Create Stock
DEVELOP User Guide - This guide provides MSI Develop Branch/Active Development merchant information on Magento Multi Source Inventory (MSI) features and project.
Stocks map your sources to sales channels, providing a direct link to salable quantities and inventories. As orders come in from a sales channel, this stock provides the sources for aggregating inventory amounts for all requested products.
- Sales Channel Support - Sales channels currently include websites out-of-the-box. You can extend sales channels to include custom options like B2B customers groups and store views. Each sales channel can only have a single stock assigned to it. A single stock can be assigned to multiple websites.
- Map to Sources - Each stock can have one or more enabled or disabled sources assigned, calculating the virtual aggregated inventory per product.
- Priority Order Fulfillment - The out-of-the-box Priority algorithm for the Source Selection Algorithm uses the stock's source list from top-to-bottom when fulfilling orders.
All stores start with a Default Stock that must be enabled:
- It is added to all products when installing or upgrading to MSI, automatically assigning products to the default source and stock for immediate access to inventory management.
- You cannot add additional sources beyond the Default Source to this stock.
- It is required and used by Single Source merchants, Bundle products, and Grouped products.
For Multi Source merchants, create and configure stocks as needed to best fit your stores and order fulfillment. When you assign new stock to a sales channel, any pre-existing stock in that sales channel becomes unassigned.
For an overview of features, see MSI features and processes.
If you are a Single Source merchant, meaning you have a single source fulfilling orders to multiple sales channels, you can edit the Default Stock. Assign your sales channels to this stock.
If you are a Multi Source merchant, meaning you have one or more sales channels with one or more sources fulfilling orders, create new stocks as needed. Each sales channel can only be assigned to one stock, with one or more sources as needed. You can edit the Default Stock or leave it alone.

After adding sources to the stock, arrange those sources from top-to-bottom in priority for fulfilling orders. The Source Selection Algorithm (SSA) provides an algorithm Priority using this order when determining shipment and inventory deductions.
The source priority on stocks does not influence assigned sources when editing product inventories.
In this example, the UK Stock has sources assigned out of order for a store and two warehouses in London and a warehouse in Berlin.
 |
|---|
| Initial Sources Added to the Stock |
The merchant prefers to have shipments prioritized from the larger Berlin warehouse, then the London warehouse, the London overflow location, and finally the storefront in London. To reorder, the entries are dragged and dropped in order.

| Updated Source Priority for the Stock |
Stock may be deleted and modified as needed in Magento. Stocks may not be disabled, but any sales channels and sources can be reassigned as needed.
When modifying or removing stocks, we strongly recommend processing orders and shipments that may depend on specific sources.
Important: Deleting a stock can affect salable quantities and unprocessed orders for a sales channel. If you continue using a sales channel, please add the sales channel to another existing or new stock.

You can edit a stock changing the name, associated sales channels, and the assigned sources. If editing your Default Stock, you can only add or remove sales channels.
If moving sales channels between stocks, we recommend completing any open orders and shipments that may need access to the assigned sources.
If you add a sales channel already associated with another stock, it is unassigned from the previous stock. This will affect the available, mapped sources and inventory salable quantities for the sales channel. For example, moving a sales channel from a US Stock to a UK Stock may have different sources for all inventory.
If you unassign a sales channel without adding it to another custom stock, it will be assigned to the Default Stock.
