Problems We Solve
- Your Shopify store applies 20% VAT to zero-rated products — HMRC compliance risk.
- Your store is slow on mobile, hurting google.co.uk rankings and checkout conversion.
- You sell to EU customers after Brexit without correct duty and VAT configuration.
- Klarna UK or Clearpay is not set up — you are losing BNPL conversion.
- Your Shopify theme was built without JSON templates — the merchant team cannot edit it.
