Platform: Shopify (Extension-Only Apps)
Services: Custom App Development · Checkout Extensibility · Performance Optimization

Small apps, big impact — native Shopify extensions that sell more.

Challenge

Most merchants rely on third-party Shopify apps — which often slow down stores and add unnecessary complexity.

Our mission? Build custom, native Shopify extensions that integrate seamlessly with checkout, cart, and product logic — no bloat, no external scripts, just clean functionality.

We partnered with multiple Shopify Plus brands that needed conversion-focused micro-features not covered by existing apps.

Each request had its own challenge:

• Buy X for $Y — create dynamic pricing logic across selected product groups using metafields.
• Shipping Protection Add-on — auto-calculate protection fee based on cart subtotal.
• Thank You Page Survey — collect post-purchase insights directly in checkout.
• Subscription Widget — enable subscription toggle logic per market (default ON for the U.S.).

Plan

The plan was simple: use Shopify’s new Checkout Extensibility and Cart Transform APIs to build modular extensions that:

• Load instantly with zero third-party dependencies
• Integrate natively with the Shopify checkout flow
• Are fully managed through the Shopify admin interface
• Work seamlessly with existing storefront logic

The goal was to keep stores lightning-fast — while giving them the same power custom apps offer.

Solution

We developed four separate extension-only apps, each tackling a specific use case merchants needed, without relying on traditional app embeds or liquid hacks.

1. Buy 2 for $70 (Cart Transform)
   Custom pricing logic that applies a fixed bundle discount when customers add qualifying products (with a specific metafield). The cart auto-adjusts totals dynamically — no code, no theme edits.
2. Custom Shipping Protection (Dynamic % Fee)
   Adds a calculated line item based on cart subtotal (e.g., 3% of total) — integrated directly in the checkout UI with transparent price breakdown.
3. Thank You Page Survey (Post-Purchase Extension)
   Collects customer feedback directly on the order confirmation page — tied to the order ID and synced to analytics via webhook.
4. Subscription Widget (Localized Logic)
   Displays a smart widget on product pages for subscription-based products, enabled by default for the U.S. market, with an option for customers to toggle it off before checkout.

Each app does one thing, perfectly — built to feel native, not installed.

Execution

All four apps were built using:

• Shopify’s App Bridge + Checkout UI Extensions
• Cart Transform APIs for pricing logic
• Shopify Functions for speed and flexibility
• Metafields for merchant-level configurability

We deployed them through Shopify’s CLI with custom manifests, ensuring no theme changes or asset injection.
Each extension was tested in live merchant environments to ensure zero checkout slowdowns and 100% theme compatibility.

Results

• Zero impact on storefront performance
• Native integration through Shopify Admin
• Real customer insights via Thank You Page surveys
• Increased AOV (Average Order Value) via upsell and bundle logic
• Market-specific UX (custom subscription logic for U.S. region)

It’s the small details that make the biggest difference — especially when they don’t slow your store down.
