Control assessments map how authorisations, segregations, and reconciliations actually operate on the floor — not only how they appear in a policy binder. We interview process owners, observe a sample of transactions, and test whether exceptions are investigated.

Focus areas

Purchase-to-pay approvals, inventory movement records, payroll change controls, and month-end journal review. Findings distinguish design gaps from operating failures so remediation can be assigned to the right desk.

Relationship to the statutory audit

When we also perform your statutory audit, control assessment evidence can reduce substantive testing in low-risk areas. When another firm signs the opinion, the assessment still stands as a management letter your board can commission independently.
