Overview
Upsell products may have one or multiple variant options (such as size or color). Aftersell handles out-of-stock variants differently depending on how many options a product has, to ensure a smooth customer experience and prevent unavailable selections.
Out of Stock Variant Logic
Products with a Single Variant Option
If a product has only one variant option and that variant is out of stock, it is hidden entirely. For example,
The blue variant for this Notebook product is out of stock
Therefore, on the post purchase page, the blue variant will not show up as an option
This prevents customers from interacting with a product that cannot be fulfilled.
Products with Multiple Variant Options
If a product has multiple variant options, all variant options are displayed, including those that are out of stock. By default, Aftersell will preselect an in-stock variant, if one is available. However, if a customer manually selects an out-of-stock variant, it will be clearly marked as unavailable and cannot be added.
For example,
The blue/small variant for this T-shirt product is out of stock
However, the variant will still appear on the live post-purchase page, but customers will not be able to purchase it if selected.
This approach gives customers full visibility into available options while preventing invalid selections.
NOTE: This logic applies even if all variant settings are unchecked in the editor.
