Shopify Theme Development

Shopify theme development for a luxury jewellery store

A respected UK jeweller needed a new digital foundation. Their previous E-Commerce platform struggled with performance, offered little flexibility for the marketing team, and lacked integration with finance options and CRM workflows. The goal was clear: build a refined platform that looked exceptional, loaded fast, and connected to the finance and CRM tools behind the scenes.

How it was built

Custom Shopify Plus theme

With a design partner, I built a bespoke Shopify Plus theme on the Online Store 2.0 framework. Every component - from hero banners to product carousels - was modular, enabling marketing teams to build and update content directly from the admin panel.

Tailwind CSS ensured visual consistency across all templates, while a structured component library simplified future maintenance.

CRM & finance integrations

The new platform connected directly to HubSpot CRM, automatically recording form submissions, finance applications, and order data. This gave the sales team a single source of truth for customer interactions and improved follow-up accuracy.

Finance options from V12 and Novuna were integrated at the product and checkout stages, allowing customers to explore flexible payments without leaving the site.

Product presentation & experience

Luxury products demand confidence. I implemented responsive image galleries, zoom-in functionality, and high-definition video to showcase craftsmanship in detail. Product pages included care guides, warranty information, and delivery options to support the customer’s decision-making process.

Performance & reliability

Cloudflare CDN, image optimisation and script minimisation keep the site fast. A rigorous QA and testing cycle ensured reliability under high-traffic conditions, and the site has handled seasonal traffic without issues.


Lessons learned

Luxury retail demands more than aesthetics - it requires the technology to match. Combining Shopify Plus flexibility with CRM and finance integrations delivers clear operational benefits without compromising design.

Modular sections let the marketing team launch campaigns without waiting for a developer, and the speed work helps every step from browsing to checkout.
