We always try to meet our customers out of the work environment which is equally important to us. We are human and believe in trust and long term partnership at every step of your way.


Trust comes from true & sincere human relations.

GB International Consulting is managed by one person here Guillaume Brachet exactly as his father and grand father did before him. 

As you know finding the right information, solution, advisor, lawyer, specialist or accountant is costly and burdensome. You cannot visit and seek the assistance of all professionals in all countries to have access to all available solutions which will allow you to make an informed choice. 


Thanks to his personal experience and the knowledge of the company since 1958 and three generations Guillaume Brachet will guide you and propose you the different alternatives, potential solutions available to you and this in over 78 countries.

The goal is simply to expose to you the various possibilities in the form of an informational study exposing the pros and cons of each possibility in direct relation with his network of lawyers and accountants. We will present you all available options 

The idea is for you to finally be able to make an informed choice for your needs. Our firm is a management consulting company. 


Once our study reviewed and a potential solution is approved by you it is then legally confirmed and duly signed by a registered and regulated local national lawyer or accountant office: you will not only save money and time but you will have an objective and unbiased view on all the solutions that are offered to you so you can go straight to the point in confidence and focus on the most important: your activity.

We believe that a good advising activity can only be lead by one person at a time in order to be comprehensive, trust worthy and coherent.


Guillaume Brachet will be your dedicated and exclusive personal coordinator at all times and every steps of your project. 


Mr Brachet is assisted by the family's and firm's exclusive network of international correspondents: one accountant office and one law firm per country:  

66 professionals in 33 countries. 


These professionals work in constant collaboration with GB International for decades and are all independent offices. 


Each advising team is therefore set for you only.

For the avoidance of any doubt and to be clear our firm is not a lawyer or an accounting firm.


We cannot be regulated, registered and have an office in all countries. The cost would be too high like those found in the "big three" companies. It is virtually impossible for most family entreprises.


We are an international orientation center which will bring you all the knowledge, present all potentials solutions in order for you to make an informed choice and be able to compare the pros and cons for your project. The local lawyers and accounting offices of our network are involved since the beginning. 

They provide right from the beginning the feedback and the updates necessary for you to have the right information. All is then compiled in one informational study so you are informed, master all aspects and have an informed and objective view on all choices. 

You are then put in direct relations with the various lawyers and accountants in the countries chosen with of course our daily assistance. 

So finally all options are clear, make sense to you so we can take you to your summit.
