# How does the post-purchase upsell offer work for customers?

Right after a customer completes their order, Dropify can show them a one-click **post-purchase upsell** page — a single extra offer they can add with one click, without re-entering payment details, before reaching the thank-you page.

## Steps

1. Create and configure the offer itself in the **Upsell Booster** app — see [How do I create an upsell offer with Upsell Booster?](https://help.dropify.shop/en/marketing_email_sms/upsell-booster/) for how to set the product, content, and buttons.
2. Attach the upsell to the specific product on either the product page settings or the landing page settings — it only appears for orders of that linked product.
3. When a matching order completes, the customer is automatically routed to the upsell page before the final thank-you page.
4. If the customer clicks the confirm button, the upsell item is added to their order as a single additional unit; the cancel button skips straight to the thank-you page.

## Common problems

- Upsell page never appears after checkout → confirm the upsell was actually selected in both the product page settings and the landing page settings for the purchased product — creating it in Upsell Booster alone isn't enough to attach it.
- Customer wants to choose a quantity on the upsell page → this isn't supported; the upsell always adds one unit. Offer quantity tiers as product options instead if that's needed.
- Upsell shown doesn't match the product just purchased → check **Variant Matching** in the upsell's settings; if enabled, it only shows when the purchased variant matches the upsell product's available variants, which can make it seem to "not show" for other variants.
