Problems We Solve

  • Your London Shopify store applies 20% VAT to zero-rated products — HMRC exposure.
  • Your Shopify store is slow on mobile — losing London google.co.uk rankings.
  • EU customers see wrong prices and face unexpected customs charges on delivery.
  • Klarna UK or Clearpay is not set up — losing London BNPL conversion.
  • Your London Shopify theme was built without JSON templates — the team cannot edit it.
