Transparency & Reliability

Our audits provide an objective picture of your financial situation.

IT Security

Holistic Approach

We don’t think in terms of isolated areas; instead, we take a holistic approach to the following areas:

Forward-Looking Auditing

For us, auditing is not merely a retrospective review of financial statements, but rather an assessment of a company’s future risks and opportunities. To this end, we deploy experienced auditors with in-depth industry expertise. Our audit services meet the highest quality standards. We regularly subject them to internal quality controls as well as external reviews by other auditors, known as peer reviews.

In the area of audit, we offer our clients a wide range of services.

Final review and preparation

  • Statutory and voluntary audits of annual and consolidated financial statements in accordance with HGB, IFRS, and US-GAAP
  • Auditor's review of quarterly and semi-annual financial statements
  • Audit of the early risk detection system
  • IT audits
  • Preparation of annual and consolidated financial statements in accordance with HGB and IFRS

Special exams

  • Audits of Company Formations and Contributions-in-Kind
  • Special Audits Under Stock Corporation Law
  • Transactions Under Conversion Law
  • Other Statutory Special Audits
  • Audits Pursuant to Section 53 of the Budgetary Principles Act (HGrG)
  • Audits Pursuant to the Renewable Energy Sources Act (EEG) and the Combined Heat and Power Act (KWK-G)
  • Audits pursuant to the Real Estate Broker and Developer Ordinance (MaBV)
  • Financial Due Diligence

Accounting

Whether HGB, IFRS, or US-GAAP—we provide expert support for all matters related to national and international accounting.

The legal environment in which German companies operate is subject to constant change.

Fully complying with these requirements—particularly with regard to procedural implementation and documentation—poses significant challenges for accounting departments. This applies, for example, to the methodology and documentation of the annual “impairment testing” required under IFRS, as well as to the handling of certain financial instruments.

On the other hand, regulatory requirements have also increased. In addition, corporate transactions, restructurings, or refinancings present the affected companies with major challenges.

To ensure you are optimally prepared, our experts support you and your accounting department with services in the following areas:

  • Traditional accounting advisory services and preparation of annual and consolidated financial statements
  • Accounting Manual Advice: Assistance with the development or revision of accounting policies
  • Quality Close and Fast Close: Support in structuring and improving financial reporting processes
  • Training of client staff on accounting issues
  • Pre- and Post-Deal Accounting Services: Advice on accounting issues regarding the impact of planned transactions
  • Accounting Advice: Expert opinions on specific accounting topics under IFRS, HGB, and US-GAAP

Valuation

We assist you with all valuation-related matters.

Whether in the context of transactions, restructuring measures, or accounting issues: The valuation of companies or individual asset groups always forms the starting point for a business decision. However, it is often subsequently the focus of critical scrutiny, whether in the context of statutory audits, fairness opinions, or expert arbitration proceedings. We approach this core element of business decision-making with the highest standards of professionalism and quality.

We provide the foundation for your decisions.

Our valuation experts possess comprehensive expertise and the personnel resources necessary to ensure competent and rapid execution of even large-scale valuation projects. Depending on the specific case and industry focus, our valuation specialists work closely with experts from the legal, tax, and management consulting fields, as well as with technical consultants. Of course, upon request, we also support you throughout the entire project beyond the valuation itself.

 

Our Services at a Glance

Appraisal

We determine reliable and transparent enterprise values based on comprehensive knowledge of valuation theory and experience.

Fairness Opinion

Corporate transactions or restructurings require the utmost care and risk awareness. With a Fairness Opinion, we support you in assessing the appropriateness of transaction prices and compliance with legal documentation requirements.

Transaction-Related Valuation

Corporate transactions often require quick decisions. The core question is whether the transaction is worthwhile for you. We support you by analyzing your strategic value drivers and synergies, as well as through sensitivity and marginal price analyses.

Purchase Price Allocation

We advise you on purchase price allocation in the context of business combinations and their accounting treatment, both prior to and after the transaction is completed.

