Custom storefronts, marketplaces, and checkout flows for UK D2C brands, Shopify merchants, and custom-build retailers.
Engagement
Compliance posture
What you get
You bring the product and the brand. We bring the engineering — payment-flow-fluent, conversion-focused, and built to handle peak traffic.
Headless and traditional storefronts built around your brand — not a theme you fight against on every update.
Multi-vendor marketplaces with vendor onboarding, commission splits, and product approval workflows.
Stripe, Square, and custom checkout flows that reduce abandonment and keep cardholder data out of scope at our layer.
Recurring revenue models with flexible billing cycles, trial management, and churn reduction tooling.
How we work
Four phases, same rhythm every engagement. Payment architecture and compliance scoped in discovery so there are no mid-build surprises.
Map your product catalogue, fulfilment flow, and compliance touchpoints. Payment architecture scoped upfront.
Conversion-focused wireframes, checkout prototypes, and mobile-first layouts — reviewed with your team.
Agile delivery with payment-flow integration testing. Stripe / Square sandbox validation, load testing, and end-to-end order flow coverage.
Go-live with payment verification, DNS cutover, and a 30-day window where fixes are free while you settle in.
Compliance map
Six frameworks we design against on every e-commerce engagement — with specifics, not hand-waving.
We never store raw card data. Card flows go through Stripe or Square hosted payment fields, so cardholder data does not transit Byte Bridges-built systems. Your SAQ A scope stays minimal — see our Controls Map for the full position on payment processing.
Digital content, goods, and services all have different rules. We build return, refund, and cancellation flows that match what the Act actually requires — not a generic "30-day returns" banner.
Lawful basis for marketing, cookie consent, data minimisation on checkout forms, and subject access request tooling — baked into the architecture, not bolted on before launch.
Pre-contract information, order confirmation emails, and cooling-off period handling built into the purchase flow from day one.
Clear pricing (including VAT), delivery estimates, and cancellation rights displayed at the right points in the checkout — because that is what the regulations require.
Product listings, filters, and checkout flows built to WCAG 2.1 AA, with the WCAG 2.2 success criteria in flight. Screen-reader-friendly cart, keyboard-navigable checkout, and accessible error states throughout.
Proof of work
Our own e-commerce product — built with the same standards we use for client work.
Internal product
A multi-location inventory management platform for independent retailers. Real-time stock tracking, EPOS integration, and automated reorder alerts — built with the same stack and standards we use for client work.
Before you ask
Shopify is the right call for most D2C brands selling under a few hundred SKUs with standard fulfilment. If you need a multi-vendor marketplace, complex subscription logic, or a checkout flow that Shopify Liquid cannot handle, we build custom on Next.js with Stripe. We will tell you honestly in discovery which path saves you money long-term.
Stripe for most UK e-commerce — the API is excellent, fees are transparent, and your card-handling scope stays minimal because cardholder data sits with Stripe (a validated provider), not us. Square if you also have physical retail and want a single provider. PayPal as an additional option if your customers expect it. We do not push a gateway because of referral fees — we push the one that fits your business.
UK VAT rules require you to show VAT-inclusive prices to consumers. We configure tax calculation at the product and checkout level, handle zero-rated and reduced-rate items properly, and generate VAT invoices. If you sell to the EU post-Brexit, we set up the OSS (One Stop Shop) threshold logic. We are not accountants — but we build the system your accountant needs.
Yes. We load-test before launch, use CDN-cached product pages, and architect checkout flows to scale horizontally. Vercel or AWS with auto-scaling means you pay for baseline most of the year and burst capacity when it matters. We will give you realistic numbers in discovery — not a vague "it scales" promise.
The Consumer Rights Act and Consumer Contracts Regulations set minimum standards for returns on distance sales — 14-day cooling-off, specific refund timelines, and rules about deductions for used goods. We build the return request flow, refund processing, and customer communication into the platform so you are compliant by default, not by accident.
Tell us what you're selling — we'll reply within 24 hours on working days with an honest read on platform choice, compliance scope, and a realistic timeline.
