Multi-Currency & Auto Conversion Checkout

Key Features

Geo-IP country detection that auto-switches the storefront into the visitor's local currency on first load

Real-time FX rate retrieval on a scheduled refresh, with a configurable rate source and fallback rate caching

Rounding and price-ending rules engine (force .99 / .00 / .50 endings, round up/down, per-currency overrides)

Theme-embedded currency switcher widget so shoppers can override the auto-detected currency, persisted per session

Shopify Markets-aware integration that respects your configured markets and presentment currencies

Consistent local-currency display carried through to Shopify's native checkout (presentment, not settlement)

Installed as an OAuth app reading catalog and market data via the Admin GraphQL API

Per-store configuration stored in app metafields — no hard-coded settings, fully portable

Webhook subscriptions (app/uninstalled, shop/update) keep the app in sync and clean up on uninstall

About this Product

Multi-Currency & Auto Conversion Checkout is a build-to-order Shopify app that ECOSIRE designs, builds, and installs for your store — it is not an instant App Store download. After purchase, our engineers scope your currency requirements, build the app against your theme and Shopify plan, and deploy it to your store with hands-on QA.

The app detects each visitor's country via geo-IP and automatically switches storefront prices into their local currency, pulling real-time FX rates on a scheduled refresh. A configurable rounding and price-ending engine (for example, force .99 or .00 endings) keeps converted prices looking deliberate rather than machine-generated. A currency switcher widget lets shoppers override the auto-detected choice, and their selection persists across the session.

Architecturally, the app installs as a Shopify app via OAuth, reads catalog and market data through the Admin GraphQL API, stores per-store configuration in app metafields, and listens to webhooks (app/uninstalled, shop/update) so it stays in sync with your store. When your store runs Shopify Markets, we wire the app to respect your existing market and presentment-currency setup so display stays consistent through Shopify's native checkout rather than fighting it.

Because Shopify's checkout always settles in your store's currency, this app focuses on presentment and display — honest, accurate local-currency pricing that reduces the "surprise foreign price" friction that loses cross-border carts. We tailor geo rules, rounding, supported currencies, and switcher placement to your catalog. Every build includes installation, a walkthrough, and a defined support window. If your needs are simpler or more complex than the seed feature set, we adjust scope and quote accordingly.

Who this is for

Cross-border DTC merchant

Sells one catalog into several countries and loses international carts when shoppers see unfamiliar home-currency pricing. Wants automatic local-currency display without manually maintaining price lists.

Shopify Markets operator

Already runs Shopify Markets but wants a polished, consistent currency switcher and clean rounding that Shopify's defaults don't fully cover, wired to respect existing market and presentment settings.

Growth/CRO lead at a scaling brand

Owns conversion rate and treats the 'surprise foreign price' moment as a measurable drop-off. Wants geo-detected local pricing with deliberate price endings to reduce checkout friction across regions.

Frequently Asked Questions about Multi-Currency & Auto Conversion Checkout

Is this an instant Shopify App Store download?

No. This is a build-to-order app. After purchase, ECOSIRE scopes your requirements, builds the app against your theme and Shopify plan, and installs it on your store via OAuth. You get a tailored build rather than a generic listing, so a short delivery lead time applies.

How long does delivery take?

A standard build is typically delivered within about 5 to 10 business days from the kickoff call, depending on the number of currencies, your theme complexity, and whether Shopify Markets is involved. We confirm a firm timeline during scoping before any build work begins, and we keep you updated through install and QA.

What ongoing support and updates do I get?

Every build includes a defined post-launch support and bug-fix window so we can resolve anything found after go-live. Beyond that, we offer optional ongoing maintenance covering FX source changes, Shopify API version upgrades, theme updates, and new currency or market additions. Support terms are agreed in writing before delivery.

Does this change the currency my store actually gets paid in?

No. Shopify's checkout always settles in your store's payout currency. This app handles presentment and display — showing accurate local-currency pricing with smart rounding so international shoppers see familiar prices. It reduces 'surprise foreign price' friction without altering how funds are settled to you.

Does it work with Shopify Markets, and what if I don't use Markets?

Yes. If you run Shopify Markets, we wire the app to respect your configured markets and presentment currencies so display stays consistent through native checkout. If you don't use Markets, the app can drive geo-IP detection and the switcher on its own; we scope the right approach for your plan during the kickoff.
