Ecommerce Web Design for UK Businesses
Ecommerce web design is the planning, design and build of an online shop: the catalogue structure, product pages, basket, checkout, payments, delivery options and the systems behind them. Good ecommerce design is measured in sales rather than looks. It makes products easy to find, answers buying questions before they're asked, and removes friction from checkout.
Webgenix is a web design and development agency based in Derby that builds online stores for businesses across the UK on Shopify, WooCommerce and custom Laravel platforms.
What Does Ecommerce Web Design Include?
An online store is five connected systems. Each one can cost you sales if it's treated as an afterthought.
Store Architecture & Navigation
Categories, collections and filters organised around how customers shop, not how your stock spreadsheet is laid out. This is also what shapes your category URLs, which matters for SEO.
Product & Category Pages
Photography layouts, variant selectors, stock and delivery messages, size guides and reviews, placed where they answer the question that's stopping the purchase.
Basket & Checkout
A short, mobile-first checkout with guest purchase, clear delivery costs before the final step, and express payment options such as Apple Pay and Google Pay where the platform supports them.
Payments, Delivery & VAT
Payment gateways such as Shopify Payments, Stripe and PayPal, UK and international delivery zones, and VAT-inclusive consumer pricing set up correctly from day one.
Integrations
Connections to accounting (e.g. Xero, QuickBooks), stock, shipping labels, email marketing and marketplaces, so orders don't need re-keying by hand.
SEO & Analytics
Product structured data, crawlable category pages, redirects from any old store, and ecommerce tracking in Google Analytics 4 so you can see which products and channels actually sell.
Shopify, WooCommerce or Custom: Which Suits Your Business?
There's no universally "best" ecommerce platform. The right one depends on who will run the store, what you sell and how much control you need.
How the three approaches compare for a typical UK small or medium business Shopify WooCommerce Custom build What it is Hosted ecommerce platform (software as a service) Free, open-source ecommerce plugin for WordPress A store application built for you, e.g. on Laravel Running costs Monthly subscription, plus paid apps; extra transaction fees apply if you don't use Shopify Payments Hosting, domain and any premium extensions; payment gateway fees Hosting and ongoing development/support Hosting, security & updates Handled by Shopify Your responsibility (or covered by a care plan) Your responsibility (or covered by a care plan) Flexibility High within Shopify's rules; some URL and checkout limits Very high; full access to code and database Unlimited: built to your exact process Best for Retailers who want to focus on selling, not maintaining software Content-led brands, unusual pricing rules, existing WordPress sites Complex B2B ordering, configurators, marketplace or portal-style stores
When Shopify is the right choice
You want a dependable store without thinking about servers, security patches or plugin conflicts, and you're comfortable paying a monthly subscription for that. Shopify is especially strong if you also sell in person, because its POS shares stock with the online store. See how we approach Shopify store design.
When WooCommerce is the right choice
You want to own the whole site on your own hosting, publish a lot of content alongside your products, or need product types and pricing rules (trade pricing, bookings, bundles) that a hosted platform makes awkward. Read about our WooCommerce development work.
When you need a custom build
Your ordering process is the product: customer-specific catalogues, quote-to-order workflows, complex configurators or deep integration with internal systems. Here an off-the-shelf platform becomes a workaround. See our custom web development service.

What Makes an Online Store Convert?
Most lost sales happen in small moments: a slow product page on mobile data, delivery costs that only appear at the last step, a forced account sign-up, or a returns policy nobody can find. Conversion-focused design removes those moments one by one.
Speed on real phones
Shoppers browse on mobile, often on patchy connections. We keep themes lean, compress and correctly size images, and limit the apps and scripts that slow stores down. Our website speed optimisation work is built into every store we launch.
Answers before questions
Delivery times, returns, sizing, materials and stock levels belong on the product page, not buried in a footer link. When the answer is visible, the customer doesn't leave to go and look for it.
Trust signals that matter
Clear contact details, genuine reviews, recognisable payment options and a visible returns policy do more for a new store than any badge. For a smaller brand, a real "about us" story matters too.
A shorter checkout
Guest checkout, address lookup, express wallets and delivery costs shown early all reduce abandonment. On Shopify much of this is standard. On WooCommerce we configure it deliberately.
Measuring what happens
GA4 ecommerce events show where shoppers drop out: product view, add to basket, checkout or payment. That turns guesswork into a prioritised list of fixes. Our guide to ecommerce conversion rate optimisation goes deeper.
How Much Does an Ecommerce Website Cost in the UK?
Webgenix builds Shopify and WooCommerce stores from £2,500, on a fixed-price quote. That covers a professionally designed store with your products set up, payments and delivery configured, on-page SEO and a training walkthrough. What moves the price above that starting point is scope, not surprises:
| Cost driver | Why it affects the price |
|---|---|
| Catalogue size & variants | Hundreds of products, or products with many size/colour/material combinations, take longer to structure, import and check. |
| Custom design | Every store gets its own theme rather than a reskinned template. The number of distinct page layouts and custom sections affects build time. |
| Integrations | Connecting stock, accounting, ERP or marketplace systems adds development and testing time. |
| Migration | Moving products, customers, orders and URLs from an existing store needs mapping and redirects. |
| Special functionality | Trade pricing, subscriptions, product builders or booking features may need extra apps, plugins or custom code. |

