PROBLEM VS SOLUTION

Where Marketing Sites and Stores Fall Short

Pain PointGeneric ApproachHardened Soft
Slow pages kill conversionsPage builders generate bloated HTML and unoptimised assetsNext.js SSG/SSR, image optimisation pipeline, and CDN-first delivery

Checkout friction drives abandonmentGeneric Shopify theme with no customisationCustom Shopify storefront or headless commerce with tailored checkout UX
No inventory or order visibilityBasic Shopify admin, no custom reportingCustom order management, inventory alerts, and fulfilment dashboards
Poor Core Web Vitals = poor rankingsPerformance as an afterthoughtLighthouse audits baked into every sprint — we don't ship slow pages

CORE CAPABILITIES

What We Build Under Marketing & Commerce

Marketing & Brochure Sites

  • High-performance Next.js or Astro builds — static where possible, dynamic where needed

  • Headless CMS integration: Sanity, Contentful, Prismic — edit content without a developer
  • SEO foundations: semantic markup, structured data (JSON-LD), Open Graph, sitemap

Landing Pages & Campaign Sites

  • Conversion-focused layout engineering — above-the-fold, CTA placement, form design
  • A/B testing infrastructure: split URLs, variant tracking, analytics events
  • Lead capture: form handling, CRM integration (HubSpot, Salesforce, custom)
  • Performance budget enforced: under 1s LCP on 4G, 90+ Lighthouse score

E-Commerce Stores

  • Custom Shopify storefronts using the Storefront API — full design freedom
  • Headless commerce builds: Next.js frontend + Shopify or custom product catalogue
  • Checkout customisation: upsells, bundles, subscription logic, discount rules

Payments & Checkout

  • Stripe integration: one-time payments, subscriptions, saved cards, tax handling
  • Shopify Payments and third-party gateway support
  • Custom checkout flows for complex products (configurators, booking, custom orders)
  • PCI-compliant implementation — no card data touches your servers

Performance & SEO

HOW WE WORK

Marketing Site & Commerce Delivery Process

WEEK 1

Discovery & Architecture

Goals, conversion targets, content structure, commerce requirements, and performance budget defined. Tech stack selected and CMS/commerce platform agreed before design begins.

WEEKS 1–2

Design & Component Library

Full design in Figma: page layouts, component system, mobile breakpoints, and animation spec. Approved before frontend development starts.

WEEKS 2–6

Build & Integration

Frontend build, CMS integration, payment and commerce wiring, CRM connection, and analytics instrumentation. Lighthouse audits run on every PR.

FINAL SPRINT

QA, SEO & Launch

Cross-browser and device QA, Core Web Vitals sign-off, redirect mapping from old URLs, DNS migration, and launch monitoring. Post-launch support included for 2 weeks.

WHY HARDENED SOFT

What Every Marketing & Commerce Engagement Includes

A fast page isn't a nice-to-have — a 1-second delay costs 7% of conversions. We treat performance as a hard engineering requirement, not a post-launch afterthought. Every site we ship has a 90+ Lighthouse score, CMS your team can edit, and 100% code ownership so you're never paying platform fees to access your own content.
FAQ

Common Questions About Marketing Sites & E-Commerce

Can you migrate our existing Shopify store to a headless setup?

Yes. We start with an audit of your current store: product catalogue, theme customisations, apps, and checkout flows. We then plan the migration to preserve SEO rankings, order history, and customer accounts.

Will our marketing team be able to edit content without a developer?

Yes. We integrate a headless CMS (Sanity, Contentful, or Prismic) so your team can manage all copy, images, and page structure without touching code. We include a training session in every handover.

How do you handle international stores with multiple currencies and languages?

Through Shopify Markets for multi-currency and localisation, or a custom i18n architecture in Next.js with hreflang tags, currency detection, and localised checkout. We define the internationalisation strategy at architecture stage.
