We can make this module compatible with QloApps if you want. And this will be a Paid Customization.

No, any module developed for Prestashop (such as Reward System Module by Webkul) follows the criterions of e-commerce.
For any Prestashop module to work on QloApps we will have to make it compliant with all the nuances of Hotel commerce which are very different from that of e-commerce.
Hence, we will have to make the Reward system module compatible with QloApps.
If you want us to make that module compatible with QloApps please raise a ticket.
