Common Accounting Errors Found During Due Diligence in Turkish Companies

Common Accounting Errors Found During Due Diligence in Turkish Companies

Whether a company is preparing for an acquisition, attracting investors, restructuring its operations, or entering into a strategic partnership, financial due diligence plays a critical role in evaluating the health of the business. In Türkiye, due diligence extends far beyond reviewing financial statements. Buyers and investors carefully examine accounting records, tax compliance, payroll documentation, corporate governance, and internal financial controls.

Even profitable companies can encounter challenges during due diligence if accounting records are incomplete, inconsistent, or not fully aligned with Turkish regulations. Identifying and correcting these issues before a transaction begins can significantly improve both valuation and investor confidence.

At Azkan Group, we help international companies maintain accurate accounting records and prepare for successful due diligence through comprehensive accounting, payroll, tax, HR, and corporate compliance services.


Why Due Diligence Matters

Due diligence allows investors and buyers to assess the financial and operational condition of a business before completing a transaction.

The review commonly covers:

  • Financial statements
  • Accounting records
  • Tax compliance
  • Payroll administration
  • Employee obligations
  • Corporate governance
  • Internal controls
  • Regulatory compliance

The objective is to identify financial risks before ownership changes.

Well-organized accounting records help transactions proceed more efficiently.


Incomplete Accounting Records

One of the most common issues identified during due diligence is incomplete bookkeeping.

Examples include:

  • Missing supporting documentation
  • Unrecorded transactions
  • Incomplete reconciliations
  • Missing invoices
  • Poor document retention

Incomplete records create uncertainty regarding the accuracy of the company’s financial position.

Maintaining organized accounting documentation is essential throughout the year rather than only before a transaction.


Unreconciled Bank Accounts

Bank reconciliations are a fundamental accounting control.

During due diligence, reviewers often compare:

  • Bank statements
  • Accounting records
  • Cash balances
  • Payment records
  • Outstanding transactions

Unreconciled accounts may indicate accounting weaknesses that require additional investigation.

Monthly reconciliations significantly reduce this risk.


Payroll and Accounting Inconsistencies

Payroll should always align with accounting records.

Reviewers frequently compare:

  • Payroll reports
  • Salary payments
  • Accounting entries
  • Payroll tax records
  • Employer contributions
  • Employee benefit expenses

Differences between payroll and accounting may require extensive explanations during due diligence.

Regular payroll reconciliations help maintain consistency.


Outstanding Tax Issues

Tax compliance is another important review area.

Due diligence teams commonly examine:

  • Tax filings
  • Payment history
  • Tax reconciliations
  • Outstanding tax liabilities
  • Tax correspondence
  • Compliance procedures

Unresolved tax matters may affect both transaction negotiations and business valuation.

Companies should address potential tax issues as early as possible.


Weak Documentation for Expenses

Expense documentation often receives close attention.

Reviewers may verify whether expenses are supported by:

  • Supplier invoices
  • Internal approvals
  • Contracts
  • Payment confirmations
  • Accounting records

Insufficient documentation may raise questions regarding internal controls and financial reporting.

Clear approval procedures strengthen accounting reliability.


Employee Liability Issues

Labour-related obligations also influence financial due diligence.

Reviewers may examine:

  • Employment contracts
  • Payroll records
  • Leave balances
  • Bonus obligations
  • Severance provisions
  • Employee benefit commitments

Accurate HR and payroll records provide greater certainty regarding future employment liabilities.


Inconsistent Financial Reporting

Companies sometimes use different reporting formats for management and statutory purposes.

If reports are inconsistent, investors may struggle to understand:

  • Revenue trends
  • Profitability
  • Payroll costs
  • Operating expenses
  • Cash flow
  • Financial performance

Consistent reporting improves transparency and facilitates decision-making.


Poor Internal Controls

Weak internal controls frequently appear during financial reviews.

Examples include:

  • Lack of approval procedures
  • Limited segregation of duties
  • Missing reconciliations
  • Manual accounting processes
  • Inadequate record retention

Strong internal controls reduce operational risk while improving confidence in financial information.


Missing Corporate Documentation

Accounting due diligence often extends beyond financial records.

Reviewers may request:

  • Articles of Association
  • Shareholder resolutions
  • Board resolutions
  • Corporate registers
  • Authorized signatory records
  • Corporate approvals

Incomplete corporate documentation may delay transactions or require additional legal review.

Proper corporate governance supports stronger due diligence outcomes.


Foreign Currency Accounting Issues

International companies operating in Türkiye often manage transactions in multiple currencies.

Common issues include:

  • Exchange rate inconsistencies
  • Incorrect foreign currency valuations
  • Incomplete exchange rate documentation
  • Currency translation differences
  • Payroll budgeting discrepancies

Accurate foreign currency accounting improves financial transparency for international investors.


Lack of Regular Financial Reviews

Many accounting issues arise simply because companies review their financial records too infrequently.

Regular internal reviews help identify:

  • Posting errors
  • Reconciliation differences
  • Payroll inconsistencies
  • Tax issues
  • Compliance gaps

Companies that conduct periodic financial reviews generally experience smoother due diligence processes.


Best Practices Before Due Diligence

Preparing for due diligence should begin long before a transaction is planned.

Recommended practices include:

  • Reconciling accounting records monthly
  • Maintaining complete supporting documentation
  • Reviewing payroll regularly
  • Verifying tax compliance
  • Updating corporate records
  • Conducting internal compliance reviews
  • Coordinating accounting, HR, payroll, and legal teams
  • Working with experienced local advisors

A proactive approach significantly reduces transaction risk.
