As an accredited Shopify agency, we help brands launch and scale Shopify and Shopify Plus stores. We pair creative, on-brand ecommerce design with expert Shopify development - building bespoke themes from scratch or expertly adapting pre-built themes - and align every project with your brand strategy and our search-first foundations.
Our in-house designers and developers deliver complex ecommerce builds with clean code, fast load times and scalable architecture. We work with brands across fashion, beauty, food & drink, lifestyle, sport and B2B, with a strong focus on clear communication, quality delivery and long-term reliability - so every project launches on time, on budget and ready to scale.

Launching your store is only the beginning. Our monthly Shopify retainers keep your store improving long after go-live. HelpDesk covers day-to-day Shopify support, maintenance and smaller design & development tasks, while SiteLab drives strategic on-site growth through behavioral insight, A/B testing and continuous experimentation.
SiteLab retainers combine conversion rate optimization, performance analysis and search-first thinking to improve visibility, usability and revenue - with HelpDesk support included as standard. You get direct monthly access to our Shopify designers, developers and strategists, so your store keeps evolving with clarity, intent and measurable impact.
CleanCo
Our specialist Shopify SEO and GEO (generative engine optimization) team knows the nuances of Shopify and Shopify Plus inside out. We take a fast-moving, holistic and data-led approach that blends technical SEO, keyword-led content marketing and digital PR to deliver commercially driven results.
Using industry-leading SEO tools and in-depth competitor analysis, we build targeted campaigns that grow your visibility across Google, Bing and AI-driven search experiences such as ChatGPT, Gemini and Google AI Overviews - while continually uncovering new ranking opportunities and keeping user experience at the heart of every decision.
RNLI
Writing high-quality code is matched only by our deep understanding of the Shopify platform. Our developers are experts in Liquid, HTML, CSS, JavaScript and modern frameworks, and we build stores optimized for speed, Core Web Vitals, technical SEO and accessibility - whether we're creating themes and functionality from scratch or extending an existing template.
We build on Shopify's Online Store 2.0 architecture so your marketing and brand teams can update content without a developer. We also have extensive experience integrating trusted Shopify app partners and complex third-party systems as your business scales, all backed by rigorous quality assurance on every release.
Harbour Lifestyle
Our creative UX and UI designers craft distinctive ecommerce experiences that help your store stand out in fast-moving markets. Every project starts with a competitor, customer and data discovery audit, followed by wireframes that map page layouts for maximum engagement - before we move into high-fidelity design.
We bring your brand identity, imagery and tone of voice to life while carefully designing the journey to purchase: fewer clicks to checkout, smarter product discovery, upsells and cross-sells, and meticulous attention to detail. The result is beautiful, on-brand and commercially driven Shopify web design that makes the most of the platform.

We've migrated D2C and B2B brands to Shopify and Shopify Plus so they can unlock the commercial benefits of one of the world's leading commerce platforms. Trusted by millions of merchants and many of the world's fastest-growing brands, Shopify offers a low total cost of ownership, with hosting, security, checkout, order and inventory management, multi-currency selling and much more built in.
Thousands of approved apps extend Shopify's functionality, and native integrations make it easy to connect your marketing channels - a key reason so many businesses migrate from Magento, WooCommerce, BigCommerce and Salesforce Commerce Cloud. Our proven Shopify migration process protects your data, URLs and SEO rankings for a seamless switch.
Billionaire Boys Club

Creative, Technical & Strategic
A people-first team of creative, technical and strategic ecommerce experts, guiding brands through transformative growth journeys.
Our Story 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.
OneNext Solutions is a full-service Shopify agency. We offer Shopify and Shopify Plus web design, custom theme development, Shopify migrations, app development and integrations, Shopify SEO and GEO, conversion rate optimization (CRO), Klaviyo email and SMS marketing, international expansion, and ongoing support and maintenance retainers. Whether you are launching a new store or scaling an established brand, we cover the full ecommerce lifecycle.
Because we focus only on Shopify, our designers, developers and strategists know the platform inside out - its themes, apps, checkout, Shopify Markets and Shopify Plus features. That specialism means faster delivery, fewer technical surprises, better performance and SEO, and advice that is grounded in what genuinely works for Shopify merchants.
Yes. Our design and development services are dedicated to Shopify and Shopify Plus; we do not build on WooCommerce, Magento, BigCommerce or custom platforms. If you are currently on another platform, we can migrate your store, products, customers, orders and SEO to Shopify.
Timelines depend on the scope of the project, the features you need and the size of your catalog. A theme-based store can launch in a few weeks, while a bespoke Shopify or Shopify Plus build with custom integrations typically takes a few months. After an initial consultation we agree a clear timeline with milestones for discovery, design, development, testing and launch.
Yes. Every Shopify migration includes an SEO migration plan: we map and redirect URLs, preserve metadata and structured data, migrate content and products, and monitor rankings and traffic after launch to protect - and grow - your organic visibility.
Absolutely. Whether your store needs a complete redesign or targeted improvements, we start by auditing your current site, analytics, customer feedback and competitors. We then design a faster, more modern and conversion-focused experience that reflects your brand and makes it easier for customers to buy.
Shopify provides enterprise-grade security as standard, including SSL certificates, PCI DSS compliant checkout and payment processing, and continuous platform monitoring. We add to this with secure development practices, careful app selection, user-permission reviews and regular updates as part of our support retainers.
Yes. Our HelpDesk retainers cover day-to-day Shopify support, bug fixes, updates and smaller design and development tasks, while our SiteLab growth retainers add CRO, A/B testing and performance optimization. Our team responds promptly so your store keeps running smoothly and keeps improving.
Certainly. We integrate Shopify with ERPs, CRMs, inventory and fulfillment systems, analytics tools, reviews, loyalty, subscriptions and marketing platforms such as Klaviyo. We recommend the right tools for your business and build custom integrations where off-the-shelf apps fall short.
Simply contact our team and tell us about your goals. We will arrange an initial consultation to understand your business, then send a detailed proposal covering scope, timeline and investment. Once approved, we kick off your project and keep you informed and involved at every stage.
