How Hismile Scaled Global Sales by 500% with Shopify

Introduction

Hismile, an Australian brand selling teeth-whitening and oral-care products with playful flavors and bright packaging, faced a recurring problem. Their WooCommerce site crashed whenever demand spiked, especially after influencer posts or product drops. Lost orders and frustrated customers signaled that it was time to switch to a more robust platform.

The Challenge

Before Shopify, Hismile’s store struggled under traffic floods. Each product launch drove thousands of visitors in minutes, and their WooCommerce setup simply buckled. Behind the scenes, the small team spent hours patching servers and praying they held up. There was zero margin for error and limited headcount made complex infrastructure management unfeasible.

The brand also wanted to expand overseas without adding developers or devoting time to data-centers. They needed speed, reliability, and flexibility in one package. Any solution that required them to inflate the tech team was a non-starter.

The Solution

Hismile chose Shopify Plus to eliminate crashes and simplify global launches. Within weeks they migrated their catalog, implemented one-page checkout, and tapped into Shopify’s expansion stores feature. Now they have localized storefronts in multiple regions, each handling local currencies, payment methods, and buyer behaviors—with just four in-house developers.

Next, they leveraged the Bundles API to curate product combinations that appeal to different customer segments. Over 80% of orders now include at least one bundle, boosting both cross-sell and average order value. A countdown timer and themed upsells on the one-page checkout add urgency at the final moment.

Results

Since the switch, Hismile has seen:

• 500% year-over-year increase in global online sales
• $300 M in annual revenue in 2023
• 4× growth in average cart size via bundles

Their US store alone is up 374% in sales over the last 12 months. And they no longer lose sleep over site stability during high-traffic launch events.

Conclusion

By moving to Shopify Plus, Hismile freed the team from server maintenance and manual scaling. They can now focus on customer experience, regional marketing, and creative upsells. Smart use of expansion stores and APIs means global growth without extra developers—letting Hismile punch way above its weight.
