Seeing ineligible offers in your upsell history? This article will show you some of the main reasons why some post-purchase upsells may not be showing.

Vanga AI is built specifically for the native Shopify Checkout. This means it supports all apps & payment methods that work with the Shopify Checkout. Also, it means the algorithm doesn't show post-purchase upsells for any payment methods unsupported by the native Shopify Checkout, due to its own limitations.

The two types of upsells Vanga AI currently supports are post-purchase upsells and Thank You page upsells. Here are the main differences between the two when it comes to payments:

Post-purchase upsells work with all credit card processors supported by the native Shopify Checkout out of the box.

This includes 3rd party payments that don’t use redirects to complete the payment.

✅ Credit/Debit Cards
✅ Shopify Payments
✅ Shop Pay
✅ PayPal Express Automatic Payments
​
Due to its own limitations, the Shopify Checkout will not trigger any post-purchase upsells if the order is paid with:

❌ Cash on Delivery (COD payments)
❌ 3rd party providers with external payment methods
❌ Wallets (ApplePay, Google Pay, etc)
❌ Installment payments

However, the new Thank You page upsells are not limited and work with all payments and currencies.

✅ Credit/Debit Cards
✅ Shopify Payments
✅ Shop Pay
✅ PayPal Express Payments
✅ Cash on Delivery (COD)
✅ Wallets (ApplePay, Google Pay, etc)
✅ 3rd party providers with external payment methods
