How we reduced a 33-hour product import process to under 3 hours, handling 530,000 SKUs with parent products containing over 20,000 variants each.
Our client, a mid-sized fine jewelry retailer, was operating a Shopware 6 store with over 530,000 SKUs managed in their internal ERP system. The catalog included complex parent products with more than 20,000 variants each. Their existing product import process from their ERP to Shopware was a critical bottleneck:
The slow sync cycle meant pricing and inventory were often 24-48 hours out of date, resulting in overselling, pricing errors, and damaged customer relationships.
We built a custom Shopware 6 plugin that integrates with their internal API, creating an optimized import system designed to handle massive product catalogs with complex variant structures:
Implemented multi-threaded batch processing to handle thousands of products simultaneously
Delta sync mechanism to update only changed products, reducing API calls by 85%
Built-in retry logic and error handling to automatically recover from API failures
Admin dashboard showing sync status, errors, and performance metrics
We specialize in building custom Shopware import solutions and ERP/PIM integrations that handle large catalogs efficiently. Let's discuss your project.
