Über dieses Produkt
Shopify is deprecating checkout.liquid and forcing every Plus and non-Plus merchant onto the new extensibility checkout (Checkout, Thank You, and Order Status pages). If your store still relies on legacy Liquid edits, scripts, or additionalScripts, those customizations stop working — and the standard App Store apps rarely cover the exact fields, blocks, and messaging your store needs.
The Checkout Extensibility Customizer is a build-to-order Shopify app that ECOSIRE designs, builds, installs and supports specifically for your store. It is not an instant App Store download. We scope your requirements, build the Checkout UI Extensions (React + Shopify's @shopify/ui-extensions and Checkout UI components), deploy them through the Shopify CLI as an app, and wire them into the right extension targets — purchase.checkout.block.render, purchase.checkout.delivery-address.render-before, purchase.thank-you.block.render, and Order Status placements.
What you get: trust badges and payment icons, custom fields (gift messages, VAT/Tax ID, delivery notes, PO numbers) persisted to order metafields via the Admin GraphQL API, free-gift and shipping-protection blocks, conditional banners driven by cart attributes, country, or line-item rules, and brand styling applied through checkout branding settings and Checkout Editor app blocks — all without checkout.liquid.
We register the app via OAuth with least-privilege scopes (write_checkouts, read_orders, write_orders as needed), set up any webhooks for order processing, and hand you a checkout that survives Shopify's platform changes. Validation logic uses buyer-journey interceptors so bad input is blocked before payment. Honest delivery: typical builds ship in a defined lead time after a short discovery call, fully QA'd on your theme and live checkout.

- A short handover document covering extension config, metafield keys, and how to adjust content/rules
- A discovery call and scoped build plan confirming targets, fields, and conditional logic before development
- Post-launch verification on your live checkout plus a defined support window for fixes
Für wen das ist
Plus merchant migrating off checkout.liquid
A Shopify Plus store with heavy legacy checkout.liquid edits, scripts, and additionalScripts that break under mandatory checkout extensibility. Needs the same trust badges, custom fields and upsells rebuilt as compliant Checkout UI Extensions before Shopify's deprecation cutoff.
DTC brand owner who wants checkout to match the brand
A direct-to-consumer founder frustrated that the new checkout looks generic and that off-the-shelf apps can't capture the exact gift, VAT, or delivery-note fields they need. Wants a branded, conversion-focused checkout without hiring an in-house Shopify dev.
Operations lead needing structured order data
An ops or fulfillment manager who needs PO numbers, tax IDs, and delivery instructions captured cleanly at checkout and persisted to order metafields, so warehouse exports and accounting integrations get reliable, structured data instead of free-text notes.

Häufig gestellte Fragen zu Checkout Extensibility Customizer
How long until my checkout customizations are live?
This is a build-to-order app, not an instant App Store install. After a short discovery call to confirm your extension targets, fields and conditional rules, ECOSIRE builds the Checkout UI Extensions, installs the app on your store via OAuth, and QA's everything on your live checkout. Typical builds ship within a defined lead time we confirm during scoping; more complex conditional logic or many custom fields can extend it. We give you a clear delivery date before work starts.
What happens after launch — do I get ongoing support and updates?
Yes. Every build includes post-launch verification on your live checkout and a defined support window for fixes. Because Shopify evolves the checkout extensibility platform and @shopify/ui-extensions APIs over time, we can keep the app updated under an ongoing support arrangement. You also receive a handover document so your own team can adjust content and rules where appropriate.
Will this work without checkout.liquid?
That's the entire point. Shopify is deprecating checkout.liquid and additionalScripts. We rebuild your trust badges, custom fields, banners and upsells as native Checkout UI Extensions deployed through the Shopify CLI, placed at supported extension targets. This is the supported, future-proof path that survives Shopify's mandatory migration to extensibility.
Can it capture custom fields like VAT numbers or gift messages and store them with the order?
Yes. Custom fields (gift messages, VAT/Tax ID, delivery notes, PO numbers, and similar) are rendered in checkout and persisted to order metafields via the Admin GraphQL API. The captured data appears in the Shopify admin on the order and is available in order exports and downstream integrations, so your fulfillment and accounting systems get structured data, not free-text notes.
Do I need Shopify Plus for this?
Not necessarily. Many Checkout UI Extension capabilities — app blocks, custom fields, banners and branding — are available to non-Plus merchants on the new checkout, while some advanced targets and deeper customization are Plus-only. During discovery we confirm exactly what your plan supports and scope the build to what Shopify allows on your store, so nothing we promise depends on a capability you can't access.
How does the app get installed and what permissions does it need?
We install it as a private/custom app on your store through Shopify's OAuth flow, requesting only least-privilege scopes the customizations actually require (for example write_checkouts, read_orders, and write_orders where order data is captured). We can also register webhooks such as orders/create or orders/paid if your custom field data needs downstream processing. You review and approve the scopes at install.
