How do I split my store for UK + EU post-Brexit?

Three patterns, depending on volume:

• Single-store, geo-priced — one storefront with VAT calculated by destination. Cheapest. Good for small UK-first stores selling occasionally to EU.
• Two storefronts, shared catalogue — store for UK (GBP, UK VAT, Royal Mail) and store for EU (EUR, IOSS, DHL Europe). One Magento backend, one PIM, separate checkouts. Most popular pattern.
• Two websites, two backends — legally separate UK Ltd + EU GmbH/BV. Best for £5M+ stores with EU fulfilment hub (Netherlands / Ireland). Magento website-level split.

We architect, build, and migrate live data — including reroute + 301 from old single-store URLs.
