Shopify Development Services in Melbourne
From day-one store builds to complex Shopify Plus environments, here is how Sigma helps Melbourne businesses compete on Shopify.
Custom Shopify Store Builds
Sigma builds Shopify storefronts from the ground up, designed around your brand identity, product catalogue, and the buying patterns of your Melbourne customers rather than a generic brief.
Theme and Liquid Development
Sigma develops custom Liquid themes engineered for speed, accessibility, and conversion, giving your store a distinctive look and experience that competitors cannot replicate with a standard template.
Shopify Plus and Headless Builds
For enterprise-scale requirements, Sigma delivers Shopify Plus configurations, advanced checkout customisation, and headless storefronts built with React, Next.js, and the Shopify Storefront API.
Migration and Replatforming
Moving from Magento, WooCommerce, or BigCommerce? Sigma migrates products, customer data, order history, and URL structures while protecting your organic rankings and revenue throughout the transition.
App and Systems Integration
Sigma connects Shopify with your ERP, Salesforce CRM, 3PL, and payment providers so orders, inventory, and customer data flow automatically without manual reconciliation.
Optimisation and Retained Support
After launch, Sigma improves page speed, increases conversion rates, manages WCAG accessibility compliance, and provides ongoing maintenance through retainer or time-and-materials support.

Why Sigma
Why Melbourne Businesses Choose Sigma for Shopify
Melbourne expects substance from its partners – not just capability claims. Here’s what Sigma actually brings to a Shopify engagement.
01
Commerce is our core discipline
eCommerce accounts for a significant portion of Sigma’s delivery work, across Shopify, Adobe Commerce, BigCommerce, and WooCommerce. We are not a generalist agency that builds stores between other projects.
02
Senior engineers on every build
You work with experienced Shopify engineers, not junior developers supervised remotely. Sigma’s delivery team carries a median of over eight years of hands-on commerce engineering experience.
03
Two decades of commerce delivery
Founded in 2004, Sigma has delivered projects across 16 countries for clients ranging from early-stage startups to Fortune 500 enterprises. We have seen what succeeds at every stage of growth.
04
Certified, secure, and compliant
ISO 27001:2022 and ISO 9001:2015 certified. SOC 2 and GDPR-aligned practices, WCAG accessibility experience, and engagements structured around the Australian Privacy Principles.
Certifications
Certified. Not Just Claiming to Be.
Melbourne’s business community values substance over claims. These aren’t borrowed partner logos. They’re active certifications held by the engineers on your project.

Frequently Asked Questions
What does a Shopify developer in Melbourne do?
A Shopify developer designs, builds, and customises online stores on the Shopify platform. The work covers custom theme development in Liquid, Shopify Plus configuration, app integration, ERP and CRM connections, headless storefront builds using React and Next.js, and ongoing performance optimisation after launch.
Should my Melbourne business use Shopify or Shopify Plus?
Shopify suits most growing DTC and retail brands well. Shopify Plus makes sense when you need fully customisable checkout experiences, advanced automation through Shopify Flow, management across multiple storefronts, or significantly higher API rate limits. Sigma will evaluate the right tier for your business before any build begins.
Can you migrate my existing store to Shopify?
Yes. Sigma migrates stores from Magento, WooCommerce, BigCommerce, and older custom-built platforms. Every migration includes product data, customer records, order history, and full URL redirect mapping to protect your organic search rankings through the transition.
How long does a Shopify build take?
Timelines depend on catalogue size, theme complexity, and the integrations involved. A focused Shopify build typically takes four to eight weeks. Shopify Plus or headless projects with multiple integrations take longer. Sigma provides a detailed timeline once the scope is defined, so there are no surprises during delivery.
How much does Shopify development cost in Melbourne?
Cost scales with the design complexity, custom functionality, and integrations your project requires. Sigma scopes every engagement to your specific goals and provides a clear, itemised estimate before any work begins. There are no hidden fees after scope is agreed.
Do you build headless Shopify stores?
Yes. Sigma builds headless storefronts on React and Next.js, powered by the Shopify Storefront API, for businesses that need faster page performance, complete design freedom, or a single front end that spans multiple sales channels. Headless is best suited to businesses with the technical infrastructure to maintain the additional complexity.
Do you provide Shopify support and maintenance after launch?
Yes. Sigma provides post-launch support on retainer or time-and-materials arrangements, covering platform and theme updates, performance monitoring, conversion rate optimisation, WCAG accessibility compliance, and new feature development as your store grows.
Why choose Sigma for Shopify development in Melbourne?
Sigma brings more than 20 years of commerce delivery experience, a team of 400+ specialists, and ISO 27001:2022 certified security practices to every engagement. Melbourne and Victorian businesses work with senior Shopify engineers from day one, not account managers who hand the work to offshore juniors.
