Service Overview

Winning in the competitive UK direct-to-consumer (D2C) and wholesale eCommerce market demands a storefront that loads instantaneously and removes every ounce of checkout friction. At 360 Web Coders in Wallington, Surrey, our Shopify web development team engineers high-converting Shopify and Shopify Plus stores tailored to British retail brands. We build custom Online Store 2.0 Liquid themes, headless Hydrogen and Oxygen storefronts, and private Shopify Apps using Node.js and GraphQL Admin APIs. Instead of slowing your store down with twenty conflicting monthly subscription apps, we code native bundle builders, tiered B2B wholesale pricing, multi-currency Shopify Markets setups, and Checkout UI Extensions directly into your architecture. We also connect Shopify seamlessly with UK 3PL fulfilment warehouses, Brightpearl, Linnworks, Xero, and Klaviyo.

SHOPIFY DEV FAQ

Shopify Web Development FAQs

Practical answers on UK Shopify and Shopify Plus build costs, custom apps, Magento/WooCommerce migrations, and speed tuning.

Custom Shopify web development in the UK costs between £3,500 and £8,500 for a bespoke Online Store 2.0 theme build, £8,500 to £20,000 for complex stores with custom bundle logic and ERP integrations, and £20,000 to £55,000+ for enterprise Shopify Plus builds.

A bespoke Shopify store takes 4 to 8 weeks to design, engineer, and launch, while a full Shopify Plus migration from Magento or WooCommerce with ERP sync takes 8 to 14 weeks. We stage the entire build in a sandbox store so your live sales are never interrupted.

Yes, we handle complete migrations of products, variants, customer accounts, historical orders, reviews, and blog content while implementing a verified 1-to-1 301 redirect matrix so your UK organic rankings and backlinks transfer intact.

Third-party Shopify apps inject heavy external JavaScript that hurts mobile conversion rates. We replace bloated subscription apps by coding native Liquid features, such as free-shipping progress bars, product bundles, size guides, and back-in-stock alerts, directly into your theme.

Yes, our backend team builds custom Shopify apps using the GraphQL Admin API and webhooks to automate inventory, order routing, and VAT invoicing with Brightpearl, Linnworks, NetSuite, Xero, Sage, and UK 3PL fulfilment partners.

Yes, we integrate Shopify Payments, Apple Pay, Google Pay, Klarna, Clearpay, and PayPal alongside Shopify Markets multi-currency rules and B2B wholesale trade portals with tiered volume discounts.
