Health-tech manufacturer: Multi-instance Shopify Plus across EU, UK, and US for a €400M business. ERP and PIM synced every 15 minutes across 100+ markets.

The Challenge

Managing a Shopify Plus operation at €400M scale across three major geographies is a fundamentally different problem from managing a single-market store. The client’s infrastructure had to handle multiple instances, each localized for language, pricing, and inventory, while drawing from the same underlying backend systems. The opportunity for data inconsistency was constant: product data maintained in a PIM, inventory and order data flowing through an ERP, and three distinct storefronts that customers expected to reflect accurate, real-time information. The manual and semi-manual processes that had served the business in earlier stages were no longer tenable. When ERP and PIM data drifted out of sync with what customers saw on-site, the consequences ranged from operational overhead to fulfillment failures to customer dissatisfaction. In a health-tech context, where product specifications can carry clinical relevance and accuracy matters to the purchasing decision, the tolerance for data error is low. The company also needed to maintain performance stability during peak commercial periods product launches, promotional campaigns, and seasonal demand spikes without the downtime or degradation that would result in revenue loss and reputational damage.

The Approach

Gradion designed and delivered a multi-instance Shopify Plus architecture with separate, fully localized storefronts for the EU, UK, and US markets. Each instance was configured for the specific language, currency, pricing structure, and inventory logic relevant to that geography giving customers a market-native experience while keeping the underlying infrastructure coherent and maintainable. The ERP and PIM integration was custom-engineered via proprietary APIs to ensure that product data and inventory levels sync automatically every 15 minutes across all three instances. This cadence was selected to balance operational accuracy with system load providing near-real-time data consistency without overloading the backend systems that the wider business depends on. The result was a significant reduction in the manual effort and data-reconciliation overhead that had previously been required to keep storefronts accurate. Makaira was implemented as a headless CMS layer, giving the client’s content and marketing teams fine-grained control over on-site content across all three storefronts without requiring developer involvement for routine updates. Shopify Payments API was integrated to ensure the checkout layer was optimized for conversion and regional payment preference. Gradion retained an ongoing maintenance mandate to proactively monitor and address performance issues, particularly in the run-up to and during peak demand periods. This relationship moved the client from reactive firefighting to a model where instability was identified and resolved before it affected customers.
