About This Service

Shopify Stores Engineered for Conversion, Scale, and Speed

Shopify powers over 10% of global e-commerce — but most stores never reach their commercial potential because they are built for launch, not for growth. Template themes, slow page speeds, weak PDP structure, and checkout friction are left unfixed while ad spend scales and conversion stays flat.

We build Shopify stores as conversion systems — custom themes built from scratch or purpose-built on the fastest available foundations, with every PDP, collection, and checkout element designed around buying psychology and validated UX patterns. We optimise for Lighthouse scores, Core Web Vitals, and mobile-first performance from the first commit.

Our Shopify builds integrate your full commerce stack — ERP, WMS, CRM, marketing automation, and loyalty platforms — so inventory, orders, and customer data flow without manual reconciliation. We have delivered Shopify stores across DTC fashion, homewares, food and beverage, and B2B wholesale.

  • Custom Shopify themes — pixel-perfect, Lighthouse 90+, mobile-first
  • Full stack integration — ERP, WMS, CRM, marketing tools wired correctly
  • Shopify Plus capabilities — scripts, functions, checkout extensibility
  • Multi-market support — multi-currency, multi-language, B2B price lists

Multi-Currency & Global Selling

Regional payment gateways, localised shipping rules, and Shopify Markets for seamless international commerce.

App & API Integration

Deep integration with CRM, ERP, inventory systems, and 6,000+ Shopify apps via custom Storefront APIs.

Platform Migration to Shopify

Zero-downtime migrations from Magento, WooCommerce, or any platform — full SEO and data integrity preserved.

Custom checkout flows, one-click upsells, and PCI-DSS compliant payment integration for higher AOV.

Shopify Plus Enterprise

Advanced automation, B2B portals, custom storefronts, and high-volume features for scaling enterprise brands.

Real-World Impact

Use Cases in Production

Real deployment patterns — the specifics vary per client, but the structure stays the same.

DTC Brand Migration and Custom Theme BuildFashion & Apparel

DTC Brand Migration and Custom Theme Build

The Challenge

A UK fashion brand with £8M revenue was on a generic Shopify theme that was slow, visually generic, and not converting on mobile. Mobile traffic was 74% of sessions but only 41% of revenue. They also had no proper size guide, no outfit recommendations, and a four-step checkout.

The Solution

Custom Shopify theme built on Shopify CLI with Dawn architecture as the foundation. Mobile-first PDPs with integrated size guide, lookbook-style cross-sell, and product video. Checkout optimised to two steps. Integrated with Klaviyo, Gorgias, and Yotpo from launch.

Outcomes
  • Mobile conversion rate from 1.2% to 2.6% within 60 days
  • Page load time from 4.8s to 1.4s on mobile
  • £1.2M additional revenue attributed to conversion uplift in year one
Multi-Market Shopify Plus ExpansionHomewares

Multi-Market Shopify Plus Expansion

The Challenge

A homewares brand was running separate Shopify stores for UK, EU, and US — each manually maintained, with different product catalogues, inconsistent branding, and no shared customer data. The operations team was managing three stores like three separate businesses.

The Solution

Shopify Plus Markets implementation consolidating three stores into one. Unified product catalogue with market-specific pricing, currency, and localised content. Single Shopify admin, shared customer profiles, and one integration point to the ERP and WMS.

Outcomes
  • Operations team saved 22 hours per week in cross-store admin
  • Customer data unified — loyalty and retention campaigns now cross-market
  • EU market revenue up 34% in the 6 months following consolidation
Shopify B2B Wholesale PortalB2B

Shopify B2B Wholesale Portal

The Challenge

A manufacturer was managing B2B wholesale orders via email and spreadsheets. Their retail stockists had no self-service ordering, no account visibility, and constant back-and-forth with the sales team on minimum orders, lead times, and invoice status.

The Solution

Shopify Plus B2B with custom wholesale portal — account-specific pricing, minimum order quantities, net payment terms, order history, invoice downloads, and a re-order feature. Integrated with Xero for invoice management and the WMS for real-time stock availability.

Outcomes
  • B2B order processing time reduced by 80% — from email to self-service
  • Wholesale revenue grew 28% as stockists ordered more frequently
  • Sales team freed from order admin — redirected to new account acquisition
