Public Practice and Professional Services

Public practice accountancy refers to accountancy and professional services delivered by accounting firms to clients — audit, tax, advisory, outsourced finance — as distinct from in-house or industry accounting where the accountant works as an employee of a non-accountancy business. The distinction matters professionally because the training, qualification pathway, skillset and career trajectory of the public practice accountant is different in important ways from that of the in-house accountant, even where both hold the same professional qualification.

Accountancy Capital operates at the intersection of public practice and in-house finance. We recruit qualified professionals into in-house finance roles at £50,000 and above — with particular expertise in placing ACA-qualified practice leavers into Financial Controller, Financial Accountant and Finance Director roles in industry — and we recruit for senior qualified roles within public practice firms where the appointment requires a specialist mid-career or senior qualified candidate.

What Is Public Practice?

Public practice refers to the work done by an accountancy firm for external clients rather than for the firm itself. The term ‘in public practice’ describes an accountant who works for an audit firm, a tax practice, an advisory firm or an outsourced accounting provider and delivers professional accountancy services to a portfolio of business clients. This is contrasted with ‘in industry’ or ‘in commerce’, which describes an accountant employed directly by a non-accountancy business to manage that business’s own finance function.

The public practice professional is trained to serve multiple clients across different industries, business sizes and accounting contexts simultaneously. The in-house professional develops deep expertise in one business’s financial management over an extended period. Both tracks lead to full professional qualification — the ACA qualification is typically achieved in public practice; the ACCA is frequently completed in both practice and industry; the CIMA is almost exclusively an industry qualification — but the post-qualification careers of practice and industry professionals diverge significantly.

The major public practice firms — Big Four (Deloitte, PwC, EY, KPMG), Top 10 (Grant Thornton, BDO, Mazars, Forvis Mazars, Smith & Williamson) and the broader Top 50 network of regional and national accountancy firms — provide the training infrastructure for most of the ACA-qualified professionals who subsequently move into senior in-house finance roles. Understanding the public practice training background — what an ACA trainee at a Big Four firm is trained to do, what they are not trained to do, and how that translates into in-house value — is one of the most useful pieces of market knowledge an employer considering a practice-leaver hire can have.

What Public Practice Trains Accountants to Do

An ACA-qualified professional leaving public practice after two to four years of post-qualification experience typically has strong capability in the following areas:

Financial reporting standards. The practice environment requires constant application of FRS 102, IFRS and the related standards across a diverse client portfolio. The practice leaver’s technical accounting knowledge is typically more comprehensive and more current than that of an in-house accountant who has applied the same accounting treatments to the same business for several years.

Audit methodology and process. The practice-trained professional understands the audit process from the auditor’s side — which makes them exceptionally well-equipped to manage the audit from the in-house side once they move to industry. In-house financial accountants and FCs with practice backgrounds consistently manage audits more efficiently and with better auditor relationships than those without.

Cross-sector commercial awareness. The practice professional who has audited businesses across five or six different sectors has a breadth of commercial and financial context that the purely in-house accountant typically does not develop until much later in their career.

Technical documentation and professional discipline. Practice training is methodical, documented and quality-controlled. The practice leaver brings a professional discipline in workpaper quality, documentation standards and technical accounting memo writing that in-house training environments rarely replicate at the same standard.

What Practice Does Not Train Accountants to Do

There are important in-house capabilities that practice training does not develop well, and that the practice leaver needs to build after moving to industry:

Month-end close management. Practice accountants produce statutory accounts, not management accounts. The month-end close process — posting journals, managing close schedules, producing timely management accounts — is an in-house skill that most practice leavers have limited direct experience of before their first in-house role.

Commercial business partnering. Practice professionals advise on financial matters but typically do not sit in the business and challenge commercial decisions in real time. The business partnering dimension of in-house finance — attending operational team meetings, providing financial challenge to commercial decisions as they are being made — is a capability that most practice leavers develop in their first in-house role rather than arriving with.

Financial systems and ERP management. Practice firms use audit software. In-house finance runs on ERP systems, accounting packages and reporting tools that practice professionals have limited exposure to. The practice leaver’s first in-house role typically involves a system learning curve that experienced in-house candidates have already passed.

Moving from Public Practice to In-House Finance

The transition from public practice to in-house finance — the ‘move to industry’ — is one of the most significant career decisions an ACA or ACCA-qualified professional makes, and one where the timing, the first role choice and the employer type all have a significant influence on the career trajectory that follows. Accountancy Capital places practice leavers into in-house roles across the full range of business types and understands both what practice leavers need to get out of the first in-house role and what in-house employers can realistically expect from a practice leaver in their first year.

See the Moving from Practice to In-House Finance guide for the full decision framework, including when to make the move, what roles to target, what to expect in the first year and how to leverage practice experience effectively in the in-house environment.

Senior Roles Within Public Practice

Accountancy Capital also recruits for senior qualified roles within public practice firms at £50,000 and above — specifically where the appointment requires a qualified professional at a career stage typically associated with in-house senior roles. The most common requirements in this category are: senior audit managers or directors being recruited from one practice to another; specialist technical accounting or IFRS advisory professionals being recruited from Big Four for Top 10 or regional firm advisory teams; and outsourced finance professionals — those delivering Virtual FC or outsourced management accounts services — who need in-house finance experience to perform effectively in a practice-based outsourcing role.

These appointments sit within Accountancy Capital’s qualified finance recruitment practice at £50,000 and above, and are briefed and managed through the same search process as in-house appointments. Call 0204 553 8893 to discuss a practice-based senior qualified appointment.

Salary Benchmarks: Practice vs In-House at Qualification

At the two to three years PQE stage, in-house compensation is broadly comparable with practice at Big Four and Top 10 firms. Beyond three years of PQE, the practice career at larger firms typically compensates at a premium to in-house equivalents — but the in-house career offers greater commercial scope, earlier progression to financial leadership and, at PE-backed businesses, equity participation that practice careers do not typically provide. See Moving from Practice to In-House Finance for the full timing and compensation analysis.

What Employers Should Know About Hiring Practice Leavers

In-house employers who hire ACA-qualified practice leavers consistently report that the first three to six months require patience — the practice leaver is adjusting to the pace and format of in-house close cycles, learning an ERP system they have not used before, and building the commercial relationships that the in-house role requires and that practice training does not develop. By month nine to twelve, the practice leaver’s technical depth typically produces a visible quality improvement in the areas they own — statutory accounts preparation, audit management, technical accounting documentation — that the equivalent in-house trained candidate would not provide.

The most common onboarding mistake with practice leavers is expecting them to own the month-end close from week one without any close process guidance. The practice leaver needs specific guidance on the close timetable, the journal posting process and the management accounts format in the first four to eight weeks. Once that guidance has been absorbed — typically by the second or third close — they will improve the close process faster than a candidate who has been doing it the same way for five years.
