Financial Audit

Financial auditing provides reliable accounting and financial information.


Our goal, to adapt to your requests and make available at your disposal multidisciplinary teams able to deal with complex subjects.

Transformation and change management

Change management makes it possible to associate the employees and managers of companies with organizational changes. Accompanying complex transformations involves an assessment of the impacts of these changes, training courses, presentations of new working methods and the objective of supporting the employees of companies.

Our consultants are specialized in organizational consulting and will accompany the conduct of organizational changes related to the evolution of your company.

Due Diligences

We are accompanying you during your acquisitions to ensure the fixing of the essential points of the negotiation.

Thus you will analyze the financial and accounting situation, but also the strategy of the target company and the set of internal procedures implemented by the seller. In addition, we can perform a prior audit to enable you to meet your obligations of vigilance.

Internal Audit

Risk management has become a necessity for companies, organizations set up internal audit services that must anticipate the collateral effects of risks generated by the company's activity.


We support the management bodies and internal audit departments of companies to build, manage, evaluate, outsource internal control processes.

Statutory Audit

Statutory Audit ensures the quality of financial information and ensures the economic security of companies.

We act as a statutory or a contractual auditor (upon a decision of the company) to carry out audits of the financial statements and of the financial information or to issue limited audit certificates in connection with specific business account data. 

Independent Expertise


The companies conduct financial transactions (acquisition, transfer, ...) private or public. When these offers are likely to generate a conflict of interest or to undermine the equality between the shareholders or for any other reasons related to a problem that may call into question the operation, the intervention of an independent expert is strongly recommended prior to the implementation of the current operation.


The independent expert's mission is to issue an independent opinion on the fairness of the transactions or to express an opinion on the valuation methods of the assets contributed.


The certificates we issue are linked to information related to accounting or data underlying accounting. This information can be quantitative, qualitative or related to the entity’s internal control procedures.

Our auditors are able to intervene according to your needs and according to a standard operating procedure.

Corporate strategy

Business development requires a clear definition of the company's strategy. The confidentiality that accompanies these projects and the development of strategic actions require expert support.


We work with national and international companies providing expertise in strategic plans, post-merger support, organizational procedures, negotiations and dispute resolution, acquisitions, and business transfers.


Réunion virtuelle

To serve businesses in order to ensure the quality of their financial information, assist them in their mutation, advise and contribute to risk management. We adapt to the dynamics and firm size to best serve the objectives of value creation, profitability, growth control.

Our goal is to support our customers, enable them to improve their performance, manage their risks, in a changing environment.

Our approach, supporting companies by respecting the notion of societal responsibility, seeking excellence, allowing teamwork and the symbiosis of objectives.
