finance function of a growing business that does not have one — are particularly suited to practice-trained candidates because the statutory foundation, the systems awareness and the professional rigour the practice training develops are directly applicable to this context. See the First Financial Controller guide for more on this specific role context.

The Salary Step: What to Expect

The salary step from practice to in-house is one of the most variable in the qualified finance market, because it depends heavily on the size of the firm you are leaving, the level you are at in the firm, and the in-house role and business you are moving to. As a broad benchmark for London in 2025: a newly qualified ACA at a Big Four firm earning £52,000–£58,000 should typically be targeting £55,000–£65,000 for a Financial Accountant or first Financial Controller role in-house. A Senior or Manager at a mid-tier firm with three to four years of PQE and a track record of leading client year-ends should be targeting £65,000–£78,000 for an FC or Senior FA role.

Do not undervalue yourself by assuming the in-house market will discount your practice experience relative to in-house candidates of equivalent PQE. In most cases the market pays a premium for the practice foundation, particularly where the in-house role has significant statutory complexity. See the London FC Salary Guide and the Financial Accountant Salary Guide for the current market benchmarks.

The First Three Months: Common Mistakes

The most common mistake practice-trained candidates make in the first three months of an in-house role is trying to apply the practice approach to the in-house environment. In practice, you investigate, document and report. In-house, you manage, decide and act. The in-house CEO does not want an audit file — they want a clear, concise view of the financial position and a recommendation for what to do about it. Calibrating your communication style from advisory and documented to direct and commercial is the most important adjustment practice-trained candidates need to make.

The second mistake is underinvesting in relationship-building with the operational team. In practice, your relationship with the client is the engagement. In-house, your relationship with the operations, sales and commercial teams — the people whose P&L you are managing and whose decisions you are expected to support with financial analysis — is the foundation of your commercial effectiveness. Practice-trained accountants who focus exclusively on the technical finance work in their first three months and do not invest time in understanding the operations team, their language and their problems, consistently take longer to add commercial value than those who invest in those relationships from day one.
