Melbourne. Flux HQ.

Shopify Plus development from Melbourne

Flux started in Melbourne in 2012 and it's still where most of our work happens. From here, we design and engineer Shopify Plus commerce platforms for brands across Australia, the US, and the UK.

‍

Melbourne is home base. It's where our founders, our core engineering, and our design leads operate from. With people also in Los Angeles and London, we cover three time zones and work with brands wherever they are.

‍

14 years of Shopify. 150+ stores launched. $500M+ in client revenue. The focus has always been the same - build commerce infrastructure that performs under pressure and scales with the business.

‍

What we do

‍

Custom Shopify Plus builds

Full storefront design and development on Shopify Plus. UX architecture, responsive design systems, custom checkout extensions, and conversion-optimised layouts built around how your customers actually shop.

‍

Headless commerce architecture

For brands that need complete design control and performance that standard themes can't deliver. We build on Hydrogen, Sanity, and Algolia - sub-second page loads, total frontend flexibility, and content workflows your marketing team can actually use.

‍

Platform migrations

Moving from Magento, WooCommerce, BigCommerce, or custom-built platforms to Shopify Plus. Data migration, SEO preservation, integration mapping, and phased launch planning.

‍

Integration engineering

Connecting Shopify Plus to ERPs, 3PLs, email platforms, review tools, and custom APIs. Cin7, Klaviyo, Gorgias, Okendo, Recharge, and bespoke middleware when off-the-shelf connectors don't cut it.

‍

Ongoing platform partnerships

Post-launch retainers for feature development, conversion testing, integration maintenance, and strategic upgrades. Your store keeps getting better every month, not just at launch.

Where is Flux Agency based?

Our headquarters is in Melbourne, Australia. We also have people in Los Angeles and London, giving us coverage across APAC, Americas, and EMEA time zones.

‍

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.

‍

Can we meet in person?

Absolutely. We're always happy to meet Melbourne-based clients in person for kick-off meetings, workshops, and key milestones.

‍

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.
