We are a small startup and in process of launching our product. For now we have digital services (user can add and see data as they entered only be subscribed), but later we would have value added services - including hardware ( devices e.g. Glucometer). Current payment workflow we have uses Razorpay as payment gateway. We have two options: We can either make a web page for the payments to be collected via Razorpay. this will have less impact on the code and implementation. (like there's for Netflix and Spotify where they redirect to browser for payment than in-app purchase) We can add the apple payment gateway for the payments. Questions: What would be the charges in both the scenarios ? E.g. If we take 100rs payment from patient then how much would go to apple in scenario 1 and 2. Is there any support for small startups where apple provides some discount with respect to the payments collected ?
