Ecommerce Websites Built to Sell, Scale & Rank
Conversion-focused online stores on Shopify, WooCommerce, BigCommerce, PrestaShop and OpenCart — fast, mobile-first, SEO-ready, and prepared for the AI shopping agents that are already changing how people buy.
The short answer on platforms
We're platform-agnostic — we build on all five and recommend the one that fits your catalogue, budget and growth plans. Find yourself below.
The quickest route from idea to live store. Hosting, security and checkout are handled for you; we handle everything shoppers see.
The most widely used e-commerce system on the web — W3Techs puts it at 49% of sites with an identifiable store platform. You own everything.
Strong built-in SEO, multi-storefront, headless and B2B capabilities without app-stacking. The platform you grow into, not out of.
Free, open-source cores with multi-store and multi-currency support. Ideal when the budget is lean but the requirements aren't.
Not sure which fits? That's the first thing we settle in a free consultation — no upselling, just the right foundation. Already have a store that underperforms? Start with e-commerce UX optimization or a website redesign instead of a rebuild.
What changed for online stores in 2026
Four shifts now decide whether a new store sells — and none of them are solved by picking a pretty theme.
AI agents are becoming a sales channel
Shopping is moving into AI assistants. OpenAI and Stripe launched the Agentic Commerce Protocol (ACP) in September 2025 so agents can complete purchases inside chat. In January 2026 Google launched the Universal Commerce Protocol (UCP) as an open standard spanning discovery to post-purchase — and by April 2026 Amazon, Meta, Microsoft, Salesforce and Stripe had joined its Tech Council alongside Google, Shopify, Etsy, Target and Wayfair.
What this means for your build: a store whose product data AI agents can't read is invisible to a growing slice of buyers. We ship structured, machine-readable product feeds and schema from day one, and prepare stores for agentic checkout standards as platforms roll them out.
This pairs with answer-engine visibility — being recommended when shoppers ask ChatGPT, Gemini or Perplexity what to buy. That's the AEO/GEO work we run through our AI SEO services.
Speed is now a ranking and conversion input, not a nice-to-have
Google's Core Web Vitals set concrete targets — largest contentful paint within 2.5 seconds, interaction latency under 200ms, minimal layout shift — and measures them on real user devices, not lab machines. Theme bloat, oversized images and app-stacking are the usual culprits on store builds.
Every store we ship is built and tested against these thresholds on mid-range mobile hardware, because that's what your customers actually hold.
Checkout design decides more revenue than traffic does
Across 50 published studies, the average cart abandonment rate is 70.22% (Baymard Institute). The fixable causes are design decisions: costs revealed too late, forced account creation, long forms, missing trust signals. Baymard's testing shows better checkout design alone carries an average 35.26% conversion upside for large stores.
We design cart and checkout first, not last — and if you're diagnosing an existing store, that's exactly what our UX optimization service measures.
Stores that launch without a marketing foundation sit idle
A store nobody finds sells nothing. Because we run SEO, PPC, content and paid social in-house, your store launches with clean information architecture, indexable category structure, analytics and conversion tracking already wired — a foundation ready to grow, not a design that waits for traffic.

Shopify Design & Development
A custom-designed storefront on the world's best-known hosted platform — without the template look.
Shopify handles hosting, security and PCI compliance; we handle everything that decides whether visitors buy — theme customisation or fully custom design, conversion-focused product and checkout flows, app selection that doesn't slow the site down, and migration from your existing platform without losing SEO equity.
Where it's strong
Speed to market, reliability, and an ecosystem that covers almost any requirement. As a UCP Tech Council founding member, Shopify is positioned well for agentic commerce. Best default for D2C brands and first stores.
Where it falls short
Subscription plus app fees compound as you grow, checkout customisation is limited on standard plans, and you're building on rented land — leaving Shopify later means a real migration project.
Best for: brands that value launch speed and low maintenance over deep customisation and ownership.
