Stripe Integration IOS and Android application

The payment gateway is already set in my Ios application and Android application and Admin panels. If not, possible we will have to use a different payment gateway who will be better. Everything is already complete and my application is already live in IOS and ANDROID. In the admin panel we only have the % fees that is already set. Right now, we are using Stripe. It is already set in my application but the only issue that we have is that we can’t find the proper way for the customer to transfer the money from the application to their bank account or stripe account. This is what prevents us from launching the application. I need a freelancer who could complete this .
