What platforms do you build e-commerce sites on?

We build on Next.js with Stripe for custom high-performance stores, or Shopify when you need a large app ecosystem. We recommend Next.js for most businesses - it loads significantly faster and ranks better on Google, which directly impacts sales.

How much does an e-commerce website cost?

Our e-commerce subscription starts from £120/month with no upfront cost. One-off builds are available from £2,000 for a product store. Complex stores with custom functionality, multiple currencies, or large catalogues are quoted individually.

Can you migrate my existing store?

Yes. We migrate products, customer records, order history, and URL structures from Shopify, WooCommerce, Wix, Squarespace, and most other platforms. We also set up 301 redirects so your existing SEO rankings are preserved.

Do you handle payment processing?

We set up and test your payment gateway as part of the build. We work with Stripe, PayPal, Klarna, ClearPay, and most UK payment providers. We don't process payments ourselves - all transactions go directly between your customers and your payment provider.

How do I manage my products after launch?

You get a simple dashboard to add products, update prices, process orders, and track stock. We also provide a short walkthrough video so you can manage the basics yourself. For anything more complex, your monthly subscription includes ongoing support.

How many products can my store handle?

There's no hard limit. We've built stores handling hundreds of products with variants, bundles, and digital downloads. For stores over 500 SKUs, we'll recommend the right platform and architecture during the brief.

Do you set up UK tax and VAT?

Yes. We configure UK VAT rules, apply them to the correct product categories, and set up the VAT-inclusive pricing display required for UK consumer retail. If you're VAT registered, we'll set up the appropriate tax codes.

What's the difference between Shopify and a custom Next.js store?

Shopify is easier to manage yourself and has a large app ecosystem. A custom Next.js store is significantly faster, ranks better on Google, and has lower ongoing costs (no Shopify fees). We recommend Next.js for most UK businesses and Shopify only when the app ecosystem is specifically needed.

What makes a great e-commerce website?

A great online store loads in under 2 seconds, works perfectly on mobile, and makes the path from product to payment as short as possible. UK mobile commerce accounts for over 60% of online sales - a store that isn't mobile-optimised loses more than half its potential customers before they even see the checkout.
