Product Configuration

To access the interface provided by this plugin, open an existing product or create a new product at Products > Add New. Once on the product page, set the product type to Variable Product, add the attributes you want to use, create the variations and then navigate to the tab labelled Shared Variation Inventory. A section labelled quantity manager should appear. In this section, there’s two buttons that let you add and save groups. Click the Add Group button to create a new row in the table.

  • Group Name: This field is used to identify the group.
  • Variation(s): This field contains all the variation IDs and attributes of the variations that you want to share the same inventory quantity.
  • Quantity: This field contains the total quantity of the items you want to share stock for. It should represent the total amount of stock that you have.

This is the amount of stock that will be decreased when 1 of this product is purchased (ie. If the product is 10 of the item, put 10 here). IMPORTANT: Please ensure that the “Manage stock?” option is checked for all included variations. If the option is not checked, products may appear as in-stock even when shared stock quantity reaches 0.

You can manage all variation groups in one table from dedicated dashboard located at Products > Shared Inventory by Webis.
  • Search variation group by group id, group name, product and variation name.
  • Quickly manage stock by updating quantity directly from the table

  • Once the plugin is activated and the product is configured with the variation shared inventory, transactions involving the product will now affect the total inventory.
  • Whenever a product in the shared inventory group is purchased, the total quantity will be updated as well as the individual quantities for all variations in the same group.
  • If multiple products in the same group are added to the cart, quantity validation will be based on the total amount available for the shared inventory group.
  • Refunds and cancellation of orders involving products that share inventory will restore stock to the total quantity and update the individual stock totals accordingly as well.

In the case that the total stock of a group has reached 0 and some of the variations in the group still appear as in-stock, please check that the corresponding variation has the manage stock option turned on. In these cases, the quantity validation will still function, but this may affect the product’s display in some sections of the store that list the product.
