Here's the story. My client wrote a book, and I (for the first time) created the Kindle/EPUB version for him. To see how this works, I just uploaded it to KDP under MY account. I used MY checking account info and MY SSN. (I don't have his info yet).
My client is technically-challenged, but of course he should get any royalties/payments, not I. Should I (option #1) get his bank info, etc. and get him setup with KDP? Or (option #2) give him the website and let him do it? If #2, I'm thinking I have to get his account info anyway to upload the book again under his account.
I would set up a kdp account for him using all his details, upload the book for him, and tell him not to mess with any settings after giving him his password. That way you are out of the picture once its done, and he is up and running just like any other newbie.
Better he change his password as well, so its secure.
I have often thought KDP dashboard could benefit from the create space system. Both are Amazon companies and CS has an awesome system of building your book, where kdp feels a bit archaic though it does work.
Did you know Amazon's Create Space pays UK authors via EFT, while KDP still says its impossible?
