We have chosen to set up our own database with own address data and payment systems for each language version. So it is a different and new webshop.
For example, you can not select iDEAL payments in the German version (this does not work in Germany), but it does work in the Dutch version. In the German or English version you activate the credit card option of the bank (or PayPal). You also have the opportunity to use a different product line per language.
With a "separate" store you can conduct more target marketing. Possibly with its own layout aimed at a particular country. For example, you can put a German flag on the page so that the visitor quickly goes to the German version (the customers do not notice that there is another database behind it).
We have clearly made a trade-off here because it is a webshop aimed at sales and not a website for information, so you can respond to the specific requirements of a country without restrictions.
It is possible to copy the products from a webshop to your new webshop. For this we charge €50.-
