Service Overview

Every extra second of product page latency or unnecessary checkout field directly costs UK retailers thousands of pounds in abandoned baskets. At 360 Web Coders in Wallington, Surrey, our ecommerce web development service engineers high-velocity online stores built specifically around conversion psychology, Average Order Value (AOV), and back-office automation. Because we are platform-agnostic masters across Shopify Plus, custom WooCommerce, Magento 2 (Hyva), and headless Next.js commerce, we recommend and architect the exact stack that fits your SKU count, B2B/D2C margin structure, and ERP ecosystem. From instant Algolia faceted search and dynamic bundle builders to Apple Pay/Klarna one-click checkouts and automated Royal Mail, DPD, and 3PL warehouse dispatch, we build resilient UK retail engines that scale effortlessly through peak Q4 trading.

ECOMMERCE DEV FAQ

Ecommerce Web Development FAQs

Detailed answers on UK eCommerce development costs, choosing between Shopify, WooCommerce, and Magento, and ERP integrations.

Ecommerce web development in the UK costs between £3,500 and £9,000 for bespoke D2C Shopify or WooCommerce stores, £9,000 to £25,000 for custom multi-currency stores with ERP/EPOS integration, and £25,000 to £75,000+ for enterprise B2B portals, Magento 2 builds, or multi-vendor marketplaces.

We recommend Shopify / Shopify Plus for fast-scaling D2C and hybrid B2B brands wanting zero server maintenance; custom WooCommerce for content-rich brands needing complete PHP flexibility; and Magento 2 (Hyva) or Headless Next.js for complex multi-warehouse B2B catalogues with 50,000+ SKUs.

A bespoke D2C eCommerce store takes 5 to 8 weeks to design, build, populate, and test. Enterprise B2B eCommerce platforms involving custom trade pricing rules, ERP middleware, and historical data migration take 10 to 16 weeks.

Yes, we integrate Loqate/Ideal Postcodes address lookup, live shipping rates and label generation for Royal Mail, DPD, DHL, and Evri, and real-time inventory sync with Linnworks, Brightpearl, Mintsoft, and ShipStation.

We engineer automated JSON-LD Product, Offer, AggregateRating, and BreadcrumbList schema, clean canonical faceted filter URLs, sub-second Core Web Vitals, and automated Google Merchant Center XML feeds.

Yes, all payment processing uses tokenized PCI-DSS Level 1 gateways (Stripe, Shopify Payments, Adyen, Worldpay) with 3D Secure 2 (SCA) authentication, TLS 1.3 encryption, and UK GDPR-compliant customer data controls.
