# Cross-sell

> Configure cross-sell prompts to suggest complementary items during checkout and increase Average Order Value.

<Info>
  Cross-sell is a marketing tool that prompts diners to add complementary items before they check out. It appears on Scan-to-Order, Kiosk, and Atlas Online.
</Info>

## What cross-sell does

When a diner adds a triggering item to their cart, Atlas shows them a suggestion to add something that goes well with it — a popup on the menu and a section in the cart.

## Where it appears

* **Scan-to-Order** — diners ordering from the QR menu
* **Kiosk** — self-order kiosk in-store
* **Atlas Online** — your online storefront

## Set up a cross-sell group

1. In the Merchant Portal, go to **Marketing tools → Cross-sell**.
2. Click **Create new cross-sell group**.
3. Add a name and description for personal reference. This would not show to diners.
4. Choose the **trigger products** — the items that, when added to cart, will show the suggestion.

   </Frame>
5. Choose the **suggested products** — what you want to recommend alongside them.

   </Frame>
6. Save. The group is live immediately across Scan-to-Order, Kiosk, and Atlas Online.

## Limitations

* The popup and the cart section are always shown together, i.e., you can't enable just one.
* Products need to be in the menu. The suggestion only shows when both the trigger and product to promote is in the menu.
* Each product can only be assigned as a trigger to one group. Assigning it to another group removes it from the previous group.

## Common use cases

* **Increase AOV** by putting popular or high-margin items in front of diners at the right moment.
* **Highlight new items** by attaching them as suggestions to your best-sellers.

<Warning>
  Don't use cross-sell for drink upsells on a specific dish (e.g. "add a drink to this burger"). Use [Modifier Groups](/menu-builder/create-menus) on the product instead — they're built for required or optional add-ons tied to a single item.
