Who this is for / When to use
This article is for users building funnels with upsell or downsell steps who experience problems with product visibility, one-click purchase behavior, redirects, pricing, or inventory handling.
What an upsell product does in a funnel
An upsell product allows customers to make an additional purchase after the initial checkout using a one-click action that charges the same saved payment method. Upsells and downsells are configured through funnel steps and button actions, not the original checkout form.
Why an upsell product is not appearing in the funnel
An upsell product does not appear when it is not added to the funnel step or the step changes were not saved.
How to fix
Confirm the product is attached to the correct funnel step
Save the funnel step after adding the product
Steps
Open the funnel.
Select the upsell step.
Open the Products tab.
Select the upsell product from the list.
Click Save.
Why the upsell button is not triggering payment
The upsell button does not charge the customer if the button action is not set to a one-click upsell or downsell.
How to fix
Set the button action to One click up/down sell product
Select the correct product
Steps
Open the upsell funnel page.
Click the upsell button.
Open Button Actions.
Select One click up/down sell product.
Choose the correct product.
Save the page.
Why the upsell product price is incorrect
Incorrect pricing appears when the product price or price override is misconfigured.
How to fix
Verify the product’s base price
Remove or correct any price overrides
Steps
Go to Payments > Products.
Open the upsell product.
Confirm the price type and amount.
Return to the funnel upsell step.
Re-select the product and save.
Why customers are not redirected after purchasing an upsell
Customers are not redirected when the post-purchase action is not configured on the upsell button.
How to fix
Set a post-purchase action such as Go to Next Step
Steps
Edit the upsell button.
Open Button Actions.
Set Sale Actions to Go to Next Step or another destination.
Save the page.
Why the upsell product is not charging the customer’s card
Automatic charging fails when payment integrations are not connected or the one-click action is misconfigured.
How to fix
Confirm a payment provider is connected
Ensure one-click upsell is selected
Steps
Go to Payments > Integrations.
Confirm a payment provider is connected.
Verify the upsell button uses One click up/down sell product.
Save and test again.
Why the upsell button is not functioning at all
The upsell button fails when it is linked to the wrong action or product.
How to fix
Reconfigure the button action and product selection
Steps
Open the upsell page.
Select the button.
Confirm Button Actions and Products are correctly set.
Save and publish the funnel step.
How to set up a downsell product
Downsell products are configured using the same process as upsells with a downsell-specific button action.
Steps
Create the downsell product.
Open the downsell funnel page.
Edit the downsell button.
Select One click up/down sell product.
Choose the downsell product.
Save and test.
Why the upsell product shows incorrect availability or quantity
Inventory-controlled products fail when quantity limits are reached or inventory is disabled.
How to fix
Review inventory settings for the product
Steps
Go to Payments > Products > Inventory.
Open the upsell product.
Confirm inventory quantity and availability settings.
Save and retest.
How upsell orders are processed
Upsell and downsell purchases create separate orders and are not merged with the original checkout transaction.
