Is Your Shopify Development Costing You Customers Every Day?

02 / Built around your ambition
Our custom Shopify website development services — 8 Proven Solutions
- 01
Custom Shopify Liquid theme development
We build Online Store 2.0 themes in Liquid from your designs, with flexible sections and blocks so merchandisers can launch campaigns without a developer.
- 02
Shopify Plus migration and customisation
We plan and run moves to Shopify Plus, then configure scripts, Functions, Launchpad and expansion stores to use the features your plan now pays for.
- 03
Hydrogen + Oxygen headless storefronts
We build React storefronts on Hydrogen and deploy them to Oxygen, pairing Shopify's checkout and catalogue with a fully custom, fast front end.
- 04
Shopify app development and integration
We develop private and public Shopify apps and connect third-party services through the Admin and Storefront APIs, replacing brittle workarounds with maintained code.
- 05
Checkout extensibility on Plus
We use Checkout UI extensions and Shopify Functions to add custom fields, discounts, delivery rules and upsells inside the upgrade-safe Plus checkout.
- 06
Performance and app stack pruning
We audit every installed app, remove those that duplicate theme features or add little value, and tune images and scripts to lift Lighthouse scores and reduce monthly spend.
- 07
B2B on Shopify Plus B2B
We configure company profiles, catalogues, price lists, payment terms and quick order forms in Shopify Plus B2B so wholesale and retail run from one admin.
- 08
Migration from WooCommerce/Magento/Wix
We migrate products, customers, order history and URLs from WooCommerce, Magento or Wix, with 301 redirects mapped so search rankings carry over to the new store.
The Payoff
What You Gain From Our Shopify Website Development
A theme built around your products
A custom Liquid theme carries only the sections your catalogue needs, without the bloat of marketplace themes.
Checkout that reflects your brand
Checkout extensions add upsells, delivery options and custom fields within what your Shopify plan allows.
Shopify connected to your back office
Inventory, fulfilment and customer data sync with your ERP or warehouse system through reliable integrations.
A clear path to headless if you need it
When a Hydrogen storefront makes sense, we build it on the same Shopify back end your team already knows.
How we work / From idea to impact
Our Shopify Website Development Process
- 01
Store audit
We review your current theme, installed apps, checkout setup and speed data to see what is helping and what is holding the store back.
- 02
Plan and app decisions
We decide which features belong in the theme, which need an app and whether your Shopify plan supports the checkout changes you want.
- 03
Theme design
Templates for collections, products, cart and content pages are designed as reusable sections your team can edit in the theme editor.
- 04
Liquid and app development
We build the theme, any custom Shopify app and the integrations, working in a development store so your live shop is untouched.
- 05
Data migration and QA
Products, variants, customers and redirects are imported and checked, then checkout is tested with real payment methods.
- 06
Launch and handover
We switch the theme live, monitor orders closely for the first days and train your team on managing sections and content.

Contact usCustom Shopify Website Development Services for Growing Businesses
Custom Shopify website development services are the highest-volume engagement type in ecommerce in 2026 — and for good reason. Shopify and Shopify Plus dominate the DTC market because the platform handles the most painful parts of running an online store (hosting, security, PCI compliance, app ecosystem, predictable performance) better than any competitor. We build, optimise and migrate Shopify stores for DTC fashion brands, supplement companies, beauty retailers, consumer electronics, and increasingly B2B sellers on Shopify Plus B2B. Every Shopify engagement starts with a 90-minute audit covering theme code quality, app stack costs, catalogue structure, checkout funnel and performance metrics. From there we recommend the right path: a fresh custom theme build, an existing theme rebuild, an app stack prune, a Plus migration, or a Hydrogen headless storefront. We are fluent in Liquid, Shopify Functions, the Shopify CLI, Hydrogen + Oxygen, Shopify Markets for international, and Shopify Plus B2B. Every store we ship targets Lighthouse 90+ mobile, full Product/Offer/Review schema, Core Web Vitals pass, and a checkout funnel optimised against industry-leading conversion benchmarks. We also handle migrations from WooCommerce, Magento and Wix to Shopify with full SEO redirect mapping, customer/order/product data carry-over, and minimal launch downtime.
