01 / PROBLEM
A 40k-SKU Turn14 reseller stuck on a generic theme. PDPs returned the wrong fitments. The cart abandoned at 81%. Email was a 3% revenue afterthought.
02 / APPROACH
Headless Shopify on Next.js. Year-make-model gating in the URL. Real-time stock surfaced as a confidence signal. Klaviyo rebuilt around the aftermarket buying cycle — research-heavy, fitment-anxious, repeat-window long.
03 / RESULT
Mobile checkout time halved. Repeat-purchase window tightened from 47 days to 22. Owned channels now a third of monthly revenue.
