Do I need to start a business?

Hi,

my mother lives in the Czech Republic and produces hand made ceramics. She would like to sell the goods through an internet shop in Denmark as well. I live in Denmark. She would run the webshop and do all the accounting in the Czech Republic. To send the goods from the Czech Republic would be too expensive. Therefore, we would like to do it such, that we would bring it in our car and when somebody would like to buy it through the webshop, my mother would tell it to me and I would pack it and send it from Denmark. Do I need to run a business in Denmark to do that? The point is that all the accounting would be done in the Czech Republic and I would be just packing it and sending by a post.

Thanks for your answers in advance.
