Auditing the trade and service sector is an independent examination aimed at verifying the accuracy and fairness of financial statements. Given that the service sector accounts for over 42% of GDP (General Statistics Office 2023), the nature of continuous transactions and large invoice volumes poses a risk of material misstatements when recording revenue. Circular 200/2014/TT-BTCAuditing is not only a legal obligation for FDI enterprises and listed companies. Independent Auditing Law 2011, and it is also an effective tool for transparentizing cash flow.
In practice, during audits, violations related to trade discounts and procurement cost allocation often result in heavy tax recovery by the tax authorities. Auditing in the trade and service sector acts as a "filter," reviewing the documentation system from contracts to handover minutes. A thorough understanding of these procedures helps accountants proactively prepare documentation, reduce legal risks, and enhance credibility with investors. Let's explore the details of the characteristics and processes of auditing in the trade and service sector below to optimize corporate financial management.
Key features of auditing in the trade and service sector.
The trade and service sectors have distinct characteristics compared to manufacturing, which directly influence auditors' approaches.
The intangibility and difficulty in quantifying products and services.
Unlike tangible goods, services are intangible and cannot be stored. This makes determining the level of completion required for revenue recognition complex. Auditors must focus on verifying the actual existence of the service through quantity confirmation records or service delivery logs.
The diversity and complexity of revenue
Auditing the trade and service sector often encounters mixed revenue models, for example, sales accompanied by installation and maintenance. Separating revenue and cost of goods sold for each segment according to Vietnamese Accounting Standards (VAS) is a major challenge. Auditors need to accurately classify these cash flows to ensure accurate reporting.
High transaction frequency and accounts receivable management
Commercial businesses typically have a large number of retail customers and distributors. The sales-to-cash collection cycle is intense, requiring a robust internal control system. This is to prevent cash losses and discrepancies in accounts receivable, a constant risk in the industry.
Strategic objectives of auditing in the trade and service sector.
Clearly defining objectives helps auditors focus their resources on the areas with the highest risk.
Verify the accuracy and reasonableness of revenue.
The primary objective of auditing in the trade and service sector is to ensure that recorded revenue is genuine and complete. Auditors will monitor for the recording of fictitious revenue to artificially inflate financial statements or the concealment of revenue for tax evasion purposes.
Assess the accuracy of cost of goods sold and inventory.
Commercial inventory includes goods in transit, goods consigned for sale, and goods in stock. Auditors need to verify that the cost of goods sold (FIFO, weighted average) method is applied consistently according to VAS 02. This ensures that asset values are not misrepresented on the balance sheet.
Checking compliance with tax laws.
Audits in the trade and service sector place particular emphasis on Value Added Tax (VAT) and Corporate Income Tax (CIT). Expenses without invoices or unrelated to production and business activities will be excluded when calculating CIT according to Circular 96/2015/TT-BTC. This helps businesses avoid unnecessary late payment penalties.
| Audit objectives | Key content | Legal basis |
| Existence | Revenue from services actually provided | VAS 14 – Revenue and Other Income |
| Completeness | Don't miss any sales invoices. | Accounting Law 2015 |
| Rights and obligations | Inventory ownership | VAS 02 – Inventory |
| Presentation & Explanation | Classification of trade and service revenue | Circular 200/2014/TT-BTC |
Scope and procedures for in-depth auditing of the trade and service sector.
The audit process is meticulously designed to ensure that no material misstatements are overlooked during the accounting period.
Preparation and risk assessment phase
Auditors begin by understanding the business processes, sales methods, and software systems. In commercial and service industry audits, risks often lie in the discount approval process. Initial risk assessment helps develop an appropriate and effective audit program.
Auditing the sales and cash collection cycle.
This is the most important part of the process. Key procedures include reconciling invoices with shipping documents to ensure accurate recording dates. Auditors also send debt confirmation letters and perform cut-off tests 5-10 days before and after the closing date.
Cost audit and purchasing cycle
Audits in the trade and service sector need to carefully review logistics, advertising, and promotional expenses. Auditors should check the validity of promotional programs registered with the Ministry of Industry and Trade under Decree 81/2018/ND-CP, ensuring that all expenses are supported by valid documentation.
