Expanding a Shopify store beyond a single market means more than translating a few product pages. It means local currencies, tax logic, shipping rules, language variants, and checkout flows that feel native to each region — all without breaking the store you already rely on for revenue. By Design UK builds Shopify internationalisation projects for growing UK brands, at fixed prices, with full source code ownership and no long-term lock-in.
We sit deliberately between hiring a freelancer and briefing a large agency. You get senior-level engineering, AI-accelerated build timelines, and a fixed quote before any work starts — not a day-rate estimate that grows as the project does.
A proper internationalisation build typically covers:
Each of these can be delivered as a standalone module or bundled into a full internationalisation rollout, depending on how many markets you’re targeting and how customised your current theme and app stack already are.
Shopify build and internationalisation projects with By Design UK typically range from £499 to £18,999, depending on scope — a single-market currency and language expansion sits at the lower end, while a full multi-region rollout with custom apps, integrations, and localised checkout logic sits higher. Every quote is fixed before work begins, so there’s no scope creep billed by the hour. For stores that need ongoing monitoring, updates, and priority fixes once live, we also offer Shopify support plans from £299/month.
If your internationalisation plans extend into building a dedicated customer portal, subscription platform, or B2B ordering system alongside your Shopify storefront, that typically shifts into custom software territory — our SaaS development tier covers builds from £18,000 up to £650,000+ for complex, multi-tenant platforms.
Freelancers are often cheaper upfront but carry real risk: availability gaps, inconsistent documentation, and no guarantee you’ll retain clean, transferable code if the relationship ends. Traditional agencies solve some of that but introduce their own problems — slow discovery phases, opaque day-rate pricing, and account layers between you and the people actually writing the code.
By Design UK is structured differently. You get a fixed price agreed upfront, direct access to the engineers building your project, AI-accelerated development that compresses typical build timelines, and full ownership of the source code once the project is delivered. Nothing is retained, licensed back, or held hostage behind a support contract.
We don’t just build Shopify projects for clients — we build and operate our own software. Tackly.co.uk is a live multi-toolkit SaaS platform designed, built, and run by our team, and it’s a working example of the same engineering standards we apply to every Shopify internationalisation project: clean architecture, sensible integrations, and systems built to actually stay online. Combined with our UK base, fixed-price model, and full code ownership policy, it’s a level of transparency most agencies simply don’t offer. You can read more about how we work on our about page.
Most internationalisation projects start with a short scoping call to understand your current Shopify setup, target markets, and existing app stack. From there, we provide a fixed quote and a realistic delivery timeline before any development begins. Explore our full Shopify services or get in touch to discuss your expansion plans.
We work with existing stores in the majority of cases. Internationalisation is usually layered onto a live storefront, so we assess your current theme, apps, and integrations before recommending the most stable approach to expanding into new markets.
Yes. Full source code ownership is included as standard on every project we deliver, with no licensing fees or retained access requirements once the build is complete.
Timelines vary by scope, but our AI-accelerated development process typically delivers single-market expansions in a matter of weeks, with larger multi-region rollouts taking longer depending on integration complexity.
We offer ongoing Shopify support plans from £299/month covering monitoring, updates, and priority fixes, so your internationalised store stays stable as new markets and traffic scale up.