Impairment Test

The impairment testing of goodwill, intangible assets, and financial assets, as well as the early identification of impairment risks, is particularly important.

Asset Valuation

A central focus in the valuation of intangible or tangible assets is both the analysis of specific value drivers for brands, technologies, customer relationships, or assets of all kinds, and the determination of appropriate valuation methods.

Financial Modeling

We support you in developing decision-making frameworks for evaluating investment projects and financing alternatives. Based on our integrated modeling, it is possible to evaluate alternative courses of action within the framework of corporate strategy and assess planning scenarios. This allows for a more nuanced analysis of investment projects and makes the benefits of a transaction transparent.

IT Audits

Key areas of focus in IT auditing include:

  • IT system audit
  • IT due diligence audit
  • Audit of IT-supported business processes
  • Simulation of digital tax audits

Our range of services includes audits of the compliance and security of IT systems as part of external and internal audits. Depending on the type of IT audit, we either analyze the current state of an IT environment against the relevant compliance and security requirements or compare the original objectives with the goals actually achieved.

Our approach to IT audits is specifically designed to identify general issues and potential areas for improvement. In this context, we always provide our clients with actionable recommendations based on the results of our audit work.

The relevant requirements for the compliance and security of IT systems arise from the general provisions of national and international legislation, principles and statements derived therefrom, industry-specific and regulatory requirements, as well as relevant standards for the design of IT processes and IT system landscapes. Listed below are some of these requirements that we take into account in our audit work:

  • German Commercial Code (HGB)
  • German Fiscal Code (AO)
  • Federal Data Protection Act (BDSG)
  • Principles for the Proper Management and Retention of Books, Records, and Documents in Electronic Form, and for Data Access (GoBD)
  • Principles for Proper Computer-Based Accounting Systems (GoBS) of the Federal Ministry of Finance (BMF)
  • Principles for Data Access and the Verifiability of Digital Documents (GDPdU) of the BMF
  • Principles of Proper Accounting When Using Information Technology (IDW RS FAIT 1)
  • Principles of proper accounting when using electronic commerce (IDW RS FAIT 2)
  • Auditing when using information technology (IDW PS 330)
  • Issuance and use of software certificates (IDW PS 880)

Frequently Asked Questions

What does the audit conducted by WIRA AG entail?

WIRA AG’s auditing services include the statutory and voluntary audit of annual and consolidated financial statements in accordance with the German Commercial Code (HGB) and, where required, in accordance with international financial reporting standards. In addition, we review internal control systems, assess risk management processes, and provide support on business management issues. The goal is to create transparency, reliability, and security for shareholders, investors, and other stakeholders.

Which companies are required to undergo an audit?

As a general rule, there is a legal requirement for audits for medium-sized and large corporations, as well as for certain companies due to industry-specific regulations. Whether your company is subject to an audit depends on its legal form, size (revenue, total assets, number of employees), and specific legal requirements. WIRA AG would be happy to provide you with personalized advice on this matter.

What is the process for a final exam at WIRA AG?

Our audit is conducted in a structured and risk-based manner across several phases:
  1. Engagement acceptance and audit planning
  2. Analysis of business processes and internal controls
  3. Performance of audit procedures
  4. Reporting and issuance of the audit opinion
We place great emphasis on efficient, digital, and resource-efficient execution, as well as on transparent communication throughout the entire audit process.

What are the benefits of a voluntary audit?

A voluntary audit builds trust among banks, investors, and business partners. It improves the transparency of financial reporting, strengthens internal processes, and can identify risks at an early stage. It offers a decisive strategic advantage, particularly for growing companies or in the context of business succession and financing rounds.

How long does an audit take, and what documents are required?

The duration depends on the size, complexity, and structure of the company. The audit typically takes several weeks. Among other things, we require financial statements, accounting data, contracts, evidence of provisions, and documentation of internal processes. Before the audit begins, you will receive a structured list of requirements so that the process can be organized efficiently.
