Multiple things come together to make your upsell available on the storefront.

This article is here to help ensure you have them all checked and are ready for success.

First, the most common reason why your add-on may not be showing on the storefront is that the add-on product isn't available on the storefront.

There are two Shopify inventory settings that affect whether an upsell is showing; the "Track quantity" option and the "Continue selling when out of Stock" option. To check a product's inventory, find it in your Shopify Admin Products Tab.

If this option is checked, there needs to be inventory in the Available column. If there is no stock here, your upsell will not show.

Shopify has four different inventory states. To learn more, check out the Shopify help doc on Inventory States here.

If the product only has one variant, you'll be able to check its inventory by scrolling down to the "Inventory" section.

If the product has more than one variant, each variant will have its own inventory level.

You can check each variant's inventory by scrolling down to the "Variants" section of the product settings and clicking on the variant you wish to check. On the next page the inventory settings will display the same way for that variant as for a single product.

If this option is checked, your product will not track inventory and will 'never sell out.' This also means the upsell will always be available through UpCart. You can learn more about using this setting by reviewing the Shopify help doc on Selling out of Stock Products here.

Is the product's Status marked as Active or Draft? If the product is marked as 'Draft,' it will not show as an upsell on the storefront.

You can find out by checking the product status in your Shopify Admin Products Tab where it will be displayed in the column next to the product name.

Alternatively, you can select the product and then check the top right of its settings and the badge that's next to the product's title! You can learn more about product status states by reviewing the Shopify help doc here.

Is the add-on product a part of the "Online Store" sales channel?

You can check this by opening your Shopify Admin Products Tab, selecting a product, and then checking the "Publishing" section on the top right of the product's settings.

If you do not see a green dot next to 'Online Store,' your product is not active in that sales channel. To add it to the online store, you need to click on the three dots at the top of that section, and select "Manage sales channels" and then select "Online Store".

There are a few limitations to the kinds of products that we can use for upsells. If your product is one of the following below, this could be why you are not able to see it.

UpCart has a few settings that will affect if the upsell is showing in the cart or not. These settings are:

If the box is checked for Show Upsell If Item Already In Cart then all upsells will still show in the cart as expected.

If the box is unchecked then the upsell will not show if it is the same as the product currently in the cart.

Similar to above, if the box is checked for Limit Number of Upsells setting then only a certain number of upsells will show. One reason you may not see your upsell is that it might be a lower-priority upsell.

The upsells module reads the upsell list top-down. It will check the row at the top of the upsell list first, then checks the next row, then the next one after that... until it finally gets to the end of the list of upsells.

Let's say we've set a limit of two upsells and told UpCart to hide upsell products that are already in the cart.

In the scenario below, the Classic Leather Jacket upsell is not showing in the second screenshot because the cart is displaying the Multi Product Upsell products first.

When using manual upsells make sure to check if the product trigger has the product box checked for a product that is in stock, active and available for the online sales channel.

If there are variants for the trigger product, select the variants you wish to trigger the upsell. If there are no variants selected, the upsell will not show.

For example, If there is no stock, your upsell will not show. It will appear like this in your UpCart settings:

If you're using an AI recommendation algorithm to suggest upsells to customers, these are some reasons that no upsells may be showing.

If you are using the 'Related' algorithm, a product must share at least one collection with another product to be considered related. If a product is not in any collection with other products, no upsells will be shown in the cart.

Complementary Products are items that go well with something a customer is already looking at. Shopify’s AI automatically suggests these based on what customers often buy together, however, Complementary upsells must be configured: Learn how here and here.
