Navigating the new reality of international audits: Clarity, coordination and networks

Refinements to auditing standards ISA 315 and the revised ISA 600 place far greater emphasis on understanding business risk across global groups, as well as clearer accountability for group auditors overseeing component work.

For internationally active and globally mobile organisations, this presents both complexity and opportunity. When managed well, an international audit can deliver assurance, insight and efficiency – not merely compliance.

International exposure is no longer the exception; it is now the norm. Group structures increasingly span regions, service centres, shared platforms and geographically dispersed teams.

As Chetan Mistry, Audit Partner at S&W, explains: “We are a global economy, which means that when we look at audit, we’ve seen quite a change in the last few years.”

Those changes are driven not just by scale, but by the nature of risk. Modern group audits now focus less on isolated financial statements’ numbers and more on how business risks emerge and interact across geographies, feeding directly into how group audits are scoped and executed.

The revised ISA 600 has sharpened expectations around how group audits are performed. It clarifies what constitutes a component –  which can be a subsidiary, region, business unit or service centre – and reinforces that the group auditor remains responsible for all component work contributing to the consolidated opinion.

As Britney Barnett, Audit Director at S&W, highlights, this has real practical implications: “The standard makes it clear that the group auditor is responsible for the component audits. That’s why communication and involvement from the very start are so important.”

Effective group audits now rely on risk‑based scoping, careful coordination and clear direction – rather than blanket full‑scope audits across every entity.

Multiple jurisdictions bring multiple pressures: time zones, languages, local reporting requirements and cultural differences.

According to Mistry, how these moving parts are managed often determines success or failure: “The communication channels are absolutely vital. They can be the difference between a strong project delivered on time and one that risks missing its objectives.”

Early planning allows teams to risk assess sooner, front‑load work where possible, and set clear escalation routes if issues arise. Importantly, it also gives finance teams clarity around expectations – enabling them to manage audit demands alongside business‑as‑usual responsibilities.

In many international audits, complexity sits at the local level. Processes may differ, documentation may be produced in another language, or local finance teams may operate semi‑independently from the group.

As Barnett notes: “You might be doing a group audit, but the way things are done locally might be challenging – and this is where using other auditors can really help.”

Engaging local component auditors can bring speed, understanding and practical insight. However, the key is close oversight by the group auditor, ensuring component teams neither over‑audit nor under‑audit, and that all work aligns with group risk assessments.

Modern audit platforms now allow global teams to share documentation, track progress and maintain real‑time visibility across jurisdictions.

According to Mistry, this creates a clear benefit for both auditors and finance teams: “Having a global view in one place is incredibly helpful when you’re coordinating work centrally and working with multiple teams.”

But while technology enhances efficiency, it does not replace professional judgement. Group auditors still need a deep understanding of the business, its risk profiles and how individual components fit into the wider group.

International audits don’t always require a uniform approach and not every component benefits from being audited by a large global firm.

S&W’s strength lies in combining mid‑market specialism with international capability through CLA Global, enabling us to support global audits in a flexible and pragmatic way.

As Mistry explains: “We’re not competitors to the group auditor; we’re complementary. We provide a bespoke, high‑quality service that supports the overall audit.”

S&W frequently acts as a second provider on global audits led by Big Four or other large firms. This model works particularly well where components are lower risk, operationally complex or better suited to a more relationship‑driven audit approach.

With many of our people coming from large‑firm backgrounds, group auditors can rely on the quality of our work, without unnecessary duplication or disruption to group timetables.

One of the most effective tools in international audits is also one of the simplest: the post‑audit debrief.

As Mistry notes: “When you give teams the opportunity to debrief and then act on that feedback, engagement improves year on year – as does audit quality.”

By involving group finance, local teams and component auditors in that feedback loop, organisations can continually refine processes and reduce friction in future audits.

International audits are becoming more complex, but with the right approach they can also become more insightful and efficient. Early planning, strong communication and access to both global and local expertise are now essential.

For growing businesses with international ambitions, working with an audit firm that combines technical rigour, network reach through CLA Global, and a collaborative mid‑market mindset, can make all the difference.
