Why do Magento 2 shops lose customers at checkout?
Magento 2's standard checkout spreads the order process across multiple pages. Every additional click is an opportunity for the customer to abandon the purchase. Studies show: Up to 70% of all shopping carts are abandoned before purchase is completed. — often because of a checkout process that is too long or confusing.
The STM Smart One Page Checkout Extension This solves that problem. Address, shipping method, payment method, and order summary are all displayed together on one page. Your customers immediately see what to expect—without switching pages or losing their bearings. The result: Shorter order times, fewer abandoned purchases, and a measurably higher conversion rate.
What is a One Page Checkout Extension for Magento 2?
A One Page Checkout Extension for Magento 2 This module replaces Magento 2's standard multi-step checkout process with a single, integrated checkout. Instead of entering their address, shipping method, and payment on separate pages, your customers see all steps simultaneously on one page—with a live order summary and clearly organized sections.
The Magento 2 standard checkout is considered two-stage process The process is structured as follows: first shipping and address data, then payment method and order confirmation. Each step is rendered in its own knockout component, which means additional waiting time, component loads, and clicks. Evaluations of the Baymard Institute show that each additional checkout step noticeably increases the abandonment rate — especially on mobile devices, where page changes are perceived as a loss of context.
A modern one-page checkout extension solves this technically. asynchronous data loading, compact wayfinding and a clearly structured layout. The STM Smart One Page Checkout Extension This is exactly where it comes in: It reduces the sources of abandonment without requiring you to change anything in Magento core code, theme templates, or your payment configuration — Composer installation, backend configuration, done.

⚙️
Hyvä vs. Luma: which variant is best for which theme?
Magento 2 is currently shipped on two very different theme architectures: Luma as the original, KnockoutJS-based Magento standard and Good as a modern, AlpineJS and Tailwind-based performance theme. Which version of Smart One Page Checkout is available for your shop depends directly on your theme base — and is automatically detected during Composer installation.
On one Hyvä-Shop The extension delivers a checkout fully rendered in AlpineJS — with the performance advantages that Hyvä is known for: no KnockoutJS Bootstrap, small JavaScript bundle size, and instant interaction. If you're already using Hyvä, you'll benefit from checkout speeds significantly faster than the Magento default — the mobile performance profile is particularly effective here.
On one Luma or Luma-based theme (Porto, Ultimo, Magento Blank) The extension integrates seamlessly into the existing KnockoutJS framework. You don't need to migrate your theme, your customizations are preserved, and the configuration is handled entirely through the Magento backend. This flexibility is precisely why the extension is ready to use immediately, even in established online stores.
| Theme Base | Technology | Suggestions |
|---|---|---|
| Hyvä Theme | AlpineJS, Tailwind | Maximum performance — ideal for modern and mobile-first shops |
| Luma (Standard) | KnockoutJS, RequireJS | Proven solution for classic Magento shops without changing themes |
| Porto / Ultimo | Luma-based | Fully compatible — no theme customization required |
| Custom themes | Variable | Verifiable upon request — we will assist with the adaptation. |

How does a one-page checkout reduce shopping cart abandonment?
Many checkout processes fail not due to technical issues, but due to a lack of clarity. Too many individual steps, too many page changes, too little guidance. The Smart One Page Checkout Extension solves this problem with a visibly ordered structure, which builds trust and speeds up the ordering process:
- Numbered steps — Your customers can see where they are in the checkout process at any time.
- Live order overview — Shopping cart contents, shipping costs and total price are always visible
- Sticky progress indicator — stays in view while scrolling, no loss of orientation
- Clear visual sections — Address, shipping, payment and confirmation immediately distinguishable
📱

The standard Magento checkout was developed for desktop computers—on smartphones, it often appears cluttered and cumbersome. The Smart One Page Checkout Extension is optimized for mobile devices from the ground up.
- Compact overview of all checkout steps without horizontal scrolling
- Sticky order bar at the bottom of the screen — order button always accessible
- Touch-optimized Input fields, dropdowns and selection elements

