How SDG re-platformed America's largest bookseller onto Shopify: 14M+ SKUs and 750+ stores, headless on Hydrogen and Oxygen, in what Shopify itself called one of the most complex builds in its history.
This migration was easily one of the most challenging and complex builds in Shopify history, and SDG pulled it off in spectacular fashion. SDG is able to come up with solutions on-the-spot for completely unique niche problems faced by complex enterprise merchants, and more importantly they deliver the final product with all of these solutions connected seamlessly together in a highly performant, smooth, and technically rock solid website.
Overview
Barnes & Noble is America's largest bookseller, a household name spanning a national network of stores and one of the country's highest-traffic retail websites.
Re-platforming a business of this size is the kind of program most agencies will not attempt. Barnes & Noble trusted SDG to move the entire operation onto Shopify, and to do it as a true omnichannel experience across web, mobile, and the store fleet.
The challenge
The brief was unforgiving: bring one of the largest catalogs in retail onto Shopify, keep a national store network and a massive online business running throughout, and unify them into a single omnichannel experience.
- A catalog exceeding 14 million SKUs.
- 750+ retail stores tied into online inventory and fulfillment.
- A loyalty and membership program that had to span online and in-store as one.
- Enterprise requirements across B2B, custom payments, gift cards, native mobile apps, and search at extraordinary scale.
The solution
SDG delivered a fully headless build on Shopify Hydrogen, deployed on Oxygen, engineered to hold under national-scale traffic and wired into the systems a retailer of this size actually runs on.
- A headless storefront on Shopify Hydrogen and Oxygen, architected for peak load across 14M+ SKUs.
- A master-class structured-content implementation on Sanity Studio. As a Sanity partner, SDG architected the content model powering the entire headless storefront.
- Shopify B2B for the institutional and wholesale side of the business.
- A custom loyalty and membership integration spanning web and store for a genuine omnichannel experience.
- Native iOS and Android apps built on the same commerce foundation.
- A custom-integrated Google Vertex AI Search layer powering search, browse, and personalization at catalog scale.
- Custom gift card and custom payment method integrations.
The outcome
Barnes & Noble launched on Shopify at a scale few believed the platform could handle: a unified omnichannel experience across web, native apps, and 750+ stores, on a build Shopify itself ranks among the most complex in its history.
