How to Use "Assign to Variant"? Link Stock and Price of Shopify Variant to Option Value
Our app supports product option inventory management, allowing specific options to be grayed out when out of stock and ensuring that inventory updates automatically when a customer purchases an option.
This feature, called "Assign to Variant," links an option to a specific Shopify variant, syncing stock and price automatically. This feature is available in our $19.99/month plan:
In your Shopify store, create a draft product with different variants.
Assign stock levels and prices to each variant.
Example:
Black variant: Stock = 5, Price = $0 (only tracks stock).
White variant: Stock = 0, Price = $1000 (tracks both stock and price).
Navigate to the Assign to Variant section in the app.
Select the corresponding Shopify variant for each option.
If a variant is out of stock, the assigned option will be grayed out automatically.
If a variant has stock (for example 4 stocks), then the option linked with this variant will also have 4 stocks
When a customer purchases an option, the inventory updates in real-time (e.g., black stock reduces from 5 to 4).
If you do not want these variants to appear as active products in your store, you can keep them in draft mode in Shopify.
By following these steps, you can prevent customers from selecting out-of-stock options while keeping your inventory automatically updated!**
