The Magento 2 multi source inventory system is a game-changer that addresses complex logistics challenges.
Also, you don’t need to worry about the sales channel and products either. Still, this is a relatively new feature, and below we are sharing a complete guide with you. Whether you’re planning to upgrade Magento 2 to the latest version or just exploring its capabilities, understanding MSI is essential.

How to Implement Multi Source Inventory in Magento 2?
When it comes down to multi source inventory Magento 2, it can be easily integrated into Magento 2.3.0 version. In this section, we are sharing the implementation instructions for store admins using the Magento 2 MSI user guide principles. The process is straightforward when you follow the correct steps.
Source Management
Step one is all about source management because the source is the ultimate element of every new inventory in Magento 2 inventory systems. The source represents the physical area where a product is situated. The location can be a distribution center, warehouse, drop-shipper, or brick-and-mortar store.
Adding a New Source
Store admins can add a new source and choose the available product quantity for every source (even if it’s single). In the section below, we are sharing instructions for adding a new source in multi source inventory Magento 2.3. This process is crucial for effective inventory tracking.
Configuration Steps
Open the admin panel to go to inventory by selecting the store’s option. From the inventory tab, click on sources, and the source grid will show off the enabled default sources. If you are using a single source code, every product is assigned to the name by default.
Now, tap on “Add new source,” and you may enable the multi-source mode if there are different locations. Next, just open the general tab, enter the product name, code, GPS location, and description of every source (code and name are essential parameters of every source while description will only be available on the backend). Lastly, open the source’s address and contact information in the contact info tab, then hit the save and continue button to save the configuration.
Stock Management
Step two is about managing stocks, and stocks will map the sales channel for outlining available inventory and source locations. The sales channels are restricted to the Magento website, and stocks can be assigned on different websites, and every sale channel will be connected to one stock. In the section below, we are sharing steps for managing stocks in Magento multi source inventory.
Creating and Configuring Stocks
Open the stores, scroll down to inventory, and open stock. Look for the default stock (it cannot be disabled), and the default stock will be assigned to the main website and default source with single-source mode. Now, tap on “add new stock” to enable the multi-source mode.
Then, enter the name in the respective field, choose the sales channel, and assign the specific source. This configuration is essential for proper inventory management Magento functionality. The system automatically syncs all changes across your platform.
Manage Catalog Product Inventory
This step is all about managing catalog product inventory and helps attach sources to products in Magento 2 inventory management. In the section below, we are sharing instructions for you. This process ensures your products are properly allocated across all sources.
Assigning Sources to Products
Open the catalog and scroll down to products. Move down to the action column and press the “edit” button to open the edit page of the product. Now, scroll down to the source section and tap on the assign button.
Setting Stock Status and Quantities
From this page, select the sources that you have to assign and hit the done button (you can also outline the stock status, quantity, and low stock notification information). This feature works seamlessly with other multi source inventory Magento 2 capabilities. The interface is intuitive and user-friendly for administrators.
Salable Quantity Management
Whenever a customer places an order, the salable product quantity will reduce, but the product count remains the same. This is because the product count will reduce only when the shipment or order is fulfilled using multi source inventory Magento 2 processes. The system maintains accurate tracking throughout the entire order lifecycle.
Source Selection Algorithm
This is the last step and is about managing the search selection algorithm. The Magento 2.3 multi source inventory selection algorithm uses data about products, customers, stock, address, delivery location, and sources to help merchants determine which orders can be transported while ensuring high product margin. This intelligent system optimizes fulfillment efficiency across all your locations.
What Are the Features of Magento 2 Multi Source Inventory?
Source Management
Source management in Magento 2 MSI can check product stock wherever products are shipped from and are stored. It allows store admins to create manual sources for every location of products. Users can then set the available product number for every source in the configuration menu of products.

Stock Management
Store owners will have access to channel assignments for every group and multiple source grouping with this Magento 2 multi source inventory feature. The system provides comprehensive control over how inventory is allocated. Businesses can create custom stock configurations based on their specific requirements.
Source Selection
This is an algorithm designed with Magento 2 MSI and allows online merchants to choose the physical location closest to customers and develop a shipping location using multi source inventory Magento 2 intelligence. The algorithm considers multiple factors including distance, stock availability, and shipping costs. This optimization leads to faster delivery times and reduced shipping expenses.
Manage Catalog Product Inventory
This feature is related to stocks because you eventually have to assign a source for each product. In addition, store owners can allocate available quantities for every product. For this purpose, they have to switch on the “notify quantity” option, which means you will get a notification when product stock starts running low.
In simpler words, it helps with inventory management Magento operations. The notification system prevents stockouts and ensures continuous availability. Merchants can set custom thresholds for each product category.
Saleable Quantity
Magento multi source inventory has systematic steps since you’ve to create a source, allocate the stocks, determine the product quantity, and every store is connected to the website. When these steps are completed, the module will automatically evaluate the product to deliver a saleable product quantity. Whenever the customer places a new order, the module will deduct the product quantity and send an alert notification.
Stock Status and Customer Communication
In addition, it notifies the action change. Consequently, “out of stock” will appear when the product quantity is zero. That being said, customers will be informed about limited stock if they want to buy more than available stocks.
Performance Optimization Benefits
It can enhance performance through system offloading in Magento 2 inventory management. The real-time updates ensure accurate inventory representation. This transparency builds customer trust and reduces order cancellations.
Order Management
When orders are placed, the multi source inventory Magento 2.3 feature will reserve the ordered product until the order is fulfilled. Moreover, shipping will be provided when the payment gateway is complete. Consequently, the purchased product quantity will be detracted from the source quantity.
Automated Fulfillment Processing
It has a source selection algorithm as well (it has to be manually decided). The system automatically prioritizes fulfillment based on predefined rules. This automation significantly reduces manual processing time and errors.

It allows users to sign in to the POS checkout from a single link because you only need a browser (no, you don’t even need an internet connection because offline mode is available). In addition, inventory can be synchronized in real-time between the backend and web POS.
Real-Time Inventory Synchronization
Not to forget, the POS functions will help connect to Magento multi source inventory data and showcase inventory from the stock. Lastly, it can update the POS orders to backend systems. This seamless integration ensures consistent inventory data across all channels.

The advanced MSI helps manage everything within the Magento environment while picking suitable warehouses (the location is chosen according to stock availability and the closest location).
Enhanced Algorithm Capabilities
