Love + War approached us with a series of technical bottlenecks that standard Shopify apps couldn't solve. As a high-volume brand, they were losing hundreds of hours to manual operational tasks and were limited by the platform's native architecture. Their three core challenges included:

1. Fragmented Returns Logistics: A complex "three-way" return flow between Shopify, Loop Returns (3rd party app), and an external warehouse. They lacked a centralized source of truth to manage inspections and multi-method refunds.

2. Architectural Limitations (Flattened Catalog): The brand utilizes a "flattened" catalog where colors are separate products. This prevented standard Shopify swatches from showing the full product line on collections and product pages.

3. Complex Bundle Logic: The need for pre-configured bundles that required real-time inventory checks for multiple sub-products and guaranteed discount application without third-party app bloat.

Case study: engineering solution and technical implementation

The Engineering (The Solution)

We stepped in as a long-term technical partner, building custom "invisible" infrastructure to bridge these gaps.

Automated Returns Ecosystem:
Using the Mechanic framework and Shopify webhooks, we engineered an automation engine that captures return data in real-time. We synced this to a custom Google Sheets "Control Center," allowing warehouse staff to trigger refunds or flag "Bad Returns" via custom scripts. The system then automatically executes refunds via the Shopify API based on the customer’s original payment method.
Cross-Product Swatch Engine:
We developed a high-performance JavaScript bridge using the Shopify Storefront API. By building a custom window data object at runtime, we cross-reference "flattened" product lines to inject dynamic color swatches into the UI. We implemented MutationObservers to ensure these swatches appear instantly, even on asynchronously loaded sections.
Custom Bundle PDP:
We architected a bespoke Product Detail Page (PDP) using Metafield mapping to link individual SKUs to a bundle "master" product. The system includes complex validation logic to verify stock levels for every item in the bundle before allowing the customer to add to cart, ensuring 100% fulfillment accuracy.
