Shopify Plus development in Los Angeles

LA is the center of American DTC. The brands being built here are setting the pace for commerce globally, and they need platforms engineered to match.

‍

Flux works with US-based brands on Shopify Plus projects spanning custom builds, headless architecture, platform migrations, and ongoing retainers. We bring 14 years of Shopify-exclusive expertise and a senior group that's delivered 150+ stores.

‍

With our headquarters in Melbourne and people in LA and London, we cover US business hours natively and operate across three time zones.

‍

What we do for US brands

‍

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, Salesforce Commerce Cloud, 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. 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.

Are you based in Los Angeles?

Yes. We have people in LA working directly with US-based clients during US business hours. Our headquarters is in Melbourne, Australia, with additional presence in London - giving us global coverage across three time zones.

‍

Do you work with US brands outside of LA?

Absolutely. We work with brands across the US. Most collaboration happens over video calls and shared project tools, regardless of where you're based.

‍

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 assess fit during a paid Discovery phase before any build begins.
