A 10% AOV Lift Where Most Brands Don't Even Look: The Checkout


DiamondRensu sells lab-grown diamond and moissanite engagement rings on Shopify Plus, where a single cart routinely crosses $1,000. At that order value, the checkout isn't a payment form, it's the moment of maximum buyer anxiety and maximum revenue opportunity. Using Checkout Boost, DiamondRensu rebuilt that moment with AI-powered upsells, conditional messaging, and precise discount logic. All without a single line of code

Challenges & Solutions

(03)

Testimonial

"We always treated checkout as the page customers just had to get through, never as a page that could actually grow the business. Checkout Boost changed that completely. The upsells felt natural from day one, and within the first month our average order value was up 10% and we were capturing orders we simply weren't getting before. What surprised us most was the enterprise-grade conditional customization, the logic this precise usually needs a development team, and we run it ourselves. Our VIPs get offers nobody else sees, gift messages arrive with the order instead of in my inbox, and checkout finally looks like us. We used to dread touching this page. Now it's the part of the store I'm proudest of." - Ankit
