Projecta Power — Headless Shopify Plus Case Study

The Brief

Projecta is a category leader in portable power and automotive accessories across Australia and internationally. Their product range is deep and technical, spanning battery chargers, jump starters, inverters, and solar panels, each with complex specifications that matter to their audience.

‍

The existing platform couldn't support the scale of their catalogue, the technical depth of their product information, or their ambitions for international expansion. They needed an architecture that could handle high-volume product data, serve multiple markets, and deliver the kind of fast, responsive experience their customers expect.

The Approach

We built a headless Shopify Plus architecture that decoupled the frontend from the commerce engine, giving Projecta the speed and flexibility to serve rich, technical product content without performance trade-offs.

‍

The UX was designed around how their customers actually research and buy: filtering by vehicle compatibility, comparing specs across product lines, and accessing detailed technical documentation. Every product page was engineered to surface the right information at the right moment in the decision process.

‍

The headless architecture means content teams can update product specs, technical guides, and marketing content independently of the development cycle. Critical for a catalogue of this size and complexity.

‍

For search, we built one discovery bar rather than bolting an AI panel onto the side of it. It returns direct product matches by default and only routes a query to AI when there's no clear match or someone's asked a genuine question, so customers aren't waiting on a model to reason through the easy cases.

The Result

Projecta runs on a platform built to scale with their catalogue and their markets. Technical product pages load fast despite dense spec data, content teams update independently, and the architecture supports international expansion without rebuilding.

‍

Conversion has more than doubled and returning customers now make close to double the share they once did. Sales have grown even as session volume fell, so the store is converting more of the traffic it gets rather than depending on more of it. Checkout abandonment has come down too. Search now gives a straight answer on the easy queries and lets AI take the harder ones, without one slowing down the other.

‍

Projecta's catalogue was built to be too deep and technical for a standard storefront to handle well. It's now deep enough that a single search bar can't cover every kind of question a customer might ask, so the architecture handles that too.
