Yes, we can integrate any payment gateway module to QloApps you required. And it will be a Paid Service.
The cost of the service depends on the efforts required to integrate the payment gateway.
But, we are also running an offer for our customers. If you buy any of our QloApps services billing to a minimum of 750 USD in total then we will integrate one payment gateway of your choice to QloApps for free.
You will have to provide the APIs of payment gateway for the integration if they are not open publically. And if the APIs are publically open then please share the link.
Our store has services for many platforms, to avail the offer you will have to make the purchases in the QloApps category only.
No, a CS-Cart module will not work on QloApps as these two are completely different platforms.
If you want PayU payment gateway then we can integrate it.

And if you have some more requirement then please list them.
Right now, we do not have dev docs for QloApps. So we suggest to every developer to take the help of Prestashop dev docs. If you know Prestashop then you will also be able to develop on QloApps.
But the payment gateways development will be a bit different. We made some small changes while managing the pricing in QloApps. So you will have to keep a check on that.
Now regarding the Prestashop Modules,
We have made changes in Prestashop codes to make it compatible with the hotel industry.
So the PrestaShop modules might not work in the QloApps. But if need some sort of functionality then please inform us we will suggest you the best possible way.
