EXTERNAL AUDIT · 2027

External Audit Process in Dubai 2027

What the auditor actually does at each phase — from acceptance and risk assessment to the signed opinion

Most business owners only see the visible parts of an audit — the document requests and the final report. Behind that sits a defined methodology that auditors follow, from deciding whether to accept the engagement to forming a professional opinion on whether your financial statements are free from material misstatement.

Knowing what happens at each phase makes the engagement far less opaque. It also helps you anticipate where your team will be asked for input, where delays typically occur, and what the auditor needs from you at each stage. If you want a client-side to-do list rather than an explanation of the auditor's work, see our external audit engagement checklist.

At One Desk Solution, our audit and assurance team carries out statutory audits for UAE businesses and walks clients through each phase, so there are no surprises between kickoff and the signed report.

1. The Audit Process at a Glance

2. Phase 1: Client Acceptance & Engagement Letter

Before any work begins, the audit firm decides whether it can accept the engagement. This is a professional-standards step, not a formality.

• The firm confirms it is licensed and, where relevant, approved by your Free Zone authority — see our guide on who can perform a statutory audit in UAE
• It assesses independence — no conflicts of interest with management or owners
• It considers the integrity of management and whether the engagement carries unacceptable risk
• An engagement letter is issued setting out scope, responsibilities, fees, and the reporting deadline

3. Phase 2: Planning & Risk Assessment

• Understanding the business: the auditor learns your industry, revenue streams, systems, and control environment
• Risk assessment: identifying areas where material misstatement is most likely — revenue recognition, inventory, related-party transactions, significant estimates
• Setting materiality: deciding the threshold above which an error would influence a reader's decisions
• Designing the audit approach: choosing which areas get detailed testing and which are sampled or reviewed analytically

4. Phase 3: Testing & Evidence Gathering

Procedure	What the Auditor Does
Controls testing	Checks whether key internal controls (approvals, segregation of duties, reconciliations) operate as described
Substantive testing	Verifies balances and transactions directly against invoices, contracts, bank statements, and other evidence
External confirmations	Obtains direct confirmation from banks, customers, or suppliers of balances owed or held
Analytical procedures	Compares current-year figures to prior years and expectations to flag unusual movements
Inventory and asset verification	Observes or confirms existence and valuation of stock and fixed assets where relevant
Tax and compliance review	Checks that VAT, Corporate Tax, and payroll-related balances are consistent with filings and supporting records

5. Phase 4: Completion Procedures

• The auditor reviews events after the year-end date that may affect the financial statements (subsequent events)
• A going concern assessment is performed — is the business able to continue operating for the foreseeable future
• Proposed adjustments are discussed with management and, if agreed, reflected in the final figures
• Management signs a representation letter confirming the completeness and accuracy of information provided
• Financial statement presentation and disclosures are reviewed for compliance with the applicable reporting framework

6. Phase 5: Reporting & Audit Opinion

The audit concludes with a signed auditor's report containing the opinion, usually accompanied by the audited financial statements. Many firms also issue a management letter highlighting control weaknesses and recommendations — useful input for your internal audit planning, and relevant to board oversight covered in our board audit committee checklist.

7. Types of Audit Opinion

Opinion	Meaning
Unmodified (clean)	Financial statements present a true and fair view in all material respects
Qualified	Statements are fairly presented except for a specific matter that is material but not pervasive
Adverse	Statements are materially misstated and do not present a true and fair view
Disclaimer of opinion	The auditor could not obtain enough evidence to form an opinion

• A qualified, adverse, or disclaimed opinion can raise questions with banks, regulators, and Free Zone authorities
• Where audited financials underpin tax positions such as Qualifying Free Zone Person status, an unresolved audit issue can have wider consequences — see our tax services comparison for Mainland and Free Zone companies

8. Indicative Timeline & Where Delays Happen

Stage	Indicative Duration	Common Delay Cause
Acceptance & engagement letter	A few days	Slow sign-off or scope disagreements
Planning	A few days to a week	Late information about business changes
Fieldwork & testing	One to several weeks	Incomplete records, slow responses to queries
Completion & reporting	A few days to two weeks	Open adjustments or late representation letter

Timelines are indicative only and depend on company size, record quality, and whether it is a first-year audit.

9. Common Mistakes That Slow the Process

• Treating the audit as a year-end event instead of keeping records reconciled throughout the year
• Not telling the auditor about significant business or ownership changes until fieldwork is underway
• Slow or inconsistent responses to information requests, extending fieldwork
• Disputing proposed adjustments late, instead of resolving them as they arise
• Waiting until the license renewal deadline is close before starting the engagement
