Best Ecommerce Agencies in the UK
Selling online well needs more than a general web designer - platform choice, checkout flow, product data and marketplace strategy all shape whether people actually buy. Ecommerce agencies specialise in Shopify, Magento, WooCommerce and similar platforms, building stores that handle payments, stock and shipping properly, and often run the ongoing marketing (paid, SEO, email) needed to drive sales once the store is live.

What is Ecommerce?
Ecommerce agencies focus specifically on online stores rather than general websites, covering platform selection and build (Shopify and Shopify Plus, Magento/Adobe Commerce, WooCommerce, BigCommerce), product catalogue structure, checkout and payment gateway setup (Stripe, PayPal, Klarna), and integrations with stock, fulfilment and accounting systems. Many also run marketplace strategy - listing and optimising products on Amazon, eBay or Etsy, managing Amazon Advertising, and handling the different rules each marketplace imposes. Beyond the build, ecommerce agencies often run conversion-focused work unique to online retail: cart abandonment recovery, product page optimisation, merchandising and cross-sell logic, and channel marketing (Google Shopping, paid social) aimed specifically at driving transactions rather than general brand awareness.
Why Hire a Ecommerce Agency?
- Platform expertise in Shopify Plus, Magento/Adobe Commerce or WooCommerce, not a generic CMS build
- Checkout and payment gateway setup handled properly, including Klarna, Apple Pay and multi-currency where relevant
- Marketplace strategy and listing optimisation for Amazon, eBay or Etsy alongside your own store
- Product catalogue and merchandising structure built for browsing and cross-sell, not just a product list
- Integration with stock, fulfilment, ERP or accounting systems so the store isn't a manual data silo
- Ecommerce-specific marketing (Google Shopping feeds, cart abandonment flows, product-level SEO)
Frequently Asked Questions
How much does an ecommerce website cost in the UK?
A straightforward Shopify store build typically costs £3,000-£10,000. More complex builds with custom functionality, third-party integrations or Shopify Plus start around £15,000 and can reach £50,000+ for large catalogues or bespoke checkout requirements. Magento/Adobe Commerce builds tend to start higher, from £20,000, given the platform's complexity. Ongoing ecommerce marketing retainers (Google Shopping, paid social, CRO) typically run £1,500-£6,000 a month on top of the build.
Should I choose Shopify, Magento or WooCommerce?
Shopify suits most small-to-mid sized retailers wanting a fast, reliable build with lower ongoing maintenance. WooCommerce is a reasonable budget option if you're already invested in WordPress. Magento (Adobe Commerce) generally makes sense for larger, more complex catalogues or B2B/B2C hybrid stores needing deep customisation, but it costs more to build and maintain. A good ecommerce agency should ask about catalogue size, growth plans and integrations before recommending a platform, not push whichever one they're set up to build.
How long does an ecommerce build take?
A standard Shopify store typically takes 6-10 weeks from kick-off to launch. More complex builds with custom integrations, large product catalogues or marketplace connections can run 3-6 months. Migrating from an existing platform (say WooCommerce to Shopify Plus) usually adds time for data migration and testing, so build in extra weeks for stock, order history and SEO redirects to be handled properly.
Do I need a separate agency for Amazon and my own website?
Not necessarily - many ecommerce agencies handle both, but marketplace work (Amazon SEO, Amazon Advertising, listing compliance) is a genuinely different skillset from running your own store, so check the agency has specific marketplace experience rather than treating it as an afterthought. Some businesses do use a specialist Amazon agency alongside a separate one for their own site, particularly once Amazon becomes a significant revenue channel.
