Compocloset - Shopify Custom Functionality Building

Case Study: Shopify Custom Functionality Building

Compocloset is an eCommerce brand specializing in premium composting and waterless toilets designed for RVs, tiny homes, boats, and off-grid living. Built on Shopify, their website required custom-engineered functionality to support “complex product attributes, dynamic shipping rules, region-based pricing, integration” and more — going far beyond a standard theme customization. The project also included the implementation of multi-currency support to enhance the global shopping experience.

Project Details:

CompoCloset is an innovative brand offering compact, eco-friendly composting toilet systems designed for small homes, vans, off-grid living, and sustainable travel. Their Shopify store required more than a standard theme setup—CompoCloset needed custom-built functionality to support product education, configuration options, and a smooth purchasing experience for technical products.

This project focused on creating tailored features inside Shopify that would enhance user interaction, simplify product selection, and improve the overall usability of the store. These functionalities were developed to work seamlessly within the existing theme while maintaining strong performance and scalability.

Custom Product Configuration System

Because CompoCloset products include component variations, add-ons, and technical specifications, the standard Shopify variant system wasn’t enough.
So I developed a custom product configurator, which included:

  • Dynamic option selection (components, size, power options, extras).

  • Automated price adjustments based on selected add-ons.

  • Real-time visual or informational display updates as customers changed configurations.

  • Improved logic to prevent invalid or unavailable combinations.

This allowed customers to fully understand and customize their composting toilet setup without confusion.

Smart Add-On Bundling Functionality

To increase both usability and conversions, I built a smart add-on bundling system that:

  • Recommends compatible accessories (ventilation kits, spare parts, installation tools).

  • Auto-detects chosen product options and shows relevant bundles.

  • Adds multiple associated items to the cart in a single action.

  • Avoids duplicate items by using conditional cart rules.

This system significantly improved average order value and product discovery.

Technical Product Information Display

Eco-toilet systems require explaining airflow, power requirements, waste separation, installation steps, and maintenance needs.
To support this, I developed custom informational sections using Shopify’s flexible theme architecture:

  • Expandable/Collapsible technical tabs

  • Interactive comparison tables

  • Installation guidance blocks

  • Certification & compliance badges

  • FAQ automation using metafields

All content was built to be easily editable from the Shopify admin panel.

Custom Shipping Logic Integration

Because these products vary significantly in size, weight, and region-based shipping rules, I built custom logic that:

  • Calculates shipping rules based on product dimensions and destination.

  • Supports multi-item shipping with weight-based combinations.

  • Displays real-time messages about availability, delivery time, and international options.

This reduced customer support requests and improved checkout clarity.

Enhanced Cart & Checkout Experience

To optimize conversions for a high-consideration product, I implemented:

  • Custom cart drawer with detailed product breakdowns

  • Visual confirmation of selected options

  • “Before You Checkout” info blocks for shipping, warranty, and sustainability

  • Pre-purchase upsell modules

This ensured customers clearly saw what they were buying, reducing cart abandonment.

Performance Optimization for Custom Code

Because custom features can slow down Shopify stores, I performed:

  • Modular JS development

  • Deferred script loading

  • Liquid logic optimization

  • Removal of unused theme assets

  • Compression of product media

  • Lazy-loading for custom components

This ensured the added functionalities did not compromise page performance.

Final Outcome

The custom-built functionalities significantly improved CompoCloset’s Shopify store by making it more intuitive, educational, and conversion-friendly. The new features enabled customers to configure high-tech products confidently while maintaining a clean, modern, and fast-loading site.
