Thank you for your interest in getting Shopify Payments launched in Switzerland!
The Shopify Payment team is hard at work to launch Shopify Payments in new countries. However, due to a number of variables, we can not guarantee that we'll be able to launch Shopify Payments in a specific country, nor provide updates on when Shopify payments will be launched. If we are able to launch Shopify Payments then we'll be sure to let merchants in the new country know by updating their Shopify admin.
In the meantime, you will need to use a third-party payment processor available in Swizterland which you can see here.
