DESIGN + DEVELOPMENT · SHOPIFY
Your storefront isn't just a shop window — it's carrying your revenue. We design and build custom Shopify and Shopify Plus stores that turn browsers into buyers, from the first wireframe to the final conversion tweak.
WHAT YOU GET
01
Every store starts with your customer and your commercial goals, then works back into layout, hierarchy and messaging. We sweat the details that move the needle — product-page structure, trust signals, speed to checkout — so your store reflects your brand and sells around the clock.
02
Fast, stable, maintainable Shopify and Online Store 2.0 themes, hand-built in Shopify Liquid for genuine custom theme development that holds up under real trading. Our developers work in clean HTML, CSS and JavaScript, so the custom functionality your business needs is built properly — no bloated apps, no fragile workarounds — on foundations you can grow on for years.
03
Shopify Plus opens up the enterprise end of the platform, and we build to make the most of it — checkout extensibility, automation with Shopify Flow, and the wider app and integration ecosystem — with responsive layouts that adapt smoothly across every screen size and Shopify’s rock-solid, high-converting checkout underneath. When you’re ready to sell internationally, we extend the same build to multiple languages and currencies.
04
Moving from WooCommerce, Magento, BigCommerce or a custom build? We migrate your products, content and customers carefully and protect your hard-won SEO, so you keep your rankings and revenue — and lose the headaches. We handle the technical detail too, from domain setup to 301 redirects, so nothing breaks on the way across.
05
We don’t hand over a store and disappear. Conversion thinking runs through everything we do, and we keep testing after launch — A/B testing design changes against real user engagement, tightening page speed, product discovery, checkout and mobile to reduce cart abandonment — so your store stays optimised and gets stronger over time, not staler. And we keep it discoverable with strong, ongoing on-page SEO.
06
Most of your customers shop on their phones, so we build mobile-first as standard and sweat Core Web Vitals because slow stores lose sales. Accessible by design, effortless on any device, and rewarded with better conversion and stronger rankings.
HOW WE DELIVER
01
Audit your store, traffic and revenue and agree the goals. We map the opportunity before we touch a pixel — deciding whether you need theme customisation, existing apps or a custom Shopify app to extend the Shopify admin and improve the features your customers use, and how your team needs to access store data across the wider Shopify ecosystem.
02
Wireframes and visual design grounded in your brand — a reusable component system, not just a set of pages. When needed, we also plan UI patterns that create a more consistent experience across custom tooling and storefront touchpoints.
03
Your theme build developed for performance, with SEO and conversion baked in from the first line of code. For custom app work, this can require backend development as well as JavaScript, and we use Shopify CLI as a standard way to build, preview, manage, and test the app.
04
Zero-downtime launch onto Shopify’s secure, PCI-compliant, SSL-certified platform, then ongoing CRO and technical care to compound your results after go-live.
WHAT OUR CLIENTS SAY
The team at Milk Bottle Labs do a fabulous job. Projects always run smoothly and to schedule, with minimal intervention from our side.
Oonagh O'Hagan
Owner, Meaghers Pharmacy Group
In 2025, we tasked Milk Bottle Labs to migrate OneSonic from WordPress to Shopify. It was possibly the best business decision we made in 2025. A stress-free migration. It is a wonderful team.
David Cawley
Owner, OneSonic
The guys at Milk Bottle really over-delivered. The service and quality of work was impeccable, and I only wish all the companies I engage with were as enjoyable to work with as the team at Milk Bottle.

QUESTIONS
It depends on scope — the number of templates and the custom functionality you need. We scope every project up front and give you a clear, fixed proposal before any work begins, so there are no surprises.
Yes. We build on both standard Shopify and Shopify Plus, and we’ll advise which plan actually fits your business — sizing the build around your volume, your team and where you’re heading, so you’re on the right platform without paying for tiers you don’t need.
Absolutely. Replatforming is core to what we do. We migrate products, content and customers, map every URL with 301 redirects and protect your SEO, so you keep your rankings, traffic and revenue through the move.
Yes. We design and build mobile-first and tune for Core Web Vitals as standard, because speed and mobile experience directly affect both conversion and search rankings.
We can. Many clients move onto monthly performance management for ongoing conversion optimisation, merchandising and technical care. Design, development, email and SEO all sit under one roof, so the same team keeps growing your store.
