A Shopify Plus agency specialises in designing, building, and growing ecommerce stores on Shopify's enterprise platform. Unlike general web agencies, a Shopify Plus agency understands the platform's advanced features such as checkout extensibility, Shopify Flow automation, B2B wholesale channels, and multi-store expansion — and knows how to use them to drive measurable growth. At Imaginaire, that also means embedding ecommerce SEO and PPC into every build from the start.

Shopify is built for small to mid-sized stores. Shopify Plus is its enterprise tier, designed for brands processing high volumes of traffic and transactions. It unlocks checkout customisation, advanced automation through Shopify Flow, up to nine expansion stores, dedicated B2B functionality, unlimited staff accounts, and priority support. For brands hitting the ceiling on standard Shopify, Plus removes the constraints.

A custom Shopify Plus build typically starts from £40,000 and can scale significantly depending on complexity. Headless architecture, third-party integrations, multi-market setups, and bespoke functionality all influence the final scope. Every project at Imaginaire begins with a discovery phase to define requirements and budget before any commitment.

Headless Shopify separates the frontend experience from the Shopify backend. The storefront is built using a framework like Next.js, while Shopify handles products, checkout, and payments via its Storefront API.

This gives brands complete design freedom, faster page loads, and much more control over SEO factors such as URL structures and content hierarchy.

Yes. Most of our clients move onto a growth retainer after launch, covering ongoing development, conversion rate optimisation, SEO, and PPC. Ecommerce doesn't stop at launch — the brands that grow fastest treat their store as a living product, not a finished project.

We can also take on existing Shopify Plus projects in a lot of cases and then have our developers work with your existing codebase for general maintenance and new features.

Design, development, ecommerce SEO, and PPC all sit within one team. Most agencies either build stores or market them, rarely both. That means our developers understand search performance and our SEO strategists understand the technical constraints. It's a tighter feedback loop that produces stores built to rank, convert, and scale from day one.