WooCommerce Design & Development
Open-source e-commerce on WordPress — the web's most widely used store platform, and the one you fully own.
W3Techs measures WooCommerce at 49% of websites with an identifiable e-commerce system; store-count trackers put its share around a third of live stores. Either way, it's the dominant open-source choice — and because it runs on WordPress, it inherits the content and SEO capabilities that make organic growth compound. Our WordPress design team builds both sides.
Where it's strong
Total ownership of code and data, unmatched SEO flexibility, content marketing on the same install, and no per-transaction platform fees. If your growth plan is search-led, this is usually the recommendation.
Where it falls short
You carry the maintenance: hosting, updates, security and backups are your responsibility (or ours, under a care plan). Badly chosen plugins are the classic way Woo stores get slow — discipline matters.
Best for: businesses that want full control, plan to win through SEO and content, and expect to customise deeply. See our WooCommerce vs Wix comparison if you're weighing simpler builders.
BigCommerce Design & Development
A hosted platform with enterprise features on standard plans — multi-storefront, headless, and serious built-in SEO.
BigCommerce packs more natively into the platform — B2B price lists, customer groups, multi-storefront, headless APIs — where competitors lean on app stacks. That means fewer moving parts to slow the site and fewer monthly app fees compounding in the background.
Where it's strong
Scaling without re-platforming: strong native SEO controls, omnichannel selling, and B2B capability that would need a stack of paid apps elsewhere. No platform transaction fees on standard plans.
Where it falls short
A smaller theme and app ecosystem than Shopify, and a steeper learning curve for store admins. For a five-product first store, it's usually more platform than you need.
Best for: fast-growing catalogues, wholesale/B2B sellers, and merchants who want enterprise features without enterprise licensing.
PrestaShop & OpenCart Development
Free, open-source cores with native multi-store and multi-currency — for lean budgets with real requirements.
PrestaShop is a leading open-source platform in Europe and Latin America, with deep customisation and strong multi-store, multi-currency support for merchants selling across borders. OpenCart is the lighter option — quick to set up, easy to run, with thousands of extensions and themes. Both put the licence cost at zero and shift the investment into design, development and hosting, where it actually differentiates your store.
Where they're strong
No subscription fees, full code ownership, native multi-store/multi-currency, and freedom to customise anything. Well suited to region-specific requirements a SaaS platform doesn't prioritise.
Where they fall short
Smaller ecosystems and communities than Shopify or Woo, self-managed security and updates, and fewer developers who know them well — which makes partner choice matter more, not less.
Best for: cost-conscious SMBs with multi-currency or multi-store needs, and merchants who want open-source control without WordPress.
Built into every store we ship
Whatever the platform, these aren't add-ons — they're the baseline.
| Area | What you get |
|---|---|
| Speed | Built and tested against Core Web Vitals targets (LCP ≤2.5s) on real mobile hardware; image, theme and app-weight discipline throughout. |
| Mobile-first design | Designed for the phone screen first — thumb-reachable actions, persistent add-to-cart, layouts that survive small viewports. |
| Checkout & payments | Streamlined checkout with wallet/express options, secure gateways configured for your regions, and abandonment-fighting flow design. |
| SEO, AEO & GEO | Clean indexable architecture, structured data and machine-readable product feeds — visible to Google, Bing and AI answer engines alike. |
| Agentic-commerce readiness | Product data structured for AI shopping agents, with a path to ACP/UCP-based agentic checkout as platforms roll out support. |
| Operations | Inventory, orders, taxes, shipping rules and coupons configured; staff trained before launch. |
| Editable design | Layouts, banners, colours and content you can change yourself — no developer needed for everyday updates. |
| Marketing wiring | Analytics, conversion tracking, email and CRM connected from day one, ready for marketing automation. |
| Security | SSL, hardening and platform-appropriate security practices that protect customers and brand. |
Concept to checkout, in order
No guesswork and no surprises — you always know what's happening and what comes next.
