Audit & Assurance at WONE Global

What we do.
How we do it differently.

Audit & Assurance through WONE Global is different in one fundamental way: every engagement is coordinated across jurisdictions by one team, to one standard, with one contact — regardless of how many countries are involved.

"The question is not whether your advisers are excellent in their own market. The question is whether they can deliver the same quality across every market where you need them."

WONE's audit & assurance practice operates through the WONE OS deal flow engine — meaning client briefs are matched to the best-qualified senior partner in each jurisdiction, assembled as a coordinated team, and delivered under one unified quality standard.

There are no referral arrangements between unconnected firms. No hope that someone in another country will pick up the phone. Every audit & assurance engagement at WONE is delivered by a team assembled specifically for that brief — senior partners, the right jurisdictions, the right expertise — coordinated from day one.

Our Services

What we cover
in audit & assurance.

Eight service areas — all delivered with senior partner expertise, all coordinated across jurisdictions, all under the WONE quality standard.

01
Statutory Audit
Independent statutory audit of financial statements across multiple jurisdictions — to local regulatory requirements and WONE's global quality standard, coordinated by one delivery team.
02
Regulatory Audit
Audit and assurance work required by financial regulators, sectoral authorities, and government bodies — including banking, insurance, funds, and public sector entities operating across borders.
03
ESG Assurance
Assurance on environmental, social, and governance reporting — including CSRD compliance for European entities, TCFD-aligned climate disclosures, and integrated reporting across group structures.
04
Internal Audit
Co-sourced and outsourced internal audit services — providing independent risk assessment and control assurance for groups operating across multiple jurisdictions and regulatory environments.
05
Financial Reporting Review
Technical review of financial statements under IFRS, US GAAP, and local GAAP — including first-time adoption, restatements, and accounting policy reviews across cross-border transactions.
06
Risk Assurance
Assurance on internal control frameworks, risk management processes, and compliance systems — for groups where risk oversight crosses jurisdictional boundaries.
07
Transaction Assurance
Financial due diligence, vendor due diligence, and working capital analysis for cross-border M&A — coordinated across every jurisdiction involved in the transaction.
08
Forensic & Investigations
Independent forensic accounting, fraud investigation, and asset tracing across jurisdictions — where the integrity of the investigation depends on the independence of the investigator.
02
Who We Serve

The clients who
come to WONE for audit & assurance.

Four client groups with distinct audit & assurance needs — each served by a team assembled specifically for their situation, jurisdiction, and brief.

Boards & Audit Committees
Boards requiring independent audit oversight across group structures — where the audit function must match the geographic complexity of the business, not just the head office jurisdiction.
Regulators & Public Bodies
Regulatory authorities, government bodies, and multilateral organisations requiring independent assurance on entities operating across multiple jurisdictions.
Investors & Lenders
Equity investors and lenders requiring financial assurance on target companies, portfolio businesses, or borrowers operating across multiple jurisdictions and accounting regimes.
CFOs of International Groups
Finance teams managing multi-jurisdictional audit requirements — where WONE provides a single coordinated audit function that replaces the complexity of managing multiple local audit firms.
03
Sectors

Deep sector expertise
across every major industry.

WONE audit & assurance partners bring sector expertise alongside jurisdictional knowledge — meaning clients receive advice that understands the industry as well as the law, the tax regime, or the accounting standard.
