Launching a Shopify store in the UK should be straightforward: a clear price, a working store, and code you actually own at the end of it. In practice, most businesses end up choosing between an unpredictable freelancer or a slow, expensive agency with opaque pricing. By Design UK sits between the two — a UK-based team that builds Shopify stores at fixed prices, uses AI-accelerated development to move faster without cutting corners, and hands over full source code ownership when the project is complete.
We don’t just talk about technical capability — we run our own live software. Tackly.co.uk is a multi-toolkit SaaS platform we built and operate ourselves, and it’s the clearest proof that we understand production-grade ecommerce and web architecture, not just theme customisation. If we can build and maintain a live SaaS product, we can build a Shopify store that’s fast, reliable, and set up to scale.
Our Shopify build services are priced from £499 to £18,999, depending on complexity. A simple store setup with a premium theme, product catalogue, and payment/shipping configuration sits at the lower end. Custom app integrations, bespoke theme development, multi-currency or wholesale functionality, and third-party system connections (ERP, CRM, fulfilment) push projects toward the higher end. Every quote is fixed before work begins — no hourly billing, no scope creep, no surprise invoices.
If your ambitions go beyond a storefront — for example a custom SaaS product, marketplace, or internal platform alongside your Shopify presence — our SaaS development service covers builds from £18,000 up to £650,000+ for enterprise-scale platforms, using the same fixed-price, full-ownership approach.
Freelancers can be affordable, but reliability, availability, and code ownership are often unclear until something goes wrong — a missed handover, an unresponsive contractor, or code that quietly remains someone else’s intellectual property. Traditional agencies solve some of that, but typically at the cost of speed and price transparency: long discovery phases, vague estimates that grow into large invoices, and layers of account management between you and the developers actually writing your store.
By Design UK is structured to avoid both problems. You get a named UK team, a fixed price agreed upfront, AI-accelerated build timelines that compress weeks of manual work into days without sacrificing quality, and complete ownership of the resulting codebase — no licensing dependency on us once the project ships. It’s the reliability of an agency with the speed and price certainty of working directly with the people building your store.
A typical engagement covers store architecture, theme selection or custom development, product and collection setup, payment and shipping configuration, essential app integrations, on-page SEO structure, and a pre-launch technical review covering site speed, mobile responsiveness, and checkout reliability. We also advise on which apps are genuinely necessary versus which add bloat and slow down page load — a common issue we see when auditing existing Shopify stores built elsewhere.
Once your store is live, ongoing performance, security updates, and feature additions matter just as much as the initial build. Our support plans start from £299/month for Shopify stores (SaaS support plans start from £797/month), covering monitoring, updates, minor enhancements, and priority response times — so your store doesn’t stagnate the moment it launches.
If you’re ready to discuss a UK Shopify store setup, get in touch via our contact page with a brief outline of your products and requirements, and we’ll come back with a fixed-price proposal. You can also read more about our approach, team, and the Tackly platform on our about page before you decide.
A standard store setup typically takes between one and four weeks depending on scope, with AI-accelerated development helping us compress build time without reducing quality checks. Larger custom builds with bespoke app integrations can take longer, and we’ll give you a realistic timeline as part of your fixed-price quote.
Yes. Full source code and store ownership transfers to you on completion. Unlike some freelance or agency arrangements, there’s no ongoing dependency on By Design UK to access, edit, or migrate your store.
Yes, we handle migrations from other platforms, including product data, customer records where possible, redirects to preserve SEO rankings, and theme rebuilds to match or improve on your existing design.
Most clients move onto one of our support plans, starting from £299/month, which covers updates, monitoring, small feature requests, and priority support so the store keeps performing as your business grows.
