After retirement, I decided to keep working as a consultant in Oil and Gas.
I could work for a Belgium company, but they had to pay expensive social charges in Belgium to employ me.
Being retired, I wanted a net as close as possible to my gross salary, without Belgium social charges deducted.
Adexpat had the solution. For all my contracts outside of the European Union my client pays the local social charges and Adexpat employs me on a daily rate.
This is simple, and in perfect respect of the law.
