For Your Comfortable Home

Astoreo is one of the e-commerce platforms we developed for our long-term partner Packway (formerly Magnet Pardubice), with whom we have been cooperating since 2010. We currently manage twelve of their online stores across Central and Eastern Europe, all built on the Sylius platform. To efficiently manage such a large e-commerce ecosystem, we developed a PIM system for centralized product data management and deployed our own software for bulk product image uploading and optimization — Imageserver. We also implemented product configurators, parallel integrations with multiple ERP systems, and other custom solutions.
