How SDG migrated Canada's largest bookseller from Salesforce Commerce Cloud to Shopify Plus: 12M+ products, 135+ stores, bilingual across the country, with one agency running the entire program.
Overview
Indigo is Canada's largest bookseller and one of its best-loved retail brands, a national chain of more than 135 stores selling books, lifestyle goods, and gifts, alongside a busy ecommerce and mobile-app business. Its Plum Rewards program connects members across every channel.
Replatforming a retailer of this size is the kind of program most agencies decline. Indigo trusted SDG to migrate the entire business off Salesforce Commerce Cloud and onto Shopify Plus, and to run the whole program end to end.
The challenge
Moving Indigo to Shopify meant standing up one of the largest catalogs ever brought to the platform, while keeping a national omnichannel operation running without disruption.
- A catalog exceeding 12 million products and 8 million metaobjects.
- Web, mobile app, and 135+ physical stores kept in lockstep on inventory and fulfillment.
- A fully bilingual experience, English and French, across the entire storefront.
- Deep integration with the enterprise systems a retailer of this scale runs on, from order management to loyalty to tax and fraud.
The solution
SDG ran the entire engagement as the single delivery lead, with every team reporting through us, and built Indigo headless on Shopify Plus at enterprise catalog scale.
- A custom split checkout that lets a customer ship some items and reserve others for in-store pickup in a single transaction.
- Plum Rewards rebuilt as a true omnichannel loyalty program spanning store, web, and the native app.
- Manhattan Active Omni integrated as the order-management backbone, so inventory and fulfillment stay consistent everywhere.
- A bilingual storefront with search, ratings and reviews, analytics, fraud prevention, gift cards, tax, and consent management built in as first-class capabilities.
The outcome
Indigo went live on Shopify in May 2026 with one of the largest catalogs on the platform, a unified omnichannel experience across stores, web, and app, and meaningfully less operational overhead than the system it replaced.
It is exactly the kind of migration most teams will not attempt. SDG ran the whole program, and delivered it.
