Hi Gsglawson,
We offer backend services where you can write the logic of managing the above feature like who will receive the payment, their payment history and profile details. However, the real cash management logic is not available. Lots of developers use custom code and Storage service to manage the purchases. please have a look at this link to get started with App42 SDK and let us know if you need any help from our side.
Regards,
Himanshu Sharma
