How We Work
From First Brief to Live Store and Beyond
Sigma follows a structured delivery process that removes ambiguity at every stage.
01
Discovery and Scope
We map your catalogue, integrations, and business requirements before a line of code is written.
02
Design and Architecture
UX wireframes, Liquid theme design, and system architecture are reviewed and signed off before development begins.
03
Build and Integrate
Development is delivered in structured sprints with regular check-ins. Integrations are tested end-to-end before launch.
04
Launch and Retain
Go-live support, post-launch monitoring, and ongoing retainer or time-and-materials (T&M) maintenance keep your store performing long after launch.

App and Integration Development
Sigma connects Shopify to your ERP, CRM, payment, and shipping tools so orders, stock levels, and customer data stay in sync across every system.

Why Sigma
Why Sydney Businesses Choose Sigma for Shopify
Directly acknowledges competitive supply of Shopify developers in Sydney. Positions Sigma on depth and commitment rather than availability.
01
Commerce is our core discipline
E-Commerce makes up a significant share of Sigma’s delivery work – across Shopify, Adobe Commerce, BigCommerce, and WooCommerce. We are not generalists who occasionally build stores.
02
Senior Engineers from Day One
Sydney brands work with experienced Shopify engineers on the build itself, not account managers who delegate to offshore juniors. Sigma’s team carries a median of more than eight years of commerce delivery experience.
03
Two Decades of Proven Delivery
Founded in 2004, Sigma has delivered projects across 16 countries—from growth-stage DTC startups to Fortune 500 enterprises. We know what it takes to succeed at every stage of business growth.
04

Frequently Asked Questions
What does a Shopify developer in Sydney do?
A Shopify developer in Sydney designs and builds online stores on the Shopify platform. The work spans custom Liquid theme development, Shopify Plus configuration, app and system integration, ERP and CRM connections, headless storefront builds on React and Next.js, and ongoing performance optimisation and support after launch.
Should my Sydney business use Shopify or Shopify Plus?
Shopify suits most growing DTC and retail brands. Shopify Plus is the right choice when you need a fully customisable checkout, advanced automation via Shopify Flow, management across multiple storefronts, or significantly higher API throughput. Sigma evaluates the right tier for your business before any build commitment is made.
Can you migrate our store to Shopify?
Yes. Sigma migrates stores from Magento, WooCommerce, BigCommerce, and older custom platforms. Every migration covers product data, customer records, order history, and URL redirect mapping to protect your organic search rankings through the full transition.
How long does a Shopify build take?
A focused Shopify store build typically runs four to eight weeks. Projects involving Shopify Plus, headless architecture, or multiple system integrations take longer. Sigma provides a detailed project timeline once the full scope is defined – there are no mid-delivery surprises.
How much does Shopify development cost in Sydney?
Cost scales with design complexity, custom functionality, and the integrations required. Sigma scopes every engagement to your specific goals and provides a clear, itemised estimate before work begins. There are no hidden fees once 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 Sydney?
Sigma brings over 20 years of commerce delivery experience, a team of 400+ specialists, and ISO 27001:2022 certified security practices. Sydney and NSW businesses get senior Shopify engineers on the work from day one – not account managers who pass builds to less experienced developers.
