Shopify Plus builds
that actually convert.

We're a design-led Shopify Plus agency based in Melbourne. We build custom storefronts, handle complex migrations, and integrate the tools that make ecommerce actually work. No templates. No themes. Just fast, beautiful stores that sell.

What we build on Shopify Plus

Custom Storefronts

Every store we build is custom. We design and develop from scratch using Liquid, Hydrogen, or headless architectures depending on what your business actually needs. No page builders, no bloated themes.

Platform Migrations

Moving from Magento, WooCommerce, BigCommerce, or a legacy platform? We handle the full migration: data, SEO, redirects, integrations, and launch. We've migrated stores with 20,000+ products without losing a single ranking.

Klaviyo + Lightspeed Integration

We built Gather, our own Lightspeed-to-Klaviyo sync tool. We understand email marketing infrastructure at a level most Shopify agencies don't touch.

Custom Apps & Integrations

ERP connections, warehouse management, custom checkout flows, loyalty programs, subscription logic. If the Shopify App Store doesn't have it, we build it.

Hydrogen & Headless

For brands that need maximum performance, we build headless storefronts on Hydrogen and Remix. Sub-second load times, perfect Lighthouse scores, and a shopping experience that feels like a native app.

Brands we've built for

Why brands choose Sonder

We're two people, not twenty. You work directly with the founder and the senior engineer. No project managers, no account executives, no game of telephone.

We build our own products. We run three SaaS products (HUGE, Gather, Follow). That means we understand performance, conversion, and what it takes to ship something people actually pay for. Month after month.

We're design-led but data-driven. Beautiful stores that don't convert are just expensive art. Every decision we make is designed to move product.

How it works

1. Discovery call (free). We learn about your business, your customers, and what's not working. 30 minutes, no obligation.

2. Strategy + scope. We put together a detailed proposal with timelines, costs, and exactly what we'll deliver. No surprises.

3. Design + build. We design in the browser, build fast, and iterate with you weekly. Most projects launch in 6-10 weeks.

4. Launch + optimise. We don't disappear after launch. We monitor performance, fix issues, and help you grow.
