The One-click Upsell Plugin makes it easy to add an upsell button to your shopping cart and order form Thank You pages.
Use the upsell shortcode on any Thank You page or post. Make sure you select the option in Infusionsoft to pass the contact’s information to the Thank You page.
Once the customer clicks the upsell button, One-click Upsell will charge the customer’s last used credit card and place the order in Infusionsoft.
