Services in close link to your business

Does your legal structure lead you to have your accounts certified by an auditor ? Do you want to have an objective and fair opinion on the value of a business in the context of a business purchase or sale? Do you want to change your accounting system or set up efficient internal control ?

Our teams are able to support you in the following missions

Statutory audit

The legal audit of accounts verifies the economic situation of a company and the accuracy of its financial statements. The result of the independence of the auditor, the report on the company’s annual accounts is sent to shareholders and published at the registry. In addition to its mandatory nature, the legal audit allows you to anticipate risks and reassure your partners.

Contribution, merger and transformation auditor

The contribution and merger auditor, an independent expert with transversal understanding, is responsible for evaluating contributions in kind, certifying the absence of overvaluation of contributions or units and verifying the fairness of remuneration. His appointment is mandatory when contributions in kind are transferred as part of an increase in capital or setting up a business.

IT and cybersecurity audit

Led by a team of specialized consultants and IT lawyers with recognized skills, the IT & Cybersecurity audit allows you to map the interactions between your software and your infrastructure, but also to test the stability of your information system and its level of vulnerability to intrusions. This audit, intended to help you take corrective measures, also allows you to better prepare your GDPR compliance.

CSR audit

Every company must now integrate social responsibility, also known as CSR, into its development strategy. Our experts are responsible for evaluating the societal, social and environmental performance of your company and its level of compliance with the guidelines defined in the ISO 26000 standard. We also support you in your steps in connection with the obligation to declare Extra-Financial Performance (DPEF).

Financial, social and legal audit

The social audit allows you to assess the compliance of internal practices in your company, including compliance with labor law and collective agreements. In particular, we analyze your human resources policy in order to verify its effectiveness and measure the risks. This audit may also be required as part of the establishment of a social and economic committee (CSE).

As part of the legal and tax audit, we assess the potential risks associated with your business. To carry out this mission, we conduct a review of your tax packages and tax integration agreements, your transfer pricing policy or your reliable audit trail (PAF).
