I am starting to develop apps for clients but I would like to know what is the best way to share with them so that they have full rights to add/modify data and test the apps. What is the best way for me to do this? Not sure if this matters but I have two zoho creator accounts. I have an older $25 account which includes 5 users and I also have a a newer Professional Single account. Some of my clients have newer Professional accounts in zoho creator and others don't have zoho accounts.

Summary: What is the best way to create zoho apps then give clients access to test the apps with real confidential data? Once fully tested and paid for then how would I give them full ownership of the app?
