Frequently Asked Questions
What does a Shopify developer in Perth do?
A Shopify developer builds and customises online stores on the Shopify platform. The work covers custom Liquid theme development, Shopify Plus configuration, app development and integration, ERP and CRM system connections, headless storefront builds on React and Next.js, and ongoing performance optimisation after the store launches.
Should my Perth business use Shopify or Shopify Plus?
Shopify suits most growing DTC and retail businesses well. Shopify Plus makes sense when you need a fully customisable checkout, advanced Shopify Flow automation, management across multiple storefronts, or significantly higher API throughput. Sigma evaluates the right tier for your business before committing to a build plan.
Can you migrate my 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 transition.
How long does a Shopify project take?
A focused Shopify build typically takes four to eight weeks. Projects involving Shopify Plus configuration, headless architecture, or multiple system integrations take longer. Sigma provides a detailed project timeline once the scope is defined, so there are no surprises mid-delivery.
How much does Shopify development cost in Perth?
Cost scales with design complexity, custom functionality, and the integrations your project needs. Sigma scopes every engagement to your specific goals and provides a clear, itemised estimate before any work begins. There are no hidden costs 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 Perth?
Sigma brings over 20 years of commerce delivery experience, a team of 400+ specialists, and ISO 27001:2022 certified security practices. Perth and WA businesses get senior Shopify engineers on the work from day one – not account managers who pass the build to junior offshore developers.
