iPhone payment portal development

Question

A client has asked me about building an iphone app that can take restaurant orders.

I have the resources to get this app done, but I had a few questions.

*Will this app require a portion of the sale to go to apple (if so how much?)

*Whats the best way to integrate a payment portal to this?

*Will I have to/should I have someone authorize the payments?

Thanks, All feedback is appreciated.

Answer 1

To answer your question: "Will this app require a portion of the sale to go to apple (if so how much?)"

Apple only takes a cut when someone downloads an app, not when someone uses an app