How long does it take?
Most of our ecommerce projects take 4 to 8 weeks from kickoff to launch. The biggest variable is usually how quickly product photos and descriptions are ready, so we plan content early.

06
Train & Support
A walkthrough of running the store, plus optional ongoing support.
Ecommerce SEO, Built In From Day One
An online store that isn't found doesn't sell, and fixing SEO after launch costs more than building it in. Every store we build includes:
- Product structured data (price, availability, reviews where genuine) so search engines understand each product
- Category pages with real introductory content, not just a grid of products
- Canonical tags so filters and sorting don't create thousands of duplicate URLs
- Google Merchant Center readiness for free product listings and Shopping ads
- Full redirect mapping when replacing an existing store (see website migration)

UK Rules Your Online Store Needs to Get Right
A few legal and practical requirements catch out new UK stores. We build them into the store rather than leaving them to you. This is general guidance, not legal advice.
- VAT-inclusive prices for consumers, with VAT set up correctly for your registration status
- Cancellation rights: under the Consumer Contracts Regulations most online purchases carry a 14-day cancellation period, which your terms and returns page should explain
- Cookie consent that meets UK GDPR and PECR before analytics or marketing cookies load
- Accessible design: readable contrast, keyboard-usable checkout and descriptive image text
Online Stores for Different Kinds of Business
Most of what makes a store work is specific to what it sells and who buys it.
Independent Retailers
Shops adding online sales alongside a physical store, where shared stock and click-and-collect matter as much as the website itself.
Trade & B2B Suppliers
Account-based pricing, bulk ordering, VAT-exclusive trade views and quote requests alongside a public catalogue.
Makers & Brands
Direct-to-consumer brands where storytelling, photography and made-to-order lead times need as much care as the checkout. See our work for furniture retailers and makers.

Ecommerce Web Design FAQs
With Webgenix, Shopify and WooCommerce stores start from £2,500 on a fixed-price quote. The final figure depends on how many products you sell, how many product variations you need, whether stock or accounting systems must be connected, and how much custom design is involved. You get a written quote before any work starts, so the price does not move halfway through.
Choose Shopify if you want a hosted platform where security, updates and checkout are managed for you and you are happy with a monthly subscription. Choose WooCommerce if you want to own the whole site on your own hosting, need unusual product or pricing rules, or already run a content-heavy WordPress site. We build on both, so the recommendation follows your requirements rather than our preference.
Most of our ecommerce projects take 4 to 8 weeks from kickoff to launch. A focused store with a small catalogue sits at the shorter end; large catalogues, product imports from an old system and third-party integrations push it towards the longer end. The biggest single factor is usually how quickly product content and photography are ready.
Yes, provided the migration is planned properly. We map every old product, category and page URL to its new address, set up 301 redirects, carry over titles and descriptions, and check Search Console after launch. Rankings can fluctuate for a few weeks after any migration, but a mapped migration avoids the permanent losses that come from broken links and missing pages.
Yes. On WooCommerce you own the code, the database and the hosting account outright. On Shopify you own your store content, products, customer data and theme, while the platform itself is rented through your Shopify subscription. In both cases the accounts are set up in your name, not ours.
Usually, yes. Both Shopify and WooCommerce connect to common UK accounting tools such as Xero and QuickBooks, and to many stock, shipping and marketplace systems, either through established apps and plugins or through a custom API integration. We check what your current systems support during discovery and include any integration work in the fixed quote.
