Shopify Development & Optimisation

Service Overview

Shopify powers over 10% of all e-commerce globally, and for good reason — it provides a stable, scalable foundation that lets merchants focus on growing their business rather than managing infrastructure. But vanilla Shopify quickly reveals its limitations as brands scale: template-constrained storefronts that look like every other Shopify store, checkout experiences that can't be customised without Shopify Plus, and integration limitations that force operational compromises. Techglock unlocks Shopify's full potential.

Custom Themes That Convert: We build Shopify themes from scratch — not template modifications — designed specifically around your brand identity, product catalogue architecture, and conversion optimisation hypotheses. Every element is optimised for Core Web Vitals, with lazy loading, image optimisation, and critical CSS extraction ensuring sub-3-second load times that both Google and impatient shoppers demand.

Headless Shopify for Scale: For high-growth brands that need the flexibility of a custom frontend without abandoning Shopify's battle-tested commerce engine, we build headless Shopify implementations using Next.js or Nuxt.js frontends connected to Shopify's Storefront GraphQL API. Headless delivers superior performance (Core Web Vitals scores 30–50% better than theme-based implementations), complete design freedom, and the ability to power multiple storefronts — web, mobile app, in-store kiosk — from a single Shopify backend.

Frequently Asked Questions

The questions clients ask most often before kicking off a shopify development & optimisation engagement.

Do you build Shopify themes from scratch or customise existing ones?

Both, depending on your goals. For brand-led merchants who need a unique storefront we build fully custom themes on Liquid or headless Shopify with Next.js (Hydrogen). For faster launches, we customise premium themes (Dawn, Impulse, Prestige) with bespoke sections, A/B-tested PDP layouts, and conversion-optimised checkouts. A custom theme typically lands at $12,000–$28,000; a themed build is $4,500–$9,500.

Can you migrate our existing store from WooCommerce or Magento?

Yes — we have migrated 100+ stores from WooCommerce, Magento, BigCommerce, and custom platforms. Standard scope covers products, customers, orders, redirects (critical for SEO), reviews, content pages, and subscriptions. Migrations take 3–6 weeks depending on catalogue size and customisations. We rehearse the full migration on staging before any production cutover so there is zero data loss.

Can you integrate Shopify with our ERP / CRM / 3PL?

Yes. We have shipped integrations with NetSuite, SAP, Microsoft Dynamics, Salesforce, HubSpot, Klaviyo, ShipStation, ShipBob, and dozens of 3PL platforms. We build via the Shopify Admin API, GraphQL Storefront API, or off-the-shelf middleware (Celigo, MESA, n8n) depending on transaction volume and budget.

How do you improve Shopify store conversion rates?

We start with a CRO audit covering heatmaps, session recordings, GA4 funnel analysis, and Shopify report data. We then ship a prioritised list of A/B tests: PDP layout, cart drawer vs page, checkout flow, upsell placement, trust signals, and mobile speed. Average conversion lift across our last 12 Shopify clients was 28% within 90 days.

Are you Shopify Partners?

Yes — we are a Shopify Partner agency with certified developers across Liquid, Hydrogen, Shopify Functions, and Shopify Markets. We get direct partner support, early access to new APIs, and a dedicated partner manager.
