An audit is a crucial step in the financial management of your business. This accounting engagement verifies the accuracy, compliance, and fair presentation of your financial statements. In a complex economic environment, an audit provides essential assurance for your strategic decisions and ensures compliance with your legal obligations.

Professional accounting firms routinely include this service to ensure the reliability of your financial information. This approach is based on in-depth expertise in accounting and bookkeeping, supported by qualified accounting professionals.

What is an audit?

An audit refers to the set of control and verification procedures applied to a company’s financial statements. The purpose of this engagement is to ensure that the annual financial statements fairly present the entity’s financial position, assets, and results.

The primary objective is to identify errors, omissions, or irregularities that could affect the presentation of the financial statements. The professional reviews supporting documents, checks calculations, and verifies compliance with current accounting principles. This process requires the involvement of a qualified accounting firm.

This approach differs from simple accounting and bookkeeping in that it is analytical and critical in nature. An audit adds significant value to your financial reporting by ensuring its reliability and compliance.

The Different Types of Audits

Audits fall into several distinct categories based on their origin, how they are conducted, and their purpose. Understanding these differences enables companies to better grasp their obligations and optimize their accounting strategy.

There are two main categories of review, distinguished by their origin and the procedures for their implementation. This fundamental distinction determines not only the procedures to be followed, but also which professionals are authorized to intervene and the resulting legal consequences.

Beyond this traditional classification, the audit may also cover specialized aspects depending on the industry and the company’s specific characteristics, sometimes requiring the involvement of qualified industry experts.

Statutory Audit

A statutory audit is required for companies that exceed certain legal thresholds defined by French regulations. The statutory audit is the most well-known form of this mandatory audit, covering approximately 15% of French companies.

The obligations vary depending on the company’s legal form:

• Corporations (SA): a mandatory requirement regardless of their size
• Limited liability companies (SARL) that do not offer securities to the public: appointment is mandatory if they meet more than two of the following three criteria:
• Total assets exceeding 4 million euros
• Revenue exceeding 8 million euros
• Average workforce of more than 50 employees
• SAS and other forms: same thresholds as unlisted SARLs
• Nonprofit organizations and foundations: required if they receive more than 153,000 euros in public grants

The appointment of an auditor must take place within 6 months of the company’s incorporation or of exceeding the thresholds, at the ordinary general meeting. For example, a limited liability company (SARL) in the restaurant industry with 60 employees and 6 million euros in revenue must appoint an auditor.

There are certain exceptions, particularly for subsidiaries that are fully consolidated in the financial statements of a parent company that is itself subject to statutory audit.

Contract Revision

A contractual review may result from a voluntary decision by the company or from a contractual requirement imposed by third parties. Banks, investors, investment funds, or business partners may require this additional assurance before entering into a business relationship or providing financing.

This approach offers the advantage of complete flexibility in the scope and intensity of the audits, tailored to your specific needs and the expectations of your partners. Unlike a statutory audit, you can tailor the engagement to the specific challenges of your industry or to identified risk areas.

Contractual restatement can also be implemented as a preventive measure—before legal thresholds are reached—to anticipate future obligations or strengthen the credibility of your financial statements in a growth environment.

Review Process and Methodology

The audit of the financial statements follows a rigorous methodology structured into several distinct phases.

Planning Phase

The planning phase is the foundation of any successful audit engagement. The professional begins with a thorough analysis of your economic environment, your industry, and the specific characteristics of your company.

This step involves reviewing your internal processes, accounting structure, and information systems. The auditor identifies potential risk areas, whether they are related to the nature of your business, the complexity of your operations, or changes in your business environment.

The assessment of internal controls helps determine the scope and nature of the substantive procedures to be performed. This risk-based approach maximizes the effectiveness of the engagement while ensuring appropriate coverage of the significant issues in your financial statements.

Execution Phase

This operational phase involves rigorous audit techniques and advanced technological tools. The professional accountant applies statistical testing and sampling methods to optimize the effectiveness of audits.

The audits are structured around several methodological approaches:

• Verification of supporting documents through representative sampling
• Verification of Calculations and Carryovers with Computer Assistance
• Validation of provisions and estimates in accordance with accounting standards
• Review of Internal Procedures and Compliance Tests

The average duration of an engagement varies depending on the size of the company: 15 to 25 days for small and medium-sized enterprises (SMEs), 30 to 50 days for medium-sized companies, and up to 100 days for large organizations. Substantive testing generally accounts for 60% of the time, procedural testing for 25%, and finalization for 15%.

Industry statistics indicate that the average rate of detected errors ranges from 3% to 7%, depending on the industry. Bookkeeping and tax audits are a natural part of this comprehensive quality assurance process.

Finalization Phase

The professional summarizes their observations and draws conclusions. They may recommend adjustments or highlight areas for attention to help improve your processes.

