I am developing an Mobile app especially for call, conference call and video call. People will topup using Credit card, Debit card or Vouchers. Please let me know if i need to use IPA or can I do without IPA. Using IPA how much of the % I need to pay Apple when a subscriber tops up.
I will have very less margin so I need to understand if this business model makes sense for me if I go with IPA.
