A Shopify ecommerce agency focused on growth.

NORVA Systems is a UK-based Shopify agency specialising in high-performance ecommerce design and development. We work with brands that require more than off-the-shelf themes — building Shopify stores engineered for speed, clarity, and conversion.

From custom Shopify builds to store redesigns and ongoing optimisation, our work focuses on increasing revenue through better user experience, performance, and data-driven decisions.

We combine UX strategy, front-end engineering, and ecommerce best practices to create Shopify platforms that scale with traffic, products, and operations.

Strategy first.

We don't just build stores; we engineer sales systems. Every design decision is backed by conversion data and ecommerce psychology.

Performance-led.

Shopify speed matters. We use clean liquid code and modern front-end frameworks to ensure your store loads instantly on all devices.
