Customize checkout through Shopify Checkout Extensibility without maintaining custom checkout code.

AVAILABLE
Checkout Extensibility without a custom checkout codebase.
Shopify Plus merchants want banners, cart edits, fields, and payment rules on Plus checkout. Checkout Blocks does that through Extensibility — not a maintained theme fork.
The last step is still a brand surface.
A generic Plus checkout leaves conversion and compliance details on the table. Blocks let the merchant shape the step without hiring checkout engineers.
Install on the Plus store
The app is free on the Shopify App Store and uses Checkout Extensibility. No custom checkout code to own.
Configure the surfaces that matter
Add banners, allow cart edits, show discount codes, collect fields, and set payment rules from the editor.
Watch the step that decides the order
Adjust offers and trust messages where buyers hesitate, without opening a development ticket for every copy change.
Banners & trust messages
Promotional and reassurance content where Plus buyers actually decide.
Checkout cart editing
Quantity, remove, and variant changes happen in checkout — not only in cart.
Custom fields
Collect GST, VAT, notes, and other details with conditional logic.
Payment option rules
Hide or reorder methods using logic on the order or customer — still inside Extensibility.
Plus checkout you can actually edit
Merchants change the last step without a custom checkout repo.
Fewer abandoned ‘I need to change that’ exits
Cart editing keeps the buyer in checkout.
Required details before the charge
Fields collect what finance and ops need on the same step.
You run Shopify Plus and want Checkout Extensibility customization without custom checkout code.
Buyers currently leave checkout to fix the cart or hunt a discount.
You need banners, fields, and payment rules in one free app.
Someone on commerce or ops can own the editor after install.