Common risks in auditing the trade and service sector.
Identifying risks helps businesses proactively establish strong internal control systems, preventing asset losses.
Risk of misidentifying revenue.
Many service businesses collect payments in advance and record them directly as revenue instead of using account 3387 (Unearned Revenue). This is a common error that is often corrected in audits of the trade and service sector to accurately reflect the nature of the transaction according to the accounting period.
Risks associated with managing slow-moving inventory.
Commercial goods often become obsolete or expire quickly. If a business does not set aside provisions for inventory devaluation as required by Circular 48/2019/TT-BTC, the asset value will be inflated. Auditors will carefully assess the liquidation of this inventory.
Errors in calculating discounts and commissions.
Commercial contracts often include discount clauses based on annual sales. Inaccurate calculations or lack of valid documentation can distort net revenue. Audits in the trade and service sector focus on reviewing discount calculations to ensure accuracy.
Detailed analysis of typical audit procedures
To ensure quality, audits in the trade and service sector employ modern, detailed analytical and testing techniques.
Analytical Procedures
Auditors compare the gross profit margin between periods or with the industry average. If revenue increases sharply but gross profit decreases significantly, auditors will delve into the details of low-cost sales or unusual fluctuations in the cost of goods sold.
Check original documents and records.
In audits of the trade and service sector, the standard documentation must include the contract, delivery note, and electronic invoice. For invoices exceeding 20 million VND, auditors are required to verify non-cash payment documents to confirm the validity of deductible expenses.
Conduct a physical inventory count.
Witnessing the inventory count at closing is mandatory under VSA 501, even for purely trading businesses. This procedure helps confirm the actual existence of the goods. Simultaneously, the auditor assesses the physical condition of the goods to consider the need for provisions.
The impact of tax policies on auditing in the trade and service sector.
Auditors not only need to check figures but also must have a thorough understanding of tax law to advise businesses on optimal solutions.
Value Added Tax (VAT)
The application of tax rates 5%, 8%, or 10% to individual items needs careful review. Audits of the trade and service sector pay particular attention to VAT exemption and reduction policies under National Assembly resolutions, ensuring that businesses apply them correctly to the appropriate subjects and at the right time.
Deductible expenses when calculating corporate income tax.
Auditors often discover entertainment or client conference expenses lacking valid documentation. Audits in the trade and service sector assist businesses in classifying and adjusting these expenses on the Corporate Income Tax Return Form 03/TNDN, helping to clarify tax obligations.
Practical benefits of conducting audits in the trade and service sector.
Conducting regular audits delivers sustainable added value to businesses that goes far beyond mere compliance.
Strengthening the internal control system.
Through audits of the trade and service sector, experts will identify loopholes in inventory management or debt approval processes. This helps prevent internal fraud and asset losses, allowing managers to focus on core business operations.
Increase the value of the business in the eyes of investors.
An audit report with a "Full Acceptance" opinion is proof of financial transparency. This is a passport that helps businesses access bank loans with preferential interest rates or attract strategic investment funds to participate in development.
Optimizing tax obligations
Auditors review tax errors before authorities conduct on-site inspections. This allows businesses to proactively rectify issues, minimizing late payment penalties and back taxes. This is a direct economic benefit of auditing in the trade and service sector.
Notes for accountants preparing for audits in the trade and service sector.
To ensure a smooth and time-efficient audit, the accounting department needs to prepare the following thoroughly:
- Sorting documents: The invoice must be accompanied by a warehouse receipt/delivery note and a liquidation record.
- Reconcile accounts payable: Proactively send reconciliation statements to customers and suppliers early.
- Explanation of the fluctuations: Prepare analyses of the causes of increases or decreases in revenue or gross profit.
Comparison table of commercial audits and service audits
Although often grouped together, these two areas have subtle differences that need to be considered in auditing the trade and service sector.
| Target | Commercial Audit | Auditing the Services Segment |
| Subject of inspection | Tangible goods, warehousing | Manpower, time, results |
| Record revenue | When transferring ownership | According to the completion schedule (VSA 14) |
| Cost of goods sold | Purchase price + Acquisition costs | Direct labor + General production |
| Significant risks | Loss, damage, and inventory | Record revenue before completion. |
