# Does an accepted Post-Purchase Offer create a new order in Shopify?


### Overview
In Shopify, when a customer accepts a post-purchase upsell offer, the additional product is added to the original order, rather than creating a new order. This integration ensures a seamless fulfillment process and accurate order management.

A Shopify store’s anatomy looks like this:

| **Landing Page > Product Page (PDP) > Cart > Checkout > Post-Purchase (optional) > Thank You page**

When you have post-purchase offers set up, a customer can add to their initial purchase with an upsell that appears on a page after they’ve checked out.

But how does this work in your Shopify backend? Does it create two offers? What about fulfillment?

###### How It Works

1. **Customer Completes Initial Purchase**: After finalizing their initial order, the customer is presented with a post-purchase upsell offer.
2. **Customer Accepts Upsell Offer**: If the customer accepts the offer, the upsell product is added to their existing order.
3. **Payment Processing**: The customer's payment method is charged a second time for the total amount of the upsell product.
4. **Order Update**: The original order is updated to include the upsell product, and this modification is reflected in the order history.

###### Benefits of This Approach
The Shopify checkout can be modified by apps using checkout extensions. The post-purchase page is such an extension. 

* **Streamlined Fulfillment**: By consolidating the upsell product into the original order, the fulfillment process remains efficient, avoiding the complexities of managing multiple orders for a single customer transaction.
* **Accurate Order Tracking**: All items purchased, including upsells, are tracked under a single order number, simplifying inventory management and customer service inquiries.


|| This is all integrated and built into the UpsellPlus app and allows you to create a customized post-purchase page that fits your store and products.
