Refactor+ Shopify Demo Store: Engineering in Action

Introduction

Since most of our enterprise projects are delivered under strict NDAs, we created this custom-built Shopify demo store to demonstrate how we approach large-scale ecommerce development.

The store was developed entirely from scratch, following the same architectural standards we apply to enterprise Shopify builds. The goal was simple: showcase the level of flexibility, performance, and scalability that modern Shopify stores require when supporting large product catalogues, marketing campaigns, and growing teams.

The Challenge

Most of our enterprise Shopify projects are protected by NDAs, which makes it difficult to publicly demonstrate the scale, architecture, and advanced functionality we typically deliver. We needed a way to showcase our development standards, UX thinking, and technical capabilities without exposing client projects.

The Solution

We built a fully custom Shopify demo store from scratch, replicating the type of architecture and functionality we usually deliver for enterprise brands. The project demonstrates advanced navigation, dynamic product experiences, modular homepage sections, high-performance search, custom cart logic, and scalable content systems - all built following Shopify best practices.

Homepage

The homepage was designed as a modular system of Shopify sections, allowing marketing teams to build new layouts without developer involvement.

Each slide of the hero banner can support images or videos, separate media for desktop and mobile, different alignment options for text and buttons, autoplay controls, and multiple pagination styles.

Beyond the hero section, the homepage includes several editorial-style content blocks. A split-screen module allows two parallel stories or promotions to run side by side, each with independent media, messaging, and positioning.

Also, it includes sections that combine visual storytelling with conversion-focused elements, such as an image-driven signup block for capturing leads while maintaining a strong brand aesthetic.

Everything from spacing and typography to slider behaviour and product assignments can be controlled directly in the Shopify Theme Customiser, meaning most homepage updates can be handled by the internal team without developer assistance.

Navigation

For large stores, navigation plays a critical role in both product discovery and promotional strategy.

The desktop menu was developed as an advanced multi-level mega menu that supports up to three levels of navigation. In addition to standard category links, the menu can also contain promotional content blocks with images, headings, and campaign links.

Both desktop and mobile menus are lazy-loaded, reducing the initial page load and improving performance.

Search Experience

Search was designed as a global modal experience, meaning customers can start searching from anywhere in the store without navigating to a separate page.

When opened without a query, the search modal shows curated starter content such as popular searches, trending products, and highlighted categories. This helps guide users even before they begin typing.

As soon as a customer starts entering a query, the system performs live asynchronous search requests, displaying product results, related categories, and updated suggestions in real time.

On desktop, results appear in parallel panels, while mobile users interact with tabbed results for a cleaner interface.

Skeleton loaders and blur transitions ensure the search experience feels smooth and responsive rather than disruptive.

Product Listing Pages

The product listing architecture supports two different collection modes, depending on the merchant’s needs.

The first option uses Shopify’s native filtering and sorting system, enhanced with a custom interface. This provides reliable catalogue browsing with asynchronous filtering, responsive product grids, and URL-based filter states that allow links to be shared.

For stores with more complex merchandising requirements, the second option integrates Boost AI Search & Filter. This version allows the product grid to contain non-product content blocks directly within the catalogue.

Filters support multiple display formats, including lists, tiles, colour swatches, and price range sliders, with multilingual support through metaobjects.

Product Detail Pages

The product detail page was designed to handle the type of variant complexity often found in enterprise stores.

Variant selectors support both colour swatches and image-based selections. The system dynamically updates pricing, discount labels, product media, and availability messages whenever the customer changes variants.

The page also supports extended selling scenarios, such as pre-orders or backorders, where variants remain purchasable even when inventory reaches zero.

A Product Details Slider provides an editorial breakdown of the product using synchronised image and text slides.

Another section, called Complete the Look, allows brands to present product bundles visually using interactive hotspots that link directly to related items.

Support Hub

To reduce customer support workload, we developed a structured support hub built entirely from modular Shopify sections.

The hub includes a central landing page with search functionality, quick navigation blocks for key services, and popular FAQ content displayed in expandable accordion sections.

Unlike many Shopify stores where FAQs are stored as static page content, this system uses structured metaobjects, allowing questions and answers to be grouped into categories and easily maintained over time.

Customers can search the knowledge base, browse articles, or navigate directly to specific topics through sidebar menus on individual FAQ pages.

Cart Experience

Instead of redirecting users to a separate cart page, the store uses a side cart drawer that appears as a slide-out panel.

Customers can update quantities, switch variants, remove items, apply discount codes, and view free shipping progress without leaving their current page.

The cart is built on Shopify’s AJAX cart APIs, allowing partial UI updates rather than full page reloads. Only the affected parts of the cart interface refresh, making the experience faster and smoother.

The cart also integrates product recommendations and wishlist interactions, allowing customers to move items between lists and cart with minimal friction.

Performance & Scalability

Performance was treated as a core requirement rather than an afterthought.

The theme architecture focuses heavily on Core Web Vitals optimisation, including deferred JavaScript loading, lazy-loaded media, and modular section architecture to avoid large monolithic scripts.

Search results are cached within the session to reduce repeat queries, navigation components are loaded on demand, and cart updates only refresh the parts of the interface that actually change.

These optimisations ensure the store remains fast and responsive even as features and content scale.

The Results

The project resulted in a fully functional enterprise-grade Shopify demo store that demonstrates the development standards we typically deliver for large ecommerce brands. It showcases advanced UX patterns, scalable theme architecture, and high-performance storefront behaviour - all built following Shopify best practices.

The demo allows potential clients and partners to clearly understand the depth of our Shopify expertise, from complex navigation and merchandising systems to dynamic product experiences, modular content management, and performance optimisation.
