Frequently Asked Questions
What is Shopify development?
Shopify development covers building and customising an online store on the Shopify platform. It includes everything from custom theme design and app integrations to headless builds, Shopify Plus configuration, and post-launch support.
Should I choose Shopify or Shopify Plus?
Shopify suits most growing retailers. Shopify Plus makes sense when you need enterprise-level automation, a dedicated checkout, higher API rate limits, or multi-store management at scale. Sigma helps you assess which tier fits your business before you commit.
Can Sigma migrate our existing store to Shopify?
Yes – and it’s a process Sigma has run many times with a clear methodology behind it. We migrate from Magento, WooCommerce, BigCommerce, and older custom-built platforms to Shopify and Shopify Plus. Every URL redirect is mapped to protect your organic rankings. All product data, customer records, and order history come across completely. You don’t discover what’s missing after go-live.
How long does a Shopify build take?
Timelines depend on catalog size, theme complexity, and the integrations needed. Most builds range from a few weeks to several months. Sigma provides a realistic timeline once the full scope is clear.
How much does Shopify development cost in Adelaide?
Cost varies with the features, custom design, and integrations your project requires. Every engagement is scoped to your goals, and you receive a clear estimate before any work begins.
Can you build a headless Shopify store?
Yes. Sigma builds headless storefronts on React and Next.js, powered by the Shopify Storefront API, when you need faster performance, full design control, or a unified front end across multiple channels.
Can you connect Shopify to our ERP and CRM?
Yes. Sigma integrates Shopify with ERP systems, Salesforce CRM, payment gateways, and shipping tools so your store and back office stay synchronised in real time.
Why choose Sigma for Shopify development in Adelaide?
Sigma brings deep multi-platform commerce experience, more than 20 years of project delivery, and a team that stays with you after launch. Adelaide and South Australian businesses get senior people on every engagement.