Change Log
Version 1.6.3 — 2026-07-04
Fixed- Per-order withdrawal button in the customer account was effectively invisible on the order detail page (white text with no background) because its brand color CSS variable was only defined inside the withdrawal form. The color is now set directly on the button and a CSS fallback was added.
- The button appeared at the very bottom of the order page on themes (such as Hyvä) where the order detail is a single block that renders its children by name. It is now placed reliably at the top of the order detail.
- The per-order withdrawal button is now hidden for canceled and closed (fully refunded) orders, where a withdrawal does not apply.
- New optional setting "Account button only within the deadline" (default off). When enabled, the button is hidden once the withdrawal period has elapsed, based on the shipment date plus the configured withdrawal period; orders that have not shipped yet always show the button.
Version 1.6.2 — 2026-07-04
Added- Per-order withdrawal from the customer account. Every order in "My Account → My Orders → View Order" now shows a "Submit a withdrawal for this order" button that opens the online withdrawal form pre-filled for that exact order:
- Order number, e-mail, name, billing address and order date are filled in automatically.
- The order's purchased products are listed as selectable checkboxes so the customer can tick exactly which items they want to withdraw; ticking an item switches the withdrawal to "Selected items only" automatically, and the selection is written into the withdrawal record.
- Access is ownership-checked server-side (the
order_idis only honored when the logged-in customer actually owns the order), so no order data can leak to another customer or a guest. - The guest / manual lookup (
ia24checkout/withdrawal/lookup) now also returns the order's line items, so the same selectable product list appears after a successful order lookup even without being logged in.
Version 1.6.1 — 2026-06-17
Added- Online withdrawal form — automatic pre-fill: entering the order number together with the e-mail address used for the order now pre-fills first name, last name, address and order date via a new AJAX lookup (
ia24checkout/withdrawal/lookup). The lookup only returns data when order number and e-mail both match a real order. The order number and e-mail fields were moved to the top of the form with an explanatory note.
- Server-authoritative order totals. Custom fee total segments (eg a surcharge from STM Surcharge Max or any third-party fee module) are now read generically from the quote address totals and displayed with the correct VAT and grand total — calculated server-side. The checkout no longer contains any fee-module-specific code and works with any module that exposes a total segment.
- Withdrawal links (consumer-rights notice and checkout footer) now open in a new browser tab (
target="_blank" rel="noopener").
- Withdrawal form page no longer shows the duplicate page title (the card keeps its own heading).
- Warranty notice links embedded via the admin "Warranty text" field keep their
target/relattributes (Magento'sEscaper::escapeHtml()strip them; they are re-applied after escaping).
Version 1.6.0 — 2026-06-16
Added- Checkout Consumer Rights feature set (EU consumer rights, effective 2026-06-19). New admin section "Stores → Configuration → STM → STM Smart One Page Checkout → Consumer Rights":
- Statutory warranty notice (configurable heading + HTML text) with selectable placements (checkout above the order button, order confirmation page)
- Online right-of-withdrawal form for both registered customers and guests at
