Every business acquisition or major investment carries risk. The purpose of due diligence is simple: ensure that the risks you are taking are the ones you consciously chose — not the ones hidden in a target company’s financial statements, tax history, or management representations. In the UAE, where businesses commonly have undisclosed FTA liabilities, unaudited financial records, informal related party arrangements, and revenue concentrated in relationships that may not survive a change of ownership, professional due diligence is not a formality. It is financial self-defence. Herald’s due diligence audit services provide buyers, investors, and lenders with an independent, comprehensive assessment of any UAE business before a transaction completes.
The UAE M&A market has expanded rapidly since 2022, driven by Comprehensive Economic Partnership Agreements that increased foreign investor confidence, economic diversification initiatives, and a growing wave of succession transactions as first-generation business owners plan structured exits. This surge in deal activity has brought a corresponding increase in due diligence failures — transactions where buyers discovered material problems after closing that competent due diligence would have identified before. The cost of these failures — in purchase price overpayment, tax liability assumption, litigation, and remediation — consistently dwarfs the cost of the due diligence that would have prevented them.
What is Due Diligence and Why Does It Matter?
Due diligence is the process of independently investigating and verifying the financial, tax, legal, and operational position of a business before committing to a transaction. It starts from the assumption that a seller’s information memorandum presents the business at its most attractive — and assigns independent advisors the task of stress-testing those representations against independently obtained evidence.
A comprehensive due diligence engagement answers questions that no information memorandum asks: Are the revenues genuinely recurring, or concentrated in clients who are already considering alternatives? Does the business have undisclosed VAT or corporate tax liabilities that transfer with the shares? Are the fixed assets actually in the condition shown on the balance sheet? Is there pending litigation that management has not disclosed? Each of these questions, if left unanswered, can turn a promising acquisition into a costly disaster.
When Do You Need Due Diligence in the UAE?
- Acquiring a UAE business — majority or minority stake, full or partial acquisition
- Entering a joint venture or strategic partnership with a UAE entity
- Making a private equity or angel investment in a UAE company
- Completing a management buyout — management teams need independent verification of what they are buying
- Pre-IPO readiness review — ensuring the business can withstand regulatory and investor scrutiny
- Bank credit due diligence — lenders require independent verification for significant facility decisions
- Vendor due diligence — sellers commission DD on themselves to accelerate buyer confidence and reduce transaction timelines

Common Due Diligence Red Flags in UAE Transactions
Experience across hundreds of UAE due diligence engagements gives Herald’s team clear visibility of the risks that appear most frequently. Being alert to these issues before you commit is the difference between a successful acquisition and a costly mistake.
- Revenue concentration — more than 40% of revenue from one or two clients represents substantial risk that should reduce the acquisition price or trigger protective deal structures
- Undisclosed FTA liabilities — VAT penalties, unfiled CT returns, or outstanding FTA assessments that transfer with the shares in a share sale
- Related party transactions — non-arm’s length deals between the business and entities owned by the same shareholders distort profitability and require careful analysis
- Inventory overvaluation — particularly common in UAE trading businesses, where stock records frequently do not match physical counts conducted at the time of due diligence
- Working capital manipulation — artificially high working capital presented immediately before deal close through carefully timed payment and collection decisions
- Key person risk — revenue relationships personal to the founder that may not survive a change of ownership without specific contractual protections

Due Diligence Costs and Timeline: What to Budget
Due diligence fees in Dubai depend on the scope of the engagement, the complexity of the target business, the number of DD workstreams required, and the quality and completeness of the data room provided by the seller. For a focused financial due diligence engagement on a straightforward SME acquisition, Herald’s fees typically start in the range of AED 25,000 to 50,000. Comprehensive engagements covering financial, tax, operational, forensic, and AML dimensions for complex multi-entity transactions may range from AED 75,000 to 200,000 or more.
These costs should be viewed in the context of what they protect. A typical UAE SME acquisition where due diligence is not conducted — or is conducted superficially — will frequently see the buyer discover post-completion issues worth 5 to 15 percent of the acquisition price. On a AED 10 million acquisition, that represents AED 500,000 to 1,500,000 of value lost that competent due diligence would have recovered through price renegotiation, deal structuring, or identification of a deal-breaker that prevented the acquisition entirely. The return on investment from professional due diligence is rarely less than 5x to 10x the cost of the engagement — and is often multiples of that.
From a timeline perspective, Herald recommends beginning due diligence scoping discussions as early as possible in the transaction process — ideally before the Letter of Intent is signed, so that the due diligence scope can be incorporated into the LOI terms. This avoids the common situation where due diligence discovers issues that the LOI did not contemplate, creating renegotiation complexity that delays completion. Herald provides a detailed proposed timeline in every due diligence proposal, based on the scope of work and the expected quality of the data room.

Frequently Asked Questions
How long does a due diligence audit take in Dubai?
A standard financial and tax due diligence engagement for a UAE SME acquisition typically takes 3 to 5 weeks from receipt of the data room. Complex multi-entity transactions or those requiring forensic investigation may take 6 to 10 weeks. Herald provides a detailed timeline estimate as part of every initial proposal.
Who pays for due diligence — the buyer or the seller?
In most UAE transactions, the buyer commissions and pays for due diligence. In competitive sale processes, sellers sometimes commission vendor due diligence to accelerate buyer confidence and reduce the overall transaction timeline. Herald works with both buyers and sellers depending on the transaction structure.
Can Herald deliver combined financial, tax, and operational due diligence?
Yes. Herald delivers fully integrated due diligence covering financial, tax, operational, AML, and forensic dimensions under one engagement with a single senior point of contact.
