Please see Quan Mai's reply in this thread: http://world.episerver.com/forum/developer-forum/Episerver-Commerce/Thread-Container/2017/6/e-commerce-with-multi-site-/.
Does that answer your question?
Thank you for your reply. Nope the Quan Mai's answer is related "multi-site" from end-user perspective and keep the same epi login for backend.
What I really need is, site specific front end and backend (catelog and products with seperate epi login for each site to manage their products and orders) with multi-site license.
It's not something Episerver Commerce fully supports - you can make it work to some extends, but then the disadvantages overweight the advantages. Episerver Commerce does not support access rights for catalogs (so there is no way to grant user A access rights catalog 1, but not catalog 2, and user B to catalog 2, but not catalog 1), or orders (although you can do some tricks to workaround that). We would suggest to go with separated sites instead.
White-label based ecommerce site in Episerver
I would like to understand the feasibility of integrating multi-site with ecommerce feature(white-label sites) in episerver. I’ve searched google and episerver documentation for many hours and the only information I got is, there is a possibility to do multi-site with ecommerce but there is no guidance how to do that.
Is there a way to achive this in episerver? if yes, Please provide the direction or any documentation to refer.
Any help on this is greatly appreciated.
