Ecommerce Development
Custom storefronts, product systems, payment integrations, and performance optimisation.
01Overview
We build commerce experiences that are fast, reliable, and tailored to how the business actually sells — not constrained by a generic platform. Product, checkout, and inventory logic are engineered for conversion and stability.
02How we approach it
Commerce projects start with the selling, not the software. During Discover we map how orders actually move through the business: catalogue structure, pricing rules, stock, fulfilment, and the payment and back-office systems already in place. Define turns that into an architecture — what the new platform owns, what it integrates with, and how checkout, product, and inventory logic fit together. Non-standard requirements surface here, on paper, where they are cheap to resolve.
Design works from the real catalogue, not placeholder products. Product pages, navigation, and checkout are laid out around how customers browse and buy — and around the awkward realities of the range: long titles, missing images, variable option counts. The interface system is specified so engineering can build it without guesswork, and the paths that earn revenue — search to product to payment — get the most design attention.
Engineering treats the storefront as a system under load. Frontends are server-rendered and held to Core Web Vitals budgets, because speed on product and checkout pages is a commercial matter. Payment, inventory, and integration logic sit behind typed contracts with schema validation at every boundary. Validate then works through the edge cases a live shop will meet — stock changing mid-checkout, failed payments, retried webhooks — before a customer ever does.
Launch is staged so trading never stops. The new storefront moves through controlled environments, with data migration rehearsed and payment flows tested end to end before the switch. After Deploy, the work shifts to Evolve: monitoring what customers do, watching performance against budget, and improving the catalogue, checkout, and integrations in controlled increments rather than risky rewrites.

07Common questions
What determines the cost of an ecommerce build?
The main drivers are catalogue complexity, how far checkout departs from a standard flow, the number of systems the storefront must integrate with — payments, stock, fulfilment, accounting — and whether data is migrating from an existing platform. We publish no prices. After you send a brief through the contact form, we set out scope, deliverables, and cost in a written proposal, so the figure you agree to is tied to a defined build.
We currently sell through a hosted platform. How does migration work?
Carefully, and in stages. Product, customer, and order data are mapped and migrated in rehearsed runs, with a redirect plan protecting existing search rankings. Your current shop keeps trading while the new storefront is built and tested in controlled environments; the cutover happens only once payment flows and data have been verified. Whatever the old platform does well is treated as a requirement, not lost in the move.
Can the storefront connect to our stock, fulfilment, and accounting systems?
Yes — that connection is usually the reason a custom build is worth it. During Discover we audit each system's interface and data quality, then design an integration layer with typed contracts and schema validation, so bad data is caught at the boundary rather than reaching a customer. Failure modes are handled deliberately: if a downstream system is unavailable, the storefront degrades in a defined way instead of failing an order.
What happens after the storefront launches?
That is agreed before launch rather than assumed. Every project ends with a documented handover; deliverables, ownership, and any ongoing service commitments are defined in the written engagement agreement each project signs. If you want continuing support, our technical maintenance service covers monitoring, security and dependency updates, and controlled improvements — the Evolve stage of the process. If your own team is taking over, the handover is structured for that instead.
How do you measure whether the new storefront is working?
Against measures agreed in Define, not impressions. Typical ones are conversion through the checkout path, page speed against Core Web Vitals budgets, order error rates, and the operational time integrations save. Where an existing shop is being replaced, we measure it before the rebuild, so improvement is verifiable rather than claimed. Monitoring runs from launch, and the same measurements drive what gets improved during Evolve.
