Build an upsell funnel once. It runs on the post-purchase page after payment. Shopify skips that page for some payments, like wallets and pay-later, so the funnel can continue on the thank-you and order status pages, where the buyer pays for added items on a Shopify page. On the post-purchase page the buyer sees the total with shipping and tax before paying. A yes can lead to a matching add-on, a no to a cheaper one. An accepted post-purchase offer adds a second payment to the order.

• Funnels with a different next offer after a yes and after a no
• The same funnel on the thank-you and order status pages
• Live total with shipping and tax on the post-purchase page
• A/B test two offers, or two whole funnels, against each other
• Show each offer by product, order value, customer tag or past orders
