### Introduction 

After a customer makes a purchase, a post-purchase offer (also known as post-purchase upsell or one-click upsell) will show related products just before the order confirmation screen. This strategy takes advantage of the customer's excitement and willingness to buy, leading to a better shopping experience and increased revenue for your brand.

💡 Post Sell is only supported in Stripe checkout.

### Setup

**OMS**

To activate the cross-selling feature to enable your customers to add new items to their existing order after completing the Stripe checkout., navigate to your Store Settings in the OMS **Settings --> Store** and add the following under the **Environment Variables** section. 

**ORDER\_CROSS\_SELL\_TIME\_IN\_MINUTES: **Please specify the duration in **minutes** for users to add items to their cart after checkout. In this example, we are adding a value of 2 minutes. 

**CROSS\_SELL\_POST\_CHECKOUT: **Mark it as **enabled**. This flag sets the Stripe card to be re-used like subscriptions and delays the complete order event until the cross-sell ends.

**CROSS\_SELL\_EMAIL:  enabled **If you wish to inform your customers about the items they have purchased after checkout. A pre-existing template is available in Contentful.

**GitHub**

A new [endpoint ](https://chord.stoplight.io/docs/chord-oms/3e72c4c31d015-cross-sell-order-line-items) (see PR [here](https://github.com/chordcommerce/chord-oms/pull/712))  is added, which accepts items, and then completes the [cross-sell ](https://github.com/chordcommerce/chord-oms/blob/main/app/services/acs/order_completer/cross_sell_completer.rb#L4)state, creating a new charge on the credit card for the new items and sending a new email.
