Features
Inside One Page Checkout
Seven things the free extension adds to the checkout you already run. Pick any one to see it.
Install anything else and it keeps working
One Page Checkout never replaces a class, a route, or a template, so the payment, shipping, and tax extensions you run keep working.
- Chains with validators other extensions register
- Gateways keep their certified components
- Stands down on Hyvä Checkout automatically
Express pay above the form
Every wallet button is rendered by its own gateway, so approval flows and Pay Later offers behave exactly as the provider built them.
- Gateway-owned buttons
- Approval flows stay certified
- Row sits above the first field
Sections save themselves
A section saves in the background the moment it is complete and valid. Payment shows a progress line until shipping is stored.
- Saves when complete and valid
- Payment unlocks on its own
- Classic buttons remain an option
Every payment method in one list
Cards, wallets, buy now pay later, and offline methods all render as one set of cards.
- Selected method expands in place
- Gateway keeps its own fields
- Totals follow the choice
Returning customers pick an address
Signed-in customers see their Magento address book as cards, with the default already chosen.
- Native address book, restyled
- Default already selected
- Form hidden until needed
Built for the phone in your customer's hand
On a phone it becomes one fast column with the summary collapsed on top, one tap from the line items.
- Summary pinned on top
- Bottom sheet for line items
- Place Order stays in reach
Validation that points at the problem
Errors land next to the field that needs attention, and a decline shows the gateway message. Nothing already entered is lost.
- Field-level messages
- Gateway decline text kept
- Nothing to retype
Super compatibility
Keep every extension you already paid for
Every other one page checkout hands you its own copy of the checkout page, and that copy collides with your payment gateway, your shipping rules, and your next Magento upgrade. Ours restyles the native checkout instead of replacing it, so everything you run keeps working.
Four numbers that make the difference, straight from how the extension is built.
- 0Magento classes, routes, or templates replaced. It works through Magento's own plugin and mixin systems.
- 0Inline scripts, so the strict Content Security Policy from 2.4.7 stays on. Most one page checkouts break it.
- 100%Of payment forms still rendered by your gateway. We never touch certified payment markup.
- 1Setting to switch it off, and stock checkout returns byte for byte. Nothing is left behind.
What keeps working next to it
- Payment gatewaysCards, wallets, and buy now pay later keep their own components, hosted fields and 3-D Secure included.
- Shipping extensionsRate logic and required fields stay untouched, and auto-save waits for the validators they register.
- Tax enginesWe never touch quote calculation, so tax recalculation still fires on every address change.
- Address validationThe form keeps Magento's exact native fields, so validators hook in where they always did.
- Security toolsreCAPTCHA and two-factor flows use their native integration points.
- B2B and company accountsNo account management overrides, so company structures behave normally.
Before release we place real orders through Braintree wallets, CyberSource 3-D Secure, hosted redirect gateways, a ShipperHQ store, and a store running eight competing checkout mixins. On Hyvä Checkout it stays inactive.
