Many Manufacturers

Hello all,
it is possible (in free or paid version) to create many manufactures and then,
create a shopping cart only for them?

for example, if a client buy 5 products from Manufacturer1
he cannot add items from another manufacturer

and then, create a back-office (or a mail reminder) for every manufacturer?

thank you,
sorry for my english

It sounds more like a multi vendor system that you're looking for.
It's not yet possible to do that with HikaShop.
It will be possible in the future as we are working on that but we still have work to do before we can release that.
