Magento’s default inventory (MSI) is Magento’s native foundation for managing Magento stock across multiple sources. Multi-source inventory Magento 2 allows merchants to control sources, stocks, salable quantities, reservations, etc.
Magestore’s Magento 2 inventory management software goes beyond MSI’s basic source-level visibility and stock updates. The software provides advanced end-to-end Magento retail inventory management capabilities, including stock transfer, stocktaking, inventory adjustment, purchase orders, detailed Magento 2 inventory reports, and more.
In simple terms, MSI helps you know where stock is, while Magestore multi-site inventory management helps you manage how stock moves, changes, and supports daily retail operations across channels.
