Managing Inventory Quantities

This site contains archived merchant documentation for a version of Adobe Commerce and Magento Open Source that has reached end-of-support. The documentation available here is intended for historical reference only and is not maintained. The Adobe Commerce Merchant Documentation for current releases is published on the Adobe Experience League.

The following information details how to assign sources and quantities for new products or making changes to existing products.

When creating new products, assign sources and quantities during product creation. See Product Types documentation for full instructions. These pages includes Single and Multi Source information for sources and quantities per source.

When first accessing an upgraded Magento with Inventory Management, all products and quantities are assigned to the Default Source. When importing new products via .csv file, they are also assigned to the Default Source.

Single and Multi Source merchants can update sources, inventory quantities, and thresholds per product or in bulk.

Single Source merchants can update product quantities for the Default Source; this is the total amount of products available for sale.
Multi Source merchants can assign multiple sources and quantities per product for each location (warehouses, stores, drop shippers, etc). We recommend having Sources added prior to setting product inventory amounts.

When adding sources and quantities to your products, you can view the amounts through the Product Grid. If you have a high number of sources, hover the Quantity per Source to see the full, scrollable list of sources with current quantities.

Product Quantities per Source

You have the following options to assign inventory to products:

Assigning Sources per Product - Assign sources manually per product in your catalog.
Assigning Quantities per Product - Add on-hand inventory amounts to your products per source. This information is specific for Multi Source merchants.
Bulk Assigning Sources - Assign sources to selected products as a mass action.
Bulk Unassigning Sources - Unassign sources from selected products as a mass action. We recommend using the Transfer Inventory to Source option if you need to transfer inventory and remove the source.
Transferring Inventory to Source - Mass transfer all inventory from one origin source to a destination source.
Importing and Exporting Quantities - Use import and export features to update multiple product SKUs with sources and inventory quantities.
