How to use MSI Backorders for Magento 2

Since the release of Magento 2.3, many enhancements were added to the default Magento features and particularly to the inventory management.

The MSI Backorders extension for Magento 2 allows you to manage the backorders individually for each source through your back-office.

You'll be able to handle your backorders for each product and arrange backorders dates and quantities directly at the source level. 

Manage backorders at the source level

Backorders are taken into account each time there is a check on the products' quantities, for example in the frontend product page, in the cart...

The MSI Backorders extension allows you to manage backorders at the source level.

You can easily manage the backorders for a product in:


Select and Edit a product.

You will have the possibility to manage backorders directly in the Sources tab.


If you untick the Use Default box, you have the choice between 3 options:

  • No backorders
    When there's no stock, it's impossible to order the product.
  • Allow quantity below 0
    Even if there is no stock, the product can be ordered.
  • Allow quantity below 0, and notify customer
    Even if there is no stock, the product can be ordered and the customer will be able to see in the front-office that backorder is allowed for that product.

Backorders Date

You have the possibility to select a restocking date directly from the grid.

Backordered qty

You can define a backordered quantity for each source.

Out-of-Stock Threshold

You can define an out-of-stock threshold for each source. Beyond this value, the product will go out of stock.

If a customer wants to order more items than there are, a notification will appear on the product page.

Used with negative numbers, the out-of-stock threshold will limit the maximum number of backorders possible. The product will then go out of stock as soon as the maximum backorder is reached.

Use MSI Backorders with the extensions of the MSI Suite

The MSI Suite is a package including all necessary extensions to completely improve and enhance the Magento 2 inventory and multi-stock inventory. 

With MSI Backorders, the Suite includes 5 other extensions: 

  • MSI Stock Status
    Display customized and elaborate stock status messages to better inform your customers about the availability of your products.
  • MSI Custom attributes
    Brighten up the assignation of your products to the sources with any kind of custom fields.
  • MSI Permissions

  • MSI Stock Management
    Manage all your stocks inventory directly from the stock grid and get a clear and accurate view of your products' availability thanks to the tree view.
  • MSI Orders Management (coming soon)

License and domains

A license is valid for an unlimited period of time on one single Magento installation

  • If you're using more than one Magento installation, you will have to buy a separate license for each instance.
  • if you're running several domains on a same Magento installation, you will need only one license for all of them.
Although your license doesn’t have a limited period of validity, your support period does. By purchasing an extension, you’ll be granted a 6-month support period for free. Passed this period, you will have to pay for a new one (see FAQ: Extend your Support period)

You can pre-register your live domain to your license in advance.

Thanks to this option, you'll be able to get the extension ready to use on your domain before it goes live.

To pre-register your production domain: 

  1. Go to:
    mY accountLicenses & DOwnloads
  2. Click on  next to the extension you want your domain to pre-register on.
  3. Click on the link at the bottom of the page saying:
    Do you want to pre-register your domain in order to be ready to go live?
  4. Finally, enter your domain name and click on pre-register now .
Attention, this doesn't mean your license is activated. You'll still have to activate it on your new domain when the extension is installed. 

One license is valid for an unlimited period of time on one Magento installation only. However, it is possible to extend or transfer your license in 2 cases: 

  • If you would like to add your testing environments to your license. 
    In that case, it is possible to extend your license to an unlimited number of domains for free.
    For example: or
  • If you want to transfer your license to another live domain.
    In that case, the support period for your license must still be active.

To be able to use MSI Backorders on both your production and testing environments, follow the instructions below:

  1. Download MSI Backorders.
    (see FAQ: Extensions download)
  2. Install MSI Backorders on your environment.

Next step is to activate your license:
Extension activation

Extensions activation

Once MSI Backorders is installed, you have to activate the license. For previous versions, you can activate the license from your back-office:

    1. Go to your Magento admin panel. A message pops up at the top of the page.

      If the message doesn't appear then you must check that:

         1. The Adminhtml_Notifications and Wyomind_Core modules are well enabled.
         2. The HTML output of the Adminhtml_Notifications and Wyomind_Core modules are not disabled in:
      storesconfigurationadvanced advanced
         3. The encryption key well exists in app/etc/env.php:
       return array(
       'backend' => array(
       'frontName' => 'admin'
       'crypt' => array(
       'key' => '1e8f3c6772b7a6a6689c3c8cefa4ccf0'
       /* ... */
    2. Copy your activation key in:
      StoresConfigurationWyomind Your extension

      You can find your activation key in 2 different places:
      In the confirmation email that you received after purchasing MSI Backorders.
      In your Wyomind account:My account Licenses & downloads
      Select MSI Backorders and click on  .

      A new page opens where you'll find your activation key (see below).

    3. In your Magento admin go to:
      StoresConfigurationWyomind Your extension

      Paste the activation key in the Activation Key field and choose between the automatic (yes) or the manual (no) activation method:
      By choosing Yes, the connection to Wyomind license server will be automatic.
      By choosing No, you will have to log on to Wyomind license server yourself.

    4. Click on Save config .
    5. A message appears at the top of your admin panel. Click on that link: 
      Activate it now!
    6. Copy and paste the license code in the License code field from your admin or simply click on Activate now! 

    7. Finally, refresh your cache, log out and log in back straight after, to complete the installation.

When the extension includes other modules, repeat the steps described above for each one, using the corresponding activation keys (each module has its own activation key).

Add another domain to your license

To activate the license on another domain (test, staging...):

  1. Once the extension is installed on the new domain, copy your activation key in:
    StoresConfigurationWyomind Your extension
  2. After having saved the configuration, a notification appears. Click on Add this domain to my license.

  3. A transfer request will then be sent to our team within an hour.
    Once the request is taken care of, you will receive a confirmation email.
    If your transfer request is accepted, you can use MSI Backorders on both environments at the same time.

Note that the order in which you activate your license on your domains does not matter. You can start with your staging/dev/local environment or with your live domain, the process will be the same.

Also, if you have loads of staging domains, or if you are an agency managing load of domains for your customers, please contact us so that we can automatically whitelist these domains.

Once MSI Backorders is installed, you have to activate the license.

For this, you can use the below command line (change the Activation key with the corresponding value):

bin/magento wyomind:license:activate Wyomind_MsiBackorders <YOUR_ACTIVATION_KEY>

To retrieve the list of all the available modules as well as the licenses status, please use:

bin/magento wyomind:license:status


 Among the different status, you can find: 

  • registered = your license is registered
  • pending = you need to run the activation command line
  • invalidated = the license has been invalidated due to a wrong activation key or a license infringement


To activate several licenses at the same time, use:

bin/magento wyomind:license:activate \
Wyomind_Extension1,Wyomind_Extension2 \


bin/magento wyomind:license:activate \
Extension1,Extension2 \
