Shopify experts for UK businesses

Whether you are launching your first Shopify store, replatforming from Magento or WooCommerce, or scaling on Shopify Plus, our UK-focused team delivers the strategy, design, development and growth marketing you need under one roof. We work with direct-to-consumer brands across fashion, beauty, homeware, food and drink, sport and B2B wholesale.

Built for selling in the UK

Every store we build is set up for the realities of UK ecommerce from day one:

  • VAT-ready pricing - VAT-inclusive prices, correct tax settings and clear invoices, plus Shopify Markets for selling into the EU and the US.
  • UK GDPR and PECR compliance - consent-friendly cookie set-ups, privacy-first analytics and compliant email sign-up journeys.
  • Payments UK shoppers trust - Shop Pay, Apple Pay, Google Pay, PayPal and buy-now-pay-later options such as Klarna and Clearpay.
  • UK delivery integrations - Royal Mail, DPD, Evri and click-and-collect options, with accurate delivery estimates at checkout.
  • Fast, mobile-first performance - lightweight themes optimised for Core Web Vitals, because most UK ecommerce traffic is on mobile.

Working on UK time

Our team is split between India and the USA, which means your project is covered throughout the UK business day. Morning calls are handled by our India team, and afternoon and evening hand-overs by our US team - so questions get answered quickly and work keeps moving overnight. You will have a dedicated project manager, a shared Slack or Teams channel and regular video calls.

How a UK Shopify project works

  1. Discovery - we audit your current store, analytics and competitors and agree goals, scope and a fixed-price proposal.
  2. UX and design - wireframes and high-fidelity designs in Figma, reviewed with your team.
  3. Shopify development - Online Store 2.0 theme development, app integrations and data migration.
  4. QA and launch - device testing, speed and SEO checks, redirect mapping and a carefully managed go-live.
  5. Growth - ongoing CRO, SEO, email marketing and support on a flexible monthly retainer.

Partners

We build on Shopify, WordPress & modern frameworks - with the very best technology partners.

With thousands of apps in the Shopify App Store, choosing the right technology for your business can be a challenge. We've partnered with world-leading Shopify Plus technology partners and apps to help brands build efficient, scalable ecommerce stores - and we help you choose the right stack, not just the most popular one.

From reviews, loyalty and subscriptions to helpdesk, analytics, ERPs and back-end integrations, our experience helps you make the right technology decisions. Where needed, we design and build custom integrations so every tool works seamlessly with your brand and your store. For India-focused brands we integrate payments and checkout with Razorpay, PhonePe and GoKwik, WhatsApp marketing with KwikEngage, reviews with Judge.me and shipping with Shiprocket and Delhivery - and on WordPress we build with WooCommerce, Elementor and Yoast SEO.