ia24checkout/withdrawal— name, address, order number, order/receipt dates, full vs. partial scope, item description and optional reason; standard POST (form_key protected) so it works without JavaScript - Configurable placement of the withdrawal link (checkout legal notices, order confirmation page, checkout footer)
- Logged-in customers get the form prefilled from their default address; submitted values are repopulated via
DataPersistoron validation errors - Soft order matching: the entered order number + e-mail is linked to the real
sales_orderwhen found, but a submission is never blocked on a mismatch - Withdrawal persistence + admin workflow:
- new table
ia24_withdrawal_request(declarativeetc/db_schema.xml) with ORM model/resource/collection - Admin grid under *Sales → STM Withdrawals* (UI component listing, ACL
IA24_OnePageCheckout::withdrawal) plus a detailed view with status (new/acknowledged/processed/rejected) and internal notes - Automated notifications via
Model\WithdrawalNotifier: merchant alert (recipient configurable, if back to the general store e-mail) and an optional consumer confirmation; two transactional templates (ia24_withdrawal_merchant,ia24_withdrawal_customer) - German translations for all new strings (
i18n/de_DE.csv)
- Carries forward the composer constraint fixes from 1.5.2 and 1.5.3 (PayPal
^100.4 || ^101.0,stm/module-licenseas a hardrequire). No other changes between 1.5.1 and 1.6.0 besides the Consumer Rights feature set above.
Version 1.5.3 — 2026-06-05
Changed- License dependency is now enforced:
stm/module-licensemoved fromsuggesttorequire(^1.0Previously it sat insuggest— and its value was a free-text description ("^1.0 — License validation…"), not a valid version constraint — so Composer never installed or verified the license module. As a proprietary Storetown Media extension this now matches the other STM modules. No code changes.
Version 1.5.2 — 2026-06-05
Fixed- Composer installation failed on Magento 2.4.6+ (including 2.4.8) —
requirepinnedmagento/module-paypal: ^100.4, but Magento raised that core module to the101.0.xseries (2.4.8-p4 ships101.0.8-p4). The^100.4constraint excludes101.x, so dependency resolution aborted withmagento/module-paypal ... could not be found in any versionand everycomposer require ia24/module-onepagecheckoutfailed. Widened the constraint to^100.4 || ^101.0, so the module resolves on both older Magento (module-paypal100.4.x) and current Magento (101.0.x). No code changes — the PayPal integration (Model\MethodCustomization, PayPal Vault handling) is unaffected.
Version 1.5.1 — 2026-04-26
Fixed- Admin "Customize Payment / Shipping Methods" preview rendered without an icon —
Block\Adminhtml\System\Config\MethodCustomizer::getIconUrls()callsgetViewFileUrl('IA24_OnePageCheckout::images/method-icons/.svg')which resolves against the *adminhtml* area, but the 33 method-icon SVGs only existed underview/frontend/web/images/method-icons/, producing 404s on every preview-icon URL. Moved the entiremethod-icons/folder toview/base/web/images/method-icons/so the sameIA24_OnePageCheckout::images/method-icons/...view-file path resolves correctly in both frontend AND adminhtml. No PHP changes; static-content redeploy required after upgrade - Admin config page crash (TypeError) on Magento 2.4.8-p3 with PHP 8.4:
Model\MethodCustomizationnow catches\Throwable(not just\Exception) -TypeErrorextends\Errornot\Exception, so previous catch-Exception blocks let PayPal-VaultafterIsAvailable()TypeErrors bubble up and crash the Admin → Stores → Configuration → OPC page. All 6 defensive catch blocks inModel/MethodCustomization.phpwidened to\Throwable
Version 1.5.0 — 2026-04-15
Added- Ultra-compact layout (4th layout variant): float-based 3-column architecture with address left, shipping+payment right-stacked, sidebar below — hides progress bar, header icons, sidebar logo, trust badges (~250 lines CSS)

