When filling in the info for the itunes connect for paid apps there are number of things they want fill开发者_如何学编程ed in.

• contact info (which has a lot of different roles. e.g.finance, technical, legal)

How should those be filled out for the individual?

Are they all necessary or not?

Indie developer here. Filled all those as myself in all roles, had no problems since. I vaguely recall I provided an alternative e-mail address in some spot, but I had those aliases all along - sales@mydomain.com, support@mydomain.com, etc.
