Upsells on the Confirmation Page
Guests can choose the specified upsells in the system after passing through the General Info and Guest Info during the booking confirmation process. When they can click on the Next: Payment button, a pop-up window of Upsells you created in Zeevou appears:

Guests can select their desired upsells and specify the number of times they need each of the upsells. Then, clicking on the Apply button, they will be redirected to the payment step. However, if they do not need any extra services, they can click on the No Thanks button to continue to the payment step. If there are any special requests, they can click on the Contact Us button and directly message Hosts.
