How Mustard Made Supercharged Growth with Shopify Plus

Overview

Mustard Made started with a simple idea: bring bold, colorful lockers into homes and offices. Sisters Becca and Jess Stern combined their passion for design with an eye for quality, launching a line of premium lockers that stand out in any space. As demand rose in Australia and the U.K., the founders planned a U.S. expansion. But growth hit limits on their existing platform. They needed a robust solution to manage multiple regions and scale fast.

The Challenge

Faced with booming sales and a plan to enter the U.S. market, Mustard Made struggled with three separate sites and manual tweaks. Toggling between platforms ate up hours, and promotional tests led to slow page loads. They wanted an all-in-one system to consolidate regions, improve site speed, and add conversion tools like wishlists and upsells without writing custom code.

The Solution: Shopify Plus

Upgrading to Shopify Plus unlocked global storefront management under one dashboard. In just two weeks, the team redesigned their theme, set up toggles for Australia, the U.K., and the U.S., and launched new merchandising features. Built-in A/B testing, personalized product recommendations, and cart-level upsells were activated without external plugins, speeding up checkout and serving targeted offers.

Implementation Details

Working with Shopify Plus experts, the Stern sisters tackled theme migration, data transfer, and custom scripts. They deployed a mobile-first design to cut load times, integrated a wishlist tool, and configured upsell rules directly in the admin panel. No extra hosting provider was needed—everything lived on Shopify’s CDN.

Results and Impact

The payoff was immediate. With global sites running smoothly, Mustard Made saw a 158% revenue surge year over year, a 42% boost in returning customer rate, and a 147% jump in site traffic. Personalized recommendations and cart offers lifted average order value by 15%. Now the brand can launch new markets in days instead of months.
