Shopify Development
Tech Inject is a Shopify development agency delivering custom themes, headless storefronts, Shopify Plus builds, and ERP integration for D2C and B2B brands. We build stores that are fast, conversion-focused, and deeply integrated with your business systems.
Most Shopify agencies install a theme and call it done. Tech Inject builds Shopify stores that are genuinely custom — from the storefront design to the backend integrations that make your operations run.
We work with D2C brands launching their first store, established retailers moving from WooCommerce or Magento, and B2B businesses needing Shopify Plus with wholesale pricing, account management, and ERP integration. If your Shopify project needs real development work — custom sections, Hydrogen storefronts, complex app builds, or a bespoke backend — we're the right team.
What's included
Everything we build into every engagement.
Custom Theme Development
Pixel-perfect Shopify themes built to your design or from scratch. Fast-loading, mobile-first, and built with clean Liquid that your team can maintain.
Headless Shopify (Hydrogen)
Shopify Hydrogen storefronts for brands that need maximum performance, full design freedom, or multi-region customisation beyond what standard Shopify allows.
Shopify Plus
Shopify Plus builds for high-volume and enterprise brands — custom checkout, B2B features, multi-store setups, and automation via Shopify Flow.
ERP & Backend Integration
Connect Shopify to your custom ERP, inventory system, or 3PL for real-time stock sync, automated order routing, and fulfilment status updates.
Custom Shopify Apps
Build private Shopify apps for functionality that no off-the-shelf app provides — custom pricing engines, configurators, or merchant tools.
Platform Migrations
WooCommerce, Magento, or BigCommerce to Shopify migrations with full product, customer, and order history preserved.
How we work
Fixed scope. Weekly demos. No surprises.
-
Store Audit & Discovery
We review your current store (or design brief), identify integration requirements, and define the Shopify architecture — theme vs headless, app requirements, and integration scope.
-
Design & Prototype
We design your Shopify theme or storefront in Figma — desktop and mobile. You approve every page template before development starts.
-
Theme or Hydrogen Build
Development in sprints with a staging store you can review at any time. We build custom sections, integrate apps, and connect your backend systems.
-
Performance & Conversion Optimisation
We test LCP, INP, and CLS. We review checkout flows, product page structure, and mobile UX before launch.
-
Launch & Post-Launch Support
Phased go-live with DNS cutover support, team training, and 90-day post-launch support included in every Shopify engagement.
Right fit
Who this is built for.
- D2C brands launching or redesigning their Shopify store
- Wholesale and B2B businesses needing Shopify Plus with trade pricing
- Retailers migrating from WooCommerce, Magento, or a custom-built store
- Businesses needing Shopify deeply integrated with a custom ERP or 3PL
- Brands that want a premium, design-forward Shopify store — not a template
Before you hire us
Straight answers to the questions we always get.
Something else on your mind? Ask us directly — we reply within one business day.
We can do both. For brands wanting full design control, we build custom themes from scratch. For faster launches, we start with a quality base theme (e.g. Dawn) and heavily customise it. We recommend based on your budget and requirements.
Shopify Hydrogen is Shopify's framework for headless storefronts — it gives you full control over the frontend and significantly better performance. You need it if you want maximum Core Web Vitals scores, complex custom UX, or multi-region customisation. Most businesses are fine with a standard Shopify theme.
Yes — this is one of our specialities. We build custom integration layers between Shopify and ERP systems (whether custom-built or off-the-shelf) for real-time inventory sync, automated order routing, and fulfilment updates.
Yes. We migrate product catalogues, customer records, and order history from WooCommerce, Magento, or other platforms to Shopify with data integrity checks and URL redirect mapping for SEO preservation.
