Three time zones.
One team. One focus.

We design and engineer Shopify Plus stores for brands that have found product-market fit and are ready to scale. That covers conversion-focused UX, headless builds on Hydrogen, and the product data AI agents need to find, compare and buy from you.

Fixed-price builds. Stores built for people and AI agents. Headless when the theme is the limit. Support that continues after launch.

Fixed-Price Builds

We scope a Phase 1 build and price it. That's the number. No hourly billing that creeps up, and no "we found extra complexity" email in week 6. If scope changes, we talk about it openly and you decide.

Built for AI Agents

AI agents now search, compare and buy for your customers. We build Shopify Plus storefronts, product data and checkout so agents can read your catalogue and complete an order. Found, our weekly AI visibility index for Australia, the US and the UK, shows which brands they recommend.

Async Sprint Delivery

Tuesday kickoff with scope locked. Friday delivery on a Loom walkthrough. You review Monday and Tuesday. You get deliverables, not updates about deliverables.

Strategic Design

UX architecture built around how your customers shop. Conversion-focused layouts, responsive design systems and checkout flows that cut drop-off and lift average order value.

Advanced Engineering

Shopify Plus builds, headless Shopify on Hydrogen, Sanity and Algolia, complex integrations, and migrations from Magento, WooCommerce and BigCommerce. Product data and checkout that AI agents can read and buy through.

Platform Partnerships

Retainers for feature development, integration upkeep, conversion testing and platform upgrades, plus keeping product data and feeds ready for AI agents.

Beyond the build. We operate. Headless when the theme is the limit.

Most agencies ship a site and move on. We stay. Ongoing retainer, async weekly sprints, stack monitoring, integration maintenance. We care about what happens at 3 AM on Black Friday because that's when your commerce infrastructure earns its keep.

14 years on Shopify. 210+ stores and $1.5B+ in client GMV, for brands like 2XU, Quad Lock, Thankyou, Lo & Co and Byron Bay Cookie.

Flux is a Shopify Plus Partner. We build headless Shopify on Hydrogen, Oxygen, Sanity and Algolia from Melbourne, Los Angeles and London. You get sub-second pages, full design control and a Sanity studio your marketing team can edit without a developer. We recommend headless when the theme is the constraint, and we'll tell you when a well-built theme is the better call.

Carwyn Cellars, Lo & Co Interiors, The Coffee Company and Projecta all run headless Shopify Plus builds from Flux. Each ships with structured product data and schema, so search engines and AI agents can read the catalogue.

Frequently Asked Questions

If you have more questions, we're happy to answer them - just reach out.

How do you price projects?

Fixed-price Phase 1. We scope it, price it, and that's the number. No hourly billing. No surprise invoices. If scope changes, we discuss it openly and you decide whether to add or defer. Post-launch work runs on async retainers with sprint durations.

What tech stack do you build on?

Shopify Plus first. For headless Shopify we build on Hydrogen, Sanity and Algolia, and we only recommend it when the theme is the constraint. Every build ships with structured product data and schema so search engines and AI agents can read your catalogue.

How does your delivery process work?

Async weekly sprints. Tuesday kickoff with scope locked. Friday delivery via Loom walkthrough. You review Monday and Tuesday. No standing meetings, no status calls. A project manager holds the scope and a senior engineer leads the technical build.

What happens after launch?

Most agencies ship a site and move on. We stay. Ongoing retainer, async weekly sprints, stack monitoring, integration maintenance. We care about what happens at 3 AM on Black Friday because that's when your commerce infrastructure earns its keep.

What size brands do you work with?

$5M-$100M+ in annual ecommerce revenue. Brands that have found product-market fit and are ready to scale. Brands that care about how their platform performs, not just how it looks. If you're building a category leader, we should talk.

Where are you based?

Melbourne, Los Angeles, and London. Three time zones, one team. Your commerce stack has coverage when your US customers are shopping, your UK market is browsing, and your Australian warehouse is shipping.