Legal Requirements and Thresholds

French regulations impose specific audit requirements based on the size and legal structure of your company.

Companies subject to the statutory audit requirement must comply with strict deadlines. The appointment of the statutory auditor takes place at the general meeting that approves the first financial statements.

Failure to comply with these obligations exposes the company to criminal and civil penalties. Executives may be held liable in the event of a breach, particularly with regard to the management of deductible expenses and the preparation of financial forecasts.

For day-to-day business operations, the amendment provides significant legal certainty.

Benefits of an Audit

An audit of financial statements offers numerous benefits that go beyond mere compliance with legal requirements.

Reliability and Credibility

Your audited financial statements enjoy greater credibility with your financial partners, which has a measurable impact on your access to financing. According to industry studies, companies with audited financial statements have a credit approval rate that is 25 to 30% higher than those with only unaudited financial statements. This assurance of quality also translates into an average reduction of 0.5 to 1 percentage point in the interest rates offered by banks. Banks consider that an audit of financial statements significantly reduces credit risk, justifying more favorable terms. This enhanced credibility improves your banking relationships over the long term and facilitates your future financial negotiations.

Improvement of Internal Processes

The review reveals weaknesses in your accounting and administrative organization, offering a unique opportunity for optimization. This in-depth analysis helps identify flaws in your approval processes, gaps in your internal control system, and inefficiencies in your data entry procedures.

The professional’s recommendations address several critical aspects: standardizing closing procedures, improving the segregation of duties, and strengthening consistency checks. These recommendations are based on industry best practices and specialized accounting expertise.

Beyond the technical aspects, the audit helps professionalize your teams by identifying training needs and providing appropriate management tools. This continuous improvement approach enhances the reliability of your financial information and optimizes the efficiency of your administrative processes.

Legal Certainty

A certified financial statement protects executives from potential liability related to their management. This protection is particularly crucial for independent professionals who are personally liable for their professional activities.

An audit of the financial statements establishes a presumption of good faith in the maintenance of the accounting records and compliance with tax obligations. It serves as a strong defense in the event of a tax audit or a dispute with the tax authorities. This allows executives to demonstrate their diligence in managing the company and their compliance with accounting standards.

This legal certainty also extends to relationships with third parties, creditors, and investors, who can be confident in the reliability of the financial information provided.

Decision Support

Audited financial statements provide a reliable basis for your strategic decisions and financial management.

Choose a qualified professional for the inspection

The selection of the professional responsible for the audit determines the quality of the engagement and the value it adds to your company.

Choosing a qualified certified public accountant or auditor requires a rigorous evaluation of several key criteria. Industry expertise is a key factor: a professional familiar with your line of business will have a better understanding of the specific accounting requirements and risks inherent in your industry.

The firm’s reputation and client references are valuable indicators of the quality of its services. Feel free to ask for testimonials from other executives who have used its auditing services.

A professional’s organizational structure and technical resources directly influence the effectiveness of the audit. A firm equipped with high-performance IT tools and standardized procedures ensures a methodical approach and optimal traceability of the audits performed.

Selection criteria

Choose a professional with industry expertise tailored to your business. Experience in your specific industries ensures a better understanding of the unique challenges and regulatory requirements in your field.

The firm’s reputation and references are valuable indicators. Feel free to consult with other executives who have used its services and to verify its professional certifications.

Also assess the quality of communication and the professional’s responsiveness during your initial interactions. A relationship built on trust is essential to successfully carrying out this delicate assignment.

Economic Aspects

The cost of an accounting firm varies depending on the scope of the assignment and the complexity of your case. This assessment should take into account the various aspects of your company’s economic contribution. Request several detailed quotes to compare the services offered and their terms and conditions.

A review is an investment in the quality of your financial information. This process builds confidence among your stakeholders and ensures sound management. A qualified professional will guide you through this essential process to optimize your accounting procedures and comply with your legal obligations, while keeping associated professional fees under control.

Costs and Pricing Factors

Audit fees vary considerably depending on several structural and organizational factors within the company. For microbusinesses and small SMEs, fees generally range from €1,500 to €5,000 per year, while mid-sized companies can expect costs ranging from €5,000 to €25,000. Large corporate groups and publicly traded companies face budgets that can exceed €50,000 for comprehensive engagements.

Several factors directly influence this pricing:

The cost-benefit analysis between contractual and statutory audits warrants careful consideration. While statutory audits impose a strict and comprehensive framework, their cost may prove disproportionate for certain organizations. A contractual audit, which is more flexible and adaptable, often offers better value for money by focusing on the specific risk areas relevant to your business.

A significant tax benefit lies in the fact that audit fees are fully deductible from the company’s taxable income. These expenses are considered ordinary operating expenses that reduce the tax base, resulting in tax savings of up to 25–28% of the amount incurred, depending on your tax rate. For companies subject to corporate income tax, this tax optimization significantly improves the return on investment from the audit process.
