Obviously, the simplest solution would be for the client to share their account details or add us as ‘team admin’, but that is not what this is about.
- Add us to your iOS Developer Program as ‘team member’.
- Create a ‘Distribution Certificate’, if you haven’t got one already.
- Create a ‘App Store Distribution Provisioning Profile’.
- Export the ‘Distribution Certificate’ assets and send the export and password to us. (For security sake, it’s a good idea to send us the password via other means than the exported certificate. E.g. by phone/SMS.)
- Ensure all relevant contracts have been signed.
- Create the application record in iTunes Connect. Ensure that the app record status in iTunes Connect is ‘Waiting for Upload’.
Question (forgive me if this is what you already meant, but just for clarity): Is this how you have the client receive all payments for paid apps and your account to show up as the link for the "More by Developer"?
