In order to be able to enable certain payment methods only for individual stores and to ensure that all Shopware statistic can be viewed separately for each shop and that, for example, the conversion rate of your online shop is not distorted by your local shop, it is necessary to create a separate subshop for each store.
To create a new subshop, open the list of subshops in the backend under Configuration → Basic settings → Shop settings → Shops and click on Add entry.
Select Sub shop as the shop type and enter the desired name of your shop under Name. It is important that you use the same URL as for your main shop in the field Host and enter a very high value, e.g. 100, as the position. In this way you make sure that every customer who visits your shop URL always ends up in the main shop and that you can still access the shop without any problems from your POS system.
In Localizations you can define which combination of language and country is assigned to this subshop. In the snippet administration you then have the option, for example, of designing receipts in the respective language.
