What it is

A Next.js front end for Shopify: one-screen checkout, shipping estimated on the product page, and a 1.1s largest contentful paint on mobile.

This is the storefront we built for Nebula Commerce, packaged. The case study has the numbers — conversion up 38%, checkout abandonment down 62% — and the reason for both is on the product page rather than in the checkout: shipping is estimated before anyone commits.

It talks to the Shopify Storefront API, so your orders, inventory and fulfilment stay exactly where they are. Nobody in the warehouse has to learn anything.

Content comes from Sanity, with a schema your merchandising team can compose pages from without raising a ticket.

What makes it worth the money

  • 1.1s LCP on mobile Measured on a throttled 4G connection, not on a laptop.
  • The checkout that worked One screen, shipping shown early — the change that moved the number.
  • Editors compose pages 42 components in Sanity, no developer in the loop.

Questions about this one

For the commerce half, yes — the cart, checkout and inventory all go through the Storefront API. The component library and CMS work on their own if you want to lift those out.
