Basic Solutions for Internal Control of Interim Financial Statements

Interim financial statements are a crucial milestone in the accounting cycle—especially for listed companies, foreign-invested enterprises (FDIs), or entities required to undergo semi-annual audits. However, many businesses encounter significant errors—even tax reassessments or post-audit adjustments—due to poorly designed or ineffectively operated internal control systems.

To ensure clarity and accuracy in financial reporting, Viet Uc Auditing recommends that enterprises implement the following fundamental and core solutions during the preparation of their interim financial statements.

1. Clear Segregation of Duties

The first principle in an internal control system is the reasonable separation of duties to avoid conflicts of interest and minimize the risk of fraud. According to International Standard on Auditing (ISA) 315—already localized by Vietnam’s Ministry of Finance—a major weakness in internal control is when one individual performs multiple tasks such as document preparation, bookkeeping, and approval.

A common issue among small and medium-sized enterprises is that a single accountant often assumes too many roles, particularly when staffing is limited. This creates risks of data manipulation, omission of expenses, or incorrect revenue recognition.

Recommended Solutions:

• Separate key functions such as: document preparation, approval, recording, and archiving.
• Use accounting software with clearly defined user permissions.
• Establish an organizational chart that clearly defines the functions and responsibilities of each accounting role.

2. Regular Data Reconciliation and Verification

Financial statements can only be accurate if the underlying data is properly reconciled and verified. Many businesses only discover discrepancies between accounting records and actual figures near the reporting deadline—such as receivable/payable mismatches or inventory discrepancies.

Control Activities to Implement:

• Reconcile receivables/payables with each counterpart.
• Compare cash balances with bank statements.
• Physically count inventory and compare results with inventory management software.
• Check the appropriateness of advances and prepaid expenses.

Recommendations:
 Enterprises should issue standard templates for debt confirmations, conduct inventory checks periodically (monthly, quarterly, semi-annually), and maintain clear reconciliation records to support internal or independent audits.

3. Accounting Entries Should Only Be Made with Valid Source Documents

A key yet often overlooked principle in practice: accounting entries must only be recorded with valid supporting documents. Temporary entries or recording in advance and adjusting later are leading causes of audit adjustments.

According to Circular 200/2014/TT-BTC, a valid accounting document must include: the document name, date, transaction details, amount, and signatures of the preparer, approver, and involved parties.

Key Notes for Interim Reporting Season:

• Do not record expenses without proper invoices or clear economic contracts.
• Only recognize revenue when goods/services have been delivered and accepted by the customer.
• Advances and reimbursements must be settled within the timeframe specified by internal regulations.

Recommendations:
 Implement a document approval workflow in the internal system, and require accountants to verify the legal validity of documents before making entries.

4. Regular Monitoring and Evaluation of the Internal Control System

Internal control is not merely a set of written procedures—it must operate continuously and be regularly monitored and updated. An outdated control system becomes ineffective in a rapidly changing business environment.

Monitoring Activities to Carry Out:

• Periodically review accounting and financial procedures, especially before reporting periods.
• Conduct surprise checks on high-risk transactions: cash disbursements, reimbursements, inventory adjustments, etc.
• Re-train staff on accounting policies, internal regulations, and new financial standards.
• If an internal audit department exists: conduct independent evaluations of control system effectiveness.

For businesses without an internal audit function, consider engaging an independent auditing consultancy to review the internal control system prior to reporting season for timely improvements.

An internal control system not only ensures "accurate reporting" but also helps uphold financial discipline and safeguard company assets. Strict and complete adherence to the four principles above will help businesses:

• Reduce the risk of errors in interim financial statements,
• Easily pass independent audits,
• Increase credibility with investors, banks, and tax authorities.
