One Step Checkout for Magento 2

Key Features

Single-page Ajax checkout that collapses Magento's two-step shipping/payment flow into one reactive viewport with no full-page reloads

Built as a clean module under app/code/Ecosire/OneStepCheckout using layout XML and UI-component overrides — core and vendor/ are never patched

Google Places address autocomplete that populates street, city, region, and postcode from a single typed query

GeoIP-based address pre-fill that detects country/region on page load to cut the number of fields a customer must touch

Delivery date and time selector with configurable cut-off times and blackout dates, persisted to the quote via extension attributes

Order comments and unlimited custom checkout fields (text, select, checkbox, date) saved to the order and visible in the admin grid

Custom field and delivery data exposed through service contracts so it reaches both REST and GraphQL checkout endpoints

Plugin/interceptor and di.xml-based integration that preserves third-party payment methods, tax logic, and theme overrides

Admin configuration panel under Stores > Configuration with field toggles, ACL-gated access, and per-store-view scope

Compatible with both Magento Open Source and Adobe Commerce, including B2B company-account checkout where licensed

Fully responsive layout tuned for mobile checkout where abandonment is highest

Multi-language and multi-currency aware, respecting your store's i18n and locale settings

About this Product

Magento 2's stock checkout splits shipping and payment across two sequential steps rendered by the Magento_Checkout Knockout.js/UI-component stack. Each step transition triggers a fresh round of address validation and quote estimation, and every extra field or click is a place where buyers drop off. One Step Checkout for Magento 2 restructures that flow into a single Ajax page where address, shipping method, payment, and review all live in one viewport and update reactively as the customer types.

This is not a Marketplace one-click install. ECOSIRE builds, installs, and supports this extension on your Magento install — Open Source or Adobe Commerce. We ship it as a proper module under app/code/Ecosire/OneStepCheckout, layering the new layout over core via layout XML and UI component overrides rather than hacking vendor/. The single-page logic is wired through plugins (interceptors) on the checkout data providers and di.xml preferences, so your theme, custom payment methods, and other extensions keep working.

Included as standard: single-page Ajax checkout, Google Places address autocomplete, GeoIP-based address pre-fill to reduce typing, a delivery date & time selector, and order comments plus custom fields persisted to the quote and order via extension attributes. Custom field data is exposed through service contracts so it flows into the REST and GraphQL checkout APIs and onto the admin order view, gated by admin ACL.

Because every Magento store differs — payment gateways, tax rules, B2B company accounts, multi-shipping — we scope each build to your environment before delivery. You get clean, upgrade-safe code, an admin configuration section, and a real engineer on the other end. Honest lead time and ongoing support are spelled out below.

What you get

A custom Magento 2 module (Ecosire_OneStepCheckout) installed in app/code on your store, compatible with your Magento version and edition

ECOSIRE-performed installation: setup:upgrade, di:compile, and static-content deploy run and verified in your staging environment first

Admin configuration section with documented toggles for autocomplete, GeoIP, delivery scheduler, and custom fields

GraphQL/REST exposure of custom checkout fields plus a short integration note for headless/PWA front-ends

Composer-installable package and source so the module is upgrade-safe and version-controlled in your repo

A handover document covering configuration, field management, and rollback steps

Post-delivery support window for bug fixes and a defined update path for Magento patch releases

Who this is for

Conversion-focused store owner

Runs a mid-size Magento 2 store and watches a high share of carts die on the second checkout step. Wants the fewest fields and clicks possible and a measurable drop in abandonment without rebuilding the whole front-end.

Magento merchant with a custom theme

Has an invested-in custom or third-party theme and multiple payment gateways. Needs one-step checkout that integrates via plugins and di.xml without breaking existing payment, tax, or layout customizations.

Operations / fulfillment manager

Needs delivery date/time capture, order comments, and custom fields at checkout so warehouse and dispatch get the right data on the order — surfaced in the admin grid and exported cleanly, not bolted on as a comment string.

Frequently Asked Questions about One Step Checkout for Magento 2

Is this an instant download from the Adobe Commerce Marketplace?

No. This is a build-to-order extension. ECOSIRE builds the module for your specific Magento version, edition, theme, and payment setup, then installs and verifies it on your store. There is no instant Marketplace download — you get code scoped to your environment and a real engineer behind it.

How long until it's live on my store?

Typical delivery is around 7 to 14 business days after we confirm scope and get access to a staging environment. The exact lead time depends on your Magento edition, theme complexity, number of payment methods, and any custom field or delivery-logic requirements. We always install and test on staging before touching production, and we'll give you a firm date once we've reviewed your setup.

Will it break my existing payment methods, theme, or other extensions?

No, by design. We integrate through plugins (interceptors), di.xml preferences, and layout/UI-component overrides rather than editing core or vendor/ files. Your active payment gateways, tax rules, and theme customizations continue to work. We test the full checkout against your real payment methods on staging before go-live.

What about ongoing support and Magento upgrades?

Each build includes a post-delivery support window for bug fixes. Because the module ships as clean, Composer-installable code, it stays upgrade-safe across Magento patch releases. When you move to a new Magento minor or major version, ECOSIRE can update and re-test the module under a support or maintenance arrangement — we don't leave you stranded after delivery.

Does the custom field and delivery data work with headless / PWA Studio or GraphQL?

Yes. Custom checkout fields, order comments, and the delivery date/time are persisted to the quote and order via extension attributes and exposed through service contracts, so the data is available on both the REST and GraphQL checkout APIs. If you run a PWA Studio or headless front-end, we provide an integration note; the single-page Luma/Knockout UI applies to traditional storefronts.
