Today most of the retailers have at least one brick-and-mortar store and an e-commerce website. They are two of popular sales channels. The challenge here is creating better inventory integration between these channels.

Magento MSI (Multiple Source Inventory) is a new inventory management solution which provides two different layers of stock:

  • Source stock, the stock that is physically in a source.
  • Aggregate stock, the virtual stock of what can be sold in a sales channel.

Basically, merchants can set-up a new source & new stock which is linked to both of their e-commerce store & physical store. That means all inventory on-hand will be allocated to the online & in-store channels. So when there is a new sales order on a channel, the inventory will be updated & synced to others. We recommend using a POS software which integrated to Magento. It’s better if that is a Magento native solution like Magestore POS.

Limit inventory for online sales channel

In some cases, merchants want to limit the inventory will be allocated for online sales channel because they prefer in-store sales. The benefit here is that allows to saving inventory for the higher priority channel which most of the sales are generated from. Therefore, merchants don’t need to stock too many items in the warehouse. It really helps them to reduce inventory cost.

How it works?

For example, there are 30 items of Neck Cotton T-shirt in Location A.

  • 30 in stock
  • 10 will be allocated for both of online channel & in-store
  • 20 will be allocated only for in-store

That means, you can not sell more than 10 items of the T-shirt via the website, and able to sell up to 30 items to in-store customers. Let see some situations happen below.

Case 1: Customers bought 3 items through the website. The inventory will be updated.

  • 27 in stock
  • 7 for both of online channel & in-store
  • 20 for in-store only


Case 2: Customers bought 5 items at the physical store.

  • 22 in stock
  • 7 for both of online channel & in-store
  • 15 for in-store only


Case 3: Customers bought 7 items on the website.

  • 15 in stock
  • No available item in the website (out-of-stock)
  • 15 for in-store only

How to implement this solution with Magento MSI & Magestore POS?

Base on the requirements of merchant & power of Magento MSI, we suggest to setup sources & stocks as below:

  • Source A1 contains 20 items, links to stock POS-A
  • Source A2 contains 10 items, links to both of stock Web-A & POS-A
  • Stock POS-A will be used for in-store (POS A)
  • Stock Web-A used for online channel
Divide inventory of a location into two different sources
Sold 3 items through the website
Sold 22 items to in-store customers
