Precision over Generalization: The Ultimate Guide to Agreed-Upon Procedures (AUP) Engagements
In the financial world, the word “audit” often dominates the conversation. Businesses assume that if they need to verify a financial figure, they must commission a full statutory audit. However, a full audit is a broad, heavy instrument designed to provide reasonable assurance on the entire set of financial statements. It is time-consuming, expensive, and often overkill when you only need to answer a specific question.

What if you don’t need to know if the entire balance sheet is correct? What if you only need to verify that your top 10 customers actually owe you money? Or that your payroll calculations comply with UAE labor law? Or that a specific grant was spent according to the rules?
This is where the Agreed-Upon Procedures (AUP) engagement comes in. It is the scalpel of the accounting world—precise, targeted, and highly effective. Governed by the International Standard on Related Services (ISRS 4400), an AUP allows you to define exactly what the auditor checks and exactly how they check it. In the complex, rapidly evolving business landscape of the UAE, where agility and specific compliance (like VAT refunds or Corporate Tax deductions) are paramount, the AUP is becoming a vital tool for smart decision-making.
This comprehensive guide will demystify the AUP engagement. We will explore how it differs from an audit, when to use it, how to structure it, and why it might be the most valuable financial service you haven’t been using.
Key Takeaways
- No “Opinion” is Given: Unlike an audit, an AUP does not result in an opinion (positive or negative). It results in a report of “Factual Findings.” The reader draws their own conclusions.
- You Define the Scope: The “Agreed-Upon” part is literal. You, the client, dictate exactly what procedures the auditor will perform. This offers unmatched flexibility.
- Speed and Cost-Effectiveness: Because the scope is narrow and targeted, an AUP is typically faster and cheaper than a full audit or review.
- Ideal for Specific Risks: It is the perfect tool for investigating suspected fraud, verifying grant usage, checking compliance with bank covenants, or validating a specific acquisition target.
- Third-Party Reliance: Banks, regulators, and investors often prefer AUPs for specific verifications because they provide granular detail that a general audit opinion hides.
What is an Agreed-Upon Procedures (AUP) Engagement?
An AUP is a non-assurance engagement in which an auditor performs specific test procedures on financial or non-financial subject matters and reports the factual findings. It is governed by ISRS 4400 (Revised).
The Core Philosophy: “Factual Findings”
The most important distinction of an AUP is that the auditor acts as a fact-finder, not a judge.
- In an Audit: The auditor says, “In our opinion, the inventory balance is fairly stated.” (Subjective assurance).
- In an AUP: The auditor says, “We counted 500 units of Inventory Item A. The client’s records showed 550 units. There is a difference of 50 units.” (Objective fact).
The auditor does not say “this is good” or “this is bad.” They simply report exactly what they found based on the procedures you asked them to run. It is up to the user of the report (you, the bank, the investor) to decide if a 50-unit discrepancy is acceptable or a disaster.
AUP vs. Audit vs. Review: Choosing the Right Tool
Business owners often confuse these three services. Using the wrong one can lead to wasted money or insufficient assurance.
| Feature | Statutory Audit | Review Engagement | Agreed-Upon Procedures (AUP) |
|---|---|---|---|
| Objective | To express an opinion on the entire financial statements. | To state if anything came to attention suggesting errors (limited assurance). | To perform specific tests and report factual findings. |
| Assurance Level | Reasonable Assurance (High). | Limited Assurance (Moderate). | No Assurance (Factual Findings only). |
| Scope | Broad (Whole Company). Determined by Auditor. | Broad (Whole Company). Mostly Analytical. | Narrow & Specific. Determined by Client. |
| Cost & Time | High. | Medium. | Low to Medium (Depends on scope). |
| Report User | General Public / Shareholders. | Shareholders / Banks. | Restricted to parties who agreed to the procedures. |
If you need a stamp for your trade license renewal, you need an External Audit. If you need to check if your procurement manager is getting kickbacks, you need an AUP.
When Should You Use an AUP? (The Strategic Use Cases)
In the UAE’s commercial environment, AUPs are becoming increasingly popular due to their flexibility. Here are the most powerful use cases.
1. M&A Due Diligence (The “Deep Dive”)
You are buying a small competitor. You don’t trust their inventory valuation or their customer list. You don’t need to audit their whole company.
The AUP: “Select the top 20 customers by revenue and call them to verify the outstanding balance and contract terms.”
The Value: You get specific verification on the high-risk assets without paying for a full audit. (Link to Due Diligence Services).
2. Fraud Investigation
You suspect an employee is creating fake vendors.
The AUP: “Extract a list of all vendors created in 2024. Verify each vendor against the UAE Economic Department’s trade license database. Match bank account names to vendor names.”
The Value: A forensic, fact-based report that can be used for internal disciplinary action or legal proceedings. (Link to Internal Audit).
3. Bank Covenant Compliance
Your bank loan requires you to maintain a specific Debt-Service Coverage Ratio (DSCR) or limiting capital expenditure.
The AUP: “Calculate the DSCR based on the certified management accounts using the formula defined in the Loan Agreement. Verify that Capital Expenditure did not exceed AED 500,000.”
The Value: The bank gets an independent verification of the specific metric they care about, satisfying their risk department.
4. VAT Refund Verification
You are applying for a massive VAT refund from the FTA. You want to be 100% sure your documentation is perfect before filing to avoid an audit trigger.
The AUP: “Select a sample of 50 purchase invoices > AED 10,000. Verify that each invoice contains a valid TRN, date, and tax amount as per UAE VAT Law.”
The Value: Peace of mind and risk mitigation before engaging with the tax authority. (Link to VAT Consultants).
5. Corporate Tax “Substance” Check
You are a Free Zone entity claiming the 0% tax rate. You need to prove you have “adequate substance” (employees and assets) in the Free Zone.
The AUP: “Verify that all employees listed on the payroll hold visas sponsored by the Free Zone entity. Verify that office rent payments were made to a landlord within the Free Zone.”
The Value: Documentation to defend your tax position. (Link to Corporate Tax).
6. Related Party Transactions
Shareholders want to ensure that transactions between sister companies are fair (at arm’s length).
The AUP: “Compare the prices charged to Related Party X for services against the standard rate card charged to external customers.”
The Anatomy of an AUP Engagement: The 3-Step Process
Unlike an audit, which follows a standard path, an AUP is highly collaborative.
Step 1: Defining the Terms (The Engagement Letter)
This is the most critical step. You, the auditor, and any third party (like a bank) sit down to define: * The Purpose: Why are we doing this? * The Procedures: A detailed, line-by-line list of exactly what the auditor will do. (e.g., “Obtain list,” “Compare X to Y,” “Recalculate Z”). * The Restrictions: Who is allowed to see the report? (AUP reports are usually restricted use).
Step 2: Execution (The Fieldwork)
The auditor performs the procedures exactly as written. They do not deviate. If they find an error, they record it. They do not fix it; they report it.
Example: “We selected 10 invoices. We agreed 9 to the price list. 1 invoice showed a price of AED 100 vs list price of AED 110.”
Step 3: The Report of Factual Findings
The final output. It lists every procedure performed and the corresponding finding. It does not contain words like “assurance,” “opinion,” or “true and fair.” It is a dry, factual recitation of results.
How to Write Effective Procedures (The Art of AUP)
The success of an AUP depends on how well you write the procedures. Vague procedures lead to vague results.
| Bad Procedure (Vague) | Good Procedure (Specific) |
|---|---|
| “Check if expenses are reasonable.” | “Select all expenses over AED 5,000. Compare the amount to the supporting supplier invoice and verify approval signature by the Dept Head.” |
| “See if the bank balance is correct.” | “Obtain the bank confirmation letter and agree the balance to the General Ledger code 1010 as of Dec 31st.” |
| “Review payroll.” | “For a sample of 10 employees, recalculate the End of Service Benefit based on the start date in the employment contract and the final salary.” |
The procedure must be so clear that any two auditors performing it would get the exact same result.

Frequently Asked Questions (FAQs) on AUP Engagements
No. If the law (e.g., UAE Commercial Companies Law) or your Free Zone authority requires an “audit of financial statements,” you must have a full audit with an opinion. An AUP cannot substitute for this statutory requirement.
Generally, no. The report is “restricted use.” It is meant only for the parties who agreed to the procedures (e.g., you and your bank). This is because a third party (like a new investor) might misunderstand the findings because they weren’t involved in defining the scope.
Usually, yes. Because the scope is limited to specific items (e.g., just Inventory or just Revenue) and there is no requirement to understand the whole internal control environment, it requires fewer hours. However, a very complex, large-scale AUP (e.g., forensic investigation of 5 years of data) can cost more than a standard audit.
Yes. ISRS 4400 is a professional standard issued by the IAASB. Only qualified professional accountants can perform an engagement under this standard and issue a valid report.
They report it. Period. In an audit, you might discuss “adjusting” the error to make the financial statements correct. In an AUP, the finding is the finding. “We found a difference of AED 5,000.” The report lists the facts. It is up to you to decide what to do with that information.
Yes! This is a huge advantage. You can have an AUP to verify: * The number of active users on a software platform. * Compliance with environmental standards. * Square footage of a leased property. * Adherence to a specific ISO procedure.
Banks often have “covenants” (rules) you must follow, like “Inventory must not exceed AED 1M.” Instead of paying for a full audit every quarter to prove this, the bank might accept a quarterly AUP report verifying *only* the inventory balance. This saves you money and keeps the bank happy.
Absolutely. This is a common form of accounting review. You can hire EAS to perform an AUP on your monthly bank reconciliations or payroll processing to ensure your internal team is doing their job correctly.
No. Negative assurance (“Nothing came to our attention…”) is for Review Engagements (ISRE 2400). An AUP provides *no* assurance. It provides “Factual Findings.” The distinction is legal and important.
Because there is no “opinion” to formulate and the scope is narrow, an AUP can often be completed in days or weeks, whereas a full audit might take months. Speed is a key benefit.
Conclusion: The Power of Focused Verification
In a business environment drowning in data, the Agreed-Upon Procedures engagement offers clarity. It cuts through the noise of general financial statements to provide hard, verified facts about the specific issues that keep you up at night.
Whether you are closing a deal, satisfying a regulator, or investigating a suspicion, the AUP is your tool for precision. By understanding how to leverage this flexible engagement, UAE leaders can gain the specific insights they need to manage risk and drive value, without the weight and cost of a full-blown audit.
