What is Magento 2 MSI?

First of all, let’s explore the most basic definition of Magento MSI (Multi Source Inventory).

Multi Source Inventory (MSI) is an outstanding feature of the Magento 2.3.0 version. With the support of Magento 2 MSI, it is easier for store merchants to control their single or multi-channel inventories and sale channels. MSI is designed to assist merchant stores in managing their multi-sources of inventory and sales channels from the Magento 2 admin panel. Magento 2 Multi Source Inventory (MSI) is a huge leap that dramatically improves inventory management regardless of the customers and warehouse locations, the type of product, or sales channels.

Amazing Benefits Of Magento 2 MSI

Indeed, Magento MSI offers several amazing advantages that enhance inventory management and improve the overall customer shopping experience.

  • Enhancing physical location management: MSI allows you to manage multiple physical locations or sources, such as warehouses and retail stores. This enables better control and tracking of inventory across various locations.

  • Increasing store sales and improve customer experiences: With improved inventory visibility, you can accurately display stock availability to customers, reducing the chances of overselling.

  • Improving the checkout process: Magento 2 MSI enables efficient order routing and inventory allocation, ensuring that orders are fulfilled from the nearest available source. This streamlines the checkout process and reduces delivery times.

  • Manage Drop Shipping with ease: Multi Source Inventory provides the flexibility to manage drop shipping, where products are shipped directly from suppliers to customers. It simplifies the management of inventory from different suppliers and enables faster order processing.

  • Separate Shipment from Different Warehouses: It allows the store owner to make a separate shipment from a different warehouse with quick delivery service for an order with multiple items, in case a customer wants to receive a particular item in advance.

  • Buy Online and Pick Up In-store (BOPIS): MIS supports the BOPIS option, where customers can place an order online and pick it up from a nearby physical store. This not only improve the customer shopping experience but also drives traffic to your physical stores.

5 Steps to Implement Magento 2 Multi Source Inventory

To make the best use of Magento 2 MSI, you need to follow the given below steps:

Step 1: Manage Sources

What is Magento Source?

As the primary element of the new inventory, a source represents a physical place where the product is located. This location may be a warehouse, brick-and-mortar store, drop shipper, or distribution center. Store owners are allowed to add a new source and set the quantity of the available products for every single source.

Add A New Source

  1. Access to admin panel
  2. Navigate to Stores > Inventory > Source
  3. In the Manage Sources page, the source grid will show you the default source which must be enabled. In a Single source mode, all products are assigned to it by default.
  4. Click to the Add New Source button to allow the multi-source mode if the merchant has several locations.

  1. In the General tab, enter the name, code, description, and the exact GPS location (latitude and longitude) of the source.

Note:

  • Name and Code are required parameters for a source.
  • The description of the source is visible only in the backend.

Then enter the specific contact information and the address of the source into Contact Info section and Address Data section.

Note: Country and Postcode are required fields.

  1. When everything is ready, click to the Save & Continue button at the top right of the screen to save the configuration.

Step 2: Manage Stocks

What is Magento Stock?

In Magento, “stock” refers to the quantity or availability of a specific product in inventory. It represents the number of items you have available for sale. Stocks map a sales channel to source locations and available inventory. In Magento 2.3.0, the sales channels are limited to only Magento websites. A stock can be assigned to multiple websites, while each sale channel can be connected to only one stock.

Add New Stock

  1. Go to Stores > Inventory > Stocks.
  2. In the Manage Stock page, you will see the Default Stock which cannot be disabled. In a Single source mode, the default stock is assigned to the default source and the main website.
  3. Click to the Add New Stock button to allow the multi source mode.

  2. Scroll down to the Sources section, click the Assign button.
  3. In the Assign Source page, choose the sources to be assigned and click to the Done button.

After you save the configuration, it gets shown as below:

Here you can easily define the quantity, the stock status, and modify the default admin threshold for the low stock notification.

Step 4: Manage Salable Quantity

Salable Quantity indicates the inventory which stores can sell through a sales channel. This takes into account stocks in all assigned sources. Different from the previous versions of Magento 2, when the customer places an order in Magento 2.3.0, the salable quantity will decrease while the number of products does not change. The quantity of product decreases only after fulfilling the shipment.

Step 5: Manage Source Selection Algorithm

The source selection algorithm uses data about customers, products, addresses, stock, sources, and order delivery location to help the merchant determine which source order can be shipped most efficiently with the highest product margin. Inventory Management provides two types of Priority algorithms, which are Source Priority and Distance Priority. The algorithm comes up with a source list, together with available product quantities, and deducted amounts as required by the selected algorithm. Thanks to it, Magento 2 stores can plan inventory management strategies more effectively, which greatly reduces costs and increases customer experience.

How to Disable MSI in Magento 2.4

Starting from Magento 2.4, the Multi Source Inventory (MSI) feature is a core part of the platform and cannot be disabled through the admin interface. However, if you want to remove MSI functionality and revert to the default inventory management system, you can follow these steps:

  • Step 1: Backup your Store: Before making any changes, it is important to back up your Magento installation, including the database and files, to ensure you have a restore point in case any issues arise.

  • Step 2: Disable Magento MIS Modules: To disable MSI, you need to disable the MSI modules in Magento. You can do this by connecting to your server via SSH or using a command-line interface and running the following commands from the Magento root directory:
