Who We Help

Build and Rebuild

Launching a new brand on Shopify, or rebuilding a store that no longer reflects where your business is today? We design and develop Shopify stores from discovery through to launch, combining strong eCommerce design with performance-focused development.

Migrate to Shopify

Moving from WooCommerce, Magento, BigCommerce or a custom platform? We manage the full migration: data transfer, SEO preservation, redirect mapping and rebuilding your store on Shopify without losing the visibility you have already earned.

Ongoing Development

Already on Shopify but need a development partner you can rely on? Our development retainer covers CRO testing, performance improvements and new functionality as your store evolves.

A Shopify development agency you can trust

You deserve a development team that understands eCommerce, not just code. Our team has been building Shopify stores since 2017, working with brands across fashion, lifestyle, toys and golf retail to create online experiences that genuinely perform.

Whether you need a brand-new Shopify store built from the ground-up, a fresh set of eyes on an underperforming site, or a full migration away from another platform that’s holding you back. We’ve done it again, and again.

Whether we’re developing Shopify stores from scratch for brands like Clarkes’ Golf or providing a much-needed facelift for existing brands like Charles & Ivy, we can do it all to give you a store that fits your business, not just a template that could fit everyone else.

How We Deliver Shopify Projects

Every Shopify project follows a clear process designed to reduce risk, keep momentum and make sure the store is ready to perform from launch.

1. Discovery

We start by understanding your business, customers, catalogue, integrations and workflows, so the solution is shaped around how you actually operate.

2. UX and UI Design

We map the full store experience before development begins, combining customer journey thinking with high-fidelity designs so you can see exactly how the store will look and work.

3. Development

We build custom Shopify stores with performance, flexibility and long-term maintainability in mind. For more complex projects, this can include integrations, middleware, subscriptions, configurators and custom multi-supplier fulfilment logic.

4. QA and Client UAT

Before launch, every store goes through internal QA. By the time it reaches client UAT, it should feel complete, making sign-off a review stage rather than a bug hunt.

5. Launch and Ongoing Development

We support go-live with final checks, launch support and a 30-day warranty period. After launch, many clients continue with us through a Shopify development retainer covering CRO, performance, new features and ongoing optimisation.

What Our Customers Say

If we’re being honest, we didn’t expect to see results for six months, but they started coming within the first few weeks. Registrations are now double or triple what they were this time last year. Paramount’s team took the time to understand our niche business model and was incredibly self-sufficient from the start. Communication is …

Inkthreadable

We’ve never felt like an afterthought. Communication is clear, the team is responsive, and they’ve taken the time to really understand our challenges. It feels like a very personalised service.

Charlotte Rottenburg

OneWelbeck

Paramount have been doing our SEO for several years now and they have done excellent work for us. We have recently commissioned them to do our new website and we are very happy with the results of that too. The team are accessible and friendly and work together to help with any of our challenges.

Dave Allan

Doxbond Cambridge

Paramount understood who our market is, who we need to influence, and how to communicate with them. The tone of voice and professionalism were spot-on. I’ve worked with many agencies, and I’ve had no misgivings about working with Paramount, quite the opposite.

Jonathan Hooper, Marketing Manager

ALLpaQ

I have been working with the developers at Paramount (as part of my employment at Socitm) for a few years now, and I am immensely impressed. We have established a great rapport pretty much straight away, with project management tools and great communication. The developers I work with are easy to talk to, understand our …

    Frequently asked questions ❓

    The answers to
    your Shopify Development questions

    What platforms can you migrate to Shopify from?

    We regularly migrate eCommerce stores to Shopify from platforms such as WooCommerce, Magento, BigCommerce and custom-built systems. Each migration is different, but typically involves transferring product data, customers, order history and content while rebuilding the storefront on Shopify’s architecture.

    Rather than simply copying everything across, we often take the opportunity to clean and restructure product data so it works more efficiently within Shopify. This helps ensure the new store is easier to manage and better prepared for future growth.

    Will we lose our SEO rankings when migrating to Shopify?

    A platform migration can affect SEO if it is not planned properly. The most common issue is changes to URL structures, which can cause search rankings to drop if redirects are not handled correctly.

    When migrating stores to Shopify we work closely with our SEO team to map redirects, transfer key metadata and ensure the new store launches with a clean search-friendly structure. While no agency can guarantee rankings, careful planning significantly reduces the risk of losing existing visibility.

    Can Shopify integrate with our warehouse or ERP system?

    Yes. Shopify can integrate with a wide range of systems including warehouse management systems (WMS), product information management platforms (PIM) and enterprise resource planning software (ERP).

    Our team regularly supports projects where Shopify needs to exchange product data, inventory levels and order information with other business systems. These integrations may be handled through middleware platforms or custom integration layers depending on the complexity of the system architecture.

    Do you support Shopify POS for retail stores?

    Yes. Shopify Point of Sale allows businesses to manage online and in-store sales through a single platform.

    We support brands implementing Shopify POS across retail locations, pop-up stores and event-based retail. This ensures inventory, customer data and reporting remain aligned between online and physical sales channels, giving merchants a single view of their operations.

    What does a Shopify development retainer include?

    A Shopify development retainer provides ongoing access to the same developers who built your store. Rather than treating development as occasional projects, retainers allow us to work continuously on improving and evolving the store.

    Typical retainer work includes CRO experiments, performance improvements, new features, product page enhancements, app audits and replacing unnecessary apps with more efficient custom functionality. Each month we work collaboratively with clients to prioritise the changes that will have the biggest commercial impact.

    Do you build custom Shopify themes?

    Yes. Many of the stores we build use custom Shopify themes developed specifically for the brand and customer experience.

    Depending on the project requirements, we may either develop a theme from the ground up or heavily customise a Shopify theme to meet the brand’s needs. Our goal is always to ensure the storefront reflects the brand properly while maintaining strong performance and long-term maintainability.

    How long does a Shopify development project take?

    The timeline for a Shopify build depends on the size and complexity of the project. Smaller builds may take a few weeks, while larger projects involving migrations, integrations or complex catalogue structures can take several months.

    During the discovery phase we work with clients to define the scope, priorities and delivery timeline so expectations are clear from the beginning. This ensures the project progresses in a structured and predictable way.

    Do you work with existing Shopify stores or only new builds?

    Many of our clients already have a Shopify store when they begin working with us.

    In these cases we typically start with a technical and performance review of the existing store before recommending improvements. This may involve refining theme architecture, improving Core Web Vitals, restructuring product catalogues or replacing inefficient apps with more scalable solutions.

    For many brands, working with an experienced Shopify development team can unlock significant improvements without needing to rebuild the entire store.

    Do you work with Shopify Plus stores?

    Yes. The team has delivered Shopify Plus projects across fashion and apparel, health and beauty, sports, and home and interiors. That work has included high-volume stores, complex third-party integrations, multi-market and multi-currency setups, and advanced catalogue architectures.
