First questions

What we will ask first

  1. 01Which audit or assurance is required, and by whom?
  2. 02Which auditing standards and licences apply?
  3. 03Is the auditor independent of other work you receive?
  4. 04What is the deadline?

The approach

How WONE Global usually approaches it

  1. Step 1Confirm the requirement and the licensed auditor needed in each country.
  2. Step 2Check independence before anything is agreed.
  3. Step 3Coordinate audit or assurance work across entities.
  4. Step 4Address findings and control gaps.

What is needed varies by country and by matter. Your WONE Global professional confirms the work, timing and fees before anything starts.

  • Audit licensing & independenceAudit work requires jurisdiction-specific licensing and independence checks
  • Ultimate beneficial ownershipLayered ownership complicates identifying the persons behind a counterparty
  • Sanctions conflictsParties are subject to differing sanctions and licensing regimes
