Most people who dream of running an online business aren’t looking for a second job. They’re looking for a second income — something that ticks along quietly in the background while they carry on with their actual job, their family, or the next idea on their list. The good news is that a properly built online store can genuinely run itself. Payments taken automatically. Orders and stock tracked without you touching a spreadsheet. Customer emails sent without you lifting a finger. That’s not a fantasy — it’s just good engineering.
This is exactly the kind of project we love at By Design UK. We’re a UK software development studio that sits between a freelancer and a traditional agency: fast and personal like a freelancer, but reliable, structured, and fully accountable like an agency — without the inflated day rates or the six-month timelines. Whether you’ve got a product idea sitting in a notebook, a side hustle you want to formalise, or you simply want a low-maintenance income stream alongside your main job, we build the store, wire up the automation, and hand you the keys.
“Hands-off” doesn’t mean you disappear entirely — it means the boring, repetitive parts run without you. A well-built store handles:
Once that foundation is in place, your day-to-day involvement can genuinely shrink to checking in occasionally rather than living inside the admin panel. That’s the difference between a side hustle that owns you and one that works for you.
We work in fixed-price tiers, agreed before we start, so there are no surprise invoices halfway through the build. Our Shopify build services range from £499–£18,999 depending on complexity — from a lean, single-product store designed for a first-time side hustle, right up to a fully custom, multi-product storefront with bespoke automation, integrations, and design. For business owners with bigger ambitions — think a platform-style product rather than a simple storefront — we also offer full SaaS development, ranging from £18,000 to £650,000+, for when “online store” grows into “online software business.”
Once your store is live, most owners want peace of mind rather than a second job in web maintenance. That’s what our support plans are for — starting from £299/month for Shopify stores (or £797/month for SaaS platforms), covering monitoring, updates, and quick fixes, so your hands-off business actually stays hands-off.
Freelancers are often cheaper upfront, but they can disappear mid-project, and you’re frequently left without proper documentation, clear ownership of the code, or anyone to call when something breaks. Traditional agencies solve the reliability problem but introduce new ones: slow timelines, opaque day-rate pricing that creeps upward, and layers of account managers between you and the person actually building your store. By Design UK sits deliberately in between — fixed prices agreed upfront, full ownership of your source code from day one, and a small, UK-based team that actually builds the thing you’re paying for.
As proof of what we can build and run at a technical level, take a look at Tackly.co.uk — a live, multi-toolkit SaaS platform we designed, built, and continue to operate ourselves. It’s a working example of the automation, reliability, and polish we bring to every project, whether it’s a simple Shopify store or a full software platform.
If you’ve got a product idea, a growing side hustle, or simply want an income stream that doesn’t demand your evenings, a properly automated store is one of the most realistic ways to get there. You don’t need technical skills, a big budget, or hours a day to spare — you need a well-built foundation and a clear plan for what happens after launch. That’s what we provide, from the first conversation through to ongoing support.

Yes, once payments, inventory, and order notifications are properly automated, most day-to-day tasks handle themselves. Owners typically check in periodically rather than managing everything manually, especially with a support plan monitoring things in the background.
Our fixed-price Shopify builds range from £499 to £18,999 depending on complexity, features, and the level of automation required. We agree the price upfront so there are no surprises during the build.
Yes. Full source code and store ownership transfers to you, unlike some agency or platform arrangements where you’re locked into ongoing dependency on the builder.
You can run it independently, or opt into one of our support plans, starting from £299/month for Shopify stores, which covers monitoring, updates, and minor fixes so the store keeps running smoothly with minimal input from you.
