avenue in modern city

Rsa’s teams bring together qualified professionals, accustomed to working in an international context, who can be of real assistance to your own teams on specific local factors and regulatory obligations in terms of accounting and tax.

  • Mastering different languages, cultures and regulations

To optimise and safeguard your expansion projects in France, it is important to master the new environment in which you hope to grow your business. The language barrier, your dealings with an unfamiliar administrative system, a new and complex regulatory framework, the choice of business structure, recruitment practices… these are all questions that you have to face.

  • Managing a complex and changing social and fiscal environment

To ensure you comply with legal constraints and choose the best fiscal and social options, Rsa is able to provide you with advice based on a high level of skills, the ability to keep competencies and knowledge up to date, and complete mastery of the local regulatory and fiscal environment.

  • Equipping yourself with a flexible and dynamic structure that leaves you free to concentrate on your core business activity and adapt your structure in line with your changing needs is a key factor in success.

Rsa is a partner with the ability to support you in all these aspects and to be of real assistance, providing an effective interface for your own teams.