etc/config.xml: ultra-compact layout,#0000a0primary /#ff8000accent, Open Sans typography, sidebar-top trust badges, "Developer Support" custom badge with headset icon - Progress bar enabled by default
- Logo dimensions admin config (

header-innermin-heightnow scales with the logo viamax(50px, var(--ia24-logo-max-height, 50px)), keeping the progress bar below the logo regardless of configured size - Payment method cards in One-Column layout no longer break each title word onto its own line — grid
minmax(180px, 1fr)widened tominmax(260px, 1fr)so titles like "No Payment Information Required" and "PayPal Billing Agreement" fit on one or two lines instead of fragmenting per-word - Admin "Customize Payment Methods" section showed "No installed payment methods found" on Magento 2.4.8 with PayPal-Vault installed — root cause was a single
try/catchinModel\MethodCustomization::getAllPaymentMethodsInternal()wrapping bothpaymentHelper->getStoreMethods()(throws TypeError in admin context because PayPal-Vault plugin requires a quote) and the config-based fallback enumeration. Split into two isolatedtry/catchblocks so the admin-safepaymentHelper->getPaymentMethods()config walk runs even whengetStoreMethods()fails

Extremely satisfied! Four layouts, all switchable in the backend. We're currently testing Two Column versus Ultra Compact. Initial findings: Ultra Compact is more popular with our younger target audience. 👍
Jörn Ehlers (Verified buyer)
We're a B2B wholesaler of industrial supplies and installed the extension last week. Our customers often order large quantities of various items. The one-column layout is a perfect fit for our use case—everything is neatly organized, eliminating distractions. The live order overview instantly displays shipping costs and the total price, which is especially important for B2B customers. They often double-check everything before placing their order.
One suggestion for improvement: An option for a comment field directly in the checkout would be helpful for B2B orders. Our customers often enter commission numbers or internal references there.
Sönke Martensen (Verified buyer)
Quick feedback from the field: We installed the extension for a client in the electronics accessories sector. It's running stably on Magento 2.4.6-p7 with PHP 8.3. Mollie integration works flawlessly. The only minor issue we encountered was with address validation, as our address plugin uses its own hook. Storetown Media's support team responded within three hours and sent us a solution. That's how it should be.
Hauke Petersen (Verified buyer)
We run a medium-sized online shop for outdoor clothing on Magento 2.4.7 with the Hyvä theme. The standard checkout was always our problem child—three pages, long loading times, and a consistently high abandonment rate of over 60%. Since installing the STM Smart One Page Checkout Extension, that has completely changed.
The installation via Composer went smoothly in under 10 minutes. There wasn't a single conflict with our existing extensions. What impressed me most was that the extension automatically detects whether Hyvä or Luma is running and adjusts accordingly. We're using the two-column layout, and the live order overview on the right gives customers exactly the transparency they were missing before.
After six weeks of use, we can report the following: The checkout abandonment rate has dropped from 63% to 38%. The average order time has decreased from 4 minutes and 20 seconds to 1 minute and 50 seconds. And what surprised me most—mobile conversions have increased by a whopping 27%. The sticky order bar at the bottom of the screen is invaluable on smartphones.
A clear recommendation for any Magento shop owner who takes their checkout seriously!
Levke Brodersen (Verified buyer)
Finally, a checkout that actually works on mobile! 📱 As the shop manager of an online cosmetics store, I know how important mobile checkout is. Over 70% of our customers order via mobile devices. Anyone interested in this topic... Mobile-First Optimization Anyone who uses a mobile device knows that every unnecessary click is twice as detrimental. The STM Extension solves this elegantly—compact display, no horizontal scrolling, and the order button is always accessible. Excellent!
Gesche Reimers (Verified buyer)
As a Magento developer, I regularly work with various checkout extensions. The STM Smart One Page Checkout Extension stands out significantly in several ways. First, the Composer installation is truly clean. No overrides, no core hacks—unfortunately, this isn't a given with all providers. Second, the compatibility with the Hyvä Theme for Magento 2 It's natively built in. Thirdly: The configuration via Stores → Configuration is intuitive and complete. You really don't need to touch any CSS.
What I particularly like: The numbered steps and the clear visual separation of the areas. This builds trust with the end customer, and trust is the most important factor at checkout.
Frauke Jessen (Verified buyer)
I was initially skeptical about whether the investment would pay off. But after the first few weeks, the numbers speak for themselves. Our conversion rate has measurably increased—and you can see that directly in the revenue. For anyone wondering why customers abandon their purchase at checkout, I recommend the article about... Checkout abandonments and shopping cart abandonmentsThat's when you realize how much revenue you lose due to a poor checkout process. The STM Extension addresses precisely these pain points.
