Add a currency switcher to the header. Detect the visitor's location and default to their local currency. Allow manual switching between USD, EUR, GBP, CAD, AUD. Update all product prices live, no page reload.

- Manual switching between supported currencies.
- All product prices update live.
- Uses Shopify Markets — no third-party currency app needed.
What you're trying to do
International shoppers convert dramatically better when they see their local currency. Shopify Markets handles the back-end conversion natively; what's usually missing is a visible front-end switcher. A clean currency switcher in the header signals 'we're built for global' and removes the price-conversion friction.
Things to watch out for
- Shopify Markets setup — Fudge configures the supported currencies for you.
- Checkout currency — Fudge handles this: automatically uses the displayed currency.
- Exchange rates — Fudge handles this: shopify updates them daily.
- Tax/duties — Fudge handles this: markets can also auto-display tax-inclusive pricing.
How Fudge does it
Fudge duplicates your live theme into a draft, wires the integration to your real store data, and verifies it works end-to-end before anything goes live. Everything starts in draft — test on the preview, tweak settings, and publish when you're ready. Your live store stays untouched.
Why multi-currency display matters for international stores
International shoppers convert 50%+ better when prices show in their local currency. Multi-currency display detects the visitor’s location, defaults to their currency, and allows manual switching — without page reloads.
When this is worth doing
Build multi-currency display if you ship internationally. Skip if you’re single-country.
The implementation is straightforward, but the conversion lift is substantial.
What makes a great implementation
- Auto-detect location — geo-IP on first visit.
- Manual switcher in header — lets shoppers override.
- 5+ currencies supported — USD, EUR, GBP, CAD, AUD covers most markets.
- Live price updates, no reload — smooth UX.
- Cart respects currency choice — checkout doesn’t surprise the shopper.
Common mistakes to avoid
The biggest mistake is currency switching that breaks checkout. The cart and checkout must respect the displayed currency.
The second mistake is missing the persistence. Once a shopper switches currency, the choice should persist across pages and sessions.
Pair this with UTM capture in lead forms — both are international-traffic-ready improvements.
