Society de Portage vs Auto-entrepreneur

Hi Guys,


There is lots of information on SFN about AE but I've never seen anything abut Society de Portage.


I've closed my UK company as it's not worth the hassle (or so I was advised) but I still have the "odd" client who wants my services.


AE is not an option as I cannot guarantee more than 1 client in any year and I would have to indemnify the client against any tax bills from the French government.


Has anyone had experience with Society de Portage? So they work successfully? Are they a tax efficient option as they claim?


Regards, MJS
