If you’re an e-commerce store that’s ready to take your business to the next level, using Opium Works Digital as your Shopify Agency is the step you need to take. We combine strategy, UX design and technical expertise to deliver Shopify solutions that go beyond standard templates.

We work with brands on everything from new store launches to complex platform migrations, combining design, development and growth strategy in one team. 

What is a Shopify Agency?

A Shopify agency is a specialised ecommerce agency focused on building, optimising and growing online stores using the Shopify platform. Unlike general web agencies, a Shopify agency brings deep platform expertise, understanding the nuances of Shopify’s ecosystem, tools and integrations.

In practice, that means we know which apps cause performance issues, where the platform's native checkout creates friction, and when a headless build is genuinely worth the complexity  (and when it isn't). That kind of practical knowledge comes from doing it repeatedly, not from occasionally offering it as a service.

Our Core Shopify Services

We operate as a full-service Shopify agency, delivering end-to-end e-commerce solutions that go beyond simply building an online store. From initial strategy and UX design to development, migration and ongoing growth optimisation, we support brands at every stage of their Shopify journey.

We work with both standard Shopify stores and enterprise-level Shopify Plus builds, offering the flexibility to support businesses of all sizes. 

Our core Shopify services span the full e-commerce lifecycle, including store design and UX, custom development, platform migrations, SEO and growth marketing, as well as ongoing support and optimisation.

Shopify Store Design & UX

A successful Shopify store starts with strong, brand-led design that reflects your identity and helps you stand out in a competitive e-commerce landscape. As a Shopify design agency, we create visually distinctive stores that align with your brand while supporting performance and growth.

UI/UX strategy plays a critical role in guiding users through the buying journey; from first interaction on the homepage to a seamless checkout experience. We design with a mobile-first mindset, delivering responsive experiences across all devices that ensure clear navigation, intuitive product discovery and conversion-focused product pages that drive action.

Shopify Migrations

We support seamless migrations to Shopify from platforms such as WooCommerce, Magento, BigCommerce and Wix, ensuring a smooth transition without disruption to your business. Careful planning is essential to avoid downtime or lost sales, which is why our process is structured and thoroughly managed.

We handle every aspect of the migration, including product data and catalogue transfer, customer accounts and order history, URL redirects and SEO preservation, as well as integration with existing tools and apps.

Before launch, we conduct extensive testing and quality assurance to ensure everything functions correctly, delivering a secure, stable and fully optimised Shopify store from day one.

Shopify SEO & Growth Marketing

Building your Shopify store is only the first step. Ongoing growth strategies are essential to drive traffic, increase conversions and maximise revenue. As a Shopify digital agency, we combine technical SEO, content optimisation and paid marketing to help e-commerce brands scale effectively.

Our strategies are data-driven and tailored to each client’s audience, industry and growth objectives, ensuring every action contributes to measurable results.

Our growth approach includes:

  • Organic Search Optimisation: Keyword targeting, technical SEO and optimised product and collection pages
  • Paid Advertising & Conversion Funnels: PPC campaigns, social ads and retargeting strategies
  • Analytics & Performance Tracking: Monitoring user behaviour, traffic sources and sales data to refine performance

Ongoing Support & Maintenance

Our ongoing support services are designed to help businesses maintain, optimise and scale their Shopify store over time. As your store evolves, we ensure it continues to perform at its best through continuous monitoring and improvement.

This includes performance monitoring and updates, bug fixes and technical improvements, as well as the implementation of new features and enhancements to support growth.

Ongoing collaboration allows us to adapt your Shopify store as your business expands, ensuring it remains aligned with your goals. With a dedicated team of Shopify experts available, you gain continuous guidance, optimisation and support to drive long-term success.

Shopify Plus Expertise

For high-growth and enterprise e-commerce brands, Shopify Plus offers advanced capabilities designed to support scale, complexity and global expansion.

We build Shopify Plus stores with custom checkout flows using Checkout Extensibility, headless front-ends where the performance case is genuine, multi-market internationalisation and automation via Shopify Flow. We also handle the enterprise integrations that typically accompany a Plus build.

Our Shopify Process: From Strategy to Launch

We follow a structured, end-to-end process to ensure every Shopify store we build is aligned with your business goals and optimised for performance from day one.

Step 1: Discovery & Strategy: We start by understanding your brand, audience and commercial objectives. This phase defines the foundation of your Shopify store, ensuring every decision supports your growth strategy.

Step 2: Design & Wireframes: Our team develops UX/UI concepts and wireframes to map out the customer journey and create a seamless user experience. This includes visual direction, layout planning and interaction design.

Step 3: Development & QA: We build your Shopify store through iterative development, implementing custom functionality, integrations and performance optimisation. Rigorous testing ensures everything works flawlessly across devices and browsers.

Step 4: Pre-launch Optimisation: Before launch, we optimise your store for search engines and performance, including technical SEO setup, speed optimisation and final quality checks.

Step 5: Launch & Measure: Launch is managed in a structured window, with real-time monitoring for the first 48 hours. We check indexing, confirm checkout flows, validate tracking and watch for any errors that only appear under live traffic. From there, we move into monthly review cycles with a clear agenda rather than a vague "ongoing optimisation" promise.

Frequently Asked Questions (FAQs)

Do I need Shopify Plus or regular Shopify?

Shopify Plus is the enterprise-grade version of Shopify, designed for high-growth and large-scale businesses that require advanced functionality, scalability and flexibility. It enables brands to manage complex operations, multiple storefronts and international markets through a single platform, making it ideal for an enterprise Shopify store.

Regular Shopify, on the other hand, is well-suited for small to medium-sized businesses looking to launch and manage an online store efficiently.

Can you migrate my store from another platform?

Yes. We've handled migrations from WooCommerce, Magento, BigCommerce, Wix and custom-built platforms.

We do full redirect mapping, maintain URL structures where possible and treat your current rankings as something to protect, not risk. Everything runs in a parallel environment until it's been fully validated. We won't push you live until we're confident nothing will break.

Will my Shopify store be SEO-friendly?

Yes. Shopify is an SEO-friendly e-commerce platform when built and configured correctly. As a specialist agency, we implement SEO best practices from the very beginning.

From a technical perspective, we ensure optimised site structure and navigation, clean URL structures, fast loading speeds aligned with Core Web Vitals, and mobile-first responsive design.

On-page SEO is also built into the foundation, including optimised product and category page templates, structured heading hierarchies, and guidance on meta titles and descriptions. Internal linking is carefully planned to support both user experience and search visibility.
Shopify also offers strong content opportunities, including blogs, collection pages and landing pages to target relevant keywords and capture search demand.

Beyond launch, we support ongoing SEO and growth optimisation through keyword strategy, content development and technical audits, ensuring your store continues to grow in visibility, traffic and revenue.
