# Checkout Add-ons

> Optional products shown during checkout, including defaults and cart visibility.

Checkout Add-ons are optional products customers can add during the main checkout flow.

<Info>
  Find this module in **Shopify Stores** > **Edit Checkout** > **Offers**.
</Info>

## How it works

Use add-ons for simple, low-friction offers that belong inside checkout. Use Upsell Offers for post-purchase offers shown after the initial order.
