Selling and pricing in SAP Store

Hi there..

I have two theoretical questions about selling a SAP NetWeaver Cloud app in the SAP Store.

1.) Before I offer an app: The pricing is my free decision, right!? So I can decide if the buyer have to do a monthly/annualy payment!?

I'm also free according to the quantity - if per user or more-user-licences?

2.) If I would be a partner and had offered a certificated cloud solution: How will the payment flow works? The buyer of my developed app will pay the fixed price directly to me - or does it first go to SAP, so that they get their 15% revenue share? How is the way of the cashflow?

Thanks fore some more inforamtion..
