Frequently asked questions

Reach out through our contact page or email us at hello@flux.agency. Tell us a bit about your brand, your current platform, and what you're looking to achieve. No formal brief needed - a few sentences is enough to start the conversation. From there, we'll set up a call to learn more about your business and figure out whether we're the right fit. If we are, we'll put together a scope and proposal. If we're not the right fit, we'll tell you honestly and point you in the right direction. No pitch decks, no pressure.

Every project starts with a paid discovery phase. You then get a fixed scope and price for each phase before any work starts, and there's no hourly billing. A bespoke theme and a headless build are priced the same; checkout customisation and complex integrations sit higher.

Most Shopify Plus projects run between 6 and 16 weeks from kick-off to launch. Timelines depend on complexity - theme builds with standard integrations are faster, while headless builds with custom content models and ERP integrations take longer. We give you a realistic timeline during scoping and run a structured process with clear milestones so there are no surprises.

A Shopify theme build uses Shopify’s native Liquid framework. It’s fully integrated, reliable, and suits most brands.

Headless separates the frontend from Shopify’s backend. You still use Shopify for checkout, payments, and order management, but the storefront is built independently (typically with Astro or Hydrogen) and can connect to systems like Sanity.

Neither is better. They solve different problems. Theme builds suit brands that want a robust platform that’s easy to manage and iterate on. Headless suits brands that need deeper control, more complex integrations, or a platform built to evolve beyond standard Shopify constraints.

Most brands don’t need headless. We’ll recommend the right approach for what you’re trying to do now and later. Read more about headless Shopify.

Mostly mid-market DTC and B2C brands that have found product-market fit, are doing real volume and need commerce infrastructure that keeps up. Revenue matters less than whether you treat your ecommerce platform as a growth engine and want a team that does too.

Three things set us apart. First, we only do ecommerce, and we specialise in Shopify and Shopify Plus: 14+ years of deep platform knowledge, while staying open to whatever platform a project needs. Second, we build commerce infrastructure, not just websites. We think about how your storefront connects to your ERP, 3PL, email platform and analytics stack at scale. Third, we're honest about what you actually need. If a theme build will serve you better than a headless project, we'll say so.

We've handled migrations from WooCommerce, Magento 1 and 2, BigCommerce, Salesforce Commerce Cloud, commercetools, Shopify Basic (upgrading to Plus), custom-built platforms, and legacy systems. If it has a database, we can get your data out of it. Every migration is engineered specifically for your business - comprehensive 301 redirect maps, full metadata migration, product and customer data transfer, and clean integration architecture.

Yes. Most of our clients move to a monthly retainer after launch. We handle ongoing development, performance monitoring, conversion optimisation, integration maintenance, and iterative improvements. A retainer means you have a dedicated team that already knows your codebase, your business, and your goals. No re-onboarding every time you want something new, and you always have someone to talk to.

Yes. Design, engineering, strategy - all done by our core team. We don't outsource development offshore to developers you'll never meet. The people on your kick-off call are the same people building your store. Our CTO specialises in Shopify Plus architecture, and our design team works alongside engineering from day one.

Not every brand needs Shopify Plus. If you're doing under $1M in annual revenue and don't need checkout customisation, wholesale channels, or multiple expansion stores, standard Shopify with the right engineering is plenty powerful. Plus makes sense when you need checkout extensibility, multiple storefronts, wholesale or B2B channels, advanced API rate limits, or Shopify Flow automations. We'll tell you honestly which tier fits.

Every project follows the same structure: discovery, design, development, QA, launch, and ongoing support. Discovery is where we learn your business, your customers, your tech stack, and your growth targets. Design and development happen in parallel where possible - our designers understand Shopify's capabilities, and our developers have opinions about UX. We scope the build with clear deliverables and milestones before starting.

Not if it's done properly. We build comprehensive 301 redirect maps covering every indexed URL on your current site. We migrate all metadata, canonical tags, structured data, and sitemap structures. We monitor Google Search Console through the entire transition and fix crawl issues in real time. Rankings should stabilise and improve within 4 to 6 weeks post-launch.

We build clean API integrations between your Shopify store and your operational stack. The most common tools we integrate include Cin7, Klaviyo, Gorgias, Tagalys, ShipStation, Okendo, Xero, NetSuite, and various ERPs and 3PL providers. We build proper integrations using Shopify's APIs and middleware where needed, designed to sync reliably and handle edge cases at scale.

Both can be. Shopify's AI tools, like Storefront MCP and Catalog MCP, work with theme and headless stores. Headless adds structured content: Sanity stores it as data that AI agents can read directly, which helps when your catalogue and content go beyond what Shopify holds natively.

Yes. We redesign existing Shopify stores regularly. We start with a UX audit to understand what's working, what isn't, and where the biggest opportunities are. Not every store needs a ground-up rebuild. Sometimes the smartest move is targeted improvements to your product pages, collection filtering, checkout flow, or mobile experience. We prioritise changes by impact on conversion and customer experience.
