E-Commerce Development
in London

Storefronts that convert and checkouts that don't break at scale.

We build e-commerce storefronts for founders in London — headless Shopify Hydrogen when you need custom UX, a hardened Shopify Plus theme when speed matters more, custom carts when the platform gets in the way. One senior engineer owns checkout, inventory sync, and the storefront, so launch day isn't held together by three unrelated apps.

How this works

One AI-native engineer.
The output of a team.

One senior engineer plus AI agents now ships e-commerce development that used to need a four-person team. Same code quality, half the cost, three-week timelines instead of three months. Built for pre-seed to Series A founders in London who need to ship before the next round closes.

The local read

Why e-commerce development is hard in London

London founders have access to deep fintech and gov-tech talent but the hiring cycle is brutal. Senior offers in the City clear £100K base plus equity that competes with Revolut and Wise. Local dev shops mostly serve enterprise — slow procurement, multi-quarter contracts, agency-of-record billing.

Different model: one senior engineer ships your build in two weeks, four-to-five-hour overlap with our working hours, billed in USD. Open Banking via TrueLayer or GoCardless for fintech. Next.js + NestJS + Postgres for SaaS. Flat-price quote in 24 hours. Code in your GitHub from commit one.

London's accelerator bench includes Seedcamp (since 2007, early backer of Revolut, Wise and UiPath), Techstars London and Entrepreneur First, which matches and funds co-founders before they've even formed a company. Early checks come from Passion Capital (Monzo, GoCardless, Tide) and Stride VC, which raised a $138.6M second fund. The fintech concentration is the real story: London is home to 2,500+ fintech companies and captured 79-90% of all UK fintech funding in 2025 out of roughly £2.6B invested nationally. That density comes at a cost for founders — the median advertised software engineer salary in London sits at £115K, and the UK's 2025 immigration reform raised the Skilled Worker visa threshold to degree-level roles with a £41,700 salary floor, tightening the pipeline further. 95% of UK engineering employers now report talent shortages.

London's AI funding hit a record in 2025: London-based AI companies raised £5.73B across 682 rounds, inside a UK-wide £8.3B AI investment total — roughly three times what was raised in 2024. The office real estate is following the capital: OpenAI announced its first permanent London office in April 2026, an 88,500-sq-ft space at King's Cross opening in 2027 with room for 544 staff, more than double its current London headcount, while Google's million-square-foot King's Cross tower is built for up to 7,000 people. On the funding side, LocalGlobe, deploying 80% of its capital in the UK since 1999, has backed 17 unicorns and 5 IPOs, and Balderton Capital raised $1.3B combined across two funds in 2025 alone. That's an enormous amount of capital and corporate gravity landing in a few square miles — and every one of those companies is hiring against the same senior engineer you need.

Most of the e-commerce development briefs we get out of London trace back to its Fintech and AI base — that's the local demand, not a guess.

Hiring one senior engineer here is a ~$200K year-one outlay and a 60–90 day search. Our e-commerce development engagement starts at $3,000 with a first deploy in 2–3 weeks.

FAQ

Common questions about e-commerce development in London

How fast can you start?

+
Most builds begin within seven days of the first call. We don't sell discovery — we go from problem statement to first deploy on the same day-one timeline.

Is the price really flat?

+
Yes. After a 30-minute call we send a single number and a scope you can accept or reject. No hourly billing, no change-order games. If we underestimate, we eat it.

Headless Hydrogen or a Shopify Plus theme?

+
Theme-based if you need to launch in two weeks and the design is close to what Shopify templates support well. Headless Hydrogen if you need custom UX, sub-second page loads, or you're integrating commerce into a larger product rather than shipping a standalone storefront.

Do you migrate from another platform?

+
Yes — most commonly from WooCommerce or a custom cart to Shopify. Product catalog, customer accounts, and order history migrate; we flag anything that won't map cleanly before we start.

Who owns the code?

+
You do, from commit one. The repository is created in your GitHub org. Infrastructure is provisioned in your cloud account. We don't host your stack on ours and we don't lock you in.
