Shopify Development

Quick Answer:

TechInject 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. TechInject 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.

Key Capabilities

Everything we build into every shopify development 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.

Technology

Built with the right stack

We choose technologies based on your requirements — not our preferences. Every stack decision is explained and documented so you own it completely.

How we work

Our Shopify Development Process

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

We work best with businesses that know what they need and want a development partner who will build it properly — not configure a template.
