Post-purchase upsells on Shopify, Wix and WooCommerce: what each platform actually allows

Shopify and WooCommerce allow one-click post-purchase upsells, with conditions; Wix doesn’t. On Shopify, a post-purchase page shown after payment can charge the customer’s saved credit card, but not wallets like Apple Pay or installment methods. On WooCommerce, a plugin charges the saved payment method through a gateway that supports it. On Wix, the customer has to enter payment and address details again to accept an offer after the order.

This guide compares what each platform allows, how the charge works, which payment methods qualify, and what to offer.

Post-purchase upsells by platform at a glance

• Shopify: one-click on a post-purchase page, with vaulted credit cards; Basic plan or higher; up to 3 accepted offers; one app per store.
• WooCommerce: one-click through a plugin, with gateways that save and re-charge payment methods (Stripe, WooPayments, PayPal with vaulting).
• Wix: offers on the thank-you page; accepting means re-entering payment and address details.
• Thank-you page offers differ from post-purchase upsells on every platform.

What is a post-purchase upsell?

An offer shown right after the customer completes an order, for an extra product at a special price. The customer has just decided to trust you, and on platforms that allow it, accepting takes one click because the payment method is already known.

Two related offers are easy to confuse with it:

• A thank-you page offer appears on the order confirmation page. Depending on the platform, it may not be able to change or charge the order.
• A follow-up email offer arrives later and is paid as a new order.

The rest of this guide explains each column.

How do post-purchase upsells work on Shopify?

Through a post-purchase app extension: a page shown after payment and before the thank-you page. When the customer accepts, the app charges the card they just used. It’s available on the Basic Shopify plan and higher; only apps that change the information, shipping and payment steps of checkout need Shopify Plus.

Shopify’s own rules decide when the page appears:

• Payment method. The customer must have paid with a credit card that Shopify can vault. Wallets and installment methods (Apple Pay, Google Pay, Amazon Pay, Klarna, Affirm), gift cards, and gateways that must retain the card’s security code don’t qualify.
• Order. The order must come through the Online Store channel and be at least $0.50. Orders with local delivery, or with duties and multiple currencies, don’t qualify.
• Limits. A customer can accept up to three post-purchase offers per checkout, and only one app per store can run them.
• Access. The post-purchase extension is still a beta feature: it works freely in development stores, and live stores need access approved.

Shopify’s newer thank-you and order status page extensions can also show offers, but Shopify states that they can’t change the order directly. That’s why true one-click acceptance happens on the post-purchase page, not the thank-you page.

Can you do a one-click post-purchase upsell on Wix?

No. On Wix, a customer who accepts an offer after the order re-enters their payment and address details. Wix’s thank-you page settings only let you show or hide elements, change the design and edit the text. Apps can add content to the thank-you page through dedicated slots, so an offer can appear there. But Wix’s developer tools give apps no way to charge the payment method the customer just used:

• Items can be added to an order, but the updated order is paid for normally, through a payment page the customer completes.
• Saved cards exist only for members who opt in, and only the merchant can charge them, manually, from the dashboard.

That changes what works on Wix. Put quick add-ons before payment, in the cart or at checkout, where adding one costs a tap. Use the thank-you page for offers worth a second payment step, or for a coupon on the next order. Our guide to upselling on Wix covers each page.

Does WooCommerce support one-click upsells?

Yes, through a plugin and a payment gateway that can charge a saved payment method. WooCommerce core has up-sells on the product page and cross-sells on the cart page, but nothing after checkout. A post-purchase plugin uses WooCommerce’s Payment Token API: the gateway saves a token at checkout, and the plugin asks it to charge that token again when the customer accepts.

Whether it works depends on your gateway settings:

• Stripe and WooPayments: turn on saved cards. Stripe also needs customers to be able to create accounts.
• PayPal: vaulting, and for PayPal accounts, reference transactions, which PayPal approves per merchant.
• Cash on delivery and bank transfer: nothing is charged; the order total simply grows.
• In Europe: a saved-card charge after checkout can be a merchant-initiated transaction outside SCA, but the customer’s bank can still ask for authentication.

Our guide to one-click upsells on WooCommerce covers gateways, failed charges and refunds in detail.

Which payment methods block one-click offers?

Wallets, installment methods and any gateway that can’t re-charge a saved method. Across platforms:

• Shopify: Apple Pay, Google Pay, Amazon Pay, Klarna, Affirm, gift cards and gateways that retain the security code don’t qualify for the post-purchase page.
• WooCommerce: any gateway without saved payment methods, and PayPal accounts without reference transactions.
• Wix: none are blocked, because every acceptance goes through a payment step.

As more customers pay with wallets, a growing share of orders won’t see a one-click offer at all. Plan for it: keep a strong offer earlier in the purchase, in the cart or at checkout.

What should you offer after checkout?

Something that clearly goes with the order, priced well below it. What tends to work on every platform:

• A direct complement: a refill for a device, a case for a phone, a second color of the same item.
• A lower price than the original order, so accepting is an easy decision.
• One offer at a time, with a clear decline option.
• A short time limit, since the offer only exists on this page.
• On Wix, a next-order coupon often beats a second purchase, because it asks nothing of the customer now.

Setting it up with AppSell

AppSell runs post-purchase offers on all three platforms: one-click on Shopify and WooCommerce with supported payment methods, and on the thank-you page on Wix. It also covers the steps before payment, on the product page, in the cart and at checkout, where quick add-ons convert best. See AppSell for Shopify, AppSell for Wix or the AppSell WooCommerce plugin.
