# Guesty add-ons at website checkout

The add-ons your guests see at checkout on your website come from Guesty. To offer one:

1. In Guesty, create the item as an **Additional Fee**.
2. Enable the **Booking Engine upsell** option on that fee.
3. Let it sync to your website, where it appears at checkout for the guest to select.

When a guest selects an add-on, it is added to the Guesty quote, paid with the booking, and shown on the reservation in Guesty.

Still stuck? [Contact the HomeRunner team](https://homerunner.io/contact/) with your site address and what you tried, and we take it from there.