- Discovery (free). Products, audience, budget, growth plans. We recommend a platform and give you a clear, itemized quote — the recommendation isn't tied to what's easiest for us to build.
- Architecture. Category structure, URL strategy and data model agreed before design starts, because retrofitting information architecture after launch is the expensive way to do it.
- Design. Figma wireframes and mockups for homepage, category, product, cart and checkout — reviewed with you, revised, and signed off before a line of code.
- Development. Fast, secure, mobile-first build with payments, shipping, inventory and marketing integrations. You see staging builds throughout, not a reveal at the end.
- Pre-launch QA. Full purchase-path testing on real devices, speed verification against Core Web Vitals, SEO and analytics checks, redirect mapping if we're migrating.
- Launch & grow. Go-live, monitoring, and ongoing support — with optional UX optimization and marketing to keep sales climbing after the launch spike fades.
What we commit to — and what we won't claim
- Quotes are itemized and fixed-scope. We price after the discovery call, in writing, with no hidden fees. We don't publish generic price tables because a 30-product store and a 5,000-SKU B2B catalogue are different projects — and pretending otherwise is how surprise invoices happen.
- Platform recommendations are independent. We build on all five platforms, so we have no incentive to push one. If a simple builder genuinely fits you better, we'll say so.
- The statistics on this page are sourced, verified 29 July 2026, and linked below. Numbers we can't verify don't appear.
- We don't guarantee sales figures. No agency controls your market, pricing or product demand. What we control — speed, findability, purchase-path design — we build to published standards and measure against your analytics.
- Migrations protect your SEO equity. Redirect mapping, content parity and ranking monitoring are part of the migration scope, not an optional extra — losing rankings in a re-platform is avoidable, and we treat it that way.
Ecommerce website design FAQs
How much does an ecommerce website cost?
It depends on platform, catalogue size, custom features and integrations — a focused small-business store is a very different project from a large custom B2B build. We quote after a free discovery call, itemized and fixed-scope, with no hidden fees. Be cautious of published flat rates: they either hide exclusions or assume a template-only build.
Which platform is best — Shopify, WooCommerce or something else?
There's no single best, only the best fit. Shopify wins on launch speed and low maintenance; WooCommerce wins on ownership and SEO flexibility; BigCommerce suits scaling and B2B stores; PrestaShop and OpenCart are strong open-source options for lean budgets with multi-store or multi-currency needs. We assess your products, budget and goals, then recommend — the comparison table above is the honest summary.
How long does it take to build an ecommerce website?
A straightforward store can go live in a few weeks; larger or heavily customised builds take longer. After discovery we give you a stage-by-stage timeline — design, development, QA, launch — and you see staging builds throughout, so the timeline is visible rather than promised.
Will my store be mobile-friendly and SEO-ready?
Yes — both are baseline, not add-ons. Every build is responsive across devices, tested against Google's Core Web Vitals thresholds, and structured for search from the architecture up: clean URLs, indexable categories, structured data. That includes AI answer engines (AEO/GEO), not just Google and Bing.
Can you make my store ready for AI and agentic commerce?
Yes, and it's a core focus. We structure product data so AI assistants like ChatGPT, Gemini and Perplexity can read and recommend your catalogue, run AEO/GEO optimization through our AI SEO services, and prepare stores for the agentic checkout standards now consolidating — Google's Universal Commerce Protocol (backed since April 2026 by Amazon, Meta, Microsoft, Salesforce and Stripe) and the Stripe/OpenAI Agentic Commerce Protocol.
Can you redesign or migrate my existing store?
Yes. We handle redesigns and platform migrations, moving products, content and SEO value carefully — redirect mapping, content parity and post-launch ranking monitoring are part of the scope. If the store's structure is sound and only conversion is the problem, UX optimization is often the cheaper, faster answer than a rebuild.
Do you provide support after the store goes live?
Yes — maintenance, updates, security and optimization, plus the growth side: we can run your SEO, ads and content marketing so the store keeps growing after launch rather than sitting idle.
