Checkout Extensibility

Shopify killed checkout.liquid. Most agencies are still pretending it did not happen.

Before: You had checkout.liquid — a messy but flexible way to customize your Shopify checkout. Order bumps, custom fields, trust badges, loyalty redemption — all hacked together with Liquid code. Then Shopify deprecated it and introduced Checkout Extensibility. A better system, honestly. Faster, more secure, upgrade-safe. But it requires a completely different approach to build.

Bridge: Most agencies have not caught up. They are still trying to use workarounds, third-party scripts, and apps that break with every Shopify update. Meanwhile, Checkout Extensibility lets you build native checkout customizations — order bumps, custom fields, delivery instructions, loyalty point redemption, branded UI — that run inside Shopify's infrastructure and never break on updates.

After: Your checkout looks and works exactly the way your brand needs. Order bumps that actually display. Custom fields that capture the data you need. Trust badges and payment icons where customers expect them. All built with Checkout UI Extensions that Shopify officially supports. No more duct tape. No more broken checkouts after platform updates.

Revenue Driven

Your checkout is either broken or basic. Neither is acceptable.

  • Checkout.liquid customizations broke after the latest Shopify update and nobody can fix them
  • No order bumps or upsells at checkout because your current setup does not support them
  • Third-party checkout scripts slow down your page and create security warnings
  • Cannot add custom fields, delivery notes, or gift messages at checkout
  • Your checkout looks generic — no brand colors, no trust elements, no personality

The checkout is where revenue happens. A broken or generic checkout page is costing you money on every single order.

What we do for Global brands

Checkout UI Extensions

Native Shopify checkout customizations built with Checkout Extensibility. Branded visuals, custom banners, trust badges, and payment icons that never break on Shopify updates.

Order bumps and checkout upsells

One-click additions at the checkout stage. Complementary products, warranty add-ons, gift wrapping — placed where acceptance rates are highest.

Custom checkout fields

Delivery instructions, gift messages, custom engraving text, company name for B2B — whatever data your business needs captured at checkout, built natively.

Loyalty redemption at checkout

Points balance display and one-click redemption integrated directly into the checkout flow. No redirects, no separate pages, no friction.
