Supporting international companies takes more than a thorough knowledge of French rules. It also requires reliable contacts in the countries where our clients operate, and recognition from the organisations that drive France’s attractiveness. That is why Hexagone Advisory has joined selective networks and partnerships that extend our expertise beyond our borders and guarantee you qualified contacts, wherever you are.


Why an international network?.

An independent, human-sized accounting firm cannot have offices everywhere. It can, however, surround itself with the best. Our network allows us to:

The result: coordinated support, in French and in English, with a single point of contact at Hexagone Advisory and qualified partners in the countries that matter to you.

Member since 2025

In 2025, Hexagone Advisory joined the International Practice Group (IPG), an international non-profit association of independent accounting firms, law firms, tax advisors and M&A specialists working in international environments.

Founded in 1988 and headquartered in Switzerland, IPG today brings together around a hundred member firms in some forty countries across five continents. Its members meet at international conferences several times a year and stay in regular contact between these events.

What our membership brings to our clients:

  • Qualified contacts in many countries: we put you in touch with a member firm, selected by its peers, for your set-up, your subsidiary or your operations abroad.
  • Regular exchanges with peers: we take part in the network’s conferences and working groups, which helps us anticipate regulatory changes affecting international groups.
  • Seamless coordination: we manage the relationship with the local firm on your behalf, in your language and according to your group’s reporting standards.
  • A shared culture: IPG members share the same standards of quality, responsiveness and confidentiality.

Joining IPG means offering our clients the proximity of a Paris-based firm with the reach of a global network.
