Gambio to Shopify Migration

The Challenge

A German online retailer ran its shop on Gambio, with JTL-Wawi handling products, stock and fulfilment in the back office. The Gambio storefront had become a constraint: slow, hard to extend, and dependent on plug-ins for the pricing, checkout and up-selling features that set the business apart.

The business wanted a faster, more flexible storefront on Shopify. It could not afford to lose product data, customer history, open vouchers, search rankings or a single day of sales, and it could not replace its operational processes at the same time.

Our Role

Over six months we worked embedded in the project across every level - development, DevOps, architecture and product:

• Architecture: Kept JTL-Wawi as the leading system for merchandise data and replaced only the commerce layer (JTL-Wawi ↔ Shopify → customer). Back-office continuity was separated from storefront modernization, which cut migration risk
• Data migration: Mapped Gambio and JTL objects onto Shopify’s data model (products, variants, collections, metafields, SEO fields) and transferred products, customers, orders and vouchers, together with landing pages and SEO content
• Custom storefront development: Rebuilt the business-critical pricing, checkout and up-selling features in Liquid rather than stacking third-party apps, so key behaviour stays under direct development control
• Integration & launch: Configured the JTL-Connector sync, built the legacy URL redirect map, reconciled data before cutover and switched production without downtime
• Product: Worked with the client on scope and priorities, and decided which Gambio behaviours to rebuild, simplify or drop

Results & Impact

The shop moved from Gambio to Shopify with full data transfer, zero launch downtime and preserved SEO value, on a faster storefront with custom conversion features. The architecture let the business modernize the customer experience without touching the stock, SKU and fulfilment workflows its team relied on every day.

Why this matters for our clients: Many German shops run on Gambio, often alongside JTL-Wawi, and reach the same limits: slow search and pages, hard-to-maintain plug-ins, and fear of losing data or rankings in a migration. We know Gambio’s data model and its constraints from the inside. Whether the right answer is to modernize an existing Gambio shop or migrate away from it, we treat data, integrations, SEO and cutover as one system.
