Multi-Warehouse Inventory Management for Magento 2 is a custom Magento 2 / Adobe Commerce module that ECOSIRE builds to order, installs on your store, and supports — it is not an instant download from the Adobe Commerce Marketplace. We engineer it against your exact Magento version, theme and existing inventory setup so it fits cleanly into your codebase under app/code/Ecosire/MultiWarehouseInventory.

The extension extends Magento's native Multi-Source Inventory (MSI) rather than fighting it. Each warehouse maps to an MSI Source, grouped into Stocks tied to your sales channels (websites). On top of that foundation we add what core leaves thin: a consolidated per-warehouse stock grid in the admin where staff edit on-hand quantities inline across every source at once, mass stock quantity updates via CSV or grid multi-select, and priority-and-location-aware source selection that drives both backend shipment allocation and storefront salable-quantity.

Technically it ships as a proper module: a registration.php + module.xml, dependency injection via di.xml, plugins/interceptors around SourceItemsSaveInterface and the inventory reservation flow, observers on sales_order_place_after, service contracts for clean API access, admin ACL resources so warehouse managers see only their sites, and cron jobs that recompute salable quantities and fire low-stock per-warehouse alerts by email. Data is exposed through both REST and GraphQL endpoints so your POS, PIM or 3PL can read live per-warehouse levels.

Because it is build-to-order, scope, fields and integrations are tailored in a short discovery call. You receive the installed module, source code, a deployment runbook, and a defined warranty window. Honest expectation: a typical build runs 2–4 weeks depending on customization and integrations — we agree the timeline in writing before work starts.
