I think your problem here is that you're misunderstanding the customer option in the stripe dashboard.
A typical use would be you register a customer and once you've done that you can charge their card as required, i.e., they are still sending you money, which I believe isn't what you want.
Two options I can see for you.
It's possible to transfer money from your Stipe account to a 3rd party bank account or credit card. See stripe transfers and also this FAQ
Alternatively there is a now Stripe Connect which might just be the ticket for you.
Good luck!
