Wie betreue ich einen DE/AT/CH multi-language Shop?

DACH multi-language has three layers most teams underestimate:

• Storefronts & pricing, three separate Magento store-views (de_DE, de_AT, de_CH) with distinct catalogue prices (CH is typically +15-20% due to import + VAT), distinct currencies (EUR for DE/AT, CHF for CH), and distinct payment rails (Klarna for DE/AT, TWINT for CH)
• Tax, 19% MwSt for DE, 20% USt for AT, 8.1% MWST for CH. Cross-border B2B reverse-charge between DE↔AT (intra-EU); CH is non-EU so customs / DDP rules apply for cross-border to CH
• Compliance, DSGVO covers DE + AT (EU), but CH operates under revFADP (the Swiss equivalent, came into force Sept 2023). Cookie banners must respect both, but the CH text differs slightly

We recommend a shared catalogue, three store-views setup over three separate Magento installs, product / inventory / customer data stays in one DB, but pricing / tax / language / payments are per-store-view. Cuts your maintenance overhead in half.
