Due Diligence in Bulgaria
Financial, Tax and Governance Risk Assessment
Executive Summary
Due diligence in Bulgaria is a structured, independent review of a company’s financial, tax, and governance position prior to acquisition, investment, restructuring, or partnership.
Aidos provides independent, risk-focused due diligence designed to identify financial irregularities, tax exposure, governance weaknesses, contractual risks, and structural inconsistencies. The objective is to provide decision-makers with proportionate, clearly documented risk visibility before capital or strategic commitments are made.
Due Diligence forms part of Aidos Advisory, the firm’s strategic and cross-border service pillar.
Why Due Diligence Matters
Transactions involving Bulgarian companies may appear procedurally straightforward. However, material risks often sit beneath reported figures and formal filings.
These may include:
- Inconsistent accounting treatment
- VAT or payroll exposure
- Hidden distribution of profit
- Undocumented related-party arrangements
- ERP data inconsistencies
- Weak contract management
- Regulatory non-compliance
- Unrecorded contingent liabilities
Due diligence is not intended to obstruct a transaction. Its purpose is to provide structured visibility into exposure and proportional assessment of risk.
Our role is independent. We do not promote or broker transactions. We assess exposure, reporting reliability, and compliance posture — and present findings clearly.
Who This Service Is For
Our due diligence services are typically requested by:
- Foreign investors acquiring Bulgarian companies
- Shareholders preparing an exit
- International groups entering the Bulgarian market
- Joint venture partners
- Investors funding Bulgarian businesses
- Companies preparing internal restructuring
We work with decision-makers who require objective risk assessment before committing capital or strategic direction.
Scope of Review
Each engagement is governed by a written engagement letter defining scope, methodology, limitations, and reporting format.
Depending on the engagement, the review may include financial, tax, and legal elements — either independently or in combination. Scope is aligned with transaction complexity and documentation availability.
Financial Due Diligence
We assess the reliability and quality of financial reporting and operational consistency, including:
- Accounting framework and consistency
- Revenue recognition practices
- Sustainability of reported margins
- Working capital structure
- Cash flow reliability
- Debt exposure and contingent liabilities
- Related-party transactions
- ERP system data integrity
The objective is not to re-audit the company, but to evaluate whether reported financial performance reflects operational reality and whether risks are adequately documented.
Tax Due Diligence
Tax exposure in Bulgaria often arises in operational areas rather than headline tax rates.
Our tax review may include:
- Corporate income tax compliance
- VAT registration and reporting risks
- Payroll and social security exposure
- Withholding tax compliance
- Permanent establishment risks (where cross-border elements exist)
- Review of potential hidden distribution of profit
- Open tax audits, disputes, or pending assessments
Where relevant, findings may align with our broader Tax Advisory practice to assess practical remediation steps.
Legal & Governance Review
In cooperation with qualified legal professionals, we review corporate and governance risks, including:
- Share capital structure and ownership
- Corporate filings and encumbrances
- Regulatory licenses and permits
- Governance documentation
- Key contractual risks
- Contract review and contract management practices
Contractual review includes identifying material obligations, change-of-control clauses, termination risks, undocumented side agreements, and weaknesses in contract management processes that may affect transaction value or post-acquisition stability.
Where appropriate, legal review is coordinated with transaction counsel to preserve independence and clarity of responsibility.
Our Methodology
Aidos provides independent, risk-focused due diligence.
We do not provide valuation services.
We do not structure transactions unless separately agreed.
We do not represent both sides of a transaction.
Our methodology emphasizes:
- Senior-level involvement
- Clearly defined and proportionate scope
- Risk classification (Low / Medium / High)
- Executive-level reporting
- Clear identification of material findings
- Practical interpretation of regulatory exposure
Importantly, we distinguish between:
- Material risks requiring structural consideration, and
- Low-risk adjustments that can be addressed through corrective action, contractual protection, or post-transaction remediation.
This proportional approach helps prevent unnecessary deal disruption while preserving full transparency regarding exposure.
Reports are structured for board-level and investor-level decision-making.
Independent and Proportionate Approach
Larger advisory firms may provide comprehensive transaction advisory services with extensive team structures.
Our approach is deliberately structured and proportionate:
- Direct senior engagement
- Transparent and defined scope
- Independence and conflict awareness
- Clear and concise reporting
- Scope aligned with transaction complexity
Each engagement is tailored to the specific risk profile and strategic context of the transaction.
Governance & Professional Standards
Each engagement includes:
- Written engagement letter
- Clearly defined scope and limitations
- Confidentiality commitments
- Liability limitations defined per case
- Professional indemnity coverage
Our due diligence services align with our broader governance and compliance framework.
Cross-Border Coordination
Where transactions involve international elements, we coordinate with selected partners within the Aliant+ international network to address cross-border tax and legal considerations.
This ensures alignment between Bulgarian findings and international structuring or reporting implications where relevant.
Scope of coordination is defined within each engagement.
Relationship to Other Services
Due diligence frequently intersects with:
- Tax Advisory
- Aidos Accounting & Payroll
- Company Registration and restructuring
However, due diligence is positioned as a distinct advisory engagement within Aidos Advisory, separate from routine operational services.
