Who we are
Flux is a Shopify Plus ecommerce agency for brands that have outgrown their first store or first agency. Since 2012 we've built storefronts, product systems and customer journeys for how people and AI agents discover, compare and buy.
We're the engineering partner: Shopify Plus migrations, headless rebuilds for high-volume stores, agentic commerce readiness and long-term partnerships that keep improving the store after launch. Every engagement starts with an agreed scope.

Products
Three ways in: Lift, Run and Build. Most brands start with one and add the others as the store grows.
Get found across Google, ChatGPT and Perplexity. We structure your content, entities and answers so search engines and AI surface your brand when buyers ask. A 100-day partnership with targets you can check.
Agents that take on repeat work across ops and marketing, inside rules your team approves. Storefronts and product data are set up for two buyers at once: the person, and the AI agent acting for them.
Rebuilds, replatforms and the systems behind high-volume Shopify Plus stores. The engineering partner for brands that have outgrown their current build.















Built for the AI era
The commerce stack is changing faster than most brands realise. AI isn't just analysing stores anymore. It's starting to operate them. Shopify has already shipped MCP servers that let AI agents read your catalogue, query inventory and take action programmatically.
The brands that will use this well are the ones built on structured data, clean integrations and API-first architecture. That's how we build.
The gap between stores built this way and stores that weren't is already measurable, and we publish the measurements.
Every week we ask ChatGPT, Perplexity and Google AI the questions shoppers ask in Australia, the US and the UK, and track which brands they recommend.

Insights
How we work, what we build and how projects start.
Every project starts with a paid discovery phase to define scope, technical requirements and priorities. You get a clear proposal with the scope and timeline before any design or development begins, and there's no hourly billing during the build. After launch, most clients continue with Run for ongoing development, optimisation and AI agents.
Yes. Design, engineering, strategy - all done by our core group of senior specialists. The same people work across every project. We don't outsource offshore or rotate through developers you'll never meet. The people on your kickoff call are the same people building your infrastructure.
A standard Shopify Plus build runs 8-12 weeks from kickoff to launch. Headless builds or projects with complex integrations typically land in the 12-18 week range. Every engagement starts with a Discovery phase to lock in scope, technical requirements, and priorities before design or development begins. That upfront work is what keeps timelines tight and prevents scope creep mid-project.
Mostly mid-market brands that have found product-market fit and have outgrown their first store or first agency. Our clients range from high-growth DTC brands upgrading to Shopify Plus through to established retailers running complex multi-region or B2B and DTC operations.
We've built on most major ecommerce platforms over the past 14 years. Shopify Plus consistently wins for scaling brands because of its reliability, ecosystem, and total cost of ownership. You're not paying for server infrastructure, security patches, or platform maintenance. With headless architecture though, you get full frontend flexibility without the overhead of managing a custom stack from scratch.
Yes. We've migrated brands from Magento, WooCommerce, BigCommerce, Salesforce Commerce Cloud, and custom-built platforms onto Shopify Plus. Migration is more than moving data - it's rethinking your information architecture, URL structure, integrations, and customer experience for a platform built to scale. We handle the full process: data migration, SEO preservation, custom integration mapping, and a phased launch plan.
Agentic commerce is when an AI agent acts for the buyer. It searches, compares, fills a cart and completes the purchase, often without the buyer opening your store. If you sell on Shopify you are already exposed to it, because Shopify syndicates catalogue data to AI surfaces by default. Readiness means machine-readable pricing and availability, attribute-complete product data, and a checkout that doesn't break for a non-human buyer. The Agentic Commerce Assessment scores all of it.
Yes. We work with brands across Australia, the United States and the United Kingdom, with team in Melbourne, Los Angeles and London, so there's cover across three time zones rather than one office and a Slack channel. Most engagements run remotely regardless of market.
Yes. We treat post-launch as a roadmap, not a to-do list - prioritising features, optimisations, and integrations based on what's actually driving revenue. You're not locked into a long-term contract, but the brands that get the most out of their Shopify Plus investment are the ones that keep building after go-live.
