CASA - A High-Converting Shopify Experience

Helping CASA Boost Speed, Security & Subscriber Retention with Shopify Plus.

With a growing subscriber base and a bold new brand direction, they needed an eCommerce engine to match. After seeing our work with RMIT, CASA approached Sonder Sites to bring their new Figma designs to life—fast.

Their brief: take their vision and deliver a secure, lightning-fast Shopify storefront with multi-factor authentication (MFA), reliable subscription flows, and a seamless customer experience—all before Christmas.

We delivered a fully custom Shopify Plus store that’s fast, future-ready, and frictionless for staff and students alike.

The Challenge

CASA’s existing site was slow, clunky, and underperforming. They were experiencing:

• Frequent subscription issues impacting recurring revenue

• Conversion drop-offs during checkout

• Poor mobile performance and speed scores

• No MFA, leaving their backend exposed

• A disconnect between design vision and live experience

And with the holidays fast approaching, time was tight.

Our Solution

We worked closely with CASA’s internal stakeholders to translate their Figma vision into a fast, secure, and high-performing Shopify experience. We built the theme from scratch, tweaked Bold Subscriptions, integrated third-party MFA, and optimised every step of the customer journey.
