Shopify Plus design and development in Melbourne

Flux is a Shopify agency based in Melbourne, building Shopify Plus storefronts and commerce systems for brands across Australia, the US and the UK. Since 2012, our work has covered custom storefront design, platform migrations, headless architecture and ongoing engineering.

What we build for Melbourne brands

Shopify web design in Melbourne

UX architecture, responsive design, custom storefront development and checkout extensions. Our Shopify Plus development team works around your catalogue, customer journeys and operational requirements.

Shopify developers for custom requirements

Our Melbourne team handles custom storefront features, checkout extensions and integrations. Start with the workflows that standard features do not cover, then define the requirements, testing and ongoing ownership. Explore our Shopify Plus development services for the engineering scope.

Headless commerce architecture

Headless can make sense when your content workflows, customer experience or integrations need more flexibility. It also adds engineering and maintenance responsibilities. We assess the trade-offs before recommending a build on Hydrogen, Sanity and Algolia.

Shopify Plus migrations

Moving from Magento, WooCommerce, BigCommerce or a custom platform? Our Shopify Plus migration process covers data, URL mapping and redirects, SEO preservation, integrations, testing and launch planning.

Systems, integrations and B2B

We connect Shopify Plus to ERP, warehouse, fulfilment and customer systems. Explore our systems and integration engineering or Shopify Plus B2B services if inventory, wholesale pricing or order workflows are the difficult part of your brief.

Ongoing platform partnerships

After launch, our ongoing Shopify support and development covers feature delivery, conversion improvements and integration maintenance, prioritised around the business.

A Melbourne project: Carwyn Cellars

Carwyn Cellars needed its online store to reflect the guided discovery customers experience in its physical bottle shop. Flux designed and engineered a headless Shopify Plus storefront with Prismic CMS, a beverage selection tool and filtering by style, region, producer and occasion.

The project also included a mixed-case bundle builder and Shopify POS integration for online and physical retail inventory. The content team can update the rotating catalogue without relying on a developer for each change. See the Carwyn Cellars brief, approach and delivered features.

For your own project, the question is which customer journeys and operational workflows need to change. Discuss your Melbourne Shopify Plus brief with Flux, including your current platform, integrations and launch requirements.

How a Melbourne Shopify project starts

Start with the problem: what is holding the store back, which systems need to connect, and what needs to change? We work best with brands doing $5M–$100M+ in annual revenue. A paid Discovery phase defines scope, technical requirements and priorities before a fixed-price proposal for design and development.

Melbourne clients can meet us for workshops and key milestones. If you are still comparing partners, use our Melbourne Shopify Plus agency comparison to build your shortlist. If you have a brief, tell us about your Shopify project and we will work through the next step with you.

Does Flux do AI search optimisation for Australian brands?

How much does a Shopify Plus project cost?

It depends on scope. Headless builds typically start around $80K and scale with integrations, regions and content complexity. Every project starts with a paid Discovery phase, then a fixed-price proposal, so you know the build cost before work starts. For platform fees, use our Shopify Plus pricing calculator.

Do you work with international brands?

Yes. While Melbourne is home base, we work with brands across Australia, the US, the UK, and globally. Most collaboration happens over video calls and shared project tools.

What size brands do you work with?

We work best with brands doing $5M-$100M+ in annual revenue that have found product-market fit and are ready to invest in their commerce infrastructure. We evaluate fit during a paid Discovery phase before any project kicks off.
